摘　　要：通过微生物燃料电池(microbial fuel cell,MFC)与传统厌氧消化(conventional anaerobic digestion,CAD)的比较试验,考察了对高浓度葡萄糖和硫酸盐人工废水的处理效果.MFC在获得一定能量的同时(I=0.16mA,P=4.76mW/m^2),有效去除水中有机物,去除率高于CAD.葡萄糖为碳源,初始TOC=2100mg/L,运行144h,MFC获得91.61%去除率,CAD获得58.85%去除率;初始NH_3-N为500mg/L,MFC中去除率最高达92.61%,CAD达72.38%;MFC中对硫酸盐的利用率和CH_4产生量都低于CAD;比较结果表明,MFC技术可提高处理高浓度有机废水的效果.Tests were conducted to compare the effect of a microbial fuel cell （MFC） reactor and a conventional anaerobic （CAD） digester on artificial wastewater with heavy concentration of glucose and sulfate. Energy was obtained in MFC （ I = 0. 16mA, P = 4. 76 mW/m^2 ） , organic matter was cut down from wastewater simultaneously. Removal rate of organic matter in MFC was higher than CAD. Glucose as carbon source, TOC = 2100mg/L originally, run time 144h, removal rateof 91.61% in MFC was obtained, 58.85% in CAD correspondingly. Original NH3-N=500mg/L,maximum removal rate of 92. 61% in MFC was obtained,72.38% in CAD correspondingly. Conversion ratio of sulfate and production of CH4 in MFC was lower than CAD. A conclusion was drawn by comparison that MFC technology can improve efficiency on heavy organic wastewater treatment.
