摘　　要： 通过构建无媒介双室型微生物燃料电池(MFC),考察其降解啤酒废水的效果及同步产电特性。研究了外接电阻、温度和阴极曝气等条件对MFC产电的影响,监测了电池外电压和电极电势的变化过程,分析了微生物燃料电池的运行机理。通过稳态放电法得到以碳纤维布作为阳极材料的双室型微生物燃料电池的内阻为1 000Ω,最大产电功率密度为375 mW/m2。以啤酒废水为底物的MFC对COD的去除率为84%左右,外电压为0.21 V,库仑效率约为15%;而在以葡萄糖为底物的条件下,MFC的外电压为0.3 V,对COD的去除率为89%,产电性能及除污效率均有所提高。 A two chambered microbial fuel cell （MFC） without investigate brewery wastewater degradation and simultaneous electricity electron mediator was designed to generation. The effects of external resistance, temperature and cathode aeration on electricity generation were studied, the external voltage and electrode potentials were monitored, and the operation mechanism of the MFC was analyzed. In the MFC using carbon fiber cloth as anode material, the internal resistance measured using the steady dis- charging method was 1 000 Ω, and the maximal power density was 375 mW/m2. In the MFC using brew-cry wastewater as substrate, the COD removal rate was 84%, the external voltage was 0.21 V, and the coulombic efficiency was 15%. In the MFC using glucose as substrate, results showed improvements in electricity generation and pollutant removal rate, with external voltage of 0.3 V and COD removal rate of 89%.
