A microbial fuel cell coupled constructed wetland (planted with Ipomoea aquatica) system (planted CW-MFC) was used for azo dye decolorization. Electricity was simultaneously produced during the co-metabolism process of glucose and azo dye. A non-planted and an open-circuit system were established as reference to study the roles of plants and electrodes in azo dye decolorization and electricity production processes, respectively. The results indicated that plants grown in cathode enhanced the cathode potential and slightly promoted dye decolorization efficiency. The electrodes promoted the dye decolorization efficiency in the anode. The planted CW-MFC system achieved the highest decolorization rate of about 91.24% and a voltage output of about 610 mV. The connection of external circuit promoted the growth of electrogenic bacteria Geobacter sulfurreducens and Beta Proteobacteria, and inhibited the growth of Archaea in anode.
采用微生物燃料电池与人工湿地（种植空心菜）耦合系统（种植 CW-MFC）对偶氮染料进行脱色。在葡萄糖和偶氮染料共代谢过程中同时产生电能。建立无植物和开路系统作为参考，分别研究植物和电极在偶氮染料脱色和产电过程中的作用。结果表明，在阴极生长的植物增强了阴极电位，略微提高了染料脱色效率。电极在阳极促进了染料的脱色效率。种植 CW-MFC 系统实现了最高约 91.24%的脱色率和约 610 mV 的电压输出。外电路的连接促进了电生成菌 Geobacter sulfurreducens 和 Beta Proteobacteria 的生长，抑制了阳极中古菌的生长。
