Description

  The present invention relates to an apparatus for producing magnetic active water containing nanobubbles and a method for producing magnetic active water containing nanobubbles.

  Dioxins and organic fluorine compounds (for example, perfluorooctasulfonic acid (PFOS) or perfluorooctanoic acid (PFOA)) are chemically stable substances, and have high heat resistance and chemical resistance (for example, acid resistance). Are better. Therefore, for example, organic fluorine compounds are widely used as industrial materials such as surfactants or antireflection films in semiconductor manufacturing. However, the more widely used organic fluorine compounds are, the more likely they are released to nature. As described above, since the organic fluorine compound is a chemically stable substance, once it is released into nature, it can cause serious environmental pollution. For example, organic fluorine compounds have been detected in polar bears, seals, and whales, and it has become clear that environmental pollution by organic fluorine compounds is becoming increasingly serious internationally.

  Therefore, in order to prevent environmental pollution, various apparatuses and methods for processing (eg, recovering and decomposing) organic fluorine compounds after being used as industrial materials have been developed.

  For example, biological treatment facilities (for example, various microbial tanks) or physical treatment facilities (for example, activated carbon adsorption towers, rapid filtration devices) have been conventionally used as purification facilities for water containing organic fluorine compounds and the like. . In the case of the biological treatment facility, the organic fluorine compound is taken into the metabolic pathway of the microorganism, and the organic fluorine compound is decomposed in the metabolic pathway. On the other hand, in the case of a physical treatment facility, after an organic fluorine compound is adsorbed on, for example, activated carbon, the organic fluorine compound is recovered from the activated carbon.

  In addition, a method of thermally decomposing an organic fluorine compound by heat-treating wastewater containing the organic fluorine compound has been conventionally used.

  By the way, it has been conventionally known that bubbles having a small diameter have various physiological functions, and researches on techniques for producing such bubbles and their effects are now underway. Attempts have also been made to decompose various organic substances using the bubbles.

  The bubbles can be classified into microbubbles, micronanobubbles and nanobubbles according to their diameters. Specifically, the microbubble is a bubble having a diameter of 10 μm to several tens of μm at the time of its generation, the micro-nano bubble is a bubble having a diameter of several hundred nm to 10 μm at the time of its generation, and the nanobubble is Bubbles having a diameter of several hundred nm or less at the time of generation. Note that a part of the microbubble may be changed to a micro / nanobubble by the contraction movement after the generation. Nanobubbles have the property that they can exist in a liquid for a long period of time.

  For example, conventionally, various utilization methods of nanobubbles and various apparatuses utilizing nanobubbles are known (see, for example, Patent Document 1). More specifically, in Patent Document 1, nanobubbles exhibit surface-active action and bactericidal action by reducing buoyancy, increasing surface area, increasing surface activity, generating a local high-pressure field, or realizing electrostatic polarization. It is described. Furthermore, Patent Document 1 describes a technique for cleaning various objects and a technique for purifying polluted water using the surface-active action and bactericidal action of nanobubbles. Furthermore, Patent Document 1 describes a method for recovering fatigue of a living body using nanobubbles. In Patent Literature 1, nanobubbles are produced by electrolyzing water and applying ultrasonic vibration to the water.

  Conventionally, a method for producing nanobubbles using a liquid as a raw material is known (see, for example, Patent Document 2). In the liquid, the production method includes 1) a step of decomposing and gasifying a part of the liquid, 2) a step of applying ultrasonic waves to the liquid, or 3) a step of decomposing and gasifying a part of the liquid; A step of applying ultrasonic waves to the liquid. It is described that an electrolysis method or a photolysis method can be used as a step of decomposing and gasifying a part of the liquid.

Conventionally, a waste liquid treatment apparatus using microbubbles (ozone microbubbles) made of ozone gas has been used (see, for example, Patent Document 3). In the waste liquid treatment apparatus, microbubbles made of ozone gas are produced by mixing the ozone gas produced by the ozone generator and the waste liquid using a pressure pump. The microbubbles react with the organic matter in the waste liquid, so that the organic matter in the waste liquid is oxidatively decomposed.

  However, the above-described conventional apparatus and method have a problem that a chemically stable substance (for example, an organic fluorine compound) cannot be efficiently decomposed.

  For example, when the biological treatment facility is used, there is no microorganism that can efficiently decompose the organic fluorine compound. Therefore, there is a problem that a large amount of the organic fluorine compound cannot be treated.

  Moreover, when using the said physical processing equipment, for example, since it is necessary to replace | exchange activated carbon frequently, it has the problem that an operation | work is complicated, and many costs are needed in order to reproduce | regenerate activated carbon. Has the problem. The physical treatment equipment is basically equipment for recovering the organic fluorine compound, and is not equipment for decomposing the organic fluorine compound. Therefore, when using the said physical processing equipment, there exists a problem that the further equipment (for example, heating apparatus) for decomposing | disassembling an organic fluorine compound is required.

  Moreover, when heat-treating wastewater containing an organic fluorine compound, the organic fluorine compound is stable to heat, so it is necessary to heat it to about 1000 ° C. or higher for thermal decomposition. Therefore, when heat-treating wastewater containing an organic fluorine compound, there is a problem that a further facility for heating the wastewater to a high temperature is required and a large amount of fuel is required. Moreover, since many carbon dioxides are discharged | emitted to the natural world in the process of heat processing, it has the problem of causing global warming.

  In addition, when the bubbles are used, various organic substances can be decomposed by the bubbles, but a chemically stable substance such as an organic fluorine compound cannot be decomposed efficiently. Therefore, there is a problem that a large amount of the organic fluorine compound cannot be treated.

  The present invention has been made in view of the above-described conventional problems, and its object is to produce a nanobubble-containing magnetic active water and a method for producing nanobubble-containing magnetic active water that can efficiently decompose a chemically stable substance. Is to provide.

As a result of intensive studies in view of the above problems, the present inventors have found the following 1) to 5), and have completed the present invention. That means
1) The magnetic active water containing nanobubbles has a larger negative charge than the water containing nanobubbles, and therefore the magnetic active water containing nanobubbles has a strong oxidizing power,
2) Nanobubble-containing magnetic active water generates much more unstable free radicals than nanobubble-containing water due to the synergistic effect of magnetic force and nanobubbles. As a result, the magnetic active water containing nanobubbles has a strong oxidizing power,
3) The magnetic active water containing nanobubbles has a stronger oxidizing power than the water containing nanobubbles. Therefore, the magnetic active water containing nanobubbles can efficiently oxidize and decompose hardly decomposable organic fluorine compounds,
4) In order to completely treat the hardly decomposable organic fluorine compound, first, the hardly decomposable substance (for example, the organic fluorine compound) is oxidatively decomposed (primary treatment) in the magnetic active water containing nanobubbles, and then For example, it is effective to adsorb to activated carbon (secondary treatment),
5) Since the magnetic active water containing nanobubbles activates microorganisms more than nanobubble-containing water, it should be effective for wastewater treatment using microorganisms.

