以铁氰化钾为电子受体的双室微生物燃料电池（MFC）降解剩余污泥并发电。在250 h的运行过程中连续产生稳定的电能。当初始TCOD为10，850 mg/l时，污泥的总化学需氧量（TCOD）降低了46.4%。MFC的输出功率并不显着依赖于工艺参数，如底物浓度，阴极阴极电解液浓度，阳极pH值。然而，MFC产生的功率与污泥的溶解化学需氧量（SCOD）密切相关。超声预处理加快了污泥中有机物的溶解，提高了MFC对TCOD的去除率，但功率没有显著提高。这项研究表明，这种MFC可以从污水污泥发电在很宽的工艺参数范围。(C)2009爱思唯尔有限公司保留所有权利。
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. (C) 2009 Elsevier Ltd. All rights reserved.
