The present invention relates to an aeration apparatus that can be used for water treatment facilities for biological treatment of wastewater, such as livestock wastewater containing a large amount of organic matter, or for storage water purification of lakes, and more specifically, aeration of wastewater or stored water continuously. And by installing various types or multiple stages of vortex generating partition walls in the tube of the aeration device for circulating and purifying, the treated water rising as the high pressure air generated in the diffuser nozzle is discharged while vortexing at the same time as the aeration in the aeration pipe. Oxygen is more smoothly contained in the treated water to facilitate oxygen dissolution, and the present invention relates to an oxygen-aerated aeration device that makes it possible to effectively purify wastewater or storage water such as lakes using the same. .

Aeration promotes microbial activity in water by blowing air into the water to be treated to increase oxygen, and decomposes organic matter by activities of aerobic bacteria or protozoa to treat sewage and wastewater such as livestock sewage. Waste water treatment method used in the law, aeration tank is used to treat the waste water through such aeration.

However, until now, by storing the waste water introduced through the sedimentation tank in the aeration tank, and by spraying air through the acid pipe, the aeration to treat the waste water by supplying oxygen to the water.

On the other hand, in addition to the conventional aeration process that simply blows air through the diffuser in the aeration tank in this way, the aeration pipe and the aeration tank using the same to increase the purification efficiency while allowing the circulation of water by using a high-pressure air blowing force for aeration Known.

That is, in the aeration tank, a separate aeration pipe is disposed therein, and by spraying air at high pressure through the air diffuser nozzle, the waste water flowing into the lower portion of the aeration pipe is more concentrated by the diffuser in the aeration pipe. Since the circulation of the water discharged onto the surface of the aeration tank is made through the upper portion of the aeration pipe by the injection pressure, the wastewater purification efficiency in the aeration tank is improved more than the conventional aeration tank.

However, by using the high pressure air applied from the air diffuser nozzle, forced water is circulated to generate a vortex of a desired type inside the width pipe that facilitates dissolved oxygen, thereby further smoothly dissolving oxygen in the treated water. No aeration system has been proposed.

Therefore, in the present invention, an arbitrary vortex is generated in the flow of the treated water inside the width pipe that enables circulation of the treated water, thereby facilitating oxygen dissolution, and in particular, in the discharge of the width pipe, It is intended to propose a technique for generating a greater amount of bubbles in the treated water passing through the discharge partition to increase the purification efficiency of the waste water.

The present invention has been made in order to improve the conventional problems as described above, the object is to install a plurality of or multi-stage partition wall means in the tube of the aeration apparatus for continuously circulating and aerated treatment of waste water or stored water. By doing so, the treated water rising as the high-pressure air generated from the acid nozzles is discharged while vortexing at the same time as the aeration in the aeration pipe, so that oxygen can be more smoothly contained in the treated water, thereby making it easier to dissolve oxygen. Therefore, the present invention is to provide an aeration device that is easy to dissolve oxygen, which improves the efficiency of treating and purifying the storage water of waste water, lake, etc. of the water treatment facility.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 and FIG. 2 show a state in which the aeration device 1 of the first embodiment of the present invention is easily dissolved in a water tank, for example, an aeration tank 400.

That is, the aeration device 1 of the first embodiment of the present invention is installed in the aeration tank 400 for treating the wastewater containing substantially a large amount of organic matter, such as livestock wastewater, which is used to treat the organic matter in the treatment of the wastewater. In order to purify by aeration, the aeration device 1 of this invention is installed in the aeration tank 400 mostly.

At this time, as shown in Figure 1, the aeration tank 400 is installed aeration device 1 of the present invention is disposed inlet pipe 402 for introducing the waste water, ie waste water, that is, through an anaerobic tank or sedimentation tank, etc. On the surface of the water, a discharge pipe 404 for discharging the purified water on the surface (treated water), which is purified by aeration and circulation, is discharged to a discharge tank of the next process, for example, a water treatment facility.

However, although the discharge pipe 404 is shown in the figure, it is also possible to actually discharge the treated water to the next water treatment tank, for example, the sedimentation tank in the form of a monthly flow.

