Description

  The present invention relates to a processing apparatus and a processing method for processing various liquids using nanobubble-containing magnetic active water.

  Dioxins, organic fluorine compounds (for example, perfluorooctasulfonic acid (PFOS) or perfluorooctanoic acid (PFOA), etc.) 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, development of various processing apparatuses and processing methods for processing (for example, recovery and decomposition) of the organic fluorine compound after being used as an industrial material has been advanced.

  As described above, since the organic fluorine compound is a chemically stable substance, it is difficult to efficiently decompose it by microorganisms. Therefore, conventionally, when treating an organic fluorine compound, a method of incinerating waste water containing the organic fluorine compound at a temperature of 1000 ° C. or higher has been used.

  Conventionally, a method of recovering an organic fluorine compound contained in waste water or the like by adsorbing the organic fluorine compound on activated carbon has been used.

  By the way, it has been conventionally known that bubbles having a small diameter have various actions, and research on techniques for producing such bubbles and their effects are currently being advanced. 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 when generated. 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 ozone gas produced by an ozone generator and waste liquid using a pressure pump. And when the said microbubble reacts with the organic substance in a waste liquid, the organic substance in a waste liquid is oxidized and decomposed | disassembled.

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

  For example, the incineration method has a problem that a large amount of fuel is required when the amount of liquid to be processed is large. Moreover, since the said method discharge | releases a large amount of carbon dioxide, it also has the problem of causing global warming.

  In addition, the method of adsorbing organic fluorine compounds on activated carbon (for example, activated carbon adsorption tower) generally has a large load of organic matter on the activated carbon, causing the phenomenon of activated carbon breakthrough, and the adsorption capacity of activated carbon decreases rapidly. Have the problem of In addition, since this method is not basically a method for decomposing an organic fluorine compound, if a large amount of the organic fluorine compound is adsorbed on the surface of the activated carbon, it is necessary to exchange the activated carbon. Therefore, this method has a problem that it requires a cumbersome operation of exchanging activated carbon and enormous costs for exchanging activated carbon.

  Further, the conventional processing apparatus and processing method as described above have low processing capability, and are not suitable for processing a large amount of liquid. Therefore, there is a problem that an organic fluorine compound contained in a small amount in a large amount of liquid such as tap water or groundwater cannot be treated.

  The method using bubbles can decompose various organic substances, but cannot efficiently decompose chemically stable substances such as organic fluorine compounds. Therefore, there is a problem that a large amount of the organic fluorine compound cannot be treated.

  Moreover, since the organic substance etc. which were adsorbed by activated carbon can be decomposed | disassembled by the said oxidation action, there exists an effect that the fall of the adsorption capacity of activated carbon can be prevented.

  In addition, since the microorganisms can be activated by the magnetically active water and the nanobubbles, the organic substance in the liquid can be efficiently decomposed by the microorganisms.

[Embodiment 1]
An embodiment of the present invention will be described with reference to FIG. 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. In addition, the term “magnetic activity” as used herein refers to the activity of a liquid or gas due to the action of magnetic lines of force.

  The processing apparatus of the present embodiment includes a liquid storage tank 18 and a processing unit 85. Each configuration will be described below.

[1. (Liquid storage tank)
Below, the liquid storage tank 18 is demonstrated.

  In the liquid storage tank 18, the liquid processed by the processing apparatus of the present embodiment is temporarily stored.

  The kind of the liquid stored in the liquid storage tank 18 is not particularly limited, and the liquid to be processed may be appropriately selected.

  For example, as the liquid, fresh water (for example, river water, pond water (for example, agricultural water, aquaculture water, farming water, etc.), well water, etc.), seawater, and the like can be used. . According to the said structure, since the organic compound etc. which are contained in fresh water or seawater can be removed, fresh water or seawater after removal is used for various uses (for example, drinking water, industrial water, etc.). it can.

  Moreover, various wastewaters (for example, factory wastewater, industrial wastewater, domestic wastewater, sewage, bathtub water, etc.) can be used as the liquid. According to the above configuration, since organic compounds and the like in various wastewaters can be efficiently decomposed, it becomes possible to use the wastewater after being decomposed for various purposes or to release it to nature.

  Further, the liquid may contain an organic fluorine compound (for example, perfluorooctasulfonic acid (PFOS), perfluorooctanoic acid (PFOA), etc.). Since the treatment apparatus of the present embodiment has a high oxidative decomposition ability, even a chemically stable hardly decomposable compound can be efficiently decomposed.

  The liquid stored in the liquid storage tank 18 is supplied to the processing unit 85 via the pipe 21 by the pump 19. At this time, the amount of liquid supplied to the processing unit 85 is adjusted by the valve 20 provided in the pipe 21.

  For example, when waste water is introduced into the liquid storage tank 18 (see FIG. 3), various types of waste water can be appropriately treated by the treatment apparatus of the present embodiment. In other words, wastewater includes wastewater containing components that are difficult to decompose microbiologically and wastewater containing organic substances at a high concentration. However, if the processing apparatus of this Embodiment is used, while being able to provide magnetic activity with respect to wastewater, a nanobubble can be contained. As a result, the organic substance can be oxidatively decomposed by the magnetic activity and the oxidizing action derived from the nanobubbles, and the microorganism can be activated by the nanobubble-containing magnetic active water, and the organic substance can also be decomposed by the microorganism. As a result, wastewater that has been difficult to treat can be treated.

