废水

There are some midst matters in wastewater, for removal of these matters the electrolyze time should exceed 30 min. The experimental results show that the bipolar packed bed cell has best treatment efficiency of phenol wastewater under condition that voltage is 10V, electrolyses time is 30 min, and velocity of flow is 1.03 cm/min.Basic on the study on treating of phenol wastewater, this paper carry on a research on treating of circuitry board film wastewater by bipolar packed bed cell.

本文在以上处理苯酚废水研究的基础上，论文研究了BPBC处理两种不同浓度得脱膜废水，试验结果表明，对于浓度较高的酸化气浮-光酚顿的出水，在外加氧化剂双氧水后，最佳处理工艺：槽电压8V，实际电解时间60min，双氧水的投加量为1倍理论药量，pH值为3，COD的去除率达到60%；在酸化气浮过程采用酸铜废液调节pH值将会降低COD的去除率。

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。
