摘　　要：构建了双极室连续流联合处理废水的微生物燃料电池(MFC),该MFC阳极室的出水直接用于阴极室的进水,利用阴极室的好氧微生物进一步降解有机物.以啤酒废水作底物,研究了该MFC的产电性能和废水处理效果.结果表明,采用双极室连续流MFC可以大大提高废水的处理效果,对啤酒废水化学需氧量(COD)的总去除率可达92.2%～95.1%,其中阳极室中COD去除率为47.6%～56.5%.MFC的开路电压为0.451 V,最大输出功率为2.89 W/m3.实验中抑制MFC性能的主要因素是阴极的极化损失,通过降低进入阴极室溶液的COD浓度、采用优质的阴极材料和加大阴极室内的曝气量等方法进一步优化电池的性能.A sequential anode-cathode double-chamber MFC,in which the effluent of anode chamber was used as a continuous feed for an aerated cathode chamber,was constructed to treat brewery wastewater.The chemical oxygen demand（COD） can also be removed by heterotrophic bacteria in the cathode chamber.The performances of electricity generation and brewery wastewater treatment were studied.The results showed that the sequential anode-cathode MFC had a great potential for substrate removal in both anode and cathode.Total COD removal efficiency of 92.2%—95.1% was achieved,with COD removal efficiency of 47.6%—56.5% in anode chamber.The open circuit voltage of the MFC is 0.451 V and the maximum power output is 2.89 W/m3.According to electrode potential measurement and electrochemical impedance spectroscopy,the key limited factor was polarization loss of cathode.The performance of MFC can be optimized by decreasing COD of cathode chamber,using more superior cathode materials,increasing oxygen concentration etc.
