This text describes the pollution state of SO2 of our country at first, point out the inferior fire coal is a main reason for pollution, before analyzing and comparing with firing at present on this basis, fire and daily SO 2 polluted the pluses and minuses of the control technology after firing, think because of our country fundamental realities of the country, control present SO2 pollution effectively, should little fine coal be law's desulphurization technology have priority development fire.关键词 二氧化硫 污染 控制技术Key words sulfur dioxide pollution control technique中图分类号 文献标志能源、经济、环境、可持续发展是人类面临的紧迫课题。煤炭提供了我国 75%的工业燃料,76% 的发电能源和 80%的民用商品能源[1] ,在我国一次能源消费结构中占有最主要的地位。但是煤炭在生产和加工利用过程的同时也造成了严重的环境污染,其中由于燃煤排放 SO2而引发的“酸雨”污染近年来愈演愈烈,已经严重影响到我国全面建设小康社会目标的顺利实现。1 燃煤 SO2污染现状二氧化硫的主要污染源可归纳为三个方面:(1)硫酸厂和汽车尾气中排放的二氧化硫;(2)有色金属冶炼过程排放的二氧化硫...
