摘　　要：采用单室沉积型微生物燃料电池(SMFC)处理垃圾渗滤液与沉积污泥,考察电池的产电性能及污染物去除效果。SMFC输出电压呈周期性变化趋势,最大输出电压251 m V,最大功率密度为10.35 mW·m^(-2),功率密度随电流的增加先增大后减小,燃料电池内阻为2 653Ω。COD、氨氮去除率分别达96.18%和80.60%。SMFC的平均输出电压随污染物的降解呈波浪型上升趋势。MLSS、MLVSS去除率分别为24.40%和30.32%。实验结束后,MLVSS/MLSS的比值由0.70降至0.65,在SMFC产电过程中,污泥中的有机物得到有效降解。因此,SMFC可实现污水净化、污泥减量及产电一体化的效果。Using single-chamber sedimentary type microbial fuel cells（ SMFC） disposed of the landfill leachate and settled sludge,to investigate the production performance and pollutant removal efficiency of SMFC.The results showed cyclical variations in the SMFC output voltage,with highest output voltage of 251 m V and highest power density of 10. 35 m W·m-2. The power density first increased,and then decreased with the increase in current. The internal resistance of the SMFC was 2 653 Ω. Average removal rates for COD and ammonia nitrogen were 96. 18% and 80. 60% respectively. With the degradation of pollutants,the average output voltage of the SMFC took on a waving increase. The removal rates of MLSS and MLVSS were 24. 40% and30. 32% respectively. MLVSS / MLSS changed from 0. 70 to 0. 65 after the tests. In the process of SMFC electricity production,SMFC could effectively degrade sludge organic matter. Therefore,SMFC can achieve sewage purification,sludge reduction,and electricity generation simultaneously.
