  Preferred embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic diagram illustrating the overall configuration of a pressurized multilayer micro-ozone sterilization / purification / livestock raising system according to this embodiment. This pressurized multi-layer micro-ozone sterilization / purification livestock sterilization system comprises a water intake sterilization system 2, a sterilization livestock facility 3, and a circulation purification sterilization system 4.

  The intake water purification and sterilization system 2 is a system for purifying and sterilizing the collected raw water.

  The intake water purification and sterilization system 2 includes an intake pipe 21 for taking raw water, a intake pump 22 for sending the taken raw water to the primary reaction tank 23, a first ozone generator 24 for generating ozone, and first ozone generation. The first gas-liquid stirring and mixing device 25a for mixing the ozone gas generated from the device 24 and the raw water in the primary reaction tank 23, and the gas-liquid mixing tank for mixing the raw water mixed with the micro ozone gas bubbles and the livestock water in the livestock tank 31 26, and a second gas-liquid stirring and mixing device 25b for mixing the gas-liquid mixture mixed in the gas-liquid mixing tank 26 and the ozone gas generated from the ozone generator 24. The gas-liquid mixing tank 26 is connected to the animal breeding tank 31, and is formed so that an appropriate amount of animal feeding water flows into the gas-liquid mixing tank 26. A plurality of punching plates provided at the bottom of the gas-liquid mixing tank 26 and the animal breeding tank 31 are formed in a plurality of layers, and the middle layer portion 33 which is a part of the space between the punching plates is a gas-liquid It is connected by the mixed solution injection pipe 27 and is press-fitted and diffused into the middle layer portion 33 in the animal breeding tank 31. Here, raw water means fresh water and seawater.

  The raw water passes through the intake pipe 21 and an appropriate amount of raw water is taken to the primary reaction tank 23 by the water pump 22.

  The ozone gas generated from the first ozone generator 24 is pumped to the first gas-liquid stirring and mixing device 25a. The pressurized ozone gas is mixed and stirred with the raw water by the first gas-liquid stirring and mixing device 25a to instantaneously form micro-ozone gas bubbles, and gas-liquid condensed and mixed to become gas-liquid mixed water. Microbes and harmful substances contained in the raw water taken here are sterilized and decomposed by oxidative decomposition of micro ozone gas bubbles, and the taken raw water is sterilized and purified.

  This gas-liquid mixed water is sent to the gas-liquid mixing tank 26, mixed with the animal feed water in the animal breeding tank 31, the ozone gas generated from the first ozone generator 24 is pumped to the second gas-liquid stirring and mixing apparatus 25b, and the ozone gas The gas-liquid mixed water and the animal feed water in the animal breeding tank 31 are mixed and stirred using the second gas-liquid stirring apparatus 25b, and micro ozone gas bubbles having a concentration higher than that in the state where the gas-liquid mixed water is formed in the primary reaction tank 23. Gas-liquid mixed water containing is produced. The gas-liquid mixed water containing the high-concentration micro ozone gas bubbles is press-fitted and diffused into the middle layer portion 33 of the multilayer structure of the punching plate installed at the bottom of the animal culturing tank 31.

  The sterilized animal breeding facility 3 is a facility for sterilizing, purifying and preventing eutrophication of livestock water in the animal culturing tank 31.

  FIG. 2 is a plan view inside the animal breeding tank 31. Note that only a part of the upper layer punching plate 37 in FIG. 2 is shown in order to make it easy to see the state of the air diffuser 39 and the like, and is actually connected to the entire inside of the breeding tank 31. An upper layer punching plate 37 is installed on the air diffuser 39, and the punching plate is connected to the entire inside of the animal culturing tank 31.

  In the sterilized animal breeding facility 3, a punching plate is formed in a multilayer shape on the bottom of the animal raising tank 31, and the animal raising tank 31, and a lower layer punching plate 35, an intermediate layer punching plate 36, and an upper layer punching plate 37 are formed from the bottom. In addition, there is a space between each punching plate, and a lower layer portion 32, a middle layer portion 33, and an upper layer portion 34 are formed from the bottom of the breeding tank 31. An air diffuser 39 for diffusing the air sent from the blower 38 into the animal breeding tank 31 is installed in the upper layer portion 34.

  Although the multilayer structure of the punching board which has in the bottom part in the breeding tank 31 may have any number of layers, a three-layer structure is preferable. By using a three-layer structure, it is possible to efficiently crush the circulating water containing micro-ozone gas bubbles sent from the circulation purification and sterilization system 4 to be described later, and to efficiently sterilize and purify the breeding water in the breeding tank 31. Can do.

