A filter screen is provided inside the wastewater recovery pool, and the filter screen isolates the static area inside the wastewater recovery pool. The water outlet of the wastewater recovery pool is connected to the wastewater treatment pool through a connecting pipe; an impermeable layer is provided on the inner wall of the wastewater treatment pool, and a regulation area, an acidification area, a biochemical area, a sedimentation area and a water purification area are sequentially provided on one side of the connecting pipe, an infrared generator is provided in the regulation area, and a combined filler is provided in the acidification area and the biochemical area, and the combined filler is composed of a frame and a biofilm bundle.

[0004] The above-mentioned equipment has certain deficiencies when performing medical wastewater treatment operations. When adding chemical agents, traditional equipment needs to set up multiple reaction sedimentation water tanks in sequence. The sedimentation tanks occupy a large area. The setting of multiple sedimentation tanks increases the equipment's demand for space, and manual dosing reduces its work efficiency; secondly, when the equipment's pipeline structure performs dosing operations, it is limited by liquid flow and space in the pipeline, so that the medical wastewater and the chemical agents cannot be fully mixed, thereby reducing the use effect of the chemical agents and having no auxiliary mixing structure; at the same time, when the equipment's pipeline structure performs dosing operations, it is affected by the length of the pipeline itself, and the medical wastewater and the chemical agents are excluded when they are not fully reacted, thereby reducing the effect of its pipeline dosing operations and having no extended reaction structure. Summary of the invention

[0005] The purpose of the present invention is to provide a medical wastewater treatment device which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. When adding chemical agents, traditional equipment needs to set up multiple reaction sedimentation water tanks in sequence. The sedimentation tanks occupy a large area. The setting of multiple sedimentation tanks increases the space demand of the equipment, and manual dosing reduces its work efficiency;

[0008] 2. Secondly, when the equipment pipeline structure performs the dosing operation, the medical wastewater and the chemical agents cannot be fully mixed due to the limitation of liquid flow and space in the pipeline, thus reducing the use effect of the chemical agents and having no auxiliary mixing structure;

[0009] 3. At the same time, when the equipment's pipeline structure is performing dosing operations, affected by the length of the pipeline itself, the medical wastewater is discharged before it fully reacts with the chemical agent, thereby reducing the effect of its pipeline dosing operation and not having an extended reaction structure.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] A medical wastewater treatment device comprises a sedimentation tank and a filter, wherein the filter is fixedly mounted on one side of the sedimentation tank, a filter box and a sedimentation box are sequentially arranged on the other side of the sedimentation tank, the filter box and the sedimentation box are through-connected, a UV sterilizer and an ozone generator are sequentially arranged on the output end of the filter, the filter box, the sedimentation box, the sedimentation tank, the filter, the UV sterilizer and the ozone generator are all connected by pipelines, and a plurality of groups of tube body dosing devices are arranged on the surface of the pipeline; the tube body dosing device comprises a mixer, a metering pump and a liquid medicine tank, the liquid medicine tank is fixedly mounted on the feed end of the metering pump, and the mixer is fixedly mounted on the discharge end of the metering pump.

[0012] As a further technical solution of the present invention, a PH electrode is arranged between the two groups of tube body dosing devices, and several groups of pump bodies are arranged at the connection of the pipeline. A water inlet pipe is arranged at one end of the filter box, and a water outlet pipe is arranged at one end of the ozone generator.

Secondly, the setting of the tube body dosing device can add neutralizers, coagulants and disinfectants to the medical waste water through the pipeline, thereby reducing the number of sedimentation tanks used and reducing the occupied area of ​​the wastewater treatment equipment.

[0013] As a further technical solution of the present invention, a mixing tank and a reactor are provided inside the mixer. The mixing tank is arranged on one side of the reactor, and the mixing tank and the reactor are connected through each other. By utilizing the setting of the mixing tank, the medical waste water and the chemical agent can be fully reacted after the tube body applicator completes the chemical agent adding operation. At the same time, the setting of the reactor can extend the flow time of the medical waste water and the chemical agent after mixing, so that the medical waste water and the chemical agent can be fully reacted, thereby improving the medical waste water treatment effect.

[0015] As a further technical solution of the present invention, the disperser is a hollow spherical structure as a whole, and a plurality of groups of circular holes are radially arranged on the outer surface of the disperser. When the chemical agent is introduced into the disperser, the radial circular holes on its surface are utilized to make the drug liquid radially ejected, so that it can be mixed with the medical waste water more fully.

