Description

Technical Field

[0001] The utility model relates to the field of MBBR fillers, and particularly relates to an MBBR filler structure. Background Art

[0002] MBBR fillers are key components used in moving bed biofilm reactors, and are used to provide a large surface area for the growth and attachment of microorganisms.

[0003] Currently, a Chinese patent with the publication number CN210885481U discloses a technology in the field of microbial sewage treatment. This utility model prevents the mutual adhesion between MBBR fillers by setting anti-adhesion protrusions, resulting in the loss of effective surface area. At the same time, the MBBR is set as a filler ring structure formed by multiple regular hexagons (cross-section) ringed together, which can further increase the surface area of the MBBR filler and increase the amount of biological attachment, thereby making the sewage treatment effect better.

[0004] After the applicant reviewed the Chinese patent with the publication number CN210885481U, the following problems were found: The inner wall of the central regular hexagon attachment hole inside the filler body proposed in the existing technical solution is relatively flat, the area for microorganisms to attach is limited, and adhesion is also likely to occur at the cross-section during use. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide an MBBR filler structure, aiming to solve the problems that the inner wall of the central regular hexagon attachment hole inside the filler body proposed in the existing technical solution is relatively flat, the area for microorganisms to attach is limited, and adhesion is also likely to occur at the cross-section during use.

[0006] To achieve the above purpose, an MBBR filler structure proposed by the utility model includes an MBBR filler body. A number of regular hexagon attachment holes are opened inside the MBBR filler body. The number of the regular hexagon attachment holes is several and they are evenly distributed inside the MBBR filler body. Attachment rods are arranged on the inner wall of the regular hexagon attachment holes, and the number of the attachment rods is several.

[0007] Preferably, fixed columns are fixedly connected to the inner wall of the regular hexagon attachment holes. The number of the fixed columns is several, and one side of the attachment rod close to the fixed column is fixedly connected to the fixed column.

[0008] Preferably, rectangular attachment holes are opened inside the MBBR filler body. The number of the rectangular attachment holes is several and they are evenly distributed inside the MBBR filler body.

[0009] Preferably, anti - sticking columns are fixedly connected to both the top and bottom of the MBBR filler body, and the number of anti - sticking columns is several and they are evenly distributed on the top and bottom of the MBBR filler body.

[0010] Preferably, anti - sticking plates are fixedly connected to the surface of the MBBR filler body. The number of anti - sticking plates is six, and the surface of the anti - sticking plates is subjected to sanding treatment.

[0011] Preferably, the fixing columns and the attaching rods are both made of corrosion - resistant organic rubber.

[0012] Preferably, the MBBR filler body, the anti - sticking columns and the anti - sticking plates are all made of polyethylene.

[0013] In the technical solution of the present utility model, by fixedly connecting fixing columns and attaching rods made of corrosion - resistant organic rubber to the inner wall of the regular hexagon attaching holes, the area of the inner wall of the regular hexagon attaching holes can be increased, providing more attaching area for microorganisms. Moreover, the fixing columns and attaching rods made of corrosion - resistant materials can provide nutrients for microorganisms, and microorganisms prefer to attach to the surfaces of the fixing columns and attaching rods. Also, the rectangular attaching holes can further increase the area for microorganisms to attach. When the tops and bottoms of multiple MBBR filler bodies come into contact with each other, the anti - sticking columns can be spaced apart to prevent adhesion between the top and bottom of the MBBR filler body. The surface of the anti - sticking plate is subjected to sanding treatment to prevent adhesion between the surfaces of the MBBR filler bodies, avoiding the problems in the prior art solutions where the inner wall of the central regular hexagon attaching hole in the filler main body is relatively flat, the area for microorganisms to attach is limited, and adhesion is likely to occur at the cross - section during use.

[0028] In the technical solution of the present utility model, by fixedly connecting fixing columns 5 and attachment rods 6 made of corrosion-resistant organic rubber material to the inner wall of the regular hexagon attachment holes 7, the area of the inner wall of the regular hexagon attachment holes 7 can be increased, providing more attachment area for microorganisms. And the fixing columns 5 and attachment rods 6 made of corrosion-resistant material can provide nutrients for microorganisms. Microorganisms prefer to attach to the surfaces of the fixing columns 5 and attachment rods 6. And the rectangular attachment holes 4 can also increase the area for microorganisms to attach again.
