Description

  The present invention relates to a method and apparatus for generating water (functional water) containing ionic species generated from the solute by reacting active oxygen species generated by a photocatalyst with a solute in an aqueous solution.

Reactive oxygen species are widely distributed in nature and in the living body, and their strong oxidizing power causes cell membrane damage and is known to have a bactericidal ability. In general superoxide anion radicals from the original active oxygen species (O ₂ ^-), hydrogen peroxide (H ₂ O _2), refers to oxygen species such as hydroxyl radicals ^(· OH) and singlet oxygen ⁽¹ O _2), In a broad sense, it indicates lipid peroxide (LOOH, LOO ^· ), halogenated oxygen (ClO ⁻ ), and nitric oxide radical (NO ^· ) identified as an endothelium-derived relaxing factor. It has been found to be a dissimilar substance for vascular endothelial cell injury and is treated as an in vivo disorder transmitter. Its characteristics have been elucidated from the process of investigating the cause of the disorder, and it is clear that superoxide dismutase (SOD) and NO ^· are stored in the body to eliminate O ₂ ⁻ and maintain homeostasis.

  However, in recent years, it is known that trace amounts of reactive oxygen species are expressed when plants germinate, and its role in nature is still being elucidated, and measurement and quantification in vitro is difficult. Similarly, there are negative ions that exist in nature and are sterilized by their oxidizing power. In a broad sense, it is considered that reactive oxygen species are also included in some of them, but among the slightly charged substances contained in the air, they are considered negatively charged. The identification of the substance and its metabolic process have not yet been clarified. In the production process, it is thought that it is an ion of oxygen molecule or an ion of nitric acid molecule after a certain time, but this is not all.

  Of the substances listed as reactive oxygen species, hydrogen peroxide is relatively stable and widely used for sterilization and anthelmintic. When used to control ectoparasites (eg, worms, skinworms, etc.) infested with cultured fish, hydrogen peroxide is used at a high concentration of 200 to 3000 ppm or more. The effective hydrogen peroxide concentration of Paramecium caudatum, which is a representative example of unicellular protozoa, varies depending on the species, but it is 10 ppm for Paramecium aurelia complex, even though it can be killed by Paramecium caudatum. A high concentration of 100 ppm is required for P. bursaria. That is, the concentration at which the action of the hydrogen peroxide solution appears varies depending on the target species.

  However, in reality, reactive oxygen species do not exist in hydrogen peroxide alone, but exist together with other active oxygen species, and are considered to be acting as various ions in the reaction process, and interact with other ions. It can be assumed that sterilization and protozoan anthelmintics can be achieved even at low concentrations due to the action.

On the other hand, the active oxygen species generated by irradiating the photocatalyst with light to excite the photocatalytic reaction are sterilized near the surface of the photocatalyst (usually 40 nm), sterilizing microorganisms, and various organic chemistry. It is known to have the ability to oxidize substances. That is, albeit only in the immediate vicinity of the photocatalyst, these superoxide anion radicals (O ₂ ^-), hydroxyl radicals, (OH ·) a highly reactive active oxygen species such as melts in contact with the water, microorganisms Ya It has been said that it is possible to mutate the viability and proliferation functions of microorganisms and viruses by mutating viral cell membranes, functional proteins and genes.

In order to sterilize microorganisms present in the water, for example, as shown in FIG. 12, an ultrasonic humidifier body 51, a water tank 52 provided in the ultrasonic humidifier body 51, and a bottom of the water tank 52 An ultrasonic transducer 53 provided and a near-ultraviolet irradiation device 54 for irradiating near-ultraviolet rays on the upper part of the water tank 52 are disposed, so that the water stored in the water tank 52 can be sterilized. However, the effect of this system is limited to sterilization, and the anthelmintic effect on amoeba species inhabiting the main target Legionella is not clear. Since the distance between the photocatalyst and the ultraviolet light source is separated through the free surface of water, the amount of ultraviolet rays that reach is extremely small, and sufficient oxygen free radicals or hydroxyl free radicals cannot be obtained, which is as weak as an ultrasonic humidifier. Ultrasonic vibration does not cause damage to protozoa, and as a result, it may diffuse a large amount of fumed cells of Legionella.

As described above, the above-described water sterilization apparatus is not limited to the reaction of only active oxygen species, and the subsequent secondary reaction cannot be derived, and the functional water generated until the extermination of protozoa has not been generated. In addition, since the oxidation ability lasts for a very short time of 10 ⁻⁶ seconds, the reaction phase is considered to have been obtained only in a very limited region in the very vicinity of the photocatalyst and used. Anatase-type titanium oxide in which an anatase-type titanium oxide or a photosensitizer is mixed in a glass sintered body cannot fully exhibit its effect and has not yet been put into practical use.

  Further, the method for treating cultured fish with the hydrogen peroxide solution (generally referred to as a hydrogen peroxide water bath) has the strong oxidizing power of hydrogen peroxide to the cultured fish itself. In other words, rather than recovering the pathological condition by reducing the number of parasites etc. in the cultured fish body, it is undeniable that the fish that became vulnerable to the disease are slaughtered with the parasites and only strong fish are alive. It was a thing.

  Vulnerable fish that have died due to hydrogen peroxide spraying in this way can reduce the yield of cultured fish and reduce aquaculture efficiency, so that parasites can be controlled more safely than parasite-infected fish. If it becomes possible, the increase in catch will be obvious, and not only will the distribution price decline, but also food safety will be ensured.

  In addition, the hydrogen peroxide to be sprayed requires an effective concentration in seawater as high as 200 to 3000 ppm, and although it is diluted, it flows into the ocean as it is with conventional chemical bathing methods such as formalin bath.・ Dispersed and dumped. This has an effect on other marine organisms other than aquaculture, and it is difficult to say that it is favorable in terms of environmental influences, and the influence on the human body is still unclear.

  Moreover, in order to bring about the anthelmintic effect, a large amount of hydrogen peroxide preparation is required, and the cost and labor required for transporting it impose a tremendous burden on those engaged in work. Therefore, there has been a demand for a functional water generating apparatus and an insecticidal method that do not affect the environment without using drugs remaining in the water and without damaging cultured fish.

  That is, in order to use the active oxygen species for the purpose of sterilization or anthelmintic, it is important to determine the concentration according to the purpose of use by controlling the amount of target ions.

  Therefore, the present inventor can generate water sufficiently containing reactive oxygen species, and can perform sterilization of microorganisms and parasite deworming, and can maintain its strong oxidizing ability, thereby saving energy. Conduct research on photocatalytic water generation equipment that can be applied to various devices with electric power and compact, and adjust the photocatalyst body, the amount of ultraviolet rays, the frequency of ultrasonic waves, the output, and the type and amount of mixed gases. As a result, the present invention has been achieved as a product capable of controlling the expression of induced reactive oxygen species and ions, which is safer and does not cause adverse effects on the human body and the environment.

  In order to solve the above-mentioned problems, the functional water according to the present invention is a functional water obtained by reacting an active oxygen species generated by a photocatalyst irradiated with an ultraviolet ray with an aqueous solution containing ions into the functional water.

  In the functional water generating method according to claim 1, the active oxygen species generated by the photocatalyst irradiated with ultraviolet rays is imparted to the aqueous solution containing ions, and the strong oxidizing power can be maintained by reacting with the ions. As a result, functional water can be taken out of the functional water generating device, and the protozoa can be dewormed in another place while maintaining its strong oxidizing power. In addition, since the protozoan anthelmintic is possible, it is possible to sterilize Legionella bacteria grown in the body of protozoa such as amoeba.

  Moreover, in the functional water generating apparatus according to claim 2, the protozoan produced by reacting with the active oxygen species generated in the photocatalyst by ultraviolet irradiation and / or the aqueous solution passing through the apparatus is produced secondarily.

  Moreover, in the functional water generating apparatus according to claim 4, since the photocatalyst is disposed around the light source, the photocatalyst can be effectively irradiated with ultraviolet rays emitted from the light source, and the photocatalyst is active. Oxygen species can be generated sufficiently.

  In the functional water generating device according to claim 5, since the diffusing means for diffusing the active oxygen species generated on the surface of the photocatalyst body in water is disposed in the container, the surface of the photocatalyst body enters the water. The active oxygen species can be released quickly.

  Further, in the functional water generating apparatus according to claim 6, the diffusion means is an ultrasonic wave of 100 kHz or higher by an ultrasonic vibrator and / or a water flow by an underwater fan, and moves the photocatalyst and / or water. Therefore, the active oxygen species can be released more rapidly from the surface of the photocatalyst into the water.

  In the functional water generating apparatus according to claim 9, the photocatalyst is a glass fiber, a ceramic fiber, or a non-woven fabric, and the surface thereof is covered with a titania thin film, so that the surface area is increased. In addition, the photocatalyst body can be manufactured at a relatively low cost, and the functional water generator can be manufactured at a low cost.

  Further, in the functional water generating apparatus according to claim 10, the photocatalyst is a metal fiber body having an alumina film formed on the surface in advance, and a titania thin film is densely formed on the surface, so that it is efficiently activated.

  Moreover, in the functional water generating apparatus according to claim 11, the alumina coating of the metal fiber body is heated at a rate of 5 ° C./min or less to a temperature half the melting point of the aluminum-based metal constituting the metal fiber body. Then, since it was formed by heating to just before the melting point of the aluminum-based metal, the alumina coating on the metal fiber body can be densely formed, and the adhesion between the titania thin film and the metal fiber body is improved. be able to. That is, the durability of the photocatalyst in water can be further improved.

