摘　　要：根据煤的赋存形式和逸散特性,把重金属分为不挥发痕量元素、中等挥发痕量元素、易挥发痕量元素,并对其控制方式及脱除方法进行对比,同时也讨论了颗粒物与气态重金属控制设备。痕量重金属的排放控制是近年来较为重要的环保课题之一,对其进行高效吸附及在线监测控制以及对重金属及其他污染实施综合控制具有很大的研究空间。According to the occurrence form and dissipation characteristics of coal,heavy metals are divided into non-volatile trace elements,medium volatile trace elements,and volatile trace elements,and the relating control and removal methods are compared.Control equipment for particulate matters and gaseous heavy metal is also discussed.Emission control of trace heavy metals is one of more important environmental issues in recent years.There is a lot of research spaces in efficient adsorption,and online monitoring and control of heavy metals as well as implementing comprehensive control on heavy metals and other pollutants.
