In the first half of this year, our district implemented the "one micrograms" operation and strengthened the coordination and treatment of PM2.5 and ozone. Various departments and streets and towns closely focused on the "Action Plan for the In -depth Pollution Prevention and Control of the Haidian District". Twenty key tasks in 6 major tasks in 6 major fields in 6 major fields in 6 major fields in 6 major areas, such as nitrogen oxide emission reduction, volatile organic matter, urban refinement management, regional joint prevention joint control, and improvement of governance system capabilities, have achieved positive results. From January to June, the air quality of Haidian District continued to improve, and the average PM2.5 concentration decreased by 26.2%year -on -year, and the air quality maintained the best city in the six districts of the city.

Be a "environmental housekeeper" of government enterprises

Baiwang Green Valley Auto Repair Park is located on Malianwa Street and covers an area of ​​180 acres. There are 15 types of auto repair units in the park. The high density of the industry has gathered. High -monthly. In this regard, the District Ecological and Environment Bureau took multiple measures and cited practical tricks to accurately assist the problems and strive to be a good government and enterprise "environmental protection steward".

"The Haidian District Ecological and Environment Bureau has organized environmental protection training for its prone to and existing problems in the industry, as well as related professional knowledge. In order to further reduce the exhaust emissions and combine the training content, we deliberately upgraded the operating facilities in the store to upgrade and transformation . "Li Xu, director of the after -sale service of Huanyu Hengtong.

Li Xu and the reporter came to the hazardous waste room after the store. He pointed to a device similar to an air -conditioning outside the outer wall of the hazardous waste room and introduced to the reporter, "The taste here was particularly nasal, and in the District Ecological Environment Bureau Under the guidance, we installed the exhaust gas purification facilities, which benefited a lot. "According to assistance guidance, in addition to the hazardous waste room, the store has been upgraded to the lacquer room, polishing room, etc. model.

It is understood that in order to enhance the awareness of environmental protection and strengthen the responsibility of the enterprise, the District Ecological Environment Bureau regularly organizes enterprises to carry out centralized training, comprehensively announces laws, regulations and industry standards, and combines the characteristics of the auto repair industry. Status, from high -frequency prone problems to specific case examples, through detailed data, typical cases, and specific harm interpretation. Yu Xinshen introduced by the District Ecological and Environment Bureau's comprehensive law enforcement brigade: "We use the methods of promoting education and on -site assistance to the promotion of the original auxiliary materials of low volatile organic matter content to the operation. Specific guidance has been conducted to effectively improve the company's self -examination and self -correction in environmental protection. From links to details, more 'Haidian Blue' is deducted by one micrograms and one micrograms. "

In order to formulate a practical and feasible rectification plan, the District Ecological and Environment Bureau scientific research and judgment, the pulse inquiries determine the good recipe, and use the "one -certificate" management method to make a good sewage permit and combine the results of the local inspection. Carry out comprehensive arranging, sorting out problems, and establishing accounts.

It also invited industry experts and testing agencies to start from the perspective of the industry, based on the entire process of material selection, operation management and pollution prevention, to benefit and discuss good strategies.

Combined with the needs of air pollution prevention and control in autumn and winter, the District Ecological Environment Bureau has carried out special full -time law enforcement to complete the full -time supervision of enterprises in the park. Pay close attention to environmental data, conduct joint law enforcement from time to time, comprehensive law enforcement brigade, and monitoring stations, strengthen law enforcement monitoring and linkage, timely regulate illegal links, severely crack down on illegal acts, strengthen corporate awareness of compliance with the law, and eliminate illegal luck.

The Haidian District has made its best to improve the air quality. There are more and more blue sky and white clouds. The pollution of smog and dust has decreased year by year. The continuous improvement of air quality is obvious to the masses.

In addition to the average PM2.5 concentration decreased year -on -year, the concentrations of the four major pollutants in Haidian District in the first half of the year were the best in history. Among them, the average concentration of fine particles (PM2.5) was 31 micrograms/cubic meter, a year -on -year decrease of 26.2%. The average concentration of inhalation of particulate matter (PM10), sulfur dioxide (SO2), and nitric oxide (NO2) was 54 micrograms/cubic meter, respectively. , 2 micrograms/cubic meters, 27 micrograms/cubic meters, decreased by 18.2%, 33.3%, and 18.2%year -on -year, respectively. The excellent days were 143 days, an increase of 18 days year -on -year, and the number of excellent days accounted for 78.5%.
