摘要
微生物燃料电池(Microbial fuel cell,MFC)的研究在近几年获得了快速发展.产电微生物在厌氧条件下氧化底物释放电子和质子,电子通过导线传递给阴极,从而在外电路中形成电流,而质子通过质子交换膜进入阴极与电子和氧气结合生成水.微生物燃料电池的研究与应用开发涉及到从微生物、电化学到材料学和环境工程等科学领域的交叉,特别是废水处理能与微生物产电相结合的研究成果,使污水、污泥、垃圾等环境污染物的治理有可能成为生物质能源的生产过程,展示了微生物燃料电池的广泛应用前景.本文着重综述微生物燃料电池在构造上的进展,并介绍了其在水处理中的应用前景.
The research of microbial fuel cells （MFC） has made great progress in recent years. Electrogenic bacteria oxidize substrate under anaerobic conditions and release electrons and protons. Electrons are passed to the electrode through wire, so the electricity is produced in the outer circuit, while protons migrate to the counter electrode so that they can combine electrons and oxygen to form water. The research and application of the MFC require the cooperation in many fields, such as microbiology, electrochemistry, material science and environmental engineering. The research results from the combination of wastewater treatment with electricity generation reveal the wide application of the MFC in the future. It makes the treatment process of wastewater, sludge and solid waste become a possible production process of bioenergy. This paper reviews the construction progress of the MFC, and discusses its application prospect in wastewater treatment. Fig 8, Ref 56
