　　Cctv newsAccording to the deployment of the Shanghai Municipal Party Committee and Municipal Government, the city has launched nine major actions to clear the social aspects since April 22, and strives to realize the social aspects of the city as soon as possible. Focusing on the hot spots of public concern, relevant departments answered reporters’ questions:

　　About sealing and controllingask

　　1. How long will the city-wide blockade last? When will citizens’ lives completely return to normal?　

　　answer

　　At present, the prevention and control of epidemic situation in Shanghai has reached a critical stage of tackling the problem of social zero-clearing. Our goal is to achieve social zero-clearing as soon as possible, which is an important symbol of winning this big and tough battle of epidemic prevention and control and restoring normal production and living order as soon as possible. Once the social coverage is cleared and the prevention and control effect is continuously consolidated, the social mobility, production and life can be gradually, batch by batch and orderly opened according to the relevant requirements of the "three zones" division until it is completely restored to normal.At present, the epidemic prevention and control in Shanghai has shown a positive trend.I believe that as long as we adhere to the general policy of dynamic zero clearing and work together, a normal life will come soon.

　　ask

　　2. After the division of the three areas, what management measures will be taken for the closed control area, control area and prevention area in the city center? Some communities have not been "out of the sun" for more than 14 days. Why haven’t the control measures been adjusted?　

　　answer

　　According to the relevant provisions of the joint prevention and control mechanism in the State Council, combined with the actual situation in Shanghai, and according to the division of closed control zone, control zone and prevention zone, the city has implemented differentiated prevention and control by zoning and grading. The "7-day closed management +7-day home health monitoring" will be implemented in the closed control area. During the 7-day closed management period, "the area will be closed, and services will be provided at home". In the control area, 7-day home health monitoring was implemented, "People are not allowed to leave the community and gathering is strictly prohibited". The prevention area implements "strengthening social control and strictly limiting the scale of personnel gathering".

　　Considering that the epidemic situation in Shanghai is still at a high level, the population density and agglomeration risk are different between different regions, especially between the central city and the suburbs. For areas where there are many closed control areas in the adjacent areas that may generate agglomeration risks, each district may implement upgrading management.We seeSome prevention areas still require "staying out of the community", mainly to consider preventing agglomeration risks and upgrading them according to "control areas".This situation is more in the central city.This is temporary.With the situation of epidemic prevention and control improving, there are fewer and fewer people in the closed control area, and the control gestures will be adjusted accordingly.

　　ask

　　3. After the social situation is dynamically cleared, what means do we have to sound the alarm in advance in case of the outbreak?　

　　answer

　　We must adhere to the general policy of dynamic zero clearing without hesitation. Dynamic zero clearing refers to finding and eliminating the COVID-19 epidemic together, which will neither make Covid-19 popular in the epidemic area, nor prevent the virus from spreading to other areas. Its essence is "quickness" and "accuracy", in order to try our best to control the epidemic in the smallest range with the fastest time and achieve the maximum prevention and control effect with the least cost.

　　Shanghai is an important port city, and the pressure of "foreign defense input" has been great, so we must be prepared at any time.Specifically, the command system at all levels should always be highly sensitive and efficient, and all fronts should respond quickly and deal with it quickly. Once the situation occurs, we should do a good job in tracing the source of the flow, nucleic acid screening, transshipment isolation, regional control, medical treatment and other work at the first time. We should also comprehensively investigate problems, plug loopholes, and weave a tight epidemic prevention and control network. Strictly implement prevention and control norms, continue to do a good job in supervision and inspection, and continue to optimize emergency plans. Focus on key points such as entrance to the city, foothold, mobility, employment posts, school gates, monitoring posts, etc., firmly grasp the prevention and control on the surface, strengthen closed-loop management for people in key positions, and guard against aggregation risks in important places. We should also strengthen medical research, promote vaccination, and establish personal protection barriers.

　　About nucleic acid detectionask

　　4. Why do we need high-frequency nucleic acid detection and antigen detection?　

　　answer

　　High frequency nucleic acid detection is very necessary. From the occurrence and development of clinical diseases, any pathogen infection has a certain incubation period, and Covid-19 is no exception, and there are certain individual differences in the length of incubation period. From the perspective of detection technology, there is a process of growth and replication in human body after virus infection. If the viral load is lower than the detection limit at the initial stage of infection, the detection may not be positive, and the infected person is difficult to be found, which increases the risk of community transmission. Therefore, it is necessary to dynamically find positive infected people as soon as possible through continuous nucleic acid screening, and realize social dynamic zero clearing as soon as possible.

