• Abstract：A lab-scale anaerobic attached film expanded bed reactor for treating wastewater was set up to study its operation performance under steady state. According to the operating characteristics of the AAFEB reactor and the kinetic theory of the conventional completely mixed activated sludge process,the process kinetic models of AAFEB reactor under steady state operation have been developed, which include substrate utilization kinetic model, microbial growth kinetic model and methanoge-nic kinetic model. By analyzing the data obtained from operation under steady state and the kinetic models, best estimates of kinetic parameters, sensitivity analysis for model parameters, model verification and kinetic simulation of operating parameters such as HRT, influent COD concentration and sludge concentration which affect operating performance of an anaerobic digester, were investigated.

• Key words：anaerobic attached film expanded bed  kinetics  process kinetic model  anaerobic digestion
