| 摘 要： | 采用两瓶型微生物燃料电池(MFC)处理垃圾渗滤液,考察了其产电情况和对污染物的降解效果.结果表明:渗滤液中的有机物在阳极室得到了较好的去除,当进水COD为1 105mg/L时,对COD的去除率约为78.3%.随着渗滤液比例的增大,电流密度和功率密度逐步下降,这是由于阳极室溶液的电导率下降造成的.随着渗滤液浓度的增加,输出电压、电流密度和功率密度增大,同时MFC的产电周期明显延长,从COD为502 mg/L时的4d增加到COD为1105mg/L时的近7d.当以渗滤液为底物时,相比以乙酸钠为底物的情况,MFC的最大功率密度有所降低,从2.0 W/m3下降为0.78 W/m3,内阻也有所增大,从300Ω增加到约500Ω. |

| Abstract: | Electricity production from landfill leachate and pollutant removal efficiency were investigated with two-bottle H type microbial fuel cell(MFC).The results show that the organic pollutants are well removed in the anode.The COD removal rate is about 78.3% at the influent COD concentration of 1 105 mg/L.With the increasing of leachate proportion in the media,the current density and power density are decreased,which is due to the decreasing of conductivity.With the increasing of leachate concentration,the vol... |