　　About medical treatment and dispensing

　　ask

　　5. On the one hand, hospitals are required to do everything they can, and on the other hand, they are required to guard against the sense of hospital. Will it lead some hospitals to be afraid to open clinics in order to prevent the sense of hospital? How to be "satisfactory"? 　

　　answer

　　According to the requirements, all emergency departments of medical institutions at all levels in the city must be open under the premise of standardizing epidemic prevention. At present, all districts have established a docking mechanism between communities and medical institutions, set up special classes for special personnel, and opened up channels for medical treatment.Patients with acute and critical illness shall be transferred to the relevant hospital by themselves or the street town or neighborhood committee. If the ambulance cannot be contacted temporarily, the street town where they are located shall arrange the transfer car to be sent to the relevant hospital in time.Villages’ neighborhood committees collect the needs of key populations such as radiotherapy and chemotherapy, hemodialysis and pregnant women, and cooperate with the hospitals determined by the health and health committees in various districts to do a good job in medical security in the sealed-off areas.

　　It should be noted that at present, some medical institutions in this city have been transformed into designated medical institutions for infected people in COVID-19, which undertake the treatment of infected people, and some emergency departments are in the temporary disinfection stage because of positive infected people, which leads to a decrease in the total number of emergency departments that accept non-infected people, which is likely to lead to differences in citizens’ feelings. In this regard, I urge the public to understand.

　　Preventing nosocomial infection is the most important and bottom line of epidemic prevention and control in hospitals.The purpose of preventing hospital feeling is to protect people’s life safety and health and ensure the normal operation of the hospital, which is not contradictory to "all clinics should be opened".We have asked medical institutions at all levels to do a good job in preventing hospital feeling, and have clearly set up "emergency buffer zones" and other ways to open up life channels, while keeping the bottom line of hospital feeling prevention and control, and strive to achieve "both ends meet".

　　ask

　　6, long-term closure, a large number of residents have dispensing needs, Health Cloud has opened dispensing channels, and the public has reported that many drugs are still not available, and there is no way to transport them to the hands. Is there any further improvement plan?

　　answer

　　After the opening of the dispensing channel of Health Cloud, the number of dispensers is very large, the logistics capacity of dispensing is relatively limited, and the waiting delay is longer than the daily time. Relevant parties are making every effort to improve, upgrading and expanding from the aspects of technology and capacity, coordinating postal vehicles to participate in the "green channel" of drug delivery, and "relaying" with drug logistics warehouses and street distribution points to transport to the terminal, in order to meet the needs of the public as soon as possible.

　　At the same time, regarding the prescription of chronic diseases, patients can go to community health service centers, second-and third-class hospitals and other medical institutions through volunteers arranged by the village committee, or purchase medicines from retail pharmacies operating nearby. The city is rapidly promoting the resumption of retail pharmacies and publishing the list to the public according to the requirements of "all should be opened", and striving to release the drug supply service function of pharmacies in the community.

　　We also explicitly require that relevant medical institutions should optimize service processes and open up green channels, and provide long prescriptions for chronic patients with various diseases in general internal medicine, geriatrics, general medicine and other departments, or open simple dispensary clinics to serve the dispensing needs of citizens during the epidemic.

　　About the guarantee of supplyask

　　7. Shopping on the e-commerce platform now feels a little better, but it still can’t meet the needs of the citizens. How can we improve our operational capabilities next? The speed of offline supermarkets’ resumption of business is accelerating. How is the operation?

　　answer

　　For some time, the problem of online shopping has been prominent, mainly because many take-away riders have been blocked in the community, and a large number of e-commerce warehouses, supermarkets and logistics capacity have been temporarily closed due to epidemic prevention requirements, which makes it difficult for e-commerce to guarantee supply. The city strives to get through the blocking points and help the e-commerce platform to improve production capacity and transportation capacity on the premise of meeting epidemic prevention requirements.

　　The first is to restore operational capabilities. Commercial node outlets such as e-commerce warehouses and pre-warehouses should be fully opened. As of April 20, 51 e-commerce platforms in this city have resumed business, with a non-epidemic opening rate of 96.3%; 858 pre-warehouses resumed business, and the non-epidemic opening rate was 78.5%. There are 20,000 riders on the job.

　　The second is to strengthen the supply organization. Promote the e-commerce platform to expand the stocking volume and allocate goods across regions. In particular, with the coordination of the Yangtze River Delta Regional Cooperation Office and the strong support of Suzhou, Jiangsu and Jiaxing, Zhejiang, Kunshan Transit Station, Pinghu Transit Station and Shanghai-Kunming Traffic Mechanism have been established. By April 20th, the two transfer stations and the Shanghai-Kunming traffic mechanism had delivered 1,686 round trips, and transferred 14,700 tons of various living materials back to Shanghai.　

