摘要
采用厌氧流化床微生物燃料电池(AFB-MFC)对焦化废水进行生化处理,考察了直接驯化、梯度驯化和富集培养三种微生物驯化方式对系统产电性能及废水处理能力的影响。结果表明,梯度驯化时AFB-MFC产电性能和废水处理效果最好,最大功率密度为10.95m W/m2,比直接驯化和富集培养时分别提高了212%和89.4%。反应60 h后,AFB-MFC中COD的去除率为86.28%,而直接驯化和富集培养时分别为73.2%和80.01%。三种驯化方式下AFB-MFC中COD的去除都符合一级反应动力学模型。
Coking wastewater was treated in an anaerobic fluidized bed microbial fuel cell（ AFB-MFC）. The effects of three microorganism acclimatization ways（ direct acclimatization,gradient acclimatization and enrichment culture） on properties of electricity generation and wastewater treatment were investigated. The results showed that the properties of electricity generation and wastewater treatment in AFB-MFC were best under gradient acclimatization. The maximum power density was 10. 95 m W/m^2,which was higher 212% and 89. 4% than direct domestication and enrichment culture respectively. The COD removal in AFB-MFC was 86. 28% under gradient domestication,the corresponding values were 73. 2% and 80. 01% on direct acclimatization and enrichment culture. And COD removal of coking wastewater in AFB-MFC followed the first-order kinetics in three acclimatization ways.
