    摘要: A self contained sewage treatment aerobic digestion system comprises a large cylindrical, horizontally oriented fiber glass tank with an influent opening near the top of one end and an effluent opening slightly lower in the opposite end. A first partition which arises from the bottom almost to the top of the tank forms with the first end wall a pretreatment chamber. Inflow and outflow openings are offset to provide uniform circulation in the chamber. A second sloping partition divides the remainder of the tank into a central aeration chamber and a final clarifier chamber. An air diffuser line is positioned upward along one side of the central chamber near the bottom of the tank to diffuse air into the aeration chamber and to promote circulation. Openings in the second partition at and beneath water level flow aerated liquid into the clarifier tank. A skimmer projecting through the second partition returns floating solids from the clarifier to the aeration chamber. An opening at the bottom of the second partition in cooperation with the sloping wall of the partition and the sloping second end wall flows precipitated solids from the clarifier back into the aeration chamber. A weir near the effluent opening controls level of fluid within the tank, and a trough between the weir and the effluent opening provides tertiary chemical treatment of the wastewater. Manways above the first partition and above the clarifier provide access to the chambers when the entire tank system is installed underground.

    摘要: A sewage aeration tank is constructed as an elongated cylinder with a horizontal axis having a length to diameter ratio of greater than three to one. The large aeration tank is completely closed and has openings tightly surrounding sewage inlet and effluent pipes, sludge return pipes, oxygenation pipes and vent pipes. The large aeration tank and its sewage inlet, grease and trash trap, clarifier, sludge return lines from the clarifier to the aeration tank, tertiary treatment tank and outflow apparatus are buried underground. A recreational space is provided on top of the system. An air blower is housed in an equipment room of an adjacent apartment unit which the system serves, and a vent extends upward from a roof of the apartment house.
