An intelligent control medical wastewater treatment system

Abstract

The present invention relates to the technical field of wastewater treatment, and specifically relates to an intelligent control medical wastewater treatment system, including a pool body, an ozone generator, and an injector. The ozone generator and the injector are both fixedly installed on the outer side wall of the pool body, and the output end of the ozone generator is communicated with the input end of the injector; an aeration plate, which is horizontally and fixedly installed in the pool body. In the present invention, the first motor drives the water pump to operate. Since the water inlet of the water pump is connected to the top of the pool body and the suction of the water pump is relatively large, when the bubbles are about to float to the water surface, the water and the bubbles around the bubbles will be sucked into the water pump together, and then flow out from the drainage port of the water pump and return to the pool body again. Since molecules move in an endless and random manner, when the bubbles enter the wastewater again, the contact probability between the ozone in the bubbles and the wastewater is increased, so that the wastewater and the ozone can be fully contacted, the production amount of ozone is reduced, and the cost is saved.

Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to an intelligent control medical wastewater treatment system. Background Art

[0002] The wastewater components in hospitals are very complex, containing many chemical substances, a large number of pathogenic bacteria and viruses, and having the characteristics of space pollution, acute infectious diseases and latent infections. Compared with industrial wastewater and domestic wastewater, it has the characteristics of small water volume and strong pollution. If it is discharged arbitrarily, it will seriously pollute the water source and cause unimaginable consequences.

[0003] When some existing medical wastewater treatment systems treat wastewater, they will oxidize the wastewater to remove bacteria and other microorganisms in the wastewater. The specific method is to introduce air or oxygen containing low-concentration ozone into the wastewater pool. Since ozone has strong oxidizing properties, when ozone contacts the microorganisms in the wastewater, it can kill them.

[0004] When the existing medical wastewater treatment system performs aeration oxidation treatment in the wastewater pool, small bubbles containing ozone are introduced from the bottom of the pool and then gradually float to the water surface. During this process, the bubbles contact the microorganisms in the water. However, during the upward floating process of the bubbles, the ozone inside the bubbles fails to contact the wastewater. At this time, the ozone is directly emitted into the air without being fully utilized, and it costs a certain amount to produce ozone. Therefore, the purification cost increases.

[0005] Therefore, an intelligent control medical wastewater treatment system is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent control medical wastewater treatment system to solve the problem that the bubbles contact the microorganisms in the water, but during the upward floating process of the bubbles, the ozone inside the bubbles fails to contact the wastewater. At this time, the ozone is directly emitted into the air without being fully utilized, and it costs a certain amount to produce ozone. Therefore, the purification cost increases as mentioned in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] An intelligent control medical wastewater treatment system, comprising:

[0009] A pool body, an ozone generator, and an ejector. The ozone generator and the ejector are both fixedly installed on the outer side wall of the pool body, and the output end of the ozone generator is communicated with the input end of the ejector;

[0010] An aeration plate, which is horizontally and fixedly installed in the pool body, and the output end of the ejector extends to the part below the aeration plate in the pool body;

[0011] It further includes:

[0012] A first motor fixedly installed on the side wall of the pool body;

[0013] A water pump, the drive shaft of the water pump is fixedly connected to the first output end of the first motor, and the water inlet and drain outlet of the water pump are respectively communicated with the top and bottom of the pool;

[0014] A collection mechanism, the collection mechanism includes a first bracket fixedly installed on the inner wall of the pool body, a transfer box is fixedly installed on the first bracket, a conduit extending vertically into the transfer box is rotatably installed on the top wall of the transfer box, a plurality of collection plates are uniformly fixedly installed at the top end of the conduit, diversion grooves communicated with the conduit are formed on the collection plates, and a water inlet pipe is fixedly installed between the water box and the water inlet of the water pump, and a second motor with an output end extending into the water box and fixedly connected to the conduit is fixedly installed on the bottom wall of the first bracket.

