呼和浩特市工业料堆扬尘排放清单研究

Fugitive Dust Emission of Storage Pile Inventory in Urban Hohhot

颗粒物污染是影响中国城市空气质量的首要因素。工业料堆扬尘是城市大气颗粒物污染的主要来源之一。本文通过对呼和浩特市建成区内典型行业风蚀、作业及交通运输扬尘进行采样分析,应用美国AP-42提供的模型,以2006年作为基准年,建立了呼和浩特市工业料堆排放清单。研究结果表明:呼和浩特市建成区内工业料堆扬尘排放量为TSP:5 305 t/a,PM10:1 012 t/a,PM2.5:267 t/a。从空间分布看玉泉区工业料堆扬尘排放量最大,其次是赛罕区。行业分布上排放最大的行业是建材工业,其次是电力热力工业,最少的是化工工业。在各行业类别的工业料堆排放量中,交通运输扬尘排放量是最大的。

Particulate pollution caused by fugitive dusts from storage pile is one of the primary pollutant sources which influence China’s urban air quality in recent years.In this study,industrial wind erosion,aggregate storage pile dust and typical transportation dust were sampled.AP-42 emission factor was used to calculate the emission of storage pile fugitive dust in urban Hohhot in 2006.The results show that industrial dust emissions from urban Hohhot piles are TSP 5 305 t/a,PM101012t/a and PM2.5267t/a.From the perspective of space distribution,Yuquan District is polluted most seriously and Saihan District is the second.From the industry distribution,building materials industry has the highest emission,followed by electric power and heat industry,chemical industry emits the least.Transport industry has the highest emission.
