电极材料对微生物燃料电池处理老龄垃圾渗滤液性能的影响

EFFECTS OF ELECTRODE MATERIALS ON MICROBIAL FUEL CELLS'PERFORMANCE WITH TREATED-AGING LANDFILL LEACHATE AS CATHOLYTE

以碳毡和碳布为电极材料,老龄垃圾渗滤液为阳极底物构建生物阴极型微生物燃料电池(MFC),考察碳毡和碳布分别作为阴极和阳极材料时对MFC明在阳极材料相同时,碳毡阴极MFC料相同时,碳布阳极MFC输出电压和功率密度最大(分别为294 mV、95.31 mW/m^3)、化学需氧量和氨氮去除率最大(分别为58.78%、74.38%);阳极、阴极均为碳布的MFC内阻最小(308Ω),阳极、阴极均为碳毡的MFC内阻最大(347Ω)。

Bio-cathode microbial fuel cell(MFC)using carbon felt and carbon cloth as electrode materials and treatedaging landfill leachate as anolyte were investigated for their electricity production and treatment performance. As the anode materials are same,the electricity production and treatment performance of the MFC using carbon felt as cathode materials are both better than those of the MFC using carbon cloth as cathode materials. Meanwhile,the electricity production and treatment performance of the MFC using carbon cloth as anode materials are better than those of the MFCs using carbon felt-cathode MFC when the cathode materials are same. The MFC,used carbon cloth as anode material and carbon felt as cathode material,harvests maximum voltage and power density(294 mV,95.31 mW/m^3),and the highest chemical oxygen demand and ammonia removal rate(58.78%,74.38%). The minimum internal resistance is 308 Ω as carbon cloth is used as electrodes,while the maximum internal resistance is 347 Ω,when carbon felt is used as electrodes.
