A two-chambered microbial fuel cell (MFC) with potassium ferricyanide as its electron acceptor was utilized to degrade excess sewage sludge and to generate electricity. Stable electrical power was produced continuously during operation for 250 h. Total chemical oxygen demand (TCOD) of sludge was reduced by 46.4% when an initial TCOD was 10,850 mg/l. The MFC power output did not significantly depend on process parameters such as substrate concentration, cathode catholyte concentration, and anodic pH. However, the MFC produced power was in close correlation with the soluble chemical oxygen demand (SCOD) of sludge. Furthermore, ultrasonic pretreatment of sludge accelerated organic matter dissolution and, hence, TCOD removal rate in the MFC was increased, but power output was insignificantly enhanced. This study demonstrates that this MFC can generate electricity from sewage sludge over a wide range of process parameters.
采用以铁氰化钾作为电子受体的双室微生物燃料电池（MFC）来降解剩余污泥并发电。在250小时的运行过程中持续产生稳定的电能。当初始总化学需氧量（TCOD）为10850mg/L时，污泥的TCOD降低了46.4%。MFC的功率输出并不显著依赖于诸如底物浓度、阴极电解液浓度和阳极pH值等工艺参数。然而，MFC产生的功率与污泥的可溶性化学需氧量（SCOD）密切相关。此外，污泥的超声预处理加速了有机物的溶解，因此MFC中TCOD的去除率提高了，但功率输出的增强并不显著。本研究表明，这种MFC能够在广泛的工艺参数范围内利用污水污泥发电。