That is, in FIG. 1, only the aeration tank 400 in which the aeration device 1 is disposed is shown in the present invention. However, in order to actually remove the wastewater by the biologically active sludge method, the wastewater inflow tank is moved back and forth in the aeration tank. A discharge tank for discharging the settling tank or the settled treated water is used in connection with one facility, and the other tanks are not shown in the drawings.

At this time, as shown in Figures 1 and 2, the aeration device 1 of the present invention as a first embodiment is largely divided into a tubular body 10, an air nozzle 30 and the vortex generating partition means (50) The tubular body 10 may include at least one inlet 12 through which water is introduced and a discharge port 14 for discharging the aeration circulation water onto the water surface.

In this case, the tubular body 10 may be a pipe, for example, a pipe of a material that is not easily corroded or a pipe formed of a resin material, and the tubular body 10 may be a water tank, for example. While standing vertically fixed to the bottom of the aeration tank 400, the upper end, that is, the discharge port 14 should be adjusted in length so as to be exposed above the water level of the waste water stored in the aeration tank 400.

1 and 2, the inlet 12 formed in the tubular body 10 is the tubular body 10 when the tubular body 10 is blocked and fixed to the bottom of the aeration tank 400. A plurality of inlets 12 are formed in the circumferential direction of) so that the acid action of the air diffuser nozzle 30, that is, the high pressure air is injected from the inside of the pipe, causes water introduced through the inlet 12 by the head. It is aerated as a high-pressure air injected from the at the same time forced to circulate through the pipe to rise vertically along the pipe is discharged on the surface of the aeration tank 400 in the discharge port (14).

Next, in the aeration apparatus 1 of the present invention, the air diffuser nozzle 30 is disposed in the lower side of the tubular body 10 and is configured to diffuse high pressure air to enable aeration and circulation of water in the tube. It is.

Therefore, the aeration device 1 of the present invention is oxygen in the aeration tank, for example, oxygen as a high-pressure air injected in the sealed interior of the pipe to the primary treated sewage and wastewater through the inflow tank and the sedimentation tank in the water treatment facility. As the melting of the aeration takes place, at the same time, an upward flow of water is forcibly formed, and finally, the wastewater in the aeration tank is forced to circulate and aeration to improve the water purification ability.

On the other hand, as shown in Figures 2 and 3, the air nozzle 30 is bent to be fixed to the lower portion of the tube body 10 while being connected to the high-pressure air supply pipe 32 connected to the lower portion of the tube body (10) The high pressure air is applied to the water introduced into the tube body 10 through a plurality of nozzle holes formed and installed on the connection pipe 32.

At this time, the diffuser nozzle 30 is preferably formed in a conical shape, which is intended to facilitate the circulation of water by allowing the high-pressure air to be sprayed upwards inside the tubular body 10.

2 and 3, in the aeration device 1 of the present invention, the vortex generating partition wall means 50 is an upper side of the air diffuser nozzle 30 inside the tubular body 10. As shown in FIG. And a circulation water passage opening 52 configured to generate vortices to smoothly dissolve oxygen while temporarily blocking the circulation water, and to allow the circulation water to pass therethrough.

Therefore, in the first aeration device 1 of the present invention, the tubular body 10 is substantially connected to the flange portion (F) where the nozzle nozzle 30 and the vortex generating partition wall means 50 are respectively installed. It is composed of a multi-stage body (10a) (10b), 10c, which is a structure for enabling the installation of the air diffuser nozzle 30 and the vortex generating partition wall means (50).

On the other hand, as shown in Figure 3, in the upper tube body (10c) is formed of a plurality of discharge ports 14 of the tube body assembled in each other in the flange form (F), the other discharge port 14a formed in the circumferential direction of the tube body ), Which will facilitate the discharge of water discharged through the tubular body 10, and in the case where the discharge pressure of the mole, that is, the high pressure air blowing force injected from the air nozzle 30, is weak, Since it will be possible to more smoothly discharge through the 14a, the formation of such a discharge port 14a would be preferable.

