THE IMPROVING METHOD FOR THE REMOVAL EFFICIENCY OF PHOSPHORUS BY RENOVATION OF THE RECTANGULAR SETTLING CLARIFIER

摘要

PURPOSE: An improvement method of phosphorus removal efficiency by a remodeling of a rectangular settling tank is provided to improve the total phosphorus removal efficiency to 99% by remodeling the rectangular settling tank into a hybrid function tub. CONSTITUTION: An improvement method of phosphorus removal efficiency by a remodeling of a rectangular settling tank comprises a step of remodeling the tank into a total phosphorous removing advanced hybrid function tub(21), capable of performing as a chemical coagulation, gravity settling, flotation and submerged-type filtering tank. A chemical cohesion unit(31,41) remodels the front side of an existing settling tank into a high speed stirring tub and a slow speed stirring tub.
