Description

The present invention relates to a water quality improving tool for the purpose of improving water quality by floating or submerging on a water surface such as a water treatment tank such as a storage tank or a septic tank, a sea, a river, a lake, a pond, or a swamp.

Conventionally, various water quality improving tools for improving water quality by using minerals, carbon, etc., which are the contents, have been known. As an example, there is Document 1 in which the effect of protecting the contents (silicate minerals) from damage due to impact or friction can be obtained by covering the contents (silicate minerals) with a skeleton portion (carbon material).

The invention according to Document 1 is a lightweight, inexpensive, and easy-to-handle water quality improving tool, and the specific content thereof is a porous material and / or a filler in a skeleton portion forming a water-permeable outer shell. A water quality improving material containing a functional part made of (silicate minerals) is put into a water area such as a river or a lake, a swamp, or a pond to improve the water quality.

And as one of the action effects, the skeleton part has an action of covering the functional part which is the content and protecting it from damage due to impact or friction. That is, when the water quality improving material of the present invention is put into a river, for example, it floats or rolls down the river along with the flow of water, and at that time, it becomes an obstacle such as rocks or stones on the surface or bottom of the river. Although they collide, even in this case, the skeleton protects the contents, so that the contents are not damaged or dissipated.

Japanese Patent Application Laid-Open No. 2003-340482

However, the structure of the skeleton portion of the invention according to Document 1 penetrates a hole instead of a net-like or perforated structure or other net-like material so that water can come into contact with the functional part. However, in the case of such a structure, there may be a problem in shock absorption when a shock is received.

Therefore, the present invention is a case where the impact absorption is enhanced by arranging and forming the carrier and the floating body so as to cover the entire circumference with a rolled substrate made of a long resin band, and an impact is applied from the outside. Also provides a water quality improving tool capable of protecting the carrier and the suspended body covered with the substrate from impact.

The invention of claim 6 is a water quality improving tool capable of improving the water quality by putting it in water and arranging it.
A cylindrical carrier that carries sulfur, a bearing support that is housed in the internal space of the tubular carrier, a bearing support that has buoyancy, a shaft that is inserted through the bearing support and rotatably supported, and a resin band that has thermoplasticity. It is a water quality improving tool characterized by being provided with a substrate which is rolled into a spherical shape having a deformable gap depending on the body and accommodates a bearing support having a buoyancy in the gap.

According to the present invention, when the water quality improving tool is floated in the water to be treated, nitrogen contained in the water to be treated is removed by the denitrification action of sulfur-oxidizing bacteria. In addition, harmful substances are decomposed by the ion exchange action. Then, the shock absorption is enhanced by arranging and forming the carrier supporting sulfur and the floating floating body having buoyancy so as to be covered with a substrate made by rolling a long resin strip, and when a shock is applied from the outside. Even so, the carrier and the floating body covered with the substrate can be protected from the impact. Furthermore, impurities in the water to be treated are adsorbed on the water quality improving tool (fiber body, bag body), and the water to be treated is purified. That is, the water quality is improved by the water quality improving tool (fiber body, bag body) floating on the water surface adsorbing the substance to be adsorbed. Furthermore, since the water quality improving tool itself floats on the water to be treated, it is easy to recover after adsorbing the substance to be treated existing on or in the water surface.

The present invention is a water quality improving tool 1 that improves the water quality of the water to be treated by floating on the surface of the water to be treated or submerged in water. In other words, a bioreactor, that is, a catalyst of a living body such as a microorganism is used. It is a water quality improving tool 1 for the purpose of improving the water quality by decomposing the substances and physically adsorbing harmful substances. The water to be treated is assumed to be a storage tank, a reservoir, a river, a water to be treated, etc. existing in the sea, which is temporarily stored.

The water quality improving tool 1 of the present invention can be roughly classified into the first embodiment and the second embodiment. Hereinafter, each embodiment will be described.

The main constituent article of the water quality improving tool of the first embodiment shown in FIG. 2 is mainly composed of a carrier 10, a floating body 13, a substrate 20, a fiber body 30, a bag body 40 and the like. Hereinafter, each of these constituent articles will be described.

The carrier 10 supports sulfur 5, and may be any material, shape, and size as long as it can support sulfur 5. Therefore, various materials can be used, for example, resin, metal, and the like can be used. As the shape, for example, a sphere, a cube, a rectangular parallelepiped, a cylinder, or the like can be considered. Further, as will be described later, the carrier 10 will be accommodated in the gap 22 inside the substrate.

