Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a medical wastewater disinfection treatment system. Background Art

[0002] Medical wastewater mainly refers to sewage discharged from the hospital's treatment rooms, laboratories, wards, laundries, X-ray rooms and operating rooms. The source and composition of the sewage are very complex, and medical wastewater contains a large number of pathogens. Therefore, medical wastewater needs to undergo a series of disinfection treatment processes and meet the discharge conditions before it can be discharged to avoid pollution to external water bodies.

[0003] At present, the disinfection treatment methods of medical wastewater are divided into chemical treatment and physical treatment. Chemical treatment uses chemical agents to react with the proteins of pathogens in the wastewater to form precipitates, which are then filtered. Physical treatment uses ultraviolet rays to destroy the nucleic acids or proteins of pathogens to kill pathogens.

[0004] However, if ultraviolet irradiation is used directly for disinfection, the turbidity, depth and color of the medical wastewater will reduce the penetration of ultraviolet rays, resulting in poor disinfection effect, which will lead to insufficient disinfection of pathogens in the wastewater and cause subsequent pollution risks.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 8 The present invention provides a technical solution: a medical wastewater disinfection treatment system, including a disinfection tank 1, and also including:

[0034] A disturbance component, used to stir the wastewater in the disinfection tank 1 and make it present a vortex shape;

[0035] A UV lamp 5 is arranged in the sterilizing tank 1, and the UV lamp 5 is located at the axis of the sterilizing tank 1, and forms an ultraviolet irradiation area above the center of the formed vortex;

[0036] At least two drain pipes 3 are connected to the outer wall of the disinfection tank 1 . The two drain pipes 3 are vertically distributed and their horizontal heights are higher than the ultraviolet lamp 5 . A solenoid valve is installed at the water inlet of each drain pipe 3 .

[0037] During the use of the medical wastewater disinfection treatment system, the existing pretreatment system is used to filter the wastewater first to remove impurities in the wastewater in preparation for subsequent ultraviolet irradiation disinfection treatment;

[0038] When the filtered wastewater enters the disinfection tank 1, the disturbance component is first used to stir the wastewater in the disinfection tank 1 to make it present a vortex shape. During this process, the surface of the wastewater will gradually form a concave state with a convex edge. For details, please refer to Figure 3 The dotted line indicates the part, so that the wastewater thickness (lateral depth) at the edge protrusion can be reduced. As the edge wastewater rises, part of it moves up to the drain pipe 3, and then is discharged from the disinfection tank 1 through the drain pipe 3, completing the wastewater discharge process;

[0039] In this process, the upward movement of the wastewater edge height will enter the irradiation area of ​​the ultraviolet lamp 5, and it will be irradiated with ultraviolet rays to achieve the purpose of sterilization and disinfection, and the rotational upward movement of the wastewater is equivalent to completing continuous scanning irradiation in the irradiation area of ​​the ultraviolet rays, thereby improving the disinfection effect, and because the reduction in the thickness of the wastewater allows the ultraviolet rays to completely penetrate the wastewater, the reduction in the thickness of the wastewater can also reduce the effect of the wastewater color on the penetration of ultraviolet rays, further ensuring the disinfection effect on pathogens in the wastewater;

[0040] Since the composition of medical wastewater is relatively complex, including drug residues, disinfectants, blood and other organic matter, these factors may cause the wastewater to have different colors, and the depth of the wastewater color directly reflects the impact on the ultraviolet penetration ability. The darker the color, the stronger the blocking of ultraviolet rays. On the contrary, the lighter the color, the weaker the blocking of ultraviolet rays. The depth of the color of the liquid is related to the depth of the liquid. In the above process, the influence of the liquid color is reduced by reducing the lateral thickness of the wastewater. When encountering a darker color, a lighter lateral thickness is required to avoid the influence of its color on the irradiation of the ultraviolet lamp 5.

[0041] Therefore, by setting at least two drainage pipes 3, each drainage pipe 3 is equipped with a solenoid valve at its water inlet, so that the height of the drainage pipe 3 can be controlled. Then, when the water inlet of the drainage pipe 3 becomes higher, the stirring force of the disturbance component can be increased to make the liquid level difference of the vortex higher, so that the edge liquid level of the wastewater can move up to the height of the drainage pipe 3. Figure 3 , a higher liquid level difference of the vortex means a lower wastewater thickness at the edge protrusion, thereby further avoiding the influence of wastewater color on the disinfection effect of the ultraviolet lamp 5;

[0042] In this way, by controlling the opening height of the discharge pipe 3 and the stirring amplitude of the disturbance component, wastewater of different depths and colors can be irradiated and disinfected, ensuring the penetration ability of ultraviolet rays and improving the disinfection effect on pathogens in the wastewater.

[0043] In one of the more preferred embodiments, an implementation of a disturbance component is provided, which can be specifically referred to in Figure 3 and Figure 7 ;

[0044] The disturbance component includes a ventilation box 9 which is rotatably installed at the bottom of the disinfection tank 1 by installing an empty pipe 14, and a servo motor for driving the installed empty pipe 14 to rotate is installed at the bottom of the disinfection tank 1, fan plates 18 are fixed to the outer walls on both sides of the ventilation box 9, and a sewer pipe 4 which is coaxially arranged with the installed empty pipe 14 is fixed to the top of the ventilation box 9, and a purple lamp 5 is wrapped and fixed on the outer wall of the sewer pipe 4.

