Description

[Technical Field]

[0001] The present invention relates to a sediment and water purification material for a water bottom where bottom mud has accumulated, and a method for purifying sediment and water. [Background technology]

[0002] Methods of using iron fulvic acid to improve the water quality of deteriorated bottom sediment environments (aquatic environments) in closed or semi-closed water areas such as harbors, lakes, marshes, and tidal flats are known (e.g., Patent Documents 1 and 2). In this method, fulvic acid reacts with oxygen dissolved in water through light to produce hydrogen peroxide. The hydrogen peroxide produced is then converted into iron (Fe 2+ ) (Fenton reaction) and trivalent iron (Fe 3+ ) and hydroxyl radicals are generated. The strong oxidizing action of the generated hydroxyl radicals decomposes the organic matter in the sludge contained in the bottom sediment environment (aquatic environment), thereby purifying the bottom sediment environment (aquatic environment). However, in the method using iron fulvic acid, the Fenton reaction produces ferrous iron (Fe 2+ ) is trivalent iron (Fe 3+ ), there was a problem that even if hydrogen peroxide was generated by light irradiation, hydroxyl radicals were not generated.

[0003] On the other hand, water containing mineral components is believed to have the potential to improve soil, promote plant growth, decompose harmful chemicals, deodorize, purify the air, and other beneficial effects, and various mineral-containing waters and production facilities for mineral-containing waters have been developed. The inventor has developed a mineral-containing water manufacturing device (A) that includes a means for immersing a conductive wire coated with an insulator and a mineral-donating material (A) in water, passing a direct current through the conductive wire, generating a water flow in the same direction as the direct current in the water around the conductive wire, and applying ultrasonic vibrations to the water to form a raw mineral aqueous solution (A), and a far-infrared generating means for irradiating the formed raw mineral aqueous solution (A) with far-infrared rays to form mineral-containing water (A) (see Patent Document 3). The inventors have also developed a mineral functional water production facility equipped with a mineral-containing water production device (B) that includes a mineral-containing water production device (A), multiple water-passing containers filled with different types of mineral-imparting materials (B), a water-transport path connecting the multiple water-passing containers in series, bypass water channels connected to the water-transport path in parallel with the multiple water-passing containers, and water flow switching valves provided at each branch point between the water-transport path and the bypass water channel (see Patent Document 4).The inventors have reported that the mineral functional water production facility can be used to produce mineral functional water (far-infrared-generating water) that has the function of emitting far-infrared rays with a characteristic wavelength.

[0004] On the other hand, even in the device reported in Patent Document 4, the types and blending ratios of the raw materials for the mineral components (mineral imparting materials) used in the mineral-containing water production devices (A) and (B) are particularly involved in a complex manner, and it was not necessarily clear what effects mineral functional water would have if a specific mineral imparting material was used. However, the inventors used the mineral functional water production equipment disclosed in Patent Document 4 and conducted extensive research, focusing on the types and blending ratios of the mineral imparting materials, and discovered that mineral functional water produced under certain conditions has excellent pest control effects against unicellular organisms (Patent Documents 5 and 6), a physical revitalizing effect (Patent Document 7), a promotion effect on the combustion of hydrocarbons (Patent Document 8), and an antioxidant effect (Patent Document 9).

[0006] As mentioned above, various mineral-containing waters have been reported, but the effects of many of them have not been scientifically proven, and the true functions of mineral-containing water remain largely unclear. As a result, many conventional mineral-containing waters claim to have beneficial effects but do not actually have them, or even if they do have beneficial effects, they are insufficient for practical use or have poor reproducibility. Even the mineral functional waters produced by the apparatuses reported by the inventor in Patent Documents 3 and 4 have not been able to reliably produce mineral functional water that exhibits the desired beneficial effects. In particular, the types and blending ratios of the mineral component raw materials (mineral-imparting materials) used in the mineral-containing water production apparatuses (A) and (B) reported in Patent Document 4 are intricately related, and it has not always been clear what mineral-imparting materials would produce what beneficial effects in mineral functional water. Furthermore, no studies have been conducted on bottom sediment purification or water purification technologies using mineral functional water or the mineral components derived from it.

[0012] The present invention will be described in detail below using examples, etc., but the present invention is not limited to the examples below and can be practiced with any modifications within the scope of the gist of the present invention. In this specification, the symbol "to" is used as an expression including the numerical values ​​or physical quantities before and after it. In addition, in this specification, the expression "A and / or B" includes "A only," "B only," and "both A and B."

[0013] In this specification, the term "mineral functional water" refers to water that contains mineral components and exhibits at least one effective effect.

[0014] In this specification, "mineral-containing water" refers to raw water used in the initial stage of producing mineral functional water, and mineral-containing water also contains mineral components. Details will be described later in the description of the method for producing mineral functional water of the present invention. Note that mineral-containing water itself may or may not have effective effects.

[0015] In this specification, "mineral components" does not mean "inorganic components (including trace elements) excluding the four elements (carbon, hydrogen, nitrogen, and oxygen)" which is the narrow definition of minerals, but may contain the four elements (carbon, hydrogen, nitrogen, and oxygen) excluded in the narrow definition, provided that they coexist with inorganic components. Therefore, for example, "plant-derived mineral components" is a concept that includes plant-derived organic components as well as plant-derived inorganic components such as calcium. In addition, examples of inorganic components (constituting mineral components) include, but are not limited to, sodium, potassium, calcium, magnesium, and phosphorus, and trace elements such as iron, zinc, copper, manganese, iodine, selenium, chromium, and molybdenum.

[0016] <1. Bottom sediment water purification material> The present invention relates to a sediment water purification material (hereinafter referred to as "the purification material of the present invention") that contains (a) mineral functional water containing mineral components, (b) humic substance containing fulvic acid, and (c) an iron supply material. The purifying material of the present invention has a "sediment and water purification effect," that is, an effect of decomposing and purifying organic matter contained in the sediment and / or water.

[0017] The purification material of the present invention is characterized in that it contains (a) mineral functional water containing mineral components, together with (b) humic substances containing fulvic acid that contribute to the Fenton reaction, and (c) iron supply material. Here, the "Fenton reaction" refers to the reaction of ferrous iron (Fe 2+ ) reacts with hydrogen peroxide (H2O2) to form trivalent iron (Fe 3+ ) and generates hydroxyl radicals.

[0018] The purifying action of the purifying material of the present invention will now be described. Fulvic acid contained in the humic substance (b) contained in the purification material of the present invention is a component of humic substances that is soluble in alkali and acid, and is distinguished from humic acid, which is a substance that is soluble in alkali and water but precipitates in acidic conditions, and humin, which is an insoluble substance. Fulvic acid is a substance with a condensed aromatic structure and a phenolic hydroxyl group and a carboxyl group, so it has the ability to complex (chelate) with mineral components. It also has the ability to absorb ultraviolet rays and generate hydrogen peroxide (H2O2).

