| 摘 要： | 为提高生物质能源利用效率，降低废水处理成本，实验构建单室无膜空气阴极微生物燃料电池（microbial fuel cell，MFC），碳布作为阴阳极材料，将牛粪沼液作为接种液及底物进行产电性能测试，同时考察了MFC对该沼液的降解效果。结果表明，MFC能够利用沼液进行产电，最高输出电压330 mV，内阻10 kW，最大功率密度为10.98 mW·m-2，沼液中的不可溶性物质是导致MFC输出电压、功率密度低的重要原因。MFC的运行对沼液中的有机物、氮、磷等物质具有一定的降解能力，24 h内去除率分别达到20.73%、67.82%、72.56%。因此，MFC作为产生电能的新方法，在联合处理沼液等有机废水节能减排方面具有广阔前景。

| Abstract: | In order to improve the efficiency of biomass energy utilization and reduce the cost for wastewater treatment, an air-cathode membrane-free microbial fuel cell (MFC) was constructed by using carbon cloth as electrode and cattle biogas slurry as anode fed. MFC could use biogas slurry to produce electricity, and the highest output voltage was 330 mV, the internal resistance was 10 kW and maximum power density was 10.98 mW·m-2 . Insoluble substance in MFC was the main reason for low output voltage and power density. After running for 24 h, the degradation rate of COD, total nitrogen and total phosphorus reached 20.73%, 67.82% and 72.56%, respectively. Therefore, MFC as a new way to generate electricity is quite promising in energy conservation and emissions reduction. |
