The aim of this work was to study Golenkinia sp. and microbial fuel cells (MFCs) for the treatment of anaerobically digested effluent from kitchen waste (ADE-KW) with different dilution factors. A dual-chamber MFC was fabricated for treating ADE-KW in the two chambers of the MFC and harvesting Golenkinia sp. All the anodic TN was removed more than 80%. COD removal efficiency increased from 48.2% to 76% when the dilution factor increased from 1 to 4. Maximum COD and TN removal rates were 3.56 and 3.71mg·L·h when ADE-KW was treated without dilution in the anodic chamber. All the cathodic TN and TP removal efficiencies were approximately 90%. The highest open circuit voltage (OCV) and power density were approximately 400mV and 400mW when ADE-KW was treated directly (undiluted) in the MFC, with the highest biomass and total lipid content production of Golenkinia sp. in the cathodic chamber.
本研究旨在研究 Golenkinia 属菌和微生物燃料电池（MFC），以处理不同稀释倍数的厨房垃圾厌氧消化液（ADE-KW）。我们构建了一个双室 MFC，用于在 MFC 的两个腔室中处理 ADE-KW 并收获 Golenkinia 属菌。所有阳极 TN 的去除率均超过 80%。当稀释倍数从 1 增加到 4 时，COD 去除效率从 48.2%增加到 76%。当在阳极室中不稀释处理 ADE-KW 时，最大 COD 和 TN 去除率分别为 3.56 和 3.71mg·L·h。所有阴极 TN 和 TP 的去除率均约为 90%。当直接（不稀释）在 MFC 中处理 ADE-KW 时，开路电压（OCV）和功率密度最高分别约为 400mV 和 400mW，同时在阴极室内获得最高的 Golenkinia 属菌生物量和总脂含量。