[0019] When the purification material of the present invention is irradiated with ultraviolet light (e.g., sunlight), the fulvic acid derived from the purification material of the present invention first reacts with dissolved oxygen in water through a photoreaction to produce hydrogen peroxide. The produced hydrogen peroxide reacts with the divalent iron ions eluted from the iron supply material (c) (Fenton reaction) to produce divalent iron (Fe 2+ ) to trivalent iron (Fe 3+ ) and generates hydroxyl radicals. The generated hydroxyl radicals have a strong oxidizing effect and purify the water and bottom sediment by oxidizing and decomposing organic matter on the bottom and in the water.

[0020] In the Fenton reaction, trivalent iron (Fe 3+ ) and divalent iron (Fe 2+ If there is a shortage of fulvic acid, the reaction will not proceed even if hydrogen peroxide is produced by the photoreaction of fulvic acid. In particular, when the sediment or water quality of the water area to be treated contains a large amount of organic matter (i.e., is polluted), iron (Fe) is released during light irradiation. 2+ ) may be insufficient, making it difficult for the decomposition of organic matter through the Fenton reaction to proceed.

[0021] The electromagnetic wave-emitting mineral component contained in the purification material of the present invention is a mineral component derived from the mineral functional water (a). The electromagnetic wave-emitting mineral component has reducing power and is capable of reducing trivalent iron (Fe 3+) to divalent iron (Fe 2+ ) has the effect of reducing it. In the purifying material of the present invention, the reducing power derived from the mineral components is believed to be expressed regardless of whether or not light irradiation is performed. In other words, when irradiated with light, the Fenton reaction becomes dominant over the reducing power derived from mineral components, and the divalent iron (Fe 2+ ) to trivalent iron (Fe 3+ ), but when there is no light (darkness), hydrogen peroxide is not produced by fulvic acid, so the Fenton reaction does not occur, and the reduction action of the mineral components derived from mineral functional water (a) causes trivalent iron (Fe 3+ ) is divalent iron (Fe 2+ ) is reduced to Therefore, the Fenton reaction proceeds during light irradiation (daytime), and the ferrous iron (Fe 2+ Even if there is a shortage of iron (Fe), the dark condition (nighttime) will allow the 2+ ) increases, and when light is irradiated again (during the daytime), the amount of ferrous iron (Fe 2+ The Fenton reaction proceeds without a shortage of

[0022] The purifying material of the present invention can repeatedly carry out the Fenton reaction and continuously exhibits an excellent decomposition effect of organic matter.

[0023] The constituent components of the purification material of the present invention will be described below.

[0024] (Mineral functional water (a) and mineral components) The mineral components derived from the mineral functional water (a) contained in the purification material of the present invention are mineral components derived from mineral functional water containing mineral-containing water (A) formed in the following step (1) and mineral-containing water (B) formed in the following step (2) in a weight ratio of 1:5 to 1:20. The term "mineral components derived from mineral functional water" refers to the mineral components remaining after removing the solvent from the mineral functional water. However, as mentioned above, plant-derived mineral components include not only inorganic components but also organic components derived from plants.

[0025] Process (1): a step of immersing a conductive wire covered with an insulator and a mineral-imparting material (A) containing herbaceous plant raw materials consisting of herbaceous plants of the Asteraceae family and herbaceous plants of the Rosaceae family, and woody plant raw materials consisting of one or more woody plants selected from maple, birch, pine, and cedar, in water, passing a direct current through the conductive wire, generating a water current in the same direction as the direct current in the water around the conductive wire, and imparting ultrasonic vibrations to the water to form a raw mineral aqueous solution (A), and then irradiating the raw mineral aqueous solution (A) with far infrared rays (wavelength 6 to 14 μm) to form mineral-containing water (A), The amount of the mineral-imparting material (A) added to the water is 10 to 15% by weight, and the current value and voltage value of the direct current passed through the conductive wire are in the ranges of 0.05 to 0.1 A and 8000 to 8600 V, respectively; and Mineral-donating material (A) As the herbaceous plant raw materials, wild thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) are mixed in proportions of 8 to 12% by weight, 55 to 65% by weight, and 27 to 33% by weight, respectively, dried, and then pulverized. The method uses dried and pulverized products of plants of the Rosaceae family, which are obtained by mixing, respectively, 17 to 23% by weight of Rosa multiflora (leaves and flowers), 8 to 12% by weight of Geum japonicum (leaves and stems), and 65 to 75% by weight of Rubus idaeus (leaves, stems, and flowers), drying the mixture, and pulverizing the mixture; a herbaceous plant material (A1) obtained by mixing the dried and pulverized product of the Asteraceae plant and the dried and pulverized product of the Rosaceae plant in a weight ratio of 1:0.8 to 1:1.2; As the woody plant raw material, maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) were mixed in proportions of 22 to 28% by weight, 22 to 28% by weight, and 45 to 55% by weight, respectively, and dried and then pulverized to obtain a woody plant raw material (A2). A process for producing a mineral-imparting material (A') by mixing herbaceous plant material (A1) and woody plant material (A2) in a weight ratio of 1:2.7 to 1:3.3.

[0026] Process (2): Six water-passing vessels from the first water-passing vessel to the sixth water-passing vessel are filled with different types of inorganic mineral-providing materials (B) and connected in series, The mineral-providing material (B1) in the first water-passing container is a mixture containing 70% by weight of limestone, 15% by weight of fossil coral, and 15% by weight of seashells, respectively; The mineral-imparting material (B2) in the second water-passing container is a mixture containing limestone, fossil coral, seashells, and activated carbon in amounts of 40 wt%, 15 wt%, 40 wt%, and 5 wt%, respectively; The mineral-donating material (B3) in the third water-passing container is a mixture containing 80% by weight of limestone, 15% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-donating material (B4) in the fourth water-passing container is a mixture containing 90% by weight of limestone, 5% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-donating material (B5) in the fifth water-passing container is a mixture containing 80% by weight of limestone, 10% by weight of fossil coral, and 10% by weight of seashells, respectively; The mineral-donating material (B6) in the sixth water-passing container is a mixture containing limestone, fossil coral, and seashells in 60 wt%, 30 wt%, and 10 wt%, respectively; A step of forming mineral-containing water (B) by passing water through the six water-passing containers to produce mineral-containing water (B).

[0027] The method for producing the mineral functional water will be described in detail later.

[0028] The mineral functional water (a) used in the purifying material of the present invention includes the mineral functional water developed by the present inventors (sometimes referred to as "the mineral functional water of the present invention"). A common feature of the mineral functional water of the present invention is that it contains plant-derived mineral components (particularly plant-derived organic components).

[0029] As the mineral functional water (a), mineral functional water CAC-717 manufactured by Riken Technosystem Co., Ltd. is preferably used, as will be explained in detail in the Examples.

