摘要
为控制大气SO2 污染 ,各国科技人员先后开发了 2 0 0多种烟气脱硫技术 ,比较常用的有石灰石 石膏法、催化氧化法、吸附法等。综合考虑经济和技术问题 ,比较适合我国的方法有 :石灰作吸收剂的SDA系统、托普索湿法硫酸工艺、活性炭 磷铵法等。SDA脱硫渣可与磷石膏一起制水泥和硫酸。各企业应因地制宜 ,选用技术先进、经济合理、操作简单、可有效控制污染的脱硫工艺。
Over two hundred flue gas desulphurization methods had been developed in the world.Among them,line-plaster stone,catalytic oxidati on and adsportion method were in common use.Enterprises shloud chose suitable me thods,which were advanced,ecnomical and effective to controll the pollution,acco rding to their own situation.