  The nanobubble-containing magnetic active water production apparatus of the present invention is configured to produce a microbubble-containing water by mixing and shearing a liquid and a gas, and further shearing the microbubble-containing water to produce a nanobubble-containing water. A second gas shearing section, and magnetically active water producing means for applying a magnetic field to the microbubble-containing water or the nanobubble-containing water.

  According to the above configuration, the microbubble-containing water can be produced by the first gas shearing section, and the nanobubble-containing water can be produced by the second gas shearing section using the microbubble-containing water. . That is, nanobubble-containing water can be efficiently produced by a series of continuous processes. Moreover, according to the said structure, since a magnetic field is applied with respect to microbubble containing water or nanobubble containing water, the nanobubble containing water which is a final product can be made into magnetic active water. In other words, the nanobubble-containing water that is the final product can be provided with activity (magnetic activity) as magnetically active water. That is, the nanobubble-containing magnetic active water can be provided with both the oxidizing ability of free radicals generated by nanobubbles and the oxidizing ability of active oxygen generated in magnetic active water.

  Both microbubbles and nanobubbles generate free radicals, whereas microbubbles exist in water for several hours, whereas nanobubbles can exist in water for over a week. Therefore, if nanobubbles are used, the oxidation ability of free radicals generated by nanobubbles can be maintained for one week or longer. That is, the nanobubble-containing magnetic active water can maintain both the oxidizing ability of free radicals and the oxidizing ability of active oxygen generated in the magnetic active water for one week or more.

  In the nanobubble-containing magnetic active water producing apparatus of the present invention, the magnetic active water preparation means is supplied with microbubble-containing water or nanobubble-containing water via a first pipe, and the first pipe includes the first pipe. It is preferable that a pipe diameter adjusting means capable of changing the size of at least a part of the lumen cross section is provided.

  According to the said structure, the magnitude | size of the cross section of a pipe lumen can be changed in the at least one part area | region of 1st piping by the said pipe diameter adjustment means. As a result, it is possible to adjust the amount of microbubble-containing water or nanobubble-containing water supplied to the magnetic active water production means via the first pipe. That is, the flow rate of microbubble-containing water or nanobubble-containing water when magnetism is applied by the magnetic active water preparation means can be adjusted, and the microbubbles when magnetism is applied by the magnetic active water preparation means The flow of the water containing or nanobubble containing water can be made into a phase flow instead of a turbulent flow.

  In order to produce magnetic active water efficiently, it is necessary to adjust the flow rate of the liquid to which a magnetic field is applied. Therefore, according to the said structure, a magnetic active water can be produced efficiently. Moreover, if the flow of microbubble-containing water or nanobubble-containing water is a phase flow, a magnetic field can be applied evenly to the microbubble-containing water or nanobubble-containing water. As a result, magnetically active water can be produced efficiently.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, the magnetic active water producing means is a flow path arranged so that the first surface that functions as the S pole of the magnet and the second surface that functions as the N pole of the magnet face each other. It is preferable that the microbubble-containing water or the nanobubble-containing water pass through the flow path.

  According to the said structure, the said magnetic active water preparation means has a flow path arrange | positioned so that the 1st surface which functions as a south pole of a magnet, and the 2nd surface which functions as a north pole of a magnet may oppose. . Therefore, a magnetic field can be applied to the microbubble-containing water or the nanobubble-containing water by passing the microbubble-containing water or the nanobubble-containing water through the channel. As a result, the microbubble-containing water or nanobubble-containing water can be made into magnetically active water. In other words, microbubble-containing water or nanobubble-containing water can be provided with activity as magnetically active water.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, the distance between the first surface and the second surface is preferably 30 mm or less.

  According to the said structure, a magnetic field can be equally applied to the microbubble containing water or nanobubble containing water which has passed through the said flow path. As a result, the microbubble-containing water or nanobubble-containing water can be converted into magnetically active water more efficiently.

  The nanobubble-containing magnetic active water producing apparatus of the present invention preferably has a gas amount adjusting means for supplying the gas at 1.2 liter / min or less to the first gas shearing part.

  According to the said structure, gas can be supplied at 1.2 liter / min or less with respect to a 1st gas shear part by the said gas quantity adjustment means. And, as specified in the examples described later, if a gas is supplied to the first gas shearing part at the above ratio, a large amount of nanobubbles can be produced.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, it is preferable that the cross section inside the first gas shearing portion is an ellipse or a true circle.

  According to the above configuration, since the shape of the cross section inside the first gas shearing portion is an ellipse or a true circle, the mixture of the gas and the liquid is applied to the inner surface of the first gas shearing portion. Rotational motion can be performed along. That is, the mixture of the gas and the liquid can be rotated at a high speed inside the first gas shearing portion in a state where no swirling turbulence occurs. As a result, since the gas can be efficiently sheared, a large amount of microbubbles can be produced at the first gas shearing portion. If a large amount of microbubbles can be produced in the first gas shearing portion, a large amount of nanobubbles can be produced from the microbubbles in the second gas shearing portion.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, it is preferable that two or more grooves are provided on the inner surface of the first gas shearing portion.

  According to the above configuration, when the mixture of the gas and the liquid is rotated in the first gas shearing portion by forming a groove in the inner surface of the first gas shearing portion, the swirl is performed. Turbulence can be prevented from occurring. As a result, a large amount of microbubbles can be produced at the first gas shearing portion. If a large amount of microbubbles can be produced in the first gas shearing portion, a large amount of nanobubbles can be produced from the microbubbles in the second gas shearing portion.

  In the nanobubble-containing magnetic active water producing apparatus of the present invention, the depth of the groove is preferably 0.3 mm to 0.6 mm, and the width of the groove is preferably within 0.8 mm.

  According to the said structure, it can prevent that a turning turbulent flow arises more reliably.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, the liquid is supplied to the first gas shearing part via a second pipe, and the microbubble-containing water is discharged via a third pipe, The area of the cross section of the lumen of the second pipe is preferably larger than the area of the cross section of the lumen of the third pipe.

  According to the said structure, while being able to produce a lot of microbubbles, a lot of nanobubbles can be produced using the said microbubble. Generally, in order to stably produce microbubbles at the first gas shearing section, it is necessary to increase the discharge pressure of the microbubble-containing water from the first gas shearing section. Therefore, the area of the cross section in the lumen of the second pipe for supplying the liquid to the first gas shearing section is the lumen of the third pipe for discharging the microbubble-containing water from the first gas shearing section. (In other words, if the discharge port of the microbubble-containing water is made smaller than the supply port of the liquid), the discharge of the microbubble-containing water from the first gas shearing portion The pressure can be increased. As a result, a large amount of microbubbles can be produced at the first gas shearing portion. And if a lot of microbubbles can be produced in the 1st gas shearing part, a lot of nanobubbles can be produced in the 2nd gas shearing part using the microbubble.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, the gas is supplied to the inside of the first gas shearing part via a fourth pipe, and the fourth pipe is provided on the inner surface of the first gas shearing part. It is preferable that it is connected to the first gas shearing part so as to form an angle of 18 degrees (in other words, an incident angle to the inner side surface of the first gas shearing part is 18 degrees). The value of 18 degrees is the optimum incident angle, and the incident angle may be approximately 18 degrees. Specifically, the incident angle is preferably 17 degrees to 19 degrees.