  Moreover, in the functional water generating apparatus according to claim 12, the functional water is obtained by mixing at least one of oxygen gas, ozone gas, chlorine gas, nitrogen monoxide gas, and ammonia gas in the circuit. It can be set as the aqueous solution containing this.

  The functional water generator according to the present invention includes a container containing an aqueous solution in which ionic species are generated by reacting with active oxygen species generated by the photocatalyst, a photocatalyst disposed by being immersed in the aqueous solution in the container, And a light source for irradiating the photocatalyst with ultraviolet rays.

  Here, the functional water means water containing ions derived from the solute produced by reacting a solute in an aqueous solution with active oxygen species generated in the photocatalyst.

  Therefore, by configuring the functional water generating device as described above, the active oxygen species generated by irradiating the photocatalyst with ultraviolet light from the light source are diffused in water, and the active oxygen species are reacted with the solute in the aqueous solution. Thus, water (ionic water) containing ionic species generated from the solute can be generated.

  Here, the solute in the aqueous solution may be a liquid or solid dissolved in water, or a gas dissolved in water. For example, any one of oxygen gas, ozone gas, chlorine gas, nitric oxide gas, and ammonia gas may be mixed and dissolved. At that time, in order to increase the degree of saturation in mixing the gas and the solute, it may be agitated and mixed in advance by ultrasonic vibration, and the dissolved concentration is increased by mixing this gas and water, and finer bubbles are generated. The ultrasonic frequency used for bringing the photocatalyst fiber into contact with the surface after forming the shape is not specified, and a 16 kHz low frequency vibrator having higher stirring ability may be used.

  Furthermore, when a very unstable gas such as ozone gas or nitrogen monoxide gas is used, the film surface electrons on the surface of the photocatalyst described later become unstable, and the photocatalytic reaction is more easily excited.

  Further, the aqueous solution is not a solution in which a solute is intentionally added to water, and may already contain a solute such as seawater or rainwater. Examples of the solute include oxygen, chlorine, ammonia, and salts such as sodium chloride, magnesium chloride, magnesium sulfate, calcium sulfate, potassium sulfate, potassium chloride, calcium carbonate, and magnesium bromide.

  The use of the functional water thus generated is not particularly limited, and can be used in various fields such as sterilization, sterilization, anthelmintic, washing, and drinking.

  Since the titania thin film having photocatalytic activity is formed on the surface of the photocatalyst, the titania thin film is excited and activated by the ultraviolet light emitted from the ultraviolet lamp hitting the titania thin film. .

On the surface of the activated photocatalyst, the energy of the ultraviolet rays (hν) emitted from the ultraviolet lamp excites the titanium oxide (TiO ₂ ) constituting the titania thin film, and the water that satisfies the functional water generator is the photocatalyst. Reactive oxygen species are generated by contact with. A reaction in which active oxygen species are generated by contact of water with the excited photocatalyst is referred to as a primary reaction.

Usually, in the case of pure water H ₂ O, the primary reaction is considered to be performed as follows.

^{_{TiO 2 + hν → e - +}} h + VB
h + VB → h + tr
_{^{O 2 + e - → O 2}} · -
O _2- + h + VB (h + tr) → O ₂
^{OH - + h + VB → OH} ·
Further, when the oxygen or ozone in water is contained in large quantities, these reactions are accelerated, a large amount of O ₂ · ^- the possible and OH · is generated.

Here, when water containing chlorine ions intervenes, it is considered that the following reaction is activated.
_{^{2Cl - + O 2 + e -}} → 2ClO -
If water containing a large amount of nitric oxide gas is present,
NO + e ^- → · NO
_{^{· NO - e - → NO 2}} -
_{^{2NO 2 - - 2e - → 2}} · NO 3 -
^{_{· NO + NO 2 - → N}} 2 O 3
^{_{· NO + O 2 · - →}} · ONOO -
^{· ONOO - + H + → HOONO} → OH ·
And become more powerful cytotoxic ions.

  Next, since the reactive oxygen species generated in the primary reaction have high reactivity, it reacts with active oxygen species, substances and ions dissolved in water, and generates further products. . Here, the reaction that the active oxygen species generated in the primary reaction causes with substances or ions dissolved in water is called a secondary reaction.

  In the secondary reaction, for example, the following reaction is considered to occur.

_{^{O 2 - + O 2 - +}} 2H + → H 2 O 2 + O 2 ( generation of hydrogen peroxide)
Except for ultrapure water containing no other ions, water existing in a normal environment is considered to contain a trace amount of element ions. In particular, since tap water is sterilized with chlorine, the following secondary reaction is considered to have occurred.

_{HCl + O 2 · - + OH} - → ClO 2 + H 2 O ( generation of chlorite)
^{_{ClO 2 + 2OH - → HOCl +}} H 2 O ( product of hypochlorous acid)
In addition, in an environment where organisms such as rivers and seawater exist, ammonia is contained, and it is considered that the following secondary reaction occurs similarly.

_{^{NH 3 + OH - → NO -}} + 2H 2 O ( nitric oxide ion generation)
In addition to the reactions described above, it is a matter of course that more secondary reactions are carried out, but in the functional water, the secondary reactants (ionic species) thus generated are artificially large quantities. Will be included.

  In particular, when the water to be brought into contact is seawater or an aqueous solution in which a predetermined substance is dissolved, these ionic species can be generated over many kinds.

  Moreover, the ultraviolet-ray for exciting a photocatalyst body can utilize the ultraviolet-ray contained in sunlight and / or artificial light. For example, when sunlight is used, it is possible to reduce the cost for exciting the photocatalyst, and it is possible to irradiate the photocatalyst with stronger ultraviolet energy obtained by artificial light. When irradiating light to a photocatalyst disposed in water, a reflector such as an optical fiber or a prism is used to direct sunlight or artificial light into the water and directly irradiate the photocatalyst in water. May be.

  The photocatalyst may be titanium oxide (titania) having a rutile or anatase crystal phase.

  The photocatalyst using titanium oxide may be a highly efficient photocatalyst having an enlarged surface area by applying dip coating with titania to a fibrous carrier.

  Here, as the fibrous carrier, for example, a metal containing aluminum such as 1000s to 7000s (hereinafter, also referred to as an aluminum-based metal) can be suitably used, and alumina formed by heating the aluminum-based metal. By using a metal fiber body, titania is densely coated on the carrier, so that the durability can be further improved.

  In particular, by using an aluminum-based metal containing silica, the titania thin film formed on the fiber is strongly bonded to the silica, thus forming a photocatalyst with excellent corrosion resistance, heat resistance, and durability. can do.

  The alumina metal fiber body may be formed by heating a metal containing aluminum forming the carrier to a predetermined temperature at a rate of 5 ° C./min or less, and then heating to just before the melting point of the metal fiber body.

Here, the predetermined temperature can be calculated by the following calculation formula.
Predetermined temperature (° C) = melting point temperature of metal containing aluminum (° C) ÷ 2

  More specifically, when a metal fiber body whose surface is covered with alumina is used as a carrier and subjected to dip coating processing to form a titania thin film, it becomes possible for titania to form a thin film densely on the alumina coating, A titania thin film can be formed without unevenness.

  When a uniform titania thin film is excited by ultraviolet rays, a photocatalytic reaction can be performed more efficiently, and more active oxygen species can be generated.

  Here, the alumina coating of the metal fiber body is such that the aluminum-based metal fiber is at a temperature of about half the melting point at a rate of 5 ° C./min or less (for example, 1 to 5 ° C./min, preferably 4 to 5 ° C./min). After slowly heating to oxidize the surface, it is heated to just before the melting point to oxidize to a deeper layer so as to form an artificial oxide film that sufficiently exhibits the function as an alumina fiber. In addition, an aluminum-type metal shows both aluminum and an aluminum alloy.

  That is, while protecting the metallic fiber body using an oxide film formed by heating the aluminum-based metal fiber body to a temperature about half the melting point of the aluminum-based metal, it is heated to just before the melting point to form a homogeneous alumina coating. It is what is formed. Furthermore, the metal fiber body can form an extremely stabilized oxide film by heating to the melting point or higher of the aluminum-based metal constituting the metal fiber body. Therefore, when a titania thin film is formed on this metallic fiber body, the adhesion between the titania thin film and the metallic fiber body can be enhanced.

  In addition, an oxide film is formed by heating to about half the melting point of the aluminum-based metal, and while heating the metal fiber body with this oxide film, heating to just before the melting point, and then firing beyond the melting point The metal fiber body can maintain the fiber form even when the temperature rises to the vicinity of the melting point of alumina, and exhibits the function as an alumina fiber as the fiber capacity. In order to obtain a rutile type fiber that causes a rutile type photocatalytic reaction in the photocatalyst body, the fiber needs to be baked to 750 ° C. or higher exceeding the melting point of the aluminum-based metal in the dip coating process. The formed extremely stable alumina metal fiber body can make a rutile type titania fiber having high adhesion to the titania thin film while maintaining the fiber form.

  Thus, by increasing the adhesion between the titania thin film and the metal fiber body, the titania thin film does not peel from the metal fiber body even in an ultrasonic environment, and the photocatalyst body has sufficient durability. it can.

  Since the alumina metal fiber body is formed by heating the fiber body made of a metal containing aluminum in this way, the alumina metal fiber body having a dense alumina coating can be obtained. Can be further improved.

  Here, as a means for diffusing active oxygen species into water, for example, ultrasonic waves can be used.

