This is the treated water outflow part that constitutes the piping system that circulates water in the aquarium where fish are kept.

Conventionally, fish farming equipment using an aquarium is equipped with an aquarium (not shown) for raising fish, and a piping system for circulating water in the aquarium is equipped with a circulating water pump (not shown) and a water pump (not shown) as shown in Fig. 5. A filtration device is installed.

[Problem to be solved by the invention] In the above-mentioned conventional technology shown in FIG. 5, in order to improve the purification efficiency of circulating water, that is, breeding water, it is necessary to consider the type of filter material 2 to be filled in the filtration device main body 1A. , an aeration device 4 is provided to increase the contact efficiency between the circulating water and the filter material.

In other words, in general, the biggest growth-inhibiting factor in fish breeding is the generation of ammonia and organic matter in the breeding water, and conventional methods of removing ammonia and organic matter have mainly been carried out using the biofilm method. . In this biofilm method, a filter material 2 with a large surface area and high porosity is filled into the filter main body 1A, and purification microorganisms are attached and grown on the filter material 2, and purification is carried out by bringing the material into efficient contact with culture water. It was hot.

However, in the conventional device shown in FIG.
is filled in the filter main body 1A and immersed in water, and no particular consideration was given to the inner wall surface of the filter.

The present invention was made to solve the problems of the conventional technology described above, and effectively utilizes the inner wall surface of the filtration device body to increase the storage capacity of the filtration material, increase the adhesion area for purifying microorganisms, and improve the circulation of the circulating water. The purpose of the present invention is to provide a filtration device for fish farming that can improve the purification efficiency of (breeding water).

[Means for Solving the Problems] In order to achieve the above object, the configuration of the fish farming filtration device according to the present invention is such that the filtration device body is installed in a piping system that circulates water in an aquarium for breeding fish, and In a filtration device for fish farming, which has a raw water inlet on one side and a treated water outlet on the other, and is equipped with a means for stirring circulating water flowing through the container, an inner wall surface of the filtration device main body is provided with: A filter material to be fixed,
A filtration material is provided which is filled into the filtration device body and immersed in water to increase the surface area to which purified microorganisms adhere.

[Operation] The operation of the above technical means is as follows.

That is, by fixing the filter material to the inner wall surface of the filtration device main body, the wall surface is effectively utilized, and the filter material filled in the filtration device main body and immersed in water and the filter material fixed to the inner wall surface are used to purify microorganisms. Ammonia, which is a factor that inhibits the growth of fish, increases the surface area on which it adheres and increases the purification efficiency of circulating water (rearing water).
Organic matter can be sufficiently removed.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a configuration diagram of a fish farming filtration device according to an embodiment of the present invention, FIG. 2 is a partially cutaway perspective view showing the filter material on the inner wall surface of the filtration device main body container of FIG. 1, and FIG. The figure is an enlarged cross-sectional view of the filtering material fixing portion on the inner wall surface of the filtering device, and FIG. 4 is a front view showing the fixing means for the filtering material. In FIG. 1, parts with the same reference numerals as those in FIG. 5 are the same parts as in the prior art, so their explanation will be omitted. Also, the solid line arrow in Figure 1 is
It shows the flow of water within the filtration device.

In FIGS. 1 to 3, 1 is the filter main body constituting the container of the filter tank, 1a is the inner wall surface of the filter main body (hereinafter simply referred to as the filter inner wall surface), and 2a is
The filter material 2b filled in the filter main body 1 and immersed in water is a filter material fixed to the inner wall surface 1a of the filter device.

The filter medium 2 (general term for 2a, 2b) is generally preferably one with a large surface area and high porosity, such as a fabric,
There are various types such as filter paper, plastic, metal mesh filters, and porous materials, but in this example, a string-like material made of vinylidene chloride was used.
An example of the shape of the filter material formed from the string-like material is shown in an enlarged scale in FIG.

As shown in FIG.
For example, a supporting material 6 such as stainless steel is attached to the filter main body 1.
It is attached to the inner and inner wall surfaces 1a, and the filter material 2 is fixed thereto using a binding band 7 or the like.

The filter material 2a for filling is used by being attached to supporting materials arranged in the filter main body 1 in a dense manner as shown in FIG. 1, and immersed in water. Similarly, the filter material 2b for fixing to the wall surface is fixed to the wall surface as shown in FIG. 2 via a support member attached along the inner wall surface 1a.

Next, the operation of such a fish farming filtration device will be explained.

Water in an aquarium (not shown) for breeding fish, ie, breeding water, is circulated through the piping system by a circulating water pump (not shown). The circulating water (breeding water) that has flowed into the filter main body 1 from the raw water inlet 3 is agitated by the bubbles generated by the aeration device 4, and is mixed with the filter material 2a filled in the filter and the inner wall surface 1a of the filter.
Ammonia oxidizing bacteria, nitrite oxidizing bacteria, and other purifying microorganisms adhere to and grow in a film on the surface of the filter material, and by efficiently contacting the culture water, the ammonia in the culture water is removed. ,
Organic matter can be removed.

The purified water returns to the water tank from the treated water outlet 5 via the piping system, and is circulated thereafter.

In this embodiment, the surface area on which the purifying microorganisms adhere is made larger than before with the filter material 2a for filling and the filter material 2b for adhering to the inner wall surface, so that the purification efficiency is improved and ammonia, which is a growth inhibiting factor in fish breeding, is removed. , organic matter can be removed sufficiently.

In addition, although the above-mentioned example showed the example which used the string-like filter material, this invention is not limited to this, and it does not interfere even if other types of filter materials are used.

Further, in the above embodiment, the support material 6 and the binding band 7 are used as means for fixing the filter material to the inner wall surface of the filter device.
Although the present invention is not limited to this example, adhesive may be used for bonding.

[Effects of the invention] As explained in detail above, according to the invention, the inner wall surface of the filtration device body is effectively used to increase the storage of the filter material, increase the adhesion area of purifying microorganisms, and improve the circulation water.