  According to the above configuration, judging from the experimental results, when the incident angle is 18 degrees, efficient high-speed shearing between gas and liquid occurs, and a large number of microbubbles can be produced. That is, a large amount of microbubbles can be produced by the first gas shearing part. And if the said microbubble is used, a large amount of nanobubbles can be produced in the second gas shearing part.

  In the nanobubble-containing magnetic active water production apparatus of the present invention, the thickness of the partition wall of the first gas shearing part is preferably 6 mm to 12 mm.

  According to the said structure, since the partition of the 1st gas shearing part is formed thickly, a 1st gas shearing part does not vibrate. That is, even if the mixture of the gas and the liquid swirls inside the first gas shearing portion, the first gas shearing portion does not vibrate thereby. Therefore, since the kinetic energy of the mixture swirling inside the first gas shearing portion is not lost by being propagated to the outside (for example, external gas) as vibration, the mixture is rotated at high speed. Can do. As a result, microbubbles can be efficiently produced at the first gas shearing portion.

  The nanobubble-containing magnetic active water production apparatus of the present invention preferably has a third gas shearing section that further shears the microbubble-containing water or the nanobubble-containing water to which a magnetic field is applied by the magnetic active water preparation means.

  According to the above configuration, the size of nanobubbles contained in the finally produced nanobubble-containing magnetic active water can be reduced, and the amount of nanobubbles contained in the finally produced nanobubble-containing magnetic active water can be increased. Can be made. As a result, the oxidation ability of nanobubble-containing magnetic active water can be increased.

  In order to solve the above problems, the method for producing nanobubble-containing magnetic active water of the present invention further comprises a first gas shearing step of mixing and shearing a liquid and a gas to produce microbubble-containing water, and the microbubble-containing water. It has the 2nd gas shearing process which produces nanobubble containing water by shearing, and the magnetic active water preparation process which applies a magnetic field to the said microbubble containing water or the said nanobubble containing water.

  According to the above configuration, the microbubble-containing water can be produced by the first gas shearing process, and the nanobubble-containing water can be produced by the second gas shearing process using the microbubble-containing water. . That is, nanobubble-containing water can be efficiently produced by a series of continuous processes. Moreover, according to the said structure, since it has the magnetic active water preparation process which applies a magnetic field with respect to microbubble containing water or nanobubble containing water, the nanobubble containing water which is a final product can be made into magnetic active water. In other words, the nanobubble-containing water that is the final product can be provided with activity as magnetically active water. That is, the nanobubble-containing magnetic active water can be provided with both the oxidizing ability of free radicals generated by nanobubbles and the oxidizing ability of active oxygen generated in magnetic active water.

  In the nanobubble-containing magnetic active water production method of the present invention, the first gas shearing step includes a liquid stirring step of stirring the liquid with a pump, a gas mixing step of adding the gas to the stirred liquid, In the gas mixing step, the gas is preferably added to the liquid after the output of the pump reaches a maximum value.

  According to the above configuration, the pump can be prevented from being damaged by gas. That is, damage to the pump due to the occurrence of cavitation can be prevented. As a result, a large amount of microbubbles can be produced in the first gas shearing process. In the second gas shearing step, a large amount of nanobubbles can be produced from the large amount of microbubbles.

  In the nanobubble-containing magnetic active water production method of the present invention, in the gas mixing step, the gas is preferably added to the liquid after 60 seconds from the start of operation of the pump.

  According to the above configuration, since the output of the pump surely reaches the maximum value, a large amount of microbubbles can be produced in the first gas shearing step, and a large amount in the second gas shearing step. Nanobubbles can be produced.

  In the nanobubble-containing magnetic active water production method of the present invention, the liquid is preferably clean water, waste water, bath water, culture solution or crude oil.

  According to the said structure, while being able to generate nanobubbles in clean water, waste water, bathtub water, a culture solution, or crude oil, magnetic activity can be provided to these liquids. As a result, these liquids can be oxidized, and at the same time, nanobubbles can be contained in these liquids.

  The nanobubble-containing magnetic active water production method of the present invention preferably includes a third gas shearing step of further shearing the microbubble-containing water or the nanobubble-containing water to which a magnetic field has been applied in the magnetic active water preparation step.

  According to the above configuration, the size of nanobubbles contained in the finally produced nanobubble-containing magnetic active water can be reduced, and the amount of nanobubbles contained in the finally produced nanobubble-containing magnetic active water can be increased. Can be made. As a result, the oxidation ability of nanobubble-containing magnetic active water can be increased.

  The nanobubble-containing magnetic active water production apparatus of the present invention, as described above, further shears the microbubble-containing water by mixing and shearing the liquid and the gas to produce the microbubble-containing water and the microbubble-containing water. It has a 2nd gas shear part which produces nanobubble content water, and a magnetic active water production means which applies a magnetic field to the microbubble content water or the nanobubble content water.

  The nanobubble-containing magnetic active water production method of the present invention includes a first gas shearing step of mixing and shearing a liquid and a gas to produce microbubble-containing water as described above, and further shearing the microbubble-containing water. The second gas shearing step for producing nanobubble-containing water and the magnetically active water producing step for applying a magnetic field to the microbubble-containing water or the nanobubble-containing water.

  Therefore, since the nanobubble-containing magnetic active water produced by the apparatus and method of the present invention has a strong oxidizing action, there is an effect that a chemically stable substance can be efficiently decomposed.

  The nanobubble-containing magnetic active water produced by the apparatus and method of the present invention can be easily oxidized by simply using treated water such as waste water as nanobubble-containing magnetic active water. As a result, there is an effect that treatment such as decolorization of treated water which has been conventionally performed using activated carbon can be easily performed without using activated carbon.

  In addition, when activated carbon is used in combination, the nanobubble-containing magnetic active water enters the small pores of the activated carbon. As a result, the organic substance already adsorbed on the activated carbon can be oxidatively decomposed, and the organic substance adsorbed on the activated carbon can be decomposed by the microorganism by strongly activating the microorganism propagated on the activated carbon. Therefore, there is an effect that the adsorption ability of the activated carbon that has once lost the adsorption ability (generally, the activated carbon has passed through) can be restored.

  In addition, since the organic matter in the treated water can be strongly oxidized, the chemical oxygen demand can be reduced even in the treated water where it is difficult to reduce the chemical oxygen demand by the conventional technique.

[Embodiment 1]
An embodiment of the present invention will be described with reference to FIG.

  The nanobubble containing magnetic active water manufacturing apparatus of this Embodiment can produce the magnetic active water containing nanobubble. In the present specification, the term “nanobubble” means a bubble having a diameter of several hundred nm or less when it is generated. Further, in this specification, “magnetically active water” is intended to mean a liquid (for example, water) activated by the energy of a magnetic field by allowing water to pass through, for example, an artificially generated magnetic field. Further, in this specification, “magnetic activity” intends the activity of a liquid (for example, water) by the action of magnetic lines of force.