　　The third is to change the service model. Provide a service support system for collection, distribution and community group purchase. For example, Box Horse launched a mobile supermarket, which was delivered to the door of the community after consumers placed orders. The average daily order volume has exceeded 60,000, and a caring and helping team has been set up. The joint supplier sent 20 tons of materials to 15,000 elderly people over 75 years old who lived alone.

　　The city has made great efforts to promote the resumption of business of key stores such as supermarkets. By April 20th, 1079 key supermarket stores had opened online, among which 38 stores opened offline simultaneously. The number of employees on the job is about 10,000. Some supermarkets have launched a variety of family guarantee packages such as rice flour, grain and oil, vegetables and fruits, toiletries, etc., which are connected with street communities or collect community residents’ demand orders through enterprise apps, and then sorted and distributed by stores. Supermarket stores continue to expand supply, and by means of increasing transportation capacity and manpower, the efficiency of collection and distribution is continuously improved.

　　Increase cooperation with third-party logistics to improve transportation capacity. For example, Carrefour cooperated with Volkswagen Logistics, invested more than 50 minivans, served more than 500 communities, and the average daily order volume increased by four times compared with the previous period. This model has been replicated in Yonghui, CR Vanguard, Wal-Mart and other supermarket enterprises, and nearly 500 third-party logistics vehicles have been put into operation.

　　Increase the transfer of support from other provinces and cities to increase manpower. For example, RT Mart quickly organized stores in other provinces and cities to help Shanghai at the first time, and transferred more than 600 people to the key stores to be responsible for sorting, packaging and distributing the guaranteed materials. The average daily order volume increased by more than three times.

　　ask

　　8. After the implementation of the three-zone management, there are still a considerable number of citizens who cannot leave the community. What measures are taken to ensure the living materials?

　　answer

　　For the residents who can’t leave the community after the implementation of the three-zone management, there are mainly three aspects:

　　First, continue to focus on the market-oriented "collection and distribution, guaranteed supply package" approach. Connect with the community through supermarket stores and e-commerce platforms, collect residents’ ordering needs in a centralized way, and organize the supply of packages such as staple food and daily necessities. Supermarket stores cooperate with postal express and third-party logistics to enhance transportation capacity and ensure that living materials are delivered to the door of the community in time.

　　The second is to continue to distribute living materials gift packages to residents in various districts. Up to now, 16 districts in the city have completed two rounds of gift package distribution, and some districts are carrying out or preparing for new gift package distribution. The materials of the gift package basically cover vegetables, meat, rice flour oil and daily consumer goods. Some districts also distributed lunch boxes, instant noodles, biscuits, fruits, milk and other foods.

　　The third is to continue to strengthen the support for key areas and key populations. The city has established an emergency and supporting mechanism for the elderly living alone, double-aged families and other people with special needs to ensure the supply of their basic living materials. Promote the three-level hotline of city, district, street and town to improve the answering rate and strive to solve every appeal for help. Bailian Group and Guangming Group strengthened their cooperation with Shanghai Post, actively ensured the supply of living materials in key areas, especially in communities that have been closed for a long time, and started the service of helping the elderly. For example, Bailian Group docked with Sanlin Town, Pudong New Area, and as of April 20th, it had supplied 20,564 packages. Guangming Group uses the "96896" hotline of agriculture, industry and commerce to open a "bright through train" to connect the old people in need with the brand products of the group. Many social organizations and private enterprises carry out activities of caring for the elderly, many communities help each other in their neighborhoods, and the whole society makes joint efforts to consolidate the "floor" of urban security and supply.

　　ask

　　9. The rider is an important force to ensure supply. How to manage and serve the rider well?

　　answer

　　E-commerce platform riders are an important force in ensuring the supply of living materials in this city. Recently, various e-commerce platforms have actively organized qualified riders to return to their posts. The number of on-the-job riders has reached 20,000, and the daily delivery orders of major e-commerce platforms have reached 2.54 million.

　　The epidemic prevention management of riders is one of the topics of public concern. In order to ensure the health and safety of riders and the safety of delivery, the Municipal Commission of Commerce and the Municipal Postal Administration have established an e-commerce platform, a "white list" of express delivery companies and a "white list" of delivery and delivery personnel, and included enterprises with rider delivery business in the "white list" management. Up to now, more than 90 enterprises have been included in the "white list".Since April 19th, the dynamic "application code" has been adopted in the rider’s nucleic acid detection for identity verification and nucleic acid detection registration, replacing the offline nucleic acid detection code.Relying on the technical platform provided by the Municipal Big Data Center, the city will issue an "electronic pass" according to the "white list of enterprises" and "white list of personnel", and display the negative certificate of rider’s nucleic acid test and the green code of "health code" in the "electronic pass" as the necessary conditions and pass documents for the delivery and delivery personnel to take up their posts.

