Application of microbial fuel cells (MFCs) to wastewater treatment for direct recovery of electric energy appears to provide a potentially attractive alternative to traditional treatment processes, in an optic of costs reduction, and tapping of sustainable energy sources that characterizes current trends in technology. This work focuses on a laboratory-scale, air-cathode, and single-chamber MFC, with internal volume of 6.9 L, operating in batch mode. The MFC was fed with different types of substrates. This study evaluates the MFC behaviour, in terms of organic matter removal efficiency, which reached 86% (on average) with a hydraulic retention time of 150 hours. The MFC produced an average power density of 13.2 mW/m(3), with a Coulombic efficiency ranging from 0.8 to 1.9%. The amount of data collected allowed an accurate analysis of the repeatability of MFC electrochemical behaviour, with regards to both COD removal kinetics and electric energy production.
将微生物燃料电池（MFC）应用于废水处理以直接回收电能，从降低成本以及开发符合当前技术趋势的可持续能源的角度来看，似乎为传统处理工艺提供了一种潜在的有吸引力的替代方案。这项工作聚焦于一个实验室规模的、空气阴极单室MFC，其内部容积为6.9升，以分批模式运行。该MFC采用不同类型的底物进料。本研究评估了MFC在有机物去除效率方面的行为，在水力停留时间为150小时的情况下，有机物去除效率平均达到86%。该MFC产生的平均功率密度为13.2 mW/m³，库仑效率在0.8%至1.9%之间。收集到的数据量使得能够就化学需氧量（COD）去除动力学和电能产生对MFC电化学行为的可重复性进行准确分析。
