摘要
研究考察不同体积分数的老龄垃圾渗滤液对微生物燃料电池(MFC)性能的影响。结果表明:在体积分数为40%时,MFC的产电效能最佳,输出电压最高可达370 mV,功率密度为939 mW/m^(3),且化学需氧量(COD)去除率可达43.3%;无机氮的去除与产电周期有较大关系,当体积分数为100%时,氨氮去除率可达84.1%,表明底物浓度对MFC产电和污染物的去除具有显著影响。
The effect of landfill leachate with the diffierent volume fraction on the performance of MFCs were investigated.Results show that the MFC in 40%leachate,output voltage,power density and COD removal ratio were the largest(370 mV,939 mW/m^(3) and43.3%,respectively).The removal of nitrogen in MFC had a great relationship with the production cycle,and removal rate of ammonia nitrogen can reach 84.1%when the volume fraction is 100%.It indicated that the volume fraction of substrate has an important effect on MFC power generation and pollutant removal.
