[Prior Art] In the waters of lakes or rivers, industrial wastewater discharged from various facilities such as factories or industrial sites built in the surrounding areas or household wastewater discharged from ordinary households will be discharged. Organic matter such as a phosphorus compound or a nitrogen compound, which causes pollution of the water area and causes water pollution. Here, as a method for improving the quality of the water thus contaminated, in recent years, there has been proposed a method of removing or reducing excessive organic substances in contaminated water (purified water) by microorganisms decomposing organic substances. Specifically, oxygen is supplied to microorganisms (aerobic microorganisms) in the purified water to activate the microorganisms, and the microorganisms are activated to promote decomposition of the organic matter and purify the purified water. In addition, due to the supply of nourishing gas, the microorganisms are proliferated, and the ability is improved. A knife supplies oxygen to the relevant microorganisms by using the oxygen-capacitor device described below, and is performed by dissolving oxygen in water obtained from the lake or river to be treated, and returning the dissolved oxygen water. Lake = or river (refer to Japanese Patent Laid-Open No. Hei 6_23387 (Fig. 3, Fig. 5, etc.), Japanese Patent Laid-Open No. 9-899 (Fig. 2, Fig. 3, etc.), and Special Guide No. 2000-317479 (paragraph [ 〇〇68], Figure 3, etc.)). The sweat dissolving device 100, as shown in Fig. 12, is provided with a container body 102 formed of a cylindrical member having pressure resistance and airtightness, and a bottom = 1307334 placed on the mounting member 109. Supporting; supplying oxygen to the oxygen supply mechanism 1 〇3 in the container body 102; supplying water (purified water) to the water supply mechanism 1〇4 in the container body 102; and water in the container body 1〇2 The drain pipe 105 is discharged, the diffuser plates 1〇6 and 107 disposed in the upper portion of the container body 102, and the water level detecting mechanism 1〇8 for detecting the water level in the container body 1〇2. Moreover, FIG. 12 is a schematic cross-sectional view showing a conventional oxygen dissolving device. The oxygen supply mechanism 103 is composed of an oxygen supply source 103a for supplying oxygen, a supply pipe 103b, and a supply valve 1〇3c. The supply pipe 103b is connected to the oxygen supply source 10a, and the other end is connected to the upper portion of the container body 102. The supply valve 1〇3c is supplied to the oxygen in the container body 102 from the oxygen supply source 103a through the supply pipe. The flow is adjusted. The oxygen supply mechanism 1 〇 3 supplies oxygen into the container body 2 and pressurizes the oxygen pressure inside the container body 102 to a pressure higher than atmospheric pressure. The water supply mechanism 1〇4 is composed of a pump unit 1〇4& and a water supply pipe 10b. The water supply pipe 1 is servant, one end is connected to the pump device l〇4a, and the other end is connected to the center of the upper part of the container body 1〇2. The drain pipe 105 is composed of a member having a diameter substantially equal to the inner diameter of the water supply pipe 1〇4b, and is connected to the container body from above the container body 1G2 and extends to the bottom of the container body at the lower end portion so as to be stored in the container body 1〇. The water at the bottom of the bottom 2 is discharged outside the container body 1〇2 by the oxygen pressure in the container body 102. The diffusing plates 106 and 1b are formed of flat members that are disposed at a predetermined interval from each other in the vertical direction, and have a plurality of through holes 106a and 107b having a small diameter and a small diameter. Further, each of the through holes 1〇6a and the through holes &7& are formed at positions shifted from each other in the horizontal direction. 1307334 The water level detecting means 10' is provided with an introduction tube 10a, which is attached to the outer peripheral surface of the container body 1〇2 in the longitudinal direction so as to extend in the vertical direction; a floating member (not shown) is placed in the introduction The tube 1 〇 8 & inside can be raised and lowered in the introduction tube, and the detectors 108a, 1 〇 8c are respectively disposed near the upper end of the introduction main body 1 〇 8a of the outer peripheral surface of the container body 1 、 2, and near the lower end, and the floating member is detected ( Not shown). The introduction pipe 108a is composed of a glass tube or a polyoxyethylene tube, and its upper end and lower end communicate with the inside of the container body 102. The floating member (not shown) is raised and lowered in response to the water level in the slab body 102. According to this oxygen dissolving device 100, first, oxygen gas is supplied into the container body 1〇2 by the oxygen supply mechanism 1〇3, and the oxygen pressure inside the container body 1〇2 is pressurized to a pressure higher than atmospheric pressure. Next, the purified water (water before the oxygen is dissolved) is "supplied" from the water supply pipe 104 to the container body 1〇2 by the water supply mechanism 1〇4, and the supplied water and the diffusion plate 106 are in contact with each other. The water droplets passing through f 1 扩散 on the diffusion plate become the water droplets of the vacancy plate and dripped from the diffusion plate 106. Thereafter, the dropped water collides with the diffusion plate 1〇7, and the same passes through the diffusion plates. 