[0016] As a further technical solution of the present invention, the mixer includes several groups of spoiler disks, which are arranged side by side, with mixing gaps between the groups of spoiler disks, and the groups of spoiler disks are connected and fixed by partition columns.

Secondly, the staggered circular notches allow the liquid to contact the surface of the spoiler after flowing out of the circular notches, so that the medical waste water and the chemical agents can be better mixed.

[0018] As a further technical solution of the present invention, an outer spiral tube, a middle spiral tube and an inner spiral tube are fixedly installed inside the reactor, the outer spiral tube is sleeved on the outer side of the middle spiral tube, the inner spiral tube is sleeved on the inner side of the middle spiral tube, a drain pipe is installed in the middle of the inner spiral tube, the outer spiral tube, the middle spiral tube and the inner spiral tube are all connected through a series joint, and a three-layer spiral tubular structure is formed by the outer spiral tube, the middle spiral tube and the inner spiral tube to make full use of the internal space of the reactor. When medical waste water and chemical agents enter into the reactor, the flow time of the medical waste water and chemical agents can be extended in a smaller space, so that the medical waste water and chemical agents can fully react.

[0019] As a further technical solution of the present invention, several groups of serpentine tubes are fixedly installed inside the reactor, and the several groups of serpentine tubes are connected and fixed by connecting frames, and the several groups of serpentine tubes are connected by series joint pipe bodies. By utilizing the combination of several groups of serpentine tubes, medical waste water and chemicals can flow in the reactor for a long time, extending the reaction time of medical waste water and chemicals and allowing them to react fully.

[0020] As a further technical solution of the present invention, the surface of the connecting frame is provided with a plurality of strip-shaped notches, a discharge pipe is fixedly installed at one end of the reactor, and the plurality of strip-shaped notches of the connecting frame can play an auxiliary fixing role in the installation of the serpentine pipe.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting a pipe dosing device, the medical wastewater treatment equipment has a pipeline dosing structure when in use, thereby reducing the use of sedimentation tanks. Unlike other equipment that sets reaction sedimentation water tanks in sequence when adding chemical agents, the system needs to be equipped with multiple sedimentation tanks. When this equipment performs physical and chemical treatment and adds agents, the agents are added into the pipeline, and then only one sedimentation water tank is set, which reduces the equipment's space requirements to a certain extent and reduces the equipment's footprint;

[0023] During operation, the chemical agents in the medicine tank are automatically discharged by a metering pump. The metering pump is a fully automatic diaphragm signal metering pump, which can automatically add a certain amount of chemical agents according to the water quality to ensure the continuous and stable operation of the physicochemical treatment unit and improve its water treatment efficiency. The chemical agents are transported to the disperser through the feed pipe, and the chemical agents are diffused and released through the disperser. The medical waste water is transported to the inside of the mixing tank by the dosing pipe, so that the medical waste water is mixed and contacted with the chemical agents. After a series of treatments such as the filter box, the sedimentation box, the sedimentation tank, the filter, the UV sterilizer and the ozone generator, the harmful substances in the medical waste water are removed and discharged through the outlet pipe of the ozone generator. Secondly, the setting of the tube body dosing device can add neutralizers, coagulants and disinfectants to the medical waste water through the pipeline during the corresponding treatment steps, thereby reducing the number of sedimentation tanks used and reducing the occupied area of ​​​​the wastewater treatment equipment.

[0024] 2. By setting up a mixer, when the medical wastewater treatment equipment is used, the use of the tube dosing device is optimized, so that the medical wastewater and chemical agents can be fully integrated during the short-distance movement process to improve the medical wastewater treatment effect;

[0025] During use, when the chemical agent is introduced into the disperser, the radial circular holes on its surface are used to make the liquid medicine radially ejected, so that it is mixed with the medical waste water more fully, and the chemical agent is diffused and released through the disperser, and then the medical waste water is transported to the inside of the mixing tank by the feed pipe, so that the medical waste water and the chemical agent are mixed and contacted, and a plurality of groups of spoiler disks are used to form a mixer. After the medical waste water and the chemical agent pass through the spoiler disk, the medical waste water and the chemical agent are fully mixed in a short distance, and the spoiler disk and the mixing tank are connected and fixed by a sealing ring to prevent the liquid from flowing out of the gap between the spoiler disk and the mixing tank. Secondly, the circular notches are staggered so that the liquid contacts the surface of the spoiler disk after flowing out of the circular notches, so that the medical waste water and the chemical agent can be better mixed.