  The effect of the ultrasonic vibrator used here is that the fibrous photocatalyst is vibrated finely, and the generation of active oxygen species generated by the photocatalytic reaction can be performed more smoothly, and is also induced on the photocatalyst fiber. Electrons generated by the photocatalytic reaction can be easily migrated.

  In addition, the active oxygen species generated on the fiber of the photocatalyst by this electron is released into the water because the flow rate of water flowing on the fiber surface increases dramatically when the fiber moves at high speed by ultrasonic vibration. Things will be possible.

  That is, it is presumed that these ultrasonic waves may promote the release of the active oxygen species from the photocatalyst and may enhance the reaction with each other by the mutual interference action of the ultrasonic wave and the ultraviolet wavelength.

  As the ultrasonic vibrator, for example, it is recommended to use an atomizing ultrasonic vibrator (high-frequency ultrasonic vibrator) that generates high-frequency ultrasonic waves (generally said to be 500 kHz or more).

  Although the high-frequency ultrasonic vibration generated from the atomizing ultrasonic vibrator has a low fiber cleaning ability, it has a sufficient force to shake off electrons, active oxygen species, and the like generated in the photocatalytic reaction into water.

  Moreover, the ultrasonic wave to be used may be a medium frequency ultrasonic wave (100 to 500 kHz).

  When using medium-frequency ultrasonic waves emitted from a medium-frequency ultrasonic transducer, when the ultrasonic wave hits the fibrous photocatalyst, the diffractive property of the sound wave increases, and the water in the sealed container is further stirred. Although it can be strengthened and active oxygen species can be efficiently released from the photocatalyst, the deterioration of the photocatalyst fiber is unavoidable as compared with the high-frequency vibrator.

  However, due to the action of the medium frequency ultrasonic wave, it is possible to produce a cleaning effect on a substance having a relatively large molecular weight such as a dirt component adhering to the fiber. However, low-frequency ultrasonic waves of 100 kHz or less are preferably not used because they may cause deformation of the photocatalyst and damage to the catalytic reaction surface formed on the photocatalyst.

  Further, as a means for diffusing the active oxygen species into water, even if the photocatalyst is mechanically moved, the active oxygen species can be efficiently contained in water.

  It is speculated that these ultrasonic waves may promote the release of the active oxygen species from the photocatalyst and may enhance the reaction with each other by the mutual interference action between the ultrasonic wave and the ultraviolet wavelength.

  By the way, in the functional water production | generation apparatus which concerns on this invention, the effect of functional water is provided at the time of the production | generation apparatus first passage, and the water which passed has the function for a fixed time, but when there is a lot of water which needs processing. A circulation process may be performed. At that time, there is a possibility that the water to be treated itself is mixed with protozoa that are subject to sterilization and anthelmintic, and at the upstream or downstream of the site where the photocatalytic reaction occurs (for example, in the vicinity of the photocatalyst) or at the same position, You may irradiate together with the ultraviolet-ray of a wavelength of 254-265 nm by a germicidal lamp.

  That is, the aqueous solution to be contacted with the photocatalyst body may be treated with a germicidal lamp, the functional water obtained by the photocatalyst body may be treated with a germicidal lamp, and the treatment with the germicidal lamp is performed in the vicinity of the reaction of the photocatalyst body. You can go.

  In other words, UV light having a wavelength of 254 to 265 nm is irradiated to water that is in contact with the photocatalyst body, water that is in contact with the functional water or the photocatalyst, and cell membrane protein degeneration is caused to microorganisms in each water, The bactericidal effect against microorganisms and bacteria in the generated functional water and the anthelmintic effect against parasites can be enhanced.

  Originally, cell membrane alteration of microorganisms by germicidal lamps is considered to be a mutational disorder in the DNA of microorganisms by ultraviolet rays, but when ultraviolet irradiation is interrupted, nucleic acids are repaired and regenerated, so-called photorecovery occurs, and bacteria are regenerated and revived. Has been.

  However, microorganisms such as bacterial bodies that have been damaged by DNA and weak protozoa are supplied to the functional water generator and react with reactive oxygen species (primary reactants) generated in the photocatalyst, and solutes in aqueous solutions. By reacting with ionic species (secondary reactant) generated by reaction with reactive oxygen species, strong oxidative ions invade from the damaged cell membrane and oxidatively decompose, resulting in weak cells and protozoa It can cause fatal damage to microorganisms such as mosquitoes and reliably sterilize microorganisms in water.

  Cell membranes of microorganisms damaged by the combined use of germicidal lamps undergo oxidative transformation with functional water, show strong bactericidal power against bacteria with strong cell membranes such as capsules, nucleic acid damage is permanent, and light recovery Can no longer be expressed.

  In particular, in a state in which a functional water generating device is installed in a water tank or the like and a circulation system is configured, it is possible to obtain more functional water.

  By the way, the functional water generated by the functional water generating apparatus according to the present invention is particularly necessary for the field that requires sterilization of microorganisms, the field that requires the parasites of fish body parasites, and the control of protozoa such as amoeba. It exerts its tremendous effect in the field. As described above, the effect of reactive oxygen species in living organisms varies depending on the species, but protozoan anthelmintices, which are larger than bacteria, require stronger oxidizing power than sterilization, sterilization, and cleaning applications. Become. Therefore, according to this functional water generator capable of anthelmintic, microorganisms can be effectively sterilized by bringing bacteria into contact with the generated functional water and sterilizing and sterilizing.

  This sterilization method is not particularly limited as long as microorganisms can be brought into contact with functional water, and the microorganisms are supplied to the functional water generator together with water so that the microorganisms are brought into contact with active oxygen species or ion species inside the device. May be sterilized.

  In addition, the functional water generation device can decompose organic substances in addition to sterilization and sterilization by configuring a cleaning system so that the generated functional water is brought into contact with the object to be cleaned. In addition, physical stains such as apparent stains can be removed.

  Examples of the object to be cleaned here include dentures, medical instruments, tableware, vegetables, precision instruments, toilets, fabrics, seeds, and the like, but are not particularly limited thereto.

  Next, a functional water generator for anthelmintic insects will be described.

  According to the functional water generating apparatus according to the present invention, the active oxygen species generated by irradiating the photocatalyst with ultraviolet light from the light source is diffused in water, thereby imparting the function of the active oxygen species to the water. It is also possible to provide a functional water generating system for anthelmintics that can carry out the parasitizing of fish parasites using an oxidation reaction.

  That is, as in the above-described functional water generation system for sterilization, the functional water is brought into contact with the parasite to carry out the parasitism of the parasite adhering or parasitic on the fish.

  Here, the water used in the functional water generating system for anthelmintic is not particularly limited, and for example, it can be used regardless of fresh water, seawater, or purified water.

  The functional water generating system for anthelmintics capable of carrying out the parasites of fish parasites may be provided with a germicidal lamp capable of producing a sterilizing effect.

  By the way, the functional water generating system for anthelmintic insects capable of carrying out the parasitizing of these fish parasites may be configured by attaching a functional water generating device to an aquarium or the like. It is also possible to use a functional water generating system for anthelmintic worms that can carry out the parasitizing of fish parasites.

  That is, according to the former example, for example, by attaching a functional water generating device to a water tank containing water and fish, water in the water tank is supplied to the functional water generating device, and active oxygen species and ion species are supplied. By returning the water containing the water to the aquarium again, the water containing the active oxygen species and the ionic species can be brought into contact with the fish, so that a functional water generating system for anthelmintic can be formed that can insect the parasite of the fish body.

  By using the functional water generating device according to the present invention, a functional water generating system for anthelmintic insects is used to parasitize fish skin (Lepeophtheirus salmonis, Benedenia seriolae, Benedenia skii, Neobenedenia girellae, Entobdella soleae, etc.), fish Worms derived from ectoparasites such as the hemp (Heterraxine Heterocerca, Zeuxapta japonica, Bivagina tai, Heterobothrium okamotoi, Heterobothrium tetrodonis, Neoheterobothrium hirame, Neoheterobothrium affine) Can be prevented or treated.

  At this time, while controlling the water temperature within ± 5 ° C, preferably within ± 3 ° C, preferably within ± 3 ° C of the environment temperature of the fish to be anthelmintic, it is possible to control the parasite effectively while controlling the parasite. You can desperate without putting the burden on the fish.

  In addition, by adjusting the dissolved oxygen concentration in water to 12 mg / L or less, preferably 10 mg / L or less, it is possible to improve the contact efficiency between the photocatalyst and oxygen while preventing the anthelmintic target fish from being weakened by oxygen damage. Thus, the anthelmintic effect can be brought out more suitably.

  Hereinafter, the present invention will be described in more detail with reference to examples.

  In FIG. 1, the functional water production | generation system A which concerns on a present Example is shown. This system can increase the production amount of functional water by using this functional water generating device 1 as a basic unit and arranging a plurality of basic units in series and in parallel according to the purpose of use.

    The water tank 33 stores water 31 in advance, and this water 31 is sent to the functional water generator 1 through the water supply pipe 3 by driving a water supply pump 32 immersed in the water 31. ing.

  Then, the water 31 treated by the functional water generator 1 becomes functional water containing abundant active oxygen species and ion species, passes through the drain pipe 10, flows down from the drain port 11, and enters the water tank 33 again. It is configured to return.

  Next, the further detailed structure of the functional water generating apparatus 1 is demonstrated using FIGS.

  As shown in FIG. 2, the functional water generating apparatus 1 has a sealed container 6 including a box-shaped container body 7 having an upper opening and a lid body 8 that closes the upper opening of the container body 7. ing.

