Guide: The reporter learned from the Harbin Ecological Environment Bureau that in order to speed up the control of air pollution in winter, effectively improve air quality

　　The reporter learned from the Harbin Ecological Environment Bureau that in order to speed up the winter air pollution control and effectively improve air quality, Harbin recently formulated the "Harbin City Winter Air Pollution Control Implementation Plan (2020-2022)." The "Plan" proposes that by the heating period of 2022-2023, coal consumption in key areas will drop significantly, replacing 2.6 million tons of coal; the number of heavily polluted days will be reduced by 40% compared with the heating period of 2019-2020, reaching less than 16 days.

　　The "Plan" requires that, focusing on rural areas, urban villages, and shanty towns, coal-fired alternatives "one policy", coal-fired facilities and heat source transformation "two-handed", greatly reduce the total emissions of air pollutants, and significantly improve air quality , The environmental, economic and social benefits have been significantly improved. During the heating period from 2022 to 2023, coal consumption in key areas will drop significantly, replacing 2.6 million tons of coal; the average concentration of fine particulate matter (PM2.5) in the three heating periods will reach 30%, 50% and 20% of the air quality improvement target. %, no more than 68 micrograms/cubic meter, 55 micrograms/cubic meter and 50 micrograms/cubic meter; the number of heavily polluted days will be reduced by 40% compared with the heating period of 2019-2020, reaching less than 16 days, avoiding the daily average value of air quality index "explosive" table".

　　At the same time, the local area will continue to expand the scope of boiler elimination, highlight the elimination of coal-fired boilers in key areas, especially core areas, and achieve within 3 years the urban built-up area (core area) below 35 steam tons and the county (city) Chengguan town built-up area 10 steam tons and The following coal-fired boilers are "cleared", 35 (inclusive) to 65 steam tons are subject to special emission limits, and the implementation of "coal to gas" heating boilers is included in urban peak shaving. Eliminate 702 coal-fired boilers in key areas, replacing 197,300 tons of coal. It is planned to complete 142 ultra-low emission transformations of coal-fired power plants and coal-fired boilers of 65 steam tons and above in 9 districts in the city in three years.