[0030] (humic substances (b)) Humic substances (b) are humic substances that contain fulvic acid. Fulvic acid is a component of humic substances that is both alkali-soluble and acid-soluble, and is distinguished from humic acid, which is soluble in alkaline water and precipitates in acidic conditions, and humin, which is an insoluble substance. Fulvic acid is a substance with a condensed aromatic structure and a phenolic hydroxyl group and a carboxyl group, so it has the ability to complex (chelate) with mineral components. It also has the ability to absorb ultraviolet rays and generate hydrogen peroxide (H2O2).

[0031] The origin and composition of the humic substance (b) are not particularly limited as long as the effects of the present invention are achieved, but it is preferable that the humic substance be derived from peat, as it easily generates hydrogen peroxide when irradiated with light and is not easily decomposed by oxidation.

[0032] (Iron Feedstock (c)) The iron supply material (c) is a material that supplies elemental iron, and metallic iron (Fe), compounds containing divalent iron, and compounds containing trivalent iron can be used. These can be used alone or in combination.

[0033] Examples of metallic iron as the iron supply raw material include iron powder, iron ore, iron sand, iron material, etc. The iron supply raw material may be in the form of a lump, but is preferably in the form of a powder.

[0034] Examples of divalent iron compounds as iron supply raw materials include iron compounds such as iron(II) chloride, iron(II) nitrate, iron(II) sulfate, iron(II) hydroxide, and iron(II) oxide.

[0035] Examples of trivalent iron compounds as iron supply raw materials include water-soluble iron compounds such as iron(III) chloride and iron(III) sulfate; insoluble iron compounds such as iron(III) oxide, iron(III) nitrate, and iron(III) hydroxide; Akadama soil, Kanuma soil, loam (soil containing a lot of allophanic iron), and laterite (soil containing a lot of iron(III) oxide). Although trivalent iron does not contribute to the Fenton reaction, as described above, in the purification material of the present invention, trivalent iron can be reduced to divalent iron by the mineral components derived from the mineral functional water (a) in the dark, so that divalent iron can be substantially supplied.

[0036] As the iron supply material, it is preferable to use metallic iron powder or an inexpensive iron compound (iron compound such as iron chloride or iron sulfate: either divalent or trivalent iron compounds). In particular, from the viewpoint of raw material costs and stable supply, it is preferable to use metallic iron as the iron supply raw material, and powdered metallic iron is preferred.

[0037] The purifying material of the present invention can be produced by mixing mineral functional water (a), humic substances (b), and an iron supply material (c). As mentioned above, humic substances (especially fulvic acid) contain many phenolic and carboxyl groups, and these combine with the mineral components derived from the mineral functional water (a) and the divalent iron and trivalent iron derived from the iron supply material (c), thereby making the purification material of the present invention a solid.

[0038] There is no limitation on the order of mixing the mineral functional water (a), humic substances (b), and iron supply material (c). A suitable example, as shown in the examples below, is a production method having a step of mixing the mineral functional water (a) and humic substances (b) to obtain a clay-like mixture, and a step of mixing the clay-like mixture with the iron supply material (c).

[0039] The blending ratio of the mineral functional water (a), humic substances (b), and iron supply material (c) in the purification material of the present invention is not limited as long as it has the effect of the present invention (the desired purification action), and is appropriately set taking into consideration the types of mineral functional water (a), humic substances (b), and iron supply material (c), the organic matter concentration in the water area to which the material is to be applied, and the like.

[0040] The purification material of the present invention may be composed only of mineral functional water (a) (mineral components derived from mineral functional water (a)), humic substances (b) and iron supply material (c), but it may also be mixed with or supported by other materials (ceramic supports). The purifying material of the present invention may be directly sprayed onto the water area to be treated, or may be packed into a water-permeable bag and allowed to settle and be retained at the bottom of the target water.

[0041] The method for applying the purification material of the present invention is appropriately selected depending on the purpose. Typical examples include a method in which the purification material of the present invention is scattered on the bottom of the water to be purified, a method in which the material is packed in a bag and then submerged, or a method in which the material is scattered in the water area to be purified.

[0042] The water body to which the purification material of the present invention is applied is typically seawater, but may also be freshwater (rivers, lakes, marshes, etc.).

[0043] <2. How to make mineral functional water> The mineral functional water (a) suitable for use in producing the purification material of the present invention can be produced using the apparatus disclosed in Patent Document 4 (JP 2011-56366 A) and a method similar to that disclosed in the same document.

The following description corresponds to the method for producing mineral functional water CAC-717 manufactured by Riken Technosystem Co., Ltd., which is one of the preferred mineral functional waters (a).

[0045] As shown in Figure 1, the mineral functional water production equipment 1 includes a mineral-containing water (A) production device 2, a mineral-containing water (B) production device 3, and a mixing tank 46, which is a mixing means for mixing mineral-containing water (A) 44 produced in the mineral-containing water (A) production device 2 with mineral-containing water (B) 45 produced in the mineral-containing water (B) production device 3 to form mineral functional water 47.

[0046] The mineral-containing water (A) manufacturing device 2 includes a raw mineral aqueous solution manufacturing means 10 that forms a raw mineral aqueous solution (A) 41 using water 11 supplied from the tap and a mineral-providing material (A) 12 (see Figure 4) described below as raw materials, and a far-infrared generation means 43 that irradiates the raw mineral aqueous solution (A) 41 obtained by the raw mineral aqueous solution manufacturing means 10 with far-infrared rays to change it into mineral-containing water (A) 44.

[0047] The mineral-containing water (B) manufacturing device 3 has the function of forming mineral-containing water (B) 45 containing mineral components eluted from the mineral-providing material by passing water W supplied from the outside through water-passing containers 51 to 56.

[0048] The mineral-containing water (A) production apparatus 2 and the mineral-containing water (B) production apparatus 3 will be described in detail below.

[0049] (Mineral water (A) production equipment) Next, with reference to Figures 2 to 6, the mineral-containing water (A) production device 2 constituting the mineral functional water production facility 1 shown in Figure 1 will be described. As shown in Figure 1, the mineral-containing water (A) production device 2 includes a raw mineral aqueous solution production means 10 (see Figure 2) that forms a raw mineral aqueous solution (A) 41 using water 11 supplied from a tap and a mineral imparting material (A) 12 (see Figure 4) described below as raw materials, and a far-infrared generation means 43 (see Figure 6) that irradiates the mineral-containing water (A) solution 41 obtained in the raw mineral aqueous solution production means 10 with far-infrared rays to change it into mineral-containing water (A) 44.

[0050] 2 and 3, raw mineral aqueous solution manufacturing means 10 includes a reaction vessel 13 capable of containing water 11 and mineral-imparting material (A) 12, a conductive wire 15 covered with an insulator 14 and immersed in the water 11 in reaction vessel 13, ultrasonic generator 16 for applying ultrasonic vibrations to the water 11 in reaction vessel 13, a DC power supply 17 for passing direct current DC through conductive wire 15, and circulation paths 18a, 18b and a circulation pump P as means for generating a water current R in the water 11 around conductive wire 15 in the same direction as the DC current DC. The DC power supply 17, ultrasonic generator 16, and circulation pump P are all powered by a general commercial power source.

