摘　　要：通过分析UNEP发布的《全球汞评估报告》,总结了国内外水泥工业汞排放现状,对比了全球主要水泥生产国的汞排放系数,研究了燃煤对水泥工业汞排放的重要影响。2015年全球水泥工业汞排放总量为277t,我国水泥工业汞排放总量为134.05t。结合水泥工业特点,分析了汞减排技术及效率,提出了我国水泥工业汞减排的最佳途径。Based on the analysis of the Global Mercury Assessment released by UNEP,the present situation of mercury emission in cement industry at home and abroad was summarized.The mercury emission factor of cement in major production countries was compared and the important influence of coal combustion on mercury emission from cement industry was studied.The total mercury emission of global cement industry is 277t and the total mercury emission of cement industry in China is 134.05t in 2015.Combined with the characteristics of cement industry,mercury emission control measures and efficiency are analyzed and the best way to reduce mercury emission in China's cement industry is proposed.
