阳极进水COD浓度对三室空气阴极微生物脱盐燃料电池性能的影响
|
摘要
以厌氧污泥为接种微生物构建三室空气阴极微生物脱盐燃料电池,研究阳极进水COD浓度对微生物脱盐燃料电池产电及脱盐性能的影响。结果表明,阳极进水COD浓度为800 mg/L,12 h后降解至100 mg/L以下,当在100～800 mg/L变化时,阳极出水COD浓度随进水COD浓度增加而增加,平均电压随进水COD浓度先上升后下降,脱盐率随进水COD浓度先增加后趋于平缓。阳极适量进水COD浓度有利于提高微生物脱盐燃料电池产电脱盐效率,研究结果为进一步优化微生物脱盐燃料电池反应器运行提供了参考。
A three-chamber air cathode microbial desalting cells was constructed by using anaerobic sludge as inoculating microorganisms.The effect of anode influent COD concentration on the electricity production and desalination performance of microbial desalting cells was investigated.The results show that the COD concentration of the anode influent is 800 mg/L,and it degrades to below 100 mg/L after 12 h.When the COD of the anode influent is changed from 100 to 800 mg/L,the COD concentration of the anode effluent increases with the influent COD concentration.When the increase,the average voltage decreases first and then decreases with the influent COD concentration,and the desalination ratio first increases and then tends to be gentle.The proper amount of COD in the anode is beneficial to improve the efficiency of dehydration of microbial cesalting cells.The research results provide a reference for further optimizing the operation of microbial desalting cells reactors.
