A Study on Fluidized-pellet-bed Bioreactor Based on Sludge Activity Regeneration and Treatment Characteristics
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.