　　At the same time, in order to let riders feel the city temperature and provide good service to riders, the city is promoting the construction of "Little Brother Station". At present, 143 "Little Brother Stations" have been established in the city to provide services such as dining, rest and nucleic acid detection for courier brothers, and to implement various epidemic prevention requirements for courier brothers.

　　ask

　　10. The relevant departments indicated that they should intensify efforts to rectify the behavior of driving up prices and selling fake and inferior commodities. Why are there still commodities with abnormally high prices and poor quality on the market?　

　　answer

　　At present, a large number of "group buying" phenomena in Shanghai are the embodiment of market forces in a special period and a powerful supplement to the government’s guarantee of supply. At the same time, however, we also found that illegal acts such as price gouging, hoarding, shoddy goods and unclear price tag began to take hold, disrupting the market and harming the interests of citizens.

　　In this regard,Shanghai’s regulatory authorities are keeping a close eye on the prices of important people’s livelihood commodities and epidemic prevention supplies, focusing on "community group buying", e-commerce platforms, and supply-guarantee enterprises, and continuing to carry out price supervision and law enforcement., strictly and promptly investigate and deal with all kinds of price violations, and insist on investigating a batch, notifying a batch, warning a batch, and educating a batch.

　　Here, the market supervision department also advises consumers to pay attention to the selection of goods provided by regular suppliers when purchasing goods, and pay attention to keeping consumption records and screenshots of communication with relevant operators, so that they can be used as evidence when defending rights. We will deal with illegal acts strictly and promptly.

　　About nucleic acid code and big dataask

　　11. Some citizens reported that the nucleic acid test results were negative, but the disease control department called to inform them that they were positive. Who shall prevail?

　　answer

　　The information of nucleic acid test results inquired by the citizens in the "bidding with the bid" is uploaded by the testing institution. After the organization uploads the information, the "with the bid" will be displayed as soon as possible.Whether the information is accurate or not, and how the abnormal results are, shall be subject to the information of testing institutions and disease control departments.According to the unified requirements of the state, no positive results are displayed on the "bidding with the bid".

　　ask

　　12. Some positive cases did not live in this community, but the cases were listed in the community list at the time of publication. What caused this?

　　answer

　　For the determination of the address of the person whose nucleic acid test result is positive, the disease control department will make a comprehensive judgment based on the location information of the sampling point or the newly entered address information during nucleic acid sampling, and finally determine the address of the place where the positive person is located in combination with the on-site review of the sampling situation and the relevant information provided by the positive person during the flow adjustment.Persons with abnormal nucleic acid results of "household separation" will not be directly included in the address of the ID card.

　　Specifically, at present, the operation of the system mainly follows the following procedures: (1) Before each centralized sampling, volunteers will input the address of the nucleic acid sampling community in the mobile APP. The location information of sampling points in each community has been entered into the system as a whole before residents sample. (2) After entering the community address, the volunteers will scan the code to match the transfer boxes of nucleic acid collection samples, then scan the code to match the sample tubes in each box, and finally enter the citizen registration information. Therefore, the cell address, sample box, sample tube and the identity information of the sampled person are "bound" with each other and submitted to the system in a unified way. (3) Once the sample tube results are abnormal, the disease control personnel will find the transfer box of the sample through this information, and then read the address of the community where the sample is collected. Finally, the comprehensive big data is distributed to grass-roots units in all districts, and the personnel involved in mixed mining positive tubes are found for closed-loop disposal.

　　About resuming work and productionask

　　13. Shanghai issued the first list of enterprises that approved the resumption of production, but the citizens are worried that the effect of resuming production can be realized as soon as possible. Some people are also worried that the resumption of work and production now will bring hidden dangers of the spread of the epidemic.

　　answer

　　It is very important to coordinate the prevention and control of epidemic situation and the resumption of production for enterprises to win the battle of epidemic prevention and control. According to the deployment of "ensuring smooth logistics and promoting stable supply chain of industrial chain" and the requirements of the municipal party committee and municipal government, we promoted key enterprises with closed production conditions and epidemic prevention and control conditions to resume production in batches.As of April 20, 403 of the 666 enterprises under key monitoring were in production, accounting for more than 60%, which continued to increase for four consecutive days.

　　Focus on key industries and industrial chains with strong economic drive, strong epidemic prevention demonstration and closed-loop management conditions, increase coordination between ministries and cities, and promote chain-type resumption of work. On April 18th, SAIC and Tesla started to resume work and production simultaneously.On April 19th, more than 200 vehicles of SAIC passenger cars rolled off the assembly line, while Tesla rolled off the assembly line, and the output climbed steadily.The production capacity of 3M China has exceeded the level before the closure on April 1, and the total output of medical masks has exceeded 1 million since April.

