摘要
膜分离过程中存在的膜污染问题严重制约了膜分离技术的大规模应用。扩展的XDLVO(Derjaguin-Landau-Verwey-Overbeek)理论可以为膜污染机理的阐述提供理论支撑,它不仅可以用来解析及预测膜污染,还可为膜污染控制提供理论指导。介绍了XDLVO理论的分析计算方法,综述了XDLVO理论在不同污染物的膜污染行为解析中的应用,讨论了膜面性质及操作条件对膜污染行为的影响以及XDLVO理论对膜污染控制的指导作用,并提出了XDLVO理论在膜污染行为研究中存在的问题以及对未来研究方向的展望。
The problem of membrane fouling in the membrane separation process has severely restricted the largescale application of membrane separation technology.The mechanisms of membrane fouling can be described by the extended Derjaguin-Landau-Verwey-Overbeek(XDLVO)theory,which can be used to analyze and predict membrane fouling,and provide guidance for membrane fouling control.Firstly,the descriptions of XDLVO theory were elaborated.Secondly,the applications of XDLVO theory in the analysis of membrane fouling behavior with different foulants were reviewed.Thirdly,the influence of membrane surface properties and operating conditions on membrane fouling and the guiding function for membrane fouling control were discussed.Finally,the problems of the application ofXDLVO theoryinthestudiesofmembranefoulingandprospectsoffutureresearchdirectionwereputforward.