[0026] 3. By setting up a reactor, when the medical wastewater treatment equipment is used, it has a coil-type auxiliary material delivery structure, which can effectively extend the delivery time of medical wastewater and chemical agents, so that the medical wastewater and chemical agents can fully react;

[0027] During operation, the reactor has two usage states. In state one, the interior of the reactor is a spiral tubular structure, and the three-layer spiral tubular structure is composed of an outer spiral tube, a middle spiral tube and an inner spiral tube, which fully utilizes the internal space of the reactor. When medical waste water and chemical agents enter the reactor, the flow time of the medical waste water and chemical agents can be extended in a smaller space, so that the medical waste water and chemical agents can fully react, and the problem of the hollow structure in the middle of the spiral tube is optimized. In state two, the interior of the reactor is a serpentine tubular structure, and several groups of strip grooves of the connecting frame can be used to assist in fixing the installation of the serpentine tube. Several groups of serpentine tubes are connected in series with each other using series joints, so that the medical waste water and chemical agents can flow in the reactor for a long time and fully react.

[0037] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0038] like Figure 1 As shown, a medical wastewater treatment equipment includes a sedimentation tank 8 and a filter 9, the filter 9 is fixedly installed on one side of the sedimentation tank 8, and a filter box 1 and a sedimentation box 2 are sequentially arranged on the other side of the sedimentation tank 8, the filter box 1 and the sedimentation box 2 are through-connected, and a UV sterilizer 10 and an ozone generator 11 are sequentially installed at the output end of the filter 9, the filter box 1, the sedimentation box 2, the sedimentation tank 8, the filter 9, the UV sterilizer 10 and the ozone generator 11 are all connected by a pipeline 32, and a plurality of groups of tube body dosing devices 3 are arranged on the surface of the pipeline 32; the tube body dosing device 3 includes a mixer 5, a metering pump 6 and a liquid medicine tank 7, the liquid medicine tank 7 is fixedly installed at the feed end of the metering pump 6, and the mixer 5 is fixedly installed at the discharge end of the metering pump 6.

[0039] To solve the problem of adding reagents to the processing equipment, such as Figure 1As shown, a PH electrode 4 is arranged between the two groups of tube body applicators 3, a plurality of pump bodies 12 are arranged at the connection of the pipeline 32, a water inlet pipe is arranged at one end of the filter box 1, and a water outlet pipe is arranged at one end of the ozone generator 11. The medical waste water is introduced into the filter box 1 by means of the water inlet pipe, and after a series of treatments by the filter box 1, the sedimentation box 2, the sedimentation tank 8, the filter 9, the UV sterilizer 10 and the ozone generator 11, the harmful substances in the medical waste water are removed and discharged through the water outlet pipe of the ozone generator 11. Secondly, the setting of the tube body applicator 3 can add a neutralizer, a coagulant and a disinfectant to the medical waste water through the pipeline 32, thereby reducing the number of sedimentation tanks 8 used and reducing the occupied area of ​​the wastewater treatment equipment.

[0040] A mixing tank 18 and a reactor 17 are provided inside the mixer 5. The mixing tank 18 is arranged on one side of the reactor 17. The mixing tank 18 and the reactor 17 are connected through each other. By using the setting of the mixing tank 18, the medical waste water and the chemical agent can be fully reacted after the tube body applicator 3 completes the chemical agent adding operation. At the same time, the setting of the reactor 17 can extend the flow time of the medical waste water and the chemical agent after mixing, so that the medical waste water and the chemical agent can fully react, thereby improving the medical waste water treatment effect.

[0041] To improve the effect of dosing in the pipeline of the treatment equipment, such as Figure 2 As shown, a mixer 15 and a disperser 19 are provided inside the mixing tank 18, and the mixer 15 is arranged on one side of the disperser 19. A feed pipe 13 is installed at one end of the mixing tank 18, and a dosing pipe 14 is provided at one end of the disperser 19. The chemical agent in the liquid medicine tank 7 is automatically discharged by the metering pump 6, so that the chemical agent is transported to the disperser 19 through the feed pipe 13, and the chemical agent is diffused and released through the disperser 19, and then the medical waste water is transported to the inside of the mixing tank 18 by the dosing pipe 14, so that the medical waste water is mixed and contacted with the chemical agent. The metering pump 6 is a fully automatic diaphragm signal metering pump 6, which can automatically add a certain amount of chemical agent according to the water quality to ensure the continuous and stable operation of the physicochemical treatment unit.

