Abstract: Advanced catalytic oxidation method for organic industrial wastewater degradation was investigated by using cinder added active materials as catalyst and H₂O₂ as oxidant. Results indicated that the method shows high proficiency in catalytic oxidizing organic industrial wastewater.Under the conditions of ρ（H₂O₂）/ρ（COD_Cr ）=0.6, pH=4, the degradation reaction completed within two hours with over 83% of COD_Cr removal. The catalyst is formed with cinder as carrier and FeSO₄, MnO₂, Al₂O₃ and SiO₂ as active materials.
