| 摘 要： | 水中的有机污染物由于其毒性、持久性和生物难降解性,对生态环境和人体健康造成严重危害。传统膜分离技术通过物理截留去除水中污染物,然而有机污染物、微生物与膜表面的相互作用不可避免地导致膜污染,缩短膜使用寿命。电化学膜分离技术(electrochemical membrane filtration,EMF)是一种集污染物截留和电化学降解双重功能于一体的新兴水处理技术,具有强化污染物去除、抗污染和效能提升的优势,因此在污染物深度脱除和消毒等方面得到了广泛研究与关注。介绍了电化学膜分离技术在水处理中的研究进展,简述了其工作原理和优势,并重点分析了电化学膜材料、反应器运行参数、水质条件的影响,介绍了该技术在污染物去除和水体消毒的应用现状,最后对其发展进行了总结和展望。

| Abstract: | Organic contaminants in water/wastewater could cause damage to the ecosystem and human health due to their toxicity, persistence and bio-refractory nature. The membrane-based separation processes separate contaminants from water by physicochemical mechanisms. However, the interactions of organic molecules, and microorganisms with membrane surfaces inevitably lead to membrane fouling, which shortens membrane lifetime. Electrochemical membrane filtration (EMF) is an emerging water treatment technology that integrates the dual functions of contaminant retention and electrochemical degradation. It has the advantages of enhanced contaminant removal, antifouling and improved performance, which has received extensive research attention in the areas of advanced contaminant removal and disinfection. This paper reviews the research progress of electrochemical membrane filtration for water treatment in recent years, and introduces the principles of operation and advantages. The electrochemical membrane materials, reactor operating parameters, the influence of water quality parameters and the applications of EMF in pollutant removal and water disinfection are also summarized. Finally, the future development and perspectives of EMF are proposed. |
