摘要:

以2,4-二氯苯酚(2,4-DCP)为目标污染物, 在隔膜式电解槽中研究不同离子交换膜对生物膜电极法处理2,4-DCP的影响. 结果表明: 阴离子交换膜有利于2,4-DCP在生物膜电极上的转化及去除中间产物; 生物膜电极保存的时间越长, 其对2,4-DCP的降解效果越差, 生物膜电极的使用寿命逐渐下降.

Abstract:

With 2,4-dichlorophenol (2,4-DCP) as the target contaminant, in an electrolytic cell with diaphragm, the effects of different ion exchange membranes on the 2,4-DCP degradation were investigated by the biofilmelectrode. It was found that the anion exchange membrane has the better results for the conversion of 2,4-DCP and the removal of intermediaters compared to the cation exchange membrane. The longer the time of the biofilmelectrode kept is, the worse  the effect of 2,4-DCP degradation is. The service life of the biofilmelectrode gradually declines in.

Key words: biofilmelectrode, 2,4dichlorophenol(2,4DCP), chemical oxygen demand(COD), ion exchange membrane