[0051] The reaction vessel 13 is an inverted conical cylinder with an open top, and has a drain outlet 19 at the bottom, which corresponds to the apex. This drain outlet 19 is connected to a circulation path 18a that communicates with the suction port P1 of the circulation pump P, and directly below the drain outlet 19 are provided an opening adjustment valve 20 for adjusting the amount of water discharged into the circulation path 18a, and a drain valve 21 for discharging water and the like from the reaction vessel 13.

[0052] The base end of circulation path 18b is connected to discharge port P2 of circulation pump P, and the tip end of circulation path 18b is connected to storage tank 22. The base end of circulation path 18c for sending water 11 in storage tank 22 into reaction vessel 13 is connected to the bottom of the outer periphery of storage tank 22, and the tip end of circulation path 18c is piped at a position facing the opening of reaction vessel 13. Circulation path 18c is provided with an aperture adjustment valve 23 for adjusting the amount of water sent from storage tank 22 to reaction vessel 13.

[0053] A drain pipe 24 having a drain valve 25 and a water thermometer 26 is connected to the bottom of the storage tank 22 in a hanging manner. When the drain valve 25 is opened as needed, the water in the storage tank 22 can be discharged from the lower end of the drain pipe 24, and the temperature of the water 11 passing through the drain pipe 24 can be measured by the water thermometer 26.

[0054] As shown in FIG. 5, multiple conductive cables 29 (29a-29g), each consisting of a conductive wire 15 and an insulating material 14 covering the conductive wire 15, are wired in a circular shape at multiple positions at different depths within the reaction vessel 13, and each of these circular conductive cables 29a-29g is arranged approximately coaxially with the reaction vessel 13. The inner diameter of each of the conductive cables 29a-29g is gradually reduced to match the inner diameter of the inverted conical reaction vessel 13, and each has an inner diameter corresponding to the respective placement location. Each of the conductive cables 29a-29g is detachably connected to an insulating terminal 30 provided on the wall 13a of the reaction vessel 13, so that the circular portion can be removed from or attached to the terminal 30 as needed.

[0055] A cylindrical storage container 31 with a bottom made of an insulating mesh body is placed in a portion corresponding to the axis of the reaction container 13, and this storage container 31 is filled with the mineral-imparting material (A) 12. This storage container 31 is detachably fastened to the upper edge of the wall 13a of the reaction container 13 by a hook 31f provided on the top of the storage container 31.

[0056] 2, conductive cables 29s and 29t are spirally wound around the outer peripheries of the circulation paths 18a and 18b, respectively, and direct current DC is supplied to these conductive cables 29s and 29t from a DC power supply device 17. The direction of the direct current DC flowing through the conductive cables 29s and 29t is set to substantially coincide with the direction of the water flowing in the circulation paths 18a and 18b.

[0057] In the raw mineral aqueous solution producing means 10, a predetermined amount of water 11 is placed in the reaction vessel 13 and the storage tank 22, and the storage vessel 31 filled with the mineral-imparting material (A) 12 is set in the center of the reaction vessel 13. Then, the circulation pump P is operated, and the aperture adjustment valve 20 at the bottom of the reaction vessel 13 and the aperture adjustment valve 23 of the circulation path 18c are adjusted to circulate the water 11 from the reaction vessel 13 via the drain outlet 19, the circulation path 18a, the circulation pump P, the circulation path 18b, the storage tank 22, and the circulation path 18c, and back to the top of the reaction vessel 13. Then, the DC power supply 17 and the ultrasonic generating means 16 are operated, and the elution reaction of mineral components from the mineral-imparting material (A) 12 in the storage vessel 31 into the water 11 begins.

[0058] The working conditions for producing the raw mineral aqueous solution (A) using the raw mineral aqueous solution producing means 10 are not particularly limited, but in this embodiment, the raw mineral aqueous solution (A) was produced under the following working conditions. (1) A direct current DC of a voltage of 8000 to 8600 V and a current of 0.05 to 0.1 A was passed through the conductive cables 29, 29s, and 29t. The insulator 14 constituting the conductive cable 29 and the like was made of polytetrafluoroethylene resin. (2) The mineral-imparting material (A) 12 filled in the reaction vessel 13 is filled in an amount of 10 to 15% by mass relative to the water 11. A specific description of the mineral-imparting material (A) 12 will be given later. (3) The water 11 may contain an electrolyte so that the direct current DC can act on it. For example, about 10 g of sodium carbonate, an electrolyte, is dissolved in 100 liters of water, but groundwater can also be used as is. (4) The ultrasonic generating means 16 generates ultrasonic waves with a frequency of 30 to 100 kHz, and is positioned so that its ultrasonic vibration part (not shown) directly contacts and vibrates the water 11 in the reaction vessel 13.

[0059] When the raw mineral aqueous solution manufacturing means 10 is operated under these conditions, a water flow R is generated in the reaction vessel 13, which rotates in a left-handed screw direction and is sucked into the drain outlet 19, and the water 11 discharged from the drain outlet 19 returns to the reaction vessel 13 via the aforementioned circulation paths 18a, 18b, etc., and this state continues.

[0060] Therefore, due to the stirring action of the water flow R, the action of the direct current flowing through the conductive cable 29, and the ultrasonic vibrations applied to the water 11 by the ultrasonic generating means 16, the mineral components are quickly dissolved from the mineral-donating material (A) 12 into the water 11, and a raw mineral aqueous solution (A) in which the required mineral components are appropriately dissolved can be efficiently produced.

[0061] In the raw mineral aqueous solution producing means 10, a plurality of circular conductive cables 29a-29g are wired approximately coaxially within the reaction vessel 13, and a water flow R that rotates in a left-handed screw direction is generated within the reaction vessel 13. Therefore, a relatively dense electric energy field can be formed within the reaction vessel 13, which has a fixed volume, and the raw mineral aqueous solution (A) can be efficiently produced within the reaction vessel 13, which has a relatively small volume.

[0062] Furthermore, because reaction vessel 13 is in the shape of an inverted cone, it is possible to generate water flow R that flows along the plurality of circular conductive cables 29a-29g relatively easily and stably, thereby promoting the elution of mineral components. Furthermore, the flow rate of water flowing inside reaction vessel 13 in the shape of an inverted cone increases as it moves toward drain outlet 19 at the bottom of reaction vessel 13, which increases the frequency of contact with mineral-imparting material (A) 12 and increases the amount of minerals that are ionized by capturing free electrons e present in water 11.

[0063] Furthermore, since the storage tank 22 that stores and discharges the water 11 is provided between the circulation paths 18b and 18c, it is possible to proceed with the mineral elution reaction while circulating an amount of water 11 that exceeds the capacity of the reaction vessel 13. This allows for efficient mass production of the raw mineral aqueous solution (A).

