[0001] This application relates to the field of drinking water treatment technology, and more particularly to a drinking water treatment system. Background Technology
[0002] In recent years, my country has faced severe water pollution problems, with an increasing number of harmful substances detected in water sources, posing a serious challenge to drinking water safety. In some rural areas, residents have been drinking water with high arsenic, high fluoride, or other contaminated conditions for extended periods, leading to various related diseases and seriously threatening their health. Therefore, people's requirements for drinking water are becoming increasingly stringent and demanding.
[0003] Drinking water is municipal tap water that has undergone advanced purification through a special process. It is then mixed with ozone, sealed in containers without any additives, and sterilized with ultraviolet light to meet national drinking water standards. Finally, it is delivered directly to each drinking point via variable frequency pumps and independent food-grade pipelines, ensuring safe and directly drinkable water. Therefore, meeting the functional requirements of drinking water is crucial.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0051] As described in the background section, traditional drinking water treatment mainly employs conventional multi-stage sedimentation, sand filtration, or activated carbon filtration methods, but these methods suffer from problems such as large footprint, high cost, and secondary pollution.
[0052] To address the aforementioned technical problems, this application provides a drinking water treatment system comprising a pretreatment device, an ultrafiltration device, and a disinfection device. The outlet of the pretreatment device is connected to the inlet of the ultrafiltration device via an inlet connector. The outlet of the ultrafiltration device is connected to the inlet of the disinfection device via a disinfection pipeline. The outlet of the disinfection device is connected to the user's pipeline via an outlet connector. This allows the pretreatment device to filter large particulate impurities from the water source. The water is then pressurized by a booster pump before entering the ultrafiltration device. The ultrafiltration device uses membrane separation technology to remove harmful substances from the water source while retaining some beneficial minerals. The filtered water is then disinfected by the disinfection device and finally supplied to the user through the pipeline. The drinking water treatment system provided by this application features a simple process, low operating costs, easy equipment disassembly, and a small footprint. It also avoids the generation of polluting byproducts during the drinking water treatment process.
[0053] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0054] In one possible implementation, such as Figure 1 As shown, Figure 1 This is a drinking water treatment system 10. External water enters a preliminary sedimentation tank 11 for initial sedimentation. The clear water from the sedimentation tank then enters a primary sedimentation outlet pipe 14. During this process, the water passes through a primary sedimentation filter screen 16 to filter out sediment. A primary sedimentation drain valve 17 periodically discharges the deposited waste. The filtered water then enters a filter membrane cartridge 12 through the primary sedimentation outlet pipe 14 for further filtration. The filtered water then enters a multi-functional filter box 13 through a filter membrane outlet pipe 15. After filtration through pebbles and fine sand, the water is further filtered by activated carbon to form pure water. The staggered distribution of the filter outlets maximizes water flow, thus increasing the purification effect. The pure water filtered by the multi-functional filter box 13 enters a sterilization chamber 18 through a multi-functional outlet pipe 20 and is sterilized by a sterilization lamp. The sterilized water is then stored in a storage tank 19.
[0055] This method of treating drinking water first involves removing sand and impurities from the external water source through a preliminary sedimentation tank 11. The water after sedimentation in the preliminary sedimentation tank 11 then enters a filter membrane cartridge 12 for primary filtration. Next, the filtered water enters a multi-functional filter box 13 for secondary filtration. Following this, the water undergoes secondary filtration and then ultraviolet (UV) sterilization in a sterilization chamber 18. Finally, the UV-sterilized water is stored in a water storage tank 19 for later use. This achieves the effect of treating filtered water that is directly drinkable.
[0056] However, in actual operation, the filter cartridge 12 usually needs to be replaced regularly due to water quality conditions, which leads to excessively high operating costs. In addition, the treatment equipment occupies a large area, making it inconvenient for individual users to use at home and lacking good versatility.
[0057] Based on the above embodiments, this application further provides a drinking water treatment system 100. A pretreatment device 200 filters large particulate impurities from the water source. The water is then pressurized by a booster pump 220 before entering an ultrafiltration device 300. The ultrafiltration device 300 uses membrane separation technology to remove harmful substances from the water source while retaining some beneficial minerals. The filtered water is then disinfected by a disinfection device 400 before being supplied to users through pipelines. The specific structure of the drinking water treatment system 100 provided in this application embodiment will be described below with reference to the accompanying drawings.