Examples of the carrier 10 using a resin (resin carrier 10) include, as shown in FIG. 1, a spherical shape obtained by combining a plurality of resin annular bands 11. The resin annular band 11 is formed by connecting the ends of a flat band-shaped polypropylene band (PP band) or a flat band-shaped polyester band (PET band) to form an annular shape, and a plurality of the annular bands are combined as a whole. It is formed in the shape of a single sphere. For example, one spherical shape can be formed by combining the resin annular band 11 in the vertical direction, the horizontal direction, the diagonal direction, and the like. The length, width, thickness, combination, etc. of the resin annular band 11 itself may be limited as long as the spherical shape can be maintained by the plurality of annular resin bands. For example, it is conceivable that the annular band has a width of about 1 cm to 2 cm and the diameter of the sphere combined with the annular band is about 5 cm to 10 cm.

Although not shown, examples of the carrier 10 using metal (metal carrier 10) include those in which a wire mesh having a predetermined mesh is formed into a spherical shape or the like. That is, the carrier 10 can be a mesh-like sphere using a wire mesh. In addition, the carrier 10 may have a spherical shape or the like using a resin net having a predetermined mesh. The overall size and mesh size do not matter.

As for other shapes, a mesh-shaped cylindrical body as in other embodiments described later can be considered, and in this case, either a bottomed cylinder or a bottomless cylinder may be used. The size is not limited, but for example, a total length of about 10 cm can be considered.

It is desirable that the carrier 10 has a water passage space (gap 12) through which water can pass. Specifically, in the above-mentioned resin carrier 10 formed in a spherical shape by combining a plurality of resin annular bands 11 in a vertical direction, a horizontal direction, an oblique direction, etc., the resin annular band 11 and the resin are made. The space between the annular zone 11 and the annular zone 11 (gap 12) is a water passage space. Further, when a wire mesh or a resin mesh having a predetermined mesh is used as a carrier, the mesh becomes a water passage space.

In addition, the carrier 10 having no water passage space may be used. Therefore, waste shells, sponges, spheres (balls), various waste materials, and the like that do not have a water passage space can be used as carriers. Although not shown, these will also be described below.

Examples of the waste shells include oysters, scallops, pearl oysters (pearl oysters) discharged from household waste and seafood factories, and these waste shells can be used as carriers. Any kind of shell can be used as the type of waste shell, but in particular, oysters have a shape with irregularities on the surface, so that sulfur and sulfur-oxidizing bacteria are likely to adhere to them. As described above, if the used shell is to be discarded, it is possible to provide the water quality improving tool 1 that meets the recent demand for global environmental protection.

A sponge (foam) can also be used as the carrier 10. Examples of the sponge include a natural sponge and a urethane sponge. The material of this foam is not particularly limited and may be any material. Specific examples thereof include foams such as foamed polypropylene, foamed polyethylene, foamed ABS, foamed urethane, and foamed styrene. Of these, only one type may be used, or two or more types may be used in combination. Furthermore, the shape of the foam is not particularly limited. Since the foam can be easily cut into a predetermined shape, it can be applied to any suitable shape. Specifically, for example, any shape such as a spherical shape, a triangular shape, a square shape, a cylindrical shape, a plate shape, and a rod shape can be used.

When the sphere (ball) is used as the carrier 10, a tennis ball or the like used in various ball games can be used. In particular, if a sphere (ball) having buoyancy is used, it floats in the water to be treated, so that it can be suitably used. In particular, a used sphere (ball) to be discarded is desirable.

Further, a used PET bottle, a steel can, or the like can be used as the carrier 10. In particular, in the case of a PET bottle, closing the lid creates buoyancy in the PET bottle itself, which is suitable because it floats in the water to be treated.

As other waste materials, it is conceivable to use waste plastics, used clothes, waste wood and the like as the carrier 10. Since buoyancy is generated in waste plastic, waste wood, etc., it is suitable because it floats in the water to be treated.

As described above, if the used waste material is to be discarded, it is possible to provide the water quality improving tool 1 that meets the recent demand for global environmental protection.

As described above, the carrier 10 carries sulfur 5, specifically, sulfur-oxidizing bacteria (photosynthetic bacteria), and the treated water passes through the carrier 10 carrying the sulfur-oxidizing bacteria to cause sulfur-oxidizing bacteria. The denitrifying action removes nitrogen contained in the water to be treated. In addition, harmful substances are decomposed by the ion exchange action. In addition, when it is used as drinking water in which minerals dissolve into water, the taste is improved, and further, the effect of supplementing calcium can be expected.

