[0003] Deposition is that most flocculation body (alum flower) in flocculated water is under the action of gravity, deposits to the bottom of water body, forms deposition sludge, and then the bottom sludge and the upper clear water are discharged respectively, clear water is obtained, solid-liquid separation is realized, and impurities in water are removed.

[0004] Air floatation is that pressure dissolved gas water is introduced into flocculated water, and a large number of small bubbles are formed after pressure dissolved gas water is decompressed, and the bubbles adhere to flocculation body (alum flower) and impurity particles in flocculated water, to form aggregate particles of the bubbles, flocculation body (alum flower) and impurity particles, due to the presence of the bubbles, the aggregate particles obtain great buoyancy, rapidly float to the water surface, and are removed by scraping; clear water is discharged from the bottom, solid-liquid separation is realized, and impurities in water are removed.

[0054] The flocculation filler is a star umbrella, which has many snowflake-shaped small rods (vortex forming part 103) with small size and large quantity. When the water flow passes through, small turbulence is formed, and many small vortices are generated. At the same time, the large vortex generated by the water flow flowing through the vertical shaft is divided into many small vortices. According to the Kolmogrov vortex theory, as shown in the drawings, Figures 8-9As shown, the turbulent kinetic energy is mainly distributed in large eddies, and small eddies W are less. A large number of snowflake-shaped small rods will divide the large eddy W existing in the flow field into a large number of small-scale eddies, form Kolmogolov level eddies, and accelerate the eddy flocculation process of small flocs. At the same time, in the process of energy transfer, different scale eddies are constantly evolved from large eddies to small eddies in the energy conversion process, and the outer edge linear velocity of the large eddy in the flow field is greater than that of the small eddy L, thereby forming a large number of local velocity gradient change zones in the eddy evolution zone, which is conducive to the collision of flocculation particles when migrating in the eddy zone. Therefore, good flocculation hydraulic conditions are formed, the flocculation reaction is promoted to proceed efficiently, and then the flocculation body (alum flower) with compact structure and good settling performance is formed.
