  The breeding water circulation type land farming device described in the above-mentioned Patent Document 1 connects the breeding water tank, the biological treatment device and the ozone purification device with a pipe in order to form a circulation path, and continuously feeds the breeding water in the breeding water tank. It is comprised so that a purification process may be carried out.

  The seafood aquaculture system described in Patent Document 2 connects an aquarium and a plurality of filtration tanks with a piping system, a circulation pump and a water temperature regulator are provided in the piping system, and is provided at one end of the piping system. The suction port is connected to the bottom of the water tank, and the other end is connected to a water pipe provided on the top of the water tank. Moreover, the bottom part of the said water tank is provided with the bottom nozzle connected to the submersible pump, and it is comprised so that a circulation may arise in a water tank by the said water spray pipe and the said bottom part nozzle.

  The conventional breeding water purification apparatus requires a very large filtration tank as compared with the volume of the breeding tank. For this reason, the apparatus became large and required a large space for installing the filtration tank separately from the breeding tank.

  On the other hand, in order to sufficiently clean the breeding water, it is necessary to provide a plurality of filtration chambers or filtration devices so that they can be repeatedly filtered. However, in the conventional purification apparatus, since a plurality of filtration chambers or filtration apparatuses are connected via piping, the apparatus becomes even larger. Moreover, since a long piping system is used, a circulation pump with a large output is required.

  Moreover, although the breeding water is forced to circulate in the aquarium, the breeding water in the circular or oval aquarium is merely flowed, so that the flow velocity in the aquarium varies greatly depending on the location. For this reason, it cannot be said that it is suitable for breeding fish to be migrated.

  The present invention has been conceived under the circumstances described above, solves the above-mentioned conventional problems, can reduce the size of the filtration tank, and enhances the filtration performance to filter the breeding water over a long period of time. An object of the present invention is to provide a breeding water purification device that can be used, a breeding water tank using the breeding water purification method, and a breeding water purification method.

  The breeding water purifying apparatus according to the invention described in claim 1 of the present application has a plurality of filtration chambers filled with filter media arranged in a line in a substantially horizontal direction, and a communication portion for allowing breeding water to flow into adjacent filtration chambers. In addition to providing a filtration tank for performing filtration while allowing breeding water to flow in the vertical direction by alternately providing the filtration chamber at the top and bottom of each filtration chamber, and a circulating flow generating means for circulating the breeding water, the filtration tank is installed. A water tank, a circulation circuit for returning filtered water flowing out from the filtration tank into the water tank by a circulation pump, water temperature adjusting means for setting the breeding water circulating in the tank to a predetermined temperature, and sterilizing the breeding water And sterilizing means.

  The kind of breeding water to be purified by the purification apparatus according to the present invention is not particularly limited and can be applied to both seawater and fresh water. Conventionally, a large apparatus has been required for the purification of seawater. However, downsizing can be achieved by applying the present invention. In addition, the kind of organisms to be bred using the breeding water is not particularly limited, and not only marine or marshy seafood but also plants such as seaweed can be bred.

  Moreover, the water tank in the purification apparatus according to the present invention can be used as a breeding water tank, or the above purification apparatus can be used only for the purpose of filtering the breeding water, and a living organism can be raised in a separately provided breeding water tank.

  The filtration tank according to the present invention is configured by arranging a plurality of filtration chambers in a row in a substantially horizontal direction. The form and size of each filtration chamber are not particularly limited. By alternately providing communication portions for allowing breeding water to flow in adjacent filtration chambers at the top and bottom of each filtration chamber, there is no need to provide upper and lower pipes for flowing the breeding water to each filtration tank. Moreover, if the opening part provided in the wall part which partitions off each filtration chamber is made into a communication part, piping itself will become unnecessary. For this reason, it becomes possible to set the space between each filtration chamber small. In addition, the apparatus can be reduced in size.

  For example, a plurality of filtration chambers are continuously configured by providing a plurality of partition plates at predetermined intervals so that a long water channel having a rectangular cross section is formed alternately with upper and lower communication portions. Can do. By providing the communication part alternately at the top and bottom of each filtration chamber, the breeding water is filtered while flowing in the vertical direction in the filtration tank. Thereby, it becomes possible to install a multistage filtration tank in a small space.

  Although the form of the water tank is not particularly limited, it is preferable to employ a water tank in which the breeding water is not retained when the circulation is generated and the breeding water in the tank can be smoothly circulated. For example, a water tank having a circular shape, an elliptical shape, a donut shape, or the like can be employed.

  The said circulation circuit is a circuit for returning the filtered water which flowed out from the filtration tank to a water tank, and is comprised so that filtered water may be returned to a breeding water tank by a circulation pump etc. The water intake of the circulation circuit is provided at the end of the filtration tank. On the other hand, the discharge port of the circulation circuit can be provided on the inner wall of the water tank. The said circulation circuit can also be installed in a water tank, and can also be installed in the outer side of a water tank.

  In addition, as in the invention described in claim 8, the circulating flow generating means is configured by providing a jet nozzle that mixes air into the filtered water discharged from the circulation circuit and jets it in the flow direction of the breeding water. Can do.

  By generating the above-described circulation with the filtered water ejected from the ejection nozzle, it is possible to disperse and float wastes, seafood excrement and the like in the breeding water. Thereby, it is possible to prevent seafood excrement and the like from accumulating at a specific site. In addition, it is possible to efficiently filter the breeding water by allowing the excrement and the like to smoothly flow into the filtration tank using the circulation.

