Fenton_混凝沉淀法预处理锂电池加工高浓度废水_管锡珺Fenton—混凝沉淀法预处理锂电池加工高浓度废水管锡珺，仇模凯，夏丽佳，张明辉，陈修硕，刘晓茹，唐振（青岛理工大学环境与市政工程学院，山东青岛266033）［摘要］采用Fenton—混凝沉淀法处理锂电池盖板冲洗废水，研究其最佳反应条件，并探讨各因素的影响机理。结果表明：室温条件下，在Fenton反应阶段，30%H2O2投加量为12.5mL/L、FeSO4·7H2O投加量为4.0g/L、pH为2.5、反应时间为1h时，COD去除率可达91.81%；Fenton反应出水用PAC混凝沉淀法进行再处理，pH为中性或偏碱性、PAC投加量为80mg/L条件下，最终出水COD去除率可达93.9%。［关键词］Fenton试剂；混凝；沉淀；锂电池加工废水［中图分类号］X703［文献标识码］A［文章编号］1005-829X（2018）12-0076-05Pretreatmentofhigh-concentrationlithiumbatteryprocessingwastewaterbyFenton-coagulationprecipitationmethodGuanXijun，QiuMokai，XiaLijia，ZhangMinghui，ChenXiushuo，LiuXiaoru，TangZhen（SchoolofEnvironmentalandMunicipalEngineering，QingdaoUniversityofTechnology，Qingdao266033，China）Abstract：Fenton-coagulationprecipitationmethodhasbeenusedfortreatingthewastewaterfromlithiumbatterycover-boardrinsing.TheoptimalreactionconditionsofCODremovalbyFenton-coagulationprecipitationmethodhavebeeninvestigated，andthentheinfluencemechanismsoffactorsdiscussed.TheresultsshowthattheremovalrateofCODis91.81%，atroomtemperat
