| Abstract: | he treatment of dry film-containing wastewater w i th oxidation-coagulating method was studied. Factors affecting Fenton reagent o xidation and coagulation, including the concentration of H2O2, the concent ration of Fe2＋, pH, temperature, time and coagulation pH, are discussed . The experiment results showed the removal rate of COD reached 87.7％, when the concentration of H2O2 was 457.0mg/L, the concentration of Fe2＋ w as 400mg/L, pH was 4.0, the time of the reaction was 180min, coagulating pH was 8～9, the quality of effluent could meet the standards. |
