印刷电路板废水处理技术及其进展

环境工程2010年第28卷增刊印刷电路板废水处理技术及其进展宋倩杨秋红吕航但德忠(四川大学建筑与环境学院,成都610065)摘要:印刷电路板废水不同于普通化工废水,由于水量大、水质复杂导致在实际工程中出现处理难度大、处理成本高的困难,是限制电子工业元器件发展的主要因素之一。针对我国印刷电路板废水污染日益严重的现状,结合此类废水的来源、水质特征及生化特性,概述了印刷电路板废水处理常用的物理法、化学法和生物法,及其应用现状和发展方向,并指出膜处理技术将成为今后印刷电路板废水处理的主要方法。关键词:印刷电路板;废水;水处理技术TREATMENTTECHNOLOGYANDITSDEVELOPMENTOFPRINTEDCIRCUITBOARDWASTEWATERSongQianYangQiuhongL™HangDanDezhong(InstituteofArchitectureandEnvironment,SichuanUniversity,Chengdu610065,China)Abstract:Printedcircuitboardwastewaterisbadlydeleterioustoenvironment,anddifficulttotreatbecauseofitsparticularqualitydifferentfromcommonchemicalengineeringwastewater1Aimedattheincreasinglypollu-tionstatusofprintedcircuitboardwastewaterinChina,thesourcesandchemicalandbiochemicalcharactersofprintedcircuitboardwastewateraswellasvarioustreatmentandcontrollingtechnologiesforprintedcircuitboardwastewatersuchasphysical,chemicalandbiologicaltreatmentmethodsarereviewed1Thepresentap-plicationstatusanddevelopmenttrendsandofthesetechniquesareanalyzedandevaluated
