Abstract

In this paper, PVC paste resin (PPVC) wastewater is dealed with process integration of microeletrolysis-fenton. The influences of the pH, the Fe/C weight ratio, the residence time and the dosage of H2O2 on the COD reduction efficiency are considered. The optimal conditions of the treatment were determined as follows: pH = 3,HRT = 180 min, mFe:mC = 3:1, V = 3.0 mL/L. Compared with the single micro-electrolysis, the combined process can improve the COD reduction rate of 34.57 %, reduce the amount of H2O2 and the cost of wastewater treatment.