[0064] By continuously operating the circulation pump P and continuing these reactions, a raw mineral aqueous solution (A) is eventually produced from which the mineral components have been eluted. The appearance of free electrons e in water 11 can be controlled by the size of the drain outlet 19 at the bottom of the reaction vessel 13, the amount of circulating water, and the shape of the reaction vessel 13 (particularly the angle γ between the axis C and the wall 13a shown in Figure 2), and the water solubility of the mineral components is determined by the effect of the free electrons e on the mineral-donating material (A) 12.

[0065] Once the raw mineral aqueous solution (A) is formed, this raw mineral aqueous solution (A) 41 is transferred into a treatment vessel 40 shown in Figure 6. In this case, any residue of the mineral-imparting material (A) 12 that has leaked from the storage container 31 in the reaction vessel 13 can be discharged through a drain valve 21 at the bottom of the reaction vessel 13. The raw mineral aqueous solution (A) 41 contained in the treatment vessel 40 is irradiated with far-infrared rays by a far-infrared generating means 43 arranged inside the treatment vessel 40 while being slowly stirred with a stirring blade 42.

[0066] The far-infrared generating means 43 may be any means that generates far-infrared rays with a wavelength of about 6 to 14 μm, and may be a heating type, regardless of the material or generating means. However, it is desirable that the radiation ratio of the far-infrared rays at 25°C is 85% or more of the blackbody radiation in the wavelength range of 6 to 14 μm.

[0067] In the raw mineral aqueous solution manufacturing means 10 shown in Figure 2, the mineral components contained in the mineral-donating material (A) 12 are quickly dissolved into the water 11 by the stirring action of the water flow R, the action of the direct current DC flowing through the conductive wire 15, and ultrasonic vibration, so that the required mineral components are appropriately dissolved, and the mineral aqueous solution 41 can be efficiently manufactured.

[0068] Then, in the far-infrared generating means 43 shown in Figure 6, by irradiating the mineral aqueous solution 41 with far-infrared rays, the dissolved mineral components and water molecules fuse together to form mineral-containing water (A) 44 with increased electronegativity.

[0069] In the mineral-containing water (A) manufacturing apparatus 2, the mineral-containing water (A) 44 formed by the above-mentioned process is sent to a mixing tank 46 via a water supply path 57y, as shown in Figure 1, and in the mixing tank 46 is mixed with mineral-containing water (B) 45 sent from the mineral-containing water (B) manufacturing apparatus 3.

[0070] The mineral-imparting material (A) will be described below. The mineral-donating material (A) contains herbaceous plant materials consisting of herbaceous plants of the Asteraceae family and herbaceous plants of the Rosaceae family, as well as woody plant materials consisting of one or more woody plants selected from maple, birch, pine, and cedar. The parts to be used are appropriately selected from parts that are easy to leach mineral components, such as leaves, stems, flowers, and bark, and may be used as is or as a dried product. Although other herbs other than those of the Asteraceae and Rosaceae families may be included, it is preferable that only herbs of the Asteraceae and Rosaceae families are included.

[0071] The mineral-donating material (A) may be a mineral-donating material (A'). The mineral-donating material (A') is a dried and pulverized product of a plant of the Asteraceae family, which is prepared by mixing, as the herbaceous plant raw material, field thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) in proportions of 8 to 12% by weight, 55 to 65% by weight, and 27 to 33% by weight, respectively, drying the mixture, and pulverizing the mixture; The method uses dried and pulverized products of plants of the Rosaceae family, which are obtained by mixing, respectively, 17 to 23% by weight of Rosa multiflora (leaves and flowers), 8 to 12% by weight of Geum japonicum (leaves and stems), and 65 to 75% by weight of Rubus idaeus (leaves, stems, and flowers), drying the mixture, and pulverizing the mixture; a herbaceous plant material (A1) obtained by mixing the dried and pulverized product of the Asteraceae plant and the dried and pulverized product of the Rosaceae plant in a weight ratio of 1:0.8 to 1:1.2; As the woody plant raw material, maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) were mixed in proportions of 22 to 28% by weight, 22 to 28% by weight, and 45 to 55% by weight, respectively, and dried and then pulverized to obtain a woody plant raw material (A2). This mineral-imparting material is obtained by mixing herbaceous plant material (A1) and woody plant material (A2) in a weight ratio of 1:2.7 to 1:3.3.

[0072] Among the mineral-donating materials (A'), particularly preferred are herbaceous plant raw materials such as field thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) as the herbaceous plant raw materials, which are mixed in proportions of 10% by weight, 60% by weight, and 30% by weight, dried, and then pulverized, and herbaceous plant raw materials (A1) obtained by mixing, in a 1:1 (weight ratio), dried and pulverized products of plants of the Rosaceae family, which are mixed in proportions of 20% by weight, 10% by weight, and 70% by weight, dried, and then pulverized, and The woody plant raw material is preferably a mineral-imparting material obtained by mixing maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) in proportions of 25%, 25%, and 50% by weight, respectively, drying, and then pulverizing the mixture to obtain a dried and pulverized woody plant raw material (A2), and mixing the herbaceous plant raw material (A1) and woody plant raw material (A2) in a weight ratio of 1:3. As such herbaceous plant material (A1), "P-100 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used, and as woody plant material (A2), "P-200 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0073] In order to produce other mineral functional waters, the types of herbaceous plant raw materials (A1) and woody plant raw materials (A2) are changed. In addition, plant and animal species other than the herbaceous plant materials (A1) and woody plant materials (A2) can also be used as raw materials for mineral functional water.

[0074] (Mineral water (B) production equipment) Next, the structure, function, etc. of the mineral-containing water (B) production device 3 will be described with reference to FIGS. As shown in Figures 1 and 7, the mineral-containing water (B) manufacturing apparatus 3 includes a first water-passing container 51 to a sixth water-passing container 56 filled with different types of mineral-imparting material (B), a water supply path 57 connecting the first water-passing container 51 to the sixth water-passing container 56 in series, bypass water paths 51p to 56p connected to the water supply path 57 in parallel with the first water-passing container 51 to the sixth water-passing container 56, respectively, and water flow switching valves 51v to 56v provided at the branch points between each of the bypass water paths 51p to 56p and the water supply path 57.

[0075] The switching operation of the water flow switching valves 51v to 56v can be performed by operating six switching buttons 51b to 56b provided on an operation panel 58 connected to these water flow switching valves 51v to 56v by a signal cable 59. The six switching buttons 51b to 56b correspond to the six water flow switching valves 51v to 56v, respectively, so that operating any of the switching buttons 51b to 56b switches the water flow switching valve 51v to 56v with the corresponding number, thereby changing the water flow direction.

