The purpose of this study was to evaluate the partial oxidation of the biological treatment plant effluents using Fenton’s reagent as a pretreatment step prior to a tertiary biological oxidation of these effluents. Fenton’s reagent was evaluated as a pretreatment process for inhibitory or refractory organics. Based on the Fenton oxidation system, the petrochemical wastewater treatment plant effluent was shown to have significant improvement in toxicity after oxidation with hydrogen peroxide. For example, at ranee of 42 ∼ 184 mg/L COD of petrochemical plant effluents, the COD removal efficiencies were from 38.2% to 60.1% after reaction with hydrogen peroxide 200 mg/L and Fe2+ 100 mg/L and reaction time was 30 minutes. The total TOC reduction were about 15.8∼22.4% with same test condition and difference between the overall removal rate and BOD/COD ratio after Fenton’s oxidation estabilished in the biodegradation and otherwise meets the discharge standard or reuse for cooling tower make-up water.
