DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with Figures 1-6.

The embodiment of the present application discloses a water treatment system.

1-3, a water treatment system includes a water supply mechanism 1, a sand filter 21, a softener 31, a salt box 32 and a water supply mechanism 4, wherein the input end of the sand filter 21 is assembled with the input end of the water supply mechanism 1, the input end of the softener 31 is assembled with the output end of the sand filter 21, the output end of the softener 31 is equipped with the salt box 32, and the water supply mechanism 4 includes a water supply pump, which is assembled with the salt box 32 and the user equipment at the same time, and the water supply pump transports the water treated by the salt box 32 to the user equipment.

In this application, the water treatment system is suitable for scenarios such as direct drinking water supply to residential communities, water purification in aquaculture systems, water use in HVAC systems, and water use in factories. Since the water sources input into these application scenarios are different and the requirements for water quality are different in different scenarios, the operator can adapt and adjust the water treatment system devices according to the actual application scenarios.

Referring to Figure 1, in the scenario of direct drinking water supply to households in residential communities, the water supply organization 4 uses municipal tap water as raw water, and after deep filtration by the water treatment system, delivers directly drinkable pure water to each household through the water supply pipe to ensure the user's water safety. At the same time, the community return water returns to the water treatment system through the return water pipe to achieve a water treatment cycle.

Specifically, the water supply mechanism 1 includes a raw water tank 11 and a raw water pump 12. The input end of the raw water pump 12 is assembled with the raw water tank 11, and the output end thereof is assembled with the sand filter 21. The raw water tank 11 is connected to an external water source. The raw water is statically treated in the raw water tank 11 to achieve a certain purification effect. The raw water pump 12 serves as a power source to pump the raw water in the raw water tank 11 into the sand filter 21. The sand filter 21 is used to filter particulate matter with a diameter between 20 microns and 100 microns in the sewage. In this process, the sand filter 21, as a pretreatment mechanism, can remove suspended matter in the sewage and physically intercept larger particulate matter to achieve the purpose of preliminary impurity removal.

In the scenario of direct drinking water supply to households in residential areas, a carbon filter 22 is added between the sand filter 21 and the softener 31. The input end of the carbon filter 22 is assembled with the sand filter 21, and the output end is assembled with the softener 31. The output end of the softener 31 is directly connected to the salt box 32 to ensure that the water softened by the softener 31 enters the salt box 32 for cleaning. Under the action of the softener 31, the calcium and magnesium ions in the water can be reduced, thereby obtaining softened water. The salt box 32 then replaces the calcium and magnesium ions in the resin and discharges the waste water.

In order to further improve the quality of drinking water, a reverse osmosis filter device 5 and a water pump 51 are arranged outside the salt box 32. The water pump 51 is used as a power source to transport the water treated by the salt box 32 to the input end of the reverse osmosis filter device 5. In addition, the water treatment system also includes a concentrated water treatment mechanism 6 arranged outside the reverse osmosis filter device 5. The concentrated water treatment mechanism 6 is connected to the input end of at least one reverse osmosis filter device 5. Here, the number of reverse osmosis filter devices 5 is not limited, and the number is at least one, so that the number of reverse osmosis filter devices 5 is proportional to the number of floors of the building in the living community.

When in use, the raw water passes through the raw water tank 11, the sand filter 21, the carbon filter 22, the softener 31, the salt box 32 and the reverse osmosis filter device 5 in sequence. The raw water pump 12 serves as a power source to pump the raw water in the raw water tank 11 into the sand filter 21. The water delivery pump 51 serves as a power source to pump the soft water in the salt box 32 into the reverse osmosis filter device 5, which helps to speed up the particle matter filtration efficiency of the water treatment system. The water after the calcium and magnesium ions are replaced in the salt box 32 is transported to the reverse osmosis filter device 5. Under the action of the reverse osmosis filter device 5, the dissolved solids in the water can be effectively removed, and various microorganisms, organic matter, inorganic matter and other substances can be removed, thereby producing high-purity water.

A security filter 34 is arranged outside the salt box 32. The security filter 34 is assembled with the salt box 32 and the reverse osmosis filter device 5 at the same time. The security filter 34 has the function of maintaining the stability of the system. During the water treatment process, it can effectively protect the reverse osmosis membrane of the reverse osmosis filter device 5 and reduce the contamination or blockage of the reverse osmosis membrane.

At the same time, any one of the sand filter 21, the carbon filter 22, the softener 31, and the reverse osmosis filter device 5 is assembled with the concentrated water treatment mechanism 6, or any combination of the sand filter 21, the carbon filter 22, the softener 31, and the reverse osmosis filter device 5 is assembled with the concentrated water treatment mechanism 6, so that the concentrated water generated by each mechanism after water treatment is collected and recycled by the concentrated water treatment mechanism 6, which helps to reduce environmental pollution. In addition, the concentrated water can be converted into other useful substances that can be recycled, thereby improving the utilization rate of water resources and maximizing benefits.

