摘　　要：将微生物燃料电池(microbial fuel cell,MFC)与人工湿地(constructed wetland,CW)相结合是近几年来出现的一种新型产能及废水净化工艺。在综述CW-MFC耦合系统产电机理及其发展的基础上进一步分析讨论了当前研究中影响系统性能的组成要素(植物、微生物、电极及分隔材料)和运行参数(碳源、氧化还原电位及水力停留时间)两个方面,最后总结了当前尚未解决的关键问题,对今后耦合系统的潜在应用进行了展望。Constructed wetland-microbial fuel cell （CW-MFC） is a newly emerging device in which electricity can be generated by microorganisms that use wastewater and root exudates as fuel. The novelty of this system is enhanced purifying effect of treating wastewater and simultaneously electricity generation by embedding MFC into CW. The effectiveness of the system depends on the configuration of reactor, the operational and environmental parameters. Identification and optimization of these parameters are important to enhance the efficiency of the hybrid system. In this review following the introduction and explanation of the principle, the development process and the present situation of CW-MFC systems, the factors influencing the performance of the systems were described focusing on the major components including plants, microorganisms, electrodes and separators, and the impact of important variables involving carbon source, oxidation reduction potential and hydraulic retention time. The problems in this field of the CW-MFC systems were summarized and the potential applications in the future were prospected.
