【摘要】：扩展的德亚盖因-兰多-弗韦-奥弗比克理论(The extended Derjaguin-Landau-VerweyOverbeek,XDLVO)可以用于定量解析界面之间的相互作用性质及程度,因而有助于理解膜法水处理过程中复杂的膜污染现象并提供膜污染问题的预防或解决思路.考察了近年来在相关方面理论解析膜与污染物相互作用的界面相互作用能的文献报道和研究进展,利用已有参数基于XDLVO理论进行计算和数据统计分析,总结出了不同膜材料和不同污染物在进行膜法水处理过程中容易发生膜污染的可能顺序,并调查了膜分离过程中溶液条件对膜污染的影响.进一步提出目前研究中存在的问题,并对XDLVO理论在膜污染问题解析方面的研究进行了展望.
[Abstract]:The extended Derjaguin-Landau-Verwey Overbeek XDLVO) can be used to quantitatively analyze the properties and extent of interaction between interfaces. Therefore, it is helpful to understand the complex membrane fouling phenomenon in the process of membrane water treatment and to provide the prevention or solution of membrane fouling problem. The recent literature reports and research progress on the interaction energy between membrane and contaminant are reviewed. The existing parameters are used to calculate and analyze the data based on XDLVO theory. The possible sequence of membrane fouling in the process of membrane water treatment with different membrane materials and pollutants was summarized and the effects of solution conditions on membrane fouling during membrane separation were investigated. The existing problems in the current research are put forward, and the research of XDLVO theory in the analysis of membrane fouling is prospected.