Referring to Figure 1, the concentrate water treatment mechanism 6 includes a concentrate water tank 61, a concentrate water filter 62, a concentrate water pump 63 and a concentrate water recovery component 64. The concentrate water tank 61, the concentrate water filter 62, the concentrate water pump 63 and the concentrate water recovery component 64 are connected in sequence, and the sand filter 21, the carbon filter 22, the softener 31, and the reverse osmosis filter device 5 are assembled in any combination or any one of them to the input end of the concentrate water tank 61.

During the concentrated water treatment process, the concentrated water tank 61 can provide storage space for concentrated water collection, so that the concentrated water can be left to stand for treatment, which can achieve a certain purification effect. The concentrated water filter 62 is a precision filter. The concentrated water passes through the concentrated water filter 62 to filter suspended solids, particles and other impurities, and then the concentrated water pump 63 is used as a power source to transfer the filtered concentrated water to the concentrated water recovery unit 64 for evaporation treatment. During the process, heating or natural evaporation is used to evaporate the water in the water body, leaving concentrated solid matter or a more concentrated solution, and then the concentrated water is converted into other useful substances that can be recycled. The desalinated and filtered water can also be used in other application scenarios to improve the utilization rate of water resources and maximize benefits.

1, the water treatment system further includes a sterile treatment mechanism 7 disposed outside the reverse osmosis filter device 5, the sterile treatment mechanism 7 is connected to the output end of at least one reverse osmosis filter device 5, and is used to sterilize the water after desalination filtration treatment. The sterile treatment mechanism 7 can provide a temporary storage function, and at the same time can reduce or eliminate residual microorganisms in the water, ensure the sterility of the final water production, and ensure hygienic safety.

Specifically, the aseptic treatment mechanism 7 includes an ozone generator 71, a sterile water production tank 72 and an ultraviolet sterilization component 73. The sterile water production tank 72 is connected to the output end of at least one reverse osmosis filtration device 5. The ozone generator 71 is assembled with the sterile water production tank 72, and the ultraviolet sterilization component 73 is assembled with the sterile water production tank 72 and the water supply mechanism 4 at the same time.

When in use, the filtered water is first stored in the sterile water production tank 72, which can buffer the pressure to a certain extent, balance the pressure of the entire water treatment system, and ensure the stability of the water supply. The ozone generator 71 has the function of quickly eliminating microorganisms and oxidizing and decomposing organic matter in the water. The ozone generator 71 further disinfects and sterilizes this part of water, removes odors, and changes the taste of the water, so that the water in the sterile water production tank 72 is sterile pure water. Under the action of the ultraviolet sterilization component 73, it can ensure that the water section from the sterile water production tank 72 to the water supply mechanism 4 is also a sterile environment, reducing the secondary pollution of pure water and ensuring the quality of water supply. The water supply mechanism 4 then delivers sterile and odorless pure water to each user, effectively improving the user's water safety.

Furthermore, in the process of water return in the community, the domestic water referred to here is pure water containing only some organic matter, microorganisms and other pollutants. A precision filter 74 and an ultraviolet sterilization component 73 are arranged in sequence at the output end of the return water pipe, and the return water pipe and the precision filter 74 and the ultraviolet sterilization component 73 close to it are connected in sequence, so that the domestic water is preliminarily filtered and sterilized before entering the sterile water production tank 72, and then mixed with the pure water originally stored in the sterile water production tank 72. Under the action of the ozone generator 71, further disinfection and sterilization are carried out, odor is removed, and the taste of the water is changed. Finally, it enters another ultraviolet sterilization component 73 for disinfection and is transported to users by the water supply mechanism 4.

Compared with the prior art, the present application achieves preliminary filtration and reduces water hardness, with multiple institutions working together to ensure that after the superior institution removes impurities, the remaining impurities will not have a negative impact on the subordinate institutions, reducing blockage, damage or scaling of each institution. At the same time, it ensures that sewage can be purified, effectively removes organic matter and residual chlorine in sewage, improves the taste and odor of water, and can further purify water quality before softening, ensuring the quality of the final effluent.

Referring to Figure 2, in the aquaculture system water purification scenario or the factory water use scenario, the water treatment systems of the two are basically the same as the residential community direct drinking water supply scenario. The main difference is that the residential community direct drinking water supply scenario has a waterway for the community return water, while the return water of the aquaculture system water purification scenario and the factory water use scenario is highly polluted and is not recycled, so that the water supply process and water supply process of the entire water treatment system maintain a high-cleanliness environment to reduce the occurrence of cross contamination.