[0015] During the working process, first, the pool body is filled with waste water, and then the ozone generator is started. At this time, the ozone generated in the ozone generator is processed by the ejector and enters the aeration plate, and finally is discharged from the air holes of the aeration plate. When the mixed gas of ozone and air is discharged from the aeration plate, because the density of the bubbles is small, the bubbles float upward under the action of buoyancy. During the floating process of the bubbles, the ozone on the outer wall of the bubbles contacts the waste water. At this time, the ozone can kill the bacteria in the waste water contacted with it, thus realizing oxidation disinfection.

[0016] During the working process, the first motor is started, and the water pump is driven to operate by the first motor. Since the water inlet of the water pump is communicated with the top of the pool body and the suction of the water pump is large, when the bubbles are about to float to the water surface, the water and bubbles around the bubbles will be sucked into the water pump together, and then flow out from the drain outlet of the water pump and return to the pool body again. Because molecules do perpetual random motion, when the bubbles enter the waste water again, the contact probability between the ozone in the bubbles and the waste water is increased, so that the waste water can be fully contacted with the ozone, the production amount of ozone is reduced, and the cost is saved.

[0017] During the working process, the second motor drives the conduit to rotate. Since the collection plate is fixedly connected to the conduit, the collection plate also rotates during the rotation of the conduit. When the collection plate rotates, the waste water contacting the collection plate carries the bubbles into the diversion grooves together. Since the conduit is communicated with the water inlet of the water pump, the part where the conduit is communicated with the diversion grooves has strong suction, and the diversion grooves are communicated with the conduit, so the bubble water entering the diversion grooves will be absorbed into the conduit, thus realizing the function of introducing the bubbles into the pool body again under the action of the water pump.

[0018] The second motor drives the conduit to rotate rapidly, so the collecting plate also rotates rapidly, enabling a large number of bubbles in the water to be recycled in a timely manner, thus playing a role in improving the recycling rate.

[0019] Preferably, the surface of the collecting plate is an inclined plane.

[0020] Since the surface of the collecting plate is an inclined plane, when the conduit drives the collecting plate to rotate, the water in contact with the collecting plate is directly shoveled up, reducing the contact area between the collecting plate and the water body, thus playing a role in ensuring the normal rotation of the collecting plate.

[0021] Preferably, a water box is fixedly installed on the bottom wall of the first motor, a first drain pipe extending into the water box is fixedly installed on the drain outlet of the water pump, a second drain pipe extending into the pool body is fixedly installed on the bottom wall of the water box, and a barrel-shaped filter screen is arranged at a position above the second drain pipe in the water box.

[0022] Before the wastewater treatment, the larger-volume impurities in the wastewater will be removed. At this time, there are still smaller-volume impurities remaining in the wastewater. Therefore, when the bubbles flow out of the aeration plate, the bubbles adhere to the surface of the smaller-volume impurities. As the amount of bubbles on the surface of the impurities increases, the density of the impurities gradually decreases. Therefore, the impurities will float to the water surface. Under the action of the collecting plate and the conduit, the impurities will enter the diversion groove together with the bubbles and then enter the conduit along the diversion groove, and finally pass through the water pump and the first drain pipe and enter the water box.

[0023] When the bubble water carries impurities into the water box together, the water flow impacts the filter screen. At this time, the impurities in the water flow will be filtered by the filter screen. Therefore, the water flow passing through the filter screen is relatively clean, so that there are no particulate impurities in the wastewater returned to the pool, playing a role in preventing the bubbles from adhering to the surface of the impurities and resulting in a reduction in the contact area between the bubbles and the wastewater.

[0024] Preferably, a second support is vertically rotatably installed in the water box, the filter screen is fixedly sleeved on the second support, and the second output end of the first motor is fixedly connected to the second support.

[0025] Since the first motor drives the water pump to work during the operation process, the first motor rotates rapidly. Since the second support is fixedly connected to the second output end of the first motor, the first motor drives the second support to rotate rapidly. At this time, the filter screen rotates rapidly together with the second support. Therefore, the impurities adhering to the surface of the filter screen will be separated from the contact with the filter screen under the action of centrifugal force, so that the surface of the filter screen can be kept clean, playing a role in continuous filtration.

