Abstract: In recent years, due to the abuse of pharmaceuticals and personal care products (PPCPs), many refractory trace organic compounds (TrOCs) have been transferred into natural water bodies, posing significant challenges to the water environment. On the other hand, advanced oxidation processes (AOPs) are cleaner and more efficient than traditional biochemical degradation processes. Among them, the combined ozone/persulfate advanced oxidation process (O 3 /PMS) based on sulfate radicals (SO 4 •− ) and hydroxyl radicals (•OH) has developed rapidly in recent years. Thus, this paper summarised the reaction mechanism of O 3 /PMS and analysed its research and application progress in drinking water treatment. In addition, the process’s operation characteristics and current application scope were discussed, and the generation ways and inhibition methods of bromate and halogenates, by-products in the oxidation process, were summarised, which had a specific reference value for further research on O 3 /PMS process.
