The large-scale application of bioelectrochemical coupled anaerobic digestion (BES-AD) is limited by the matching of electrode configuration and the applicability of real wastewater. In this study, a pilot-scale BES-AD system with an effective system volume of 5 m³ and a 1 m³ volume of a carbon fiber brush electrode module was constructed and tested for treatment of the membrane manufacturing wastewater. The results showed that the BOD₅/COD of the wastewater was increased from 0.238 to 0.398 when the applied voltage was 0.9 V. The pollutants such as N, N-Dimethylacetamide and glycerol in wastewater were degraded significantly. The microorganisms in the electrode modules were spatially enriched. The fermenters (Norank_f__ML635J-40_aquatic_group, 6.55%; unclassified_f__Propionibacteriaceae, 5.25%) and degraders (Corynebacterium, 29.31%) were mostly enriched at the bottom, while electroactive bacteria (Pseudomonas, 29.39%, Geobacter, 7.86%) were mostly enriched at the top. Combined with the economical construction and operation cost ($1708.8/m³ and $0.76/m³) of the BES-AD system.

生物电化学耦合厌氧消化（BES-AD）的大规模应用受到电极配置匹配和实际废水适用性的限制。在这项研究中，构建了一个中试规模的 BES-AD 系统，其有效系统体积为 5 m ³，碳纤维刷电极模块的体积为 1 m ³，并测试了膜制造废水的处理。结果表明，当施加电压为0.9 V时，废水的BOD ₅ /COD由0.238提高到0.398，废水中的N,N-二甲基乙酰胺和甘油等污染物得到显着降解。电极模块中的微生物在空间上富集。发酵罐（Norank_f__ML635J-40_aquatic_group，6.55%；unclassified_f__Propionibacteriaceae , 5.25%)和降解菌( Corynebacterium , 29.31%)主要富集在底部，电活性菌( Pseudomonas , 29.39%, Geobacter , 7.86%)主要富集在顶部。结合 BES-AD 系统的经济建设和运营成本（$1708.8/m ³和 $0.76/m ³）。