[0058] refer to Figure 2 This application provides a drinking water treatment system 100, which may include a pretreatment device 200, an ultrafiltration device 300, and a disinfection device 400. In this embodiment, the outlet of the pretreatment device 200 is connected to the inlet of the ultrafiltration device 300 via an inlet connector 240. The outlet of the ultrafiltration device 300 is connected to the inlet of the disinfection device 400 via a disinfection pipeline 420, and the outlet of the disinfection device 400 is connected to a user pipeline (not shown in the figure) via an outlet connector 430. In this way, the drinking water treatment system 100 can form a relatively complete pipeline. The pretreatment device 200 can perform preliminary filtration of large particulate impurities in the water source, and then enter the ultrafiltration device 300. The ultrafiltration device 300 can use membrane separation technology to filter out harmful substances in the water source, while retaining some mineral elements that are beneficial to the human body. The filtered water source is sterilized and disinfected by the disinfection device 400, so that the water source can be supplied to users through user pipelines after treatment.
[0059] Continue to refer to Figure 2In a specific implementation of this embodiment, the pretreatment device 200 may further include a filter 210 and a booster pump 220. In one possible implementation, the filter 210 and the booster pump 220 may be connected by an inlet pipe 230. In this embodiment, the outlet of the filter 210 can be connected to the inlet of the booster pump 220 via the inlet pipe 230, and the outlet of the booster pump 220 can be connected to the ultrafiltration device 300 via an inlet connector 240. It is understood that the filter 210 can be used to filter large particulate impurities in the water source, while the booster pump 220 can be used to increase the user's water pressure. In this way, after the water source passes through the filter 210, the impurities in it will be filtered out by the filter 210, and then enter the booster pump 220 through the water inlet pipe 230. The booster pump 220 pressurizes the water source to meet the water pressure required by the user, thereby satisfying the user's water demand.
[0060] Continue to refer to Figure 2 Based on the above embodiments, the pretreatment device 200 may further include an inlet valve 250. The inlet valve 250 may be located between the filter 210 and the inlet pipe 230. In one possible implementation, the inlet valve 250 may be installed on the inlet pipe 230, and the inlet valve 250 may be positioned closer to the filter 210. It is understood that the inlet valve 250 can be used to connect or disconnect the circuit between the filter 210 and the inlet pipe 230. In this embodiment, when the inlet valve 250 is open, the inlet pipe 230 may be connected to the filter 210, allowing the filtered water to enter the inlet pipe 230 and then the booster pump 220. In one possible implementation, the inlet valve 250 may be an inlet ball valve, the filter 210 may be a Y-type filter, and the booster pump 220 may be a variable frequency booster pump. This embodiment does not impose any limitations on these aspects.
[0061] Based on the above embodiments, in one possible implementation, the filter 210 may include a filter cartridge and a filter screen (not shown in the figure). It is understood that untreated water can first be filtered through the filter 210, where impurities are intercepted. Large particles are blocked outside the filter cartridge, while small particles are filtered out by the filter screen. The treated water then enters the booster pump 220 via the inlet valve 250 and inlet pipe 230. After being pressurized by the booster pump 220, the pressurized water enters the ultrafiltration device 310 through the easily installed inlet connector 240.
[0062] It is understandable that the filter 210 filters out rust, sand, solid particles, etc. from the untreated water source to protect the fittings on the subsequent equipment pipes from wear and blockage, and the booster pump 220 is used to increase the water pressure at the inlet to maintain the normal operation of the equipment.
[0063] Continue to refer to Figure 2 Based on the above embodiments, the ultrafiltration device 300 may further include an ultrafiltration apparatus 310. In one possible implementation, the end of the ultrafiltration apparatus 310 facing the pretreatment device 200 may have an inlet 311, which may be connected to an inlet connector 240. Thus, pressurized water can enter the inlet 311 of the ultrafiltration apparatus 310 through the inlet connector 240. Correspondingly, the end of the ultrafiltration apparatus 310 facing the disinfection device 400 may have an outlet 312, which may be connected to the disinfection device 400. Thus, water entering the ultrafiltration apparatus 310, after ultrafiltration treatment, can flow out through the outlet 312 and then into the disinfection device 400.
