采用单室空气阴极微生物燃料电池（MFC）在两种不同的温度（23 +/- 3 ℃和30 +/- 1 ℃）和流动模式（补料分批和连续）下研究了生活污水处理。温度是影响处理效率和发电量的重要参数。在连续流和中温条件下，在54 g COD/L-d的有机负荷下，达到最高功率密度422 mW/m2（12.8 W/m3），实现25.8%的COD去除率。能量回收被发现显着依赖于操作条件（如何模式，温度，有机负荷率，HRT）以及反应器的架构。结果表明，使用温度相，串联MFC配置的生活污水处理的主要优点是节省电力，低固体产量，和更高的处理效率。(c)2009爱思唯尔有限公司保留所有权利。
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 (How 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.