  For example, when river water is introduced into the liquid storage tank 18 (see FIG. 4), the river water can be appropriately processed by the processing apparatus of the present embodiment. For example, highly treated treated water can be obtained by decomposing trace amounts of trihalomethane, environmental hormones, organic fluorine compounds and the like contained in river water, or by adsorbing the substance onto activated carbon. The treated water thus obtained can be used not only as clean water but also as pre-treated water for producing ultrapure water. Moreover, it can also be used as a water production apparatus in an area where the water quality of the river is poor.

  Further, for example, when the water in the pond is introduced into the liquid storage tank 18 (see FIG. 5), the water in the pond can be appropriately processed by the processing apparatus of the present embodiment. For example, it is possible to obtain highly treated treated water by decomposing organic substances, ammoniacal nitrogen, trihalomethane, environmental hormones, organic fluorine compounds, etc. contained in pond water or by adsorbing the substances onto activated carbon. . The treated water thus obtained can be used not only as clean water but also as pre-treated water for producing ultrapure water. In addition, it can be used as a water production apparatus in an area where the water quality of the pond is poor.

  Further, for example, when organic fluorine compound-containing water is introduced into the liquid storage tank 18 (see FIG. 6), the organic fluorine compound-containing water can be appropriately treated by the treatment apparatus of the present embodiment. That is, the organic fluorine compound can be efficiently decomposed by the processing apparatus of this embodiment.

  Further, for example, when sewage is introduced into the liquid storage tank 18 (see FIG. 7), the sewage can be appropriately treated by the treatment apparatus of the present embodiment. That is, the treatment apparatus of the present embodiment can not only improve water quality but also remove colored components. In particular, in the case of the processing apparatus of the present embodiment, foaming does not occur in the microorganism tank 46 described later even when detergent is mixed in sewage. As a result, it is possible to prevent the processing effect in the microorganism tank 46 from being lowered. Furthermore, since it does not foam in the microorganism tank 46, the property of microorganisms can be improved. As a result, the amount of permeated water in the separation unit 55 increases, so that the processing capacity of the entire processing apparatus can be improved.

  Further, for example, when domestic wastewater is introduced into the liquid storage tank 18 (see FIG. 8), the domestic wastewater can be appropriately treated by the treatment apparatus of the present embodiment. In this case, the foaming of the detergent can be prevented as in the case of the sewage described above.

[2. Processing section
The processing unit 85 will be described below.

  In the said process part 85, while providing magnetic activity with respect to the said liquid, a nano bubble is generated in the said liquid. And the organic compound in a liquid is oxidatively decomposed | disassembled by both the oxidation capability derived from magnetic activity, and the oxidation capability derived from nanobubble. Moreover, in the said process part, while performing the microorganisms process with respect to the said liquid, the adsorption process by activated carbon is performed. As a result, the organic compound in the liquid is decomposed by the activated microorganisms, and the organic compound remaining in the liquid is adsorbed on the activated carbon. As a result, the organic compound in the liquid is efficiently removed. Note that the organic compound adsorbed on the activated carbon is constantly subjected to the magnetic activity and the oxidizing action derived from nanobubbles, so that the organic compound is also oxidatively decomposed. As a result, since the surface of the activated carbon is constantly regenerated, the frequency of replacing the activated carbon can be reduced.

  The said process part 85 is the 1st magnetic active water preparation part 38 (1st activation means), the front tank 1 (magnetic active water preparation means), the 1st nanobubble generation part 17 (1st nanobubble preparation means), and the microorganism tank 46 (mixing) Means), a second nanobubble generating part 78 (second nanobubble producing means), and an activated carbon tank 81. Each configuration will be described below.

[2-1. (Front tank)
First, the front tank 1 will be described.

  The front tank 1 includes a first tank 22 and a second tank 27, and the first tank 22 and the second tank 27 are connected to each other. The liquid stored in the liquid storage tank 18 described above is discharged into the first tank 22. In the first tank 22, an air diffuser 24 connected to the first magnetic active water preparation unit 38 via a pipe 23 is provided. Then, the gas 25 (first gas) is discharged from the diffuser tube 24, and the gas 25 and the liquid raw material forming the water flow 43 are stirred in the first tank 22.

  As described above, the gas 25 and the liquid are stirred in the first tank 22. As will be described later, the gas 25 is a gas imparted with magnetic activity. Therefore, by stirring the gas 25 and the liquid, a liquid to which magnetic activity is imparted, that is, magnetically active water can be produced. At this time, if a relatively large impurity is mixed in the liquid, the gas 25 adheres to the surface of the impurity to form a complex. Since the buoyancy derived from the gas 25 attached to the surface acts on the composite, the composite accumulates in the vicinity of the surface of the liquid stored in the first tank 22. As a result, relatively large impurities can be removed from the liquid present in the vicinity of the bottom of the first tank 22.

