More Information
Summary:The invention provides a high-density advection sedimentation tank that comprises a raw water inlet pipe, a mixing area, a flocculation reaction area, a plug flow transition area, a pre-sedimentationand sludge discharge area, a sedimentation area and a water outlet main canal which are connected in sequence; the sedimentation area is a horizontal flow sedimentation area; therefore, the advantagesof flexible mechanical flocculation adjustment and high reaction efficiency of the conventional high-efficiency clarification tank can be combined with the advantages of strong impact load resistanceand simple and convenient management of the horizontal sedimentation tank; the adaptability to raw water quantity and water quality is good; the flocculation effect is high in efficiency, effluent quality stabilization is realized, maintenance and management are convenient, the defects of insufficient water yield and water quality impact load resistance, periodic flushing or inclined tube replacement caused by easy mud flo