  The nanobubble-containing magnetic active water production apparatus 17 of the present embodiment includes a tank 1, a nanobubble generator 47, a first magnetic active water preparation unit 9 (magnetic active water preparation unit), and a first pipe diameter adjustment unit 34 (pipe diameter adjustment unit). It has. Each configuration will be described below.

  First, the tank 1 will be described.

  The tank 1 is used as a space for storing a liquid, which is one of materials for producing nanobubble-containing magnetic active water, and also used as a space for discharging the produced nanobubble-containing magnetic active water. In addition, as a space for discharging the produced nanobubble-containing magnetic active water, a tank (not shown) different from the tank 1 can be used.

  The tank 1 is not particularly limited as long as it can hold the liquid at least temporarily. The size and material of the tank 1 can be selected appropriately according to the purpose.

  As described above, a liquid for producing nanobubble-containing magnetic active water is stored in the tank 1. It does not specifically limit as said liquid, The kind of liquid can be selected according to the objective. For example, the liquid includes clean water, waste water (eg, organic fluorine compound-containing waste water), bath water (eg, therapeutic bath water), reuse water, culture fluid (eg, microorganism or cell culture fluid, fish Water used for aquaculture, water used for plant cultivation, etc.), chemicals, cosmetics, organic solvents, heavy oil, crude oil, or bioethanol can be used, but is not limited thereto. If it is the nanobubble containing magnetic active water of this Embodiment, the chemically stable substance contained in these liquids can be decomposed | disassembled efficiently.

  Next, the nanobubble generator 47 will be described.

  The nanobubble generator 47 includes a pipe 2, a first gas shearing section 4, a second gas shearing section 5, a third gas shearing section 14, a pipe 7 (fourth pipe) having a gas-liquid mixing circulation pump 3 (pump), and An electric needle valve 8 (gas amount adjusting means) is provided.

  A pipe 2 and a pipe 7 are connected to the first gas shearing part 4. Then, the liquid is supplied to the first gas shearing part 4 through the pipe 2, and the gas is supplied to the first gas shearing part 4 through the pipe 4. And the said liquid and said gas are mixed and sheared in the said 1st gas shearing part 4, As a result, microbubble containing water is produced.

  The liquid is supplied into the first gas shearing section 4 by operating the gas-liquid mixing circulation pump 3. Further, the gas supply into the first gas shearing section 4 and the adjustment of the gas supply amount are adjusted by the opening / closing operation of the electric needle valve 8.

  The timing of the opening / closing operation of the electric needle valve 8 is not particularly limited. For example, first, the operation of the gas-liquid mixing circulation pump 3 is started to introduce a liquid into the first gas shearing section 4 and to stir the liquid (liquid stirring step). Thereafter, the electric needle valve 8 is opened after the time when the output of the gas-liquid mixing circulation pump 3 reaches the maximum value, thereby supplying gas into the first gas shearing part 4 (gas mixing step). Is preferred. Further, the electric needle valve 8 is opened after 60 seconds from the start of the operation of the gas-liquid mixing / circulation pump 3, thereby supplying gas into the first gas shearing section 4 (gas mixing step). It is more preferable.

  Although it is possible to open the electric needle valve 8 at the start of operation of the gas-liquid mixing circulation pump 3, in this case, the gas-liquid mixing circulation pump 3 causes a cavitation phenomenon. As a result, the gas-liquid mixing circulation pump 3 May be damaged. However, if it is the said structure, since it can prevent that the gas-liquid mixing circulation pump 3 raise | generates a cavitation phenomenon, it can prevent that the gas-liquid mixing circulation pump 3 is damaged as a result.

  The amount of gas supplied into the first gas shearing part 4 by opening the electric needle valve 8 is not particularly limited. For example, it is preferable to supply gas to the first gas shearing portion 4 at 1.2 liters / minute or less. Although clearly described in the examples described later, a large amount of nanobubble-containing water can be efficiently produced with the above-described configuration.

  As shown in FIG. 1, gas is supplied to the first gas shearing section 4 via a pipe 7 (fourth pipe). When the pipe 7 is connected to the one gas shearing part 4, the connection position of the pipe 7 on the first gas shearing part 4, the connection angle of the pipe 7 to the first gas shearing part 4, etc. are not particularly limited.

  For example, FIG. 11 shows a cross section of the first gas shearing portion 4 when the cross section is a circle. In addition, the arrow in FIG. 11 has shown the direction of the rotational motion (swirling motion) of gas-liquid mixture (microbubble containing water). At this time, as shown in FIG. 11, the pipe 7 is connected to the side surface of the first gas shearing portion 4 and also the inner side surface of the first gas shearing portion 4 (in other words, the first gas shearing portion 4 It is preferable that the connection is made at an angle of about 18 degrees with respect to the tangent to the inner surface. In other words, when considering the local location at the connection location of the pipe 7, the pipe 7 is connected to the inner surface of the first gas shearing portion 4 so as to form an angle of 18 degrees with respect to the moving direction of the gas / liquid mixture. It is preferred that

  In order to efficiently produce microbubbles, it is necessary to efficiently shear gas. At this time, the liquid is rotated at an extremely high speed to form a negative pressure portion, and a gas is introduced into the negative pressure portion. The gas is efficiently sheared by the difference between the rotation speeds of the gas and the liquid. The inventors of the present application have found that the gas shearing efficiency varies depending on the gas intake angle, that is, the gas incident angle with respect to the liquid in the first gas shearing portion 4. In this case, when the incident angle is 18 degrees, the shearing efficiency of the gas is the highest, so that the largest number of microbubbles can be produced.

  Next, a process of producing nanobubble-containing water by the nanobubble generator 47 will be described. In general, the nanobubble-containing water is produced through two steps (a first gas shearing step and a second gas shearing step). Hereinafter, the first gas shearing process and the second gas shearing process will be described in more detail.

[First gas shearing process]
In the first gas shearing step, microbubble-containing water is produced from the gas and the liquid.

  In the first gas shearing process, in the first gas shearing section 4, the pressure of the mixture of the gas and the liquid is controlled hydrodynamically using the gas-liquid mixing circulation pump 3, and gas is supplied to the negative pressure section. Is inhaled. The “negative pressure part” means a region where the pressure is smaller than that of the surroundings in the mixture of gas and liquid. Then, fine microbubbles are generated by shearing the gas while moving the mixture at high speed to form a negative pressure portion. In other words, the liquid and the gas are effectively self-mixed and dissolved and pumped. Thereby, microbubble-containing water containing finer microbubbles can be formed.

Although it does not specifically limit as said gas-liquid mixing circulation pump 3, It is preferable that it is a pump of the high head of 40 m or more (pressure of 4 kg / cm < ² >). The gas-liquid mixing circulation pump 3 is preferably a two-pole pump with stable torque. According to the said structure, it is possible to apply a desired pressure with respect to the microbubble containing water in the 1st gas shearing part 4, As a result, the microbubble contained in microbubble containing water is sheared more finely be able to.

  Moreover, in the gas-liquid mixing circulation pump 3, it is preferable that the pressure of the pump is controlled. For example, it is preferable that the rotation speed of the gas-liquid mixing circulation pump 3 is controlled by a rotation control unit (not shown) such as an inverter. The rotation control unit can be further controlled by a sequencer (not shown). According to the said structure, it becomes possible to apply a desired pressure with respect to the microbubble containing water in the said 1st gas shearing part 4, As a result, the microbubble contained in microbubble containing water is made into a desired size. Can be aligned.