[0064] Based on the above embodiments, in one possible implementation, the ultrafiltration device 310 may include a housing, which may be made of stainless steel. The ultrafiltration device 310 may contain an ultrafiltration membrane. It is understood that the ultrafiltration membrane can be used to filter out harmful substances from the water source. In this embodiment, the ultrafiltration membrane may be a hollow fiber ultrafiltration membrane, and this embodiment is not limited thereto. Thus, utilizing the membrane separation technology of the hollow fiber ultrafiltration membrane, harmful substances such as rust, silt, suspended solids, colloids, bacteria, and macromolecular organic matter in the water source can be filtered out, while retaining some beneficial mineral elements. After the water entering the ultrafiltration device 310 undergoes membrane separation treatment, harmful substances are filtered out while retaining beneficial mineral elements. The ultrafiltration water then flows out through the outlet 312 of the ultrafiltration device 310 and then flows through the disinfection pipeline 420 to the disinfection device 400.
[0065] Continue to refer to Figure 2Based on the above embodiments, one end of the ultrafiltration device 300 may also be provided with a drain outlet 313. The drain outlet 313 can be connected to a drain pipe 320, through which the concentrated water filtered by the ultrafiltration device 300 can be discharged. It should be noted that the concentrated water can be wastewater, sewage, and waste liquid generated during industrial production, containing industrial raw materials, intermediate products, and finished products lost with the water, as well as pollutants generated during the production process. It is understood that after impurities in the water source are filtered out by the filter 210 and the ultrafiltration device 310, the water is discharged from the drain outlet 313 of the ultrafiltration device 310 along with some water from the drain pipe 320, while the filtered water can flow into the disinfection device 400 through the disinfection pipe 420.
[0066] Continue to refer to Figure 2 Based on the above embodiments, the ultrafiltration device 300 may further include a drain valve 330. The drain valve 330 may be installed on the drain pipe 320. It is understood that the drain valve 330 can be used to connect or disconnect the drain pipe 320. Thus, when water from the pretreatment device 200 enters the ultrafiltration device 300 for filtration, the drain valve 330 opens after concentrated water is produced, allowing impurities in the water to be filtered out by the ultrafiltration device 310 and discharged smoothly from the drain pipe 320 along with some water through the drain outlet 313 of the ultrafiltration device 310.
[0067] In one possible implementation, the drain valve 330 can be a drain ball valve, which is not limited in this embodiment. It is understood that the drain port 313 at one end of the ultrafiltration device 310 is connected to the drain pipe 320, so that the concentrated water stored inside the ultrafiltration device 310 is periodically discharged through the drain ball valve.
[0068] Continue to refer to Figure 2 Based on the above embodiments, the disinfection device 400 may further include a sterilizer 410. In one possible implementation, a disinfection pipeline 420 may be provided between the ultrafiltration device 310 and the sterilizer 410, meaning the ultrafiltration device 310 and the sterilizer 410 can be connected via the disinfection pipeline 420. In this embodiment, the inlet of the sterilizer 410 can be connected to the outlet 312 of the ultrafiltration device 300 via the disinfection pipeline 420, while the outlet of the sterilizer 410 can be connected to the outlet connector 430. It is understood that the sterilizer 410 can be used to disinfect water sources. Thus, water treated by ultrafiltration enters the sterilizer 410 through the disinfection pipeline 420, where it undergoes disinfection treatment. The treated water then flows to the user's pipeline through the outlet connector 430 for user use.
[0069] Continue to refer toFigure 2 Based on the above embodiments, the disinfection device 400 may further include a water outlet valve 440. The water outlet valve 440 may be located between the water outlet connector 430 and the user pipeline. In one possible implementation, the water outlet valve 440 may be positioned close to the side of the water outlet connector 430. It is understood that the water outlet valve 440 can be used to connect or disconnect the loop between the water outlet connector 430 and the user pipeline. In this embodiment, when the water outlet valve 440 is open, the water outlet connector 430 can be connected to the user pipeline, and the water source disinfected by the disinfector 410 can enter the user pipeline through the water outlet connector 430 and the water outlet valve 440 for user use. In one possible implementation, the water outlet valve 440 may be a ball valve; this embodiment does not impose such a limitation.
