摘　　要：无机陶瓷膜具有热、结构和化学稳定性好等诸多优点,在水处理中具有巨大的应用前景,但膜污染和单一的分离功能等问题是限制其进一步应用的技术瓶颈.将陶瓷膜分离与高级氧化耦合的技术同时具备分离和催化降解双功能,可有效解决上述问题.本文综述了近年来陶瓷膜分离与臭氧、光催化耦合技术及其应用于水处理领域的国内外研究进展,重点总结了直接臭氧氧化、催化臭氧氧化、掺杂及未掺杂TiO_2光催化与陶瓷膜分离的耦合技术及其水处理应用,并简要展望了陶瓷膜分离耦合硫酸自由基高级氧化技术的可行性、优势及应用前景.Inorganic ceramic membranes have excellent thermal,structural and chemical properties,and thus show great potential for use in water treatment.However,membrane fouling and single separation functions are significant technical bottlenecks that limit their further application.The coupling of ceramic membrane separation with advanced oxidation technology offers the dual functions of separation and catalytic degradation,thus effectively solving the problems mentioned above.This article reviews recent progress in research on coupling ceramic membrane separation with ozonation and photocatalysis in the field of water treatment,especially focusing on direct ozonation oxidation,catalytic ozonation oxidation,and doped and un-doped TiO_2 photocatalysis.Furthermore,we provide a brief introduction to a promising technology involving the coupling of ceramic membrane separation with sulfate radical advanced oxidation processes and discuss its feasibility,advantages and application prospects.
