Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment containing organic matter, specifically an integrated water treatment device. Background Technology

[0002] Wastewater from pharmaceutical, pesticide, and other laboratory or small-scale production processes contains a large amount of organic matter. Wastewater treatment must adequately consider both sterilization and organic matter removal. Since wastewater often contains salt, the degradation of organic matter frequently relies on advanced oxidation technologies, which utilize the generation of highly oxidizing free radicals. However, this technology is sensitive to salinity; its degradation capacity is significantly reduced when salinity is below 4%. Therefore, treating wastewater with high organic matter content and salinity presents challenges such as complex procedures, time-consuming processes, and high costs. Utility Model Content

[0003] The purpose of this invention is to provide an integrated water treatment device that can efficiently decompose organic matter in wastewater, thoroughly sterilize and disinfect, and achieve excellent treatment results.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An integrated water treatment device includes a tank. The bottom of the tank is provided with a dosing pipe, an air inlet connector, and a water outlet connector. The tank is also connected to an inlet pipe for introducing wastewater. A microbubble generator and an ozone generator are connected in sequence to the air inlet connector. The dosing pipe is connected to a hydrogen peroxide tank. The water outlet connector is connected to a main water inlet pipe. Multiple ultraviolet processors are connected in series on the main water inlet pipe.

[0006] A transparent observation tube is installed on the main water inlet pipe.

[0007] The tank is a vertically extending cylindrical stainless steel tank. The top of the tank has a mouth, and above the mouth is a lid that can be sealed and closed. The lid is arched, and above the lid is an arched pressure frame. A hinge seat is located at the center of the top of the lid. The middle part of the pressure frame is rotatably connected to the hinge frame. The top of the tank has an angle frame that is hinged to one end of the pressure frame. On the upper part of the side wall of the tank, opposite to the angle frame, there is a bearing seat. A swing shaft is rotatably connected to the bearing seat. A screw is fixed in the center of the swing shaft and vertically connected to it. A clamping handle is threaded onto the top of the screw. The pressure frame has an H-shaped opening at one end near the bearing seat, through which the screw passes. The screw can pass through the H-shaped opening and is pressed against the top of the H-shaped opening by the clamping handle.

[0008] The water inlet pipe passes through the tank wall from the top of the tank. After passing through the top of the tank, the water inlet pipe bends downward at a 90-degree angle and extends downward. The opening of the water inlet pipe is located in the middle of the tank, so as to realize the feeding from the middle.

[0009] An overflow pipe is connected to the top of the tank in a sealed manner. The overflow pipe is horizontally positioned, and three transparent observation ports are arranged sequentially along the height of the tank.

[0010] The ultraviolet processor includes a processing tube and a lamp of appropriate length. The lamp is an ultraviolet lamp with a wavelength of 185 micrometers. The lamp is centrally located inside the processing tube, and there is a gap between the lamp and the wall of the processing tube for water flow.

[0011] There are 6 ultraviolet processors. Each processing tube has an upper tube head and a lower tube head at both ends. The upper tube head and the lower tube head are respectively located above and below the processing tube. The upper tube head is used to connect the water flow, and the lower tube head is used to discharge the water flow. The lower tube head and the upper tube head of adjacent ultraviolet processors are sealed and connected to form a series structure.

[0012] The processing tube has threaded openings at both ends with reduced diameter. A sealing cap is screwed onto the threaded opening. The diameter of the lamp tube is adapted to the inner diameter of the threaded opening.

[0013] The ultraviolet processor is divided into an equal number of first and second columns. The lower end of the first column of processing tubes is connected to an S-shaped serial connector. The lower end of the second column of processing tubes is connected to a main water distribution pipe via a pipeline. The main water distribution pipe is centrally located between the first and second columns. Below the main water distribution pipe, multiple membrane processors are located between the first and second columns. The membrane processors are installed vertically. The top of each membrane processor is connected to a water distribution pipe that communicates with the main water distribution pipe. The bottom of each membrane processor is connected to a concentrate outlet pipe. A purified water pipe is connected to the side wall of each membrane processor. A horizontally extending water collection pipe is located on one side of each membrane processor. All purified water pipes are connected to the water collection pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This device can degrade and disinfect wastewater containing organic matter. After entering the tank, the wastewater, containing organic matter, comes into full contact with ozone microbubbles to dissolve it, and mixes with hydrogen peroxide. The ozone- and hydrogen peroxide-containing wastewater is then introduced into the ultraviolet (UV) processor through the bottom of the tank. When the ozone comes into contact with UV light, the UV light oxidizes the ozone into oxygen free radicals. Simultaneously, the UV light reacts with hydrogen peroxide to generate hydroxyl radicals, degrading the organic matter and providing excellent sterilization. The degradation rate is very high, and with six UV processors connected in series, near-complete degradation can be achieved, thus removing organic matter. Attached Figure Description

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] This integrated water treatment device includes a tank 1, an ultraviolet processor, and a membrane processor 27 connected in sequence via pipelines.

