Fluidized-pellet-bed (FPB) bioreactor is an integrated sewage treatment system which is based on sludge biological activity regeneration,coagulation,granulation,biodegradation and solid-liquid separation.In other words,FPB is a new wastewater treatment process which combines physical with biological treatment technology.In addition,FPB bioreactor has several advantages such as short hydraulic retention time,small occupied area,high treatment efficiency,wide application range,ete[1].At the same time,it is effective to use FPB to treat wastewater of high turbidity,high chromaticity and high SS.The removal rate of SS,COD,TN and TP can reach 91.7%,89.8%,53.0%,74.8.Furthermore,the effluent can reach the primary treatment of sewage treatment plant emission standard.The activity of sludge had been regenerated in internal circulation process in the system.
