Electrochemical characteristics of microbial fuel cells treating nitrate and sulfide simultaneously(同步脱氮除硫燃料电池的电化学特性研究)

同步脱氮除硫工艺以硝态氮作为电子受体,硫化物作为电子供体,通过以废治废,去除氮硫污染物。本文构建了双室型微生物燃料电池(microbial fuel cell,MFC),将同步脱氮除硫工艺与MFC相结合,在处理废水的同时生产电能。与化学对照组相比,该同步脱氮除硫MFC具有高基质去除性能和产电性能。当进水硝态氮和硫化物的浓度分别为95.54和540 mg·L-1,反应时间为20 h时,硝态氮和硫化物的去除率分别高达96.50%和99.64%;最大电流密度达457.20 mA·m-2,稳定电流密度为30.33 mA·m-2。通过循环伏安法、极化曲线法和电化学阻抗分析,探究了同步脱氮除硫MFC的电化...