  At this time, the first tank 22 and the second tank 27 are preferably connected to each other through the vicinity of the bottom of the first tank 22. According to the above configuration, the liquid from which relatively large impurities are removed can be selectively taken into the second tank 27. And since a comparatively big impurity can be removed previously, the quantity of the substance which should be processed in a next process can be reduced.

[2-2: First magnetic active water preparation unit]
Next, the first magnetic active water preparation unit 38 will be described.

  The said 1st magnetic active water preparation part 38 is the structure for providing magnetic activity with respect to the gas 25 (1st gas). And as above-mentioned, magnetic activity is provided and magnetic activity can be provided to the said liquid by stirring the gas 25 and liquid.

  In the processing apparatus of this Embodiment, gas is supplied to the 1st magnetic active water preparation part 38 via the piping 95 (1st piping) by the blower 29. FIG.

  It does not specifically limit as said gas, A well-known gas can be used suitably. For example, as the gas, air, ozone gas, carbon dioxide gas, oxygen gas, nitrogen gas, or the like can be used, but the gas is not limited thereto.

  Further, the pipe 95 is provided with a first pipe diameter adjusting unit 31 (first pipe diameter adjusting means) that can change the size of at least a part of the inner cross section of the pipe 95. preferable. According to the said structure, while being able to convert the gas which is a turbulent flow into a phase flow, the flow velocity of the gas introduce | transduced into the 1st magnetic active water preparation part 38 can be adjusted. And thereby, a magnetic field can be equally applied with respect to gas in the 1st magnetic active water preparation part mentioned later.

  In addition, it is preferable that the flow velocity of the gas introduced into the 1st magnetic active water preparation part 38 is 10 m / sec or more. According to the said structure, the influence of a magnetic field can be efficiently performed with respect to gas.

  The first pipe diameter adjusting unit 31 is not particularly limited as long as it can change the size of at least a part of the lumen cross section of the pipe 95.

  For example, as shown in FIGS. 12A and 12B, the first pipe diameter adjusting portion 31 can be formed by a pipe having a cylindrical shape. As shown in FIG. 12A, a flange 30 and a flange 32 are provided at each end of the pipe 95. Further, a flange 30 and a flange 32 are also provided at each end of the first pipe diameter adjusting unit 31. The flange 30 and the flange 32 are provided with bolt holes 99. And as shown in FIG.12 (b), the flange 30 with which the piping 95 was equipped with the flange 30 and the flange 30 with which the 1st piping diameter adjustment part 31 was equipped, and piping by attaching / detaching a volt | bolt to the said bolt hole 99. The flange 32 provided to 95 and the flange 32 provided to the first pipe diameter adjusting unit 31 can be attached and detached. Accordingly, the first pipe diameter adjusting unit 31 connected between the end portions of the pipe 95 can be exchanged. At this time, a plurality of first pipe diameter adjusting sections 31 having different cylindrical shapes, that is, cylindrical shapes having different cross-sectional diameters are prepared, and a desired first pipe diameter adjusting section 31 is selected from these. If the first pipe diameter adjusting unit 31 is connected between the ends of the pipe 95, at least a part of the lumen cross section of the pipe 95 can be changed to a desired size. In addition, according to the shape and magnitude | size of the cross section of the 1st piping diameter adjustment part 31, the shape and magnitude | size of the flange 30 and the flange 32 can be selected suitably.

  When the 1st piping diameter adjustment part 31 is formed by cylindrical piping, the length of the said 1st piping diameter adjustment part 31 in the direction through which gas flows is not specifically limited, It can set suitably. For example, the length of the first pipe diameter adjusting unit 31 is preferably 10 times or more the diameter of an opening opened in the flange 36 described later. Further, the length of the first pipe diameter adjusting unit 31 is more preferably 10 times or more the diameter of the cross section of the first pipe diameter adjusting unit 31 having a cylindrical shape.

  According to the said structure, after making the gas introduced in the 1st piping diameter adjustment part 31 into a turbulent flow into a phase flow reliably, the said gas can be discharged to the 1st magnetic active water preparation part 38 side.

  The gas converted into the phase flow by the first pipe diameter adjusting unit 31 is introduced into the first magnetic active water preparation unit 38.

  The 1st magnetic active water preparation part 38 should just be a thing which can apply a magnetic field to gas, The concrete structure is not specifically limited. For example, as shown in FIG. 1, the flange 36 is provided at the end of the pipe 95, and the flange 42 is provided at the end of the pipe 23. In addition, a flange 36 is provided at one end of the first magnetic active water preparation unit 38 and a flange 42 is provided at the other end. And the said 1st magnetic active water preparation part 38 can be provided between the said flange 36 and the flange 42 by fixing the said flanges 36 and the said flanges 42 with a volt | bolt etc.

  The said 1st magnetic active water preparation part 38 has the flow path 37 (1st flow path) for allowing gas to pass through. At least a part of the flow path 37 is sandwiched between a region functioning as the S pole of the magnet and a region functioning as the N pole of the magnet, thereby applying a magnetic field to the gas passing through the flow path 37. It becomes possible to apply.

