安徽省非金属矿物制品业大气污染物分布特点

Distribution characteristics of atmospheric pollutants of non-metallic mineral products industry in Anhui

以安徽省第二次全国污染源普查数据为依据,分析非金属矿物制品业SO_(2)、NO_(x)、颗粒物排放的空间及类型分布特点。结果表明:(1)从空间分布来看,SO_(2)排放量前3位的城市分别为淮南市、阜阳市、合肥市,其贡献率分别为20.1%、9.1%、7.8%;NO_(x)排放量前3位的城市分别为芜湖市、铜陵市、宣城市,其贡献率分别为16.4%、14.8%、11.4%;颗粒物排放量前3位的城市分别为宿州市、合肥市、淮南市,其贡献率分别为17.6%、17.2%、10.9%。(2)从类型分布来看,砖瓦、石材等建筑材料制造业的SO_(2)排放量和排放强度,水泥及水泥制品业的NO_(x)、颗粒物排放量和排放强度均最大。

The spatial and type distribution characteristics of SO_(2),NO_(x)and particulates of non-metallic mineral products industry were analyzed according to the data of second national pollution sources survey of Anhui.Results showed that:(1)in terms of spatial distribution,Huainan,Fuyang and Hefei were the top three cities of SO_(2)emission,with contribution rates of 20.1%,9.1%and 7.8%respectively.Wuhu,Tongling and Xuancheng were the top three cities of NO_(x)emission,with contribution rates of 16.4%,14.8%and 11.4%respectively.Suzhou,Hefei and Huainan were the top three cities of particulates emission,with contribution rates of 17.6%,17.2%and 10.9%respectively.(2)In terms of type distribution,the SO_(2)emission and emission intensity of brick,stone and other building materials manufacturing industry,and the NO_(x)and particulates emission and emission intensity of cement and cement products industry were the largest.