  Although the material of the said 1st gas shear part 4 is not specifically limited, It is preferable that they are stainless steel, a plastics, or resin. Of the above materials, stainless steel is most preferred. According to the said structure, while being able to prevent an impurity mixing in microbubble containing water, it can prevent that the 1st gas shearing part 4 vibrates.

  Moreover, the thickness (thickness of the partition wall) of the first gas shearing portion 4 is not particularly limited, but is preferably 6 mm to 12 mm. In general, if the thickness of the first gas shearing portion 4 is thin, the first gas shearing portion 4 vibrates due to the movement of the microbubble-containing water in the first gas shearing portion 4. That is, since the kinetic energy of the microbubble-containing water propagates to the outside as vibration and is lost, the high-speed flow motion of the microbubble-containing water decreases, and as a result, the shear energy decreases. However, according to the said structure, since the vibration of the 1st gas shearing part 4 can be prevented, a microbubble can be produced efficiently.

  Next, the mechanism by which the first gas shearing part 4 having the gas-liquid mixing circulation pump 3 generates microbubbles will be described in detail.

  First, in the said 1st gas shearing part 4, the mixed phase swirl | flow which consists of the liquid and gas which are the structural components of microbubble containing water is generated. Specifically, a wing called an impeller is rotated at an ultra high speed to generate a mixed phase swirl composed of a liquid and a gas. At this time, a gas cavity that swirls at a high speed is formed at the center of the first gas shearing portion 4.

  Next, the gas cavity is narrowed in a tornado shape by pressure to generate a rotating shear flow that swirls at a higher speed. At this time, gas is automatically supplied to the gas cavity using the negative pressure of the gas cavity. Then, the multiphase swirl is rotated while further cutting and crushing the microbubbles. In addition, the said cutting | disconnection and grinding | pulverization arises by the difference in the rotational speed of the gas-liquid two-phase fluid in the inside and outside of the exit of the 1st gas shearing part 4. FIG. The difference in rotational speed is preferably 500 to 600 revolutions / second.

  That is, in the first gas shearing part 4, a negative pressure part is formed by moving the microbubble-containing water at high speed by the gas-liquid mixing circulation pump 3, and the pressure of the microbubble-containing water is controlled hydrodynamically. The gas is supplied to the negative pressure part. As a result, the first gas shearing part 4 can generate microbubbles. In other words, the microbubble-containing water can be produced by using the gas-liquid mixing / circulation pump 3 to pump the liquid and gas while effectively self-mixing and dissolving them.

  The shape of the cross section of the lumen of the first gas shearing portion 4 is not particularly limited, but is preferably elliptical, and most preferably true round. Moreover, it is preferable that the lumen | bore surface of the said 1st gas shearing part 4 is formed by mirror surface finishing. According to the said structure, since the friction of the internal surface of the 1st gas shearing part 4 is small, while being able to rotate the mixture of gas and a liquid at high speed, a gas can be sheared efficiently. As a result, many fine microbubbles can be generated, and finally many nanobubbles can be generated.

  Moreover, it is preferable that a groove is provided on the inner surface (lumen surface) of the first gas shearing portion 4. Further, the number of the grooves is not particularly limited, but two or more grooves are preferably provided. Moreover, the said groove | channel should just have a concave shape formed on the internal surface of the 1st gas shearing part 4, The shape is not specifically limited. For example, the groove preferably has a depth of approximately 0.3 mm to 0.6 mm and a width of approximately 0.8 mm or less. According to the above configuration, the generation of the swirling turbulent flow of the mixture of the liquid and the gas in the first gas shearing section 4 can be controlled, so that many fine microbubbles can be generated and finally Many nanobubbles can be generated.

  Further, liquid is supplied to the first gas shearing section 4 through the pipe 2, and microbubble-containing water is discharged through the pipe 51. At this time, the area of the cross section of the lumen of the pipe for supplying the liquid (second pipe) is larger than the area of the cross section of the lumen of the pipe for discharging the microbubble-containing water (third pipe). preferable. According to the said structure, since the discharge pressure of microbubble containing water can be raised, a microbubble can be generated stably.

[Second gas shearing process]
In the second gas shearing step, nanobubble-containing water is produced from the microbubble-containing water produced in the first gas shearing step. More specifically, the microbubble-containing water produced by the first gas shearing section 4 is further sheared by the second gas shearing section 5, thereby producing nanobubble-containing water.

  In addition, the 3rd gas shearing part 14 can further be provided as needed. If the 3rd gas shearing part 14 is provided, while the magnitude | size of the nanobubble produced by the 2nd gas shearing part 5 can be made still smaller, the quantity of nanobubble can be increased. The installation position of the third gas shearing portion 14 is not particularly limited. For example, it can also be installed downstream of the first magnetic active water preparation unit 9 described later, and can also be installed upstream of the first magnetic active water preparation unit 9.

  Microbubble-containing water is pumped from the first gas shearing section 4 to the second gas shearing section 5 and further to the third gas shearing section 14 by the gas-liquid mixing circulation pump 3. When the microbubble-containing water is pumped from the first gas shearing section 4 to the second gas shearing section 5 and further to the third gas shearing section 14 through the pipe, the microbubble-containing water is pumped. It is preferable that the diameter of the pipe decreases gradually or stepwise in the direction. According to the above configuration, the microbubble-containing water can be thinned like a tornado while performing fluid motion at a higher speed. In other words, it is possible to generate a rotating shear flow that swirls at a higher speed. As a result, nanobubbles can be efficiently generated from microbubbles, and an ultra-high temperature extreme reaction field can be formed in nanobubble-containing water.

  When the above-mentioned extreme reaction field is formed, the water containing nanobubbles locally becomes a high-temperature and high-pressure state, and unstable free radicals are generated locally, and at the same time, heat is generated. A free radical is an atom or molecule having an unpaired electron, and attempts to stabilize by taking electrons from other atoms or molecules. Therefore, nanobubble-containing water containing free radicals exhibits a strong oxidizing power. Therefore, according to the said structure, organic substance etc. can be oxidatively decomposed | disassembled by the effect | action of a free radical.

  Moreover, it is preferable that the 2nd gas shearing part 5 and the 3rd gas shearing part 14 are formed with stainless steel, a plastics, or resin. According to the said structure, the material of the said 2nd gas shear part 5 and the 3rd gas shear part 14 can be selected according to the intended purpose of nanobubble containing water. For example, in the pharmaceutical industry, it is necessary to avoid contamination of drugs with impurities. In this case, if it is the said structure, since the possibility that the material of the 2nd gas shearing part 5 and the 3rd gas shearing part 14 will mix is low, manufactured nanobubble containing water is used for manufacture of a pharmaceutical, ie, pharmaceutical. Can do.

