Air-flotation and precipitation solid-liquid separation device for water treatment and treatment method

Abstract

The invention discloses an air-flotation and precipitation solid-liquid separation device for water treatment. The air-flotation and precipitation solid-liquid separation device comprises a flocculation area, a contact area, a separation area, a mud collection area and a precipitation water outlet area, wherein the contact area is arranged between the flocculation area and the separation area; theseparation area is connected with the precipitation water outlet area through a perforated wall of the precipitation water outlet area; the mud collection area is arranged on the lower part of the separation area; the flocculation area consists of four reaction sections and a transitional section; the reaction sections are directly partitioned through a wall body, the flocculation area consists of vertical shafts at the reaction sections, and small-hole grille plates are arranged in the vertical shafts. The invention also discloses the air-flotation and precipitation solid-liquid separation device for water treatment. According to the air-flotation and precipitation solid-liquid separation device for water treatment disclosed by the invention, through an optimized structure, the phenomenon that both of an air flotation process and a precipitation process can achieve good treatment effects is ensured, and the water outlet quality is best.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an air flotation and sedimentation solid-liquid separation device and a treatment method for water treatment. Background technique [0002] The publication number is CN1600695A (Patent No. 200410043895.3), and the invention patent titled "Air Flotation and Sedimentation Solid-liquid Separation Device" discloses a device for purifying water quality that can switch between two water treatment processes of air flotation and sedimentation. A water passage hole is opened in the middle and lower part of the baffle plate of the contact area, and a communication valve is arranged on the baffle plate of the contact area of ​​the water passage hole. Through the shell, it is fixedly connected with one end of the air-floating water outlet valve, the other end of the air-floating water outlet valve is connected with an air-floating water outlet pipe, and the upper part of the perforat...
