Microbial fuel cells were designed and operated to treat landfill leachate while continuously producing power. Two different anodes were tested in batch cycles using landfill leachate as a substrate without inoculation: an activated carbon anode and biochar anode. In addition, a semi-continuous serpentine design was evaluated. No significant difference of the mean was found for the peak voltage, current density or power densities between the batch cell with activated carbon or biochar. Similar COD reduction occurred at both the batch (with biochar) and semi-continuous scale (28% ± 8.8% and 21.7% ± 12.2%, respectively). The batch MFC with activated carbon anode had significantly higher COD removal (74.7% ± 5.5%). BOD was removed by the semi-continuous MFC, but ammonia was not removed in four of the five cycles. The results provide further information on the possibility of using MFCs in landfill leachate treatment systems.
微生物燃料电池被设计并运行，以在连续发电的同时处理垃圾渗滤液。使用未经接种的垃圾渗滤液作为基质，在批量循环中测试了两种不同的阳极：活性炭阳极和生物炭阳极。此外，还评估了半连续蛇形设计。在使用活性炭或生物炭的批量电池中，峰值电压、电流密度或功率密度之间没有发现平均值的显著差异。在批量（使用生物炭）和半连续规模（分别为 28%±8.8%和 21.7%±12.2%）下，COD 减少量相似。使用活性炭阳极的批量 MFC 的 COD 去除率显著更高（74.7%±5.5%）。半连续 MFC 去除了 BOD，但在五个循环中的四个循环中氨没有被去除。这些结果提供了关于在垃圾渗滤液处理系统中使用 MFC 的可能性的进一步信息。