[0026] Preferably, a funnel with an upward opening is fixedly installed on the second support, and the cross-sectional area of the top end of the funnel is larger than the cross-sectional area of the second support.

[0027] When impurities are separated from the surface of the filter under the action of centrifugal force, the impurities will perform centrifugal motion in the water box. When they contact the inner wall of the funnel, the impurities will adhere to the inner wall of the funnel. Since the second bracket drives the funnel to rotate rapidly, the impurities attached to the inner wall of the funnel are also subject to horizontal outward centrifugal force. Since the side walls of the funnel are inclined, when the impurities are subject to horizontal outward force, the horizontal force also has a component force in the upward direction along the side walls of the funnel. At this time, under the action of the component force, the impurities gradually slide upward along the side of the funnel until they are separated from the contact with the funnel. Therefore, the impurities around the filter can be transferred in time, thereby preventing the effective filtration area of ​​the filter from being reduced due to the accumulation of impurities around the filter.

[0028] Preferably, a sleeve is vertically fixedly installed in the water box, the funnel is located inside the sleeve, and the cross-sectional area of ​​the sleeve is smaller than the cross-sectional area of ​​the top of the funnel.

[0029] Since the cross-sectional area of ​​the sleeve is smaller than that of the funnel, the impurities flying out from the inner wall of the funnel will splash into the space between the sleeve and the water box under the action of inertia, thereby collecting the impurities in the space between the sleeve and the water box.

[0030] At the same time, the sleeve is used to separate the impurities from the funnel, which prevents the impurities from piling up and squeezing the funnel, causing a large friction between the funnel and the impurities, thereby affecting the funnel rotation speed.

[0031] Preferably, a warning light is fixedly mounted on the top wall of the water pump, a switch electrically connected to the warning light is fixedly mounted on the inner bottom wall of the water box, and a trigger mechanism cooperating with the switch is provided in the water box.

[0032] When the impurities between the inner wall of the water box and the sleeve are filled, the switch is triggered by the trigger mechanism, and the warning light is lit. Since the warning light is bright, the staff can find it in time, thereby reminding the staff to clean up the impurities in time.

[0033] Preferably, the trigger mechanism includes an annular support plate, which is slidably mounted on the sleeve, and the side wall of the support plate is slidably and sealingly connected to the inner wall of the water box, a plug hole is provided on the support plate, and a guide rod passing through the plug hole is vertically fixedly mounted on the inner bottom wall of the water box, the support plate is made of magnetic material, and a magnet that repel each other with the support plate is fixedly mounted on the bottom wall of the water box.

[0034] Under the combined limiting action of the sleeve and the guide rod, the support plate can only move up and down along the sleeve and the guide rod without tilting or flipping, thus ensuring the normal up and down movement of the support plate. In the initial state, under the repulsive force between the magnet and the support plate, the support plate is located at the top of the sleeve. As the impurities on the surface of the support plate increase, the overall weight of the support plate also increases. Therefore, the support plate gradually moves down along the outer wall of the sleeve. Since the switch is installed on the inner bottom wall of the water box, during the downward movement of the support plate, the support plate contacts and presses the switch, thus triggering the switch to be energized.

[0035] Preferably, a baffle is fixedly installed on the inner top wall of the water box, and the baffle cooperates with the first drain pipe.

[0036] Since the water flow passing through the water pump has a large impact force, if the water flow directly impacts the filter screen, impurities in the water flow with a volume similar to the mesh size of the filter screen may be stuck in the mesh of the filter screen under the action of the impact force, resulting in the blockage of the filter screen. Therefore, by installing a baffle on the top wall of the water box, the water flow can be prevented from directly impacting the filter screen, and the water flow impacts the baffle and then freely falls along the baffle, thereby reducing the water flow rate and playing a role in preventing the filter screen from being blocked.

[0037] Preferably, the second drain pipe is vertically and fixedly installed on the inner side wall of the pool body.

