Abstract
A sewage treatment apparatus including a treatment tank with a floor, walls and having an upper aperture. A hopper having a clarifier chamber is centrally disposed in the treatment tank, maintained at a predetermined height above the treatment tank floor by hopper supports. A deflector cone is centrally disposed on the floor of the treatment tank, its vertex being received in the lower aperture of the hopper. The exterior of the hopper, the deflector cone and the inner walls of the treatment tank define an annular aerator chamber, subdivided into a plurality of aerator zones. Diffusers disposed in each aerator zone introduce oxygenation of and induce flow of sewage in the treatment tank. A cover mounted over the treatment tank aperture maintains a pressurized pocket of air above the sewage for increased oxygenation of the sewage. Treated sewage passes from the aerator zones into the clarifier chamber, then into the environment. Another embodiment of the invention includes a trash trap in fluid communication with the inlet for filtering the sewage prior to treatment. A settling tank in fluid communication with the outlet is provided for filtering the sewage prior to its voidance. A method for sewage treatment is also provided.