The photosynthetic bacteria are mainly purple sulfur bacteria and green sulfur bacteria, but are not limited thereto. As an example of the method of adhering sulfur bacteria to the carrier 10, a method of putting flowable sulfur in a container and immersing the carrier 10 in the flowable sulfur 5 in the container can be mentioned.

In the present invention, since the water quality improving tool 1 of the first embodiment is suspended by the floating body 13 housed in the gap 22 inside the substrate 20, the floating body 13 itself is made of a material that floats in water. Therefore, the floating body 13 may be made of any material as long as it has buoyancy. As the material, a foamable material is desirable, and examples thereof include foamed plastic. Further, it may be fiber reinforced plastic (FRP) or the like. In addition, the buoyancy may be increased by providing an air chamber inside the floating body 13. Since the shape and size are not limited, for example, a spherical shape (foaming sphere) having a diameter of about 5 to 6 mm can be mentioned.

The substrate of the first embodiment is formed by rolling a resin strip 21 having thermoplasticity into a spherical shape having a plurality of deformable gaps 22 inside. The specific shape is preferably a sphere as shown in FIG. 2, but may be a substantially cube, a substantially rectangular parallelepiped, a cylinder, or the like.

The material of the substrate 20 may be any material as long as it is made of a resin having thermoplasticity and can be rolled. Therefore, a heat-flexible binding band, for example, a flat band-shaped polypropylene band (PP band), a flat band-shaped polyester band (PET band), or the like can be used.

A commercially available resin band 21 in which a PP band having a width of about 1.5 cm is incised to an appropriate width can be used. The resin strip 21 constituting the substrate 20 is preferably having a width of about 3 mm to about 5 mm, but is not limited to this width. Further, the thickness may be any thickness as long as it can be rolled. Specifically, a thickness of about 0.2 mm to about 0.9 mm can be considered.

The surface of the resin strip 21 may be provided with a convex portion. By providing this convex portion, it has a non-slip function and can firmly hold the carrier 10 and the floating body 13. Examples of the convex portion include a dot-shaped one and a linear one.

The substrate 20 can be easily formed into a spherical shape by applying heat to the long resin strip 21 and rolling it. Hereinafter, the molding method will be briefly described.

First, a long resin strip 21 is spirally wound around a metal cylinder such as a pipe, and heat is applied to the cylinder to give the resin strip 21 a tubular shape. Next, the resin strip 21 that has been habituated into a tubular shape is removed from the tubular body and molded into a spherical shape while retaining heat. This molding may be formed by pushing it into a forming device such as a sphere. Then, by cooling for a certain period of time, the resin strip 21 is solidified into a spherical shape as a whole, and is completed as a substrate. As for cooling, a method such as contacting with air to cool naturally or immersing in cooling water can be considered.

The fiber body 30 is made of water-absorbent fibers and / or ultrafine fibers. Examples of the material of the fiber body 30 include polyester fiber, polyester, nylon blended fiber, cotton and the like. Hazardous substances floating on the water surface or in water are physically adsorbed on the fiber body 30, and the water quality is improved.

As the water-absorbent fiber, an acrylic acid polymer partially sodium salt crosslinked product or the like, which is a highly water-absorbent resin such as a water-retaining material, can be used. Commercially available products may be used. For example, Lanseal (registered trademark) and the like can be mentioned.

As the ultrafine fiber, for example, polyvinylidene chloride-based synthetic fiber melt-spun from a copolymer containing vinylidene chloride as a main component can be used. Commercially available products may be used. For example, Saran (registered trademark) and the like can be mentioned. In addition, it may be a long fishing line. Examples of the material of the fishing line include nylon (polyamide-based synthetic fiber), fluorocarbon (polyvinylidene fluoride), and a twisted polyethylene fiber.

Regarding the arrangement of the fiber body 30, examples thereof include an arrangement in which the substrate is covered with water-absorbent fibers so as to cover the entire circumference of the substrate, and the substrate covered with the water-absorbent fibers is wound with ultrafine fibers. In addition, an arrangement in which the water-absorbent fiber and the ultrafine fiber are mixed and the substrate is covered with the mixed water-absorbent fiber and the ultrafine fiber can be mentioned.