[0026] The tank 1 is a vertically extending cylindrical stainless steel tank. The bottom of the tank 1 has an arc-shaped base to facilitate the dispersion of microbubbles and allows for downward airflow due to the central depression. Support legs 2 are provided around the perimeter of the tank 1 to elevate its bottom. The top of the tank 1 has a canopy, above which is fitted a lid 3 that can be sealed shut. The lid 3 is arched, and both the canopy and the edges of the lid 3 have outwardly extending annular rings. Combined with a sealing structure (such as a sealing gasket), this enhances the sealing effect after closure. An arched pressure frame 5 is located above the lid 3, and a hinge seat 4 is located at the center of the top of the lid 3. The middle of the pressure frame 5 rotates with the hinge frame. The tank body 1 is connected in a dynamic manner. The top of the tank body 1 is provided with an angled frame 6 that is hinged to one end of the pressure frame 5. The upper part of the side wall of the tank body 1, opposite to the angled frame 6, is provided with a bearing seat 7. A swing shaft 8 is rotatably connected to the bearing seat 7. A screw 9 is fixed in the center of the swing shaft 8 and is vertically connected to it. A clamping handle 10 is threaded onto the top of the screw 9. The pressure frame 5 is provided with an H-shaped opening 11H that passes through it from top to bottom at one end near the bearing seat 7. The screw 9 can pass through the H-shaped opening 11H and is pressed above the H-shaped opening 11H by the clamping handle 10. Rotating the clamping handle 10 can lock the cover 3 in a sealed manner, and after loosening, the locking of the cover 3 can be released by swinging it outward.

[0027] The pressure frame 5 adopts a straight-line extension structure at the H-shaped opening 11H position, which better matches the pressure handle 10.

[0028] The top of the tank body 1 is permeated with a water inlet pipe 12 and an overflow pipe 13 that are sealed to it. The overflow pipe 13 is horizontally set and is used to overflow outward through the overflow pipe 13 when the water level is higher than the overflow pipe 13. The water inlet pipe 12 passes through the top of the tank body 1 and then bends downward at 90 degrees. The opening of the water inlet pipe 12 is located in the middle of the tank body 1 to realize the middle feeding.

[0029] The bottom of the tank 1 is equipped with a dosing pipe 14, an air inlet connector 15, and a water outlet connector 16. The bottom of the pipe is arc-shaped, which also helps to make the center of the tank 1 the lowest point. The water outlet connector 16 is located in the center to facilitate the drainage of liquid. A microbubble generator and an ozone generator are connected sequentially to the air inlet connector 15 in the direction of the air source. The ozone generator is connected to the air path of the microbubble generator, and the gas generated by the ozone generator is delivered to the microbubble generator. The ozone is aerated by the microbubble generator, and the generated microbubbles enter the tank 1, achieving full contact between a large number of ozone microbubbles and water. The dosing pipe 14 penetrates through the bottom of the tank, and the inner end of the dosing pipe 14 is located at the interface of the air inlet connector 15. A hydrogen peroxide tank is connected to the dosing pipe 14 through a pipeline. By adding a small amount of hydrogen peroxide and setting the hydrogen peroxide dosing point near the air inlet connector 15, the hydrogen peroxide is quickly dispersed by microbubbles, so that the water entering the ultraviolet processor carries hydrogen peroxide.

[0030] Three observation ports 17 are sequentially arranged along the height of the tank body 1. Each observation port 17 is made of transparent glass, allowing observation of the interior. The middle observation port 17 is located in the center of the tank body 1. Typically, the first observation port 17 at the top is entirely white, while the middle observation port 17 shows only partial white areas. The observation ports 17 at the bottom are generally clear.

[0031] This tank 1 operates through bottom aeration, middle feeding, and bottom liquid discharge. Microbubbles ensure ample contact with organic matter, improving degradation efficiency. After a large number of ozone microbubbles enter the bottom of the tank, due to their light weight and upward movement, they react thoroughly with the water entering from the middle. The ozone dissolves in the water, and the microbubbles rise and concentrate in the upper half of tank 1, making it visually white and containing abundant microbubbles. The water in the lower half of tank 1, after contacting the ozone microbubbles, dissolves and contains a high concentration of ozone, which is then carried into the UV processor. The reason for not selecting the water with the higher microbubble content at the top is its white color, which is unfavorable for the decomposition of ozone by ultraviolet light; therefore, bottom liquid discharge is chosen to improve the reaction efficiency of ozone and ultraviolet light, thereby increasing the degradation rate.

[0032] The ultraviolet processor and membrane processor 27 are integrated and installed together. In order to make the integration more convenient in terms of structure and space, the ultraviolet processor and membrane processor are integrated and laid out together. Through reasonable space design, they can be used in a compact and convenient manner.