On the other hand, as shown in Figures 2 and 3, the vortex generating partition wall means 50 is composed of a circular plate fixed to the inside of the upper nozzle body (10b) of the diffuser nozzle, the passage opening formed in the circular plate At least one 52 is formed.

Therefore, as shown in FIG. 2, the water introduced through the inlet 12 of the lower end 10a of the tube body 10 rises instantaneously while being aerated in the tube by the air blowing force in the air nozzle 30. While colliding with the vortex generating partition wall means 50, which is the circular plate, it collides primarily with the partition wall means 50. At this time, a vortex phenomenon is generated in which water flow is entangled forcibly. Since air is injected, the vortexed water is discharged to the tube discharge port 14 side through the passage opening 52 of the partition wall means 50.

Eventually, the water passes through the barrier means 50, and a considerable collision occurs, and bubbles are generated. This action makes the oxygen dissolved as much as the oxygen is dissolved in the water, thereby facilitating the oxygen of the wastewater. It is to further improve the purification efficiency of waste water by smoothing organic matter treatment by microorganisms while increasing the dissolution rate.

Accordingly, the discharge water discharged to the discharge port 14 of the tubular body 10 is formed in a larger amount of bubbles, of course, the discharge amount will be reduced than the case without the partition wall 50, but the discharge of the continuous circulation water The discharge amount of the discharged water does not matter much.

Next, Fig. 4 shows another example 1a of the aeration apparatus 1 of the first embodiment of the present invention.

That is, as shown in Figure 4, the vortex generating partition wall means 50 for generating vortices substantially in the flow of the aeration circulating water to facilitate oxygen dissolution, the tubular body is multi-stage, for example a total of four stages The tube body 10a, 10b, 10c, 10d is composed of a multi-stage, for example, installed in two stages inside the upper tube body 10c, 10d of the tube body connected in the form of a flange (F) Can be.

At this time, preferably, as shown in Figure 4, the two-stage partition wall means 50 are staggered to the opposite side with respect to the position of the circulating water passage opening 52 relative to the inner center line (C) of the tube body. To deploy.

Therefore, the rising water by the high pressure air injected from the air diffuser nozzle 30 first collides with the partition wall means 50 at the lower part and passes through the vortex, and then the circulating water passing through the passage opening 52 is again Since the second impingement to the other partition wall 50 again passes through the passage opening 52 through the vortex and is discharged on the water surface of the aeration tank 400 from the tubular body discharge port 14, the aerated and circulated water Since a large amount of oxygen is dissolved and contains a lot of bubbles in the discharge, it will make the water purification more smooth.

Next, Fig. 5 shows another example 1b of the first embodiment aeration apparatus of the present invention.

That is, as shown in Figure 5, another aeration device (1b) of the present invention increases the amount of vortex generation of circulating water below the passage opening 52 of the vortex generating partition wall means 50 to increase the acid loss dissolution rate It is further provided with an auxiliary partition wall body 70 integrally provided so as to increase.

At this time, the auxiliary partition wall 70 of the vortex generating partition wall means 50 is composed of a heavy-duty cylinder attached to the lower portion of the opening 52 of the partition wall means 50, and the circulating water collided by the partition wall means is induced to flow downward. It is further configured to increase vortex generation.

Therefore, when the water circulated in the tube by the high-pressure air blowing force of the air diffuser nozzle 30 collides with the partition wall means 50 to form a vortex, it further collides with the sidewalk partition wall 70 in the hollow park cylinder and passes directly therethrough. After passing through the opening 52 and passing through the more severe vortex, it is discharged through the passage opening 52 of the partition means 50.

As a result, in addition to having only one partition wall means 50, another first aeration device 1b of the present invention further provided with an auxiliary partition wall 70 will facilitate acid loss dissolving as much.

On the other hand, in the various examples (1) (1a) (1b) of the first aeration device described so far, as shown in FIG. 3, one or more passage openings 52 of the partition wall means 50 are formed. For example, if the inner diameter of the aeration tube body 10 is too large, the number of passage openings 52 is too small compared to the amount of water circulated, and thus it may be possible to arrange three at a constant rate.

