Aeration apparatus for wastewater treatment system

摘要

According to the present invention, the base portion is configured on the upper side of the water collecting tank; a pumping spraying unit configured from the base part to the lower water level of the water collecting tank, pumping the waste water of the upper or middle level of the water collecting tank, and then spraying it on the lower water level of the water collecting tank so that the waste water of the water collecting tank is circulated up and down; an oxygen supply unit for supplying air (oxygen) to the lower water level of the water collecting tank by spraying air (oxygen) in a venturi structure when wastewater is sprayed onto the lower water level of the water collecting tank by the pumping spray unit; an air heating unit providing a predetermined space to the base, heating the air in the space, and then supplying heated air to the lower level water level of the water collecting tank through the oxygen supply unit to maintain a predetermined temperature of the wastewater; Auxiliary oxygen that is rotatably configured in the base and partially submerged in the upper part of the water collecting tank to pump up the wastewater from the upper water level of the water collecting tank to break the wastewater into foam and then to fall so that air (oxygen) is supplied to the upper water level of the water collecting tank supply; and a microbial disk mounted on the auxiliary oxygen supply unit and configured to be partially submerged in the water in the upper layer of the water collection tank when the auxiliary oxygen supply unit is rotated so that the wastewater of the water collection tank reacts with the denitrification microorganisms to be denitrified.