  The shape of the cross section of the flow path 37 is not particularly limited and can be set as appropriate. The cross-sectional shape of the flow path 37 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 37 is square or a rectangle, for example, it is preferable that the three-dimensional shape of the said flow path 37 becomes a substantially flat plate shape.

  As an example, FIG. 13 shows a cross-sectional view of a first magnetic active water preparation unit 38 having a flow path 37 having a rectangular cross section. As shown in FIG. 13, the flow path 37 has a surface 100 (first surface) and a surface 101 (second surface) that face each other. A magnetic south pole 40 is disposed on the surface 100 side, and a magnetic north pole 39 is disposed on the surface 101 side. A magnetic field is formed between the S pole 40 and the N pole 39, and gas passes through the magnetic field. In other words, as shown in FIG. 1, the gas passes through the lines of magnetic force 41 formed between the S pole 40 and the N pole 39. The gas is given magnetic activity by passing through the magnetic field.

  The distance between the surface 100 and the surface 101 is not particularly limited, and can be set as appropriate. For example, the distance between the surface 100 and the surface 101 is preferably 30 mm or less. According to the said structure, magnetic activity can be efficiently provided with respect to gas.

  The magnetic flux density (residual magnetic flux density) in the flow path 37 is 350 millitesla (3500 gauss or more is preferable, and 450 millitesla or more is more preferable.

  As described above, the gas imparted with magnetic activity is discharged into the first tank 22 as the gas 25 as described above, and as a result, is stirred with the liquid. And the liquid (magnetic active water) to which magnetic activity was provided by this is introduced into the 1st nanobubble generation part 17. FIG.

[2-3: First nanobubble generator]
Next, the first nanobubble generator 17 will be described.

  The first nanobubble generator 17 includes a pipe 2, a pipe 96 (second pipe), a first gas shearing section 4 having a first gas-liquid mixing circulation pump 3, a second gas shearing section 5, and a fifth gas shearing section 14. The second pipe diameter adjusting section 34 (second pipe diameter adjusting means), the second magnetic active water preparation section 9 (second activating means), the pipe 7, and the electric needle valve 8 are provided.

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

  The gas (second gas) is not particularly limited. For example, as the gas, air, ozone gas, carbon dioxide gas, oxygen gas, nitrogen gas, or the like can be used, but the gas is not limited thereto.

  The liquid is supplied into the first gas shearing section 4 by operating the first gas-liquid mixing circulation pump 3. Further, the timing of gas supply into the first gas shearing section 4 and the adjustment of the gas supply amount are adjusted by opening and closing 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 first gas-liquid mixing circulation pump 3 is started to introduce the liquid into the first gas shearing section 4 and to stir the liquid. Thereafter, it is preferable to open the electric needle valve 8 after the time when the output of the first gas-liquid mixing circulation pump 3 reaches the maximum value, thereby supplying gas into the first gas shearing portion 4. In addition, after 60 seconds from the start of the operation of the first gas-liquid mixing circulation pump 3, the electric needle valve 8 is opened, whereby gas can be supplied into the first gas shearing section 4. More preferred.

  Although it is possible to open the electric needle valve 8 at the start of operation of the first gas-liquid mixing and circulation pump 3, in this case, the first gas-liquid mixing and circulation pump 3 causes a cavitation phenomenon. The gas-liquid mixing circulation pump 3 may be damaged. However, if it is the said structure, since it can prevent that the 1st gas-liquid mixing circulation pump 3 raise | generates a cavitation phenomenon, it can prevent that the 1st 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. If it is the said structure, a lot of nanobubble containing water can be produced efficiently.

  Next, a process of producing nanobubble-containing water (first nanobubble-containing water) by the first nanobubble generator 17 will be described. The nanobubble-containing water is generally manufactured 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.

[2-3-1: First gas shearing process]
In the first gas shearing step, microbubble-containing water is produced from the gas and the liquid. In other words, microbubbles made of a gas (second gas) supplied to the first gas shearing part 4 mainly through the pipe 7 are produced.

  In the first gas shearing process, in the first gas shearing section 4, the pressure of the mixture of gas and liquid is controlled hydrodynamically by using the first gas-liquid mixing circulation pump 3, and against the negative pressure section Gas 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. Fine gas bubbles can be 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 1st gas-liquid mixing circulation pump 3, It is preferable that it is a pump with a high head of 40 m or more (pressure of 4 kg / cm <2>). The first 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 1st 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 1st gas-liquid mixing circulation pump 3 is controlled by rotation control parts (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 which comprises 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 section 4 having the first 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 section 4, the first gas-liquid mixing circulation pump 3 moves the microbubble-containing water at high speed fluid motion to form a negative pressure section and control the pressure of the microbubble-containing water hydrodynamically. By doing so, 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 first gas-liquid mixing circulation pump 3 and pumping the liquid and gas while effectively self-mixing and dissolving.

  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 be formed on the internal surface of the 1st gas shear part 4, and has a concave shape, 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 96. At this time, the area of the cross section of the lumen of the pipe for supplying the liquid is preferably larger than the area of the cross section of the lumen of the pipe for discharging the water containing microbubbles. According to the said structure, since the discharge pressure of microbubble containing water can be raised, a microbubble can be generated stably.