107' becomes a finer droplet and drops from the diffusion plate ι〇7. The SI water becomes a fine droplet, which makes the contact area with oxygen larger, and is efficient in the dripping process of the water. Dissolved oxygen. X, also because oxygen pressure inside the container body 102 is increased, oxygen can be efficiently dissolved into the water. In the 疋, the water under the oxygen atmosphere is stored in the bottom of the container 10 (10), so that the stored water (oxygen) The dissolved water is discharged from the drain pipe 105 by the oxygen 1307334 gas dust inside the vessel 胄1()2. Further, if it is stored at the bottom or the lower limit of the vessel body 102, it is detected by the water level detector #(10): Upper limit, when the water level rises and floats (not shown) In particular, the device _ is detected; when the water level drops, the detection by the magic is detected by the detector 108c on the lower side. Figure 2) The drop 'W water level exceeds the limit limit, and the detectors 108b, 108c When it is detected, the opening degree of the supply 妗Η ° e is adjusted to adjust the supply amount of oxygen, and the inside of the container body 102 is prepared, and the mountain and the Λ are adjusted so that the oxygen in the container "2 is adjusted. The displacement is maintained within a certain range of the ratio of the rolling and water. However, in the above-mentioned conventional oxygen dissolving device, the water is dripped (turned into water droplets) by the through holes 1〇6a of the diffusion counters 106 and 107, in other words, because the horse is expanded. Each of the through holes 1〇6a: 107a' of 106 and 107 has a flow rate of being extremely small, so that there is a problem that the processing capacity is low (the amount of water in which the oxygen is dissolved by the gas dissolved in the dissolved water) is small. Further, the water restricted by the expansion board 106, 1 〇 7 is filled between the diffusion plate 106 and the diffusion plate 1〇7, or between the diffusion plate 1〇7 and the top surface of the container body (10) to make oxygen It is not possible to supply the space below the diffuser plates i〇6, i to generate oxygen in the side m, and the agricultural degree is lowered, and the amount of oxygen dissolved in the water is also lowered. In particular, when the industrial waste water and the domestic wastewater contain other foreign matter such as garbage, the other foreign matter is likely to block the respective through holes i〇6a and 1〇7a of the diffusion plate 1〇6 107, and the above problem is easily caused. When each of the beacon holes l〇6a and l〇7a is blocked by foreign matter, the macro body 102 needs to be decomposed and the foreign matter removal operation is blocked. Therefore, the cost of the device will be raised; if, in order to remove the foreign matter On the other hand, the structure in which the container body is solved at 1 〇 2 also causes a problem that the manufacturing cost is high and the airtightness of the container body 1 〇 2 is insufficient. In addition, the diameter of the water supply pipe l〇4b is approximately equal to the inner diameter of the drainage f 1G5. However, when the oxygen in the container body 1〇2 rises, the displacement will be changed compared with the water supply amount. There is a problem that the amount of water stored in the container body 1〇2 tends to be small. ^'If Rong (4) 1G2 (4) The water level drops below the lower limit = machine... When measured, the opening of the supply 1〇3 is adjusted by . When the drain is $, the time at which the water level returns to m is lowered below the opening of the drain pipe 105, and there is a problem that oxygen in the body is leaked to the outside by the drain pipe 105. =, in view of the above actual situation, to provide a kind of f for the purpose. The gas dissolving device has a high processing ability and can be ▲' when the gas is dissolved in water. In order to achieve the above object, the present invention provides a container body having a sealed space in each of the solution bodies, and a supply pipe through which the gas is supplied through the supply The body mechanism 'has been connected to the body, and the gas pressure inside the container body is added:: supplied to the container knife is pressurized to above atmospheric pressure 1307334, the water supply mechanism has a water supply pipe connected to the container body, Water is supplied to the container through the water supply pipe; and a drain pipe is connected to the container body to discharge the dissolved water stored in the bottom of the container body, so that the water and the gas are in gas-liquid contact due to the inside of the container body. 