[0070] In one possible implementation, the sterilizer 410 can be an ultraviolet (UV) sterilizer 410. It should be noted that the working principle of UV disinfection is to utilize UVC ultraviolet light, which has bactericidal properties, to destroy the molecular structure of microbial cells, causing the death of growing and / or regenerating cells, thereby achieving sterilization and disinfection to ensure the safety of drinking water. Understandably, the water source, after ultrafiltration treatment, flows through the disinfection pipe 420 into the sterilizer 410. The UV light itself destroys the molecular structure of microbial cells, causing cell death, thus making the water source sterilization more thorough. Finally, it is connected to the user's pipeline and household faucet through the outlet connector 430 and outlet valve 440 for user use.
[0071] In another possible implementation, the sterilizer 410 can also use sodium hypochlorite for disinfection. Sodium hypochlorite disinfection is easy to store, easy to decompose, leaves no residue, and is non-toxic and harmless to the human body, which can effectively reduce equipment costs.
[0072] Continue to refer to Figure 2 Based on the above embodiments, the drinking water treatment system 100 may further include a housing 500. In one possible implementation, the housing 500 may be rectangular in shape; however, this application embodiment does not limit the shape of the housing 500. In this application embodiment, the booster pump 220, the ultrafiltration device 310, and the sterilizer 410 can all be located within the housing 500, providing good protection.
[0073] Continue to refer to Figure 2Based on the above embodiment, a first through hole, a second through hole, and a third through hole can be respectively opened on the side of the housing 500 facing the filter 210. The first through hole corresponds to the water inlet pipe 230, the second through hole corresponds to the drain pipe 320, and the third through hole corresponds to the water outlet connector 430. It is understood that one end of the water inlet pipe 230 passes through the first through hole and is connected to the water inlet valve 250. One end of the drain pipe 320 passes through the second through hole and is connected to the drain valve 330, and one end of the water outlet connector 430 passes through the third through hole and is connected to the water outlet valve 440. In this way, the water inlet valve 250, the drain valve 330, and the water outlet valve 440 can all be located outside the housing 500, facilitating user operation.
[0074] Continue to refer to Figure 2 Based on the above embodiments, the end of the housing 500 facing away from the filter 210 may have a lifting lug 600. In one possible implementation, the number of lifting lugs 600 can be at least two; however, this embodiment does not limit the number of lifting lugs 600. In this embodiment, two lifting lugs 600 are used as an example. It is understood that the entire housing 500 can be fixedly suspended to the wall by fasteners passing through the two lifting lugs 600. In one possible implementation, the fastener can be a bolt; this embodiment does not limit this. Thus, the entire drinking water treatment system 100 occupies a smaller area and is easier to install and disassemble, making it more flexible and convenient.
[0075] In this embodiment, the water source first enters the pretreatment device 200 for treatment. The untreated water is initially filtered by the filter 210. The pre-filtered water then flows through the inlet valve 250 and inlet pipe 230 into the booster pump 220. The booster pump 220 pressurizes the water, which then flows through the inlet connector 240 into the ultrafiltration device 310. Next, the water entering the ultrafiltration device 310 undergoes membrane separation treatment, which removes harmful substances while retaining beneficial minerals. The ultrafiltered water then flows out through the outlet 312 of the ultrafiltration device 310 and then through the disinfection pipe 420 into the disinfection device 400. Furthermore, impurities in the water source are filtered out by filter 210 and ultrafiltration device 310, and then discharged from the drain outlet 313 of ultrafiltration device 310 along with some water through drain pipe 320. The filtered water source can flow into disinfection device 400 through disinfection pipe 420. Finally, the ultrafiltration treated water source enters sterilizer 410 through disinfection pipe 420, where it is sterilized and disinfected. The treated water source then flows to the user's pipeline through outlet connector 430 for user use.
[0076] In this embodiment, the drinking water treatment system 100 provided by this application features a simple process, low operating cost, convenient equipment disassembly, and small footprint. It also avoids the generation of polluting byproducts during drinking water treatment. It is understood that after ultrafiltration treatment, the water source has a high greywater recovery rate and low operating cost. Furthermore, the use of a sterilizer 410 to disinfect the water source results in low energy consumption, no secondary pollution, and avoids the generation of polluting byproducts, ensuring the safety of drinking water.