　　Focus on important large enterprises to implement the "one enterprise, one plan" and emphasize the implementation of closed production management. Establish a working class mechanism to coordinate and solve problems such as raw material supply and inter-provincial logistics and transportation. Baoshan iron & steel, Shanghai Aircraft Manufacturing, Shanghai Petrochemical, Huahong Hongli, etc. continued to maintain high load operation. By promoting the resumption of production of key enterprises, the upstream and downstream of the industrial chain will be gradually driven to resume production.

　　In promoting the resumption of work and production, we should especially strengthen prevention and control measures. Strict prevention and control measures are responsible for enterprises, society and employees. We have fully absorbed the experience of closed production enterprises in preventing and controlling the epidemic since this month, and also learned from the good practices of brother provinces and cities to guide each enterprise to formulate the "one enterprise, one plan".Ensure that the production operation and epidemic prevention and control of enterprises are in a safe and controllable state..

　　ask

　　14. How do people who return to work apply to leave the community and return to their posts? What should I do if the community does not let people go?　

　　answer

　　At present, there have been some common and urgent problems in logistics and transportation, personnel returning to their posts, and industrial chain supporting. For example, for the return of personnel, some employees in key positions may be in the closed control area, and there are positive cases in the building. At present, the conditions for returning to work are not available, and enterprises should supplement other personnel to solve them.There are also some employees in key positions. Although they are in the closed control area, they meet the requirements that there are no positive cases in the building for 7 days and their nucleic acid is negative for 48 hours. The Municipal Economic and Information Committee has formulated measures to issue corresponding "electronic certificate" for employees of enterprises to assist them to enter the factory for closed management after point-to-point return.

　　At the same time, strengthen the nucleic acid detection of employees in enterprises that have resumed work and production. At present, according to the regional population density and functional orientation, Shanghai is planning and laying out a nucleic acid detection method combining "fixed sampling points+convenient sampling points+mobile sampling points" to coordinate the setting of normalized sampling points for the convenience of employees in parks and enterprises.

　　In the process of enterprises’ resumption of work and production, there may be problems in the industrial chain that the upstream and downstream are not smooth.Some chain owners can return to work, but spare parts supporting enterprises do not have the conditions, and these conditions of logistics and warehousing need to be gradually adapted. These problems require a lot of coordination work, and some need to find alternative solutions.

　　With the improvement of the epidemic situation, we will also make some institutional arrangements according to the problems found in enterprises’ resumption of work and production, especially under the guidance of the working group of relevant state departments in Shanghai and the support of brother provinces and cities. I believe that with everyone’s support, Shanghai’s industrial resumption of work and production will definitely move forward steadily.

　　About work improvementask

　　15. Some citizens have reported that some published policies have not been really implemented in some places or departments. What channels should citizens complain through and how will government departments supervise their implementation?

　　answer

　　The municipal party committee and the municipal government have always attached great importance to all kinds of problems in the implementation of the work. In this tough battle, party and government organs at all levels and leading cadres in party member must take a fighting stance, be strict in discipline, be tenacious in style and be effective in their work. The emergence of various problems, some of which are caused by limited grassroots strength and insufficient support, must be given practical support by the municipal and district departments to reduce the burden and increase the capacity of the grassroots; Some are caused by individual cadres’ lack of working ability and unrealistic style. In this regard, we are constantly improving our work.

　　A waste gas treatment tower was installed on the roof of the production workshop of Panyu Yuanmai Jewelry Co., Ltd., located in Daluotang Jewelry Zone, Panyu.

　　Keep the original heart, take the mission, find the gap and implement it

　　Carry out in-depth education on the theme of "Do not forget your initiative mind, Remember Mission"

　　There are more than 2,400 construction sites in Guangzhou, and dust from construction sites is one of the important causes of atmospheric particulate pollution, and it may be difficult to control dust pollution repeatedly. How to supervise it effectively for a long time is a difficult problem. At the same time, the general survey of pollution sources in Guangzhou has entered the stage of data summary and audit, which involves a wide range and a large amount of data. How to ensure the accuracy of the data is very important.

　　Therefore, in combination with the theme education of "Do not forget your initiative mind, keep in mind the mission", the Guangzhou Municipal Bureau of Ecology and Environment runs through the whole process of the theme education, implementing source control, standardizing the management of construction sites, implementing the pollution source survey, finding out what the problem is and where the crux lies, sticking to the word "reform" throughout, persisting in the establishment of reform, and resolutely fighting the tough battles of pollution prevention and pollution source survey.

