沈阳市人为源大气污染物排放清单研究

Emission inventory of anthropogenic air pollutant sources in Shenyang

为全面评估沈阳市大气污染物排放状况,文章收集和整理了相关活动水平信息和排放因子数据并采用排放因子法建立了2016年沈阳市人为源大气污染物排放清单。结果显示:2016年沈阳市人为源CO、NO_(x)、SO_(2)、NH_(3)、VOCs、PM_(2.5)、PM_(10)、BC和OC的排放总量分别为38.64×10^(4)、10.63×10^(4)、3.17×10^(4)、5.28×10^(4)、14.03×10^(4)、5.54×10^(4)、10.59×10^(4)、0.57×10^(4)和1.82×10^(4)t。按照排放源分类,CO、NO_(x)和BC主要来自移动源,SO_(2)主要来自化石燃料固定燃烧源,NH_(3)主要来自农业源,VOCs主要来自工艺过程源,PM_(2.5)和PM_(10)主要来自扬尘源,OC主要来自其他排放源。按照排放源区县分类,NO_(x)、SO_(2)、VOCs、PM_(2.5)、PM_(10)和BC主要来自铁西区,CO、OC主要来自新民市,NH_(3)主要来自辽中区。

In order to comprehensively evaluate the emission status of anthropogenic air pollutants in Shenyang,the activity data and emission factors were collected,and the emission factor method was used to establish the emission inventory of anthropogenic air pollutant sources in Shenyang in 2016.The results showed that the total emissions of CO,NO_(x),SO_(2),NH_(3),VOCs,PM_(2.5),PM_(10),BC and OC in Shenyang were 38.64×10^(4)、10.63×10^(4)、3.17×10^(4)、5.28×10^(4)、14.03×10^(4)、5.54×10^(4)、10.59×10^(4)、0.57×10^(4)and 1.82×10^(4)t in 2016,respectively.According to the classification of emission sources,CO,NO_(x)and BC were mainly from the mobile source,and SO_(2)was mainly from the stationary combustion source.NH_(3)was mainly from the agricultural source,and VOCs was mainly from the industrial process source.PM25 and PM_(10)were mainly from the fugitive dust source,and OC was mainly from the other emission sources.According to the classification of districts,NO_(x),SO_(2),VOCs,PM_(2.5),PM_(10)and BC were mainly distributed in Tiexi District.CO and OC were mainly distributed in Xinmin City,and NH_(3)was mainly distributed in Liaozhong District.
