【摘要】：以2-萘酚为目标污染物,在对比电化学法和微生物法降解效果的基础上,研究了隔膜式电解体系中基体材料性质、电解池隔膜种类、温度和电流密度对生物膜电极法降解2-萘酚作用效率的影响.结果表明,生物膜电极法相比传统的电化学法和微生物法对2-萘酚类污染物的去除有一定优势,其作用效果与微生物生长状态有直接关系.以碳毡为基体的生物膜电极降解效果起始阶段优于钛网基生物膜电极,但一段时间后钛网基生物膜电极降解性能更稳定.阴离子交换隔膜电解池体系对2-萘酚的降解效果优于阳离子交换隔膜电解池体系,35℃条件下0.5mA/cm~2电流密度是最佳作用条件.
[Abstract]:Taking 2-naphthol as the target pollutant, on the basis of comparing the degradation effect of electrochemical method and microbial method, the properties of matrix material and the type of membrane of electrolytic cell in diaphragm electrolysis system were studied. Effects of temperature and current density on the degradation efficiency of 2-naphthol by biofilm electrode. The results showed that the biofilm electrode method had some advantages over the traditional electrochemical method and microbial method in removing 2-naphthol pollutants, and the effect of biofilm electrode was directly related to the growth state of microorganisms. The degradation effect of carbon felt based biofilm electrode was better than that of titanium net-based biofilm electrode at the initial stage, but the degradation performance of titanium net-based biofilm electrode was more stable after a period of time. The degradation effect of 2-naphthol in anion exchange membrane electrolytic cell system is better than that in cationic exchange membrane electrolytic cell system at 35 鈩，