  The material constituting the sealed container 6 is not particularly limited, and may be made of metal, resin, plastic, etc., but is preferably corroded by a material that is not easily deteriorated by ultraviolet irradiation, water, or seawater. It is good to use a material with difficult corrosion resistance. By forming the container body 7 and the lid body 8 with such a material, the life of the functional water generator 1 can be extended. In the figure, the sealed container 6 is made of plastic.

  Further, a drain hose connection part 40 for taking out functional water generated inside the sealed container 6 is provided on the upper side surface of the container body 7. On the other hand, a water supply pipe 3 provided so as to extend outward is provided on the lower side surface of the container main body 7, and an open end of the water supply pipe 3 is a water supply for supplying water into the sealed container 6. Mouth 2 In FIG. 1, a water supply pump 32 is connected to the water supply port 2 so that water 31 is fed into the functional water generator 1. In this embodiment, the water supply pump 32 uses (Eloca PF-380, flow rate 6.2 L / min).

  A hollow precursor supply pipe 4 that allows a substance (precursor) that becomes a solute in an aqueous solution to flow is connected to the middle of the water supply pipe 3, and this connection portion is used as a precursor supply section 5. .

  Here, as a means for supplying the precursor to water, the precursor supply pipe 4 is connected to the water supply pipe 3 so that oxygen is efficiently diffused into the water by the water flow in the water supply pipe. It is not particularly limited as long as the precursor can be included in the water 31 supplied to the apparatus 1. For example, the precursor supply pipe 4 may be directly connected to the functional water generating apparatus 1.

  In addition, before supplying to the functional water generator 1, in order to stir and mix the water 31 and the precursor, another reaction tank is placed, a low frequency ultrasonic vibrator is placed in the same part, The dissolution concentration may be increased.

  Further, the precursor that flows through the precursor supply pipe 4 may be any of liquid, gas, and solid.

  When the precursor is air or ozone, a gas having a higher oxygen concentration is preferable. The higher the concentration of oxygen supplied to water, the more efficiently oxygen can be contained in water, the amount of active oxygen species generated in the photocatalyst can be increased, and the amount of ionic species generated can be increased. it can.

  Furthermore, as a method for increasing the dissolved oxygen concentration of the water 31, for example, a foaming agent that reacts with water and foams to generate oxygen in the bubbles can be used.

  An ultrasonic oscillator 12 is disposed on the lower side surface of the container body 7 as a diffusion means for diffusing active oxygen species and ion species in water. The ultrasonic oscillator 12 is provided with ultrasonic vibration provided in the container 6. It is connected to the child 22 (2.4 MHz atomizing ultrasonic transducer). Note that although an ultrasonic transducer that generates high-frequency ultrasonic waves (generally said to be 500 kHz or higher) is used here, medium-frequency ultrasonic waves (100 kHz to 500 kHz) may be used.

  It is estimated that these ultrasonic waves may promote the release of active oxygen species from the photocatalyst 20 and may enhance the reaction with each other by the mutual interference action of the ultrasonic wave and the ultraviolet wavelength.

  In the first embodiment, ultrasonic waves are used as the diffusing means, and the photocatalyst 20 is indirectly oscillated through the water 31 to diffuse active oxygen species and ion species. However, the present invention is not limited to this. For example, the photocatalyst 20 may be moved directly in the container 6, and a fan (stirring blade) that stirs the water 31 in the container 6 to generate a water flow is additionally provided. Then, active oxygen species or ion species may be diffused.

  The lid 8 has an ultraviolet lamp 9 (EFD15BLB manufactured by Toshiba Lighting & Technology Corp., peak wavelength 352 nm, UV output 1.8 W) as a light source for irradiating light inside the container 6 so as to penetrate the lid 8. By energizing the ultraviolet lamp 9, it is possible to irradiate the photocatalyst body 20 (described later) provided inside the container 6 with ultraviolet rays. Further, since the energization part of the ultraviolet lamp 9 is in the air, there is no risk of an accident such as leakage even if the light emitting part is submerged in water. However, for the purpose of improving safety, the light emitting part may be disposed so as to be surrounded by cylindrical quartz glass. In addition, the surface of the fiber is subjected to prism processing, the light source is scattered light, and the fibrous photocatalyst is irradiated with ultraviolet rays from various angles so as to minimize the number of portions that are not irradiated with ultraviolet rays. Also good.

  The ultraviolet lamp 9 can be a black light or the like, but may be an ultraviolet lamp 9 that effectively emits ultraviolet light having a wavelength of 350 to 370 nm, more preferably ultraviolet light having a wavelength of 364 nm. There is no limitation, and an LED or a xenon lamp capable of emitting ultraviolet rays can be used. When the light source is sunlight, it is possible to irradiate the photocatalyst 20 with a large amount of ultraviolet light contained in sunlight, and the light is guided to the water using an optical fiber or a prism to irradiate the photocatalyst 20. It is also possible to do. In addition, if the photocatalyst 20 is a rutile type (visible light responsive type) photocatalyst, a photocatalytic reaction can be induced even by ordinary visible light (indoor lighting), so that light can be transmitted underwater using an optical fiber or a prism. It is also possible to irradiate the photocatalyst body 20.

  Next, the cover 8 of the container 6 is removed, and the inside viewed from the upper opening of the container body 7 is shown in FIG. 3, and the cross section of the functional water generator 1 is shown in FIG.

  An ultrasonic transducer 22 connected to the ultrasonic oscillator 12 is disposed at the bottom of the inner surface side of the container body 7 so as to come into contact with water. The photocatalyst body 20 is disposed. As shown in FIG. 4, the photocatalyst body 20 is disposed so as to surround the light emitting portion 41 of the ultraviolet lamp 9 when the container body 7 is closed with the lid body 8. Therefore, the ultraviolet rays emitted from the ultraviolet lamp 9 can be efficiently used as energy for exciting the photocatalyst 20.

  By the way, the ultraviolet rays irradiated from the ultraviolet lamp 9 and passed through the photocatalyst body 20 strike the container body 7 and the lid body 8.

  Here, the outer peripheral surfaces of the container body 7 and the lid body 8 are covered with a reflecting material 13 that can reflect light such as ultraviolet rays.

  Therefore, the ultraviolet rays that have reached the container body 7 and the lid body 8 are reflected by the reflecting material 13 toward the inside of the container body 7 (that is, in the direction of the photocatalyst body 20) to excite the photocatalyst body 20, and the ultraviolet lamp 9 More irradiated ultraviolet rays can be used as the activation energy of the photocatalyst 20 without waste.

  The reflector 13 is preferably made of a material that can reflect light, particularly a material that can reflect ultraviolet rays, and for example, an aluminum foil can be used.

  In this embodiment, the reflecting material 13 is attached to the outer peripheral surface of the container main body 7 and the lid body 8. However, the reflecting material 13 may be attached to the inner peripheral surface. You may comprise with the raw material which has the function similar to 13. In particular, when the container 6 is made of plastic or resin, the amount of ultraviolet rays received by the container 6 can be reduced by providing the reflecting material 13 on the inner wall of the container 6, and the deterioration or modification of the plastic or resin due to ultraviolet rays can be reduced. Can be prevented.

  Further, the photocatalyst body 20 is formed by coating substantially the entire surface of the alumina metal fiber body with a titania thin film so that the titania thin film can be excited by receiving ultraviolet rays emitted from the ultraviolet lamp 9. Yes.

  In Example 1, the carrier of the photocatalyst (titania) is a metal fiber body, but is not limited thereto, and can be a porous body composed of organic and / or inorganic materials. For example, the photocatalyst body 20 may be formed by forming a titania thin film on the surface of a glass fiber body, a ceramic fiber body, or a nonwoven fabric. Here, the porous body is a concept including a wool-like body that is an assembly of fiber bodies.

  Next, the flow until the water supplied from the water supply port 2 is taken out as functional water from the drain port 11 including the active oxygen species and ionic species will be described below.

  That is, the water 31 supplied from the water supply port 2 flows through the water supply pipe 3 and reaches the precursor supply unit 5. A precursor supply pipe 4 is connected to the precursor supply section 5, and the water 31 that has reached the precursor supply section 5 and the precursor fed by the precursor supply pipe 4 are mixed.

  The precursor mixed with the water 31 in this manner is dissolved in the water 31 and sent into the container 6 as an aqueous solution while increasing the concentration of the precursor in the water.

  The aqueous solution that has reached the inside of the container 6 is further promoted by ultrasonic vibration to further increase the concentration of the precursor in the water 31 or make it uniform.

  Further, when the precursor is a gas, the remaining minute bubbles collide with the photocatalyst body 20 and are repelled to generate high-frequency ultrasonic waves. This ultrasonic wave helps to vibrate the photocatalyst body 20 directly or indirectly and promote the liberation of active oxygen species and ion species.

  The water 31 having the increased precursor concentration reaches the inside of the container 6 and fills the container 6.

  On the other hand, ultraviolet light having a wavelength of 350 to 370 nm is emitted from the energized ultraviolet lamp 9, and the emitted ultraviolet light strikes the photocatalyst body 20 surrounding the ultraviolet lamp 9.

  Since the titania thin film having photocatalytic activity is formed on the surface of the photocatalyst body 20, the titania thin film is excited by the ultraviolet light emitted from the ultraviolet lamp 9 being applied to the titania thin film, and the photocatalyst body 20 is activated. It will be.

On the surface of the activated photocatalyst 20, the ultraviolet energy (hν) emitted from the ultraviolet lamp 9 excites the titanium oxide (TiO ₂ ) constituting the titania thin film, so that the water 31 filling the container 6 can be obtained. When the (aqueous solution) comes into contact with the excited photocatalyst 20, the active oxygen species is liberated into the aqueous solution.