　　Inspection and supervision: set up full-time environmental protection personnel to supervise the construction site.

　　The second phase of hengli town Resettlement Area in Nansha District is under intense construction. But different from people’s impression of dusty and disorderly, the construction site here is orderly: all the undeveloped land is covered with green dust-proof nets, and some land is afforested; Sprinklers are sprinkling water to reduce dust, and a 360-degree rotating spray head can be seen every 2.5 meters on the fence; The PM2.5 displayed on the screen of the 24-hour on-line dust detection system is about 25 μ g/m3. "Sprinklers will spray water regularly every two hours. spray head is basically open from 8 am to 6 pm, and fog cannons will also spray dust. In addition, the construction site is also equipped with 12 cleaning workers to clean the construction site and import and export roads. " The relevant person in charge of the project introduced.

　　In addition to consciously equipping the construction site with dust suppression facilities and implementing dust suppression measures, Jiezhen also has full-time environmentalists who use Guangzhou Dust APP to supervise the construction site. Liu Chunke, a full-time environmental protection worker in hengli town, told reporters that the dust on the construction site is inspected every week, including whether the engineering information is perfect, whether the transport vehicle is cleaned and whether the residual mud is covered. During the inspection, it is found that the land is not covered with green nets, the land that has not been constructed for a long time is not afforested, the construction road is not hard-bottomed, and the vehicles are not cleaned.

　　"In the process of routine inspection of the second phase project of hengli town resettlement area, it was found that there were problems of road dust emission and some exposed residual mud not covered." Liu Chunke said that he would take photos immediately after discovering the dust problem, and enter the problem into the Guangzhou Dust Supervision APP, and feed it back to the Nansha District Quality Supervision Station, the supervision unit of the construction site, and at the same time issue the Notice Letter on the Prevention and Control of Dust Pollution on the Construction Site to urge the construction unit to carry out rectification. After receiving the rectification notice, the construction unit immediately carried out rectification measures, arranged sprinklers to spray water immediately, and covered the exposed residual mud. "Now the awareness of dust pollution prevention and control in construction sites has also increased. Last year, the green net covering the land was in short supply, and the price has increased!"

　　On-line monitoring: the air quality was optimized obviously from January to July.

　　Dust is the main source of PM10 and PM2.5 in Guangzhou. In recent years, Guangzhou has vigorously promoted dust pollution control in construction sites, refined the "six hundred percent" requirements for dust pollution control, produced an atlas of guidance for green construction enclosure of construction projects, held on-site meetings, organized publicity training, promoted the installation of dust online monitoring equipment, strengthened law enforcement inspection, and increased notification and punishment. In view of the problem that dust pollution control in construction sites is easy to repeat and difficult to adhere to, since 2019, the regulatory authorities such as housing and construction have stepped up supervision, inspecting about 100 construction sites every day, urging the implementation of the "six hundred percent" requirements for dust pollution control, and at the same time using drones. Conduct inspections. Up to now, a total of 1080 online dust monitoring devices have been installed and networked.

　　In addition, in 2018, the municipal ecological and environmental department developed and launched the Dust Supervision APP, organized town and street environmental protection personnel to inspect the construction site, and reported the problems to the regulatory authorities in real time for follow-up. The users of the APP include the Municipal Housing and Urban-Rural Development Bureau, the Transportation Bureau, the Water Affairs Bureau, the Urban Management Comprehensive Law Enforcement Bureau, the Ecological Environment Bureau, the Forestry and Landscape Bureau, the Planning and Natural Resources Bureau, the Guangzhou Port Authority and the quality and safety supervision stations of various construction projects.

　　More than 2,400 construction sites in the city, regardless of the size, are all included in the Dust Supervision APP, which can be used to view and count the basic situation of construction projects. The supervision and inspection personnel of the ecological and environmental departments input the inspection and spot check information of the construction sites, and feed back the inspection and spot check information to the supervision units such as housing construction, water supply and transportation, and then the supervision units organize rectification and fill in the handling information, so as to implement the requirements of "establishing banks and reforming them" and form a multi-sectoral supervision mechanism for dust in Guangzhou. Since the beginning of this year, the city’s law enforcement officers have inspected 28,987 construction sites and 2,389 construction sites, and found that 1,304 "six hundred percent" problems have not been implemented, and all the problems found have been followed up and rectified.

　　The control effect of dust is also intuitively reflected in the air. From January to July 2019, the comprehensive index of ambient air in Guangzhou decreased by 13.4% year-on-year, and the air quality improved; The air quality reached the standard for 193 days, an increase of 25 days. Among them, the average concentration of PM2.5 was 28 μ g/m3, down 22.2% year-on-year; The average concentration of PM10 was 47 μ g/m3, down 14.5% year-on-year.