'The gas is dissolved in the water; the water supply pipe has one end side disposed in the container body in the up-down direction, and has a discharge port opened at the upper end surface, and the discharge port faces the container body The top surface of the water spits out. According to the invention, first, a predetermined rolling body (a gas dissolved in water) is supplied into the container through the supply pipe through the gas supply means, and the gas pressure inside the container body is pressurized to a pressure higher than the atmospheric pressure. Then, the water supply device supplies water to the water supply pipe (water before the gas is dissolved), and the supplied water flows through the water supply pipe, and then is discharged into the container body through the water discharge port. The water that has been ejected is sprayed upward in the direction of the top surface (radially in the center of the discharge port), collides with the inner surface of the container body such as the top surface and the inner circumferential surface, or flows along the inner surface or bounces back and falls. The inner space of the container body flows along the outer peripheral surface of the water supply pipe, and then is stored at the bottom of the container body. However, during the flow of the gas atmosphere, the gas in contact with the water is dissolved. Further, the water which is sprayed upward in a radial direction is capable of efficiently dissolving more gas because the contact area with the gas becomes larger. Furthermore, since the gas pressure inside the container body is increased, the gas can be efficiently dissolved in the water, and then the water stored in the container body (water after the gas is dissolved), due to the gas pressure inside the body of the 1307334 The container is discharged through the drain pipe. Therefore, by using the gas dissolving device according to the present invention, since the water is sprayed upward from the discharge port to make the contact area of the water and the gas larger, the water can efficiently dissolve more gas, that is, Yes, it is possible to generate water that dissolves a high concentration of gas. Further, as in the above conventional oxygen dissolving device, even if a diffusion plate is provided in the container body, since the contact area with the gas is increased by A, the flow rate of the falling water is not limited, and a large amount of water can be efficiently treated. and

Moreover, the supply of gas is not hindered by the water limited by the diffusion plate. In addition, since the foreign matter does not block the diffusion plate, it is not necessary to perform the operation of removing the foreign matter, and the maintenance cost can be reduced. II can simplify the container because the diffusion plate and the container body are not required to be removed, and the foreign body is removed. The structure of the body reduces the manufacturing cost and improves the airtightness of the container body. Further, the gas dissolving device is preferably further provided with: an i-th flow control member that protrudes inward from an inner surface of the container body, and discharges the discharge port toward the top surface and along the inner surface of the container Flowing

Water flows from the protruding end of the first flow control member to the inner space of the container body. According to the above configuration, the second flow control member can be used to control the flow of water flowing along the inner surface of the container, and the water flows from the protruding end of the first flow control member to form a film and a waterfall. In the inner space of the container body, therefore, both sides of the water film can be in contact with the gas, and more gas can be efficiently dissolved in the water. In addition, it is preferable that the gas dissolving device further has the following configuration: 12 1307334 A plate-shaped second flow control structure that protrudes outward from the outer peripheral surface of the one end side of the water supply member, is discharged from the discharge port toward the top surface, The water flowing along the water supply pipe=circumferential surface flows from the protruding end of the turbulent flow control member to the inner space of the container body. In the same manner as described above, the second flow control member = the flow of water flowing along the outer peripheral surface of the water supply pipe, and the flow of the water from the protruding end of the second member flows in a film form and falls. In the inside of the container body, in the space, both sides of the water film can contact the gas due to &, and more gas can be efficiently dissolved in the water. The first flow control member is composed of a plate-like member which is formed by the inner surface of the container body facing the inner side, and the hole is preferably the same. At the time, there are several penetrations that have passed through the watch! The water that controls the flow of water by the flow control member c of the first flow control member and the second flow control member, the protruding end of the flow control member, the flow control member, and the second flow path, and the flow through the through