Problems solved by technology

[0005] The purpose of the present invention is to provide a suspended biological filler to solve the problems in the prior art that the suspended biological filler only relies on the film formation of the filler body to cause the overall specific surface area to be small, and it is difficult to remove the film after the film formation.

Embodiment 2

[0032] Example 2, such as Figure 5-Figure 6 As shown, in this embodiment, the supporting rib 3 includes two single strips that are twisted into a twisted shape after being relatively wound, and the above-mentioned supporting ring bar 4 is also designed as a twisted structure as a whole, so that the supporting ring bar 4 and the supporting rib can be connected The entire rib 3 is designed as an attachment bed of the biofilm, and the area of ​​the attachment bed is further increased. After the single strip 7 is injection molded, it is enough to twist or weave together after winding as a whole to form a double twist structure.

[0033] In other embodiments, the supporting ribs 3 may adopt a corrugated structure, which has a certain film-hanging function.

[0034] In other embodiments, the filler carrier 1 as a whole adopts a hexahedral structure or a polyhedral structure with more faces, so that in the process of processing, each face can be welded and connected as a whole afte...

Abstract

The invention relates to a suspended biological filler.The suspended biological filler comprises a filler carrier and a plurality of filler bodies arranged in the filler carrier, the filler carrier is of a frame type hollow structure, the filler carrier is formed by encircling at least two parts of supporting frame bodies, a plurality of hollow holes are formed in the surface of the supporting frame bodies, each supporting frame body comprises a plurality of supporting ribs scattering from the center of the supporting frame body to the periphery and further comprises a plurality of supporting ring strips connected to the supporting ribs, the supporting ring strips are arranged in an internally-sleeved and externally-sleeved mode, the spaces defined by the supporting ribs form the holes, the supporting ribs and / or the supporting ring strips are / is of a screwing twist-shaped structure, and each supporting rib is provided with a biofilm hanging surface for attaching a biological membrane. The self-falling and re-implantation performance of the biological membrane is effectively improved. The metabolism of the biological membrane is facilitated.

Description

technical field [0001] The invention relates to a biological filler, in particular to a suspended biological filler. Background technique [0002] Biofilm treatment is a widely used biological treatment technology for sewage and wastewater. The feature of biofilm treatment is that in the process of sewage or wastewater treatment, the biofilm reaction tank is filled with biofilm carriers----fillers, and the fillers are submerged In the wastewater, the aerated and oxygenated wastewater flows through the filler at a certain flow rate, and the organic wastewater is treated by the microorganisms attached to the surface of the filler body, so that the wastewater is purified. Biological filler is a key component of biofilm wastewater treatment process, which directly affects the treatment effect, so it is very important to use suitable filler. [0003] For example, a Chinese invention patent document with the authorized announcement number CN103395876B discloses a swirling spheric...
