Two-chamber Microbial Fuel Cells (MFC) using graphite rods as electrodes were operated for simultaneous anaerobic sulfide and nitrate removal coupled with electricity generation. The MFC showed good ability to remove substrates. When the influent sulfide and nitrate concentrations were 780 mg/L and 135.49 mg/L, respectively, the removal percentages of sulfide and nitrate were higher than 90% and the main end products were nitrogen and sulfate. The MFC also showed good ability to generate electricity, and the voltage went up with the rise of influent substrate concentrations. When the external resistance was 1000 Ω, its highest steady voltage was 71 mV. Based on the linear relationship between the electrons released by substrates and accepted by electrode, it was concluded that the electricity generation was coupled with the substrate conversion in the MFC.
采用石墨棒作为电极的双室微生物燃料电池（MFC）用于同时进行厌氧硫化物和硝酸盐的去除以及发电。该 MFC 表现出良好的去除基质的能力。当进水硫化物和硝酸盐浓度分别为 780mg/L 和 135.49mg/L 时，硫化物和硝酸盐的去除率均高于 90%，主要的终产物为氮和硫酸盐。该 MFC 也表现出良好的发电能力，随着进水基质浓度的升高，电压上升。当外接电阻为 1000Ω 时，其最高稳定电压为 71mV。基于基质释放的电子与电极接受的电子之间的线性关系，可以得出结论，在 MFC 中发电与基质转化相耦合。
