Taiyuan's comprehensive air pollution index has historically entered the "4.0+" era
The reporter recently learned from the Taiyuan Municipal Bureau of Ecology and Environment that in 2023, the comprehensive air pollution index of Taiyuan urban area will be 4.95, a year-on-year decrease of 2.8%, and it will historically enter the "4.0+" era, which is the best result since the monitoring history in 2013.
The Taiyuan Municipal Party Committee and Municipal Government attach great importance to the prevention and control of air pollution, firmly shoulder the political responsibility of improving the ecological environment, focus on outstanding problems such as heavy pollution weather, ozone and dust pollution, and take a multi-pronged approach to pollution control, coal control, vehicle management and dust reduction, and strengthen atmospheric environment governance in an all-round, full-chain and all-weather manner. In 2023, three of the six pollutant concentrations decreased year-on-year compared with 2022, namely: sulfur dioxide concentration was 11 micrograms per cubic meter, a decrease of 8.3%; PM2.5the concentration was 41 micrograms/cubic meter, down 6.8%; PM10The concentration was 78 micrograms per cubic meter, a decrease of 6.0%. One pollutant, nitrogen dioxide (40 micrograms per cubic meter), remained unchanged year-on-year. Two pollutants increased year-on-year: carbon monoxide concentration was 1.5 mg/m3, up 7.1%, and ozone concentration was 178 μg/m3, up 1.7%.
In terms of industrial pollution control, last year, Taiyuan City closed down the 600,000 tons/year production capacity of Xishan Coal Gasification Coke in Gujiao City, and coke ovens of 5.5 meters and below completely withdrew from the historical stage; the relocation of Dongshan limestone mine and pyrotechnic area entered the stage of step-by-step implementation; China Shipping Energy completed the transformation of unorganized emission control; 6 cement enterprises completed ultra-low emission transformation and acceptance monitoring, 2 foundry enterprises completed the transformation of cupola furnaces into electric furnaces and put them into operation; steadily promoted the transformation of 3 coking enterprises in Qingxu with standby dry quenching coke, the treatment of TISCO slag yards, and the "public to iron" conversion in Qingxu and other key projects, and implement a number of projects such as SUS Energy, Huanjin Energy, and in-depth treatment of nitrogen oxides in domestic waste incineration power plants.
In view of the frequent occurrence of ozone and heavy pollution weather in autumn and winter, Taiyuan City carried out the summer ozone peak shaving action, completed the Meijin coking volatile organic compounds treatment project, replaced the volatile organic compounds in 197 industrial enterprises, and cleaned 4,614 catering and barbecue restaurants, and implemented the "daily dispatch" mechanism during the "autumn and winter prevention" period to accurately guide the pollution control of the city's industrial sources, mobile sources, dust sources and coal-fired sources, and strictly implement the provincial "1+30" Through the regional joint prevention and control mechanism, 2,090 enterprises have implemented graded emission reduction measures for environmental performance.
to lower PM10In order to tackle the key direction, Taiyuan City has carried out differentiated control of ABC performance grading at construction sites to effectively curb the adverse effects of various types of dust on air quality. More than 51,500 construction sites were inspected throughout the year, more than 11.27 million square meters of construction sites were supervised, more than 610,000 square meters of site hardening were supervised, a total of 346 construction sites were interviewed, 2,736 dust problems were found and rectified at construction sites, 510 correction notices were issued, and 74 dust hazard buildings were punished.
In addition, Taiyuan has comprehensively deepened the synergy of pollution reduction and carbon reduction, further promoted the construction of national climate investment and financing pilots, organized and carried out carbon monitoring and evaluation pilots, completed carbon equipment joint commissioning and data stability testing, and all high-precision points have begun to be formally monitored. The Wusu zero-carbon airport project has become the first batch of near-zero carbon emission pilot demonstration projects in Shanxi Province.