  Then, the reactive oxygen species liberated from the photocatalyst 20 react with the solute in the aqueous solution to generate ionic species.

In addition, when a substance that increases dissolved oxygen in water (for example, molecular oxygen) is used as a precursor, oxygen is mixed in the water 31 filling the container 6 in the precursor supply unit 5 and dissolved oxygen. Since the concentration is high, the efficiency of contact between the electrons (e ⁻ ) generated on the photocatalyst 20 and oxygen contained in the water 31 can be improved.

  Therefore, when the water 31 containing a large amount of oxygen comes into contact with the activated photocatalyst 20, the photocatalytic reaction actively occurs and more active oxygen species are generated on the surface of the photocatalyst 20.

  Thereby, the production amount of ionic species can be further increased.

  In addition, fine bubbles generated when oxygen is mixed in are ruptured by colliding with the metal fiber body, generate ultrasonic waves, vibrate the metal fiber body, and active oxygen species generated on the metal fiber body are metal. Easier to release than fiber.

  On the other hand, the energized ultrasonic oscillator 12 vibrates the ultrasonic vibrator 22 disposed inside the sealed container 6 to generate ultrasonic waves.

  Here, the generated ultrasonic waves vibrate the water 31 and the photocatalyst body 20, and in particular, the photocatalyst body 20 provided in the functional water generator 1 according to the present invention has a photocatalyst on the surface of the metal fiber. (For example, titania) is coated to form a metal fiber body as a wool-like aggregate.

  Therefore, active oxygen species are generated from the surface of the metal fiber body having a large surface area in which the surface area of each metal fiber is gathered, and at the same time, the generated active oxygen species are promptly transmitted by ultrasonic waves. It is shaken off from the surface of the photocatalyst 20 by vibration and released in a large amount in the water 31.

  Then, new active oxygen species are immediately generated on the surface of the photocatalyst 20, and are again shaken in accordance with the vibration of the ultrasonic wave and are released into the water 31.

  Since this is repeated many times in an instant, the active oxygen species can be contained in the water 31 very efficiently.

  Further, the photocatalyst body 20 is likely to vibrate in accordance with the fine vibration of the ultrasonic wave, for example, compared with a plate-like photocatalyst, and the active oxygen species can be more easily released from the surface of the photocatalyst body 20.

  Furthermore, since the end portion of the metal fiber present in a large amount in the photocatalyst 20 behaves as a free end under ultrasonic vibration, the active oxygen species can be efficiently shaken off from the photocatalyst 20.

  Moreover, since the photocatalyst 20 is made of an alumina fiber that can be satisfactorily coated with titania as its carrier, titania is relatively firmly bonded on the surface of the alumina and has high durability. Can withstand long-term use while maintaining practicality. This is particularly practical when used in seawater where metals are easily corroded.

  Thus, due to the synergistic effect of the photocatalyst 20 and the ultrasonic wave, the active oxygen species generated on the surface of the photocatalyst 20 are easily released into water, and these active oxygen species and solutes react further. As a result, a large amount of ionic species is contained in the water, and functional water is generated.

  And since the functional water produced | generated inside the container 6 by the water 31 continuously supplied from the water supply port 2 will be extruded from the drain port 11 provided in the container 6 upper side surface, functional water is contained in the container 6 inside. Can be taken out from.

  The ionic species contained in the functional water thus generated has very high reactivity and durability, and can be used in various fields such as sterilization, sterilization, anthelmintic, washing, and drinking. .

  In particular, when a precursor capable of generating an ionic species having a strong oxidative decomposition ability is supplied from the precursor supply pipe 4, the generated functional water quickly has a fatal effect on microorganisms, parasites, and the like. It becomes possible to give to.

  Next, the case where the functional water production | generation system for disinfection is comprised using the functional water production | generation apparatus 1 demonstrated in Example 1 is demonstrated.

  That is, as shown in FIG. 5, a sterilizer 23 having a sterilizing lamp 24 is provided between the water supply pump 32 immersed in the water 31 in the water tank 33 and the functional water generator 1. It is possible to irradiate the water 31 circulated inside the sterilizer 23 with the ultraviolet rays radiated from 24.

  The germicidal lamp 24 provided in the sterilizer 23 can emit ultraviolet rays having a wavelength of 245 to 265 nm, more preferably 256 nm, and can sterilize microorganisms by damaging the DNA of microorganisms in water due to mutational damage. .

  Moreover, the mirror surface given to the wall surface of the functional water production | generation apparatus 1 and the light-shielded piping also have the effect of preventing light recovery. By preventing photorecovery, damage to microorganisms due to ultraviolet rays having a wavelength of 245 to 265 nm can be efficiently given, and the bactericidal effect can be improved.

  In this functional water generator 1, active oxygen species and ionic species diffuse into the water, so that the microorganisms that have not been sterilized by the sterilizer 23, are damaged by the cell membrane, are weakened, and reach the functional water generator 1. In this case, the active oxygen species and ionic species cause further fatal damage and sterilization.

  The sterilizer 23 is disposed in the functional water generator 1 via the connecting pipe 26, but is not limited thereto, and excites the photocatalyst 20 disposed in the functional water generator 1. A germicidal lamp 24 that generates ultraviolet light with a wavelength of 245 to 265 nm is installed inside the functional water generator 1 together with a light source (for example, an ultraviolet lamp 9 that generates ultraviolet light with a wavelength of 350 to 370 nm) The functional water generator 1 and the sterilizer 23 may be configured integrally, and a light source that simultaneously emits light that can excite the photocatalyst 20 and light that can be sterilized is provided in the functional water generator 1. You may make it install.

Next, an example in which a functional water generating system for anthelmintic insects is constructed using the functional water generating device according to the present invention will be described. This functional water generating system for anthelmintic exhibits an excellent anthelmintic ability against parasites parasitic on fish and the like. Hereinafter, the result of having verified about the configuration example of the functional water generation system for anthelmintic and the anthelmintic effect of the functional water generated by the functional water generating system for the anthelmintic is shown.
[Configuration example of an anthelmintic functional water generation system]
The functional water generating system for anthelmintic and the anthelmintic method will be described with reference to FIGS.

  In FIG. 6, the functional water generator 101 is disposed in the water tank 133, and the seawater 142 in the water tank 133 is circulated to the functional water generator 101 so that the seawater 142 includes active oxygen species and ion species. Indicates the state.

  Here, a water supply pump 132 is installed at the tip of the water supply port 102, and by operating the water supply pump 132 and supplying water to the functional water generator 101 at a flow rate of 6.2 L / min, through the water supply pipe 103, Seawater in which oxygen is dissolved can be supplied to the functional water generator 101.

  Then, since the photocatalyst 120 is excited by the ultraviolet light irradiated from the ultraviolet lamp 109 and the ultrasonic wave is emitted from the ultrasonic vibrator 122 to the seawater supplied to the functional water generator 101, the photocatalyst 120 is used. As a result, a large amount of active oxygen species are released from the water, and active oxygen species and ionic species are efficiently dissolved in seawater.

  Seawater containing a large amount of ion species, that is, seawater that has become functional water passes through the drain pipe 110, is discharged from the drain port 111, and flows into the water tank 133 again.

  Since the fish tank 145 is stored in the aquarium 133 in advance, the water containing ionic species discharged from the functional water generator 101 affects microorganisms, parasites, and the like attached to the fish 145. Can be used to deter parasites. Here, the fish 145 indicates a concept including not only adult fish but also fry and young fish.

  In FIG. 6, one functional water generator 101 is disposed in one aquarium 133, but as shown in FIG. 7, the number of fish 145 to be defeated and the amount of seawater stored in the aquarium 133. Alternatively, the number of functional water generating devices 101 may be increased according to the desired functional water ion species concentration.

In FIG. 7, the functional water generator 101 is arranged in parallel in the water tank 133, but as shown in FIG. 8, the functional water generator 101 is connected in series using a connecting pipe 126 or the like. It may be arranged. In this case, the functional water discharged from the drain 111 through the two functional water generators 101 contains a larger amount of ionic species than the functional water discharged from the single functional water generator 101. Therefore, when water containing a high concentration of ionic species is desired, it can be suitably used.
[Example 1 of functional water generation system for anthelmintic insects]
Next, FIG. 9 shows an example in which parasites and microorganisms attached to the fish are removed by bringing the functional water generated through the functional water generator 101 and the sterilizer 123 into contact with the fish.

  10 liters of seawater 142 was stored in the aquarium 133, and a sterilizer 123 and a functional water generator 101 were disposed on the upper part of the aquarium 133 to construct a functional water generating system for anthelmintic insects.

  Here, a water supply pump 132 is installed at the tip of the water supply port 102, and by operating the water supply pump 132 and supplying water to the functional water generator 101 at a flow rate of 6.2 L / min, through the water supply pipe 103, Seawater in which oxygen is dissolved can be supplied to the functional water generator 101.

  The functional water generator 101 was operated in advance for 1 hour, and the seawater temperature was 28 ° C. and the dissolved oxygen concentration (DO) was adjusted to 6.8 mg / L. The seawater temperature and dissolved oxygen concentration were tested while keeping them constant thereafter. The concentration of hydrogen peroxide in circulating functional water was always 3 ppm or less.

  And as shown in Table 1, the fish 145 used as a test object was swam.

表１に示すように、水槽にはカンパチ４匹とトラフグ４匹を収納した。また、これらの魚145のエラを事前に調査した結果、魚１匹あたりの平均エラムシ数は、カンパチ20匹とトラフグ30匹であった。

As shown in Table 1, the aquarium accommodated 4 amberjacks and 4 trough puffers. Moreover, as a result of investigating the era of these 145 fishes in advance, the average number of aphids per fish was 20 amberjacks and 30 trough puffers.