[0045] During disturbance, the servo motor drives the installed empty pipe 14 to rotate, thereby driving the ventilation box 9 and the sewer pipe 4 to rotate together. The wastewater is stirred into a vortex shape under the manipulation of the fan plate 18. At the same time, the rotation of the sewer pipe 4 also causes the ultraviolet lamp 5 to irradiate in all directions while achieving the purpose of disinfecting the vortex position.

[0046] Embodiment 1 provides an implementation method for adjusting the switch of the drain pipe 3 in the above process. Figure 3 and Figure 7 ;

[0047] A first laser emitter 7 is installed on the outer wall near the bottom of the ultraviolet lamp 5. The first laser emitter 7 emits laser in a horizontal direction, and a corresponding first laser receiver 8 is installed on the inner wall of the disinfection tank 1. The first laser receiver 8 controls the start and stop of the solenoid valves in the two drainage pipes 3 and the rotation speed of the installed empty pipe 14 through electrical signals.

[0048] As can be seen from the previous content, when the liquid level at the edge of the vortex rises, the thickness of the wastewater at the raised edge is lower. Therefore, in the process of generating a vortex and disinfecting it, when the first laser receiver 8 can receive the laser emitted by the first laser transmitter 7, it means that the laser and the ultraviolet light emitted by the ultraviolet lamp 5 can completely penetrate the thickness of the wastewater, so that it can control the electromagnetic valve located in the lower drain pipe 3 to open while ensuring the disinfection effect, so that the wastewater can be discharged from the lower drain pipe 3;

[0049] On the contrary, when the first laser receiver 8 fails to receive or cannot accurately and stably receive the laser emitted by the first laser transmitter 7, it means that the thickness of the wastewater has caused sufficient obstruction to the laser, which means that the irradiation and disinfection effect of the ultraviolet lamp 5 is affected. Therefore, the first laser receiver 8 will control the servo motor to speed up, thereby speeding up the installation of the empty pipe 14 and the ventilation box 9, thereby deepening the concave depth of the vortex, reducing the thickness of the edge wastewater, and raising the liquid level. For details, please refer to Figure 3 The height between h1 and h2 changes, and then when the first laser receiver 8 can receive the laser emitted by the first laser transmitter 7, the first laser receiver 8 controls the electromagnetic valve in the upper drain pipe 3 to open through an electrical signal, so that the vortex edge liquid surface is discharged from the drain pipe 3 at a higher position;

[0050] In this way, the thickness of the edge wastewater is reduced by controlling the concave depth of the vortex, so that the ultraviolet lamp 5 can maintain a sufficient disinfection effect on the edge wastewater. Among them, the drainage pipe 3 is not limited to the two shown in the figure, and multiple groups can be set to provide multiple control methods.

[0051] Embodiment 2 is basically the same as Embodiment 1, except that a second implementation method for adjusting the switch of the drain pipe 3 is provided. Figure 8 ;

[0052] A second laser emitter 20 is installed at the bottom of the ultraviolet lamp 5, and the second laser emitter 20 emits laser in a vertical direction. A corresponding second laser receiver 21 is installed on the top of the ventilation box 9. The second laser receiver 21 controls the start and stop of the solenoid valves in the two drainage pipes 3 and the rotation speed of the installed empty pipe 14 through electrical signals.

[0053] As can be seen from the above, in the first embodiment, the first laser transmitter 7 and the first laser receiver 8 control the selection of the drain pipe 3 by testing the thickness of the vortex edge, and in this embodiment, the control is performed by testing the degree of blocking of the laser by the wastewater between the bottom of the vortex concave surface and the top of the ventilation box 9;

[0054] Since the vortex is generated by centrifugation, if there are still some flocs or suspended matter that have not been cleaned up in the wastewater during pretreatment, these suspended matter will be thrown to the edge under the action of centrifugation, which may block the laser emitted by the first laser emitter 7, thereby affecting the test results. In this embodiment, this effect can be eliminated by testing at the center of the vortex, making the test results more accurate.

[0055] And, similarly, the speed of the installation of the empty pipe 14 is also related to the height of the vortex concave surface, that is, the faster the speed, the lower the concave surface, and the slower the speed, the higher the concave surface. The detection principle is basically the same as that of the first embodiment, so it will not be repeated;

[0056] These two embodiments can be respectively applicable to different wastewater states, and can be selected according to actual conditions, or the two can be used in combination.

[0057] In one of the preferred embodiments, a method of injecting wastewater into the disinfection tank 1 is provided to minimize the impact on the vortex. Figure 3 ;

[0058] A partition plate 6 is fixed to the inner wall of the disinfection tank 1 near the top, and the partition plate 6 divides the disinfection tank 1 into two upper and lower chambers. A water discharge hole is opened in the middle of the partition plate 6, and the top end of the water discharge pipe 4 is rotatably connected to the water discharge hole of the partition plate 6, and a drainage hole is opened on the outer wall of the bottom end of the water discharge pipe 4.

