摘要
大气污染物排放清单是了解区域污染物排放特征的重要资料,而工业源是大气污染的重点排放源,本研究基于二污普收集汇总的污染源基础信息,运用污普的排污系数,计算新会区主要大气污染物的排放量,建立了2017年工业大气污染源排放清单。结果表明,新会区2017年排放二氧化硫2341.540 t,氮氧化物4436.160 t,颗粒物9224.670 t,挥发性有机物14563.098 t,重金属275.469 kg。燃煤锅炉和炉窑是SO2、NOX和重金属的最大排放贡献源,其他污染物主要来源于工业生产过程,其中颗粒物排放的主要贡献行业为非金属矿物制品业和金属制品业,挥发性有机物排放的主要贡献行业为金属制品业、计算机、通信和其他电子设备制造业、印刷和记录媒介复制业和黑色金属冶炼和压延加工业。双水镇、罗坑镇、大鳌镇、会城街道与崖门镇为大气污染物的主要贡献乡镇。
Developing of atmospheric pollutant emission inventories is important for understanding regional emission characteristic. The spot emission sources of industries are the major sources of at-mospheric pollution. Based on the Collection of aggregated source information of The Second Na-tional Pollution Source Survey, the inventory of industrial atmospheric pollutant emission for 2017 was developed by using an appropriate estimation method and emission factors. The result showed that the total industrial emissions of SO2, NOx, Particles, VOCS, Heavy metals in Xinhui in 2017 were 2341.540 t, 4436.160 t, 9224.670 t, 14563.098 t, 275.469 kg. Coal-fired boilers and furnaces are the largest sources of emissions of SO2, NOX and heavy metals, and other pollutants are mainly derived from industrial production processes. The main contribution industries of particulate matter emissions are non-metallic mineral products and metal products, while the main contribution industries of VOCS emissions are metal products, computer and communications and other electronic equipment manufacturing, printing and recording media reproduction and ferrous metal smelting and calender processing. Shuangshui Town, Luokeng Town, Daao Town, Huicheng Street and Yamen Town are the main contribution towns of air pollutants.
