摘要

为研究京津冀地区民用散煤燃烧大气污染物的排放情况，结合散煤燃烧活动水平与燃用特征，根据排放因子法自下而上建立了2018年京津冀地区民用散煤燃烧污染物排放清单，研究了污染物排放的时空分布特征并使用蒙特卡罗方法对排放清单进行了不确定性分析.结果表明：2018年京津冀地区民用散煤燃烧量共计3799.22万t，PM_2.5、CO、SO₂、NO_x的排放量分别为9.27，341.31，5.17，5.44万t.污染物排放集中在11月份~次年3月份，大多数地区呈现出相同的日排放趋势.8：00、11：00、18：00、21：00左右出现污染物排放峰值，小时排放系数平均值分别为11%，6%，7%，13%.PM_2.5排放高值区主要集中在北部、东部及部分南部地区，CO主要集中在北京和天津地区，SO₂和NO_x主要集中在天津和承德地区.

Abstract

In order to study the emission of atmospheric pollutants from residential coal combustion in BTH region, combined with the level of residential coal combustion activity and combustion characteristics, the emission inventory of pollutants from residential coal combustion in BTH region in 2018 was established from bottom to up according to the emission factor method. The temporal and spatial distribution characteristics of pollutant emissions were studied and the uncertainty analysis of the emission inventory was carried out by using the Monte Carlo method. The results showed that the total amount of residential coal in BTH region in 2018 was 3799.22 million tons, and the emissions of PM_2.5, CO, SO₂ and NO_x were 9.27×10⁴, 341.31×10⁴, 5.17×10⁴ and 5.44×10⁴ tons, respectively. Pollutant emissions were concentrated in November to March of the following year, and most areas showed the same daily emission trend. The peak emission of pollutants appeared at 8:00, 11:00, 18:00 and 21:00, with the average hourly emission coefficients were 11%, 6%, 7% and 13%, respectively. The high values of PM_2.5 emission were mainly concentrated in the northern, eastern and part of southern regions. CO was mainly concentrated in Beijing and Tianjin, while SO₂ and NO_x were mainly concentrated in Tianjin and Chengde.