[0042] like Figure 2 As shown, the disperser 19 is a hollow spherical structure as a whole, and the outer surface of the disperser 19 is radially provided with a plurality of groups of circular holes. When the chemical agent is introduced into the disperser 19, the radial circular holes on the surface are utilized to make the chemical liquid radially ejected, so that it can be mixed with the medical waste water more fully.

[0043] To improve the effect of dosing in the pipeline of the treatment equipment, such as Figure 4As shown, the mixer 15 includes a plurality of groups of spoiler disks 25, which are arranged side by side, with mixing gaps between the plurality of groups of spoiler disks 25, and the plurality of groups of spoiler disks 25 are connected and fixed by separators 28. The mixer 15 is composed of the plurality of groups of spoiler disks 25, so that the medical waste water and the chemical agents are fully mixed within a short distance after passing through the spoiler disks 25.

[0044] like Figure 4 As shown, the outer surface of the spoiler 25 is provided with a plurality of groups of circular notches 27, and the circular notches 27 between the plurality of groups of spoiler disks 25 are staggered. The outer surfaces of the plurality of groups of spoiler disks 25 are fixedly installed with sealing rings 26, and the sealing rings 26 are used to connect and fix the spoiler 25 and the mixing tank 18 to prevent the liquid from flowing out of the gap between the spoiler 25 and the mixing tank 18. Secondly, the staggered circular notches 27 allow the liquid to contact the surface of the spoiler 25 after flowing out of the circular notches 27, so that the medical waste water and the chemical agents can be better mixed.

[0045] To extend the reaction time of wastewater treatment, Figure 3 As shown, an outer spiral tube 20, a middle spiral tube 21 and an inner spiral tube 22 are fixedly installed inside the reactor 17. The outer spiral tube 20 is sleeved on the outer side of the middle spiral tube 21, and the inner spiral tube 22 is sleeved on the inner side of the middle spiral tube 21. A drain pipe 23 is installed in the middle of the inner spiral tube 22. The outer spiral tube 20, the middle spiral tube 21 and the inner spiral tube 22 are all connected through a series joint 24. The outer spiral tube 20, the middle spiral tube 21 and the inner spiral tube 22 form a three-layer spiral tubular structure, which fully utilizes the internal space of the reactor 17. When medical waste water and chemical agents enter into the reactor 17, the flow time of the medical waste water and chemical agents can be extended in a smaller space, so that the medical waste water and chemical agents can fully react.

[0046] like Figure 5 and 6 As shown, a plurality of groups of serpentine tubes 30 are fixedly installed inside the reactor 17, and the plurality of groups of serpentine tubes 30 are connected and fixed by connecting frames 29, and the plurality of groups of serpentine tubes 30 are connected by series joints 24. By utilizing the combination of the plurality of groups of serpentine tubes 30, medical waste water and chemical agents can flow in the reactor 17 for a long time, thereby extending the reaction time of the medical waste water and chemical agents and allowing them to react fully.

[0047] like Figure 7 As shown, the surface of the connecting frame 29 is provided with a plurality of strip-shaped notches 31 , and a discharge pipe 16 is fixedly installed at one end of the reactor 17 . The plurality of strip-shaped notches 31 of the connecting frame 29 can play an auxiliary fixing role in the installation of the serpentine pipe 30 .

[0048] When using, traditional equipment needs to set up multiple reaction sedimentation water tanks in sequence when adding chemical agents. The sedimentation tanks occupy a large area. The setting of multiple sedimentation tanks increases the space demand of the equipment, and manual dosing reduces its work efficiency.

