Abstract微生物燃料电池(MFC)是能在处理有机污染物时产电的装置。着重研究了MFC同步处理老龄垃圾渗滤液和其产电能力。实验在典型双室MFC装置中进行,其中以碳毡为电极材料,活性污泥为接种源,铁氰化钾溶液为阴极液。MFC驯化6个周期后产电达到稳定,此时以垃圾渗滤液和污泥作为阳极液,检测了电池的产电性能及其对垃圾渗滤液的处理效果。结果表明,经过驯化电池的最大功率密度比使用未驯化的电极对照组提高了22倍,达到了439.1 mW/m^2,电池内阻约为1 kΩ。同时扫描电镜(SEM)观察到电极表面形成一层由典型的球菌和杆菌组成的生物膜。电池运行15 d,垃圾渗滤液化学需氧量(COD)、总氮、氨氮的去除率分别达到了(49.05%±1.40%)、(68.95%±1.07%)、(73.54%±0.91%)。本研究为同步产能及处理老龄垃圾渗滤液提供了数据支持。
Other AbstractMicrobial fuel cell( MFC) is a kind of equipment that can generate electricity and degradate waste water at the same time. Synchronous degradation of mature landfill leachate and electricity production by MFC was studied. Typical dual chambers MFC with carbon felt as electrode material,activated sludge as inoculation source,and potassium hexacyanoferrate as cathode liquid was used to treat landfill leachate. Stable electricity production could be realized with the MFC after six cyclesdomestication,and with landfill leachate and activated sludge as the anode liquid,the performance comparison of the MFC with the control group without domestication on electrode and the effects on the degradation of landfill leachate were investigated. Results showed that after the domestication,the highest power density reached 439. 1 m W/m^2,which was 22 times higher than that of the control group.Besides,the internal resistance was about 1 kΩ,and a layer of typical biofilms which consisted of cocci and bacillus was formed on the surface of electrode.The COD,total N,NH4^+-N for the anode substrate( mature landfill leachate) reached removal rates of( 49. 05% ± 1. 40%),( 68. 95% ± 1. 07%),and( 73. 54% ± 0. 91%),respectively.The experimental data supported bioenergy production and mature landfill leachate treatment simultaneously.
