There exist some problems in the application of catalytic ozonation and membrane separation technologies in water treatment,such as low ozone utilization,high energy consumption and membrane pollution. These problems can be solved through the coupling use of catalytic ozonation and ceramic membrane,which can increase ozone utilization rate,improve wastewater treatment efficiency,alleviate pollution to ceramic membrane,and improve the quality of treated water to meet emission standards. The research progress in catalytic ozonation coupled with ceramic membrane for wastewater treatment is reviewed and the action mechanism is described.Future development trends are expected.
