摘要
有机废水中难降解有机物控制不当,将严重影响生态环境和人类健康。有机废水深度处理技术的开发已成为水处理领域的研究热点。催化氧化-膜分离技术作为一种可同时兼具物理分离与化学氧化于一体的深度净水技术备受关注。催化膜耦合高级氧化技术(AOPs)不仅可以通过提高氧化性能促进污染物去除,还能通过强化自由基生成抑制膜污染,实现“自清洁”。文中结合国内外最新研究进展,全面总结了催化膜的制备方法,并重点讨论其与光催化、Fenton氧化、过硫酸盐活化、臭氧氧化及电催化氧化过程耦合的性能与机制。同时,针对催化膜耦合氧化过程的影响因素、优势及其存在的问题进行系统比较。最后,基于催化氧化-膜技术的未来发展方向及研究挑战提出建议和展望。
Improper treatment of biorefractory organic wastewater control of difficult to degrade organic wastewater can seriously affect the ecological environment and human health.The development of deep treatment technology for organic wastewater has become a research hotspot.Catalytic oxidation-membrane separation technology has attracted much attention as a deep water purification technology that can combine physical separation and chemical oxidation at the same time.Catalytic membrane-coupled advanced oxidation processes(AOPs)can not only promote the removal of pollutants by improving the oxidation performance,but also inhibit membrane contamination by strengthening the generation of free radicals to realize"self-cleaning".In this paper,it summarizes the preparation methods of catalytic membranes according to the status of domestic and international research progresses,and focuses on the performance and mechanism of their coupling with photocatalysis,Fenton oxidation,persulfate activation,ozone oxidation and electrocatalytic oxidation processes.Meanwhile,a systematic comparison is made for the influencing factors,advantages and their problems of catalytic membrane-coupled oxidation processes.Finally,suggestions and outlooks are presented based on the future directions and research challenges of catalytic oxidation-membrane technology.
