Problems solved by technology

[0007] In order to solve or at least partially solve the above-mentioned problems that the inside of the biofilter filler is easy to agglomerate, and the filler is easy to harden to form a dead zone, resulting in a decrease in the nitrification reaction efficiency of the filter and a deterioration of the effluent quality. A high-speed aeration and stripping device is installed at the bottom; through the elastic packing stripping method of this equipment, the agglomeration formed by the elastic packing will fall under the action of gravity, and will be cut and broken up multiple times in the process of cutting the bracket below; high-speed exposure The air stripping device makes the fillers squeeze, collide, and rub against each other, and finally the sludge attached to the surface of the filler peels off, which can effectively solve the problem of packing compaction, realize effective stripping of the filler, increase the water permeability and air permeability of the filler, and improve Sewage treatment efficiency

Embodiment 1

[0060] Embodiments of the present disclosure provide, on the one hand, a water treatment and defilming device, so as to solve or at least partly solve the above-mentioned problem of filler compaction. will now refer to Figure 1-5 Some example embodiments will be described. Note that in the following description, "river black and odorous water body" may be used as an example of treatment. However, the scope of the present disclosure is not limited thereto, and any water treatment and defilming equipment described here can be used within the scope of the present disclosure.

[0061] Such as figure 1 and Figure 5 As shown, generally, the water treatment stripping equipment according to the embodiment of the present disclosure includes a box body 1 and a cutting bracket.

[0062] The top of the box body 1 is open, and there is a storage space inside, which is mainly used to carry the cutting bracket and the filler floating in the middle and upper part of the box body 1; in t...

Embodiment 2

[0079] Such as Figure 6-7 As shown, the embodiments of the present disclosure provide a method for stripping elastic fillers, which is used in the above-mentioned water treatment stripping equipment. The method includes: performing stripping treatment on the elastic fillers during the nitrification process of sewage, The film-removing treatment step includes: the elastic filler is cut and scattered by a plurality of sets of shearing brackets arranged on the moving path of the elastic filler as the water level drops or rises. It can effectively solve the problem of filler compaction, realize effective stripping of filler, increase water permeability and air permeability of filler, thereby improving sewage treatment efficiency and restoring effluent water quality.

[0080] The type of sewage to be treated in this embodiment is river black and odorous water body, the inflow of the river sewage is 1000m3 / d, the influent ammonia nitrogen≤30mg / L, COD≤100mg / L, total phosphorus≤1mg / L...

Embodiment 3

[0095]The difference between embodiment 3 and embodiment 2 is that: in the initial emptying extrusion stage, the volume of the elastic packing is deformed to 55% of the original stacked volume; the remaining sludge in the packing is discharged through the first deformation extrusion, which is convenient Extrusion and stripping of the elastic packing in the later stage; the compaction of the packing can be effectively relieved; if the direct aeration backwashing is not performed for the first extrusion, the amount of sludge in the system is too large, which will cause incomplete stripping; the second emptying and extrusion The pressing stage includes: deforming the volume of the elastic filler to 75% of the original stacked volume, squeezing out the dirt in the elastic filler again, and completing the film removal.

Abstract

The invention discloses an elastic filler demolding treatment method and water treatment demolding equipment, and belongs to the technical field of water treatment demolding equipment. The equipment comprises: a box body, wherein an accommodating space is formed in the box body, the box body is provided with an upper frame net and a lower frame net, and the upper frame net and the lower frame net are both used for limiting leakage of a filler; and a plurality of groups cutting brackets respectively mounted in the box body. The cutting brackets are used for cutting or scattering the filler hardened in the box body. The plurality of groups of cutting brackets are mounted in the equipment, and the cakes fall under the action of gravity and are cut and scattered by the lower multiple layers of cutting brackets; and the problem of filler hardening can be effectively solved, effective demolding of the filler is realized, and the water permeability and air permeability of the filler are improved, so that the sewage treatment efficiency is improved, and the effluent quality is recovered. The problems that the nitration reaction efficiency of the filter is reduced and the effluent quality becomes poor due to the fact that the inside of the biological filter filler is easy to cake and the filler is easy to harden to form a dead zone are solved or at least partially solved.

Description

technical field [0001] The invention belongs to the technical field of water treatment and stripping equipment, and in particular relates to a stripping treatment method for elastic fillers and water treatment stripping equipment. Background technique [0002] As a common sewage treatment process, biological aerated filter can effectively remove suspended solids, ammonia nitrogen, organic matter and other impurities in sewage. In the biological aerated filter, the tank is filled with granular fillers such as ceramsite fillers and activated carbon fillers with high specific surface area; on the one hand, the fillers filter and block suspended solids, and on the other hand, they serve as carriers for the growth of microbial films to make organic matter, Ammonia nitrogen and the like biochemically react with the biofilm on the surface of the packing to degrade it, but the granular packing has problems such as high packing density, high resistance, and easy to cause filter block...
