Description

DETAILED DESCRIPTION OF THE INVENTION <Field of industrial application> The present invention relates to a water quality modifying agent, a method for producing the same, a method for improving water quality, and an apparatus therefor.

<Conventional technology> In recent years, water cleaning agents, plant freshness preservation agents, preservatives, wastewater treatment agents,
Divalent and trivalent iron salt compounds are attracting attention as soil conditioners, ionization inhibitors, rust preventives, feed fortifiers, and the like. This is proposed by Mr. Yamashita of Nagoya University (Japanese Patent Application Laid-Open No. 186581/1981)
This is due to the fact that when compounding the alkali metal salt of divalent and trivalent iron, a substance with remarkable biological activity and ionization suppressing effect was obtained. By him, F etc Is”xHt.

F e 3c l 7”X HtO F e 3C1s”X l-1t.

A method for producing divalent and trivalent iron salts such as ferric salts and formulations thereof have been proposed.

The products (purified products) include those obtained by concentrating (crystals) in powder form or those obtained as diluted water. Crystalline powders are listed as a magnesium complex, a plant-related a complex, and a soybean protein complex.

<Problem to be solved by the invention> However, in reality, no products with commercial properties have been proposed for commercialization for the purpose of improving water quality. That is, the above-mentioned products or formulations could not be applied to actual water quality improvement. For example, when using divalent and trivalent iron salts in flowing water, it may be necessary to use them in water that is being circulated for the purpose of improving the water quality of an aquarium containing live fish or for other purification purposes. be. At this time, there was concern that the efficacy of the divalent and trivalent iron salts would not be sufficiently effective.

Specifically, when obtained as the above-mentioned crystalline powder or mixture, it is possible to dissolve it in still water and use it, but it has not been possible to interpose it in a flowing water path.

This is because it is difficult to maintain an appropriate amount of dissolution, and it is very tedious to gradually add and maintain a target concentration to flowing water. In still water, it is easy to maintain a constant concentration by diffusion, but in flowing water,
- You end up eluting everything at once. As a result, there may be a mixture of substances that dissolve too much and have a concentration higher than the target concentration, and substances that flow out and do not reach the predetermined concentration even though sufficient diffusion has taken place to reach a certain concentration. Therefore, it has been difficult to elute a certain amount of divalent and trivalent iron salts to a constant concentration in flowing water.

The fact that the predetermined M cannot always be obtained means that quantitative reproducibility of effects cannot be expected, which is fatal as a product.

Furthermore, it has been difficult to manage the above-mentioned products or formulations as they are, regardless of whether they are used in still water or running water. For example, when it is commercialized as a crystalline powder, management such as maintaining a dry state is required, and when it is commercialized as dilution water, the cost of transportation increases due to the increase in weight t1.

As mentioned above, there are still no products that have been given an appropriate shape, and the present invention aims to solve the above problems.

<Means for Solving the Problems> The present invention provides: - A water quality improver characterized by containing divalent and trivalent iron salts inside a body made of ceramics; ■ Diluted water of divalent and trivalent iron salts; A method for producing a water quality improving agent, characterized in that the ceramics are immersed in the water, heated to an appropriate temperature, heated for an appropriate time, then taken out from the dilution water, and dried to obtain a water quality improving agent ■ Divalent and trivalent iron salt. Water quality improvement method characterized by intervening ceramics containing divalent and trivalent iron salts in untreated water ■Ceramics containing divalent and trivalent iron salts are placed inside the main body17, and untreated water is further introduced from the outside into the above-mentioned receiving part. The present invention aims to provide a water quality improvement device characterized by comprising a water conduit and an outflow pipe for draining treated water to the outside.

In the present invention having the above-mentioned means, ■ the divalent and trivalent iron salt is contained in the ceramic, so that it is given an appropriate shape and weight q[J5, and is formed in a predetermined manner in the water flow path. Ceramics can absorb flowing water and elute an appropriate amount of the divalent and trivalent iron salt into the absorbed water.

■Since diluted water can easily penetrate into the ceramic nox, which is naturally highly water-permeable, divalent and trivalent iron salts can be easily impregnated into the ceramic. It is recrystallized and retained.

■The divalent and trivalent iron salts can be gradually discharged to the outside in appropriate amounts, and the concentration of the divalent and trivalent iron salts in the water can be kept almost constant for a predetermined period of time.

■It is possible to introduce flowing water through a water pipe and pass the appropriate amount of water through the ceramics containing divalent and trivalent iron salts to dissolve the divalent and trivalent iron salts. , it is possible to flow out to the target area.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail by way of example with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this example are not intended to limit the scope of this invention to only those, unless otherwise specified. , is merely an illustrative example.

FIG. 1 shows an embodiment of the present invention. As shown here,
A product is produced by impregnating a ceramic molded article (1) with a suitable shape with divalent and trivalent iron salt. Here, it is carried out as a cylindrical hollow ceramic molded product (1), but it can also be used as a cylinder, a prism, a spherical body, a tablet-shaped body, a cube, a rectangular parallelepiped, a tetrahedron, other faces, or other hollow members. It can also be implemented by molding. Materials that maintain appropriate strength, weight, and permeability (e.g., porous materials)
If so, it may be used instead of ceramics. In particular, the reason why ceramics are used is that we focused on the fact that they do not inhibit the bioactive factors of divalent and trivalent iron salts. Ceramics are originally used for artificial bones, and are compatible with living organisms without interfering with their functions. Therefore, there is no problem in maintaining the divalent and trivalent iron salts that are contained in living organisms.

Furthermore, it is effective if the ceramic itself is appropriately selected and carried out as described below depending on the purpose. For example, when sintering ceramic powder, divalent and trivalent iron salts may be added to adjust the composition to some extent in advance, and then the divalent and trivalent iron salts can be added to reach the desired content through the steps described below. , it is also possible to implement using such ceramics. Also far infrared emitting ceramics, pure oxygen generating solid (solid oxygen)
It is more effective if various ceramics are used depending on the purpose, such as ceramics and mineral-containing ceramics.

The process of completing the product as shown in Figure 1 will be described below. First, ceramics are molded into the required shape. Ceramics are molded by a conventional method. The shape may be determined by selecting the volume and surface area depending on the purpose. After this, the ceramics are placed in water diluted with divalent and trivalent iron salt and heated. Of course, it is also possible to heat divalent iron salt divalent water in advance and add ceramics during the heating process.

Heating is suitably carried out up to 100°C. Of course 100
It does not level off even below ℃ (it does not boil even if heated to 100℃ due to the upper molar limit). After heating for a suitable time, the ceramic is taken out and dried naturally or by force. A product is thus obtained.

Water quality improver and 1. Once the product has been manufactured through the above steps, it can be used as is or by being added to the water path. Of course, it can also be used by putting it into still water.

In particular, the use of divalent and trivalent iron salts in flowing water may be used to improve the water quality of an aquarium containing live fish, or in water that is being circulated for biochemical purposes. Appropriate water quality improvement devices at this time are listed below. An embodiment of the apparatus is shown in FIGS. 2, 3, 4, 5, and 6.