The bag body 40 is formed in the shape of a mesh bag by knitting fibers 40a such as yarns. That is, it has a mesh shape with a certain mesh and a bag shape that can accommodate the contents. Examples of the material of the yarn include synthetic fibers such as polyester and polyamide, natural fibers such as wool, and recycled fibers such as rayon. The thickness, entanglement method, etc. can be appropriately selected. Hazardous substances floating on the water surface or in the water are physically adsorbed on the bag body 40, and the water quality is improved.

The bag body 40 is mainly in the shape of a bag having a bottom and an opening, and may have any size and shape as long as it can accommodate the substrate 20 and the like. In addition to the size that can accommodate one substrate 20 and the like, when two or more substrates 20 and the like are accommodated, the size is naturally such that two or more substrates 20 and the like can be accommodated side by side. Therefore, the size of the bag 40 can be arbitrarily changed depending on the number of substrates and the like.

When a plurality of water quality improving tools 1 are housed in a row at intervals in the longitudinal direction in one long bag body 40, the long bag body 40 is located between the water quality improving tool 1 and the water quality improving tool 1. A narrowed portion (joint portion) may occur, and the water quality improving tool 1 and the water quality improving tool 1 move separately depending on this joint portion. Therefore, the effect of the present invention can be more effectively achieved.

A string may be passed through the opening 40d of the bag body 40 to form a purse. By doing so, after the water quality improving tool 1 is housed in the bag body, the opening 40d can be squeezed with a string to prevent the water quality improving tool 1 from coming out of the bag body 40.

It is desirable that the carbon fiber 42 having conductivity is woven into the fiber 40a of the bag 40. Examples of the carbon fiber body 42 include PAN-based carbon fibers and pitch-based carbon fibers.

Microorganisms and impurities in the water are attached by the carbon fiber body 42, and the water is purified by these microorganisms. Specifically, since the carbon fiber 42 has less negative charge than other fibers, microorganisms are easily adsorbed on the carbon fiber 42, and the microorganisms adsorbed on the carbon fiber 42 decompose organic substances. The water quality is improved.

Next, the arrangement configuration of the carrier 10, the floating body 13, the substrate 20, the fiber body 30, and the bag body 40, which are the constituent articles of the water quality improving tool 1 of the first embodiment, will be described.

The carrier 10 and the floating body 13 are housed in the gap 22 of the substrate 20. As described above, the substrate 10 is formed by rolling the thermoplastic resin strip 21 into a spherical shape having a plurality of deformable gaps 22 inside, and the carrier 10 and the floating body 13 are formed in the gaps 22. (See Fig. 2). The reason why the gap 22 is deformable is that the resin strip constituting the substrate 10 bends, so that the gap 22 can also be deformed. As described above, the shape and size of the gap 22 can be appropriately deformed, and the carrier 10 and the floating body 13 are accommodated (filled) in the plurality of gaps 22.

Since the number of the carrier 10 and the floating body 13 is not limited, one or a plurality of the carrier 10 and the floating body 13 are accommodated. Since the ratio of the carrier 10 and the floating body 13 may be any ratio, they can be appropriately adjusted and used.

Next, the substrate 20 containing the carrier 10 and the floating body 13 is covered with the fiber body 30 (see FIG. 2 and the like), and as described above, the substrate 20 is covered with water-absorbent fibers so as to cover the entire circumference of the substrate 20. Then, the substrate covered with the water-absorbent fiber may be wound with the ultrafine fiber, or the substrate 20 may be covered with the water-absorbent fiber and the ultrafine fiber mixed. In order to prevent the carrier 10 and the floating body 13 from being released from the inside of the water quality improving tool 1, it is desirable to take measures such as increasing the amount of fibers in the fiber body 30 and making the fibers finer.

Then, the substrate 20 thus covered with the fiber body 30 is housed in the bag body 40 (see FIG. 2). That is, the substrate 20 covered with the fiber body 30 as the content is accommodated by the bag body formed by weaving the fibers into a mesh-like bag shape.

As described above, the fiber body 30 and the substrate 20 are arranged and configured from the outermost bag body 40 to the inside in order, and the carrier 10 and the floating body 13 are arranged and configured in the substrate 20.

The main constituent article of the water quality improving tool 1 of the second embodiment shown in FIG. 3 is mainly composed of a carrier 10, a floating body 13, a composite substrate 25, and the like. Hereinafter, each of these constituent articles will be described.

