Abstract:
1. A water treatment process by catalyzing ozone with a persulfate, characterized in that: the water treatment process by catalyzing ozone with a persulfate comprises the steps of: (a) filling water subject to treatment into an ozone contact reactor; (b) simultaneously introducing ozone and adding persulfate into an ozone contact reactor such that the ozone has an initial concentration of 0.1˜40 mg/L and a molar ratio of persulfate to ozone is 1:0.1˜10, wherein a hydraulic retention time of the water subject to treatment in the ozone contact reactor is 5˜60min, and the water subject to treatment is kept at a stirring condition during the water treatment process, then the water treatment process is complete, wherein the water subject to treatment is polluted water, secondary effluent from wastewater treatment plant, water from any water source or filtered water.
