摘　　要：采用电凝聚—电气浮法处理活性黄模拟印染废水。实验结果表明,在正负极换向周期为6s、电解时间为50min、搅拌转速为1 000r/min、极板间距为1.0cm、电解电压为11V、硫酸钠溶液浓度为0.010mol/L的条件下,模拟废水脱色率和COD去除率可达96%和83%以上。The simulated printing and dyeing wastewater containing reactive yellow was treated by electrocoagulation-electroflotation process. Under the conditions of anode-cathode reversing period 6 s, electrolysis time 50 min, stirring rate 1 000 r/min, plate distance 1.0 cm, electrolysis voltage 11 V and sodium sulfate concentration 0. 010 mol/L, the decolorization rate is over 96% and the COD removal rate is over 83 %.
