Study of Pretreatment of Textile Wastewater Using CaO₂/H⁺/Fe²⁺ Advanced Fenton-Like Oxidation Technology

Abstract:

The study explores pretreatment of textile Wastewater by using CaO2/H+/Fe2+ advanced Fenton-like oxidation technology. The result show that when the initial COD is 2200mg/L, the pH=3, the reaction time is 40min, the speed is 150r/min, the dosage of calcium peroxide is 24g/L and the dosage of FeSO4 is 2g/L at 25°C, the removal rate of COD reach 81.82% and the decolorization rate is 99.93%. Compared to the pure CaO2 oxidation, COD removal rate increased significantly and its processing effect is greatly increased; whereas Compared to the advanced Fenton oxidation technology, this kind of Fenton-like system greatly reduces the cost, improve the effect of effluent, provide new way for calcium peroxide used in wastewater treatment.