  And after operating and circulating the functional water production | generation apparatus 101 of both tanks for 2 hours, the same apparatus was stopped, two amberjacks and two trough puffers were taken out, and the state of the aphid of the fish 145 was observed. The remaining two amberjacks and two tiger puffers were returned to the sea sacrifice and 20 hours later, the state of the aphid fish 145 was confirmed. The results are shown in Table 2.

表２に示すように、２時間に亘って機能水生成装置101を稼働させた、カンパチ２匹とトラフグ２匹の魚145に付着していたエラムシの数は、終了直後は平均でカンパチ17匹とトラフグ15匹であり、寄生したエラムシの数は約半数になり、しかも寄生したエラムシの活動性は低下していた。

As shown in Table 2, the average number of aphids attached to the fish 145 of 2 amberjacks and 2 trough puffers that operated the functional water generating apparatus 101 for 2 hours was an average of 17 amberjack immediately after the end. The number of parasitic aphids was about half, and the activity of parasitic aphids had declined.

  After 20 hours of operation, the number of aphids adhering to the remaining two amberjacks and two tiger puffer fish 45 was significantly reduced to an average of 0 campips and 2.5 pufferfish on average.

From these results, since the functional water generated by the functional water generator 101 contains many ionic species, the seawater is first purified, and then the purified water is added to the fish 145. It was thought that it worked extremely effectively against the aphid and dewormed the aphid.
[Example of usage of functional water generation system for anthelmintic insects 2]
Next, an example in which parasites and microorganisms attached to the fish are removed by bringing the functional water generated through the functional water generator 101 and the sterilizer 123 into contact with the fish will be described with reference to FIG. .

  30 liters of seawater 142 was stored in the aquarium 133, and a sterilizer 123 and a functional water generator 101 were disposed on the upper part of the aquarium 133 to constitute a functional water generating system for anthelmintic insects.

  Two water tanks 133 equipped with such a functional water generating device 101 are prepared, and each functional water generating device 101 is operated for one hour, and the seawater temperature is 28 ° C. and the dissolved oxygen concentration (DO) is 6.8 mg. Adjusted to / L. The seawater temperature and dissolved oxygen concentration were tested while keeping them constant. Moreover, the concentration of hydrogen peroxide in circulating functional water was always 3 ppm or less, as in Example 1 of the usage state of the functional water generating system for anthelmintices.

  And as shown in Table 3, the fish 145 used as a test object was swam. Here, of the two water tanks 133, one water tank 133 will be described as water tank A, and the other water tank 133 will be described as water tank B.

表３に示すように、水槽Ａにはカンパチ６匹とトラフグ１匹を収納し、水槽Ｂには、カンパチ５匹を収納した。また、これらの魚145のエラを事前に調査した結果、魚１匹あたりの平均エラムシ数は、両水槽とも20匹であった。

As shown in Table 3, 6 amberjacks and 1 trough puffer were stored in the water tank A, and 5 amberjacks were stored in the water tank B. Moreover, as a result of investigating these 145 fish in advance, the average number of aphids per fish was 20 in both tanks.

  And the functional water production | generation apparatus 101 of both water tanks was operated, and the test was started. Here, after the functional water generating apparatus 101 was operated for 4 hours for the water tank A and for 6 hours for the water tank B, the apparatus was stopped, and the state of the aphid of the fish 145 after 20 hours was confirmed. The results are shown in Table 4.

表４に示すように、４時間に亘って機能水生成装置101を稼働させ、20時間経過した水槽Ａ内の魚145に付着していたエラムシの数は、平均で３匹であった。

As shown in Table 4, the functional water generator 101 was operated for 4 hours, and the number of aphids adhering to the fish 145 in the tank A after 20 hours was 3 on average.

  In addition, the functional water generator 101 was operated for 6 hours, and the number of aphids attached to the fish 145 in the tank B after 20 hours was 1 on average.

  From these results, it is suggested that the functional water generated by the functional water generating apparatus 101 works extremely effectively against the aphids parasitized on the fish 145 and can deworm the aphids.

  Furthermore, the point that should be particularly noted in this result is that there is no dead fish in spite of the fact that the fish 145 has been weakened by the aphid infestation. This means that the functional water generated by the functional water generator 101 has a strong anthelmintic effect on the aphids, but acts very gently on the fish 145 and has almost no adverse effects. This was thought to suggest.

  Moreover, since the anthelmintic effect of the functional water on the parasite is based on the ionic species, the parasite and the microorganism do not have a risk of acquiring resistance and can be used for a long time.

  In addition, functional water used for the control of parasites and microorganisms can be quickly changed to substances such as water and oxygen even if released into nature, so there is no risk of adverse effects on the environment.

  As described above, the treatment may be performed by mixing the functional water into the water in which the fish 145 lives, but the same effect can be obtained by immersing the fish 145 in the functional water stored in advance for a predetermined time. be able to.

  In addition, in order to interfere with the invasion of powerful ionic species, sustained release calcium carbonate, calcined New Century uplifts, etc. can be placed in the circuit.

  At the same time, functional water is generated from the water supply pump 132 in order to prevent contaminants floating in the water and parasites such as aphids that have fallen from the fish from adhering to the photocatalyst 120 and reducing the generation efficiency of ionic species. A filter may be provided in the flow path of the water supplied to the apparatus 101.

  In the present embodiment, the case where the fish 145 is a cultured fish has been described, but it goes without saying that the present invention can be applied even when the fish 145 is an ornamental fish. In particular, when the functional water generator 101 is applied to ornamental fish bred in ordinary households, water containing active oxygen species is regularly supplied into the aquarium 133 or excessive functional water is supplied. In order to prevent this, a timer or a limiter for controlling energization of the ultraviolet lamp 109 may be provided. By setting it as such a structure, the health state of an ornamental fish can always be kept favorable.

Moreover, when the energization of the ultraviolet lamp 109 is interrupted, oxygen-rich water is supplied from the drain 111 into the aquarium 133, so that the growth environment of the fish 145 is kept good. be able to.
[Example 3 of usage of functional water generation system for anthelmintic insects]
Next, an example in which parasites and microorganisms attached to the fish are removed by contacting the fish with the functional water generated by installing two functional water generators 101 in series will be described with reference to FIG. To do.

  50 liters of seawater 142 was stored in the water tank 133, and two functional water generators 101 were arranged in series above the water tank 133 to constitute a functional water generating system for anthelmintic insects.

  Here, a water supply pump 132 is installed at the tip of the water supply port 102, and by operating the water supply pump 132 and supplying water to the functional water generator 101 at a flow rate of 6.2 L / min, through the water supply pipe 103, Seawater in which oxygen is dissolved can be supplied to the functional water generator 101.

  This functional water generator 101 was operated in advance for 40 minutes to adjust the seawater temperature to 25 ° C. and the dissolved oxygen concentration (DO) to 7.0 mg / L. The seawater temperature and dissolved oxygen concentration were tested while keeping them constant.

  In the aquarium, 5 oysters that had been confirmed to have infested with aphids were placed in the cage before being put into the aquarium. After operating this functional water generator 101 for 30 minutes, the number of aphids attached to the gills of these fish was an average of three. However, all of the aphids stopped their activity and became white, and were judged to have lost their activity and were killed by severe cell damage.

  Therefore, we observed the reaction that occurred in a completely unrelated place by dripping the functional water taken out of the water tank with a dropper while observing the aphid alone, which was infested with the spider, with a microscope.

    The aphid that has parasitized the moth causes whitening of the attached surface immediately after the functional water is dripped, and the entire attached surface turns white after 30 seconds. The leucoplasty was curled throughout the whole and for about 15 minutes. After moving while shaking the body like a convulsion, the activity was stopped while contracting and curling. This change was also observed in 5 drenched aphids, and it was judged that functional water can deworm the aphids in about 15 minutes.

    Some aphids are separated from sputum when they are dripped with functional water, and try to escape from the spot, so that a high degree of cell damage can occur without requiring high hydrogen peroxide concentration. It was.

  Next, an example of measuring the active oxygen concentration of functional water generated by installing the functional water generator 1 will be described with reference to FIG.

  4 liters of water 31 was stored in the water tank 33, and the functional water generating system 1 was configured by arranging the functional water generating device 1 in the upper part of the water tank 33.

  Here, a water supply pump 32 is installed at the tip of the water supply port, and the water supply pump 32 is operated to supply water to the functional water generator 1 at a flow rate of 6.2 L / min.

    Experiments on the measurement of active oxygen species were conducted using pure water for ion chromatography, tap water, river water, and artificial seawater as types of water to be placed in the water tank.

The measurement method superoxide anion radicals (O ₂ ^-), hydrogen peroxide (H ₂ O _2), hydroxyl radical ^(· OH), singlet oxygen ⁽¹ O _2), halogenation oxygen (ClO ^-), monoxide to the nitrogen radical (NO ^·), respectively, color development, fluorescence antibody technique, ESR (electron spin resonance) method to confirm the occurrence using the spin trap method.

  Thereby, the optimum gas concentration and the optimum ultrasonic frequency were determined.

  Next, an example of observing the influence of functional water generated by installing the functional water generator 1 on protozoa will be described with reference to FIG.

  4 liters of water 31 was stored in the water tank 33, and the functional water generating system 1 was configured by arranging the functional water generating device 1 in the upper part of the water tank 33.

