亲水性膜材料及其功能化是膜材料和膜污染控制的研究热点。金属膜通量高，压降小，且导电性好，适合作为阴极膜耦合生物产电和膜分离，构建新型水处理系统。对此，本文通过不锈钢网上原位生长MnO2、电聚合形成聚吡咯（PPy）等方法，对商品不锈钢网进行了改性。结果表明该改性方法不仅缩小了不锈钢网孔径，达到更高的过滤精度，而且还提高了不锈钢网复合膜作为阴极的生物电化学系统的产电性能，使构建的耦合膜生物反应器和生物电化学产电的废水处理系统的水处理效率和产电性能均得到显著提高。研究还发现使用活性碳与其组合，形成更高活性的复合阴极，能进一步提高耦合体系的产电性能，使系统最大产电功率密度达到1.9W/m3，出水水质也得到改善。
 

Hydrophilic membrane materials and their functionalization is a hot spot in the field of membrane material and membrane pollution control.Although the metal film has high flux and small pressure drop,it has good electrical conductivity.So as cathode film of coupling biological electricity production system and membrane separation system is very suitable,the coupling system are new system of wastewater treatment.According to growing MnO2autochthonously in the stainless steel wire mesh and forming polypyrrole (PPy) in the way of electrochemical aggregation,modifing the nature of stainless steel wire mesh. The results show that the method not only narrow stainless steel wire mesh aperture, to achieve higher filtering accuracy;But also improve Production performancethe as a cathode electrode of biological electrochemical system, to improve water treatment efficiency and production performance of the wastewater treatment system which is coupling membrane bioreactor and biological electrochemical electricity production.The study also found, using a combination of activated carbon and modified stainless steel wire mesh form the higher activity as the composite cathode, can further improve the production performance of the coupling system, the largest producing electrical power density is 1.9 W/m3, effluent water quality is also improved.
