摘要
基于工业企业填报以及天水市生态环境局等相关单位提供的数据,利用排放因子法建立了天水市2019年人为源VOCs排放清单。结果表明2019年天水市人为源VOCs排放总量为8028.27 t;道路移动源、化石燃料燃烧源、生物质燃烧源、溶剂使用源、工艺过程源、非道路移动源排放量分别占排放总量的31.22%、21.99%、16.58%、13.4%、12.51%、4.31%,其中摩托车和民用散煤燃烧分别为道路移动源和化石燃料燃烧源的主要排放来源,占其排放量的56.31%、87.24%。各县区中,麦积区、秦州区和甘谷县的排放量较大,分别占天水市人为源VOCs总排放量的19.22%、17.72%、17.68%。
Based on the data reported by industrial enterprises and provided by Tianshui Ecological and Environmental Bureau and other relevant units,the inventory of the anthropogenic VOCs emission of Tianshui in 2019 was developed via using emission factor method.The results showed that the total anthropogenic emission amount of VOCs in Tianshui was 8028.27t in 2019,of which 31.22%,21.99%,16.58%,13.4%,12.51%,4.31%respectively resulted from the mobile sources,the burning of fossil fuels,biomass combustion sources,solvent using source,technology source,the non-road mobile source,and motorcycle and civil coal combustion are two major secondary emission sources,respectively accounted for 56.31%and 87.24%of the mobile sources and the burning of fossil fuels.Among the counties and districts,Maiji District,Qinzhou District and Gangu County have larger emissions,accounting for 19.22%,17.72%,and 17.68%of the total emissions of anthropogenic VOCs in Tianshui City,respectively.
