[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5As shown in Embodiment 1, a benchtop-type pure water treatment system includes a pure water treatment unit and a benchtop 1. The upper part of the benchtop 1 is equipped with a water inlet pipe 5, the outlet of which is connected to a tap faucet 4 installed on the benchtop 1 and the pure water treatment unit. The outlet of the pure water treatment unit is connected to a pure water faucet 3 installed on the benchtop 1. The lower part of the benchtop 1 is equipped with a cabinet 2, and the pure water treatment unit is housed within the cabinet 2. The pure water treatment unit contains multiple filter cartridges that sequentially treat water. These filter cartridges are built into the benchtop, resulting in a high degree of integration and effectively saving laboratory space. The experimental bench 1 is equipped with a tap water faucet and a pure water faucet 3. It replaces the tap water experimental bench 1 in the existing laboratory and also replaces the pure water machine in the laboratory. The integrated design takes up less space. The separate setting of the tap water faucet 4 and the pure water faucet 3 makes it convenient for the laboratory to use pure water and tap water respectively, making it more convenient to use. It can meet the requirements of water for conventional production processes and water for cleaning laboratory instruments. It can be used as the water source for ultrapure water systems, high-pressure steam sterilizers, environmental test chambers, electrochemical and organic matter analysis, bottle washing machines, salt spray chambers, ultrasonic cleaning, plant tissue culture and other instruments.

[0024] In this embodiment, the pure water treatment unit includes a pretreatment component 6. The inlet end of the pretreatment component 6 is connected to the inlet pipe 5, and the outlet end of the pretreatment component 6 is sequentially connected to a PP filter component 7, an RO membrane component 8, a UV ultraviolet component 9, and a deionization component 10. The deionization component 10 is connected to the pure water faucet 3. The cabinet 2 includes a back panel 11, with a base connected to the lower part of the back panel 11. Side panels are connected to both sides of the back panel 11, and an openable cabinet door is installed in front of the two side panels. Several fixing clamps are provided on the back panel 11, and the fixing clamps are respectively connected to the corresponding PP filter component 7, RO membrane component 8, and UV ultraviolet component 9. The body material is corrosion-resistant and conforms to GLP specifications. A modular structure formed by multiple components is adopted, in which all interfaces adopt the existing quick-connect design, making maintenance quick, simple, and convenient. NSF-certified connection pipes and connectors are used to connect the components, minimizing the precipitation of Toc and stabilizing water quality. The system uses tap water as its source and can conveniently and quickly produce RO reverse osmosis water and DI deionized pure water, employing a two-stage reverse osmosis process. The system has a production capacity of 100L / h, a resistivity exceeding 1MΩ / cm, a high degree of integration, a small footprint, and the produced water quality meets the Class II water quality standards established by GB / T6682-2008, ASTM, and CLSI. Furthermore, the system can be optionally upgraded to a central pure water system by adding an existing circulation conveying system.

[0025] like Figures 1-5As shown in Example 2, a benchtop-type pure water treatment system differs from Example 1 in that the pretreatment component 6 includes a water storage tank placed inside the cabinet 2. The water storage tank contains a multi-media filter cartridge. The inlet of the water storage tank is connected to the inlet pipe 5, and the outlet of the water storage tank is connected to the PP filter component 7. The pretreatment filter cartridge, which can be purchased commercially, is located inside the pretreatment water storage tank. The purpose of the pretreatment component 6 is to remove large particulate impurities from tap water, adsorb harmful substances, and soften the water quality, thereby protecting downstream equipment, reducing maintenance costs, and ensuring the stable operation of the system.

[0026] In this embodiment, the PP filter assembly includes a PP filter tank, which is detachably connected to a fixing plate 12. The fixing plate 12 is mounted on the back plate 11 of the cabinet 2, and the PP filter tank is located above the RO membrane assembly 8. The PP filter tank contains a PP cotton filter element, and the inlet of the PP filter tank is connected to the outlet of the water storage tank. The filtration accuracy of the PP filter element is between 1 micrometer and 100 micrometers, which can further remove impurities from tap water, achieving deep filtration.

[0027] In this embodiment, the RO membrane assembly 8 includes an RO filter tank 1 8-1 and an RO filter tank 2 8-3. Both the RO filter tank 1 8-1 and the RO filter tank 2 8-3 are equipped with RO reverse osmosis membrane filter elements. Through reverse osmosis technology, dissolved salts, colloids, microorganisms, organic matter and other impurities in the water are effectively removed. Both RO filter tank 1 (8-1) and RO filter tank 2 (8-3) have wastewater discharge outlets at their lower parts. Both RO filter tanks 1 (8-1) and RO filter tank 2 (8-3) are detachably connected to fixing plates 2 (13), which are installed on the back plate 11 of cabinet 2. Both RO filter tanks 1 (8-1) and RO filter tank 2 (8-3) contain RO filter cartridges. A booster pump 1 (8-2) is connected to the inlet of RO filter tank 1 (8-1), and RO filter tank 1 (8-1) is connected to the outlet of the PP filter tank via booster pump 1 (8-2). A booster pump 2 (8-4) is connected to the inlet of RO filter tank 2 (8-3), and RO filter tank 2 (8-3) is connected to the outlet of RO filter tank 1 (8-1) via booster pump 2 (8-4). This dual-stage reverse osmosis system effectively removes 99% of soluble inorganic ions, organic matter, microorganisms, and particulate matter.

[0028] In this embodiment, both booster pump 8-2 and booster pump 8-4 are detachably equipped with corresponding fixing plates 14, which are installed on the back panel 11 of the cabinet 2. Each fixing plate 14 includes a connecting plate 16, on which two parallel transition plates 17 are connected. Each transition plate 17 has a U-shaped groove. The two transition plates 17 provide better fixation of the booster pumps, ensuring stable installation within the cabinet 2 with good stability.

[0029] All other structures are the same as in Example 1.

[0030] like Figures 2-5 As shown in Example 3, a benchtop-type pure water treatment system differs from Example 2 in that the UV component 9 includes a UV filter. A four-piece fixing plate 15 is detachably mounted on the UV filter and installed on the back panel 11 of the cabinet 2. The inlet of the UV filter is connected to the outlet of the RO filter tank 8-3. Each of the four-piece fixing plates 12, 13, and 15 includes two U-shaped clamps 18, with connecting rods 19 connected to the U-shaped clamps 18, and horizontal plates 20 connected to the connecting rods 19. The system employs a dual-wavelength (185nm & 254nm) UV lamp assembly, effectively sterilizing while reducing TOC content.

[0031] In this embodiment, the deionization assembly 10 includes a deionizer, which is placed inside the cabinet 2. The inlet of the deionizer is connected to the outlet of the ultraviolet filter, and the outlet of the deionizer is connected to a pure water faucet 3. The deionizer uses a commercially available downflow deionization module, which effectively prevents resin stratification, ensures column efficiency, has a large resin loading capacity, and produces five times the water of ordinary purification columns. It uses imported mainstream membranes and imported nuclear-grade ion exchange resin to ensure the quality of deionized pure water.

[0032] All other structures are the same as in Example 2.
