利用微生物燃料电池同步降解沼液和三苯基氯化锡
Synchronously degradation of biogas slurry and triphenyltin chloride in microbial fuel cell
摘要
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.关键词
