China News Service, May 18, according to the official Weibo news of the Beijing Municipal Bureau of Ecology and Environment, the Beijing Municipal Bureau of Ecology and Environment pointed out on the 18th that the air quality situation in Beijing will generally improve in 2020. As of the end of April, the concentrations of the four major air pollutants have all reached historical best, of which the cumulative concentration of fine particulate matter (PM2.5) was 47 micrograms / cubic meter, a year-on-year decrease of 7.8%. The cumulative number of good days was 99 days, an increase of 15 days year-on-year, and the ratio of good days exceeded 80% for the first time. The average concentration of PM2.5 in April was 31 micrograms per cubic meter, a year-on-year decrease of 35.4%, the lowest in the same period in history.

According to the Beijing Municipal Bureau of Ecology and Environment, in April, while coordinating the normalization of epidemic prevention and control and economic and social development, it continued to deepen the "one microgram" action on air pollution prevention and control, focusing on key areas such as diesel trucks, dust and volatile organic compounds. , Continue to work hard and make precise efforts to promote the implementation of various measures in the 2020 action plan to win the Blue Sky Defence War.
One is to control pollution in accordance with the law and tackle pollution from mobile sources. Focusing on the implementation of regulations on the prevention and control of emissions from motor vehicles and non-road mobile machinery (hereinafter referred to as the "Regulations"), the Standing Committee of the Beijing, Tianjin and Hebei People's Congress jointly held a press conference to expand the influence of the "Regulations"; Supporting documents such as terminal installation management methods, non-road mobile machinery registration management methods, motor vehicle emission inspection management regulations and other supporting documents ensure the effective implementation of the Regulations and improve the closed-loop management mechanism. Promote the standardized management of non-road mobile machinery registration and filing, strengthen the precise supervision of "one machine and one code", and accumulatively passed 29,000 units. Further clarify the work flow of the application process for the award and renewal of high-emission obsolete motor vehicles, and promote the smooth implementation of the country III gasoline vehicle phase-out and renewal work. Continue to promote the "transit rail" of freight transportation. This year, a total of 410,000 tons of sand and gravel materials were imported into Beijing, and nearly 14,000 commercial vehicles were sent; the first green sand and stone construction base was established, and the "distance transportation within the trunk railway city + new energy heavy truck" was adopted. "End connection" transportation mode, to improve the green level of construction gravel aggregate production and transportation.
The second is technology pollution control, consolidating the effectiveness of fine dust control. The Municipal Eco-Environmental Bureau piloted the implementation of dust load monitoring on roads within 100 meters on both sides of the industrial site entrances and exits in the six districts of the city, and strictly controlled the export of dust. The Municipal Transportation Commission increased the investment in cleaning and cleaning, and raised the standards for cleaning and cleaning of the first-class routes in the built-up area. The Municipal Agricultural and Rural Bureau plans to implement straw mulching to return farmland and no-tillage planting to 207,000 mu of agricultural land. The Municipal Landscaping Bureau strictly controls dust control in spring afforestation projects.
From January to April, the urban management law enforcement department investigated and dealt with 5,344 illegal acts of construction dust and fined 14.22 million yuan. In accordance with the actual situation of the jurisdiction, each district has innovated and refined the management of dust. Among them, Dongcheng and Xicheng combined with the "Patriotic Health Monthly Cleaning" activity to conduct a comprehensive roof cleaning; Haidian District piloted the construction site closed construction; Daxing District promoted 67,000 acres of bare land greening; Huairou District installed inhalable particulate matter in key engineering earthwork sites in real time Monitor equipment and track pollution emissions.
The third is to focus on key points and implement special actions for volatile organic compounds. Eliminate and withdraw 36 general manufacturing and polluting enterprises; print and issue "Volatile Organic Compounds Management Work Guide" to guide the in-depth management and fine management of volatile organic compounds "one plant and one policy"; 2 rounds of leak detection and repair. Focus on townships (streets) with lower air quality rankings and outstanding problems, and carry out "acupuncture" law enforcement. From January to April, the eco-environmental department filed 535 penalties for environmental violations by industrial enterprises, and 52 major cases were implemented.
