A low-cost hybrid system integrating a membrane-less microbial fuel cell (MFC) with an anoxic/oxic membrane bioreactor (MBR) was studied for fouling mitigation. The appended electric field in the MBR was supplied by the MFC with continuous flow. Supernatant from an anaerobic reactor with low dissolved oxygen was used as feed to the MFC in order to enhance its performance compared with that fed with synthetic wastewater. The voltage output of MFC maintained at 0.52±0.02V with 1000Ω resister. The electric field intensity could reach to 0.114Vcm(-1). Compared with the conventional MBR (CMBR), the contents rather than the components of foulants on the cake layer of fouled MFC-MBR system was significantly reduced. Although only 0.5% of the feed COD was translated into electricity and applied to MBR, the hybrid system showed great feasibility without additional consumption but extracting energy from waste water and significantly enhancing the membrane filterability.
一种将无膜微生物燃料电池（MFC）与缺氧/好氧膜生物反应器（MBR）集成的低成本混合系统，旨在减轻污染。MBR 中的附加电场由连续流动的 MFC 提供。用低溶解氧的厌氧反应器中的上清液代替合成废水作为 MFC 的进料，以提高其性能。MFC 的电压输出保持在 0.52±0.02V 与 1000Ω电阻。电场强度可达 0.114Vcm(-1)。与传统的 MBR（CMBR）相比，污染的 MFC-MBR 系统中饼层污垢的含量而不是成分明显减少。尽管只有 0.5%的进料 COD 转化为电能并应用于 MBR，但该混合系统无需额外消耗即可显著提高膜过滤性能，并从废水中提取能量，具有很大的可行性。
