鄂州市高时空分辨率大气污染源排放清单的建立

Establishment of High Resolution Atmospheric Emission Inventory in Ezhou City

为进一步推进鄂州市大气污染防治工作,加强大气环境质量及重污染应急工作保障,文章基于污染源普查成果建立了2017年鄂州市高时空分辨率大气污染源排放清单。研究通过对鄂州市固定燃烧源、工艺过程源、溶剂使用源等的调查,借助第二次全国污染源普查成果,获得污染源的基本信息。鄂州市2017年各类大气污染物排放情况:SO2为8048.58 t、NOx为18363.60 t、CO为306258.10 t、VOCs为19146.60 t、NH3为2603.01 t、PM10为22695.50 t、PM_(2.5)为10811.73 t、BC为918.34 t、OC为1018.93 t。工艺过程源对SO2、NOx、CO、VOCs、PM_(10)、PM_(2.5)的贡献率最大,分别为66.75%、63.41%、89.87%、68.28%、54.69%、66.51%;农业源对NH3的贡献率最大,为53.71%;固定燃烧源对BC、OC的贡献率最大,分别为35.85%、37.85%。

Based on the survey of pollution sources,the 2017 high-resolution atmospheric emission inventory for Ezhou City,Hubei was established,which further promoted the prevention and control of air pollution in the City,and strengthened the protection of atmospheric environmental quality and heavy pollution emergency.This research investigated the stationary combustion source,process source,solvent sources,etc,based on the results of the Second National Pollution Source Survey.The City’s emissions in 2017 of SO2,NOx,CO,VOCs,NH3,PM10,PM2.5,BC and OC were 8048.58,18363.60,306258.10,19146.60,2603.01,22695.50,10811.73,918.34,and 1018.93 tons,respectively.Process sources had the most contribution rates to SO2,NOx,CO,VOCs,PM10,PM2.5,accounting for 66.75%,63.41%,89.87%,68.28%,54.69%and 66.51%individually.Agricultural sources had the largest contribution rate(53.71%)to NH3.The contribution rates of fixed combustion sources to BC and OC were the largest,accounting for 35.85%and 37.85%respectively.
