重金属废水处理最新进展

重金属废水处理最新进展专论与综述重金属废水处理最新进展张永锋,许振良(华东理工大学化学工程研究所,上海200237)[摘要]详细论述了近年来一些处理重金属废水的新方法,并对各种方法进行了综合评述。这些新方法主要有:廉价吸附剂吸附、胶束增强超滤、络合-超滤耦合过程和电化学法。此外,将络合-超滤和电化学法集成起来处理重金属废水,可实现废水回用和重金属回收,因而具有广阔的应用前景。[关键词]重金属废水;廉价吸附剂;胶束增强超滤;络合-超滤耦合过程;电化学[中图分类号]X703.1[文献标识码]A[文章编号]1005-829X(2003)06-0001-05LatestdevelopmentsofthetreatmentofheavymetalwastewaterZhangYongfeng,XuZhenliang(ChemicalEngineeringResearchCentre,EastChinaUniversityofScienceandTechnology,Shanghai200237,China)Abstract:Thenewmethodsofthetreatmentofheavymetalwastewaterinrecentyearsarediscussedindetail.Thesenewmethodsmainlyincludetheabsorptionoflow2costsorbents,micellar2enhancedultrafiltration,complexation-ultrafiltra2tioncouplingprocessandelectrochemicalmethod.Besides,thehybridprocessofcomplexation-ultrafiltrationcombiningwithelectrochemicalmethodforheavymetalwastewatertreatmentcouldbeusedforthewastewaterreuseandtherecoveryoftheheavymetalsinthenearfuture.Keywords:heavymetalwastewater;low2costsorbents;micellar2enhancedultrafiltration;complexation-
