摘要:

以五氯酚(PCP)为目标污染物,在隔膜式电解槽中研究了不同离子交换膜对采用生物膜电极法处理五氯酚的影响. 结果表明,阴离子交换膜有利于五氯酚在生物膜电极上的转化和中间产物的去除;与生物法和电化学法降解五氯酚相比,采用以钛基二氧化铅为阳极(Ti/PbO2)、生物膜电极为阴极、阴离子交换膜为隔膜的电解槽处理时,五氯酚的降解效果明显优于生物法和电化学方法,经24 h处理后五氯酚的去除率和化学需氧量(COD)去除率均可达到96%(质量分数).

Abstract:

Effect of ion exchange membrane on pentachlorophenol degradation by biofilm-electrode method was studied. It was found that the use of anion exchange membrane had the better results for the PCP conversion and the intermediaters removal compared to the use of cation exchange membrane. In an electrolytic cell consisted of Ti/PbO2 anode, biofilm-electrode cathode and the anion exchange membrane diaphragm, the biofilm electrode method has much better results for the PCP degradation rate and the intermediate removal compared to the biological and electrochemical methods. The PCP degradation rate and the chemical oxygen demand(COD) removal rate can both reach 96%(mass fraction) in a treatment period of 24 h.