[2-3-2: Second gas shearing step]
In the second gas shearing step, nanobubble-containing water (first nanobubble-containing water) is produced from the microbubble-containing water (first 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 other words, nanobubbles made of a gas (second gas) supplied to the first gas shearing part 4 mainly through the pipe 7 are produced.

  In addition, the 5th gas shearing part 14 can further be provided as needed. If the 5th 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 fifth gas shearing portion 14 is not particularly limited. For example, it is also possible to install downstream of the second magnetic active water preparation unit 9 described later, and it is also possible to install upstream of the second 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 fifth gas shearing section 14 by the first 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 fifth gas shearing section 14 via 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 above configuration, organic substances and the like can be oxidatively decomposed by the action of free radicals.

  Moreover, it is preferable that the 2nd gas shearing part 5 and the 5th 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 5th 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 5th 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 part 5 and the fifth gas shearing part 14 is preferably an elliptical shape, and most preferably a true circle. According to the said structure, since resistance (friction) of the internal surface of the 2nd gas shear part 5 and the 5th gas shear part 14 is small, while being able to rotate microbubble containing water at high speed, microbubble containing water is efficient It can shear well and, as a result, many nanobubbles can be generated.

  Moreover, it is preferable that the inner surface of the 2nd gas shearing part 5 and the 5th gas shearing part 14 has a hole. The diameter of the opening of the 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 fifth 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 5 and the 3rd gas shearing part 14 is controllable. As a result, nanobubbles can be generated stably by the second gas shearing part 5 and the fifth gas shearing part 14.

  In addition, as a concrete structure of the 1st gas-liquid mixing circulation pump 3, the 1st gas shearing part 4, the 2nd gas shearing part 5, and the 5th gas shearing part 14 mentioned above, it is possible to use a commercially available thing. is there. Although it does not specifically limit as each structure, For example, it is possible to use the Bavidas HYK type | mold made by Kyowa machine company.

  Next, the second 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 second pipe diameter adjusting unit 34.

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

  In addition, it is preferable that the flow rate of the nanobubble containing water introduced into the 2nd magnetic active water preparation part 9 is 2 m / sec or more. According to the said structure, it can influence the magnetic field efficiently with respect to nanobubble containing water.

  Below, the specific structure of the 2nd piping diameter adjustment part 34 is demonstrated.

  In the processing apparatus of the present embodiment, a second pipe diameter adjusting unit 34 is provided in a pipe 96 (second pipe) that connects the second gas shearing unit 5 and the second magnetic active water producing unit 9.

  The said 2nd piping diameter adjustment part 34 should just be a thing which can change the magnitude | size of the at least one lumen cross section of the piping 96, and the specific structure is not specifically limited.

  For example, as shown in FIGS. 12A and 12B, the second pipe diameter adjusting portion 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 96. A flange 33 and a flange 35 are also provided at each end of the second pipe diameter adjusting portion 34. The flange 33 and the flange 35 are provided with bolt holes 99. And as shown in FIG.12 (b), the flange 33 provided in the piping 96 and the flanges 33 provided in the 2nd piping diameter adjustment part 34, and piping are attached by attaching / detaching a volt | bolt to the said bolt hole 99. The flange 35 provided in 96 and the flange 35 provided in the second pipe diameter adjusting unit 34 can be attached and detached. Accordingly, the second pipe diameter adjusting unit 34 connected between the end portions of the pipe 96 can be exchanged. At this time, a plurality of second pipe diameter adjusting parts 34 having different cylindrical shapes, that is, cylindrical shapes having different cross-sectional diameters are prepared, and a desired second pipe diameter adjusting part 34 is selected from these. If the second pipe diameter adjusting section 34 is connected between the ends of the pipe 96, the lumen cross section of at least a part of the pipe 96 can be changed to a desired size.

  When the 2nd piping diameter adjustment part 34 is formed by cylindrical piping, the length of the said 2nd 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 second pipe diameter adjusting portion 34 is preferably 10 times or more the diameter of an opening opened in the flange 6 described later. The length of the second pipe diameter adjusting section 34 is more preferably 10 times or more the diameter of the cross section of the second pipe diameter adjusting section 34 having a cylindrical shape.

  According to the above configuration, after the nanobubble-containing water introduced into the second pipe diameter adjusting unit 34 as a turbulent flow is reliably converted into a phase flow, the nanobubble-containing water is discharged to the second magnetic active water preparation unit 9 side. be able to.

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

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

  In the treatment apparatus of the present embodiment, the second magnetic active water preparation 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. In other words, the magnetic activity of nanobubble-containing water produced using magnetically active water can be further enhanced.

  Below, the specific structure of the 2nd magnetic active water preparation part 9 is demonstrated.