  The lower layer part 32 is connected to the micro-ozone gas bubble-containing circulating water injection pipe 49 in the circulation purification sterilization system 4, and the micro-ozone gas bubble-containing circulating water is sent. This circulating water containing micro ozone gas bubbles passes through the lower layer punching plate 35 to promote the collapse phenomenon of the micro ozone gas bubbles.

  Here, the crushing means a phenomenon at the time of disappearance in a process in which microbubbles (microbubbles) floating in a liquid gradually shrink due to natural dissolution of the gas contained in the microbubbles and eventually disappear. It is a phenomenon discovered by earnest research. Hereinafter, the collapse of the microbubbles will be described.

As the physical properties of the microbubbles, as shown in FIG. 3, the microbubbles in distilled water have a potential of about −30 to −50 mV regardless of the bubble diameter. Therefore, for example, in water, a structure in which an anion such as OH ⁻ surrounds the surface of a bubble as shown in FIG. 4 and a cation such as H ⁺ (H ₃ O ⁺ ) is covered around the anion. Have taken.

  In addition, microbubbles have a larger specific surface area than ordinary bubbles, and the internal pressure is high because surface tension acts effectively. The theory is that the internal pressure when the microbubbles disappear can reach several thousand atmospheres.

It is known that microbubbles have a slower ascending speed than ordinary bubbles and have an excellent gas dissolving ability (natural dissolution). In other words, when normal bubbles are generated in water, they rise in the direction of the liquid surface, and the bubbles burst at the liquid level, whereas microbubbles rise at a slower rate than normal bubbles, and further have a dissolving ability. Since it is excellent, the bubble diameter gradually decreases and eventually disappears. FIG. 5 shows the measurement of the bubble diameter time until the microbubbles shrink and eventually disappear. The smaller the bubble diameter of the microbubbles, the shorter the time from when the microbubbles shrink due to natural dissolution until they disappear. In microbubbles, the maximum driving force for dissolving the gas is a self-compression effect due to the action of surface tension. The pressure rise inside the microbubble with respect to the environmental pressure is theoretically estimated by the Young-Laplace equation.
(Equation 1)
ΔP = 4σ / D
Here, ΔP is the degree of pressure increase, σ is the surface tension, and D is the bubble diameter. In the case of distilled water at room temperature, a pressure increase of about 0.3 atm with a microbubble having a diameter of 10 μm and about 3 atm at a diameter of 1 μm. Since the gas dissolves in water according to Henry's law, the gas in the self-pressurized bubbles effectively dissolves in the surrounding water.

  On the other hand, by applying physical stimuli such as discharge, ultrasonic waves, and vortex flow to the microbubbles, the speed at which the microbubbles shrink due to natural dissolution increases, so the microbubbles are adiabatically compressed and eventually the microbubbles disappear. (Crush). At this time, since the microbubbles were adiabatically compressed, when the microbubbles disappear, an extreme reaction field of ultrahigh temperature and ultrahigh pressure is formed.

As mentioned above, bubbles in water are negatively charged, but there is a saturated charge at the gas-liquid interface depending on the environmental conditions such as pH, which is observed by the zeta potential of microbubbles. can do. This charge is not caused by electrolyte ions in the water, but based on structural factors of the water itself. That is, it is due to the generation of electric charges due to the interfacial adsorption of OH ⁻ and H ⁺ resulting from the fact that the hydrogen bond network structure at the gas-liquid interface is different from the structure in the bulk. Since the formation of this structure also has the effect of suppressing the thermal molecular motion, it takes about several seconds to return to the equilibrium condition when the charge density increases or decreases.

  The reduction of bubbles due to the spontaneous dissolution of microbubbles is accompanied by a reduction in the surface area of the gas-liquid interface. As shown in FIG. 5, the surface area of the gas-liquid interface decreases as the bubbles become smaller. When the rate of decrease in the surface area at the gas-liquid interface is slow, the charge density at the gas-liquid interface changes under conditions that are substantially balanced. However, as shown in FIG. 6, when the bubble diameter becomes 10 μm or less, the dissipation of charge cannot catch up with the reduction speed, and is observed as an increase in zeta potential accompanying deviation from equilibrium. However, the decrease in the surface area of the gas-liquid interface due to natural dissolution is not so rapid, so the value of the charge density is only about several times that at equilibrium even before the disappearance.