At this time, since the number of the through openings 52 has a proportional effect on the discharge amount, the number of the through openings or the clearance may be adjusted according to the size of the aeration device.

Next, Fig. 6 shows another example 1c of the first aeration device according to the present invention.

That is, another first aeration device 1c of the present invention is provided with the partition wall means 50 including the auxiliary partition wall 70 in multiple stages as shown in Fig. 4, and the position of the passage opening 52 is a pipe. It is arranged to be staggered with respect to the inner core wire (C) inside the body.

As a result, the aeration device 1c is the most complicated structure of the aeration devices described so far, but the oxygen dissolution is most smooth.

Therefore, it would be desirable to selectively use the various first aeration devices (1) (1a) (1b) (1c) of the present invention in accordance with the working conditions of the wastewater and wastewater.

Next, Figs. 7 and 8 show a second embodiment 100 of the aerator according to the present invention.

That is, as shown in Figs. 7 and 8, the second aeration device 100 of the present invention, having an inlet 112 through which water is introduced and a discharge port 114 for discharging the aeration circulation water onto the water surface, It is configured to include at least one tube body 110 is installed in the inside, and the nozzle nozzle 130 is fixed to the inner lower portion of the tube body 110 to diffuse the high-pressure air to enable aeration and circulation of water. For the sake of clarity, the same components as those of the first aerators are denoted by symbols of 100 units, and detailed descriptions of the configuration and operation are omitted.

On the other hand, in the second aeration device 100 of the present invention is injected into the upper part of the diffuser nozzle 130 through the tube body 10 is fixed and the injection pressure of the high pressure air injected with a circulating water passage opening 152 It is provided with a separate vortex generating partition wall means 150 configured to generate vortices to smoothly dissolve the oxygen while temporarily blocking the circulation water circulated in the tube.

That is, as shown in Figures 7 and 8, the second aeration device 100 of the present invention is to provide a partition means in a separate type.

At this time, the tubular body 110 is a multi-stage body (110a), for example, a two-stage body where the nozzle nozzle 130 and the separate vortex generating partition wall means 150 are arranged in a flange form (F) with each other. It consists of 110b.

In addition, the upper tube body 110b of the tube body 110 is formed with at least one integrally cut incision 116 in the vertical direction along the tube body, the separation vortex generating means 150 is the insertion dissection The circular plate is inserted and fixed through the portion 116, the partition wall means 150 of the circular plate is formed with at least one passage opening (152).

Therefore, the second aeration device 100 of the present invention, because the partition wall means 150 for forming a vortex in the circulating water to facilitate the oxygen dissolution is inserted through the insertion incision 116 from the outside of the tube body 110. According to the installation environment of the aeration device 100, it is possible to use a plurality of circular plates in which the number of the openings 152 of the installation is different, thereby providing an advantage of broadening the responsiveness of the aeration device.

At this time, as shown in Figures 7 and 8, the separate vortex generating partition wall means 150 is inserted into the incision 116 is in close contact with the thickness of the tube body 110, not a complete circular plate. The close contact jaw 156 is integrally formed, and the packing 154 blocks the water leakage while increasing the coupling strength fitted to the insertion cutout 116 of the tubular body 10b in the separate partition wall means 150. ) May be attached to the upper and lower surfaces.

On the other hand, as shown in Figure 8, the separate vortex generating partition wall means 150 of the present invention is also formed by forming a plurality of incisions 116 in the upper tube body 110b of the tube body 110 It will be possible to arrange, the position of the through-opening openings 152 formed in the circular plate of the partition wall means 150 is most preferably to be arranged to be opposite to each other on the basis of the inner center line (C) of the tube body, which is the front This is because the circulation water impinges on the partition means many times as described, and more oxygen dissolved circulation water is discharged through the secondary vortex.

Next, FIGS. 9 and 10 illustrate a media 300 additionally provided to the present inventors' aerators.

