Microbial fuel cell (MFC) could be an efficient sludge treatment unit in regard of rates and extents of total chemical oxygen demand (TCOD) removal, particularly when ultrasound was applied to pretreat the sludge. This study characterized the organic matter in sludge before and after MFC treatment, with or without ultrasound as a pretreatment stage. The 5-d MFC tests with electric load significantly enhanced TCOD removal rate from 11.3% to 19.2% for raw sludge and from 25% to 57% for sludge pretreated with >0.6 W ml(-1) ultrasound, using conventional anaerobic digestion test (without electric load) as control. The aromatic proteins, soluble microbial byproduct-like fluorescent compounds and carboxylic components, aliphatic components (C-H related), hydrocarbon and carbohydrate materials were identified to be principally released by ultrasound pretreatment and the fuels in the present MFC study.
微生物燃料电池（MFC）在总化学需氧量（TCOD）的去除速率和程度方面可能是一种有效的污泥处理单元，特别是当超声被应用于预处理污泥时。本研究对 MFC 处理前后的污泥中的有机物进行了特征描述，有无超声预处理阶段。5 天的 MFC 测试表明，在有外加电负载的情况下，与传统的厌氧消化测试（无外加电负载）相比，未经超声预处理的污泥的 TCOD 去除率从 11.3%提高到 19.2%，而经 >0.6 W ml(-1) 超声预处理的污泥的 TCOD 去除率从 25%提高到 57%。芳香族蛋白质、可溶性微生物副产物样荧光化合物和羧酸成分、脂肪族成分（与 C-H 相关）、碳氢化合物和碳水化合物材料被确定为主要通过超声预处理和本研究中的 MFC 中的燃料释放。