[0049] To this end, by setting a pipe body dosing device 3, when the medical wastewater treatment equipment is used, it has a pipeline dosing structure, thereby reducing the use of the sedimentation tank 2. Unlike other equipment, when adding chemical agents, reaction sedimentation water tanks are set in sequence, and the system needs to be equipped with multiple sedimentation tanks 2, when the equipment performs physical and chemical treatment and adds agents, the agents are added into the pipeline 32, and then only one sedimentation water tank is set, which reduces the space demand of the equipment to a certain extent and reduces the equipment footprint;

[0050] During operation, the chemical agent in the liquid medicine tank 7 is automatically discharged by the metering pump 6. The metering pump 6 is a fully automatic diaphragm signal metering pump 6. According to the water quality, a certain amount of chemical agents can be automatically added to ensure the continuous and stable operation of the physical and chemical treatment unit, and its water treatment efficiency is improved, so that the chemical agent is transported to the disperser 19 through the feed pipe 13, and the chemical agent is diffused and released through the disperser 19, and then the medical waste water is transported to the inside of the mixing tank 18 by the dosing pipe 14, so that the medical waste water is mixed with the chemical agent. After a series of treatments by the filter box 1, the sedimentation box 2, the sedimentation tank 8, the filter 9, the UV sterilizer 10 and the ozone generator 11, the harmful substances in the medical waste water are removed and discharged through the outlet pipe of the ozone generator 11. Secondly, the setting of the tube body dosing device 3 can add neutralizers, coagulants and disinfectants to the medical waste water through the pipeline 32 in the corresponding treatment steps, thereby reducing the number of sedimentation tanks 8 used and reducing the occupied area of ​​the wastewater treatment equipment;

[0051] Secondly, when the equipment pipeline structure is used for dosing, the medical wastewater and the chemical agents cannot be fully mixed due to the limitation of liquid flow and space in the pipeline, thus reducing the use effect of the chemical agents and having no auxiliary mixing structure.

[0052] To this end, by setting the mixer 5, when the medical wastewater treatment equipment is used, the use of the tube body applicator 3 is optimized, so that the medical wastewater and the chemical agent can be fully integrated during the short-distance movement process to improve the medical wastewater treatment effect;

[0053] During use, when the chemical agent is introduced into the disperser 19, the radial circular holes on the surface of the disperser 19 are used to make the liquid medicine radially ejected, so that it is mixed more fully with the medical waste water, and the chemical agent is diffused and released through the disperser 19, and then the medical waste water is transported to the inside of the mixing tank 18 by the feed pipe 13, so that the medical waste water and the chemical agent are mixed and contacted, and a plurality of groups of spoiler disks 25 are used to form the mixer 15. After the medical waste water and the chemical agent pass through the spoiler disk 25, the medical waste water and the chemical agent are fully mixed in a short distance, and the sealing ring 26 is used to connect and fix the spoiler disk 25 and the mixing tank 18 to prevent the liquid from flowing out of the gap between the spoiler disk 25 and the mixing tank 18. Secondly, the circular notches 27 are arranged in an offset manner so that the liquid contacts the surface of the spoiler disk 25 after flowing out of the circular notches 27, so that the medical waste water and the chemical agent can be better mixed;

[0054] At the same time, when the equipment pipeline structure performs the dosing operation, affected by the length of the pipeline itself, the medical wastewater is discharged before the chemical agent has fully reacted, thereby reducing the effect of the pipeline dosing operation and not having an extended reaction structure;

[0055] To this end, by setting the reactor 17, when the medical wastewater treatment equipment is used, it has a coil-type auxiliary material delivery structure, which can effectively extend the delivery time of medical wastewater and chemical agents, so that the medical wastewater and chemical agents can fully react;

[0056] During operation, the reactor 17 has two usage states. In state one, the interior of the reactor 17 is a spiral tubular structure, and the three-layer spiral tubular structure is composed of an outer spiral tube 20, a middle spiral tube 21 and an inner spiral tube 22, so that the internal space of the reactor 17 is fully utilized. When medical waste water and chemical agents enter the interior of the reactor 17, the flow time of the medical waste water and chemical agents can be extended in a smaller space, so that the medical waste water and chemical agents can fully react, and the problem of the hollow structure in the middle of the spiral tube is optimized. In state two, the interior of the reactor 17 is a serpentine tube 30-like structure. The several groups of strip notches 31 of the connecting frame 29 can play an auxiliary fixing role in the installation of the serpentine tube 30. The several groups of serpentine tubes 30 are connected in series with each other using the series joint 24, so that the medical waste water and chemical agents can flow in the reactor 17 for a long time and react fully.
