摘　　要：针对船舶舱底水乳化油难降解和微生物燃料电池(MFC)产电性能低的问题,提出使用聚吡咯/氧化石墨烯(PPy/GO)共混修饰核桃壳基生物炭作为阳极材料,使用红外光谱仪、X射线衍射仪、扫描电子显微镜、接触角测量仪等表征MFC阳极材料的结构和形貌变化,GC/MS分析测试结果表明:嗜油菌群对船舶舱底水中正构烷烃、环烷烃和多环芳烃处理效果显著,处理后的舱底水含油量≤10 mg/L;经PPy/GO修饰后的生物炭可显著提高MFC的电化学性能,利用导电性良好的GO和带有正电荷的PPy制备的复合阳极PPy/GO生物炭,能够吸引大量携带负电荷的嗜油菌附着在疏松多孔的阳极材料表面,两者协同作用可以显著提高MFC对含油污水的降解效率与产电性能。In order to solve the problems of difficult degradation of emulsified oil in Marine engine room bilge water and low power generation performance of microbial fuel cell(MFC),it was proposed to use polypyrrole/graphene oxide(PPy/GO)to blend and modify waste walnut shell biochar and apply it to MFC anode to treat ship bilge water.The structure and morphology of MFC anode materials were characterized by GC/MS,FTIR,XRD and SEM.The results of GC/MS analysis showed that the microbial flora had a significant effect on n-alkanes,cycloalkanes and polycyclic aromatic hydrocarbons in ship bilge water,the oil content of treated bilge water≤10 mg/L;biochar modified by PPy/GO can significantly improve the electrochemical performance of MFC.The composite biocarbon anode PPy/GO can attract a large number of negatively charged electric-producing microorganisms to attach to the surface of loose and porous anode materials by using GO with good conductivity and PPy with positive charge.The synergistic effect of the two can significantly improve the degradation efficiency and electricity generation performance of MFC to oily bilge water.
