Guide: This year, our province held a meeting to promote the "three-fold and one reform" tackling action for bulk coal pollution control, and identified Harbin City, Suihua City, Zhaozhou County, Zhaoyuan County, Yabuli Ski Resort and Xuexiang as the bulk coal pollution control. "Key Regions". At the press conference on the results of the "Hundred Days Battle" in Heilongjiang Province’s pollution prevention and control battle held on the 1st, Zhao Xuewen, director of the Atmospheric Environment Division of the Provincial Department of Ecology and Environment, introduced how our province will deal with heavy pollution in winter, especially for "soot" Pollution measures.

　　This year, our province held a meeting to promote the "three-fold and one reform" tackling action for bulk coal pollution control, and identified Harbin City, Suihua City, Zhaozhou County, Zhaoyuan County, Yabuli Ski Resort, and Xuexiang tourist attractions as bulk coal pollution control "Key Regions". At the press conference on the results of the "Hundred Days Battle" of the Heilongjiang Province Pollution Prevention and Control Battle held on the 1st, Zhao Xuewen, Director of the Atmospheric Environment Division of the Provincial Department of Ecology and Environment, introduced how our province will deal with heavy pollution in winter, especially for "soot". Pollution measures.

　　Zhao Xuewen introduced that in recent years, our province’s air pollution prevention and control work has achieved certain results, but seasonal and regional air pollution problems have not yet been fundamentally resolved, especially in shanty towns, urban villages, and urban-rural areas in Harbin and Suihua. The use of loose coal and the combustion of loose coal do not have any pollution control measures. The PM2.5 emissions per unit of coal combustion are more than 15 times that of power plants, which is serious. According to statistical analysis, the province's total coal consumption in winter is 74.76 million tons and pollutant emissions are 758,100 tons. Among them, the total consumption of bulk coal is 9.56 million tons, accounting for 12.8% of the total, but the pollutant emissions are 432,800 tons, accounting for 57.1% of the total, which means that the bulk coal accounts for 1/8 of the total coal. It contributes nearly 60% of the emissions of coal-burning pollutants and has become one of the important factors affecting air quality.

　　In order to focus on solving the problem of loose coal pollution, on August 7 this year, the General Office of the Provincial Government issued the "Implementation Plan for the "Triple and One Reform" Tackling Actions for the Pollution Control of Loose Coal in Heilongjiang Province (2020-2022)". The overall idea of ​​“cleaning coal and controlling coal” took three years to highlight the “two cities, two counties and two scenic spots”, namely Harbin City, Suihua City, Zhaozhou County, Zhaoyuan County, Yabuli Ski Resort, Snow Pollution control of scattered coal in key areas such as township tourist attractions. Adhere to the goal orientation and focus on solving the problem of winter air pollution. It is clear that by the heating period of 2022-2023, the average PM2.5 concentration of Harbin and Suihua will drop from the highest values ​​of 76 and 64 micrograms/m3 in the past three years to no more than 50 micrograms. /Cubic meter, the annual average value is expected to reach the standard; the number of heavy pollution days will be reduced by 40%, and they will be controlled within 16 days and 14 days respectively.

　　In terms of engineering measures, it highlights the "reduction" of loose coal, the "dismantling" of boilers, the "cleanness" of emissions, and the "warm" in winter. Vigorously reduce the amount of bulk coal, and arrange five bulk coal pollution control tasks in shanty towns, urban villages, urban-rural junctions, merchants, and rural areas. Harbin and Suihua cities will cut 88,900 tons of bulk coal in shanty towns, and use straw-solidified fuel to replace rural areas The scattered coal in the area was 154,100 tons. Speed ​​up the demolition and phase-out of coal-fired boilers, arrange for the elimination of coal-fired boilers with less than 10 steam tons, 10-35 steam-ton coal-fired boilers, and upgrade and transform 35-65-steam-ton coal-fired boilers. Harbin and Suihua will completely eliminate 10 steam per hour Coal-fired boilers of ton and below, coal-fired boilers supplying heating with less than 35 steam tons per hour in urban built-up areas are "cleared", and coal-fired boilers with 35-65 steam tons per hour meet the special emission limit requirements of air pollutants. Comprehensively improve the level of ultra-low emissions, arrange three tasks including key heat sources and ultra-low emissions from large coal-burning households, ultra-low emissions from power companies, and optimizing the layout of clean energy. 92 coal-fired boilers of 65 steam tons per hour and above in Harbin urban built-up area The ultra-low emission transformation was completed, and the ultra-low emission transformation task of coal power generating units in the urban built-up areas of Harbin and Suihua was "cleared." Focus on optimizing the heating structure, and arrange six tasks including central heating, smart heating, clean heating, biomass cogeneration, building energy-saving renovation, and old pipe network renovation. Harbin and Suihua have added 19.7 million central heating areas Square meters, the newly added biomass cogeneration installed capacity is 935,000 kilowatts, the energy-saving renovation of existing residential buildings is 21,393,400 square meters, and the old pipe network is 650.5 kilometers.

　　In the next step, the Provincial Department of Ecology and Environment will work with the development and reform, housing construction, agriculture and rural departments to implement responsibilities, improve mechanisms, coordination, focus on contradictions, and dare to take responsibility, so as to effectively improve environmental air quality.