  Moreover, the shape of the cross section of the lumen of the second gas shearing portion 5 and the third gas shearing portion 14 is preferably an elliptical shape, and most preferably a true circle. According to the above configuration, since the resistance (friction) of the inner surfaces of the second gas shearing portion 5 and the third gas shearing portion 14 is small, the microbubble-containing water can be swirled at a high speed and the microbubble-containing water can be efficiently used. It can shear well and, as a result, many nanobubbles can be generated.

  Moreover, it is preferable that the 2nd gas shearing part 5 and the 3rd gas shearing part 14 have a small hole with a defined size and shape. The diameter of the opening of the small hole is not particularly limited, but is preferably 4 mm to 9 mm. According to the above configuration, the swirling motion of the bubble-containing water inside the second gas shearing portion 5 and the third gas shearing portion 14 can be controlled. That is, according to the said structure, generation | occurrence | production of the turning turbulent flow inside the said 2nd gas shearing part and a 3rd gas shearing part is controllable. As a result, nanobubbles can be stably generated by the second gas shearing portion and the third gas shearing portion. The specific size of the small hole can be determined by the pump maximum suction value, the motor output value, and the pump discharge pressure value.

  In addition, although it does not specifically limit as a concrete structure of the gas-liquid mixing circulation pump 3, the 1st gas shearing part 4, the 2nd gas shearing part 5, and the 3rd gas shearing part 14 mentioned above, For example, using a commercially available thing Is possible. More specifically, for example, Bavidas HYK type manufactured by Kyowa Kikai Co., Ltd. can be used.

  Next, the first pipe diameter adjusting unit 34 will be described.

  The nanobubble-containing water produced by the second gas shearing unit 5 is then introduced into the first pipe diameter adjusting unit 34.

  In the nanobubble-containing magnetic active water manufacturing apparatus of the present embodiment, the first pipe diameter adjusting unit 34 adjusts the flow rate of the nanobubble-containing water introduced into the first magnetic active water preparation unit 9 described later, and the second gas shearing. The flow of the nanobubble-containing water discharged as a turbulent flow from the unit 5 is adjusted to a phase flow state. Thereby, the magnetic activity can be efficiently imparted to the nanobubble-containing water by the first magnetic active water preparation unit 9.

  Below, the specific structure of the 1st piping diameter adjustment part 34 is demonstrated.

  In the nanobubble-containing magnetic active water producing apparatus of the present embodiment, the first pipe diameter adjusting unit 34 is provided in the pipe 50 (first pipe) that connects the second gas shearing unit 5 and the first magnetic active water producing unit 9. Yes.

  The first pipe diameter adjusting unit 34 may be any one that can change the size of at least a part of the lumen cross section of the pipe 50, and the specific configuration thereof is not particularly limited.

  For example, as shown in FIGS. 12 (a) and 12 (b), the first pipe diameter adjusting section 34 can be formed by a pipe having a cylindrical shape. As shown in FIG. 12A, a flange 33 and a flange 35 are provided at each end of the pipe 50. A flange 33 and a flange 35 are also provided at each end of the first pipe diameter adjusting section 34. Further, the flange 33 and the flange 35 are provided with bolt holes 65. And as shown in FIG.12 (b), by attaching and detaching a volt | bolt to the said bolt hole 65, the flange 33 with which the piping 50 was equipped, the flange 33 with which the 1st piping diameter adjustment part 34 was equipped, and piping The flange 35 provided in 50 and the flange 35 provided in the first pipe diameter adjusting unit 34 can be attached and detached. As a result, the first pipe diameter adjusting section 34 connected between the ends of the pipe 50 can be replaced. At this time, a plurality of first pipe diameter adjusting sections 34 having different cylindrical shapes, that is, cylindrical shapes having different cross-sectional diameters, are prepared, and a desired first pipe diameter adjusting section 34 is selected from these. If the first pipe diameter adjusting section 34 is connected between the ends of the pipe 50, the lumen cross section of at least a part of the pipe 50 can be changed to a desired size. Note that the shape and size of the flange 33 and the flange 35 can be appropriately selected according to the shape and size of the cross section of the first pipe diameter adjusting portion 34.

  When the 1st piping diameter adjustment part 34 is formed by cylindrical piping, the length of the said 1st piping diameter adjustment part 34 in the direction through which nanobubble content water flows is not specifically limited, It can set suitably. For example, the length of the first pipe diameter adjusting unit 34 is preferably 10 times or more the diameter of an opening opened in the flange 6 described later. The length of the first pipe diameter adjusting section 34 is more preferably 10 times or more the diameter of the cross section of the first pipe diameter adjusting section 34 having a cylindrical shape.

  According to the said structure, after making the nanobubble containing water introduce | transduced in the 1st piping diameter adjustment part 34 into a turbulent flow into a phase flow reliably, the said nanobubble containing water is discharged to the 1st magnetic active water preparation part 9 side. Can do.

  Next, the first magnetic active water preparation unit 9 will be described.

  In the nanobubble-containing magnetic active water production apparatus of the present embodiment, the nanobubble-containing water that has passed through the first pipe diameter adjusting unit 34 is introduced into the first magnetic active water preparation unit 9.

  In the nanobubble-containing magnetic active water production apparatus of the present embodiment, the first magnetic active water production unit 9 applies a magnetic field to the nanobubble-containing water produced by the second gas shearing unit 5. As a result, activity (magnetic activity) as magnetic active water can be imparted to the nanobubble-containing water.

  Below, the specific structure of the 1st magnetic active water preparation part 9 is demonstrated.

  In the nanobubble-containing magnetic active water production apparatus of the present embodiment, the first magnetic active water preparation unit 9 is provided between the second gas shearing unit 5 and the third gas shearing unit 14. In addition, as a position of the 1st magnetic active water preparation part 9, it is not limited to this.

  The said 1st magnetic active water preparation part 9 should just be a thing which can apply a magnetic field to the nanobubble containing water manufactured in the 2nd gas shear part 5, and the specific structure is not specifically limited. For example, as shown in FIG. 1, the first magnetic active water preparation unit 9 can be provided so as to be sandwiched between the flange 6 and the flange 12. As shown in FIG. 1, the flange 6 is provided at the end of the pipe 50, and the flange 12 is provided at the end of the pipe 13. In addition, a flange 6 is provided at one end of the first magnetic active water preparation unit 9 and a flange 12 is provided at the other end. And the said 1st magnetic active water preparation part 9 can be provided between the said flange 6 and the flange 12 by fixing the said flanges 6 and the said flanges 12 with a volt | bolt etc.

  The said 1st magnetic active water preparation part 9 has the flow path 26 for allowing nanobubble containing water to pass through. And at least a part of the flow path 26 is sandwiched between a region functioning as the S pole of the magnet and a region functioning as the N pole of the magnet, whereby the nanobubble-containing water passing through the flow path 26 It becomes possible to apply a magnetic field.

  The shape of the cross section of the flow path 26 is not particularly limited and can be set as appropriate. The cross-sectional shape of the channel 26 is preferably, for example, one having at least one pair of opposed surfaces (for example, a square or a rectangle). In addition, when the shape of the cross section of the said flow path 26 is square or a rectangle, it is preferable that the three-dimensional shape of the said flow path 26 becomes a substantially flat shape.

