摘要: 使用双极还原法对1,4-二氯苯(1,4-DCB)工业废水进行处理,结果表明,阴极的1,4-DCB去除效率大于阳极的去除效率.在反应的前10min去除了50%以上的1,4-DCB,随进水浓度增大,去除效率变低.在酸性条件下,电极的去除效率明显提高,1,4-DCB去除效率可达90%以上.Abstract: Treatment of 1,4-dichlorobenzene(1,4-DCB) by dual-electrode reductive system formed with iron chips and activated carbon.Three key factors(reaction time,concentration of 1,4-DCB,pH values) which influence the removal of 1,4-DCB were explored in this work.The results show that the removal on the cathode is much higher than that in the anodic area.More than 50% of 1,4-DCB was removed in the first 10mins of the reaction.The removal decreased as the concentration of 1,4-DCB increased.The removal of 1,4-DCB at lower pH is much higher than that at higher pH,which could be 90% when the solution pH is 3.
