A two-cylinder MFC, which is of new configuration, was constructed to study its power generation and waste water treatment performance. When the graphite granule was used in anode as packing material, the internal resistance was 38.9 Omega. The anodic resistance, ohmic resistance and the cathodic resistance were 5.1, 14.1 and 18.7 Omega respectively. The maximal power density was 6,253 mW/m3. When the concentration of COD was higher than 1,000 mg/L, the removal load was 1.6 kg/(m3 x d) and the columbic efficient was 10%-12%. When the graphite granule with the diameter of 6 mm, the graphite granule with the diameter of 3 mm, carbon felt and the improved carbon felt were used as anode packing materials, the MFCs' resistances were 47, 39, 28 and 33 Omega and the stabilization cycles were 20, 18, 11 and 18 d, respectively. Considering steadily performance, the improved carbon felt and the graphite granule with diameter of 3 mm are more suitable as anode packing material.
构建了一种新构型的双缸微生物燃料电池（MFC），以研究其发电性能和废水处理性能。当在阳极使用石墨颗粒作为填充材料时，内阻为38.9Ω。阳极电阻、欧姆电阻和阴极电阻分别为5.1Ω、14.1Ω和18.7Ω。最大功率密度为6253mW/m³。当化学需氧量（COD）浓度高于1000mg/L时，去除负荷为1.6kg/(m³·d)，库仑效率为10%-12%。当使用直径为6mm的石墨颗粒、直径为3mm的石墨颗粒、碳毡和改进型碳毡作为阳极填充材料时，MFC的电阻分别为47Ω、39Ω、28Ω和33Ω，稳定周期分别为20d、18d、11d和18d。考虑到稳定性能，改进型碳毡和直径为3mm的石墨颗粒更适合作为阳极填充材料。
