摘　　要：以双室微生物燃料电池(MFC)为研究对象,构建阳极为糖蜜废水、阴极为不同金属离子废水的微生物燃料电池,对其产电性能和去污能力进行测定。结果表明:微生物燃料电池可同时处理有机废水和金属离子废水,其中,Ag^+为阴极液时,其MFC稳定性最好,最高输出电压为198 m V、最大功率密度为23.1 m W/m^2、内阻为500Ω,Cu^(2+)为阴极液时分别为149 m V、13.9 m W/m^2、600Ω,Zn^(2+)为阴极液时分别为16 m V、1.9×10^(-6)m W/m^2、900Ω。阳极化学需氧量(COD)去除率以Ag^+为阴极液时最高,可达72%,Cu^(2+)和Zn^(2+)分别为54%和19.2%。阴极金属离子去除率Ag^+为72%、Cu^(2+)42%、Zn^(2+)19.8%。A dual chamber microbial fuel cell （MFC） was set up to handle both organic waste and heavy metal ions of wastewater. The anode was waste molasses, the cathode used silver nitrate, copper nitrate and zinc nitrate to simulate different metal ion wastewater, respectively. The electricity producing property and decontamination capability of MFC were measured. The results showed that MFC can process organic wastewater and metal ions wastewater at same time, the stability of the MFC is the best when using silver ion catholyte, the maximum output voltage is 198 mV, the maximum power density is 23.1 mW/m2, internal resistance of 500 Ω, the copper ion cathode of MFC is 149 mV, 13.9 mW/m2 and 600 Ω, the zinc ion cathode of MFC is 16 mV, 1.9×10-6 mW/m2 and 900 Ω, respectively. COD removal of the anode with silver ions as catholyte is up to 72%, copper ions and zinc ions are 54% and 19.2%, respectively. The metal ion removal of MFC cathode is 72% for silver ions, 42% for copper ions and 19.8% for zinc ions.
