摘　　要：湿地型生物燃料电池(wetland type microbial fuel cell,CW-MFC)由微生物燃料电池(microbial fuel cell,MFC)和人工湿地(constructed wetland,CW)组合而成。CW-MFC利用植物复合生物电极代替贵金属电极,湿地植物独有的根际分泌物(溶解氧、根际酶,根际有机物)和丰富的根际微生物种群结构,使电池具有更为复杂的电极结构和电极催化活性,更高效的去污能力和相对低的建设运行成本,同时CW-MFC的产电机制更为复杂。基于微生物燃料电池的工作原理,通过对CW-MFC产电机制及产电效能影响因素的综述,评述了CW-MFC电池结构、底物、电极材料、植物物种对系统效能的影响,提出了CW-MFC型电池的研究和发展方向。Wetland type microbial fuel cell（CW-MFC） is consisted of microbial fuel cell（MFC） and constructed wetland（CW）,using plants composite electrode instead of noble metal electrodes. The unique rhizosphere secretions（enzyme,dissolved oxygen,rhizosphere organic matter） and rich rhizosphere microbial population structure of wetland plants make the battery have more complex electrode structure and electrode catalytic activity. This makes CW-MFC have higher decontamination ability and much lower construction operating costs. At the same time,the electric generation mechanism is more complicated. Based on the basic principle of MFCs,this review summarizes different influencing factors on electricity production mechanism and electricity production efficiency of MFCs,including the structure of CW-MFC,substrates,electrode materials,species of plants,and puts forward research and development direction of CW-MFC.