[0038] Since the top end of the second drain pipe is higher than the liquid level, the liquid level in the second drain pipe can at most be flush with the liquid level in the pool body. Therefore, it can prevent the wastewater in the pool body from flowing back into the water box, playing a role in preventing the inner wall of the filter screen from being blocked.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. During the working process, the first motor is started, and the water pump is driven to operate by the first motor. Since the water inlet of the water pump is connected to the top of the pool body and the suction force of the water pump is large, when the bubble is about to float to the water surface, the water and the bubble around the bubble will be sucked into the water pump together, and then flow out from the drain outlet of the water pump and return to the pool body again. Since molecules do random motion ceaselessly, when the bubble enters the wastewater again, the contact probability between ozone in the bubble and the wastewater is increased, so that the wastewater can be fully contacted with ozone, the production amount of ozone is reduced, and the cost is saved.

[0041] 2. During the working process, the second motor drives the conduit to rotate. Since the collection plate is fixedly connected to the conduit, the collection plate also rotates during the rotation of the conduit. When the collection plate rotates, the wastewater in contact with the collection plate enters the diversion trough together with the bubbles. Since the conduit is connected to the water inlet of the water pump, the connection part between the conduit and the diversion trough has a strong suction force, and since the diversion trough is connected to the conduit, the bubble water entering the diversion trough will be sucked into the conduit, so that the bubbles are again introduced into the pool under the action of the water pump. The second motor drives the conduit to rotate rapidly, so the collection plate also rotates rapidly, thus enabling the timely recovery of a large number of bubbles in the water, playing a role in improving the recovery rate.

[0042] 3. When the bubble water enters the water box together with impurities, the water flow impacts the filter screen. At this time, the impurities in the water flow will be filtered by the filter screen. Therefore, the water flow passing through the filter screen is relatively clean, so that there are no particulate impurities in the wastewater returning to the pool, playing a role in preventing the bubbles from adhering to the surface of the impurities and reducing the contact area between the bubbles and the wastewater.

[0054] Please refer to Figures 1 to 6 , the present invention provides an intelligent control medical wastewater treatment system, and the technical solution is as follows:

[0055] An intelligent control medical wastewater treatment system includes:

[0056] A pool body 1, an ozone generator 23, and an ejector 24. The ozone generator 23 and the ejector 24 are both fixedly installed on the outer side wall of the pool body 1, and the output end of the ozone generator 23 is communicated with the input end of the ejector 24;

[0057] An aeration plate 25, which is horizontally and fixedly installed in the pool body 1, and the output end of the ejector 24 extends into the pool body 1 to a position below the aeration plate 24;

[0058] It further includes:

[0059] The first motor 2 is fixedly installed on the side wall of the pool body 1;

[0060] The water pump 3, the drive shaft of the water pump 3 is fixedly connected to the first output end of the first motor 2, and the water inlet and the drain outlet of the water pump 3 are respectively communicated with the top and the bottom of the pool;

[0061] The collection mechanism, the collection mechanism includes a first support 4 fixedly installed on the inner wall of the pool body 1, a transfer box 5 is fixedly installed on the first support 4, a conduit 6 extending vertically into the transfer box 5 is rotatably installed on the top wall of the transfer box 5, a plurality of collection plates 7 are uniformly fixedly installed at the top end of the conduit 6, a diversion groove 22 communicated with the conduit 6 is formed on the collection plate 7, and a water inlet pipe 8 is fixedly installed between the water box 10 and the water inlet of the water pump 3, and a second motor 9 with an output end extending into the water box 10 and fixedly connected to the conduit 6 is fixedly installed on the bottom wall of the first support 4.

[0062] During the working process, first, the pool body 1 is filled with waste water, and then the ozone generator 23 is started. At this time, the ozone generated in the ozone generator 23 is processed by the ejector 24 and enters the aeration plate 25, and finally is discharged from the air holes of the aeration plate 25. When the mixed gas of ozone and air is discharged from the aeration plate 25, because the density of the bubbles is small, so under the action of buoyancy, the bubbles float upward. During the floating process of the bubbles, the ozone on the outer wall of the bubbles contacts the waste water, and at this time, the ozone can kill the bacteria in the waste water contacted with it, thus realizing oxidation disinfection.

