摘要
为研究西宁市非金属矿物制品业对大气污染物的贡献情况,根据排放因子方法建立了西宁市2018年非金属矿物制品业4种大气污染物的排放清单,并对清单进行了时空分布及不确定性分析,为西宁市非金属矿物制品业污染物排放控制提供依据.结果显示,西宁市2018年非金属矿物制品业大气污染物NO_(x)、SO_(2)、PM_(2.5)和PM_(10)的排放总量分别为3300.18、1195.93、1281.18和2382.72 t.西宁市非金属矿物制品业污染物排放企业主要在大通县、湟中县、城北区,集中在西宁市南部.其中,大通县是NO_(x)和SO_(2)最大的贡献区域,也是PM_(2.5)和PM_(10)的第二大贡献区域;湟中县是PM_(2.5)和PM_(10)的最大贡献区域,也是NO_(x)和SO_(2)的第二大贡献区域.水泥(干法)行业是NO_(x)、SO_(2)、PM_(2.5)和PM_(10)主要的排放源,其各污染物排放量占非金属矿物制品业各污染物总排放量的比例分别为97.02%、72.42%、35.05%和35.53%.蒙特卡罗法模拟结果表明,在95%置信区间下水泥(干法)行业的SO_(2)排放不确定度最高,砖瓦及建筑砌块行业的SO_(2)排放不确定度最低.
In order to study the contribution of Xining’s non-metallic mineral products industry to air pollutants,according to the emission factor method,an emission inventory of air pollutants from the nonmetallic mineral products industry for 2018 in Xining City was established,and the temporal and spatial distribution and uncertainty of the inventory was analyzed.It provides a basis for the pollutant emission control of the non-metallic mineral products industry in Xining City.The results show that:In 2018,the total emissions of atmospheric pollutants NO_(x),SO_(2),PM_(2.5)and PM_(10)from the non-metallic mineral products industry in Xining City were 3300.18,1195.93,1281.18 and 2382.72 t,respectively.Pollutant emission companies in the non-metallic mineral products industry of Xining City are mainly concentrated in Datong County,Huangzhong County,Chengbei District,which locate mainly in the south of Xining City.Datong County is the largest contribution area of NO_(x) and SO_(2),and also the second largest contribution area of PM_(2.5)and PM_(10).Huangzhong County is the largest contribution area of PM_(2.5)and PM_(10),and the second largest contribution area of NO_(x)and SO_(2).The cement(dry process)industry is the main emission source of NO_(x),SO_(2),PM_(2.5)and PM_(10),its pollutant emissions accounted for 97.02%,72.42%,35.05%and35.53%of the total pollutant emissions of the non-metallic mineral products industry,respectively.Monte Carlo simulation results show that under the 95%confidence interval,the highest SO_(2) emission uncertainty is from the cement(dry process)industry,and the lowest SO_(2) emission uncertainty is from the brick and building block industry.
