摘要
构建单室空气阴极微生物燃料电池(MFC)反应器,处理含硫化物的染料废水。设计硫化物浓度、染料浓度和初始pH等参数,考察MFC体系的产电效能和污染物降解。利用数据采集器记录系统的产电电压,通过紫外分光光度计测量染料浓度,并结合电化学、微生物学、水污染控制基础理论进行机理解析。结果表明,提高进水硫化物浓度能够提高MFC产电效能和染料降解率,但是硫化物去除率降低;高浓度的染料浓度对产电微生物具有一定的抑制作用;pH 7.0条件下MFC产电性能和污染物去除率最高。
A single chamber air-cathode microbial fuel cell was used to degrade dye wastewater containing sulfide.The effects of sulfide concentration,dye concentration and initial pH value on power generation efficiency and pollutant degradation of MFC system were comprehensively designed.The data collector was used to record the voltage of the system and the absorbance of dye was measured by UV spectrophotometer.The mechanism was analyzed based on the basic theoretical knowledge of electrochemistry,microbiology and water pollution control.The results show that the electricity production efficiency and dye degradation rate of MFC are improved with the increase of sulfide concentration in influent while the sulfide removal rate decreases.High concentration of dye has negative effect on exoelectrogenic bacteria and MFC has better performance under neutral conditions.