That is, the media 300 is a synthetic resin, for example, woven with fine yarn on the synthetic resin string 304 connected to the fixing base 302 fixed to the inner lower portion of the upper tube body 10a of the tube body 10, for example, polyethylene, etc. Fluffy 306 is made of attached, the organic matter contained in the circulating water (waste, waste water) flowing inside the tube while the microorganisms contained in the circulating water is attached to the fluffy 306 of the media 300 smoothly attached It is to decompose the water to increase the purifying power that much.

At this time, since the fluffy 306 of the media 300 is larger in surface area, more microorganisms can be attached to facilitate the decomposition of organic matter in the water, so that the media 300 does not interfere with the circulation of water. It will be preferable to arrange the approximately 4-5 lines inside the tubular body 10.

Meanwhile, although the media 300 is not shown in the second aeration device 100 of the present invention in FIGS. 7 and 8, the other tubular body is connected to the upper tubular body 110b in the form of a flange (F) and the inside thereof. It will be possible to place the media 300 in the.

Next, FIG. 11 and FIG. 12 show a third embodiment 200 of the aerator according to the present invention.

That is, as shown in FIGS. 11 and 12, the third aeration device 200 of the present invention includes an inlet 212 through which the stored water flows and a discharge port 214 for discharging the aeration circulation water onto the storage water surface. At least one or more disposed, the tube body 210 is configured to be variable in length depending on the level of the storage water, and to diffuse the high-pressure air in the inner lower portion of the tube body 210 to enable aeration and circulation of water Circulation is circulated in the tube by the injection pressure of the high pressure air sprayed with a spray nozzle 230, and the inside of the pipe body 210 to the upper side of the diffuser nozzle 230 and equipped with a circulating water passage opening 252 It is configured for purification of the storage water, including the vortex generating partition wall 250 configured to generate vortices while temporarily blocking the water to smooth oxygen dissolution.

Accordingly, the third aeration device 200 of the present invention does not have an aeration device installed in the aeration tank as shown in FIG. 1, but stores water that is easily contaminated due to little flow of water, such as a lake. Forced aeration circulation inside to continuously purify the mixed water is easy to mix, in particular to increase the oxygen dissolution rate through the barrier means (250).

At this time, in the third aeration device 200 of the present invention, the diffuser nozzle 230 and the partition wall means 250 have the same configuration as the diffuser nozzle and the partition wall means of the first aeration device 1 shown in FIGS. 1 and 2. For the sake of understanding, 200 units of code are used and detailed descriptions of the construction and operation are omitted.

Therefore, in the third aeration device 200 of the present invention, the first and second aeration devices and the other tubular body 210 are straight pipe bodies in which the diffuser nozzle 230 and the vortex generating partition wall 250 are fixed inside, respectively. 216) 218 and a bellows-shaped body 220 which can vary in length depending on the storage water level are connected to each other in a flange form (F).

That is, in the third aeration device 200, the bellows-type body 220 of the upper end of the tubular body is allowed to operate while the aeration device 200 is lying sideways when the water level is changed or changed.

At this time, in the third aeration device 200 of the present invention, the wire 222 connected to the weight 222 is connected to the lower end pipe body 216 of the tubular body 210, and the weight connection is performed by the third aeration device. The arrangement after the addition into the storage water of 200 is facilitated.

At this time, the inlet 212 of the tubular body 210 has a lower end portion of the tubular body is completely open or a plurality of penetrating through the circumferential direction along the tubular body.

Of course, the vortex generating partition wall means 250 is composed of at least one circular plate disposed inside the straight body 218, it may be possible that at least one passage opening 252 is formed in the circular plate.

And, the vortex generating partition wall means 250 is installed in multiple stages inside the straight body 218, the positions of the through opening 252 are alternately arranged on the opposite side relative to the inner center line (C) of the tubular body. Of course.

At this time, as shown in Figure 12, the vortex generation partition wall means 250, the hollow provided integrally to increase the acid loss dissolution rate by increasing the vortex generation amount of the circulation water to the lower side of the passage opening 252 provided It is also possible to further provide the auxiliary partition wall 270 of a cylindrical body, and the structure and operation | movement of this auxiliary partition wall body are as above-mentioned.

