  • 摘要: 为有效提高脱氮效率、降低MFC运行成本，设计了一种新构型回流式无PEM膜的生物阴极微生物燃料电池，处理生活污水，回收电能。研究了该系统的启动情况及稳定运行时的污水脱氮效果和产电性能。结果表明，系统稳定运行后，输出电压0.53 V，反应器内阻406.8 Ω，最大功率密度201.9 mW/m3。连续进水、停留时间12 h、回流比为1及阴极连续曝气条件下，COD去除率85%以上，氨氮去除率93.94%，总氮去除率44.96%，总氮去除较作参比的A2/O系统提高8.17%。
    Abstract: Aiming at improving the efficiency of denitrification and reducing operating costs of MFCs, a new type of reflux PEM-less bio-cathode microbial fuel cells was designed for domestic sewage treatment and electrical energy recycle. Start-up of MFCs, sewage denitrification effects and electricity production performance under stable operation were studied. The results indicated that, the steadily operated system could provide stable output voltage of 0.53 V with internal resistance of 406.8 Ω, and the maximum power density reached to 201.9 mW/m3. It provided more than 85% COD removal efficiency, 93.94% NH3-N and 40.96% TN removal efficiency, while removal efficiency of TN increased by 8.17% compared with A2/O system under the conditions of continuous inflow,12 hours of HRT,reflux ratio equaling to 1 and continuous aeration in cathode chamber.
