摘　　要：为了确定电芬顿降解印染废水的最适宜影响因素,在实验室水平下,选取罗丹明B作为降解印染废水的典型目标降解物,研究电芬顿反应的电解电压、电流密度、初始p H值、Na2SO4浓度、罗丹明B初始浓度、温度、Fe2+浓度以及曝气量对罗丹明B降解的影响。结果表明:电压为8 V、电流密度为30 m A/cm2、p H=3、初始罗丹明B浓度为10 mg/L、Fe SO4浓度为15 mmol/L、曝气量为0.3 L/min、室温条件下,罗丹明B的去除率可以达到97.5%。In order to determine the optimum factors for degradation of pollutant in dyeing wastewater,in the laboratory level,Rhodamine B was selected as a typical pollutant,the following influencing factors of electro-fenton on degradation of rhodamine B were studiedelectrolytic voltage,current density,initial pH,concentration of electrolyte,initial concentration of rhodamine B,temperature,concentration of Fe2＋and aeration.The results showed that Rhodamine B removal rate could reach 97.5%under condition that electrolytic voltage of 8V,current density was 30 mA/cm^2,pH value was 3,the initial concentration rhodamine B was 10 mg/L,FeSO4 concentration was 15 mmol/L,aeration was 0.3 L/min,and room temperature.