In addition, to facilitate resource acquisition and management, the water purification scenes of the aquaculture system are generally set up in sites far away from the city. Therefore, groundwater, surface water, mountain reservoir water, and purified water are basically used as water sources to reduce water transfer costs; the direct drinking water supply scenes in residential communities and factory water use scenes are generally close to the areas where people live, so municipal tap water is used as the water source to improve the convenience of water use.

3 , in the scenario of the warm air system, only the sand filter 21 is used as a filter connected between the water supply mechanism 1 and the softener 31. In this scenario, the carbon filter 22 is omitted, and the sand filter 21 is directly assembled with the softener 31. By only using the sand filter 21 to remove larger suspended particles, sediments and some microorganisms, the soft water treatment equipment used in combination with the subsequent softener 31 and the salt box 32 is protected to prevent the soft water treatment equipment from being damaged by large particles, thereby providing a relatively clean water source for the soft water treatment equipment. In this scenario, the organic matter content in the water is not high. By omitting the carbon filter 22, it is possible to save costs while ensuring the cleanliness of the water, and will not affect the subsequent soft water treatment effect.

Moreover, in this scenario, the reverse osmosis filtration device 5 is omitted, and a softened water tank 33 is further provided outside the salt box 32, so that the softened water tank 33 is used as a buffer zone and is assembled with the salt box 32 and the water supply mechanism 4 at the same time. The softened water tank 33 is arranged at the next level of the salt box 32, and can provide the functions of storing softened water, continuously supplying water, reducing brine pollution, maintaining water quality stability, and reducing brine backflow, effectively reducing the mixing of brine and softened water, ensuring the water quality safety of the water supply mechanism 4, thereby protecting the user's water safety.

In the embodiments of the present application, according to different application scenarios, the water treatment system can choose to add or discard the carbon filter 22, can choose to add or discard the softening water tank 33, can choose to add or discard the reverse osmosis filtration device 5, can choose to add or discard the return water channel, thereby effectively increasing the adaptability of the water treatment system and meeting specific application needs in the scenarios of living quarters, breeding systems, and factory water use.

1 and 4 , the reverse osmosis filtration device 5 used in the residential community direct drinking water supply scenario, the aquaculture system water purification scenario, and the factory water use scenario has the same structure. When used, the input end of the concentrated water treatment mechanism 6 is assembled with the input end of the reverse osmosis filtration device 5 .

Specifically, the reverse osmosis filtration device 5 includes a raw water guide membrane 52, an RO membrane 53, a water permeable membrane 54, a water collecting pipe 55 and an anti-seepage ring 56, wherein the RO membrane 53 has two layers, and the RO membrane 53, the water permeable membrane 54, the RO membrane 53, and the raw water guide membrane 52 are stacked from the outside to the inside, and the RO membrane 53, the water permeable membrane 54, the RO membrane 53, and the raw water guide membrane 52 are all rectangular membrane structures of the same size. When used, the water collecting pipe 55 is first placed on the upper surface of the raw water guide membrane 52, so that the four layers of membrane are simultaneously wrapped around the water collecting pipe 55, and finally are wound into a cylindrical structure.

At the same time, after the cross-sections of the RO membrane 53, the permeable membrane 54, the RO membrane 53, and the raw water guide membrane 52 are stacked, the section distributed on the input end side is defined as the input end section, and the section distributed on the output end side is defined as the output end section, to ensure that the tightness between different membrane layers and between the raw water guide membrane 52 and the water collecting pipe 55 is within the specified range, to ensure that the reverse osmosis filtration device 5 will not become loose during water treatment.

More specifically, a plurality of water holes 551 are formed through the outer wall of the water collecting pipe 55 placed in the cylindrical structure, and an anti-seepage ring 56 is fixed on the outer wall of the output end of the water collecting pipe 55 extending outside the cylindrical structure, ensuring that soft water penetrates from the input end section, and pure water flows from the outer diameter to the inner diameter of the cylindrical structure until it reaches the water holes 551 of the water collecting pipe 55. The pure water finally enters the interior of the water collecting pipe 55 from the water holes 551 and is then discharged, and then the waste water is discharged from the output end section.

4 and 5 , in a preferred embodiment, a filter screen 57 is detachably installed at the input end of the reverse osmosis filter device 5, so that the filter screen 57 is in contact with the cross-section of the input end. When soft water enters the reverse osmosis filter device 5, it first contacts the filter screen 57. The filter screen 57 can initially filter the suspended particles with a larger volume floating in the soft water, effectively reducing the suspended particles from entering the reverse osmosis filter device 5 and causing blockage, and can play a pre-treatment and anti-blockage effect, thereby reducing the number of times the operator disassembles the reverse osmosis filter device 5 for cleaning.

