<p>[Problem] To provide a fluidized bed-type biological treatment apparatus capable of releasing adherent gas bubbles from the carrier while preventing or limiting biofilm detachment. [Solution] The fluidized bed-type biological treatment apparatus (1) is provided with: a cylindrical tank (2) wherein the direction of the cylinder shaft center is the vertical direction; a driving axis (3) disposed at the shaft center of the tank (2); rotating blades (4) fixed to the driving axis (3); a stationary plate (8) provided in the upper part of the tank (2); rotating plates (7) provided on the driving axis (3); and a treated water-removing trough (6) provided in the upper part of the tank (2). The rotating plates (7) revolve, catching the floating carrier between the rotating plates (7) and the lower rubber part of the stationary plate (8) and releasing the gas bubbles.</p> |