[0059] The wastewater after the previous pretreatment will be discharged into the space above the interlayer plate 6 through the pipeline, and discharged into the space below the disinfection tank 1 through the downpipe 4. Since the drainage hole of the downpipe 4 is located at the bottom of the wastewater, the influence on the vortex can be minimized, while the water volume below the interlayer plate 6 can be maintained.

[0060] Moreover, as the downpipe 4 rotates, waste water will be thrown out from the drainage hole below, thereby speeding up the downward discharge of waste water, avoiding the phenomenon of stuttering when waste water is discharged downward from the downpipe 4, and ensuring the smoothness of the discharge.

[0061] In one of the more preferred embodiments, an aeration disinfection implementation is provided, which can be specifically referred to in Figure 3 and Figure 4 ;

[0062] A piston block 10 is slidably mounted inside the ventilation box 9, a piston rod 11 is fixedly passed through the piston block 10, two ends of the piston rod 11 pass through the two sides of the ventilation box 9 respectively, and are slidably connected with the penetration of the ventilation box 9, the outer walls of both sides of the ventilation box 9 are fixed with fan plates 18, and the fan plates 18 are provided with exhaust channels 19 that can discharge the gas in the ventilation box 9 in one direction, an eccentric ring 13 is fixedly arranged at the inner bottom of the disinfection tank 1, and the two ends of the piston rod 11 passing through the ventilation box 9 can contact the inner ring wall of the eccentric ring 13;

[0063] A fixing plate 16 is fixed to the bottom of the disinfection tank 1, and an installation hollow tube 14 passes through the fixing plate 16. An air supply channel is provided inside the fixing plate 16, and the air supply channel is connected with an external air supply device through an air inlet pipe 17. A one-way valve is installed in the air inlet pipe 17. The installation hollow tube 14 is connected with the inside of the ventilation box 9, and a plurality of ventilation holes 15 are provided on the outer wall of the installation hollow tube 14. When the installation hollow tube 14 rotates, the ventilation holes 15 are intermittently connected with the air supply channel.

[0064] Rollers 12 are rotatably mounted on both ends of the piston rod 11 , and the rollers 12 can roll in contact with the inner ring wall of the eccentric ring 13 .

[0065] From the above content, it can be known that the ventilation box 9 will rotate together with the installation empty pipe 14. During the rotation process, the piston rod 11 will roll along the inner ring wall of the eccentric ring 13, and drive the piston block 10 to slide back and forth in the ventilation box 9, so that the space on both sides of the piston block 10 is continuously expanded and reduced, and then the external ozone is sucked into the ventilation box 9 through the vent 15, the gas transmission channel and the installation empty pipe 14, and then discharged into the wastewater through the exhaust channel 19 in the fan plate 18. In this way, as the ventilation box 9 continues to rotate, ozone can be continuously discharged into the wastewater, and the pathogens in the wastewater can be further disinfected with ozone.

[0066] Moreover, it is worth mentioning that due to the centrifugal effect of the vortex, the ozone bubbles in the water can be torn into small bubbles, which can further increase its contact area with the wastewater and improve the sterilization effect. In addition, since it floats up from the edge, the increase in the liquid level at the edge of the vortex can extend its floating distance and increase its contact time with the wastewater. At the same time, ultraviolet irradiation at the edge of the vortex can promote ozone decomposition to produce hydroxyl free radicals, so that the free radicals can efficiently and non-selectively decompose organic matter in the water, including difficult-to-degrade pollutants. In this way, a more advanced oxidation disinfection treatment process is provided by combining ultraviolet irradiation with ozone disinfection, which makes the disinfection effect of the medical wastewater better.

[0067] In one of the more preferred embodiments, it further comprises a filter part 2, in which a filter assembly is provided, and the waste water filtered in the filter part 2 is discharged to the space above the partition plate 6 through a pipeline.

[0068] The filter part 2 and the filter components inside can be filtered using existing filtering methods to remove suspended impurities in the wastewater, thus preparing for subsequent disinfection treatment.

[0069] In one of the more preferred embodiments, a stirring rod 22 is rotatably mounted on the inner top of the sterilizing tank 1, a motor for driving the stirring rod 22 to rotate is mounted on the top of the sterilizing tank 1, and the top of the partition plate 6 is set to be a concave cone.

[0070] See also Figure 3 By installing a stirring rod 22 above the partition plate 6, the waste water above can also form a vortex, which is mainly beneficial to the discharge of water from the sewer pipe 4.

[0071] In one of the more preferred embodiments, a plurality of fan plates 18 are provided, and a gas distribution port communicating with the exhaust passage 19 is opened on the side of each fan plate 18 .

[0072] See also Figure 7 The arrangement of multiple groups of fan plates 18 and the arrangement of gas distribution ports can further increase the contact area between ozone and wastewater when ozone is introduced, thereby avoiding the occurrence of large bubbles.

[0073] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
