是目前世界相关领域研究的热点。从不同类型光催化膜反应器的组器结构和运行方式着手,并结合课题组具体试验进展,分析了影响光催化膜反应器性能的结构和影响因素,如光源、膜材料、光催化剂和目标降解物含量、溶液pH,以及曝气、膜面流速等。由光催化和膜分离技术组合而成的新型光催化膜反应器,不仅具有其各自优点,可以有效解决废水处理中纳米催化剂粒子难分离回收的难题,同时还可产生耦合增强效应,大大提高有机废水处理的效率。认为应有效地将改性催化剂与膜分离技术耦合,针对实际废水体系的光催化降解开展研究。
The combination technology of photocatalysis and membrane separation not only has each advantage,but also leads to the coupling effect,which can solve the problem of catalyst fixation and separation in solution and greatly improves the degradation efficiency and life-span of the facility. Started with the structure of photocatalytic membrane reactors (PMR),the multifarious factors impacted efficiency of coupling technology including light source,membrane material,photocatalyst and solution concentration,pH and aeration and flow rate were analyzed in detail. Based on the recent progresses including our group's in wastewater treatment,the application of novel PMR shows a promising future.