  In the processing apparatus of the present embodiment, the second magnetic active water preparation unit 9 is provided between the second gas shearing unit 5 and the fifth gas shearing unit 14. In addition, as a position of the 2nd magnetic active water preparation part 9, it is not limited to this. For example, it is possible to provide the second magnetic active water preparation unit 9 upstream of the second gas shearing unit 5 and the fifth gas shearing unit 14. More specifically, for example, the second gas shearing part 5 can be provided downstream of the second magnetic active water preparation part 9 and the fifth gas shearing part 14 can be provided further downstream of the second gas shearing part. It is.

  The said 2nd 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 shearing part 5, The specific structure is not specifically limited. For example, as shown in FIG. 1, the second 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 connected to the end of the pipe 96, and the flange 12 is connected to the end of the pipe 13. And the said 2nd magnetic active water preparation part 9 may be provided between the said flange 6 and the flange 12. FIG.

  The said 2nd magnetic active water preparation part 9 has the flow path 26 (2nd flow path) for allowing nanobubble content 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 second magnetic active water preparation unit 9 having a flow path 26 having a rectangular cross-sectional shape. As shown in the figure, the flow path 26 has a surface 102 (third surface) and a surface 103 (fourth surface) that face each other. A magnet south pole 10 is disposed on the surface 102 side, and a magnet north pole 16 is disposed on the surface 103 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 the further magnetic activity is provided to nanobubble containing 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 surface 102 and the surface 103 is not particularly limited, and can be set as appropriate. For example, the distance between the surface 102 and the surface 103 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 south poles 10 of the magnet disposed on the surface 102 side and the number of the north poles 16 of the magnet disposed on the surface 103 side are not particularly limited, and can be set as appropriate. 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 addition, the said 2nd magnetic active water preparation part 9 and the said 1st magnetic active water preparation part 38 can use the same structure. More specifically, as the second magnetic active water preparation unit 9, for example, a BK type manufactured by BCE, Inc. can be used.

  In the processing apparatus of the present embodiment, the nanobubble-containing magnetic active water produced by the second magnetic active water production unit 9 is further introduced into the fifth gas shearing unit 14 via the pipe 13. As described above, the nanobubbles are further sheared in the fifth gas shearing section 14. As a result, the size of nanobubbles in the magnetic active water containing nanobubbles can be further reduced, and the amount of contained nanobubbles can be increased. In addition, since the detail of the 5th gas shearing part 14 was already demonstrated, the description is abbreviate | omitted here.

  In the processing apparatus of the present embodiment, the nanobubble-containing magnetic active water processed by the fifth gas shearing unit 14 is discharged into the second tank 27 as indicated by the arrow 15. The discharge location of the nanobubble-containing magnetic active water is not limited to the second tank 27. For example, a tank different from the second tank 27 can be prepared and discharged into the other tank.

  The nanobubble-containing magnetic active water produced as described above (the first nanobubble-containing magnetic active water) is then supplied to the microorganism tank 46 via the pipe 28. Hereinafter, the microorganism tank 46 will be described.

[2-4: Microbial tank]
In the microorganism tank 46, the microorganism and the nanobubble-containing magnetic active water are mixed. And the organic substance etc. which remain | survive in nanobubble containing magnetic active water are decomposed | disassembled by the microorganisms activated by the physiological effect which nanobubble containing magnetic active water has.

  The microorganism tank 46 includes a first microorganism tank 47, a second microorganism tank 48, a third microorganism tank 49, and a separation tank 50.

  Although the processing apparatus of this Embodiment is provided with three microorganism tanks and one separation layer, the number of each tank is not limited and can be suitably set according to the objective.

  Further, a diffuser tube 52 (for supplying a gas for stirring the liquid inside each tank to each of the first microorganism tank 47, the second microorganism tank 48, the third microorganism tank 49, and the separation tank 50). 1st gas discharge means) is provided. The gas discharged from the diffuser tube 52 is not particularly limited. For example, it is possible to connect the diffuser tube 52 to the first magnetic active water preparation unit 38 via the pipe 23. According to the said structure, the gas with which the magnetic field was applied with respect to the liquid in the said 1st microorganism tank 47, the 2nd microorganism tank 48, the 3rd microorganism tank 49, and the separation tank 50 can be supplied. As a result, by imparting magnetic activity to the liquid in the first microorganism tank 47, the second microorganism tank 48, the third microorganism tank 49, and the separation tank 50, the microorganisms in each tank can be activated. As a result, organic substances can be processed more efficiently. Note that the amount of gas supplied to each tank can be adjusted by a valve 51 provided in the pipe 23.

  The position of the diffuser tube 52 in the first microbial tank 47, the second microbial tank 48, the third microbial tank 49, and the separation tank 50 is not particularly limited. For example, half of the water depth of the liquid stored in each tank It is preferable to be provided on the upper side. According to the said structure, while being able to supply gas with respect to the liquid which exists in the upper part in each tank, the liquid which exists in the upper part in each tank can be stirred efficiently. That is, the upper half of the liquid in each tank can be an aerobic environment, and the lower half of the liquid in each tank can be an anaerobic environment. As a result, since the organic matter remaining in the liquid can be treated by both aerobic microorganisms and anaerobic microorganisms, the organic matter can be treated efficiently.