Since the carrier 10 and the floating body 13 of the second embodiment are the same as the carrier 10 and the floating body 13 described in the first embodiment, the description thereof will be omitted. The composite substrate 25 of Example 2 includes a resin band 21 having thermoplasticity, a fiber body 30 made of water-absorbent fibers and / or ultrafine fibers, and a conductive fiber body 47 and / or a carbon fiber body 42 having conductivity. , Are entangled and have a deformable gap 22 inside, and are formed by rolling into a spherical shape as a whole. Of these, the resin strip 21 is the same as the substrate 20 of Example 1. Further, since the fiber body 30 and the conductive carbon fiber body 42 are the same as those in the first embodiment, the description thereof will be omitted. The second embodiment can also include the bag body 40, but since the bag body 40 is the same as the bag body 40 of the first embodiment, the description thereof will be omitted.

A conductive fiber body 47 having conductivity such as iron, copper, or stainless steel having a high iron content is provided. The conductive fiber body 47 is made by processing iron, copper, stainless steel having a high iron content, or the like into fine fibers. The fineness of the conductive fiber is preferably less than 1 mm.

Next, the arrangement configuration of the carrier 10, the floating body 13, the composite substrate 25, etc., which are the constituent articles of the water quality improving tool 1 of the second embodiment, will be described.

In the second embodiment, the resin strip 21 having thermoplasticity, the fiber body 30 made of water-absorbent fibers and / or ultrafine fibers, and the conductive fiber body 47 and / or the carbon fiber body 42 having conductivity are entangled. Then, it is rolled into a spherical shape to form a composite substrate 25 (spherical shape). Of these, since the resin strip 21 is the same as the substrate of the first embodiment as described above, it is formed by the same method as the substrate 10 (spherical) of the first embodiment and serves as a base of the composite substrate 25. It is a thing.

The resin band 21 is entangled with a fiber body 30 made of water-absorbent fibers and / or ultrafine fibers, and a conductive fiber body 47 and / or a carbon fiber body 42 having conductivity, but is spherical as a whole. .. The composite substrate 25 has a plurality of deformable gaps 27, and the carrier 10 and the floating body 13 are housed (filled) in these gaps 27. The point that the shape, size, and the like of the gap 27 can be appropriately deformed is for the same reason as described in the first embodiment.

No matter how the resin strip 21 constituting the composite substrate 25, the fiber body 30 made of water-absorbent fibers and / or ultrafine fibers, the conductive conductive fiber body 47 and / or the carbon fiber body 42 having conductivity are entangled with each other. Alternatively, each constituent article may be used multiple times to cover it. For example, a spherically rolled resin strip 21 (spherical shape) in which the carrier 10 and the floating body 13 are housed is covered with the fiber body 30, and another resin strip 21, the fibrous body 30, and the conductive fiber are placed on the fiber strip 30. A composite in which the body 47 is entwined and then covered with a wide-area strip-shaped carbon fiber 42 and a resin strip 21 entwined to form a spherical shape as a whole. The structure of the base 52 may be used.

Further, the composite substrate 52 thus formed may be housed in the bag body 40. That is, the composite substrate 25, which is the content, can be accommodated by the bag body 40 formed in the shape of a mesh bag by knitting fibers.

The size of the water quality improving tool 1 of the first embodiment and the second embodiment is not limited, but for example, one having a diameter of about 100 mm to about 550 mm can be considered.

The resin strip 21 of the first embodiment, the resin strip 21 of the composite substrate 52 of the second embodiment, and the floating body 13 have a structure in which conductive carbon powder or graphite powder 46 is attached. (See FIG. 5).

Although not shown, the material of the carbon powder is, for example, carbonized wood, carbonized bamboo, carbonized pine bark, carbonized rope (made of chemical fiber or natural fiber), or pulverized carbonized fiber. Alternatively, it may be a mixture, but any carbon powder having conductivity may be used. In addition, carbonized rice husks and the like may be used. Then, as will be described later, carbonized wood, bamboo, pine needles, ropes, fibers and the like are once made into powder and adhered to the floating body 13 and / or the resin strip 21.

Examples of carbonized wood include solid wood such as sugi and cypress, and small pieces such as laminated lumber, laminated lumber, plywood, and various boards. Examples of the carbonized bamboo include matake, Moso bamboo, light bamboo, female bamboo, black bamboo, and bamboo bamboo. Examples of the carbonized rope include those made by twisting plant fibers such as hemp and straw and chemical fibers. Examples of carbonized fibers include natural fibers such as cotton, linen, wool and silk, and rayon which is a synthetic fiber.

