Microbial fuel cell (MFC) technology demonstrates good potential for recovering energy from wastewater, but it has been insufficient to act as a stand-alone treatment solution because its poor effluent quality cannot meet discharge standards. This study presents a new wood-based membrane anode for MFCs, which greatly improved the removal efficiencies for chemical oxygen demand (95–97%), total nitrogen (85–91%), and total phosphorus (89–93%) from wastewater compared with a traditional carbon cloth anode. The effluent quality from the wood-anode MFC was in compliance with wastewater effluent discharge standards. Similar power outputs were obtained from MFCs equipped with different anodes (248–295 mW m⁻²), and no significant fouling was observed on the membrane anode. The long and well-aligned channels in the wood anode have high surface area, which allows cell acclimation without blocking water flow. The wood filtration anode enables MFCs to become a stand-alone technology for energy-efficient wastewater treatment.

导电木膜阳极可改善微生物燃料电池的出水质量

微生物燃料电池（MFC）技术具有从废水中回收能量的良好潜力，但由于其出水水质较差而无法满足排放标准，因此不足以作为独立的处理解决方案。这项研究提出了一种新的用于MFC的木质膜阳极，该阳极极大地提高了废水中化学需氧量（95–97％），总氮（85–91％）和总磷（89–93％）的去除效率。与传统的碳布阳极相比。木质阳极MFC的废水质量符合废水排放标准。从配备有不同阳极（248–295 mW m ^-2）的MFC获得了相似的功率输出），并且在膜阳极上未观察到明显的结垢。木质阳极中的长且排列整齐的通道具有较大的表面积，可在不阻碍水流的情况下适应细胞。木质过滤阳极使MFCs成为用于节能废水处理的独立技术。
