摘　　要：本文采用阴极电Fenton法处理印染废水,并以COD去除率为指标,考察电极电压、Fe^(2+)加量、废水初始pH值和曝气量四个因素对印染废水效果的影响。结果表明四个因素均对废水处理效果有不同程度的影响;在最佳实验条件下反应120 min,COD去除率达78.12%,说明阴极电Fenton可高效降解印染废水中污染物。In this paper,the cathode electric Fenton method is used to treat dyeing wastewater,and the COD removal rate is used as an indicator to investigate the influence of electrode voltage,Fe^(2+) addition,wastewater initial pH value and aeration rate on the treatment effect of printing and dyeing wastewater.The results show that the four factors all have different degrees of influence on the wastewater treatment effect;Under the best experimental conditions,the removal rate of COD reached 78.12%,indicating that the cathode electrode Fenton can efficiently degrade pollutants in dyeing wastewater.
