Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a holder for a granular bacterial cell immobilization carrier, and in particular, the present invention relates to a holder shaped in the middle of a cylindrical double tube. The present invention relates to a holder that fills a gap formed with a granular microbial cell immobilization carrier.

0002

[Conventional technology]

Conventionally, holders for granular bacterial cell immobilization carriers were made by attaching wire mesh to each double cylindrical frame. It was often used in an upright position.

0003

[Problem that the idea aims to solve]

However, in the above method, granular bacteria are fixed in the gap formed in the middle of the double tube. When the carrier is filled, the wire mesh swells due to the weight of the carrier and is formed in the middle of the double tube. In some cases, the gaps between the carriers become non-uniform and the performance of the carrier cannot be maintained sufficiently.

0004 In addition, the carrier blocked the wire mesh, making it difficult to supply air to the carrier. This made it difficult for treated water to penetrate into the carrier.

[0005] Therefore, the present invention provides strength to the double pipe with a simple structure, and reduces the gap between the double pipes to the design value. We provide a holder with a structure that allows the granular microbial cell immobilization carrier to fully utilize its performance. The purpose is to provide

[0006]

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the holder for the granular bacterial cell immobilization carrier of the present invention is made of a cylindrical shape. A holder that fills the gap formed in the middle of a shaped double tube with a granular bacterial cell immobilization carrier. wherein each of the cylindrical double tubes is formed of a helical tube made of a perforated plate. It is characterized by

[0007]

[Effect] As mentioned above, by forming a cylindrical double tube with a helical tube using a perforated plate, , the strength is increased, and the width of the gap formed in the middle can be secured as designed.

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0009] The holder 1 of the granular bacterial cell immobilization carrier is made by spirally forming a perforated plate 3 in which many long holes 2 are formed. It consists of a double-walled helical tube 4, and the upper and lower ends of the inner tube 5 are each An outward facing tongue piece 5a and an inward facing tongue piece 6a are attached to both ends of the outer tube 6, respectively. At the upper and lower ends of the inner tube 5 and outer tube 6, there are rings to maintain the gap S between the two tubes at a predetermined size. A ring-shaped upper lid 7 and a lower lid 8 are provided.

0010 Further, the cage 1 is installed on a support stand 9, and is inserted into the cage 1 by penetrating the support stand 9. An air pipe 10 for supplying air is provided.

[0011] When such a retainer 1 is used in a wastewater treatment device, there is a gap between the inner pipe 5 and the outer pipe 6. The cage 1 filled with the granular bacterial cell immobilization carrier 11 in the gap S formed is placed on the support stand 9. It is installed in the wastewater treatment tank and holds air through the air pipe 10 connected to the blower. Supplied into container 1. The supplied air becomes bubbles and rises inside the cage 1, which causes As a result, the treated water enters the cage 1 through the long hole 2 and solidifies the bacterial cells filled in the gap S of the double pipe. It is treated by a stabilizing carrier 11.

0012 In the cage 1 as described above, the inner tube 5 and the outer tube 6 are each composed of a helical tube 4. Therefore, it is possible to provide strength, and it is necessary to provide a frame to fix the retainer 1. Even if the gap S is filled with the granular bacterial cell immobilization carrier 11, the inner tube 5 and outer tube 6 will not change. There is no possibility that the long hole 2 will become clogged.

[0013] In addition, sufficient air is supplied to the bacterial cell immobilization carrier 11 from the air pipe 10, and furthermore, Since the water also sufficiently permeates into the bacterial body immobilization carrier 11, the bacterial body immobilization carrier 11 performance can be fully brought out.

[0014] Furthermore, by using the helical tube 4, the diameter and length of the inner tube 5 and outer tube 6 can be freely adjusted. You will be able to choose.

[0015] Note that the cage of this invention is not limited to those that are used in an upright position, and long double pipes can be used. By doing so, it can be used for river purification, and the heirloom pipe can be made into four or six layers. By doing so, the density of the bacterial cell immobilization carrier can also be increased.

[0016]

[Effect of the idea]

As explained above, the granular microbial cell immobilization carrier of the present invention is a spirally wound carrier using a perforated plate. By forming a cylindrical double pipe with pipes, the double pipe has a simple structure and is strong. The gap between the double tubes can be secured as designed, and the granular bacteria can be fixed. The stable performance of the chemical carrier can be maintained.

[0017] In addition, the diameter and length of the double tube can be freely selected, and granular bacterial cells can be The scope of use of immobilization carriers is expanded.
