摘要:

微生物燃料电池(MFC)作为一种同步产电和除污的新型电化学装置,为有效处理难降解有机污染物提供了一种途径。基于阴极Fenton反应,提出了一种耦合典型双室MFC中阳极沼液产电及阴极降解有机锡的新方法。结果表明,阳极产电生物膜经驯化后MFC的最高电压提高了50.32%,而且电压稳定时间延长了1倍。MFC运行结束后,阳极沼液COD、总氮、总磷的去除率分别为85.35%±1.53%、59.20%±5.24%、44.98%±3.57%。阴极三苯基氯化锡(TPTC)的降解率随其初始浓度增加而降低。在添加100 μmol·L-1 TPTC时,MFC的最高输出电压为280.2 mV,最大功率密度为145.62 mW·m-2。TPTC在14 d后完全降解,降解效率为91.88%,降解速率约为0.273 μmol·L-1·h-1。研究结果可为利用MFC同步处理阳极有机废水和阴极有机污染物的实际应用提供基础支持。

Abstract:

As a novel electrochemical apparatus for synchronous electricity generation and decontamination, microbial fuel cell (MFC) provides a way to effectively deal with the refractory pollutant. A new method of electricity production by anodic biogas slurry coupling with cathodic triphenyltin chloride degradation was proposed based on the cathodic “Fenton” reaction in a typical dual-chamber MFC. The results showed that the maximum voltage was 50.32% higher and the stable time of the voltage was 2 times longer after biofilms domestication. In the end of the operation, the removal efficiency of COD, Total N and Total P of the biogas slurry were 85.35%±1.53%, 59.20%±5.24% and 44.98%±3.57%, respectively. Besides, the triphenyltin chloride (TPTC) degradation efficiency decreased with increasing initial concentration. In addition, when 100 μmol·L-1 TPTC was added to the cathodic chamber, the highest output voltage and the maximum power density of the MFC arrived at 280.2 mV and 145.62 mW·m-2, respectively. TPTC was removed after 14 d with the degradation of 91.88% and a rate of about 0.273 μmol·L-1·h-1. This study provided the foundational supports for simultaneously decomposing anodic organic effluent and cathodic organic pollution by MFC.
