摘　　要：为了探明厌氧流化床微生物燃料电池(AFB-MFC)产电及有机基质降解之间的关系,基于AFB-MFC阳极系统物料平衡和微生物的增长建立了有机基质降解数学模型,并基于进水流量、外电阻及有机基质浓度建立了产电模型,通过AFB-MFC系统处理高浓度有机废水试验对有机基质降解模型和产电模型进行了验证。AFB-MFC系统有机基质降解动力学模型为q=0.607S/(398.82+S),产电模型为:U=96485S/8*Q·[6×10-6S-0.0133]·Rex。In order to find out the relationship between electricity generation and organics degradation in anaerobic fluidized bed microbial fuel cell,the model of organics degradation based on mass balance and biomass growth was developed.The model o f electricity generation based on inflow,external resistance and substrate concentration of influence was also developed.The parameters of the two models were estimated and validated using experimental data obtained in an anaerobic fluidized bed microbial fuel cell used to treat high-strength organic wastewater.The model of organics degradation is q=0.607S/398.82＋S and the model of electricity generation is U=96485S/8·Q[·6×10-6S-0.0133]·Rex.
