中文摘要:
      通过调研2018年四川省37条水泥生产线活动水平数据,结合企业污染治理技术,分析该省水泥工业的主要大气污染物排放水平。结果表明:2018年四川省水泥〖JP2〗行业SO2、NOx、PM25和PM10的排放量分别为12万t、55万t、39万t〖JP〗和65万t,其不确定性主要来自污染物的产生系数和去除效率。四川省水泥生产企业各工序排放的颗粒物、SO2和NOx浓度总体上均低于现行标准,部分工序颗粒物超标主要受布袋的去除效率影响。
英文摘要:
      By investigating the activity level of 37 cement production lines in Sichuan province in 2018, and the pollution control technologies, the emission level of the major atmospheric pollutants in the cement industry was analyzed. The results showed that the emissions of SO2,NOx,PM2.5 and PM10  were 12 000 t, 55 000 t, 39 000 t and 65 000 t in 2018 in Sichuan cement industry, respectively, the uncertainty were mainly from the production coefficient and the removal efficiency of the pollutants. The emission concentration of particulate matter, SO2 and NOx were below the current standards in each process of cement production. Particulate matter which exceeded the standard in some processes was mainly affected by the removal efficiency of bag filter.