Furthermore, a waterstop 596 is provided on the outside of the input end of the cylindrical structure composed of the RO membrane 53, the permeable membrane 54, the RO membrane 53, and the raw water guide membrane 52, that is, the waterstop 596 is arranged on the outside of the outermost RO membrane 53. Here, the waterstop 596 is a trumpet-shaped structure, so that the small port of the waterstop 596 is mounted on the outer wall of the cylindrical structure, and the direction of the large port is opposite to the soft water input direction, ensuring that the soft water can only pass through the filter 57 first, and then enter the interior of the reverse osmosis filter 57 through the input end cross section. In this process, the waterstop 596 can provide a guide for the soft water, effectively reduce the situation where the soft water overflows without being purified, and help to improve the purification effect of the soft water.

Furthermore, a mounting seat 58 is installed at the input end of the reverse osmosis filter device 5, and the mounting seat 58 is also a cylindrical seat structure, wherein a reflux chamber 581 is provided inside the mounting seat 58 and at one end close to the reverse osmosis filter device 5, and the height dimension of the reflux chamber 581 is consistent with the diameter dimension of the filter screen 57, and a guide channel 582 is provided inside the mounting seat 58 and at one end away from the reverse osmosis filter device 5, and the height dimension of the guide channel 582 is consistent with the inner diameter dimension of the water collecting pipe 55, and at the same time, the guide channel 582 is connected to the reflux chamber 581.

5 and 6, a cleaning mechanism 59 is fixed in the mounting seat 58, and the cleaning mechanism 59 includes a flusher 591, a first water channel 592, a second water channel 593 and an arc-shaped water baffle 594, wherein the flusher 591 is fixed to the inner wall of the mounting seat 58, and the cross-sections of the first water channel 592 and the second water channel 593 are both "U"-shaped, the input end of the first water channel 592 is assembled with the flusher 591, and the input end of the second water channel 593 is fixed with the output end of the first water channel 592, so that an angle of 90°-150° is left between the first water channel 592 and the second water channel 593, and the arc-shaped water baffle 594 is fixed to the inner wall of the mounting seat 58 close to the reflux chamber 581, and the center of the arc-shaped water baffle 594 points to the side close to the second water channel 593.

The number of cleaning mechanisms 59 in the mounting seat 58 is not limited, but in the embodiment of the present application, two cleaning mechanisms 59 are shown, and the two cleaning mechanisms 59 are symmetrically distributed along the central axis of the mounting seat 58. When soft water is introduced, the soft water passes through the guide channel 582, the reflux chamber 581, the filter screen 57, and the reverse osmosis filter device 5 of the mounting seat 58 in sequence. In this process, under the guidance of the guide channel 582 and the influence of the two groups of cleaning mechanisms 59, most of the soft water is concentrated around the central axis of the mounting seat 58 to flow, and then after being blocked by the filter screen 57 and the input end section, the soft water diffuses around the filter screen 57. Under the action of water pressure, the soft water will be pressed into the reverse osmosis filter device 5, and the larger suspended matter will be hung on the surface of the filter screen 57.

Then start the flusher 591, which provides a high-pressure water source. The high-pressure water source flows along the first water channel 592 and the second water channel 593, and then quickly impacts the arc-shaped water baffle 594 close to them. This part of water flows along the inner wall of the arc-shaped water baffle 594. Under the action of the arc-shaped water baffle 594, the high-pressure water source can flush the surface of the filter screen 57 from top to bottom or from bottom to top at a certain angle, so that the suspended matter attached to the surface of the filter screen 57 can be cleaned.

Furthermore, a certain space is left between the output end of the arc-shaped water baffle 594 and the filter screen 57, and a drain port 595 is opened at the bottom of the mounting seat 58. The output end of the drain port 595 is connected to the concentrated water treatment mechanism 6 through the concentrated water recovery pipe. When the two cleaning mechanisms 59 clean the filter screen 57 at the same time, the water source of the cleaning mechanism 59 placed on the top of the mounting seat 58 flushes obliquely downward, and the water source of the cleaning mechanism 59 placed at the bottom of the mounting seat 58 flushes obliquely upward, so that the two high-pressure water sources converge and concentrate on cleaning the middle part of the filter screen 57, effectively improving the cleaning effect. The aqueous solution with various impurities such as suspended matter is concentrated water, and the concentrated water is discharged from the drain port 595 to the concentrated water treatment mechanism 6.

The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
