Microbial electrochemical systems (MESs) can be incorporated with membrane filtration that assists the bioelectrochemical treatment. Herein, a dynamic membrane (DM) was created on the carbon cloth-based anode electrode in a dynamic membrane microbial electrochemical system (DMES) and evaluated for treating domestic wastewater. The advantage of this DMES was demonstrated via comparing to the one without DM filtration. It was found that DMES achieved a current density of 15.75 ± 0.86 A m⁻³ at 10 Ω, which is significantly higher than that of the control system with no DM filtration (6.60 ± 0.22 A m⁻³). Moreover, the DMES effluent had a turbidity of 11.1 ± 0.3–16.7 ± 0.5 NTU under the varied water fluxes, which is much lower than that from the control system (29.3 ± 0.8–34.8 ± 0.5 NTU). The use of a stainless-steel current collector as a part of DM could increase the current generation. However, adding one more layer of DM showed a limited improvement of the DMES performance at the expense of an additional capital cost. When fed with actual domestic wastewater for an extended operation for 30 days, DMES showed relatively stable treatment performance and was able to maintain turbidity lower than 5 NTU. This study has provided the initial results of employing the DM concept in the anode of an MES for enhanced treatment performance and electricity generation. Several challenges to be addressed were identified and discussed with further investigation.

以碳基动态膜作为阳极和过滤介质，增强微生物电化学系统的性能

微生物电化学系统（MESs）可与有助于生物电化学处理的膜过滤结合使用。本文中，在动态膜微生物电化学系统（DMES）中的碳布基阳极上创建了动态膜（DM），并对其进行了处理生活废水的评估。通过与不带DM过滤的DMES进行比较，证明了DMES的优势。发现DMES在10Ω时实现了15.75±0.86 A m ^-3的电流密度，这明显高于没有DM过滤的控制系统的电流密度（6.60±0.22 A m ^-3））。此外，在变化的水通量下，DMES出水的浊度为11.1±0.3–16.7±0.5 NTU，远低于控制系统的浊度（29.3±0.8–34.8±0.5 NTU）。使用不锈钢集电器作为DM的一部分可以增加电流的产生。但是，增加一层DM会显示DMES性能的有限改善，但会增加额外的资本成本。当使用实际的生活污水进行30天的扩展操作时，DMES的处理性能相对稳定，并且能够将浊度保持在5 NTU以下。这项研究提供了在MES阳极中采用DM概念以增强处理性能和发电的初步结果。