  Moreover, it is preferable that each tank of the said 1st microorganism tank 47, the 2nd microorganism tank 48, and the 3rd microorganism tank 49 is provided with the separation wall 53 for dividing the inside of each tank into an upper part and a lower part.

  The position of the separation wall 53 is not particularly limited, but is preferably provided below the position of the air diffuser 52. According to the above configuration, the environment in each tank can be more clearly divided into two with the separation wall 53 as a boundary. That is, the liquid existing above the separation wall 53 is stirred by the gas while the gas is supplied by the diffuser tube 52. As a result, the liquid existing above the separation wall 53 is maintained in an aerobic state. On the other hand, the liquid existing below the separation wall 53 is in a state of being isolated from the liquid existing above the separation wall 53 by the separation wall 53. In other words, the liquid existing in the region above the separation wall 53 cannot easily flow into the region below the separation wall 53 inside each microorganism tank. As a result, the liquid existing below the separation wall 53 is maintained in an anaerobic state. Under favorable conditions, the favorable microorganisms proliferate, and under anaerobic conditions, the effective anaerobic microorganisms proliferate. Therefore, according to the said structure, the organic substance which remains in a liquid can be processed with various microorganisms.

  The shape of the separation wall 53 is not particularly limited as long as the liquid existing above the separation wall 53 can prevent the liquid existing below the separation wall 53 from being mixed into the liquid. .

  FIG. 14A and FIG. 14B show an example of the shape of the separation wall 53. In addition, in the said drawing, in order to simplify description, the 1st microorganism tank 47 is demonstrated. FIG. 14A is a longitudinal sectional view of the first microorganism tank 47. At this time, the separation wall 53 is provided on the inner wall of the first microorganism tank 47, and the shape thereof is preferably substantially triangular, but is not limited thereto. On the other hand, FIG. 14B and FIG. 14C are cross-sectional views of the first microorganism tank 47 corresponding to the portion indicated by the dotted line in FIG. FIG. 14 (b) shows a case where the first microorganism tank 47 has a circular cross section, and FIG. 14 (c) shows a case where the first microorganism tank 47 has a substantially square cross section. .

  At this time, the separation wall 53 is formed in a shape having the opening 110. The size and shape of the opening 110 are not particularly limited. For example, when the opening 110 is circular as shown in FIG. 14B, the diameter of the opening 110 is preferably 4 m to 6 m, and the opening 110 is substantially square as shown in FIG. In this case, the length of one side of the opening 110 is preferably 4 to 6 m. In this case, the protruding length of the separation wall 53 from the wall surface of the microorganism tank 47 in the cross section is preferably 0.4 m to 0.6 m. According to the above configuration, since the separation wall 53 has a shape that sufficiently protrudes from the wall surface of the microorganism tank 47, the liquid present above the separation wall 53 exists below the separation wall 53. Can be prevented from being mixed into the liquid.

  The separation tank 50 is provided with a separation part 55 (separation means), and the separation part 55 separates microorganisms from the liquid.

  The separation unit 55 is not particularly limited as long as it can separate microorganisms from the liquid. For example, the separation unit 55 can be various separation membranes that can separate microorganisms. The separation membrane is not particularly limited, and a known separation membrane can be used as appropriate.

  The liquid from which the microorganisms have been removed by the separation unit 55 is introduced into the rear tank 59 as the first treated water via the pipe 58. The introduction of the first treated water into the rear tank 59 is performed by a pump 56, and the amount of the first treated water introduced into the rear tank 59 is adjusted by a valve 57.

  The first treated water introduced into the rear tank 59 is then introduced into the second nanobubble generator 78. Below, the 2nd nanobubble generation part 78 is demonstrated.

[2-5: Second nanobubble generator]
The second nanobubble generator 78 uses the first treated water and the gas (third gas) to have both nanobubbles made of the second gas and nanobubbles made of the third gas, and the magnetic activity is further enhanced. The produced nanobubble-containing magnetic active water (second nanobubble-containing magnetic active water) is produced.

  More specifically, first, microbubble-containing water containing microbubbles made of the third gas (second microbubble-containing water) is produced by the third gas shearing portion 63. The microbubble-containing water includes nanobubbles made of the second gas that the first treated water as the raw material already contains.

  Next, the microbubble-containing water is further sheared by the fourth gas shearing portion 64, thereby producing nanobubble-containing water (second nanobubble-containing water) including nanobubbles made of the third gas.

  As shown in FIG. 1, the second nanobubble generating unit 78 includes a pipe 61, a pipe 97 (third pipe), a third gas shearing part 63 having a second gas-liquid mixing circulation pump 62, and a fourth gas shearing part 64. A sixth gas shearing part 76, a third pipe diameter adjusting part 66 (third pipe diameter adjusting means), a third magnetic active water preparation part 70 (third activation means), a pipe 79, and an electric needle valve 80. Yes.

