<p>PROBLEM TO BE SOLVED: To provide a liquid dispersing nozzle capable of being raised smoothly and capable of performing effective biodegradation treatment. SOLUTION: The liquid dispersing nozzle is attached to the liquid dispersing nozzle hole bored in the carrier receiving plate dividing a fluidized bed type bioreactor up and down and a roof part, which is disposed above the liquid dispersing nozzle hole and has an almost conical shape of which the diameter becomes small upwardly, and the sidewall part, which is almost suspended from the peripheral edge part of the lower end of the roof part to reach the carrier receiving plate, are arranged on the liquid dispersing nozzle and an opening part is formed at the almost lower end of the side wall part. A weir bank part lower than the sidewall part is vertically formed at the entire periphery of the liquid dispersing nozzle hole on the upper surface of the carrier receiving plate and the angle of inclination of the roof part with respect to horizontality is set to about 20-40 deg..</p> |
