南京市生物质燃烧源大气污染物排放清单及其特征

Emission Inventories of Atmospheric Pollutants Discharged from Biomass Burning in Nanjing City

该研究根据搜集的南京市生物质燃烧源活动水平数据,采用排放因子法,建立了南京市2015年生物质燃烧源大气污染物排放清单。结果表明:(1)2015年南京市生物质燃烧源主要大气污染物SO_2、NO_X、PM_(10)、PM_(2.5)、BC、OC、CO、VOC_S、NH_3排放量分别为553t、1504t、3123t、2920t、501t、1793t、27653t、3396t和446t;(2)生物质燃烧大气污染物排放地区分布不均衡,排放量较大的是六合、溧水、江宁、高淳区;(3)各类生物质燃烧对不同污染物排放量的贡献差异显著。生物质锅炉是SO_2和NO_X排放的主要来源,户用炉灶是PM_(10)、PM_(2.5)、BC、OC、CO、VOC_S、NH_3的主要贡献源。

Based on the activity data collected from biomass burning source in Nanjing, emission inventory was devel- oped and its characteristics were analyzed.Results showed that the totat emissions of SO2. NOx. PM10. PM25. BC.OC, CO, VOCs. NH3 were estimated to be 553t. 1504t, 3123t. 2920t, 501 t, 1793t, 27653t, 3396t and 446t.Uneven alloca- tion of air pollutants discharged from each district was observed, with larger emissions from Luhe, Lishui, Jiangning, Gaochun.The contribution to the amount of pollutants discharged from each kind of biomass burning differed greatly, in which biomass boiler was the main source of SO2 and NOx emissions, while household stoves was the main source of PM10, PM25, BC, OC, CO, VOCs, NH3 emissions.