  As an example, FIG. 13 shows a cross-sectional view of the first magnetic active water preparation unit 9 having a flow path 26 having a rectangular cross section. As shown in FIG. 13, the flow path 26 has a first surface 60 and a second surface 61 that face each other. The S pole 10 of the magnet is disposed on the first surface 60 side, and the N pole 16 of the magnet is disposed on the second surface 61 side. Then, a magnetic field is formed between the S pole 10 and the N pole 16, and the nanobubble-containing water passes through the magnetic field. In other words, as shown in FIG. 1, the bubble-containing water passes through the magnetic field lines 11 formed between the S pole 10 and the N pole 16. And magnetic activity is provided to nanobubble content water by passing through the inside of a magnetic field.

  That is, when the liquid passes through the magnetic field lines 11, a weak current is generated. Then, the bonds between the water molecules are broken by the action of a weak current, and as a result, the clusters (clusters of molecules) are subdivided. Since the water in which the clusters are subdivided has a high effect of absorbing oxygen in the gaps between the clusters, a large amount of oxygen is absorbed from the outside air and the dissolved oxygen concentration becomes high. At the same time, radicals can be generated in the liquid by the action of a weak current. As a result, if magnetic activity is imparted to the liquid, it becomes possible to generate active oxygen in the liquid. Therefore, the nanobubble-containing water having magnetic activity can have both the oxidation ability of free radicals derived from nanobubbles and the oxidation ability derived from the active oxygen, and the strong oxidation ability makes it difficult to decompose. Organic matter can also be decomposed.

  The distance between the first surface 60 and the second surface 61 is not particularly limited, and can be set as appropriate. For example, the distance between the first surface 60 and the second surface 61 is preferably 30 mm or less. According to the said structure, the activity as magnetic active water can be efficiently provided with respect to nanobubble containing water.

  Further, the magnetic flux density (residual magnetic flux density) in the flow path 26 is 350 millitesla (3500 gauss or more is preferable, and 450 millitesla or more is more preferable.

  Further, the number of the S poles 10 of the magnet disposed on the first surface 60 side and the number of the N poles 16 of the magnet disposed on the second surface 61 side are not particularly limited and should be set as appropriate. Can do. For example, as shown in FIG. 1, three S poles 10 and three N poles 16 can be arranged, but the present invention is not limited to this.

  In the nanobubble-containing magnetic active water production apparatus according to the present embodiment, the nanobubble-containing magnetic active water produced by the first magnetic active water production unit 9 is introduced into the third gas shearing unit 14 via the pipe 13. As described above, in the third gas shearing portion 14, the nanobubbles are further sheared. As a result, the size of the nanobubbles in the nanobubble-containing magnetic active water is reduced, and the amount of contained nanobubbles is increased. In addition, since the detail of the 3rd gas shearing part 14 was already demonstrated, the description is abbreviate | omitted here.

  In the nanobubble-containing magnetic active water production apparatus of the present embodiment, the nanobubble-containing magnetic active water processed by the third gas shearing unit 14 is discharged into the tank 1 as indicated by an arrow 15. The discharge location of the nanobubble-containing magnetic active water is not limited to the tank 1. For example, a tank different from the tank 1 can be prepared and discharged into the other tank.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. Configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiment 1 are given the same reference numerals and explanation thereof is omitted.

  The nanobubble-containing magnetic active water production apparatus of the present embodiment is different from the first embodiment in that the second gas shearing part 5 is provided downstream of the first magnetic active water production part 9.

  Therefore, in the nanobubble-containing magnetic active water producing apparatus of the present embodiment, the microbubble-containing water produced by the first gas shearing unit 4 is first introduced into the first pipe diameter adjusting unit 34 and made into a phase flow. Thereafter, the microbubble-containing water is introduced into the first magnetic active water preparation unit 9, and magnetic activity is imparted to the microbubble-containing water. And the microbubble containing water to which magnetic activity was provided is introduce | transduced into the 2nd gas shearing part 5, and then the 3rd gas shearing part 14, and nanobubble containing hydromagnetic active water is manufactured. Then, the nanobubble-containing magnetic active water is discharged into the tank 1.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIG. Configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiment 1 are given the same reference numerals and explanation thereof is omitted.

  In the nanobubble-containing magnetic active water producing apparatus according to the present embodiment, the second gas shearing part 5 is provided downstream of the first magnetic active water producing part 9, and the second pipe diameter adjusting part 37 and the second magnetic active water are provided. The manufacturing unit 19 is different from the first embodiment in that the manufacturing unit 19 is provided upstream of the first gas shearing unit 4.

  In the nanobubble-containing magnetic active water producing apparatus of the present embodiment, the liquid in the tank 1 is introduced into the second pipe diameter adjusting unit 37 and then the second magnetic active water producing unit 19 through the pipe 2 and then the first gas. It is introduced into the shearing part 4.

  The second pipe diameter adjusting section 37 can be formed in the same manner as the first pipe diameter adjusting section 34 described above. The second pipe diameter adjusting unit 37 can convert the liquid taken in a turbulent state into a phase flow, and then introduce the liquid into the second magnetic active water preparation unit 19.

  Moreover, the said 2nd magnetic active water preparation part 19 can be fundamentally formed similarly to the 1st magnetic active water preparation part 9 mentioned above. Specifically, as shown in FIG. 3, the second magnetic active water preparation unit 19 is provided between the flange 23 and the flange 25. And the said 2nd magnetic active water preparation part 19 is provided with the flow path 24, and the S pole 20 and the N pole 21 of one magnet are arrange | positioned so that the said flow path 24 may be pinched | interposed. The numbers of the S pole 20 and the N pole 21 of the magnet are not particularly limited. Then, the liquid passes through the lines of magnetic force 22 formed between the S pole 20 and the N pole 21. The flow path 24 may be configured similarly to the flow path 26 described above.

  When the liquid passes through the magnetic field lines 22, a weak current is generated. Then, the bonds between the water molecules are broken by the action of a weak current, and as a result, the clusters (clusters of molecules) are subdivided. Since the liquid in which the clusters are subdivided has a high action of absorbing oxygen between the clusters, the dissolved oxygen concentration is increased by absorbing a large amount of oxygen from the outside air. At the same time, radicals can be generated in the liquid by the action of a weak current. As a result, if magnetic activity is imparted to the liquid, it becomes possible to generate active oxygen in the liquid. That is, in the nanobubble-containing magnetic active water production apparatus of the present embodiment, the nanobubble-containing final product is obtained by preliminarily imparting magnetic activity to a liquid that is one of materials for producing microbubble-containing water. The oxidation ability of the magnetically active water can be further increased.

  In addition, since the downstream of the said 2nd magnetic active water preparation part 19 was demonstrated in Embodiment 2, the description is abbreviate | omitted here.

  As a result of examining the oxidation ability of the nanobubble-containing magnetic active water using the decolorization action of the colored liquid as an index, the apparatus described in the third embodiment is more effective than the nanobubble-containing magnetic active water prepared in the apparatus described in the first embodiment. The produced nanobubble-containing magnetic active water had higher oxidation ability (see Examples).

