<p>The present invention relates to a differential pressure air diffuser which can improve the transmission efficiency of air (oxygen) for an aeration tank in an aeration process proceeding in a wastewater treatment plant and is easy for maintenance, management and replacement such as simply handling blockage and breakage without emptying the aeration tank. The differential pressure air diffuser comprises: a tank (200) wherein a first area (210) into which air flows and a second area (220) which is placed in a lower portion of the first area (210) and into which an aeration tank liquid is supplied are defined; an air inlet pipe (100) which is connected to an upper portion of the tank (200) and supplies air to the first area (210); an aeration tank liquid inlet pipe (400) which is connected to a side of the tank (200) and supplies an aeration tank liquid to the second area (220); a clean-out hole (500) which is connected to a lower portion of the tank (200) of the second area (220) and discharges foreign substances when cleaning the tank (200); and a plurality of line-mixer type pipe nozzles (300) of which one end is located on the boundary of the first and second areas (210, 220) in a side of the tank (200) and the other end is connected so as to reach the outside of the first area (210) of the tank (200).</p> |
