摘　　要：采用电生成Fenton法预处理CTMP废水,主要考察了pH、电流密度、反应时间和温度对废水色度和CODC r去除率的影响,并初步探讨了电芬顿试剂的作用机理。通过实验得到最佳反应条件:极板间距10 cm、曝气、pH=5、电流密度80A/m2和反应时间60m in,最佳条件下脱色率达90%以上,CODC r去除率50%以上。The clectro-Fenton process technology was used in treating CTMP wastewater. The main influencing factors,e, g. pH, reaction time, temperature and current density, were investigated and the decoloring mechanism of electro-Fenton process was preliminary discussed. The results showed that at the optimum conditions with pH values of 5.0, 80A/m^2 of current density, and reaction time of 60min and aeriation, its color removal rate was above 90% and COD removal rate was above 50%.
