Through dynamic examination of electrolyses, this paper research on treatment efficiency of bipolar packed bed cell under different voltage, electrolyses time, PH value andThe experimental results show that the decompounding speed of phenol decrease with the electrolyze time increasing. With the cells voltage augment the decompounding rate of phenol increase also. But when the voltage exceed 10V, the increasing speed of decompounding rate decrease.

BPBC处理苯酚废水的实验研究结果表明，苯酚的降解速率与酚浓度呈一级反应关系，即随着实际电解时间的增加苯酚降解速率逐渐减小；随着槽电压的增大，苯酚的去除率也随之增大，但是槽电压超过10V后，苯酚去除率增加趋势减缓；在碱性条件下，pH值的变化对苯酚的去除率有一定的影响，随着pH值的增大，去除率逐渐的降低；空床流速过大时，苯酚去除率有一定的下降；投加电解质后，苯酚的去除率增加，而就投加NaCl和NaNO_3的情况下，投加等摩尔浓度的NaCl和NaNO_3，投加NaCl的效果要优于投加NaNO_3的效果；提高废水中的溶解氧有利于苯酚的去除。
