ABSTRACT:
The present disclosure is directed to a sewage treatment device of the marine type and operates on an extended aeration principle employing an aerator, clarifier and disinfector. The clarifier is disposed beneath the aerator and the top of the clarifier with a common wall therebetween which forms the bottom of the aerator. A first passage conducts fluid from the aerator to the clarifier and has a central port in the common wall. A second passage conducts fluid from the clarifier to the disinfector. The aerator has an influent inlet and the disinfector has an effluent outlet.
The treator includes in the aerator vessel nozzle means for admitting air to the vessel in a direction to cause fluid in the vessel to move orbitally about a vertical axis with the nozzle means being disposed at a level proximate the common wall between the aerator and clarifier. The treater also includes a device arranged in a vertical stack of cylindrical components in which the uppermost is an aeration chamber, a clarification chamber beneath the aeration chamber and in communication therewith. A clarifier discharge chamber lies beneath the aeration and clarification chambers, a chlorine contact discharge chamber is connected to the clarifier discharge chamber. There is means communicating the clarification chamber with the clarifier discharge chamber, and an anti-siphon vent means is in communication between the clarification chamber and the chlorine contact discharge chamber and lies substantially in the geometric center of the aeration chamber.
