AIR DIFFUSER

摘要

PURPOSE: An air diffuser is provided to increase the aerobic metabolism function of activated sludge wherein the air diffuser applies an air whirlpool system to raise the activated sludge on the lower part and to implement stirring in a processing tank wherein the air passing through a guide vane is dissolved to uniformize the air solubility in the processing tank. CONSTITUTION: An air diffuser includes an air diffuser cylinder(110) positioned in a processing tank(1) and formed with an opened upper part, an injection nozzle(120) extended inside of the air diffuser cylinder and air injected into the air diffuser cylinder, and guide vanes(130) mounted inside the air diffuser cylinder to guide the air and water to make the air injected from the injection nozzle to ascend simultaneously with rotation.
