nZVI负载MCS阴极用于固定化MFC-EF系统的效能研究
Study on the efficacy of nZVI loaded MCS cathode used in immobilized MFC-EF system
摘要
Abstract
A novel catalyst was prepared through calcination,liquid-phase reduction,and vacu-um freeze-drying techniques,consisting of nanoscale zero-valent iron(nZVI)supported on melamine-based carbon foam(MCS)for application in cathodic Fenton reactions.The cata-lyst also served as an anode microbial immobilization material to enhance electron transfer ef-ficiency and degradation efficiency,thereby constructing an integrated microbial fuel cell and electro-Fenton technology wastewater treatment system(IMFC-EF).The electrochemical performance and pollutant degradation effects of the IMFC-EF coupling system were investi-gated using simulated domestic sewage and industrial wastewater.Results indicated that nZ-VI was successfully loaded onto MCS,and the resulting cathode catalyst exhibited excellent characteristics such as a large specific surface area,high porosity,and easy recyclability,which improved the degradation efficiency of Rhodamine B(RhB)at the cathode(90.29％).Immobilized microorganisms effectively enhanced the microbial activity and power generation efficiency at the anode,increasing the maximum power density of the coupled system(4.86 W/m3)and improving the removal effect of anodic COD(84％).This work achieved the sim-ultaneous treatment of simulated domestic sewage and RhB,providing a new approach for the treatment of actual wastewater.关键词
