| 摘 要： | 文章采用离子膜电解法对低浓度苯胺、硝基苯废水进行处理,对影响降解效果的几种因素进行了研究。实验结果表明:在常温,电压为4V,pH值为3时,电解0.5h苯胺去除率可达98.0%,硝基苯去除率为65.3%;4.5h后苯胺去除率可达99.7%,硝基苯去除率可达90.3%,TOC去除率为91.8%。同时,离子交换膜的加入还能去除废水中的盐分,为后续生化处理提供了有利条件。

| Abstract: | The use of ion-exchange membrane electrolysis method in degradation of aniline and nitrobenzene was studied to assess factors of electrolysis on the aniline and nitrobenzene degradation rate. Results showed that under normal temperature, voltage of 4V and pH of 3, the degradation rate of aniline and nitrobenzene can reach respectively 98.0% and 65.3% in half an hour while aniline, nitrobenzene and TOC can reach respectively 99.7%, 90.3% and 91.8% in 4.5hours. Salinity was also removed, which is advantageous to the next biochemical treatment. |
