Abstract

Microbial fuel cells (MFC) can effectively control the methane emissions from constructed wetland (CW). In this study, the effect of rhizosphere locations on the reduction of methane emission from CW by operating MFC was further studied. According to results, operating MFC in CW improved the COD removal and inhibited the methane emission from CW by 1/3. Plants (Cyperus alternifolius) roots at anode were more conducive to CW-MFC power generation. The highest power density (47.813 mW/m³) was observed in CW-MFC with rhizosphere at anode. The rhizosphere in cathode could improve CW-MFC COD removal. Operating MFC led to the competition between electrogens and methanogens, which changed the microbial community structure and biochemical processes in CW. Proteobacteria, as the main electricigen in CW-MFCs, were specifically enriched in CW-MFC with rhizosphere located in cathode. As the dominant archaea, methanobacteria and methanomicrobia were specifically enriched in CW-MFC with rhizosphere located in anode.
