硫自养反硝化燃料电池脱氮除硫及产电性能的实验研究
Sulfide and nitrate removal coupled with electricity generation in sulfide autotrophic denitrification microbial fuel cell
摘要
Abstract
In this paper,the sulfide autotrophic denitrification fuel cell was set up and the two reaction processes was separated to study the effect of simultaneous denitrification and desul-furization and the capacity of electricity generation.The results show that simultaneous des-ulfurization in anode chamber and nitrate removal in cathode chamber is feasible.In this pa-per,the sulfide and nitrate removal loads were 0.36 kg·m-3·d-1and 0.07 kg·m-3·d-1,respectively.The maximum power density was 144.03 mW· m-3.Cathode chamber micro-organisms have a good ability to receive electrons.When the cathode chamber nitrate concen-tration is low,nitrate is easily reduced to nitrogen ;w hen the nitrate concentration is higher,the reaction products to nitrite mainly.The removal of the sulfide in the anode chamber and the performance of the fuel cell were less affected by the change of nitrate concentration in the cathode chamber.The external resistance mainly affects the removal of nitrate in the cathode chamber and has no effect on the removal of sulfide in the anode chamber.When the external resistance increases from 5 Ω to 2 000 Ω,the removal rate of nitrate decreases from 100%to 61.75%.Reducing the external resistance is helpful to improve the effect of nitro-gen removal in cathode of the M FC.关键词