[0063] During the working process, the first motor 2 is started, and the water pump 3 is driven to operate by the first motor 2. Since the water inlet of the water pump 3 is communicated with the top of the pool body 1 and the suction of the water pump 3 is large, when the bubbles are about to float to the water surface, the water and the bubbles around the bubbles will be sucked into the water pump 3 together, and then flow out from the drain outlet of the water pump 3 and return to the pool body 1 again. Because the molecules do perpetual random motion, when the bubbles enter the waste water again, the contact probability between the ozone in the bubbles and the waste water is increased, so that the waste water and the ozone can be fully contacted, the production amount of ozone is reduced, and the cost is saved.

[0064] During the working process, the second motor 9 drives the conduit 6 to rotate. Since the collection plate 7 is fixedly connected to the conduit 6, the collection plate 7 also rotates during the rotation of the conduit 6. When the collection plate 7 rotates, the waste water contacting the collection plate 7 carries the bubbles into the diversion groove 22 together. Since the conduit 6 is communicated with the water inlet of the water pump 3, the part where the conduit 6 is communicated with the diversion groove 22 has strong suction, and the diversion groove 22 is communicated with the conduit 6, so the bubble water entering the diversion groove 22 will be absorbed into the conduit 6, thus realizing the function of introducing the bubbles into the pool body 1 again under the action of the water pump 3.

[0065] The second motor 9 drives the conduit 6 to rotate rapidly, so the collection plate 7 also rotates rapidly, thereby enabling a large number of bubbles in the water to be recycled in a timely manner, playing a role in improving the recycling rate.

[0066] As an implementation manner of the present invention, referring to Figure 5 , the surface of the collection plate 7 is an inclined plane.

[0067] Since the surface of the collection plate 7 is an inclined plane, when the conduit 6 drives the collection plate 7 to rotate, the water in contact with the collection plate 7 is directly shoveled up, reducing the contact area between the collection plate 7 and the water body, playing a role in ensuring the normal rotation of the collection plate 7.

[0068] As an implementation manner of the present invention, referring to Figure 2 , Figure 3 , a water box 10 is fixedly installed on the bottom wall of the first motor 2, a first drain pipe 11 extending into the water box 10 is fixedly installed on the drain outlet of the water pump 3, a second drain pipe 12 extending into the pool body 1 is fixedly installed on the bottom wall of the water box 10, and a barrel-shaped filter screen 13 is provided at a position above the second drain pipe 12 in the water box 10.

[0069] Before the wastewater is treated, the larger impurities in the wastewater will be removed. At this time, smaller impurities remain in the wastewater. Therefore, when the bubbles flow out of the aeration plate 25, the bubbles adhere to the surface of the smaller impurities. As the amount of bubbles on the surface of the impurities increases, the density of the impurities gradually decreases. Therefore, the impurities will float to the water surface. Under the action of the collection plate 7 and the conduit 6, the impurities will enter the diversion groove 22 together with the bubbles and then enter the conduit 6 along the diversion groove 22, and finally pass through the water pump 3 and the first drain pipe 11 and enter the water box 10.

[0070] When the bubble water carries impurities into the water box 10 together, the water flow impacts the filter screen 13. At this time, the impurities in the water flow will be filtered by the filter screen 13. Therefore, the water flow passing through the filter screen 13 is relatively clean, so that there are no granular impurities in the wastewater returned to the pool, playing a role in preventing the bubbles from adhering to the surface of the impurities and causing the contact area between the bubbles and the wastewater to decrease.

[0071] As an implementation manner of the present invention, referring to Figure 3 , a second bracket 14 is vertically rotatably installed in the water box 10, the filter screen 13 is fixedly sleeved on the second bracket 14, and the second output end of the first motor 2 is fixedly connected to the second bracket 14.

