For the establishment of both efficient organic wastewater treatment technology and recovery of electric energy, the stacked microbial fuel cells (StMFCs) by series connection of two MFCs were developed. Continuous flow experiment feeding with sugar containing wastewater (0.5 gCOD/L) was conducted to evaluate process performance of the StMFCs. Both organic concentration and composition in each anode tank was stabilized by serial connection of MFCs, StMFCs achieved good COD removal (79%) and sufficient electric generation (0.55 W/m3- each MFC) at HRT (Hydraulic retention time) of 13 hours. Also, proliferation of electricity-generating bacteria, such as genus Geobactor and genus Rhodobacter, are confirmed in each anode chamber. The increase in observed voltage value for the entire system in the series connection of the electric circuit, the increase of the observed current value for the entire system was observed in a parallel connection.

为了建立高效的有机废水处理技术和回收电能，开发了由两个MFC串联而成的堆叠式微生物燃料电池（StMFC）。进行含糖废水 (0.5 gCOD/L) 的连续流动实验，以评估 StMFC 的工艺性能。通过串联MFC，稳定了每个阳极槽中的有机物浓度和成分，StMFC在13小时的HRT（水力停留时间）下实现了良好的COD去除率（79%）和充足的发电量（0.55 W/m3-每个MFC）。另外，在各阳极室中确认了地细菌属、红细菌属等发电细菌的增殖。在电路的串联连接中观察到整个系统的观测电压值的增加，在并联连接中观察到整个系统的观测电流值的增加。
