| 摘 要： | 通过甲基橙模拟偶氮染料废水，考察了电絮凝法处理印染废水的效果。在废水体积为500mL、溶液pH值为1.5～3.0、电极有效面积为6.0cm×4.6cm、极板间距为2.5cm、电解电压为26V时，采用电絮凝法处理90min发现甲基橙初始溶液浓度高于240mg／L时处理效果较好，其色度去除率达90％，COD去除率达80％以上。

| Abstract: | This paper explores the effectiveness of treating the printing and dyeing wastewater by electric flocculation through using methyl orange as simulated azo-dye wastewatero The findings are that the most satisfactory effectiveness is on the following conditions： volume of wastewater 500ml, pH-value of solution 1.5～3.0, effective area of electrode 6.0cm×4.6cm, spacing of polar plate 2.5cm, electrolytic voltage 26V, electric flocculation for 90min and the concentration of first solution of methyl orange higher than 240mg/L, with the rate of color-dislodging 90% and that of COD-dislodging 80% or above. |
