Active filler combined sphere with function of 3D connection

Abstract

The invention discloses an active filler combined sphere with a function of 3D connection. The combined sphere comprises a filler sphere body (1) and a spherical connecting rod (2), wherein the fillersphere body (1) is made from ethylene and has inner and outer layers, the outer sphere body (3) has a hollow fishnet structure, and the inner sphere body (4) has a rotating spherical structure; a connecting hole (5) is formed in the surface of the outer sphere body (3); and the end part of the spherical connecting rod (2) is inserted into the connecting hole (5). According to the active filler combined sphere, an arbitrary cube can be assembled by means of connection of the filler sphere body and the spherical connecting rod, and the filler has a large surface area and a large amount of adhered microorganisms. The active filler combined sphere has the advantages of good biological compatibility, quickness in microorganism biofilm forming, easily falling aged bio-film, high stability, acidand alkali resistance, oxidation resistance, biodegradation prevention, aging prevention, high oxygen inflation efficiency, light weight, great mechanical strength, long service life, no rack requirement, assembly and maintaining convenience, low price, wide application range and good adjustability.

Description

Technical field [0001] The invention relates to an active filler, in particular to an active filler composite ball capable of 3D connection. Background technique [0002] Fillers have a wide range of applications in water treatment, whether in aerobic, facultative, or anaerobic processes, fillers play an important role. Fillers can be roughly divided into fixed, suspended, dispersed and new biological fillers. The main disadvantages of traditional suspended and dispersed packing are: suspended packing requires an additional supporting design installation bracket. When the pool is high, the packing bracket is easy to collapse. The bracket material is stainless steel, which is expensive, inconvenient to install and maintain, and the pool is dredged and It is troublesome to replace the packing. The main disadvantage of dispersive fillers is that the fillers are not uniformly distributed in the pool and are prone to accumulation. The movement of the fillers is prone to collision, a...

AI Technical Summary

Problems solved by technology

The disadvantages of traditional suspended and dispersed packing mainly include: suspended packing needs to be additionally designed with mounting brackets. When the pool is high, the packing bracket is easy to collapse. It is troublesome to replace the packing

The main disadvantage of dispersed packing is that the packing is unevenly distributed in the pool, easy to accumulate, easy to collide with the packing movement, high loss rate, and easy to enter the next water treatment unit with the water flow
