In order to solve the problem of refractory industrial wastewater, the phenol wastewater was used as the treatment object. The treatment effect of heated activated potassium persulfate oxidation on phenol wastewater was studied. The reaction time, reaction temperature, K2S2O8 dosage, pH and initial phenol concentration on the treatment effect were discussed respectively. and the reaction free mechanism analysis was carried out according to the test results. Under the conditions of heat activation at 35°C, when the initial concentration of phenol is 200 mg/L, the reaction time is 180 min, the pH is 3, m(K2S2O8): m(C6H6O) =1, the optimum removal rate of phenol was 13.61%, and the optimal removal rate of COD was 12.30%. When the temperature was raised to 85°C under the same reaction conditions, the removal rates of phenol and COD increased to 32.17% and 26.72%, respectively.