[0072] Since the first motor 2 drives the water pump 3 to work during the operation process, the first motor 2 rotates rapidly. Since the second bracket 14 is fixedly connected to the second output end of the first motor 2, the first motor 2 drives the second bracket 14 to rotate rapidly. At this time, the filter screen 13 rotates rapidly together with the second bracket 14. Therefore, the impurities attached to the surface of the filter screen 13 will be separated from the contact with the filter screen 13 under the action of centrifugal force, so that the surface of the filter screen 13 can be kept clean, playing a role of continuous filtration.

[0073] As an implementation manner of the present invention, referring to Figure 3 , a funnel 15 with an upward opening is fixedly installed on the second bracket 14, and the cross-sectional area of the top end of the funnel 15 is larger than the cross-sectional area of the second bracket 14.

[0074] When the impurities are separated from the surface of the filter screen 13 under the action of centrifugal force, the impurities will perform centrifugal motion in the water box 10. When they come into contact with the inner wall of the funnel 15, the impurities will adhere to the inner wall of the funnel 15. Since the second bracket 14 drives the funnel 15 to rotate rapidly, the impurities adhering to the inner wall of the funnel 15 are also subject to a horizontally outward centrifugal force. Since the side wall of the funnel 15 is inclined, when the impurities are subject to a horizontally outward force, the horizontal force also has a component force in the direction along the side wall of the funnel 15 upward. At this time, under the action of the component force, the impurities gradually slide upward along the side of the funnel 15 until they are separated from the contact with the funnel 15. Therefore, the impurities around the filter screen 13 can be transferred in time, playing a role of preventing the effective filtration area of the filter screen 13 from being reduced due to the accumulation of impurities around the filter screen 13.

[0075] As an implementation manner of the present invention, referring to Figure 3 , a sleeve 16 is vertically fixedly installed in the water box 10, the funnel 15 is located inside the sleeve 16, and the cross-sectional area of the sleeve 16 is smaller than the cross-sectional area of the top end of the funnel 15.

[0076] Since the cross-sectional area of the sleeve 16 is smaller than the cross-sectional area of the funnel 15, the impurities flying out from the inner wall of the funnel 15 will splash into the space between the sleeve 16 and the water box 10 under the action of inertia, playing a role of collecting the impurities in the space between the sleeve 16 and the water box 10.

[0077] At the same time, the sleeve 16 is used to separate the impurities from the funnel 15, playing a role of preventing the impurities from accumulating and squeezing the funnel 15, resulting in a large frictional force between the funnel 15 and the impurities and affecting the rotation speed of the funnel 15.

[0078] As an implementation manner of the present invention, referring to Figure 1 、 Figure 2 、 Figure 4, a warning light 17 is fixedly installed on the top wall of the water pump 3, a switch 18 electrically connected to the warning light 17 is fixedly installed on the inner bottom wall of the water box 10, and a triggering mechanism cooperating with the switch 18 is arranged in the water box 10.

[0079] When the impurities between the inner wall of the water box 10 and the sleeve 16 are filled up, the switch 18 is triggered under the action of the triggering mechanism. At this time, the warning light 17 emits light. Since the light of the warning light 17 shines in all directions, the staff can notice it in time, thus playing a role in reminding the staff to clean the impurities in time.

[0080] As an embodiment of the present invention, referring to Figure 3 , Figure 7 , the triggering mechanism includes an annular support plate 19. The support plate 19 is slidably sleeved on the sleeve 16, and the side wall of the support plate 19 is slidably and sealingly connected to the inner wall of the water box 10. A jack is opened on the support plate 19, and a guide rod 26 penetrating through the jack is vertically and fixedly installed on the inner bottom wall of the water box 10. The support plate 19 is made of a magnetic material, and a magnet 20 mutually repelling the support plate 19 is fixedly installed on the bottom wall of the water box 10.

[0081] Under the combined limiting action of the sleeve 16 and the guide rod 26, the support plate 19 can only move up and down along the sleeve 16 and the guide rod 26 without tilting or flipping, so as to ensure that the support plate can move up and down normally. In the initial state, under the action of the repulsive force between the magnet 20 and the support plate 19, the support plate 19 is located at the top of the sleeve 16. As the impurities on the surface of the support plate 19 increase, the overall weight of the support plate 19 also increases. Therefore, the support plate 19 gradually moves down along the outer wall of the sleeve 16. Since the switch 18 is installed on the inner bottom wall of the water box 10, during the downward movement of the support plate 19, the support plate 19 contacts and presses the switch 18, thus playing a role in triggering the switch 18 to be energized.

