以废水为基质，以厌氧污泥为接种物，可同时发电和处理废水的微生物燃料电池（MFC）是近年来出现的一种新型生物燃料电池。以输出电压、库仑效率、功率密度和TOC去除率为评价指标，采用L4（23）正交试验设计，考察了阳极尺寸、隔膜尺寸和隔膜尺寸3个非生物因素对MFC性能的影响。结果表明，通过对R值的分析，各因素的影响大小顺序为：阳极尺寸>隔膜尺寸>隔膜尺寸。综合上述三个因素，得出最佳组合为大尺寸阳极、NaF-117和大尺寸膜。同时，高TOC去除率（90%以上）和高乙酸盐消耗率（100%）显示了MFC对废水的处理能力。比较了阳离子交换膜Yumi-28在MFC中的废水处理能力和产能潜力。
Using wastewater as substrate, taking anaerobic sludge as inoculant, microbial fuel cells (MFCs) have emerged in recent years, which can generate electricity and accomplish wastewater treatment simultaneously. Based on the evaluation indexes of output voltage, coulombic efficiency, power density and TOC removal rate, three abiotic factors, anode size, membrane and membrane size, affecting MFC performance were investigated with an orthogonal experiment (L4 (23)). The results show that the impact order of factors through analyzing the value “R” was “anode size > membrane > membrane size”. The optimal set with these three factors for the performance of MFCs was big size anode, Naf-117 and big size membrane. Meanwhile, the high TOC removal rate (more than 90%) and high acetates consumed rate (100%) show the MFCs have strong ability of wastewater treatment. Cation exchange membrane Yumi-28 has compared ability of wastewater treatment and energy-production potential in MFC work.
