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.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.