holes. Can handle a large amount of water more efficiently. In addition, the size of the white female and female babies falls into the size of the hand, and most of the water drops fall..../Because the Betong hole, ^ ^ ^ and the sacral membrane and the waterfall flow down ^ 啁 area becomes larger, and can be more The multi-gas separation rate is dissolved in the water. In addition, the first control member of the first flow control member or the second control member is formed by the fact that t is a wave shape in a plan view, so that the circumference is good. The flow control member and the & b θ "the edge of the waterfall" and the lower tk Μ $ or the second control member in the form of a film and: the surface area of the water under the cloth 1 is added, and the energy area can further The contact of the gas sorghum body is dissolved in the water. 3〇7334. Further, the container body is formed such that the top surface is formed outward or inside, and the spherical curved surface is larger. The water that is ejected from the discharge port and collides with the top surface of the container body 2 flows along the top surface toward the second flow control member, and flows through the first flow control member to flow into the internal space of the container body. 'It can increase the amount of dissolved gas in water. ▲In addition, the inner diameter of the above-mentioned drain pipe is substantially the same as the inner diameter of the water supply pipe or the rut is small. Thereby, the water stored in the container body can be made. The discharge becomes difficult, so that the gas pressure in the container body becomes a high pressure, and the water flowing in the sea gas atmosphere can efficiently dissolve more gas. Both, even if the pressure in the gas rises for some reason It is also difficult to make the water level in the thief inside, 廿 & Down "effectively prevent the water level dropped to the so-called row

In the case of the opening of the water & The gas inside is leaked from the drain pipe to the outside. In addition, the gas supply mechanism is preferably connected to the upper spleen, the spleen of the spleen, and the sprinkler outlet of the water supply pipe. +, the gas is spit out together with the above water. · By means of 'water and gas mixed with water, at the same time make the contact in the water supply pipe can dissolve its body in a quantity of gas more efficiently dissolved in::... side flow' and thus can be more, the above water supply pipe, The best department narrowed its section. In this way, it is possible to dissolve a large amount of gas more efficiently by increasing the flow rate of the water discharged from the discharge port at the discharge port by the squirrel discharge rate: a gas that can be mixed while discharging: 'More efficient and multi-dissolved solution: ^ 14 1307334 [Embodiment] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The water of the through hole 6a of the 篦1^4 page is controlled to flow, so that the inner circumference of the third flow control plate 8 of J, the wy 彳 (dog end) is film-like, and the tomb i flows to the inside of the container body 2. In space. The water level detecting device 9 is formed in the outer peripheral surface of the tube 9a, 2, and is formed of the following members: The container system is attached to the container system by a light-transmitting material such as glass or resin. The two water level sensors 18 1307334 9b, 9c are arranged in the outer peripheral surface of the container body 2 near the upper portion of the introduction tube. In the introduction pipe 9a, the upper end portion and the lower end portion communicate with the inside of the container body 2, so that the liquid level position in the introduction pipe 9a rises and falls in accordance with the water level in the container body 2, and the water level sensors 9b and 9c detect the liquid. Face position. Further, the upper end portion of the introduction pipe 9a' is connected to the container body 2 at an intermediate position between the i-th flow control plate 6 and the second flow control plate 7, and the lower end portion thereof is connected to the container port 2 to the drain hole of the drain pipe 5. & above location. Thus, by the water level detecting device 9, when the water level in the container body 2 rises, the liquid level position in the introduction tube 9a also rises, and is detected by the upper water level sensor 9b, and the inside of the container body 2 is judged. The water level exceeds the upper limit, and the opening of the supply valve 3c is adjusted to increase the supply of oxygen. Thereby, the oxygen pressure in the volume body 2 is increased, the amount of water is increased, and the water level in the container body 2 is lowered. On the other hand, when the water level in the container body 2 is lowered, the liquid level position in the introduction tube % is also lowered, and is detected by the water level sensor 9c measured below, and it is judged that the water level in the container body 2 exceeds the lower limit, and the supply valve is adjusted. The opening of 3c reduces the supply of oxygen. Thereby, the oxygen pressure in the container body 2 is lowered, the amount