  On the other hand, when the microbubbles are collapsed in the present invention, the rate of decrease in the surface area of the gas-liquid interface is very large, and the charge deviates from the equilibrium with almost no dissipation. As a result, a region having an extremely high charge density is formed. When a microbubble having a bubble diameter of 20 μm is crushed to 0.5 μm or less, the charge density reaches 1000 times or more that at equilibrium.

  The extremely high-density charge formed by crushing is a non-equilibrium condition, so it is extremely unstable and returns to a stable state by a phenomenon different from simple dissipation. That is, a very steep potential gradient is formed between the bubble interface in the crushing process and the surroundings, and re-equilibrium of the charge condition is realized with the movement of electrons due to discharge or the like.

This means the formation of an extremely high density energy field, which, when carried out in water, involves the formation of free radical species by the decomposition of surrounding water molecules. In addition, since the charge carriers are OH ⁻ and H ⁺ , free radical species such as .OH and .H are generated as the charge is neutralized by discharge.

Since this free radical species is very reactive, it reacts with various compounds dissolved or suspended in the solution to change or decompose the composition of the compound in the solution. In addition, since an extreme reaction field of ultra-high temperature and ultra-high pressure is formed at the time of crushing, it becomes possible to decompose and kill microorganisms such as bacteria and viruses that have been impossible in the past, such as phenol A compound containing an aromatic group can also be decomposed. Substances that can be decomposed by crushing include almost all organic compounds, inorganic compounds such as FeSO ₄ , CuNO ₃ , AgNO ₃ , MnO ₂ , dioxins, PCBs, chlorofluorocarbons, bacteria, viruses, etc. Can be mentioned.

  Since microbubbles rise at a slower rate than normal bubbles, by giving the microbubbles a stimulus such as causing vortex before the microbubbles disappear, the reduction speed can be increased and the collapse phenomenon can be prevented. Can be promoted. Thereby, sterilization and purification of livestock water are performed more effectively.

  In the present invention, the micro-ozone gas bubble-containing circulating water sent to the lower layer portion 32 is allowed to pass through the lower layer punching plate 35, thereby causing compression, expansion and vortex flow, thereby promoting crushing.

  The middle layer portion 33 is connected to the gas-liquid mixed water injection tube 27, and the gas-liquid mixed water is press-fitted and diffused into the animal culturing tank 31 from the gas-liquid mixed water injection tube 27.

  In the middle layer portion 33, the micro ozone gas bubbles generated from the lower layer portion 32 through the lower layer punching plate 35 become ultrafine bubbles due to the crushing, and the gas-liquid that is press-fitted and diffused from the gas-liquid mixed water injection tube 27. Mixing with the mixed water, the micro ozone gas is oxidatively decomposed and passes through the middle layer punching plate 36.

  An air diffuser 39 connected to the blower 38 is installed in the upper layer portion 34, and the air diffuser 39 sends the air sent in a pressurized state from the blower 38 to the upper layer portion 34. The reason why the air pressurized by the blower 38 and the air diffuser 39 is sent is to circulate aeration as a measure for eutrophication in the animal culturing tank 31, and the oxygen concentration in the animal culturing tank 31 by oxygen contained in the air. Will help to improve water quality. The pressure of the pressurized air is preferably 0.3 MPa or more, and the inside of the animal breeding tank 31 can be efficiently circulated and aerated. This air is mixed with the micro ozone gas bubbles that have passed through the middle layer punching plate 36 and passes through the upper layer punching plate 37.

  Micro-ozone gas bubbles and pressurized air that have passed through the upper punching plate 37 are compressed and expanded by the compression and expansion action when passing through the punching plate. The micro-ozone gas is crushed throughout the livestock tank 31 by accelerating and accelerating the flow of pressurized air. Thereby, the sterilization and purification action in the livestock tank 31 is performed as a whole. Moreover, eutrophication in the livestock tank 31 is also prevented by the pressurized air.

  The circulation purification sterilization system 4 is a system for purifying and sterilizing the animal feed water when circulating the animal feed water.

  The circulation purification sterilization system 4 includes a circulation water tank 41 that takes in and stores animal feed water in the animal breeding tank 31 as circulation water, and a circulation water pump 42 that sends an appropriate amount of circulation water to the filtration treatment tank 43 and the secondary reaction tank 44. A second ozone generator 45 for generating ozone, a third gas-liquid stirring and mixing device 46 for mixing the ozone gas generated from the second ozone generator 45 and the circulating water in the secondary reaction tank 44, and the micro ozone gas bubbles. It consists of a reaction receiving tank 47 for storing the contained circulating water, and a pressurizing pump 48 for pressurizing and sending the circulating water containing micro-ozone gas bubbles into the animal breeding tank 31.