11 and 12, it will be possible to arrange the media 300 for attachment of microorganisms inside the tube body of the third aeration device 200 of the present invention for storage water purification. 300 is as described above.

11 and 12, the high pressure air supply pipe 234 connected to the connection pipe 232 of the air diffuser nozzle 230 in the third aeration device 200 includes a third aeration device ( Considering that 200) is introduced into a lake or the like, it is preferable to use a flexible pipe connected to an air compressor, for example, an air compressor on the ground.

In addition, although schematically illustrated in the drawings, if the depth of the stored water is deep, the length of the wire 222 may be extended to adjust the arrangement distance of the aeration device 200 according to the present invention on the surface of the water, for example, the depth of the water is too high. It is because it is difficult to discharge the circulating water smoothly through the discharge port 214 of the tubular body 210 even if the air is blown under high pressure by the water pressure.

Next, Fig. 13 shows another embodiment 200a of the third aeration device of the present invention.

That is, as shown in Figures 11 and 13, the aeration device 200a of another embodiment of the third aeration device of the present invention is connected to surround the outside of the tubular body 210, the tubular body discharge port 214 Floor is included in the circulating water discharged through the) is further provided with an outer tube body 290 to prevent the spreading on the water surface.

At this time, the outer tube body 290 is connected to the bellows-type body 290b and the straight tube body 290a corresponding to the bellows-type body 220 of the tube body 210 while being in a flanged shape (F). Is connected to the tubular body 210 side through a plurality of connecting bodies, for example bolt rods 292, and fixed to the bottom of the bottom foreign matter, for example, the discharge hole 290a sediment discharge discharged from the bottom of the lake ') Is a structure formed through.

Accordingly, as shown in FIG. 13, the water circulated by the air blowing force of the air nozzle 230 includes a bottom foreign matter such as a bee on the bottom of the lake, and the bottom foreign matter is discharged from the tubular body 210 ( When discharged from 212) immediately flows into the outer tube body 290, because the bottom foreign matter precipitates downward from the inside of the outer tube body 290, the aeration device 200a of the present invention includes the bottom foreign matter in the circulating water Even if it is, it will provide other benefits that effectively block spreading on the surface.

Of course, such an outer tube body 290 is preferably used when the inlet 212 is disposed in close proximity to the bottom of the lake where the stored water does not flow as shown in Figures 11 and 13, Once the position is up from the floor (ie, the length of the wire 222 is extended) it will not need to be used.

At this time, the microorganism attachment media 300 as described above is attached to the inside of the outer tube body 290, the microorganisms contained in the aerated and circulated water is more preferable to facilitate the purification of the water.

Accordingly, the aeration devices 1, 1a, 1b, 1c, 100, 200, and 200a of the present invention described so far inject high-pressure air from the inside of the pipe to perform aeration and circulation at the same time. By generating vortices of circulating water through the bulkhead means 50, 150, 250 and the auxiliary bulkheads 270, oxygen is smoothly melted and aerated and circulated by collision with the flow of water entangled in the pipe. To increase the efficiency of wastewater purification.

In addition, the aeration devices of the present invention are manufactured in various structures and can be selectively used where desired so that the aeration devices are excellent in use correspondence.

On the other hand, Figure 14 is a schematic photo showing the discharge form of the treated water (water) aerated and circulated through the aerator according to the present invention, as can be seen in the photo of Figure 14 bubbles are greatly increased It can be seen that it is discharged, and this is discharged again as the vortex is generated by the partition means during the aeration and circulation due to the high-pressure air spraying force, it can be seen that it is easy to dissolve the oxygen, which improves the wastewater treatment efficiency .

As described above, according to the present invention, the oxygen aeration device which is easy to dissolve has provided various types or stages of discharge partition walls inside the pipe of the aeration device for treating the wastewater by circulation and aeration, thereby increasing the high pressure generated in the air nozzle. The treated water rising as air is discharged as it is vortexed at the same time as the aeration in the aeration pipe, so the oxygen is more smoothly contained in the treated water to facilitate the oxygen dissolution, and the purification efficiency of the waste water or the stored water is further improved by using it. To provide an excellent effect.
