Physicochemical Process for Treatment of Hydrogen Peroxide Wastewater

There are high-strength pollutant, water quality fluctuations, organic matter of high toxicity, low biodegradability characteristics for hydrogen peroxide wastewater. Membrane filtration /catalytic oxidation /coagulation-sedimentation process was used to treat hydrogen peroxide wastewater. The results indicate that the effluent concentrations meet the requirements of the First Grade of Wastewater Discharging Standard (GB 8978-1996) when the influent concentrations of COD, SS, iol, pH are 4500 mg.L^-1, 200 mg.L^-1, 600 mg.L^-1, from 2 to 5 respectively.