　　General survey of pollution sources: If you have any questions about filling in the form, you can ask the census taker.

　　The once-in-a-decade national pollution source survey has now entered the stage of data summary and audit, which is a major national survey, involving a wide range and a large amount of data. How to ensure the accuracy of the data is very important.

　　Guangzhou Panyu Yuanmai Jewelry Co., Ltd., located in Daluotang Jewelry Zone, Panyu, is a leading jewelry processing enterprise in Panyu District, mainly engaged in the processing of gold and silver jewelry and jewelry inlays. The relevant person in charge of the enterprise took out a checklist of dozens of pages and told the reporter: "Because there are differences in production technology and pollution control links, it is really unclear which links need to be filled in when filling out the form, how to fill them out, and some problems involving data unit conversion are also complicated. Fortunately, there are census takers and census instructors to help us fill out the form. "

　　According to the relevant person in charge of the Municipal Bureau of Ecology and Environment, the general survey of pollution sources is not as simple as expected. Sometimes a company has to visit several times. "For example, it is found that the company is closed at the scene, but it is uncertain whether the company is temporarily closed or seasonally closed. It takes a few more walks to be sure. " In addition, the general survey of pollution sources involves not only communication, but also technical problems in the form filling. Take shoemaking as an example, one of the two processes needs to be selected, that is, drawing wires and gluing. When filling in the form, some enterprises may mistake the gluing in the drawing wire process for the gluing process, resulting in wrong selection or multiple selection. Because the emission of pollutants is estimated by coefficient method, different processes correspond to different coefficients. If the previous process is not filled in correctly, the results estimated by coefficient method will be quite different. "In view of these situations, not only enumerators guide enterprises to fill in the forms, but also census instructors will further review the data. In addition, we will compare the data with the existing data to ensure the accuracy of the final data."

　　Pollution data: a map of pollution sources in the city will be drawn.

　　The national pollution source survey is a major national survey conducted by the State Council in accordance with the Regulations on the National Pollution Source Survey, which is conducted once every ten years. From 2007 to 2010, the first national pollution source survey was carried out, and this is the second national pollution source survey. The census time is arranged from 2017 to 2019, which is mainly divided into four stages: preliminary preparation, inventory building, household survey and summary release.

　　The relevant person in charge of the Municipal Bureau of Ecology and Environment said that in 2017, Guangzhou started the preparatory work for the general survey of pollution sources, and successfully completed the household survey task in 2018. At present, it has entered the stage of data summary review. After completing the data filling and entry system, Guangzhou was organized to carry out data auditing, on-site verification and data summary auditing in the household survey stage, and seriously carried out rectification and implementation according to the list of questions fed back by the national and provincial census offices.

　　In the stage of household survey, Guangzhou organized and carried out the work of reporting and auditing by enterprises, on-site auditing by census takers, on-site rechecking by census instructors, and conducted two rounds of data auditing for key information census forms, feedback from experts and auditing of census systems, to check input data and recheck spatial information.

　　Since January this year, two rounds of quality verification have been carried out, and industrial sources, large-scale livestock and poultry farms, centralized pollution control facilities, sewage outlets into rivers (seas), non-industrial source boilers, mobile sources, administrative villages and parks in 44 towns in 11 districts have been selected for on-site verification, and one census community in each district has been selected for pull-net verification.

　　After the census and accounting work, Guangzhou immediately transferred to the data summary and audit work. In June, the Municipal Census Office issued the Operational Guidelines for the Data Auditing of the Second National Pollution Source Census in Guangzhou, sent technical teams to all districts to guide the data summarization and auditing, and organized four rounds of data summarization and auditing successively.

　　From July to August, Guangzhou received a total of 16 issues of the list of suspected problems summarized and reviewed by the national and provincial census offices. The municipal census office immediately organized all districts to carry out verification work, seriously rectified the problem data, completed the systematic problem verification and rectification on time, and made notes on the verified problems one by one. In the next step, Guangzhou will continue to organize data summary and audit according to the requirements of the national and provincial census offices, so as to further improve the quality of census data and ensure compliance with relevant national requirements.

　　"The national pollution source survey is a major national survey once every ten years, and it is the basic work of environmental protection. It is of great significance for accurately judging the current environmental situation, formulating and implementing targeted policies and plans for economic and social development and environmental protection, and improving environmental quality." According to the relevant person in charge of the Municipal Bureau of Ecology and Environment, in the era of big data, the data of pollution source census is also used to make pollution source maps, and relevant management systems are developed, so as to accurately monitor the pollution sources in the city. "The map can show the distribution and types of enterprises in 11 districts of the city, and a management system is developed through the data of pollution source census, so as to accurately monitor the pollution sources in the city."