  Here, a water supply pump 32 is installed at the tip of the water supply port, and the water supply pump 32 is operated to supply water to the functional water generator 1 at a flow rate of 6.2 L / min.

    Experiments on the effects on protozoa were conducted using pure water for ion chromatography, tap water, river water, and 10-fold diluted artificial seawater.

  Three types of protozoa, Paramecium caudatum, Paramecium aurelia complex, and Paramecium aurelia complex (P. bursaria), in a water tank that had been circulated for 1 hour in advance and into a casing that was dispensed every 100 cells. Immediately after stopping the device, the protozoan was measured by counting the number of cells surviving in the casing after 12 hours after being added over time, 5 minutes, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour later The effect on the kind was judged.

  As a result, the optimum gas concentration and the optimum ultrasonic frequency were determined and the reaction duration was measured, and the effects of trace residual substances on the environment and ecosystem were measured.

As mentioned in Example 2, the functional water generator according to the present invention exhibits excellent sterilization and sterilization ability against microorganisms. Moreover, as shown in the functional water generating system for anthelmintic insects of Example 3, it has been confirmed that the effect of functional water is manifest not only in the reaction local area but also in a distant place moved in both time and space. . An application example of a functional water generator that applies such excellent sterilization, sterilization, and anthelmintic ability to daily necessities is shown below.

(I) Example used for sterilizer in circulating water First, an example of treating microorganisms of circulating water in a bathtub that circulates hot water or an outdoor unit of a cooling device is shown. By disposing this functional water generator 1 in the circulating water treatment circuit, it is possible to sterilize Legionella bacteria, which has been a problem in recent years.

  In other words, Legionella is a Gram-negative bacilli that exists in the environment, such as in water or in moist soil, and has an optimum temperature of 15 to 43 ° C. Cooling of bathtubs, air conditioners, freezers, refrigerators, etc. that circulate hot water It grows in large quantities in the cells of protozoa (amoeba) that live in water such as outdoor units attached to equipment.

  Moreover, Legionella grows in large quantities in the protozoan (amoebae) cells, and directly inhales water vapor containing a large amount of living cells released from the body when the protozoa die after passage of generation. This is known to infect humans. That is, as a countermeasure against sterilization of Legionella, not only sterilization of Legionella itself, but also a process that realizes both destruction of the cell membrane of protozoa and sterilization of Legionella that is proliferating in it is important. Simply bactericidal power of Legionella is insufficient.

  At this time, not only normal sterilization but also protozoan parasitised with bacteria is required, and a stronger oxidizing power is required.

  However, according to the functional water generated by the functional water generating apparatus shown in the present embodiment, as shown in Example 3, it is possible to deter parasites parasitic on fish, and protozoa that are weaker than parasites are It can be disinfected.

  That is, since the protozoa can be killed and the Legionella bacteria that live in the protozoa can be sterilized, infectious diseases caused by Legionella bacteria can be prevented.

  In this case, it is recommended to use a sterilizing lamp in combination in order to maintain a wider sterilizing effect and a strong sterilizing power.

(Ii) Example of processing ballast water of ship Next, an example of processing of harmful organic substances and microorganisms contained in ballast water for adjusting the center of gravity and buoyancy of the ship will be shown. For example, by disposing the functional water generating device according to the present invention in a ballast tank of a ship or in a ballast water drain, safe and effective ballast water can be obtained without adding additional chemicals. Can be processed.

  Ships take seawater into the ballast tank and adjust the center of gravity and buoyancy. In many cases, the water taken into the ballast tank (ballast water) must be discharged on a different ocean from where it was taken in. It becomes.

  For example, in a large vessel that sails in the open ocean, when the load is low, the ballast water is taken into the ballast tank to increase the weight of the hull to ensure the stability of the hull, and arrive at a destination such as a foreign country to load the load. At that time, the ballast water is drained to lighten the hull, and the weight of the hull is adjusted.

  However, there are many microorganisms and organic substances in seawater, and there is concern about the danger of destroying the ecosystem and environment of the drainage site when these are drained as ballast water in other remote areas. Yes.

  In particular, marine organisms carried in this way may be abnormally proliferated by destroying the food chain in the drainage area, which may cause a great deal of damage to the aquaculture industry.

  Therefore, by disposing the functional water generating device according to the present invention in the ballast tank of the ship and circulating the ballast water in the functional water generating device, microorganisms and the like contained in the ballast water can be killed, and the ballast water Can decompose harmful organic substances contained in

  In addition, when ballast water is circulated through the functional water generator to obtain functional water, shellfish, seaweeds, and the like can be prevented from adhering to the ballast tank.

  In addition, in this example, as an example of ballast water treatment means, it is installed in a ship's ballast tank or drain outlet, but it is not particularly limited to this, and it is installed in a port where the ship is anchored. Alternatively, the ballast water may be collected by a pump or the like, treated with a functional water generator, and then discharged to the ocean.

  In this way, by treating ballast water with a functional water generator, it is possible to prevent the destruction of ecosystems and environmental pollution due to harmful organic substances, and more environmentally compared to the treatment of ballast water with chemicals. The ballast water after treatment can be drained into the ocean while suppressing adverse effects on the sea.

(Iii) Denture Cleaning Example Next, an example in which the denture 34 mounted in the oral cavity is sterilized with functional water reaction water will be described with reference to FIG. By disposing the functional water generating device 1 according to the present invention in the water tank 33 having a predetermined capacity and immersing the dentures 34 in the water tank 33, an excellent cleaning effect and removal can be achieved without adding a separate drug or the like. Bactericidal and bactericidal effects can be obtained.

  That is, the dentures 34 to be installed in the oral cavity are liable to deposit food traps, cigarette spears, etc., and need to be washed frequently. However, the deposited dirt is difficult to remove, and a great deal of effort has been expended, such as brushing and polishing for a long time.

  In addition, because the dentures 34 are installed in the oral cavity, cleaning agents and disinfectants that are harmful to the human body cannot be used, and processing was performed exclusively using commercially available disinfecting cleaners, but the deposited dirt is removed. It was hard to say an effective means.

  Therefore, for example, as shown in FIG. 10, the functional water generating device according to the present invention is configured integrally with the denture cleaning device 35 and immersed in the water 31 of the water tank 33 to operate the functional water generating device 1. Thus, the dentures 34 can be effectively cleaned. In FIG. 10, as a means for increasing the dissolved oxygen concentration in water, oxygen generator 63 is immersed in water, and this oxygen generator 63 comes into contact with water to generate bubbles, which are contained in the bubbles. Oxygen is dissolved in the water.

  Then, the water tank 33 having a predetermined capacity is divided into two parts, the functional water generating device 1 according to the present invention is arranged in one water tank, and the denture is immersed in the other water tank 33 (cleaning tank), thereby separately. An excellent cleaning effect and sterilization / bactericidal effect can be obtained without adding a drug or the like. By providing an underwater fan 61 between the two water tanks to enable water convection, the functional water can clean the dentures 34 in the cleaning tank.

  In particular, water containing active oxygen species rich in reactive oxygen species and hydrogen peroxide comes into contact with the dentures 34, so that food traps and cigarette crabs deposited on the dentures 34 are strongly oxidized, and the dentures 34 It becomes easy to remove the dirt from.

  In addition, functional water has a strong sterilizing and bactericidal effect, so it can prevent bacteria and fungi that grow in the oral cavity of the oral cavity attached to the dentures 34 and the food traps attached to the dentures 34. The dentures 34 can be sanitized and sanitized.

  In addition, since the water tank 33 is divided into two parts, it is possible to install the low frequency ultrasonic transducer 22 in the cleaning tank without damaging the photocatalyst in the photocatalytic reaction tank. It can be used to float dirt, and the oxidative decomposition reaction by active oxygen species can be promoted.

In addition, reactive oxygen species and hydrogen peroxide contained in functional water are quickly converted into innocuous substances such as water (H ₂ O) and oxygen (O ₂ ) by touching and reacting with organic substances. It is possible to attach the dentures 34 without an adverse effect on the teeth.

  By using this denture cleaning system, the medical instrument 62 can be cleaned.

(Iv) Example used for cleaning dishes Next, an example in which functional water is brought into contact with dishes and sterilized and cleaned will be described. For example, the functional water generating apparatus 1 according to the present invention is disposed between water supply hoses of a dishwasher, or the functional water generated by the functional water generating apparatus 1 by being configured integrally with the dishwasher is jetted onto the dishes. By doing so, tableware can be washed safely, effectively and hygienically without adding a separate drug or the like.

  In other words, foods are attached to the dishes (dish, chopsticks, knives, and forks) used during meals, especially oils derived from fish and meat and starchy stains derived from cereals. Yes. Such dirt is unsanitary because it tends to be a place for microbial growth and comes in contact with food the next time these dishes are used.

  Therefore, it is necessary to wash dishes after eating using tap water together with dishwashing detergent. However, dishwashing is one of the hard work in housework.

  You can also use a dishwasher that sprays tap water on dishes, but oil stains can be effectively removed with dishwashing detergents, but starchy stains are difficult to remove. Met.

  Therefore, by using the functional water generated by the functional water generator 1 according to the present invention as the water sprayed from the dishwasher, the powerful oxidation of the photocatalytic water has not only oil stains but also starch stains. It can be oxidized and removed effectively by force, and the tableware can be sterilized to a sanitary state.

  Moreover, even when eating fermented foods, such as fermented foods using spore-like microorganisms such as natto, at the time of eating, as can be seen from the verification results of the sterilization effect of functional water shown above, It can be sterilized sufficiently.

