摘要 以京津冀及周边地区水泥工业为研究对象,基于产排污系数法,建立了水泥工业主要大气污染物排放计算方法,对2016年该地区水泥工业主要大气污染物排放控制水平进行了分析.结果表明:京津冀及周边地区2016年水泥工业SO_2、NO_x、PM(有组织)排放量分别达到3.2?10~4t、23.9?10~4t、9.7?10~4t,较2015年分别减少24.1%、18.2%、27.2%,各项污染物大幅下降.水泥工业PM无组织排放量占PM总排放量的45.4%,仍需要采取集中收集的方式加强治理.山东、河南是水泥工业SO_2、NO_x、PM、PM_(10)、PM_(2.5)重点排放来源,应通过化解过剩产能降低污染排放.从各工艺来看,新型干法工艺应考虑采用高效脱氮脱硫技术、协同处置技术、高效大型袋式除尘技术等新技术,进一步降低各项污染物的排放量;粉磨站也需进一步提高污染治理水平. A model for estimating air pollutant emissions from cement industry was developed based on emission factors for the greater Beijing-Tianjin-Hebei region.The estimated emissions based on the model were used to analyze of current status and emission characteristics of the major air pollutants,including SO2,NOx,and PM from cement industry in 2016.The results showed that the emissions of SO2,NOx and nonfugitive PM from cement industry were 3.2×104t、23.9×104t、9.7×104t,24.1%,18.2%,27.2%less than which in 2015,respectively.Fugitive PM contributes to 45.4%of the total PM emissions,and it is necessary to enhance colleting the fugitive PM emissions.Shandong and Henan are the greater contributor of SO2,NOx,PM,PM10 and PM2.5 emissions from cement industry.More phasing out of abundant cement producing capacity in these two provinces should be a key measure to reduce their emissions.The cutting-edge technologies such as high efficiency nitrogen and sulfur removal technology,collaborative disposal technology and high efficiency baghouse filter should be considered reduce the emissions from the New Dry Process clinker production,and the pollution control in the grinding stations also need to be strengthened.
