Membrane separation process has realized the scale and industrial application in the field of water treatment. To further improve water purification efficiency, more and more attention has been paid to the persulfate-based advanced oxidation process(SR-AOP) integrated with membrane filtration. For this reason, the paper analyzed the mechanism and characteristics of SR-AOP. The research progress of SR-AOP/membrane combination process under various activation methods e.g. UV,Fe( Ⅱ), heterogeneous metal oxide, carbon-based material and thermal activation was reviewed. In addition, the synergistic mechanism of SR-AOP and membrane technology was systematically elaborated.Finally, the development and application prospects of SR-AOP in membrane combination process were illustrated.
