摘要
本文采用模压成型及高温炭化法制备铁掺杂导电炭膜(FeCM),并以其为阴极构建非均相电芬顿膜反应器(EFMR),探索过硫酸盐(PDS)协同降解含N,N-二甲基乙酰胺(DMAC)废水的性能。结果表明,在PDS投加量为4 g/L,操作电压为2.1 V,pH值为7的条件下,EFMR活化PDS对DMAC降解率可达72.1%,在5次循环实验中该体系仍表现出良好的稳定性。
In this paper,an iron-doped conductive carbon membrane(FeCM)was prepared by molding and high-tempera-ture carbonization,and a hetero-geneous electro-Fenton membrane reactor(EFMR)was constructed with it as the cathode to explore the performance of peroxodisulfate(PDS)for the synergistic degradation of wastewater containing N,N-di-methylacetamide(DMAC).The results show that the removal of DMAC by EFMR-activated PDS could reach 72.1%un-der the conditions of PDS dosage of 4 g/L,operating voltage of 2.1 V,and pH 7,and the system still shows good stability in five cycle experiments.