  In addition, in this example, as an example of the function water being brought into contact with the tableware, an example in which the function water is sprayed by a dishwasher is shown. You may make it store water and immerse tableware in this stored photocatalytic reaction water.

  In this way, by washing the dishes with functional water, even when the functional water adheres to the dishes, it is safe for the human body, and when the dishes are washed, the dishes are sufficiently hygienic. can do.

(V) Example used for washing food Next, an example in which functional water is brought into contact with food to perform sterilization washing and removal of protozoa attached to processed food will be described. For example, the functional water generating apparatus 1 according to the present invention is disposed on a food processing cooking table and the like, and is used for washing vegetables and fruits or for washing seafood. Hygienic vegetables and fruits and processed fish products can be obtained.

  That is, since vegetables and fruits are mainly grown and harvested outdoors, there are cases where dirt, microorganisms, insects, and the like are attached. For example, leafy vegetables such as cabbage are cultivated at a relatively low position from the ground, so that mud and the like are easily attached to them, and eggs such as moths and butterflies are laid, and larvae also breed.

  Therefore, it is necessary to wash vegetables and fruits before they are used for food, but simply rinsing them with water is not effective because they are poor in sterilizing ability and washing ability.

  It is also possible to wash vegetables and fruits with food-grade detergents, but there is a possibility that components such as surfactants contained in the detergent may remain in the washed vegetables and fruits. It ’s something that consumers want to avoid.

  Furthermore, when producing fresh fish processed foods, it is very important to conduct inspection work to remove protozoan parasites such as anisakis that have parasitized the internal organs of seafood. However, functional water treated with a functional water generator that can control protozoa is pre-soaked and washed to prevent deterioration of freshness due to freezing and safe processing of fresh fish. It becomes possible to provide food at low cost.

  Therefore, the functional water generating apparatus 1 according to the present invention is configured integrally with a cooking table or the like, and the generated functional water is used for washing vegetables and fruits, so that attached dirt can be effectively removed. Moreover, it can kill insects and microorganisms.

  In addition, since vegetables and fruits are often sprayed with agricultural chemicals during cultivation, reactive oxygen species contained in the functional water, etc., can be obtained by washing the vegetables and fruits with this functional water. It is possible to reduce the adverse effects on the human body.

  Moreover, the functional water contains a large amount of so-called negative ions, and can maintain the freshness of the appearance without causing defoliation of leafy vegetables and the like.

  As a means of bringing functional water into contact with vegetables and fruits, the functional water may be stored in an appropriate amount of container and immersed in the stored functional water. It may be applied to the fruit.

  Thus, by washing vegetables and fruits with functional water, the vegetables and fruits can be sterilized and washed hygienically and safely without damaging the freshness of the vegetables and fruits.

(Vi) Example Used for Cleaning Precision Equipment Next, an example in which the functional water generating apparatus 1 according to the present invention is used for cleaning precision equipment will be described. For example, the functional water generating apparatus 1 according to the present invention is disposed between water supply hoses of a silicon wafer cleaning machine for manufacturing a semiconductor, or is configured integrally with a silicon wafer cleaning machine so that the functional water generating apparatus 1 By making the generated functional water touch the silicon wafer, it is possible to clean the silicon wafer safely and effectively without adding a separate chemical or the like.

  That is, in the process of manufacturing semiconductors used in electronic devices, fine dust may be generated on the silicon wafer as unnecessary parts are removed. Since this dust causes defective products in semiconductor manufacturing, it must be removed using organic compounds such as organic solvents and chelating agents. The organic compounds used to remove this dust also adhere to the silicon wafer. Will need to be removed.

  In order to remove these organic compounds, hydrogen peroxide water is used. However, in addition to the danger of handling, treatment is required to discard the hydrogen peroxide water after use.

  Then, the organic compound adhering to a silicon wafer is removable by using the functional water produced | generated with the functional water production | generation apparatus which concerns on this invention as a substitute of hydrogen peroxide water.

  In addition, functional water is less affected even when it comes into contact with the human body than hydrogen peroxide water, and is highly safe, so that it can be handled easily and work efficiency can be improved.

  Furthermore, although the oxidizing power of active oxygen species contained in functional water is high, it is extremely unstable and its reaction time is short, so even in continuous semiconductor manufacturing, cleaning can be performed without hindering the manufacturing process in time. Is possible.

  In this example, the object to be cleaned is a silicon wafer. However, the present invention is not limited to this, and it can be used for cleaning various precision instruments such as printed boards and electronic parts.

(Vii) Example applied to a toilet water storage tank Next, an example in which the functional water generator 1 according to the present invention is integrally disposed in a water storage tank attached to the toilet and the toilet is washed with functional water. This will be described with reference to FIG. By washing the toilet bowl in this way, the toilet can be kept hygienic without adding a separate drug or the like.

  That is, since the toilet set installed in the toilet is a place where toilets are used, it is very easy to get dirty. For example, if stool adheres and solidifies, or urine is stoned and deposited, it could not be easily removed by rubbing with a brush.

  In addition, in toilets that store water in the tank in advance for the purpose of pouring waste after stool into the sewage pipes, contamination can be prevented by mixing a commercially available cleaning agent such as a surfactant into the stored water. However, it was not very effective against dirt that had already adhered.

  Therefore, the functional water generating device 1 according to the present invention is arranged as shown in FIG. 11, for example, as a toilet cleaning device 36, and the water 31 stored in the tank 44 is circulated to the functional water generating device 1 to function the water storage. By using water, the dirt attached to the toilet can be oxidized and effectively removed. In FIG. 11, a black light 9 for irradiating the photocatalyst body 20 accommodated in the functional water generating device 1 with ultraviolet light and a water supply pump for supplying water 31 in the tank 44 from the water supply port 2. 32 and the oxygen supply pipe 4 for mixing oxygen into the water 31 are omitted.

  The functional water stored in the tank 44 is operated by operating the handle 42 so that the faucet 45 is released and the functional water flows from the communication pipe 43 to a toilet (not shown).

  Moreover, since the functional water has a strong sterilizing effect as suggested in Example 2, it is possible to reliably sterilize polluted bacteria adhering to the toilet bowl and the periphery of the toilet bowl and fungi in the stool. Can be kept clean.

  At the same time, functional water has an excellent deodorizing effect, so it can decompose and deodorize odors after stool trapped in the toilet and odors flowing back from the sewage pipe. The environment can be used hygienically and comfortably.

  Since the functional water that has flowed from the toilet together with the filth in this way is quickly brought into water and oxygen when it comes into contact with organic matter such as filth and dirt, there is no possibility of adversely affecting the environment.

  Since these effects are generated each time filth is flowed in the toilet, the toilet can be kept hygienic at all times, and the labor spent for cleaning the toilet can be drastically reduced.

(Viii) Example of use in a washing machine Next, an example in which functional water is brought into contact with clothing or fabric and sterilized and washed will be described. For example, the functional water generating apparatus 1 according to the present invention can be placed in a washing machine or the like and used for washing clothes and fabrics, thereby providing a sanitary state.

  For example, clothes are often worn for a long time, and a lot of sweat and oil secreted from the body are attached.

  Therefore, it is necessary to perform washing after wearing clothes, but it is difficult to say that washing with water alone is insufficient and effective.

  It is also possible to wash with laundry detergent, but it is also possible that components such as surfactants contained in the laundry detergent remain in clothing and become one of the causes of allergies.

  Therefore, the water supplied to the washing tub of the washing machine is the functional water generated by the functional water generator 1 according to the present invention, so that the attached dirt can be effectively removed and the bacteria can be sterilized. Can be made hygienic.

  In addition, a table cloth or a cleaning cloth will wipe off dirt due to its role, so that the dirt adheres and microorganisms are likely to grow, but it is washed with the washing machine according to the present invention. As a result, it is possible to maintain a hygienic state and to prevent wiping and spreading dirt and microorganisms.

  Furthermore, although the outer periphery of the washing tub is not normally visible, it is a place where dirt adheres and the propagation of various germs easily proceeds because there is no contact with the laundry. By attaching this apparatus to a washing machine, it is possible to prevent the growth of these stains and germs on the outer periphery of the washing tub.

(Ix) Example used for washing seed potato Next, an example in which functional water is brought into contact with the seed potato and sterilized and washed will be described. For example, the seedling before seeding on the seedbed is brought into contact with the functional water generated by the functional water generating apparatus 1 according to the present invention, so that seedling seedling growth inhibition due to bacteria or mold can be prevented.

  That is, when performing rice cultivation, it is necessary to grow seedlings for planting rice. However, since seeds germinate in the presence of water and air, microorganisms may propagate. Propagated microorganisms can inhibit the proper growth of seedlings and can spoil the seedlings.

  Therefore, it is necessary to sterilize the seed pods to be sown on the nursery, but there is a concern that the drug after being used for sterilization may flow out to the natural world and adversely affect the environment.

  Moreover, it is thought that the chemical | medical agent which has a general bactericidal ability has a bad influence not only on the growth of a plant.

  Then, the functional water produced | generated with the functional water production | generation apparatus 1 which concerns on this invention, and a seed pod are made to contact, and the microorganisms etc. which have adhered to the seed potato are sterilized, A medicinal effect remains and it has a bad influence on growth of a plant. There is no fear of giving it, and adverse effects on the environment can be prevented.

  Moreover, since it is not necessary to obtain a separate drug for sterilizing the seed pods, the cost required for rice cultivation can be reduced.

  In this way, by bringing the functional water generated by the functional water generator 1 into contact with the object to be cleaned, sterilization and cleaning can be performed while keeping the human body safe and hygienic.
