Method and apparatus for the biological treatment of waste water
Abstract
Abstract METHOD AND APPARATUS FOR SUBSTANTIALLY UPGRADING THE OPERATING EFFICIENCY OF WASTE WATER TREATMENT PLANTS IS DISCLOSED. THE INVENTION UTILIZED FORCIBLY ROTATING BODIES THAT ARE PARTIALLY SUBMERGED IN THE WASTE WATER TO PROVIDE SURFACE AREA ON WHICH BIOLOGICAL SIMES DEVELOP AND SERVE THE PRUPOSE OF REMOVING POLLTANTS FROM THE WASTE WATER. THE ROTATING, PARTIALLY SUBMERGED BODIES ARE LOCATED IN THE UPPER PORTION OF THE TREATMENT TANKS, TO PROVIDE A BIOLOGICAL TREATMENT ZONE. A SUBJACENT SETTLING ZONE, PHYSICALLY SEPARATED FROM THE BIOLOGICAL TREATMENT ZONE BY A "FALSE BOTTON" OR LONGITUDINAL BAFFLE IS PROVIDED IN THE LOWER PORTION OF THE TREATMENT TANK. WASTE WATER INTRODUCED IN THE TANK IS FIRST BIOLOGICALLY TREATED AND THEN CIRCULATED THROUGH THE SUBJACENT SETTLING ZONE TO REMOVE SETTLEABLE SOLIDS.