of water is reduced, and the water level in the container body 2 is increased. According to the oxygen dissolving device i of the present embodiment configured as described above, first, the oxygen supply source 3a supplies oxygen to the container body 2 through the supply pipe 3b and the first water supply pipe, and the oxygen pressure in the container body 2 is increased. Pressurize above atmospheric pressure. Next, the purified water (water before oxygen dissolution) 19 1307334 is supplied by the pump device 4e: after the water supplied to the water supply pipe 4b' flows through the second water supply pipe 4b, the water supply pipe 4a of the younger brother 1' The supply pipe is supplied with a mixture of oxygen, and flows through the side while contacting the vertical side! The water supply pipe 4a is discharged by the discharge port & The water after the soil is sprayed upward in the direction of the top surface (the radial direction of the discharge port 4c is medium to the radial direction) (refer to the arrow C1 in Fig. 5), but the water sprayed upward is due to the inner diameter of the discharge port 4e. It is smaller than the other portions of the first water supply pipe 4a. Therefore, the pressure at the time of discharge is increased to increase the flow velocity, and the radiation is sprayed upward in a wider range. The water that is sprayed from the discharge port 4c but blows upward, collides with the top surface or the inner peripheral surface of the container body 2, and flows downward along the top surface and the inner peripheral surface (see the arrow) (not shown) And flowing downward along the outer peripheral surface of the first water supply pipe 4a, and then the flow is controlled by the first flow control plate 6, and the through holes 6a of the first flow control plate 6 flow into the container in a film shape and a waterfall shape. In the internal space of body 2 (see arrows C3 and C4). Next, the water that has flowed down by the first flow control plate 6 or the water that has bounced back through the respective through holes 6a of the first flow control plate 6 is used by the second flow control plate 7 to perform the caller' The outer peripheral portion of the second flow control plate 7 flows into the inner space of the container body 2 in a film shape and in a waterfall shape (see arrow c5). Then, the water that has flowed down through the first flow control plate 6 and the second flow control plate 7 or the water that has bounced back through the respective through holes 6a of the first flow control plate 6 is performed by the third flow control plate 8 The inner peripheral portion of the third flow control plate 8 flows into the inner space of the container body 2 in a film form and falls like a waterfall (see arrow c 6 ), and is stored in the bottom of the container body 2 . 20 1307334 Thus, in the process of the production of τ ^ , the water supply pipe 4a and the container body 2, the oxygen in contact with the water is dissolved. At this time, the overpressure is increased, and the oxygen in the energy of 2 is dissolved in the water. Thereafter, the water (water dissolved in oxygen) stored in the container body 2 is discharged by the drain pipe 53 due to the oxygen house force inside the container body 2. The water level of the water stored in the container body 2, if exceeded, may be determined by the water level detecting mechanism 9 u eight upper or lower limit ... liquid level position:: upper:::. When the water level exceeds the upper limit, when the inlet pipe exceeds the lower limit, the 7-position sensor 91 in the inlet pipe 93 detects the water level.

9. detected. The liquid level is sensed by the water level on the lower side. If the water level sensor is used, the opening of the supply valve 3c is adjusted to adjust the ratio of the oxygen pressure in the container body 2 to a certain range. 9b, 9c detects that the water level exceeds a certain limit, and adjusts the oxygen supply amount, thereby making the oxygen and water in the container body 2 long and difficult, because the drain pipe 5 diameter D2 and the water supply pipe 4卜 4 5| ^ .. 炙円仏D1 is the same or smaller,

The water in the burglary 2 is difficult to discharge. The water in the volume W 2 is easier to store. The oxygen pressure inside the 2 can be raised to a higher pressure. Gas is equal to sputum, dissolved in water, originally contained (dissolved) within 2, and the principle of heart is released from the water, thus nurturing the oxygen; the degree of farming will decrease, and the team μ, A falls Reducing the amount of oxygen dissolved in water, in order to discharge the oxygen in the container body 2... Holding a gas such as nitrogen gas in a certain amount or more. Specifically, first, the supply and the σ valve 3e are closed, and the supply of oxygen to the container body 21 1307334 is stopped, and then the exhaust chamber 1〇a of the exhaust pipe ○0 is opened to allow the inside of the container body 2 to communicate with the outside. Thereby, the gas (4) inside the container body 2 is lowered to the same level as the atmospheric pressure, and the water pipe 5 stored in the container body 2 is discharged. Next, the water supply pipes 4a