AEROBIC RESERVOIR HAVING APPARATUS FOR MAINRAINING REACTING TEMPERATURE

摘要

PURPOSE: An aeration tank is provided to maintain optimal temperature for an aerobic microorganism to act in the aeration tank without putting a separate heating device and be advantageous in an economical aspect by not requiring a separate maintenance cost. CONSTITUTION: An aeration tank installed in a sewage treatment facility comprises a water storage tank; a blower; and a blast pipe connected to the blower. The water storage tank supplies oxygen to the stored treating water. The blower is equipped outside the water storage tank and inflows the external air to the inside of the water storage tank. The blower heats and transfers the external air using a heating source operated by the blower. The blower comprises a motor(240); an impeller(230) which receives power from the motor and inhales the external air; and discharging tubes(270,290) which transfer the inhaled air to a blast pipe. The discharging tubes include a heat changing unit(280) which is in contact with the outer periphery of the motor and heats air moved by the heating source of the motor.