  The second nanobubble generator 78 can be configured in the same manner as the first nanobubble generator 17 described above. That is, the pipe 61, the pipe 97, the second gas-liquid mixing circulation pump 62, the third gas shearing part 63, the fourth gas shearing part 64, the sixth gas shearing part 76, and the third pipe diameter adjustment in the second nanobubble generating part 78. The structure of the part 66, the 3rd magnetic active water preparation part 70, the piping 79, and the electric needle valve 80 are the piping 2, the piping 96, the 1st gas-liquid mixing circulation pump 3 in the 1st nano bubble generation part 17, and the 1st, respectively. The same configuration as each configuration of the gas shearing section 4, the second gas shearing section 5, the fifth gas shearing section 14, the second pipe diameter adjusting section 34, the second magnetic active water preparation section 9, the pipe 7, and the electric needle valve 8. can do. Therefore, since these configurations in the second nanobubble generator 78 have already been described in relation to the first nanobubble generator 17, the description thereof is omitted here.

  Moreover, each structure of the flange 65, the flange 67, the flange 68, the flange 74, and the piping 75 shown in FIG. 1 is the same as the structure of the flange 33, the flange 35, the flange 6, the flange 12, and the pipe 13, respectively. can do. Therefore, since these configurations in the second nanobubble generator 78 have already been described in relation to the first nanobubble generator 17, the description thereof is omitted here.

  Further, the further detailed configuration of the third magnetic active water preparation unit 70 can be configured in the same manner as the second magnetic active water preparation unit 9 described above. That is, as shown in FIG. 1, each configuration of the flow path 69 (third flow path), the S pole 72, and the N pole 71 in the third magnetic active water preparation section 70 is the same as that in the second magnetic active water preparation section 9. The flow path 26, the S pole 10 and the N pole 16 can be configured in the same manner. A magnetic force line 73 is formed between the S pole 72 and the N pole 71. Moreover, as shown in FIG. 13, in the flow path 69, it is preferable that the surface 104 (fifth surface) and the surface 105 (sixth surface) are arranged to face each other. At this time, each configuration of the surface 104 and the surface 105 can be configured similarly to each configuration of the surface 102 and the surface 103. Therefore, since these configurations in the third magnetic active water preparation unit 70 have already been described in relation to the second magnetic active water preparation unit 9, the description thereof is omitted here.

[2-6: Activated carbon tank]
As shown in FIG. 1, the nanobubble-containing magnetic active water (second nanobubble-containing magnetic active water) produced by the second nanobubble generator 78 is discharged into the rear tank 59 as indicated by an arrow 77, and then activated carbon. It is introduced into the tank 81. The nanobubble-containing magnetic active water may be introduced into the activated carbon tank 81 without passing through the rear tank 59.

  The activated carbon tank 81 includes a diffuser tube 54 (second gas discharge means) and a storage portion 82 (active carbon storage means).

  The air diffuser 54 is connected to the first magnetic active water preparation unit 38 via the pipe 23. Therefore, since the gas to which the magnetic field is applied is discharged from the diffuser tube 54, the liquid in the activated carbon tank 81 can be agitated and magnetic activity can be imparted to the liquid in the activated carbon tank 81. As a result, it is possible to decompose the organic matter remaining in the liquid more efficiently, and to prevent the adsorption ability of the activated carbon from being lowered by decomposing the organic matter adsorbed on the surface of the activated carbon. In addition, according to the above configuration, when microorganisms are growing on the activated carbon, the microorganisms can be activated. Therefore, the microorganisms can also decompose organic substances adsorbed on the surface of the activated carbon. It becomes possible. As a result, the lifetime of the activated carbon can be extended by 3 times or more compared to the normal case.

  The accommodating part 82 should just be what can accommodate activated carbon in the state which the liquid in the activated carbon tank 81 and activated carbon can contact, and the structure is not limited. For example, the storage unit 82 preferably includes a gas storage unit 83 that stores gas (for example, air) and an activated carbon storage unit 84 that stores activated carbon 87. In this case, the activated carbon accommodating portion 84 preferably has a network structure so that the liquid and the activated carbon 87 can easily come into contact with each other.

  Activated carbon sinks in water because the specific gravity is only 1 or more. However, according to the above configuration, it is possible to prevent the housing portion 82 from sinking due to the buoyancy derived from the gas housing portion 83. As a result, the activated carbon 87 can be easily brought into contact with the liquid.

  The activated carbon 87 is not particularly limited. For example, it is possible to use coconut shell activated carbon Y-GC (registered trademark) manufactured by Atgsee Co., Ltd., but is not limited thereto.

  The liquid treated in the activated carbon tank 81 is discharged from the activated carbon tank 81 as treated water (second treated water).

The filler 88 functions as a scaffold when microorganisms grow, that is, as an immobilization carrier. That is, the microorganisms activated by the nanobubble-containing magnetic active water adhere to the filler 88 and propagate, and as a result, the concentration of microorganisms on the surface of the filler can be increased. As a result, the organic matter in the liquid can be stably decomposed. Further, by filling the filler 88, the quality of the liquid treated in the microorganism tank 46 can be stabilized even if the quality of the liquid introduced into the liquid storage tank 18 changes.

  Although it does not specifically limit as a material of the said filler 88, For example, it is preferable that it is a polyvinylidene chloride. More specifically, polyvinylidene chloride (Biocode 45 mm) manufactured by TBI Co., Ltd. can be used as the filler 88, but is not limited thereto.