A binder is used to attach the carbon (carbon) powder or graphite (graphite) powder 46 to the floating body 13 and / or the resin strip 21. Examples of the binder include funori and the like. Specifically, a binder is immersed in the floating body 13 or the substrate 10, and carbon powder or graphite powder 46 is applied to the floating body 13 or the resin strip 21 in which the binder is immersed. Attach by grinding.
According to the configuration provided with carbon (carbon) powder or graphite (graphite) powder 46, the negative ion generation effect and the sewage purification effect are enhanced by the conductive carbon (carbon) powder or graphite (graphite) powder. Can be expected.

When the water quality improving tool 1 is floated in the water to be treated, nitrogen contained in the water to be treated is removed by the denitrification action of sulfur-oxidizing bacteria. In addition, harmful substances are decomposed by the ion exchange action. Further, impurities in the water to be treated are adsorbed on the water quality improving tool 1 (fiber body 30, bag body 40), and the water to be treated is purified. That is, the water quality is improved by the water quality improving tool 1 (fiber body 30, bag body 40) floating on the water surface adsorbing the substance to be adsorbed.

The water quality improving tool 1 is suspended on the water surface by the floating body 13, but it can also be floated in water by adjusting the number of floating bodies 13 or by attaching a weight (not shown) to the water quality improving tool 1. Therefore, in addition to impurities near the water surface, impurities in each layer of water are also adsorbed, and the water to be treated is purified.

The purified water to be treated can be used not only as drinking water, but also as drinking water for livestock, water for aquaculture, water for hydroponics, and the like.

As described above, it is effective for improving the water quality of the water to be treated, but it also has a certain effect when removing radioactive substances from contaminated water contaminated with radioactive substances, and thus will be described below.

Contaminated water contaminated with high concentrations of radioactive substances cannot be drained as it is. For the treatment of water contaminated with high-concentration radioactive substances, contaminated water is isolated and stored in a remote place such as a mountainous area in order to reduce the environmental destruction caused by radioactivity and the impact on the human body as much as possible. Furthermore, it is necessary to remove the radioactive substance from the contaminated water to which the radioactive substance such as radioactive cesium is attached. Examples of the types of radioactive substances include iodine-131, cobalt-60, cesium-134, cesium-137, radium-226, plutonium-239, uranium-238, and strontium-90.

Although radioactive substances must be removed from such contaminated water, the water quality improving tool 1 of the first and second embodiments of the present invention can purify the contaminated water by adsorbing the radioactive substances.

When the water quality improving tool 1 is floated in the water to be treated, substances such as radioactivity can be collected and removed by the "heavy metal ion adsorption capacity" possessed by photosynthetic bacteria. That is, when cesium is adsorbed on the carrier to which sulfur bacteria are attached, cesium is removed and disappears from the water to be treated, and the water to be treated is purified.

Water from which cesium has been removed can be flushed into the sea by such a purification effect. Further, the carrier 10 to which sulfur adsorbed by cesium is attached can be buried in the ground and disposed of, and the carrier 10 to which sulfur adsorbed by cesium is attached can be incinerated and disposed of.

Next, the water quality improving tool 1 of another embodiment will be described. The main constituent article of the water quality improving tool 1 of the other embodiment is composed of a carrier 10, a bearing support 50, a shaft 51, a substrate 10, a fishing line and the like (see FIG. 4). Hereinafter, each of these constituent articles will be described.

In another embodiment, the carrier 10 that supports sulfur 5 is composed of a mesh-shaped tubular body that supports sulfur 5. This cylindrical body is a bottomless cylinder, that is, a cylinder with both ends open. Examples of the material include metals, non-ferrous metals, resins and the like. Examples of the shape include a cylinder, a triangular cylinder, a square cylinder, and other mesh-like ones having a certain mesh of polygonal cylinders. Further, the mesh is not particularly limited, and may be of any size and mesh shape.

As described above, since the carrier 10 is a tubular body, it has an internal space in the tubular body, and the bearing support 50 is accommodated in this internal space. The bearing support 50 is made of a foamable material that floats in water, and has a shaft hole through which the shaft 51 is inserted. As the foamable material, for example, foamed plastic or the like is applicable. Further, it may be fiber reinforced plastic (FRP) or the like. In addition, the buoyancy may be increased by providing an air chamber inside the floating body 13. As described above, since the bearing support 50 is made of a foamable material, the water quality improving tool 1 of the other embodiment floats in the water to be treated.

The shaft 51 supports the water quality improving tool 1 itself of another embodiment, and is inserted through the bearing support 50 to rotatably support the water quality improving tool 1. The material of the shaft 51 may be any material, and examples thereof include synthetic resin pipes and vinyl chloride pipes.
