摘　　要：采用电化学氧化法处理甲基橙废水,研究了电极电压、电极间距、甲基橙废水浓度、甲基橙废水pH值、NaCl质量浓度、反应时间等因素对废水中化学需氧量(COD)去除率的影响。试验结果表明,在电极间距2.0 cm、电解电压20 V、初始甲基橙溶液pH=3、NaCl质量浓度0.5 g/L、反应时间为30 min的条件下,电化学氧化处理甲基橙废水(质量浓度为500 mg/L,COD为1200 mg/L),其出水COD的去除率可达90%以上,甲基橙废水处理效果良好,方法可行。Electrochemical oxidation is used to treat methyl orange wastewater.The influencing factors on the removal rate of COD(chemical oxygen demand)from wastewater are examined,such us electrolysis voltage,electrode spacing,concentration and pH value of methyl orange wastewater,NaCl mass concentration and reaction time etc.The experimental results show that under the condition that the electrode spacing is 2.0 cm,electrolysis voltage is 20 V,initial methyl orange solution pH is 3,NaCl mass concentration is 0.5 g/L and reaction time is 30 minutes,the removal rate of COD in methyl orange wastewater treated by electrochemical oxidation with mass concentration of 500 mg/L and COD of 1200 mg/L,reaches over 90%.Electrochemical oxidation proves to be an effective method in removing COD from methyl orange wastewater.