and 4b further supply the water in the container body 2 to raise the water level in the container body 2, and discharge the container body 2 exhaust pipe 10 to the outside of the container body 2. Thus, as long as the oxygen is dissolved by the oxygen of the present embodiment, the water is sprayed upward by the discharge port 4e to increase the contact area between the water and the oxygen, so that more oxygen can be efficiently dissolved in the solution. In water, that is, water capable of dissolving a high concentration of oxygen can be produced. i In the above-described conventional oxygen dissolving device, even if the diffusing plates (10) and 1G7 are not provided in the container body 2, the contact area with oxygen can be increased, and the water is not restricted by the diffusing plates 106, 107. When the flow rate is dropped, a large amount of water can be efficiently treated, and when a gas such as nitrogen gas is discharged, the water level in the container 胄102 can be rapidly increased to rapidly discharge the gas. Furthermore, the supply of oxygen is not hindered by the water limited by the diffusion plates 106, 1〇7. Furthermore, since other foreign matter such as garbage does not block the diffusion plates 1〇6 and 1〇7, it is not necessary to perform the removal of the foreign matter f, the maintenance f can be reduced, and the diffusion plates 106, 107 and the container body 102 are not required to be provided. In order to remove foreign matter, the structure of the container body 102 can be simplified, the manufacturing cost can be reduced, and the airtightness of the container body can be improved. Moreover, the flow control is carried out by the respective flow control plates 6, 7, and 8, and the water flow film is flown into the internal space of the container body 2 in a film shape and a waterfall shape from the respective control flow 22 1307334 plates 6, 7, and 8. Both sides can be exposed to oxygen, and more oxygen can be dissolved efficiently. Furthermore, by setting a plurality of flow control plates 6, 7, 8 and increasing the number of times of water flow control, changing the flow state of the water increases the number of times the water is in contact with oxygen, thereby thereby dissolving oxygen more efficiently. Further, since the outer circumferential surface of the second flow control plate 7 and the inner circumferential surface of the third flow control plate 8 are formed in a zigzag shape, the circumferential length of the outer circumferential surface and the inner circumferential surface is increased, so that the second flow control plate 7 can be formed. And the third flow control plate 8 is formed in a film form and has a waterfall-like surface area, and increases the contact area with oxygen, so that more oxygen can be efficiently dissolved in the water. In addition, the upper portion of the trough body 2 is formed as a spherical curved surface that protrudes outward, and the water that is discharged from the discharge port 4c and collides with the top surface of the container body 2 flows toward the first flow control plate 6 side, and By flowing down the inner space of the container Μ 2 by the flow control plate, the oxygen is dissolved in the water, and the upper end surface of the first water supply pipe 4 & is disposed on the upper surface 4 of the container body 2, because the water is In the container body 2, the county # is discharged from the discharge port 4c, and the π port 4c can be discharged, and the container body is separated, whereby the oxygen dissolved amount of the water can be further increased.卩 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留 留The water in the container body 2 is difficult to pressurize to a higher pressure, and the water flowing in the atmosphere of the kneading can be facilitated by the Gusaki meat. Hai has "7 efficiency to dissolve more oxygen. 23 1J07334 And 'even the container body? The milk pressure of the water in the container body 2 rises for some reason, and is lowered to the opening/lowering of the opening of the drain pipe to effectively prevent the so-called water level from leaking to the outside. The oxygen inside is drained by the drain pipe, so that the water and the gas are mixed into the water, and at the same time, the sputum is dissolved, so that the body can be dissolved in a large amount of oxygen: effect: the water inside is spitting out... flowing, the hole is rolled more Efficiently dissolved in water.

Eight is the Γ! The inner diameter of the outlet 4c is smaller than the other knives of the first water supply pipe, and: the dust force at the time of discharge is increased, the flow velocity is increased, and the radial output of the ventilating shed (4) can be It is more efficient to dissolve the water in the evening, and the oxygen mixed with water in the second water supply pipe 4a can be dissolved in the water more efficiently and in large quantities. In the case where the first water supply pipe 4a is disposed at a position coaxial with the container body 2, the water discharged from the outlet 4c can be uniformly dispersed into the container body 2, and the treatment can be performed efficiently. The second implementation is also twirling
