The objective of this study is to provide an initial evaluation of normalized energy recovery (NER - a new parameter for presenting energy performance) in microbial fuel cells (MFCs) through investigation of the effects of reactor dimensions and anode substrates. Although the larger-size MFCs generally have lower maximum power densities, their maximum NER is comparable to that of the smaller MFCs at the same anolyte flow rate. The mixed messages obtained from the MFC size tests suggest that MFCs can be further scaled up without decreasing energy recovery under certain conditions. The low-strength substrates seem to be more suitable for MFC treatment of wastewater, in terms of both energy recovery and organic removal. However, because the MFCs could not achieve the maximum NER and the maximum organic removal efficiency at the same time, one must determine a major goal for MFCs treating wastewater between energy recovery and contaminant removal.
本研究的目的是通过考察反应器尺寸和阳极底物的影响，对微生物燃料电池（MFC）中的归一化能量回收（NER-一种用于表示能量性能的新参数）进行初步评估。虽然较大尺寸的 MFC 通常具有较低的最大功率密度，但在相同的阳极电解液流速下，其最大 NER 可与较小的 MFC 相媲美。MFC 尺寸测试得出的相互矛盾的结果表明，在某些条件下，MFC 可以在不降低能量回收的情况下进一步放大。从能量回收和有机去除的角度来看，低强度底物似乎更适合用于 MFC 处理废水。然而，由于 MFC 不能同时达到最大的 NER 和最大的有机去除效率，因此必须在能量回收和污染物去除之间确定处理废水的 MFC 的主要目标。