  The circulation water tank 41 is connected to the animal cultivation tank 31 in order to take the animal cultivation water as the circulation water, and is configured to flow out to the circulation water tank 41 when the amount of the animal cultivation water in the animal cultivation tank 31 reaches a certain amount.

  The circulating water that has flowed out to the circulating water tank 41 is sent to the filtration tank 43 by a circulating water pump 42, and the filtration tank 43 removes dust and the like contained in the circulating water. Sent to.

  The ozone gas generated from the second ozone generator 45 is pumped to the third gas-liquid stirring and mixing device 46. The ozone gas is mixed and stirred with circulating water to form micro-ozone gas bubbles, and gas-liquid condensed and mixed to form micro-ozone gas bubble-containing circulating water. Here, microorganisms and harmful substances contained in the circulating water are sterilized and decomposed by oxidative decomposition of micro ozone gas bubbles, and the circulating water is sterilized and purified.

  The circulating water sterilized and purified in the secondary reaction tank 44 is sent to the reaction receiving tank 47. When a certain amount of circulating water containing micro ozone gas bubbles is stored, it is sent to the pressure pump 48. The circulating water containing micro-ozone gas bubbles sent from the reaction receiving tank 47 passes through the micro-ozone gas-containing circulating water injection pipe connected to the lower layer part 32 in the breeding tank 31 by a pressurizing pump, and the lower layer part 32 in the breeding tank 31. High pressure. Although the pressure which extrudes the micro ozone gas bubble containing circulating water of the pressurization pump 48 is not specifically limited, The pressure of 0.3 Mpa or more is preferable. Thereby, the micro ozone gas bubble-containing circulating water can be pressed into the lower layer 32 at a high pressure, and when the micro ozone gas bubble-containing circulating water passes through the lower layer punching plate 35, compression, expansion, and swirl are generated, and the crushing is efficiently performed. Can cause phenomena.

  The fine ozone bubbles diffused into the animal culturing tank 31 by the gas-liquid stirring and mixing device will be described with reference to a specific example compared with the conventional example.

  A feature of the present invention is to use ultrafine ozone bubbles and to crush them. Regarding the comparison of the effect with the conventional method, it can be evaluated based on the amount of free radical species and active oxygen species that bring about a bactericidal effect. First, there is an advantage of utilizing microbubbles, which is comparable in the ability of ozone to dissolve in water. When comparing the gas dissolution capacity of normal bubbles having a diameter of 1 mm and ultrafine bubbles having a diameter of 10 μm, the latter has a dissolution efficiency 20000000 times that of the former. There are three reasons, one is that the specific surface area acts inversely proportional to the diameter, and the other is that the self-compression effect of the bubbles is also inversely proportional to the diameter. The third is that the rising speed is extremely different. Small bubbles are almost based on the Stokes method, and a 1 mm bubble rises about 6 m per minute, whereas a 10 μm bubble rises only about 3 mm. When these three factors are simply multiplied, a difference in dissolution efficiency of 20000000 times is obtained. Next, regarding the amount of free radical species generated by crushing, it has been confirmed by preliminary tests that the effect is approximately 20 times that of the case where ozone simply acts. This is evaluated by the amount of element deposition due to the reaction of the KI solution, and the reaction proceeds at a rate of about 20 times under the condition in which the collapse of the micro ozone gas bubbles is caused compared to the simple action of ozone. When the effect is compared with the conventional method by simply multiplying the above two points, the present invention actually exhibits a sterilization effect of 400 million times. Under actual conditions, there are no obstacles to the occurrence of bubble contraction or crushing, but in any case, it is possible to exhibit an orderly sterilizing effect. Another advantage is that microbubbles of 10 μm or less are easily taken into the body of fish and shellfish, so that they easily act on sterilization of the body. Especially when a PSA system is used to generate ozone, the oxygen concentration is very high, which promotes the respiration and circulation of seafood and makes it easier for micro-ozone gas bubbles to be taken into the body. Will be obvious.

  As described above, the micro-ozone gas bubbles are supplied by the gas-liquid stirring and mixing device and are crushed, so that the fish and shellfish can be sterilized with low energy and in a short time.

  Residual ozone gas is strictly adjusted by bubble reduction and redox control.

  The above is one embodiment of the present invention, and the present invention is not limited to this. Alternatively, the first ozone generator 24 and the second ozone generator 45 may be combined into one to cause the intake water purification and sterilization system 2 and the circulation purification and sterilization system 4 to generate ozone, respectively.
