Single-chamber microbial fuel cells (S-MFCs) with bio-anodes and activated carbon (AC) air-cathodes showed high nitrobenzene (NB) tolerance and NB removal with concomitant electricity production. The maximum power over 25Wm could be obtained when S-MFCs were operated in the NB loading range of 1.2-6.2molmd, and stable electricity production over 13.7Wm could be produced in a NB loading range of 1.2-14.7molmd. The present S-MFCs exhibited high NB removal performance with NB removal efficiency over 97% even when the NB loading rate was increased to 17.2molmd. The potential NB reduced product (i.e. aniline) could also be effectively removed from influents. The findings in this study means that single-chamber MFCs assembled with pre-enriched bio-anodes and AC air-cathodes could be developed as effective bio-electrochemical systems to remove NB from wastewaters and to harvest energy instead of consuming energy.
单室微生物燃料电池（S-MFC）采用生物阳极和活性炭（AC）空气阴极，表现出对硝基苯（NB）的高耐受性和去除能力，同时伴有电能的产生。当 S-MFC 在 NB 加载范围为 1.2-6.2molmd 时，可获得超过 25Wm 的最大功率，而在 NB 加载范围为 1.2-14.7molmd 时，可稳定地产生超过 13.7Wm 的电能。本研究中的 S-MFC 表现出高的 NB 去除性能，即使 NB 加载速率增加到 17.2molmd，NB 去除效率也超过 97%。进水的潜在 NB 还原产物（即苯胺）也可被有效去除。本研究结果表明，采用预富集生物阳极和 AC 空气阴极组装的单室 MFC 可作为有效的生物电化学系统，从废水中去除 NB 并回收能源，而不是消耗能源。
