Description

Technical Field

[0001] The utility model relates to a filler, in particular to a filler used as a microbial carrier when treating sewage. Background Art

[0002] MBBR (Moving Bed Biofilm Reactor) is a composite process treatment method that combines the advantages of traditional activated sludge method and biological contact oxidation method. Its core part is to put a suspended carrier with a specific gravity close to that of water in the reactor, and rely on the aeration in the aeration tank and the lifting effect of the water flow to make the carrier in a fluidized state, thereby forming suspended activated sludge and attached biofilm, so that the moving bed biofilm utilizes the entire reactor space, thereby achieving the purpose of efficient decontamination. MBBR filler is a carrier of microorganisms, providing a place for the reproduction and habitat of microorganisms, and is an important product for water treatment. Among them, the key to MBBR technology lies in the research and development of biological fillers with a specific gravity close to that of water, which are easy to move freely with water under slight stirring. It has the characteristics of large effective specific surface area and is suitable for the adsorption and growth of microorganisms, strong applicability and wide application range. However, since sewage contains high-impurity large-particle pollutants and high-impurity small-particle pollutants, pollutants must be taken into consideration when designing the filler structure to reduce the blockage of the filler chamber by pollutants. When the chamber is larger, the specific surface area of ​​the filler will be smaller, that is, the attachment area of ​​microorganisms will be smaller, and the corresponding sewage treatment effect will be poor. Some products are designed with unreasonable structures, which makes the mold design impossible to achieve. This has become a problem that needs to be solved. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a biological water treatment filler with a stable product structure and a large specific surface area.

[0004] The biological water treatment filler of the utility model is a columnar body, the cross section of which is composed of two or more rings with the same center, the outermost ring of the cross section of the columnar body is toothed or wavy and the inner ring of the cross section of the columnar body is a circular ring, two adjacent rings are connected by ribs, there are multiple ribs, the ribs divide the two adjacent rings into multiple divided parts, and it is better if the divided parts have the same shape, structure and size; multiple convex points are provided on each ring of the divided part.

[0005] In order to make the product performance more stable, the distance between two adjacent rings on the cross section of the columnar body is equal.

[0006] In order to make the specific surface area larger and the product consistency higher, 16 through holes are separated between two adjacent rings by ribs, and two convex points are provided radially on the ring where each through hole is located; of course, the number of through holes separating the two rings of the product is another number, and the number of through holes between two different rings can be the same or different.

[0007] Assuming the diameter of the product is 25mm, there are 6 rings and the wall thickness is 0.12-0.48mm.

[0008] According to the biological water treatment filler described above, it has the characteristics of high production efficiency, good uniformity, not easy to be damaged by force during use, long service life, good product uniformity, easy mold design, etc. BRIEF DESCRIPTION OF THE DRAWINGS
