Title: PERFOMANCE OF BIOFLUIDIZED BED IN RECIRCULATING WATER PURIFICATION FOR INTENSIVE CULTURE
Abstract: Two water purification methods were compared. The biofluidized bed was 3 times higher than biofixed bed in ammonia N loading and ammonia N removal rate. Distribution and growth of bacteria on the fluidized bio particle surface was observed by electronic microscope and nutritive agar culture method. On the particle surface the biofilm was rich and well distributed. At the densities of 150 000 larvae/m 3, in fifteen days, the common carp fry grew to 12.58±0.94mm in length and 21.2mg in weight in the biofluidized bed system, and the survival rate of larvae was 90%.
