News from this newspaper (Reporter Wang Bin) A reporter from Beijing Youth Daily learned from the Municipal Ecological Environment Bureau that as of the end of July, the average concentration of fine particulate matter (PM2.5) in the air in Beijing was 29 micrograms per cubic meter, a year-on-year decrease of 21.6%, and continued to create a new record. It was the best in the same period in history, with the lowest concentration and the largest drop among the "2+26" cities in Beijing-Tianjin-Hebei and surrounding areas.
The concentrations of inhalable particulate matter (PM10), nitrogen dioxide and sulfur dioxide were 53 μg/m3, 21 μg/m3 and 3 μg/m3, respectively, down 14.5%, 16% and the same year-on-year, all of which were the best in history for the same period. Level.
Since the beginning of the summer, Beijing has used nitrogen oxides (NOx) and volatile organic compounds (VOCs) as a breakthrough to strengthen the coordinated control of PM2.5 and ozone, continue to promote green and low-carbon transformation and high-quality development, and promote the "one microgram" action. in depth.
The relevant person in charge of the Municipal Bureau of Ecology and Environment introduced that the city has strengthened source control, accelerated the revision of air pollutant emission standards for the printing and automobile manufacturing industries, and further tightened VOCs content limits and management requirements.
At the same time, carry out end-of-line management, continue to promote the upgrading and transformation of 56 key industry enterprises "one factory, one policy", and evaluate and publicize the clean production audit work of the first batch of 37 units in 2022.
Strengthen process management, complete two rounds of navigation monitoring of VOCs concentration in 34 key industrial parks and agglomeration areas in the city, and establish a closed-loop supervision mechanism of "monitoring - notification - traceability, rectification and improvement".
The city also actively promotes the renewal and demonstration of new energy vehicles. Daxing District has promoted a total of 309 hydrogen energy vehicles, and Yanqing District uses hydrogen energy buses that participate in the Beijing Winter Olympics guarantee services to carry out public transport operations.
Changping District and Haidian District respectively carried out the demonstration operation of hydrogen energy vehicles.
Accelerate the transformation of clean energy, and accelerate the transformation of oil-fired boilers in Dongcheng District and Xicheng District.
Mentougou, Fangshan, Huairou, Miyun, Yanqing and other districts, orderly promote the conversion of coal to clean energy and the construction of supporting power infrastructure in villages.
In addition, the city has implemented precise law enforcement, and Beijing has launched the second round of municipal-level "point-pointing" law enforcement actions, constantly improving the "monitoring-supervision-supervision" linkage mechanism, and strengthening the application of scientific and technological means.
During the operation, a total of 188 enterprises and sites of various types were inspected, and 120 environmental problems were found; the night-time law enforcement inspection of heavy-duty diesel vehicles entering Beijing and key roads in the city was strengthened, and a total of 182,000 vehicles were tested and 3,086 vehicles were punished for exceeding the standard.
At the same time, we strengthened legal assistance and carried out law popularization during law enforcement; included 309 law-abiding companies in the "positive list", and carried out off-site law enforcement; clarified three categories of 31 non-punishment situations, and sanctioned more than 200 eligible companies in accordance with the law. Supervise rectification and provide assistance and guidance.
Help enterprises to upgrade green, according to the management idea of classification and classification, take the initiative to visit the door, carry out on-site investigations on enterprises in key industries such as automobile manufacturing, cement, industrial coating, etc., provide technology and services for enterprises, help enterprises solve problems, technical transformation and upgrading, and achieve green high-quality development.
In the next step, Beijing will continue to strengthen the emission reduction of volatile organic compounds (VOCs), nitrogen oxides and other common precursors of PM2.5 and ozone, and promote the continuous improvement of air quality throughout the year.