[0076] Here, the mineral-imparting materials (B) 51m to 56m can be preferably produced by mixing raw materials based on limestone, fossil coral, and seashells. First, the components contained in the limestone, fossil coral, and seashells are analyzed, and the amounts of silicon dioxide, iron oxide, activated carbon, titanium nitride, calcium carbonate, magnesium carbonate, and calcium phosphate are evaluated. Then, based on the content of each component, the limestone, fossil coral, and seashells are mixed to produce mineral-imparting materials (B) 51m to 56m. It is desirable to control the components contained in the mineral-imparting materials (B) 51m to 56m by adjusting the mixing ratio of limestone, fossil coral, and shells, but since the raw materials limestone, fossil coral, and shells may contain insufficient components depending on their place of origin, silicon dioxide, iron oxide, activated carbon, titanium nitride, calcium carbonate, magnesium carbonate, and calcium phosphate may be added as needed. In particular, activated carbon is rarely contained in limestone, fossil coral, and shells, so it is usually added separately.

[0077] As a mineral additive (B) 51m-56m, The mineral-providing material (B1) in the first water-passing container 51 is a mixture containing 70% by weight of limestone, 15% by weight of fossil coral, and 15% by weight of seashells, respectively; The mineral-providing material (B2) in the second water-passing container 52 is a mixture containing limestone, fossil coral, seashells, and activated carbon in amounts of 40 wt%, 15 wt%, 40 wt%, and 5 wt%, respectively; The mineral-providing material (B3) in the third water-passing container 53 is a mixture containing 80% by weight of limestone, 15% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-providing material (B4) in the fourth water-passing container 54 is a mixture containing 90% by weight of limestone, 5% by weight of fossil coral, and 5% by weight of seashells, respectively; The mineral-providing material (B5) in the fifth water-passing container 55 is a mixture containing 80% by weight of limestone, 10% by weight of fossil coral, and 10% by weight of seashells, respectively; If the mineral-donating material (B6) in the sixth water-passing container 56 is a mixture containing 60% by weight, 30% by weight, and 10% by weight of limestone, fossil coral, and shells, respectively, it is possible to obtain mineral-containing water (B) that exhibits excellent pest control effects when mixed with mineral-containing water (A).

[0078] In particular, the limestone, fossil coral, seashells, and activated carbon used in the mineral-imparting materials (B1) to (B6) are preferably the following (1-1) to (1-4).

[0079] (1-1) Limestone: Pebbles of about 3cm diameter made from crushed limestone mixed with volcanic deposits containing the following components: Calcium carbonate: 50% by weight or more Iron oxide: 3 to 9% by weight of iron Total of titanium oxide, titanium carbide, and titanium nitride: 0.8% by weight or more Magnesium carbonate: 7 to 10% by weight As such limestone, "CC-200 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0080] (1-2) Fossil coral: The following two types of fossil coral were mixed in a weight ratio of 1:9 and crushed to 3-5 mm particles. Fossil coral discovered about 100 meters underground, with its crystalline composition altered by pressure Fossil coral found on land near Amami Oshima, Okinawa (contains calcium carbonate, calcium phosphate, and other trace elements) As such fossil coral, "CC-300 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0081] (1-3) Shells: A granular material made by mixing equal amounts of abalone, tokobushi, and barnacles and crushing them to 3-5mm. As such a shell, "CC-400 (product number)" manufactured by Riken Technosystem Co., Ltd. can be suitably used.

[0082] (1-4)Activated carbon Activated carbon made from any raw material can be used, but activated carbon made from coconut shell is preferred. For example, "CC-500 (product number)" manufactured by Riken Technosystem Co., Ltd., which is made from coconut shell produced in Thailand, can be mentioned.

[0083] By operating the switch buttons 51b to 56b on the control panel 58 and switching the water flow selector valves 51v to 56v to the water container side, the water flowing through the water supply path 57 flows into the first to sixth water supply containers 51 to 56, which are located downstream of the operated water flow selector valves, and by switching the water flow selector valves 51v to 56v to the bypass water channel side, the water flowing through the water supply path 57 flows into the bypass water channels 51p to 56p, which are located downstream of the operated water flow selector valves. Therefore, by operating any of the switch buttons 51b to 56b and selectively switching the water flow selector valves 51v to 56v, it is possible to form mineral-containing water (B) 45 in which mineral components eluted from different mineral-imparting materials (B) 51m to 56m are selectively dissolved in the first to sixth water supply containers 51 to 56.

[0084] Next, the structure, functions, etc. of the actual mineral-containing water (B) production device 3 will be described with reference to Figures 8 to 11. Note that the aforementioned bypass water channels 51p to 56p, water flow switching valves 51v to 56v, operation panel 58, and signal cable 59 are omitted from Figures 8 to 10.

[0085] As shown in FIGS. 8 and 9, the mineral-containing water (B) manufacturing apparatus 3 includes first to sixth water-passing containers 51 to 56, which are generally cylindrical and mounted on a base 60, and a water supply path 57 connecting the first to sixth water-passing containers 51 to 56 in series. A raw water tank 63 for storing water W supplied from a mains water supply is disposed at the top of the base 60. The raw water tank 63 contains an inorganic porous body 64 that has the function of adsorbing impurities in the water W. A plurality of casters 61 and a level adjuster 62 are provided at the bottom of the base 60. The first to sixth water-passing containers 51 to 56, which are generally cylindrical, are mounted on the base 60, which has a rectangular lattice structure, with their respective axes 51c to 56c (see FIG. 9) maintained horizontally. The first to sixth water-passing containers 51 to 56 are detachable from the base 60.

[0086] As shown in Figure 10, the first through sixth water-passing containers 51 through 56 all have the same structure, with disk-shaped lids 51d through 56d attached to flanges 51f through 56f at both ends of the cylindrical main bodies 51a through 56a to form an airtight structure. A water inlet 57a, which communicates with the water supply path 57, is located at the bottom of the main bodies 51a through 56a when the axes 51c through 56c are horizontal. A water outlet 57b, which also communicates with the water supply path 57, is located at the top of the lid 51d through 56d furthest from the water inlet 57a, and a mesh strainer 57c is attached to the water outlet 57b. An automatic air valve 57d is attached directly above the water outlet 57b on the outer periphery of the main bodies 51a through 56a to release air from the first through sixth water-passing containers 51 through 56.

[0087] Water supplied from the upstream water supply path 57 passes through the water inlet 57a and flows into the first water supply container 51 to the sixth water supply container 56, and as it comes into contact with the mineral-imparting materials (B) 51m to 56m filled inside each, the respective mineral components are dissolved into the water, and the water contains mineral components corresponding to each mineral-imparting material (B) 51m to 56m, and flows out of the water outlet 57b into the downstream water supply path 57.

[0088] In the mineral-containing water (B) manufacturing apparatus 3 shown in Figures 8 to 10, by operating any of the switch buttons 51b to 56b on the operation panel 58 shown in Figure 7, water W from the raw water tank 63 can be passed through one or more of the first water-passing container 51 to the sixth water-passing container 56, thereby forming mineral-containing water (B) 45 in which the characteristic mineral components contained in the mineral-providing materials (B) 51m to 56m filled in the first water-passing container 51 to the sixth water-passing container 56, respectively, are selectively dissolved.

