FLUIDIZED BED-TYPE BIOLOGICAL TREATMENT APPARATUS

摘要

PURPOSE: A fluidized bed-type biological treatment apparatus is provided to prevent the congestion of a carrier by forming an interruption plate on the upper side of the inner circumference of a reactor body. CONSTITUTION: A carrier is filled in a reactor body(2). A rotary wing(4) is arranged on the middle of the vertical direction of the reactor body in order to stir the carrier. An interruption plate(5) is formed at the upper side of the inner circumference of the reactor body. The average density of the carrier is between 0.96 and 1.02 g/cm^3. The average particle diameter of the carrier is between 1 and 5mm. The charging rate of the carrier in the reactor body is between 5 and 50%. The interruption plate is expanded to the upper direction and to the lower direction.
