Abstract:The electro-Fenton method which coupled with three-dimensional electrode was used as advanced treatment for the secondary biological effluent of papermaking wastewater. The paper analyzed the effect of different factors on wastewater treatment result to determine the optimum conditions, the removal rate of CODCr was chosen as the main index for evaluation. The results showed that when the conditions were controlled as follow: at normal temperature, initial pH value 3, electrolysis voltage of 10 V, air flow 5.1 L/min, Fe2+ concentration 0.6 mmol/L, and reaction time of 60 minutes, the removal of CODCr reached to 90.5%.The paper also analyzed the reaction kinetics of CODCr degradation.
