摘要:

燃煤烟气汞污染近些年来被世界公认为又一大污染问题,本文较为详细地论述了汞排放控制技术现状及研究进展。目前有多种在研的汞控制技术,其中湿法洗涤和烟气中喷入活性炭吸附剂方式等较有发展潜力,但现在还没有一种适用性强的技术可广泛推广。最后介绍了烟气脱汞的一些新技术,并对脱汞技术的发展前景进行了展望。

Abstract:

Mercury pollution in coal-fired flue gas is thought to be another big pollution problem. The research progress of mercury emission control is summarized. Currently many strategies for mercury control are being investigatedand wet scrubbers and dry injection of a sorbentsuch as activated carbon into the flue gas are the most promising technologies. But there is still no single best technology that can be broadly applied. Several new mercury control technologies are introduced and their application prospects are discussed.