[0089] Furthermore, in the mineral-containing water (B) manufacturing device 3, the first water-passing container 51 to the sixth water-passing container 56 are connected in series by the water supply path 57, so that by continuously flowing water through the water supply path 57, it is possible to mass-produce mineral-containing water (B) 45 in which mineral components corresponding to the mineral-imparting materials (B) 51m to 56m in the first water-passing container 51 to the sixth water-passing container 56 are dissolved.

[0090] The mineral-containing water (B) 45 formed in the mineral-containing water (B) manufacturing apparatus 3 is sent into the mixing tank 46 via the water supply path 57x downstream of the sixth water supply container 56, and inside the mixing tank 46, it is mixed with the mineral-containing water (A) 44 produced in the mineral-containing water (A) manufacturing apparatus 2 shown in Figure 1 to form mineral functional water 47.

[0091] The blending ratio of mineral-containing water (A) to mineral-containing water (B) is determined appropriately taking into consideration the types of raw materials contained in mineral-containing water (A) and mineral-containing water (B) and the concentrations of the components that will be dissolved, but the weight ratio of mineral-containing water (A) to mineral-containing water (B) ([mineral-containing water (A)]:[mineral-containing water (B)]) is in the range of 1:5 to 1:20, preferably in the range of 1:7 to 1:12, and more preferably in the range of 1:10. If there is too little mineral-containing water (A) (too much mineral-containing water (B)), or if there is too much mineral-containing water (A) (too little mineral-containing water (B)), the active ingredients of the mineral functional water may be diluted, resulting in an insufficient desired effect.

[0092] Although the preferred embodiment of the method for producing the mineral functional water (a) according to the purifying material of the present invention has been described above, it is sufficient to produce the desired purifying material of the present invention (mineral functional water (a)), and various configurations other than the above preferred embodiment can be adopted, and it should not be considered as limiting. In particular, matters not explicitly disclosed in the disclosed embodiment, such as operating conditions, operating conditions, various parameters, dimensions, weights, volumes of components, etc., do not deviate from the scope of ordinary practice by a person skilled in the art, and values ​​that can be easily assumed by a person skilled in the art can be adopted. [Example]

[0093] The present invention will be explained in more detail below with reference to examples, but the present invention is not limited to these examples.

[0094] <1. Production of mineral functional water (a)> As the mineral functional water (a) for component (a) (mineral component derived from mineral functional water), mineral functional water CAC-717 (Terra Protect (product name), CAC-717 (product number), development product number CA-C-01) manufactured by Riken Techno Systems Co., Ltd. was used.

[0095] Mineral functional water (a) (CAC-717) was produced using the mineral functional water production apparatus described in the embodiment of the present invention and the above-mentioned production method, using the following raw materials and method. Note that this method corresponds to the mineral functional water production method described in Example 1 of Japanese Patent No. 5864010.

[0096] 1. Production of mineral-containing water (A) As raw materials for the mineral-donating material (A), "P-100 (product number)" manufactured by Riken Technosystem Co., Ltd. was used as the herbaceous plant raw material (A1), and "P-200 (product number)" manufactured by Riken Technosystem Co., Ltd. was used as the woody plant raw material (A2). "P-100" is a herbaceous plant material (A1) made by mixing the following dried and ground Asteraceae plants and dried and ground Rosaceae plants in a 1:1 (weight ratio), and "P-200" is the woody plant material (A2) described below. (A1) Herbaceous plant materials (dried herbaceous plants) (A1-1) Dried and crushed Asteraceae plants This product is made by mixing wild thistle (leaves, stems, and flowers), mugwort (leaves and stems), and Japanese silverleaf (leaves and stems) in proportions of 10%, 60%, and 30% by weight, respectively, drying, and then pulverizing. (A1-2) Dried and crushed Rosaceae plants This product is made by mixing wild rose (leaves and flowers), geum japonicum (leaves and stems), and rubus fruticosus (leaves, stems, and flowers) in proportions of 20%, 10%, and 70% by weight, respectively, drying, and then pulverizing. (A2) Woody plant materials (dried woody plants) Maple (leaves and stems), birch (leaves, stems, and bark), and cedar (leaves, stems, and bark) are mixed in proportions of 25%, 25%, and 50% by weight, respectively, dried, and then crushed.

[0097] The mineral-providing material (A), a 1:3 (by weight) mixture of herbaceous plant material (A1) and woody plant material (A2), was added to the raw mineral aqueous solution producing means 10 (see FIG. 2) of the mineral-containing water (A) producing apparatus 2 shown in FIG. 1 at a concentration of 10-15% by weight of water. A direct current (DC 8300 V, 100 mA) was passed through the conductive wire of the raw mineral aqueous solution producing means 10, generating a water flow in the same direction as the DC current in the water surrounding the conductive wire. Ultrasonic vibrations (oscillation frequency 50 kHz, amplitude 1.5 / 1000 mm) were applied to the water to form the raw mineral aqueous solution (A). The raw mineral aqueous solution (A) was then supplied to the downstream far-infrared generating means 43, where it was irradiated with far-infrared rays (wavelength 6-14 μm) to obtain the mineral-containing water (A) of the present example. In the mineral-containing water (A), the raw materials, the herbaceous plant material (A1) and the woody plant material (A2), were almost completely decomposed, and almost no solid matter was visible to the naked eye.

[0098] 2. Production of mineral-containing water (B) The raw material for mineral-imparting material (B) was a crushed and mixed mixture of limestone, fossil coral, seashells, and activated carbon. The raw materials for mineral-imparting material (B) and the mixtures used in the first to sixth water-passing vessels (mineral-imparting materials (B1) to (B6)) are as follows: (1) Raw materials (1-1) Limestone: "CC-200 (product number)" manufactured by Riken Techno Systems Co., Ltd. Pebbles of about 3cm diameter made from crushed limestone mixed with volcanic deposits containing the following components: Calcium carbonate: 50% by weight or more Iron oxide: 3 to 9% by weight of iron Total of titanium oxide, titanium carbide, and titanium nitride: 0.8% by weight or more Magnesium carbonate: 7 to 10% by weight (1-2) Fossil coral: "CC-300 (product number)" manufactured by Riken Technosystem Co., Ltd. The following two types of fossil coral were mixed in a weight ratio of 1:9 and crushed to 3-5 mm particles. Fossil coral found about 100 meters underground, with its crystalline composition altered by pressure. Fossil coral found on land near Amami Oshima, Okinawa (contains calcium carbonate, calcium phosphate, and other trace elements) (1-3) Shell: "CC-400 (product number)" manufactured by Riken Techno Systems Co., Ltd. Abalone, oysters, and barnacles mixed in equal amounts and crushed to 3-5mm granules (1-4) Activated carbon (used only in the second water supply container): "CC-500 (product number)" manufactured by Riken Technosystem Co., Ltd. Thai coconut shell activated carbon (2) Usage ratio for No. 1 to No. 6 water containers First water supply vessel: Mineral-adding material (B1): A mixture of limestone, fossil coral, and seashells at 70%, 15%, and 15% by weight, respectively. Second water supply vessel: Mineral-adding material (B2): A mixture of limestone, fossil coral, seashells, and activated carbon at 40%, 15%, 40%, and 5% by weight, respectively (equivalent to silicon dioxide and activated carbon). Third water container: Mineral-adding material (B3): A mixture of limestone, fossil coral, and seashells at 80%, 15%, and 5% by weight, respectively.

