Problems solved by technology

[0002] In the anaerobic sewage treatment process, the common UASB (upflow anaerobic sludge bed reactor), IC tower, EGSB, etc. adopt the method of bottom water distribution and top water outlet, and the sludge is stirred by the generated anaerobic gas and the upflow water velocity , to achieve the purpose of expanding sludge; however, the distribution of sludge in the reactor is still dominated by the sludge bed that sinks at the bottom, resulting in a small amount of sludge in the upper part of the upflow anaerobic reactor and uneven distribution of sludge , will bring poor water treatment effect

Embodiment approach

[0029] The present application also provides an implementation mode, specifically as follows:

[0030] like figure 2 , image 3 As shown, in this embodiment, the cage-shaped shell is a sphere, which is woven with warp and weft threads; it is divided into two hemispheres, and the two hemispheres are assembled into one body with a connecting piece. The cage-shaped shell combined by buckles can be used to envelop the microbial carrier. The distance between two adjacent weft threads does not exceed the outer diameter of the microbial carrier. Specifically, the diameter of the cage-shaped shell is 1000 mm, and the distance between two adjacent weft threads is 14 mm. The cage-shaped shell provided in this embodiment can envelop the microbial carrier in the cage, for example, the size of the microbial carrier is 20mm*20mm*20mm or 40mm*40mm*40mm.

[0031] The present invention also provides a biochemical pool comprising the cage-shaped microbial filler structure, wherein multiple...

Abstract

The invention discloses a cage-shaped microbial filler structure. The cage-shaped microbial filler structure is characterized by comprising a cage-shaped shell with holes, the cage-shaped shell is filled with a microbial carrier, and the pore diameter of the cage-shaped shell is smaller than the outer diameter of the microbial carrier; the density of the microbial carrier is in gradient distribution, and the density of the microbial carrier is 0.9-1.0 g / cm<3>; and the density of the cage-shaped shell is 0.9-1.0 g / cm<3>. The cage-shaped microbial filler structure is applied to an anaerobic tank, the sludge amount in an anaerobic reactor can be increased, the defect of uneven sludge distribution is overcome, the utilization rate of anaerobic bacteria is increased, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a cage-shaped microbial packing structure and a biochemical pool. Background technique [0002] In the anaerobic sewage treatment process, the common UASB (upflow anaerobic sludge bed reactor), IC tower, EGSB, etc. adopt the method of bottom water distribution and top water outlet, and the sludge is stirred by the generated anaerobic gas and the upflow water velocity , to achieve the purpose of expanding sludge; however, the distribution of sludge in the reactor is still dominated by the sludge bed that sinks at the bottom, resulting in a small amount of sludge in the upper part of the upflow anaerobic reactor and uneven distribution of sludge , will bring poor water treatment effect. Contents of the invention [0003] In view of the defects in the prior art, the present invention provides a cage-shaped microbial filler structure, which can be applied to an anaerobic ...
