摘　　要：以颗粒活性炭为阳极、气体扩散电极为阴极,以啤酒废水为基质构建了上流式直接空气阴极生物燃料电池(UACMFC),在连续运行条件下考察了其产电性能及进水COD浓度、外接电阻对电池性能的影响。结果表明,啤酒废水的COD浓度越大,UACMFC的输出电压和输出功率就越高,当COD为1 953 mg/L时,UACMFC的最大功率密度为13.54 W/m3;随着外接电阻的增大,对COD的去除量和库仑效率不断减小。试验结果表明,以啤酒废水作为生物燃料电池的燃料进行同步发电和降解有机物具有可行性。An upflow air-cathode microbial fuel cell （UACMFC） was constructed using gas electrode as cathode, activated carbon particles as anode and beer wastewater as substrate. The electricity generation of UACMFC and the effect of COD concentration and external resistance on the performance of UACMFC were investigated under the continuous operation conditions. The results demonstrate that the greater the COD concentration of beer wastewater is, the higher the output voltage and power of UACMFC are. When COD concentration is 1953 mg/L, the maximum output power density of UACMFC is 13.54 W/m^3. The removal amount of COD and coutombic efficiency continue to reduce with the increase of external resistances. It is feasible to perform simultaneous electricity generation and ＇organics degradation by using beer wastewater as fuel for microbial fuel cell.
