Abstract:The electro-Fenton method was used for advanced treatment of papermaking wastewater.The paper investigated the effect of different factors on treatment result to determine the optimum conditions,the chroma and COD removal rate were chosen as the evaluation indexs.The result suggested that the optimum conditions were as the follows: reaction time 120 min, initial pH value 3, electrolysis voltage of 12 V, Fe2+ concentration 0.8 mmol /L, H2O2 concentration 0.8 mmol/L, plate space 10 cm, Na2SO4 dosage 6 g/L, the chroma and CODCr removal rate were 89.5% and 68.4% respectively under the conditions.Kinetic analysis showed that the papermaking wastewater degradation curve of CODCr consisted with the first-order reaction kinetic characteristics and the value of the kinetic constant was 0.2072 min-1. |
