摘　　要：采用煅烧法由尿素、金属盐制备出双金属掺杂Ce&Co/g-C_(3)N_(4)单原子催化剂。用PVDF粘结到铜片载体上形成电极,以此电极构建耦合生物产电和电催化的微生物燃料电池及二级串联连续处理含盐有机胺废水的体系。结果表明,在此微生物燃料电池体系中(阴极光照、单级水力停留时间8 h),经两级反应器处理后,COD总去除率为95.1%,TN总去除率为85.8%。计算得出催化剂COD去除能力是53.46 kg/(kg·d)。A kind of high-efficiency bimetallic single atom catalyst Ce&Co/g-C_(3)N_(4) was synthesized by calcination of urea and salts.The catalyst was sopported on copper sheet using PVDF as binder.This kind of cathode electrode was used to construct microbial fuel cell reactors coupling bio-electricity production and electrocatalysis,and the two stage continous operation system,that can sequentially treat saline amine wastewater.The results showed that with cathodic photo illumination,the two stages treatment(8 h hydraulic retention time in each stage),totally removed 95.1% COD and 85.8% TN.The capacity in COD elimination per day per kg catalyst was calculated to be 53.46 kg/(kg·d).
