摘要
构建了序批式A/O-MFC运行装置,以垃圾填埋场渗滤液为底物,考察A/O-MFC在不同浓度渗滤液作为阴极液的产电性能和污染物去除效果。结果表明,MFC两极的COD、氨氮的去除率均随阴极渗滤液浓度的增加而增大,且阴极室去除效果明显好于阳极室。MFC输出电压随阴极渗滤液浓度的增加而增大,高效脉冲波动幅度随渗滤液浓度增加而减缓。最大功率密度分别0.030,0.096,0.129 W/M^2。第3阶段功率密度分别是前两个阶段4.30,1.34倍。可见,微生物燃料电池产电能力随阴极渗滤液浓度的增加而增大,处理高浓度垃圾渗滤液的A/O-MFC的除污-产电性能最好。因此,以垃圾填埋场的渗滤液作为底物运行A/O-MFC具有可行性。
A sequencing batch A/O-MFC operating device was constructed.The landfill leachate was used as a substrate to investigate the electricity generation performance and pollutant removal effect of A/O-MFC in different concentrations of leachate as catholyte.The results show that the removal rates of COD and ammonia nitrogen in MFC poles increase with the increase of cathodic leachate concentration,and the removal efficiency of cathode chamber is better than that of anode chamber.The MFC output voltage increases with the increase of the concentration of the cathode leachate,and the amplitude of the high-efficiency pulse fluctuates with the increase of the leachate concentration.The maximum power densities were 0.030,0.096 and 0.129 W/M^2,respectively.The power density of the third stage is 4.30 and 1.34 times of the first two stages,respectively.It can be seen that the power generation capacity of the microbial fuel cell increases with the increase of the concentration of the cathode leachate,and the decontamination-production performance of the A/O-MFC which treats the high-concentration landfill leachate is the best.Therefore,it is feasible to run A/O-MFC with landfill leachate as a substrate.
