Problems solved by technology
[0003] However, the microbial carrier of the contact oxidation tank process is evenly fixed on the bottom of the pool, but it is difficult to repair the microbial carrier after it is damaged
The microbial carrier (MBBR filler) of MBBR process is easy to gather at the water outlet with the water flow, and the microbial carrier (MBBR filler) is unevenly distributed in the pool, and it is easy to cause the outlet to be blocked

Embodiment approach
[0034] Such as image 3 with Figure 4 As shown, this application also provides an implementation manner, which is specifically as follows:
[0035] In this embodiment, the cage-shaped shell is a sphere, which is woven by warp and weft; it is divided into two hemispheres, and the two hemispheres are assembled into one body by a connecting piece. The connecting piece can be connected by a snap-fit connection. The combined cage-shaped shell can be used to enclose the microorganism carrier. The distance between two adjacent weft threads does not exceed the outer diameter of the microorganism carrier. Specifically, the diameter of the cage-shaped housing is 1000 mm, and the distance between two adjacent weft wires is 14 mm. The cage-shaped shell provided in this embodiment can enclose the microbial carrier in the cage. For example, the size of the microbial carrier is 20mm*20mm*20mm or 40mm*40mm*40mm.

Abstract
The invention discloses a cage type microbial carrier fixing biochemical pool. The biochemical pool comprises a biochemical pool body, a fixing device is arranged in the biochemical pool body, and a plurality of cage type microbial filler structures are fixed on the fixing device; and each cage-shaped microbial filler structure comprises a cage-shaped shell with holes, the cage-shaped shells are filled with a microbial carrier, and the hole diameter of the cage-shaped shells is smaller than the outer diameter of the microbial carrier. The cage-type microbial carrier of the biochemical pool cannot be gradually gathered to the water outlet end of the biochemical pool along with water flow, so that blockage caused by gathering of the microbial carrier at the water outlet of the biochemical pool is avoided, and the distribution uniformity of the microbial carrier in the biochemical pool is greatly improved.
Description
Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a cage-type microbial carrier immobilized biochemical tank. Background technique [0002] In sewage (waste) water treatment, biochemical processes are more common; in order to improve the treatment effect of biochemical processes, microorganism carriers are added to the biochemical pond. At present, the common ones are contact oxidation tank, MBBR (moving bed biofilm reactor) and so on. [0003] However, the microbial carrier in the contact oxidation tank process is uniformly fixed at the bottom of the tank, but it is difficult to repair the microbial carrier after damage. The MBBR process microbial carrier (MBBR filler) tends to accumulate at the water outlet along with the water flow, and the microbial carrier (MBBR filler) is unevenly distributed in the pool and easily causes the water outlet to be blocked. Summary of the invention [0004] In view of the defects in the pri...
