Domestic wastewater treatment was examined under two different temperature (23+/-3 degrees C and 30+/-1 degrees C) and flow modes (fed-batch and continuous) using single-chamber air-cathode microbial fuel cells (MFCs). Temperature was an important parameter for treatment efficiency and power generation. The highest power density of 422 mW/m(2) (12.8 W/m(3)) was achieved under continuous flow and mesophilic conditions, at an organic loading rate of 54 g COD/L-d, achieving 25.8% COD removal. Energy recovery was found to depend significantly on the operational conditions (flow mode, temperature, organic loading rate, and HRT) as well as the reactor architecture. The results demonstrate that the main advantages of using temperature-phased, in-series MFC configurations for domestic wastewater treatment are power savings, low solids production, and higher treatment efficiency.
使用单室空气阴极微生物燃料电池（MFC），在两种不同温度（23±3℃和30±1℃）和流动模式（分批进料和连续流动）下对生活污水处理进行了研究。温度是处理效率和发电的重要参数。在连续流动和中温条件下，有机负荷率为54 g COD/L·d时，实现了25.8%的COD去除率，最高功率密度达到422 mW/m²（12.8 W/m³）。发现能量回收显著取决于运行条件（流动模式、温度、有机负荷率和水力停留时间）以及反应器结构。结果表明，采用温度分段串联MFC配置处理生活污水的主要优点是节能、固体产量低和处理效率高。
