Problems solved by technology
[0005] (1) It is not easy to hang film. Most of the hanging fillers on the market are made of polyethylene or polypropylene materials. The surface characteristics of these materials are mostly hydrophobic, which is not easy to hang film, or the strength of the hanging film is not enough, and it is easy to fall off.
[0006] (2) It is easy to sink after hanging the film
The specific gravity of the suspended packing is only slightly lighter than that of water, and the specific gravity becomes larger after the film is attached, and it is easy to sink even in the case of aeration, which will inevitably lead to unsatisfactory treatment effect
[0007] (3) The specific surface area and porosity of the suspended filler cannot be adjusted

Embodiment 1
[0033] Such as Figure 1-2 As shown, the present embodiment provides a kind of hanging packing, comprising:
[0034] Packing 4 and a slide rail bracket 2 and a packing fixing bracket 6 for deforming the stuffing 4;
[0035] The filler has voids 5 .
[0036] The suspended packing in this embodiment can deform the packing 4 by applying pressure to the slide rail bracket 2 and the packing fixing bracket 6 , thereby adjusting the specific surface area and porosity of the hanging packing.
[0037] Preferably, the bracket includes slide rail brackets 2 arranged on opposite sides of the filler 4 and filler fixing brackets 6 capable of relative movement on the slide rail bracket 2 .
[0038] In this way, the space 5 of the filler 4 is enlarged or reduced by moving the slide rail bracket 2 and the filler fixing bracket 6 on both sides of the filler 4 away from or close to the filler 4 at the same time, so as to control the specific surface area and void ratio of the suspended filler....

Abstract
The invention provides a suspension type filler. The suspension type filler is used for solving the problems that the present filler is difficult to film formation, easy to fall off, easy to sink after the film formation and the specific area and void ratio of the filler are nonadjustable. The suspension type filler comprises a filler and a bracket used for deforming the filler, wherein the filler has a clearance. The suspension type filler provided by the invention is capable of realizing the adjustment for the specific area and void ratio of a unit volume filter chamber by adjusting the grid size according to the requirement and has the advantages of easiness in film formation, capability of maintaining suspension, big specific area, and the like.
Description
technical field [0001] The invention belongs to the field of sewage treatment, in particular to a hanging filler. Background technique [0002] In recent years, with the continuous improvement of the discharge standards of sewage treatment plants, many aeration tanks of sewage treatment plants have put biological suspension fillers into the tanks in a certain proportion during the process of upgrading standards, forming a sludge-film symbiotic sewage treatment process. The process increases the biomass and biological species in the aeration tank by adding a certain amount of suspended carrier to the aeration tank, thereby improving the treatment efficiency of the aeration tank. [0003] Biological filler is one of the pipe fittings for the contact oxidation method. As a carrier of microorganisms, biological filler affects the growth, reproduction and shedding of organisms. Its performance is directly related to the efficiency, energy consumption, infrastructure investment, s...
