| 摘 要： | 采用2种类型的微生物燃料电池--常规微生物燃料电池(S-MFCs，以生活污水作为产电菌群接种源、以硝酸盐作为电子受体）和改进后的微生物燃料电池（A-MFCs，以厌氧发酵液作为产电菌群接种源、以铁氰化物作为电子受体），分析了产电菌群和电子受体的改进对微生物燃料电池产电性能的影响.结果表明：产电菌群和电子受体对MFCs驯化周期和运行周期具有显著影响，使驯化周期由S-MFCs的500 h缩短到A-MFCs的430 h，运行周期由S-MFCs的100 h增加到A-MFCs的350 h；改进后的微生物燃料电池使COD去除率提升了25%，使电压输出提高了约300%.选择合适的产电菌菌种和电子受体标准电极电势是微生物燃料电池性能提升的基础. |

| Abstract: | Two types of microbial fuel cells (MFCs) were adopted to analyze the effects of exoelectrogens and electron acceptors on the electrogenesis performance of MFCs. One was conventional MFCs inoculated with sewage and using nitrate as electron acceptor (S-MFCs), and the other one was modified MFCs inoculated with anaerobic treated wastewater and using ferricyanide as electron acceptor (A-MFCs). Exoelectrogens and electron acceptors had substantial effects on the acclimation period and the power output period of MFCs. The acclimation period was reduced from 500 h for S-MFCs to 430 h for A-MFCs, and the power output period was prolonged from 100 h for S-MFCs to 350 h for A-MFCs. The modified MFCs incre ased the removal of COD and the output of voltage by 25% and 300%, respectively. To select appropriate exoelectrogens and electron accepto rs were crucial to the improvement of MFCs performance. |
