广安市大气污染源排放清单研究

Research on Air Pollutant Emission Inventory in Guang’an

基于全面的实地调研,获取了广安市2016年各典型污染源的活动水平数据,以城市大气污染物排放清单编制技术手册为指导,采用排放因子法,建立了广安市2016年大气污染源排放清单,并分析了主要污染源排放特征。结果表明,2016年广安市SO2、NOX、CO、PM10、PM2.5、VOCs、NH3总排放量分别为31706t、28084t、115874t、56415t、19710t、24774t以及39484t。SO2排放主要来自工业源;NOX排放主要来自工业源和移动源;CO排放主要来自工业源、民用燃烧源及移动源;PM10和PM2.5排放来自工业源、扬尘源和露天秸秆焚烧;VOCs主要来自工业源、移动源以及溶剂使用源;NH3主要来自农业排放。

In this study, activity level data of typical pollution sources in Guang an in 2016 were obtained through a comprehensive field-research. Based on the technical manual of establishment of urban air pollutant emission inventory, the emission inventory of Guang an in 2016 was set up by emission factor method, and the emission characteristics of main pollution sources were analyzed. The results showed that the total emission of SO 2, NO X, CO, PM 10 , PM 2.5 , VOCs and NH 3 in Guang an in 2016 were 31706 t, 28084 t, 115874 t, 56415 t, 19710 t, 24774 t, and 39484 t, respectively. Industrial source was the main contribution of SO 2. NO X mainly come from industrial source and mobile source. Industrial, domestic combustion and mobile source were the chief sources of CO. The main emission of Primary PM 10 and PM 2.5 come from industrial source, dust and incineration of open-air straw. VOCs mainly come from industrial, mobile sources and solvent-use. Agricultural emission was the largest source of NH 3.
