摘要基于环境统计数据,采用排放因子法建立2020年京津冀地区燃煤工业锅炉县级大气污染物排放清单.结果表明,2020年京津冀地区燃煤工业锅炉常规大气污染物SO₂、NO_x、颗粒物(PM)、PM₁₀、PM_2.5排放量分别为6351,7399,2952,825,399t.,其中PM₁₀和PM_2.5分别占PM排放总量的27.9%和13.5%.重金属Hg、Pb、Cd、Cr、As的排放量分别为197.9,1391.3,32.0,1214.2,362.4kg.65t/h及以上燃煤工业锅炉为主要的排放贡献源,各类污染物的排放量占京津冀地区工业锅炉各类污染物排放总量的比重为51.1%~81.2%,是污染控制及监管的重点.河北省承德市、唐山市、张家口市为污染物排放量最大的3个城市,3个城市各类污染物排放量占京津冀地区工业锅炉各类污染物排放总量的14.6%~71.9%.污染物排放强度大的区域主要集中在天津市、河北省廊坊市、唐山市的一些区县.

Abstract：Based on environmental statistics data, a sophisticated county-based emission inventory on multiple air pollutants from coal-fired industrial boilers (CFIBs) in Beijing-Tianjin-Hebei (BTH) region in 2020 was established by using the emission factor method. Results showed that the emission of SO₂, NO_x, particulate matter (PM), PM₁₀, PM_2.5 from CFIBs in BTH region were about 6351, 7399, 2952, 825, 399t, respectively, of which the emission of PM₁₀ and PM_2.5 accounted for 27.9% and 13.5% of the PM emission. The trace metal emissions of Hg, Pb, Cd, Cr and As were 197.9, 1391.3, 32.0, 1214.2, 362.4kg, respectively. CFIBs with the capacity above 65t/h was the dominant emission sources, and their emission of various pollutants accounted for 51.1% to 81.2% of the total emissions in BTH region, which would be the focus of pollution control and compliance management in the future. Chengde, Tangshan and Zhangjiakou were the top three cities with the largest pollutant emissions with their combined emission accounting for 14.6%~71.9% of the total emissions in the whole BTH region. Some counties within Tianjin, Langfang and Tangshan had relatively high pollutants emission intensities.