[0082] As an embodiment of the present invention, referring to Figure 3 , a baffle 21 is fixedly installed on the inner top wall of the water box 10, and the baffle 21 cooperates with the first drain pipe 11.

[0083] Since the water flow passing through the water pump 3 has a large impact force, if the water flow directly impacts the filter screen 13, impurities in the water flow with a volume similar to the mesh size of the filter screen 13 may be stuck in the mesh of the filter screen 13 under the action of the impact force, resulting in the blockage of the filter screen 13. Therefore, by installing the baffle 21 on the top wall of the water box 10, the water flow can be prevented from directly impacting the filter screen 13, and the water flow impacts the baffle 21 and then freely falls along the baffle 21, thereby reducing the water flow rate and playing a role in preventing the filter screen 13 from being blocked.

[0084] As an embodiment of the present invention, referring to Figure 2, the second drain pipe 12 is vertically and fixedly installed on the inner side wall of the pool body 1.

[0085] Since the top end of the second drain pipe 12 is higher than the liquid level, the liquid level in the second drain pipe 12 can at most be flush with the liquid level in the pool body 1. Therefore, it can prevent the waste water in the pool body 1 from flowing back into the water box 10, and plays a role in preventing the inner wall of the filter screen 13 from being blocked.

[0086] Working principle: During the working process, first fill the pool body 1 with waste water, and then start the ozone generator 23. At this time, the ozone generated in the ozone generator 23 is processed by the ejector 24 and enters the aeration plate 25, and finally is discharged from the air holes of the aeration plate 25. When the mixed gas of ozone and air is discharged from the aeration plate 25, due to the smaller density of the bubbles, the bubbles float upward under the action of buoyancy. During the floating process of the bubbles, the ozone on the outer wall of the bubbles contacts the waste water. At this time, the ozone can kill the bacteria in the waste water it contacts, thus realizing oxidation disinfection.

[0087] During the working process, start the first motor 2, and drive the water pump 3 to operate through the first motor 2. Since the water inlet of the water pump 3 is connected to the top of the pool body 1, and the suction of the water pump 3 is relatively large, when the bubbles are about to float to the water surface, the water and bubbles around the bubbles will be sucked into the water pump 3 together, and then flow out from the drain outlet of the water pump 3 and return to the pool body 1 again. Due to the molecules doing perpetual random motion, when the bubbles enter the waste water again, the contact probability between the ozone in the bubbles and the waste water is increased, so that the waste water can be fully contacted with the ozone, reducing the production amount of ozone and playing a role in saving costs.

[0088] During the working process, the second motor 9 drives the conduit 6 to rotate. Since the collecting plate 7 is fixedly connected to the conduit 6, the collecting plate 7 also rotates during the rotation of the conduit 6. When the collecting plate 7 rotates, the waste water in contact with the collecting plate 7 carries the bubbles into the diversion groove 22 together. Since the conduit 6 is connected to the water inlet of the water pump 3, the connection part between the conduit 6 and the diversion groove 22 has a strong suction force, and the diversion groove 22 is connected to the conduit 6. Therefore, the bubble water entering the diversion groove 22 will be absorbed into the conduit 6, so that the bubbles can be re-introduced into the pool body 1 under the action of the water pump 3.

[0089] The second motor 9 drives the conduit 6 to rotate rapidly, so the collecting plate 7 also rotates rapidly, which can timely recover a large number of bubbles in the water and plays a role in improving the recovery rate.