　　Guangzhou strengthens dust control supervision

　　Innovative supervision means

　　More than 2,400 construction sites in the city, regardless of the size, are all included in the dust supervision APP, which can be used to view and count the basic situation of construction projects;

　　Up to now, a total of 1080 online dust monitoring devices have been installed and networked in the city.

　　Carry out inspection and law enforcement

　　Since the beginning of this year, the city’s law enforcement officers have inspected 28,987 construction sites and 2,389 construction sites, and found that 1,304 "six hundred percent" problems have not been implemented, and all the problems found have been followed up and rectified.

　　Optimize air quality

　　From January to July 2019, the comprehensive index of ambient air in Guangzhou decreased by 13.4% year-on-year, and the air quality improved; The air quality reached the standard for 193 days, an increase of 25 days.

　　PM2.5 decreased by 22.2%

　　mean concentration

　　28 μ g/m3

　　PM10 decreased by 14.5%

　　mean concentration

　　47 μ g/m3

　　Grass-roots sound

　　Wu Shuchao, a villager from Nansha hengli town

　　There is less dust at home, so I can sleep well at night.

　　My home is opposite the construction site. In the past, the dust generated by the construction site, as well as the noise of vehicles entering and leaving, piling and so on, will have some impact on daily life. But now the construction site will sprinkle water regularly, and basically no dust will be felt at home, and the construction site will stop working at 9: 30 every night, so it is more stable to sleep at night.

　　Yuan Jianhui, a construction worker of Nansha hengli town Resettlement Area Phase II Project.

　　The workers all feel that the working environment is better.

　　Construction workers’ daily work, eating and rest are all on the construction site. Now there are not only sprinklers, spray head, fog guns and other dust suppression equipment on the construction site, but also cleaners to clean and control the dust well. The construction workers here feel that the working environment has improved, and the sprinkler operation can also play a certain role in cooling down!

　　Lin Weishen, Polluter of Pollution Sources in Panyu District

　　Only when the data is accurate can we do a good job of governance.

　　The accuracy of the basic data of pollution source census is very important, and about 500 enterprises have been visited since they entered the household last year. In the filling of the census form, a data unit and a decimal point need to be treated strictly. Only by ensuring the accuracy of the data can we truly reflect the production and discharge of pollution sources in enterprises, so as to supervise and control pollution in enterprises more pertinently.

　　It is even more essential to have a sense of responsibility and innovative thinking

　　In recent years, the air quality in Guangzhou is getting better and better. In the circle of friends, "Guangzhou Blue" often dominates the screen; In the streets and lanes, wherever you go, you bring your own "blue sky and white clouds" background. For two consecutive years, the concentration of PM2.5 has reached the standard, and such an eye-catching achievement cannot be separated from the strong promotion of dust control.

　　Construction site dust is one of the important causes of atmospheric particulate pollution, and there are problems that are easy to repeat and difficult to persist. For Guangzhou, the tight construction period and large number of projects under construction also make it more difficult to control dust pollution. However, there are always more ways than difficulties, and the key depends on whether the understanding is in place and whether the action is firm. This means that on the one hand, it is necessary to raise awareness, further enhance supervision consciousness, put the control of dust pollution in a prominent position, and achieve results. On the other hand, we should also innovate methods, make full use of new technologies and means, optimize processes and improve efficiency. For example, launch the dust supervision APP, organize town and street environmentalists to inspect the construction site, and report problems to the regulatory authorities in real time for follow-up; Promote the installation of dust online monitoring equipment and strengthen law enforcement inspection; Using drones to carry out inspections and improve supervision efficiency & HELIP; …

　　Driven by a series of measures, the effect of dust supervision is "immediate". From January to July this year, Guangzhou’s air quality reached the standard for 193 days, an increase of 25 days year-on-year, and the concentration of atmospheric particulate matter related to dust showed a downward trend. The feelings of citizens are also intuitive. Many people say that the dust generated by the previous construction site, as well as the noise of vehicles entering and leaving, piling and so on, are annoying. At present, the construction site will be watered regularly, and the work will be finished on time when it arrives. The faster the building is built, the less and less impact it will have on life. It is understood that under the supervision of the regulatory authorities, many construction sites are equipped with sprinklers, spray head, fog guns and other dust suppression equipment. For managing dust pollution, everyone’s initiative and consciousness are constantly improving.

　　In the final analysis, it is necessary to turn knowledge into action and goals into reality. It can be seen from the dust control that how to do a good job and achieve results requires a sense of responsibility and innovative thinking.
