Method and apparatus for treating sewage

Abstract

Abstract CONDUCTING MEANS ARE POSITIONED TRANSVERSE TO THE LONGITUDINAL FLOW AXIS OF THE SETTLING COMPARTMENT AND ABOVE THE NORMAL LIQUID LEVEL THEREIN AND CONTROL MEANS ARE PROVIDED TO DIRECT PART OF THE SLUDGE TO THE RE-AERATION COMPARTMENT AND THE BALANCE OF THE SLUDGE TO THE DIGESTION COMPARTMENT. CONDUIT MEANS MOVABLE IN SAID SETTLING COMPARTMENT TRANSVERSE TO THE LONGITUDINAL FLOW AXIS IS ASSOCIATED WITH SAID FLOW CONDUCTING MEANS FOR DELIVERY OF SLUDGE FROM THE SETTLING COMPARTMENT AND AIRLIFT MEANS INDUCES MOVEMENT OF SETTLED SLUDGE THROUGH SAID CONDUIT MEANS. AN APPARATUS FOR TREATING SEWAGE HAVING A CENTRAL ZONE COMPARTMENTALIZED TO PROVIDE IN LINE AERATION, SETTLING AND DISINFECTING COMPARTMENTS WITH A COMMON LONGITUDINAL AXIS FOR LIQUID FLOW THERETHROUGH AND HAVING A SLUDGE DIGESTION COMPARTMENT ALONG ONE LATERAL SIDE OF SAID CENTRAL ZONE AND A SLUDGE RE-AERATION COMPARTMENT ALONG THE OTHER LATERAL SIDE OF THE SAID CENTRAL ZONE MEANS ARE PROVIDED ALONG THE LATERAL SIDE OF THE AERATION COMPARTMENT RUNNING PARALLEL TO THE LONGITUDINAL FLOW AXIS, DESIGNED TO DELIVER SUPERNATANT LIQUOR WITH UNIFORM DISTIBUTION ALONG THE FULL LENGTH OF THE WALL COMMON TO THE DIGESTION COMPARTMENT AND SAID AERATION COMPARRMENT AND A RE-AERATED RECYCLE SLUDGE MEDIUM WITH UNIFORM DISTRIBUTION ALONG THE FULL LENGTH OF THE WALL COMMON TO SAID RE-AERATION COMPARTMENT AND SAID AERATION COMPARTMENT.
