| 摘 要： | 微生物燃料电池(MFC)利用微生物催化剂将其代谢能直接转化为电能,具有原料广泛、反应条件温和、清洁高效等优点。目前该领域仍处于实验阶段,研究用于污水处理的MFC的性能及其影响因素,对其实际应用有重要的指导意义。本研究以厌氧活性污泥为菌源,醋酸钠为底物,考察影响微生物燃料电池(MFC)处理模拟有机废水的主要因素及处理效果。结果表明:该MFC在产电的同时净化废水,其输出功率密度、产电量与初始COD呈函数关系,混合菌群可降低反应初期溶解氧对COD去除率和pH的影响。

| Abstract: | Microbial fuel cell（MFC） is a device directly converting microbial metabolic power into electricity with the microbial catalysts,which has the advantages of abundant fuel resource,mild reaction condition and high efficiency.Although it is still in experimental stage,the study of factors affecting the performance of MFC in wastewater treatment provides a significant guidance for practical application.The artificial organic wastewater containing sodium lactate was treated with anaerobic microorganisms obtained from anaerobic activated sludge.Factors affecting the performance of MFC and effect of the wastewater treatment are examined.The result shows that electricity production integrated with COD reduction in this reaction.Power density and coulombic yields in a mediator-less microbial fuel cell are examined as a function of initial COD.The influence of DO on COD removal rate and pH value is reduced by consortium. |