  Various devices can be adopted as the water temperature adjusting means. Moreover, the site | part which provides a water temperature control means is not specifically limited, either. It is possible to adjust the temperature of the breeding water directly by installing a heater etc. in the tank, or by adjusting the temperature of the filtered water by installing it in the circulation circuit. You can also

  The sterilizing means is not particularly limited, and various apparatuses can be employed. For example, it is preferable to employ the ozone generator described in claim 9. Although the site | part which provides the said sterilizer is also not limited, It is preferable to comprise so that ozone may be added to filtered water in the said circulation circuit, and it may return to a water tank.

  The invention described in claim 2 of the present application is configured such that the filtration tank is installed in a central portion of the water tank, and breeding water is circulated around the filtration tank.

  By installing the filtration tank in the center of the water tank, it is not necessary to separately set a space for installing the filtration tank, and the installation space for the purification device can be greatly reduced. In addition, since a continuous annular flow path for circulating the breeding water can be formed around the filtration tank, it is possible to generate a smooth circulation with little change in flow velocity.

  Moreover, when providing the said filtration tank in a water tank, like the invention described in Claim 3, while installing the water intake of the said filtration tank toward the flow of the breeding water which circulates in the said water tank, the said water tank It is preferable to provide a water intake port for the circulation circuit at the bottom of the circuit.

  When the filtration tank is installed in the center of the water tank and the breeding water is circulated around the filtration tank, the flow velocity in the vicinity of the filtration tank becomes the smallest. For this reason, floating substances, such as garbage in breeding water, are collected around the filtration tank. If the intake port of the filtration tank is set so as to face the flow of breeding water, the accumulated suspended matter or the like can be easily flowed into the filtration tank. The suspended matter or the like flowing into the filtration tank is filtered by the filter or decomposed in the filter. In addition, the position which provides the said water intake is not specifically limited. The breeding water in the aquarium can be overflowed, and water can be taken into the filtration tank, or can be introduced into the filtration tank from near the bottom of the aquarium. Moreover, it can also comprise so that filtered water may flow in from the whole depth direction area of a water tank.

  By adopting the above configuration, it is possible not only to smoothly feed the breeding water into the filtration tank, but also to filter suspended matters in the breeding water extremely efficiently.

  The filter medium filled in each filtration chamber is not particularly limited. Each filter chamber can be filled with a different filter medium, or, as in the invention described in claim 7, the filter mediums formed of different materials can be stacked in the vertical direction and filled in each filter chamber. it can.

  That is, the height of the upper communication portion is set so that the water level in each of the filtration chambers decreases stepwise from the level of the breeding water migrating in the water tank toward the intake port of the circulation circuit. Thereby, the breeding water in the filtration tank flows through the filtration tank by gravity and is filtered, and flows into the intake port of the circulation circuit.

  The form and function of the upper communication part are not particularly limited. For example, the communication portion can be configured as a weir that opens toward the adjacent filtration chamber, and the breeding water can flow to the adjacent filtration chamber so as to overflow from the communication portion. On the other hand, it is preferable that the breeding water flows easily to the communicating portion at the bottom via a water-permeable mat or the like.

  By employ | adopting the said structure, it becomes possible to make a filter medium act on filtered water efficiently. Moreover, since the flow by gravity is utilized, a big force does not act on a filter medium. Therefore, various filter media can be employed without fear of the filter media being damaged by pressure or the like.

  As in the invention described in claim 5, a plurality of the filtration chambers are arranged in a line in a substantially arc shape along the circulation direction of the breeding water or in a substantially spiral shape toward the center of the water tank, and the filtration tank is arranged. Can be configured.

  The filtration tank according to the present invention is configured by forming a plurality of filtration chambers in a row. For this reason, the said filtration tank can be formed in the substantially circular arc shape or substantially helical shape in alignment with the circulation direction of breeding water. Even if the filtration tank of the said form is installed in a water tank, it cannot hold | maintain the circulation of breeding water, and can maintain the stable circulation.

  Moreover, like the invention described in claim 6, a plurality of spiral or spiral filtration tanks combined with each other can be provided.

  For example, by arranging two spiral filtration tanks in combination in a double spiral shape, it is possible to install a filtration tank capable of treating a large amount of breeding water with high accuracy in a small space.

  In the invention described in claim 10 of the present application, a filtration tank is installed in the center, a tank filled with breeding water, a circulation generating means for generating a circulation of the breeding water around the filtration tank, and the above Sterilizing means for sterilizing the breeding water, temperature adjusting means for regulating the temperature of the breeding water, and a circulation circuit for returning the filtered water flowing out from the filtration tank to the breeding water by a circulation pump. It relates to breeding tanks. In the filtration tank, a plurality of filtration chambers filled with a filter medium are arranged in a row in a substantially horizontal direction, and communication portions for flowing breeding water to adjacent filtration chambers are alternately arranged at the top and bottom of each filtration chamber. It is provided and configured to perform filtration while allowing breeding water to flow in the vertical direction.

  In this invention, since a filtration tank can be set small compared with the volume of a breeding aquarium, the circulation area | region of the breeding water around the said filtration tank can be utilized as a breeding aquarium.

  The invention described in claim 11 of the present application is such that the intake port of the filtration tank is installed toward the flow of the breeding water circulating, and the intake port of the circulation circuit is provided at the bottom of the breeding water tank. is there.

  The invention described in claim 12 of the present application employs an ozone generator as the sterilizing means. The output and method of the ozone generator are not particularly limited, and various conventional devices can be employed.

  The invention described in claim 13 of the present application is provided with a fishing pole on which an angler can be placed above the filter tank. This is suitable when the breeding water tank according to the present invention is used as a fishing pond.

  In the present invention, since the filtration tank is installed in the center of the water tank, the circulation area of the breeding water around the filtration tank can be divided into inner and outer breeding areas by a wire net or the like without impairing the circulation. . And, by cultivating different types of seafood in these divided areas and configured to catch the seafood in the breeding area provided on the inner side from the fishing platform, an unprecedented fishing pond can be provided.