No. 6 water container: Mineral-adding material (B6): A mixture of limestone, fossil coral, and seashells at 60%, 30%, and 10% by weight, respectively.

[0099] In the mineral functional water production facility 1 shown in Figure 1, mineral-containing water (B) was obtained by passing water through the first to sixth water-passing vessels containing the mineral-providing materials (B1) to (B6). Each of (B1) to (B6) was 50 kg (300 kg in total), and the amount of water passed through was set to 1000 kg, with a flow rate of 500 mL / 40 s.

[0100] The mineral-containing water (A) and the mineral-containing water (B) prepared by the above method were mixed in a weight ratio of 1:10 to obtain mineral functional water (CAC-717).

[0101] When the mineral functional water was measured with a pH meter (Toko Chemical Laboratory glass electrode type hydrogen ion concentration indicator TPX-90), the pH was 12.5.

[0102] Figure 12 shows the spectral emissivity spectrum of mineral functional water (a) and the spectral emissivity spectrum (theoretical values) of a blackbody (measurement temperature: 25°C, wavelength range: 4-24 μm, reference carrier: ceramic powder). Figure 13 shows the emissivity ratio of mineral functional water (a) to a blackbody at 25°C. From Figure 13, the average emissivity ratios for wavelengths between 5-7 μm and 14-24 μm were calculated to be 91.7%.

[0103] <2. Manufacturing of purification materials> The purification material used in the experiment was obtained. The components (a) to (c) are as follows: Ingredient (a): Mineral components derived from mineral functional water (a) Ingredient (b): Humic substance derived from peat (Ukraine, fulvic acid:humic acid = 30:70) Component (c): Powdered metallic iron (particle size 0.5 mm or less)

[0104] Example 1 First, 20 parts by weight of the mineral functional water (a) was added to 60 parts by weight of humic substance (clay-like) and mixed thoroughly to obtain a clay-like solid (semi-solid). Next, 20 parts by weight of iron powder was added and mixed to obtain the purification material (granular material) of Example 1. Note that when the iron powder was kneaded, the clay-like solid gradually hardened and became granular.

[0105] (Comparative Example 1) Without using mineral functional water (a), 60 parts by weight of humic substance was mixed thoroughly with 20 parts by weight of water to obtain a liquid. Next, 20 parts by weight of iron powder was added and kneaded to obtain the purification material (granular material) of Comparative Example 1.

[0106] <2. Evaluation> A demonstration experiment was carried out on the purifying material of the present invention in the following manner: The purifying materials of Example 1 and Comparative Example 1 described above were used.

[0107] (Preparation of aqueous samples for evaluation) An appropriate amount of purified water was added to commercially available milk to prepare diluted milk water with a COD concentration of 40 ppm, which was used as an aqueous sample for evaluation (a substitute for water containing organic matter to be treated).

[0108] (Sample solution 1) 20 g of the purification material of Example 1 was added to 500 mL of an aqueous sample for evaluation, and the mixture was stirred at 200 rpm for 15 minutes to obtain a sample solution of Experimental Example 1.

[0109] (Sample solution 2 (control)) Further, sample solution 2 for a control experiment was obtained in the same manner as sample solution 1, except that the purification material of Comparative Example 1 was used instead of the purification material of Example 1.

[0110] <Light irradiation test> The COD value and ferrous iron (Fe ) content of the sample solutions (sample solutions 1 and 2) after irradiating them with a xenon lamp (specification BSO-X150) for 12 hours were measured. 2+ ) concentration and trivalent iron (Fe 3+The concentration of the solution was measured using the following method. The xenon lamp was then turned off and the solution was left to stand in a dark room for 12 hours, after which the concentration was measured in the same manner. Stirring was only performed during irradiation with the xenon lamp.

[0111] (Measurement method) COD measurement: Potassium permanganate oxidation method Dissolved iron concentration measurement: JIS K 0102 57.1 reduced o-phenanthroline absorptiometry method Divalent iron (Fe 2+ ) Concentration measurement: ο-phenanthroline absorptiometry Trivalent iron (Fe 3+ ) Concentration measurement: sulfosalicylic acid absorption spectrophotometric method

[0112] Table 1 shows the COD values ​​and dissolved iron concentrations (Fe 2+ and Fe 3+ total), divalent iron (Fe 2+ ) concentration, trivalent iron (Fe 3+ The concentrations of dissolved iron, divalent iron, and trivalent iron were rounded to the nearest whole number.

[0113] [Table 1]

[0114] As shown in Table 1, a comparison of the results at the start and 12 hours after light irradiation (first time) showed that the COD values ​​decreased to the same extent in both sample solution 1 using the purification material of Example 1 and sample solution 2 using the purification material of Comparative Example 1 (control sample), and the trivalent iron concentration increased to the same extent along with the decrease in the divalent iron concentration. From these results, it was determined that the Fenton reaction proceeds when irradiated with light, and that the hydrogen peroxide produced by the humic components in the sample solution is converted into trivalent iron by the action of divalent iron, generating active oxygen hydroxyl radicals, and that the COD values ​​of both samples decreased to the same extent due to oxidative decomposition by these hydroxyl radicals.

[0115] On the other hand, in the measurement after 12 hours of standing in a dark room without light irradiation, a decrease in the trivalent iron concentration and an increase in the divalent iron concentration were confirmed in Sample Solution 1 using the purification material of Example 1, and both concentrations returned to the same level as at the start. This confirmed that the purification material of Example 1 can reduce trivalent iron to divalent iron in the dark. In contrast, in sample solution 2 using the purification material of Comparative Example 1 (control sample), the divalent iron concentration and the trivalent iron concentration showed almost no change from the values ​​12 hours after light irradiation.

[0116] Next, when light irradiation was carried out again, as shown 12 hours after light irradiation (second time), it was confirmed that the COD value of sample solution 1 using the purification material of Example 1 decreased, and the concentration of trivalent iron increased along with the decrease in the concentration of divalent iron. From the above results, it was confirmed that the purification material of Example 1 can reduce trivalent iron to divalent iron in the dark, and that the generated divalent iron can be used to repeatedly and continuously carry out the Fenton reaction by irradiating it with light again. [Industrial Applicability]

[0117] The purifying material of the present invention has an excellent decomposition effect on organic matter and can maintain this effect for a long period of time, and therefore can be suitably used to improve the quality of bottom sediments and water in contact with them.
