Microbial fuel cell (MFC) can generate electrons through microbial metabolism of organic matter in sewage. In this paper, carbon felt as base material, the conductive polymer polyaniline and polypyrrole combined with silver nanowires were doped hydrogel, a super hydrophilicity, low electron transfer resistance, good biocompatibility hydrogel MFC anode (PANI-PPy-Ag NWs/CF) prepared. It showed hand-torn bread structure, three-dimensional (3D) porous structure increased attachment amount. The could reach maximum voltage output 0.66 V only 5.5 h, produce power density 2196.61 mW/m3. Due to doping nanowire, new electronic mode was explored, coulomb efficiency 31.01% an ultra-high COD removal rate (96.69%) obtained. This study introduces composite anode, which provides idea for material diversity, electrical production sewage performance anode.