[Embodiment 4]
The following will describe another embodiment of the present invention with reference to FIG. Configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of Embodiment 1 are given the same reference numerals and explanation thereof is omitted.

  The nanobubble-containing magnetic active water production apparatus according to the present embodiment is different from the first embodiment in that the container 48 is provided in the tank 1 and the activated carbon 18 is filled in the container 48.

  Therefore, in the nanobubble-containing magnetic active water producing apparatus of the present embodiment, the organic matter in the liquid can be decomposed by oxidizing the liquid, and the organic matter or the like is physically adsorbed on the activated carbon 18, Organic substances and the like can be removed from the liquid. In addition, since the said accommodating part 48 is provided in the tank 1, when nanobubble containing magnetic active water is discharged in the tank 1, it is from both the liquid which is a raw material, and the nanobubble containing magnetic active water which is a final product. Organic substances and the like can be removed.

The oxidation-reduction potentiometer 29 measures the oxidation-reduction potential of the mixture of the liquid in the tank 1 and the magnetic active water containing nanobubbles. From this measurement, it can be determined whether the oxidation-reduction potential of the mixture is larger or smaller than the desired oxidation-reduction potential. Note that the oxidation-reduction potential is an index indicating whether the substance is in a state where it is likely to oxidize other substances or is easily reduced. That is, when the value of the oxidation-reduction potential is large on the plus side, it indicates that the oxidizing power is strong, and when it is large on the minus side, it indicates that the reducing power is strong.
In addition, it does not specifically limit as a specific structure of the said oxidation-reduction potentiometer 29, A well-known oxidation-reduction potentiometer can be used suitably.

The oxidation-reduction potential controller 31 is previously input with the value of the oxidation-reduction potential that the nanobubble-containing magnetic active water to be produced should have, and the value is compared with the actually measured value. And the said oxidation-reduction potential regulator 31 judges whether the quantity of the nano bubble in nano bubble containing magnetic active water should be increased based on the said comparison result.

  The determination made by the upper oxidation-reduction potential controller 31 is transmitted to the sequencer 32, and the sequencer 32 controls the opening / closing operation of the electric needle valve 8 or the output of the gas-liquid mixing circulation pump 3 based on the above determination. To do. That is, when the measured redox potential value of the nanobubble-containing magnetic active water is larger than the desired value, the nanobubble-containing magnetic active water is closed by closing the electric needle valve 8 or lowering the output of the gas-liquid mixing circulation pump 3. Reduce the amount of nanobubbles inside. On the other hand, when the measured redox potential of the nanobubble-containing magnetic active water is smaller than the desired value, the nanobubble-containing magnetic active water is opened by opening the electric needle valve 8 or increasing the output of the gas-liquid mixing circulation pump 3. Increase the amount of nanobubbles inside. Thereby, the redox potential of the nanobubble-containing magnetic active water can be set to a desired value.

[1. Magnetic active water production equipment containing nanobubbles]
Based on FIG. 1, a nanobubble-containing magnetic active water production apparatus was produced. The capacity of the tank 1 was about 1 m ³ . Moreover, as the nano bubble generator 47, the one having the 3.7 kw gas-liquid mixing circulation pump 3 (HYK type manufactured by Kyowa Kikai Co., Ltd.) was used. Moreover, as the 1st magnetic active water preparation part 9, the dimension was 800 mm in total length, the cross-sectional width of 160 mm, and the cross-sectional vertical width of 310 mm (BK type | mold by BCE OH Co., Ltd.).

  After putting 800 liters of water into the tank 1, the nanobubble generator 47 was operated for 12 minutes, and the diameter and amount of the nanobubbles were measured with a measuring instrument manufactured by Beckman Coulter, Inc. As a center, it was confirmed that the nanobubbles were substantially normally distributed.

  Moreover, when the oxidation-reduction potential derived from the magnetic activity which nanobubble containing magnetic active water has was measured with the ORP meter (HC type | mold by Toa DKK Corporation), it was 300 mv of plus.

[2. (Relation between gas volume and bubble size)
Using the nanobubble-containing magnetic active water production apparatus described above, the relationship between the amount of gas (air) supplied to the first gas shearing portion 4 and the size of the bubbles produced at that time was examined. The amount of gas supplied to the microbubble generator 4 is 0.6 L / min, 0.75 L / min, 1.2 L / min, or 1.5 L / min, and the diameter of the bubble produced under each condition And the amount were measured with a measuring instrument manufactured by Beckman Coulter, Inc. The results are shown in Table 1.

  As is clear from Table 1, it was revealed that nanobubbles can be efficiently produced when the gas supplied to the first gas shearing portion 4 is 1.2 L / min or less. On the other hand, if the gas supplied to the first gas shearing part 4 is more than 1.2 L / min, it was revealed that microbubbles are produced instead of nanobubbles.

[3. (Air intake start time to gas-liquid mixing circulation pump)
Using the nanobubble-containing magnetic active water production apparatus described above, the relationship between the start time of air intake into the gas-liquid mixing circulation pump 3 and the vibration at a location 1 m away from the gas-liquid mixing circulation pump 3 was examined. The results are shown in Table 2.

  As is clear from Table 2, it was found that if air was taken into the gas-liquid mixing and circulating pump 3 after 60 seconds from the start of operation of the gas-liquid mixing and circulating pump 3, the vibration was extremely low. In a typical measuring instrument, vibrations of 45 dB or less cannot be measured because the value is too low.

  If vibration is suppressed under the above conditions, nanobubbles can be produced without imposing a burden on the impeller of the pump and without damaging the impeller.

[4. The thickness of the partition wall of the first gas shearing part 4]
In the nanobubble-containing magnetic active water manufacturing apparatus described above, the thickness of the partition wall of the first gas shearing part 4 was changed to various thicknesses, and vibrations at a location 1 m away from the gas-liquid mixing and circulation pump 3 were measured at that time. The results are shown in Table 3.

  As is apparent from Table 3, it was found that the vibration was large when the thickness of the first gas shearing portion 4 was 5 mm or less. That is, if the thickness of the first gas shearing part 4 is 5 mm or less, the kinetic energy of the mixture of the liquid and gas swirling inside the first gas shearing part 4 propagates outside as vibration and is lost. It became clear that

  On the other hand, when the thickness of the first gas shearing part 4 is 6 mm or more, it has been clarified that the vibration is small. In other words, if the thickness of the first gas shearing part 4 is 6 mm or more, the kinetic energy of the mixture of the liquid and gas swirling inside the first gas shearing part 4 propagates outside as vibration and is lost. It became clear that it would never happen.

Introduced. And the water processed by both the said nano bubble containing magnetic active water manufacturing apparatus 17 and the organic fluorine compound containing wastewater treatment equipment 41 was collected in said 1), 2), and 6), and the quality of the said treated water was examined.

  Specifically, chromaticity, chemical oxygen demand, and organic fluorine compound concentration were measured as the water quality indicators. Note that perfluorooctanoic acid (PFOA) was used as the organic fluorine compound. Further, a liquid chromatograph-tandem mass spectrometer (LC-MS / MS method) was used for the measurement of the organic fluorine compound concentration.