[0033] Structurally, it includes a support frame 31 for mounting and supporting all components. The support frame 31 adopts a portal frame structure. Three processing tubes 18 are fixed on each side of the support frame 31, and there are a total of six processing tubes 18 extending horizontally. The processing tubes 18 can be fixed to the support frame 31 by clamps and fasteners. Each end of the processing tube 18 is provided with a tapered threaded opening 19. A sealing cap 20 is screwed onto the threaded opening 19 to seal the threaded openings 19 at both ends. A lamp tube 30 is inserted through the processing tube 18. The lamp tube 30 is an ultraviolet lamp tube with a wavelength of 185 micrometers. The length of the lamp tube 30 is adapted to the length of the processing tube 18. The diameter of the lamp tube 30 is adapted to the inner diameter of the threaded opening 19. The threaded opening 19 constrains the lamp tube 30 in the center of the processing tube 18. One end of the lamp tube 30 is provided with a lamp head with a wire. One of the sealing caps 20 is provided with a round hole for the lamp head and the wire to pass through. The lamp head passes through the round hole and is sealed with the round hole.

[0034] The treatment pipe 18 is provided with an upper pipe head 21 and a lower pipe head 22 near both ends. The upper pipe head 21 and the lower pipe head 22 are respectively located above and below the treatment pipe 18. The upper pipe head 21 is used to connect water, and the lower pipe head 22 is used to discharge water.

[0035] In terms of connection, the processing pipes 18 are set in two columns, with three processing pipes 18 in each column arranged vertically at equal intervals. For ease of description, they are defined as the first column and the second column according to the direction of water flow.

[0036] After the raw water is treated by ozone in tank 1, the clarified water is connected to a gate-shaped main water inlet pipe 23 at the bottom through a flexible plastic water pipe via a water outlet connector 16. The bottom end of the main water inlet pipe 23 is connected to the upper pipe head 21 of the upper treatment pipe 18 in the first column, which is used to connect the water containing high concentration of ozone and a small amount of hydrogen peroxide to the first ultraviolet processor.

[0037] The lower pipe head 22 and upper pipe head 21 of the first column of treatment pipes 18 are connected by flange clamps to realize the series connection of adjacent treatment pipes 18. An S-shaped connecting pipe 25 is connected to the lower pipe head 22 of the first column of treatment pipes 18 at the bottom. The other end of the connecting pipe 25 is connected to the upper pipe head 21 of the upper layer of the second column of treatment pipes 18. The lower pipe head 22 and upper pipe head 21 of the second column of treatment pipes 18 are connected by flange clamps to realize the series connection of adjacent treatment pipes 18. A water distribution main pipe 26 is connected to the lower pipe head 22 of the second column of treatment pipes 18 at the bottom through a pipeline. The pipeline is U-shaped bent so that the water distribution main pipe 26 is centered between the first column and the second column.

[0038] Multiple membrane processors 27 are vertically arranged between the first and second columns. The membrane processors 27 are commonly used and mature in existing technology. Each membrane processor 27 has a branch pipe 28 connected to the main water distribution pipe at its top and a concentrate outlet pipe at its bottom. A collection pipe connected to each concentrate outlet pipe is located below the membrane processor 27 for unified collection and treatment of the concentrate. A purified water pipe is connected to the side wall of each membrane processor 27, and a horizontally extending collection pipe 29 is located on one side of each membrane processor 27. All purified water pipes are connected to the collection pipe 29 to collect the treated purified water. Based on the distribution of the above-mentioned water distribution pipes, water treated in series by the ultraviolet processors is then processed in parallel by multiple membrane processors 27, thereby improving the downstream processing capacity, matching the upstream influent volume, and ultimately achieving concentration and salt separation.

[0039] The final membrane processor 27 stage can be set up or not, depending on the situation. If the membrane processor 27 is not set up, the purified water after disinfection and degradation of organic matter can be directly discharged through the pipeline from the lower pipe head 22 of the second column of treatment pipes 18 at the bottom.

[0040] A transparent observation tube 24 is provided on the main water inlet pipe 23. Based on its transparency, the observation tube 24 can clearly observe whether the water entering the ultraviolet processor is clear. If it is white, the aeration rate needs to be adjusted because the white will hinder the decomposition of ozone by ultraviolet rays, thus affecting the degradation.

[0041] In summary, the above treatment process involves wastewater with high organic content first entering tank 1. After thorough contact and dissolution with ozone microbubbles, and with the addition of a small amount of hydrogen peroxide, the clarified ozone- and hydrogen peroxide-containing wastewater is introduced into the ultraviolet (UV) processor at the bottom of tank 1. This wastewater is then treated by six UV lamps (30) connected in series to reduce the concentration of organic matter. The UV lamps have a wavelength of 185 micrometers and use long tubes (30) that run through the entire treatment tube (18). Water flows between the tubes (30) and the tube wall. When ozone comes into contact with UV light, the UV light oxidizes the ozone into oxygen free radicals. Simultaneously, the UV light reacts with hydrogen peroxide to generate hydroxyl radicals, degrading the organic matter and providing excellent sterilization. The degradation rate is very high, reducing DOC from 500-600 to over 90%. With the six UV processors connected in series, near-complete degradation is achieved, thus realizing the removal of organic matter.

[0042] Finally, the water that has undergone sterilization and degradation can be collected directly or treated with a membrane to separate the salt.

[0043] This device achieves advanced oxidation using ozone and ultraviolet light, and is unaffected by salinity. Conventional advanced oxidation processes are all affected by salinity; almost all advanced oxidation processes cannot function at salinity levels above 4%. However, this method is not limited by salinity and has a wide range of applications.
