Application of Lon Exchange Technology in Heavy Metals Wastewater Treatment

Lei Zhaowu,Sun Ying(Department of Environmental Engineering,Environmental Management College of China,Qinhuangdao 066004,China)  
Heavy metal wastewater must be treated because the wastewater containing heavy metal ions harmed to human being and environment.The method of chemical precipitation was widely applied to treating the wastewater,but the mass sludge heavy metal produced with the method needed to be disposed properly.The wastewater was treated by ion exchange technology,heavy metal ions could be removed and could be recovered,and avoided much sediment from wastewater treated by chemic-Sedimentation.Heavy metals could be better removed and recovered to use selective removal of heavy metal ions from wastewater by ion exchange.
