摘　　要：实验采用电芬顿法对甘油洗涤废水进行预处理,废水的可生化性明显提高,采用活性污泥法进一步处理电芬顿出水,处理效果较好.结果表明:在初始pH=4,恒定电流0.03A,2.0g/L的Na_2SO_4,0.5g/L的FeSO_4·7H_2O,反应60min的条件下,COD去除率约为55%,较传统芬顿试剂法提高22%.当进水COD浓度为1800mg/L左右时,经过活性污泥法,在溶解氧7.0mg/L左右,反应时间24h,污泥质量浓度4000mg/L左右的条件下,出水COD为120mg/L左右.The glycerol washing wastewater was pretreated with electric-Fenton method and then with activated sludge. The results showed that by providing the initial pH of about 4,constant current of 0.03A,the Na2SO4 concentration of 2.0g/L,the FeSO4 7H2O concentration of 0.5g/L and reaction time of 60min,the removal rate of COD is about 55% ,better than the traditional Fen- ton method. Under the condition of 7.0mg/L DO,24h reaction time and 4000mg/L MLSS,the efflu- ent COD was about 120mg/L while the inlet COD was 1800mg/L.
