Problems solved by technology

For example, there is a problem with fillers and even most water treatment carriers, that is, these carriers actually allow the thickness of the bioactive microbial layer inside the filler to grow indefinitely, which will lead to an excessive proportion of anaerobic and aerobic organisms in the biofilm and cause Insufficient carbon source leads to a decline in denitrification and denitrification capacity
Moreover, most of the fillers currently have poor fluidity, friction between fillers leads to large losses, low sewage treatment efficiency, and aerobic bacteria cannot grow favorably in this environment, resulting in weakened nitrification capacity and carbon in the denitrification process. Insufficient source supply leads to a vicious circle of poor COD degradation ability

Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides a biological carrier filler for sewage treatment, including a body 10, the body 10 is in the shape of a saddle, the two sides of the body 10 are respectively a negative side 11 and a positive side 12, and a plurality of convex surfaces are evenly distributed on the negative side 11. Ridge 111. The body 10 is designed in the shape of a saddle. This structure is different from the current common cube, cuboid, and cylinder biological carrier fillers. Fitting, using the shape of a saddle, the two bodies 10 are engaged with each other after bonding, which improves the stacking order of multiple biological carrier fillers after being put in, and reduces the loss caused by friction between biological carrier fillers . Moreover, the design of the ridge 111 can increase the surface area of ​​the shade 11 on the one hand, and can also limit the growth thickness of the active microbial layer through the height of the ridge 111 ...

Embodiment 2

[0040] Such as image 3 , Figure 4, Figure 5 As shown, on the basis of Embodiment 1, in order to improve the fluidity of the internal liquid and gas flow of the biological carrier filler, a plurality of through holes 13 penetrating the negative surface 11 and the positive surface 12 can be evenly opened on the body 10, when multiple bodies The design of the through hole 13 after 10 stacking is particularly important. Gas and liquid can pass through the through hole 13 to contact with the biofilm inside the biocarrier filler to ensure the normal growth of the biofilm. The cross-section of the through hole 13 may be a regular shape or a special shape common in the prior art, such as a regular circle, triangle, square, rhombus or regular hexagon.

[0041] The number of layers of the body 10 is 1-6 layers, the thickness of the body 10 is D, the geometric dimension of D is: 10㎜≤D≤50㎜, and the thickness D of the body 10 preferably ranges from 15㎜≤D≤25㎜.

[0042] The body 10 is ...

Embodiment 3

[0048] Such as Figure 6 As shown, on the basis of the above embodiments, the side of the main body 10 has a side wall 14, and the side wall 14 is connected between the negative surface 11 and the positive surface 12. At this time, the through hole 13 provided on the main body 10 is relatively long. 10. The stability and firmness are very good, and the side wall 14 has a smooth surface, and a smooth and dense biofilm can be formed at the position of the side wall 14.

Abstract

The invention relates to the technical field of sewage treatment, in particular to a biological supporter filler for sewage treatment. The biological supporter filler for sewage treatment comprises amain body; the main body is saddle-shaped; the two side surfaces of the main body are a yin surface and a yang surface; a plurality of convex ridges are distributed on the yin surface uniformly. The biological supporter filler limits the growth thickness of a biological membrane of an active microbial layer and avoids unlimited growth of the biological membrane through the convex ridge structure on the main body; meanwhile, by adoption of the saddle-shaped main body, the flowability is greatly improved; the yin surface and the yang surface can be superposed mutually and propped against each other after superposing to prevent loosening; compared with the traditional cubic or cylindrical biological supporter, the biological supporter filler for sewage treatment has high stability, reduces the abrasion loss of the biological supporter and improves the wastewater treatment property.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological carrier filler for sewage treatment. Background technique [0002] Fillers are widely used in the field of sewage treatment technology. They are mainly used as habitats for microorganisms and carriers of biofilms, and play an important role in sewage treatment. Microorganisms can gather on the surface of the filler to form a biofilm. With the metabolism of the biofilm, the sewage can be purified. Therefore, the performance of the filler has a direct impact on the effect of sewage treatment. Among them, the specific surface area of ​​the filler is related to the size of the microbial habitat, which in turn affects the water purification function of the filler. [0003] In the biochemical treatment of sewage, denitrifying bacteria generally grow on the inner surface of the filler and the lower part of the aerobic bacteria layer, and provide carbon source thro...