[0090] Before the wastewater is treated, larger impurities in the wastewater will be removed. At this time, smaller impurities remain in the wastewater. Therefore, when bubbles flow out from the aeration plate 25, the bubbles adhere to the surface of the smaller impurities. As the amount of bubbles on the surface of the impurities increases, the density of the impurities gradually decreases. Therefore, the impurities will float to the water surface. Under the action of the collection plate 7 and the conduit 6, the impurities will enter the diversion groove 22 together with the bubbles and then enter the conduit 6 along the diversion groove 22, and finally pass through the water pump 3 and the first drain pipe 11 and enter the water box 10.

[0091] When the bubble water carries impurities into the water box 10, the water flow impacts the filter screen 13. At this time, the impurities in the water flow will be filtered by the filter screen 13. Therefore, the water flow passing through the filter screen 13 is relatively clean, so that there are no particulate impurities in the wastewater returned to the water tank, which plays a role in preventing the contact area between the bubbles and the wastewater from decreasing due to the bubbles adhering to the surface of the impurities.

[0092] Since the first motor 2 drives the water pump 3 to work during the working process, the first motor 2 rotates rapidly. Since the second bracket 14 is fixedly connected to the second output end of the first motor 2, the first motor 2 drives the second bracket 14 to rotate rapidly. At this time, the filter screen 13 rotates rapidly together with the second bracket 14. Therefore, the impurities adhering to the surface of the filter screen 13 will break away from the contact with the filter screen 13 under the action of centrifugal force, so that the surface of the filter screen 13 can be kept clean, which plays a role in continuous filtration.

[0093] When the impurities break away from the surface of the filter screen 13 under the action of centrifugal force, the impurities will perform centrifugal motion in the water box 10. When they contact the inner wall of the funnel 15, the impurities will adhere to the inner wall of the funnel 15. Since the second bracket 14 drives the funnel 15 to rotate rapidly, the impurities adhering to the inner wall of the funnel 15 are also subjected to a centrifugal force horizontally outward. Since the side wall of the funnel 15 is inclined, when the impurities are subjected to a horizontally outward force, the horizontally directed force also has a component force in the direction along the side wall of the funnel 15 upward. At this time, under the action of the component force, the impurities gradually slide upward along the side of the funnel 15 until they break away from the contact with the funnel 15. Therefore, the impurities around the filter screen 13 can be transferred in time, which plays a role in preventing the effective filtration area of the filter screen 13 from decreasing due to the accumulation of impurities around the filter screen 13.

[0094] Since the cross-sectional area of the sleeve 16 is smaller than the cross-sectional area of the funnel 15, the impurities flying out from the inner wall of the funnel 15 will splash into the space between the sleeve 16 and the water box 10 under the action of inertia, which plays a role in collecting the impurities in the space between the sleeve 16 and the water box 10.

[0095] Meanwhile, the sleeve 16 is used to separate impurities from the funnel 15, preventing impurities from accumulating and squeezing the funnel 15, which may cause a large frictional force between the funnel 15 and the impurities and affect the rotation speed of the funnel 15.

[0096] When the impurities between the inner wall of the water box 10 and the sleeve 16 are full, the switch 18 is triggered under the action of the triggering mechanism. At this time, the warning light 17 emits light. Since the light of the warning light 17 shines in all directions, the staff can notice it in time, thus playing a role in reminding the staff to clean the impurities in time.

[0097] Since the water flow passing through the water pump 3 has a large impact force, if the water flow directly impacts the filter screen 13, impurities in the water flow with a volume similar to the mesh size of the filter screen 13 may get stuck in the mesh of the filter screen 13 under the action of the impact force, resulting in the blockage of the filter screen 13. Therefore, by installing a baffle 21 on the top wall of the water box 10, the water flow can be prevented from directly impacting the filter screen 13, making the water flow impact the baffle 21 and then freely fall along the baffle 21, thereby reducing the water flow rate and playing a role in preventing the filter screen 13 from being blocked.

[0098] Since the top end of the second drain pipe 12 is higher than the liquid level, the liquid level in the second drain pipe 12 can at most be flush with the liquid level in the pool body 1. Therefore, the waste water in the pool body 1 can be prevented from flowing back into the water box 10, playing a role in preventing the inner wall of the filter screen 13 from being blocked.
