水泥行业非常规污染物的研究进展
RESEARCH PROGRESS OF NONCONVENTIONAL POLLUTANT IN CEMENT INDUSTRY
-
摘要: 水泥行业不仅大量排放颗粒物、二氧化硫、氮氧化物等常规污染物,也是重金属、多环芳烃、二恶英等非常规大气污染物的排放源。随着水泥窑危险废物协同处置技术的推广,可能引起的非常规污染物更加引起国内外的广泛关注。总结了水泥行业非常规污染物的来源与危害,并对国内外水泥行业非常规污染物的排放标准、研究现状及控制技术进行了综述,最后对其研究方向进行了展望。Abstract: Cement industry is not only the emission source of normal pollutants including PM,NOx ,SO2 ,but also the nonconventional pollutants,like heavy metals,PCB,amd dioxin. The emission of the nonconventional pollutants is being extensively concerned when the fuel used in a cement kiln was partially replaced by dangerous wastes. Researches on sources and harm of nonconventional pollutants in cement industry are reviewed. The national standards,the emission status and controlling technologies in China and abroad are investigated. In addition,the future research directions are proposed.
