Embodiment 1

[0028] refer to figure 1 , figure 2 , image 3 As shown, a hollow tooth-shaped fluidized filler includes a body 1, teeth 2, etc.; the body 1 is hollow, with the center of the tooth shape as the center, and teeth 2 are evenly distributed on the body 1, and the number of teeth 2 is at least There are 3 pieces, preferably 3-16 pieces. The diameter of the addendum circle of the teeth 2 is 20-200mm, and the diameter of the root circle is 10-180mm. According to different water quality requirements, by increasing the number of teeth 2 or adjusting the number of teeth 2. The diameter and size ratio of the addendum circle and the dedendum circle achieve the purpose of adjusting the specific surface area: the axial length and wall thickness of the tooth 2 are equal to the length and thickness of the body 1, and the length is 20-200mm. It can be cut into segments according to actual needs. shape, the wall thickness is 0.5-1.5mm, the outer diameter of the teeth 2 is 20-200mm, and the c...

Embodiment 2

[0030] refer to Figure 4 , Figure 5 , Image 6 As shown, the overall shape of the body 1 and the teeth 2 can also be in the shape of a hollow triangular gear, and the cross-section of each tooth 2 is in the shape of a triangular tooth. All the other structures are with embodiment 1.

Embodiment 3

[0032] refer to Figure 7 , Figure 8 , Figure 9 As shown, the overall shape of the body 1 and the teeth 2 can also be in the shape of a hollow arc gear, and the cross section of each tooth 2 is in the shape of an arc tooth, which smoothly transitions with the corners of the polygonal body 1 . All the other structures are with embodiment 1.

[0033] When the present invention is used, it is directly added to the water treatment structure, and through the multi-directional force of the water flow and air bubbles on the teeth 2, it can fully drive the body 1 to realize rotation and flow in various angles and directions in the water, thereby strengthening the Mass transfer between water, air and microorganisms and on fluidized packing. The fluidized filler will make it easier for the biological community mainly composed of microorganisms to grow on the main body 1, the teeth 2 and the peaks and valleys 3 on the inner and outer surfaces, and perform reasonable shedding and ren...

Abstract

A toothed hollow fluidizing filler for bioreaction pool features that under the action of water stream and air bubbles it can rotate and flow in different directions by different angles to strengthen the mass transfer between water, gas and microbes and on said fluidizing filler. It has high adsorptive power.

Description

technical field [0001] The invention belongs to the field of biological carrier packing for water treatment, and relates to a hollow tooth-shaped fluidized packing. Background technique [0002] Biological carrier fillers are used in water and wastewater biofilm water treatment processes. When in use, after the carrier fillers are placed in the biological reaction tank, the biological community mainly composed of microorganisms can attach to the carrier and use pollutants in the water as nutrients. To achieve the purpose of purifying water. The existing biological carrier fillers are generally sheet-shaped, square, spherical, cylindrical, etc. Such carriers have the disadvantages of unreasonable structural strength design, unsatisfactory adsorption capacity, easy breakage, low production efficiency, and high transportation costs. To a certain extent, it affects the wide application of biological carrier fillers. Contents of the invention [0003] The object of the presen...
