Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment device. Background Technology

[0002] Many cities use reservoirs as their water supply source, but due to the long storage time, factors such as anaerobic fermentation of the reservoir bottom mud, decay of fallen leaves, and the proliferation of algae and freshwater organisms cause the water quality to change continuously, and the situation is more serious in warm and humid areas.

[0003] To improve water supply quality, reservoir water is often subjected to biological and chemical oxidation. Biological oxidation can re-oxygenate and purify the water, while chemical oxidation can inhibit the growth of algae and freshwater shellfish. Traditional chemical oxidation commonly uses potassium permanganate and sodium hypochlorite, among which sodium hypochlorite has both oxidation and disinfection effects. However, chlorine-based disinfectants easily react with parent organic matter to generate disinfection byproducts such as chloroform and carbon tetrachloride. If a large amount of chlorine-based disinfectant is added during the pretreatment of reservoir raw water, the risk of generating disinfection byproducts will increase. If the amount added is insufficient, it will be difficult to inhibit the growth of algae and shellfish, threatening the safe operation of the transmission pipeline and fine screen, and directly affecting water safety. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a water treatment device that achieves efficient water purification by working together with an ozone generating component and a disinfection component, effectively inhibiting the growth of algae and shellfish and improving water quality safety.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A water treatment device, comprising:

[0007] The reaction tank has an inlet and an outlet. The inlet is used to guide water flow into the reaction tank, and the outlet is used to discharge water flow.

[0008] An ozone generating assembly, comprising an ozone generator for releasing ozone into the reaction tank;

[0009] A water supply assembly, comprising a water supply pipe, one end of which is connected to the water inlet and the other end of which is connected to an external structure;

[0010] A disinfection assembly, comprising a disinfectant storage tank filled with disinfectant; the disinfectant storage tank is connected to the water supply pipe.

[0011] Furthermore, the reaction tank is also equipped with a number of ultraviolet lamps, which are distributed at intervals within the reaction tank.

[0012] Furthermore, the disinfection assembly also includes a metering pump and a guide pipe, one end of which is connected to the disinfectant storage tank and the other end of which is connected to the water delivery pipe; the metering pump is mounted on the guide pipe and is used to drive the sodium hypochlorite solution through the guide pipe into the water delivery pipe.

[0013] Furthermore, the disinfection assembly also includes a flow meter, which is mounted on the guide pipe and located between the metering pump and the water delivery pipe.

[0014] Furthermore, the reaction tank has a water storage chamber, and a partition is provided in the water storage chamber. The partition separates the water storage chamber into a reaction chamber and a water collection chamber. The water inlet is connected to the reaction chamber, and the water outlet is located in the water collection chamber. An overflow hole is provided on the partition, and the overflow hole is used to guide the water flow to the water collection chamber.

[0015] Furthermore, a filter plate is provided at the overflow hole, and the filter plate covers the overflow hole.

[0016] Furthermore, it also includes a water pump, which is mounted on the water supply pipe and connected to the water supply pipe.

[0017] Furthermore, the ozone generating assembly also includes a jet mixer, which is connected to the water supply pipe and the ozone generator via pipes.

[0019] Compared with existing technologies, the beneficial effects of this invention are as follows: In practical use, after the water source flows into the reaction tank, the ozone generator starts working, releasing ozone into the reaction tank, allowing the water source and ozone to fully mix and react. This process can effectively degrade and reduce disinfection byproducts, while also inhibiting and destroying algae and shellfish in the raw water, thereby achieving preliminary purification of the water source. Subsequently, the pre-purified water source flows through the water delivery pipe. At this time, the sodium hypochlorite solution in the disinfectant storage tank is introduced into the water delivery pipe for secondary purification of the water source, enabling the water source to be safely transported to the water purification plant for people to use, greatly improving the safety of water use.

[0023] The present invention will now be further described in conjunction with specific embodiments:

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] like Figure 1 The water treatment device shown includes a reaction tank 10, an ozone generating component, a water conveying component, and a disinfection component. The reaction tank 10 has an inlet and an outlet. The inlet is used to guide water flow into the reaction tank 10, and the outlet is used to discharge the water flow. The ozone generating component includes an ozone generator 20, which is used to release ozone into the reaction tank 10. The water conveying component includes a water pipe 40, one end of which is connected to the inlet, and the other end of which is connected to an external structure. The disinfection component includes a disinfectant storage tank 30, which stores sodium hypochlorite solution. That is, the disinfectant storage tank 30 is filled with sodium hypochlorite solution, and the disinfectant storage tank 30 is connected to the water conveying pipe 40.

[0027] Based on the above structure, during assembly, the inlet is connected to an external waterway (such as a water storage tank), the outlet is connected to the water supply pipe 40, and the other end of the water supply pipe 40 is connected to a purification tank or water tank, so that the water to be purified flows into the reaction tank 10 through the inlet. Since the ozone generator 20 can release ozone into the reaction tank 10, the ozone can mix with the water in the reaction tank 10. This allows the ozone to inhibit and destroy algae and shellfish and other microorganisms in the raw water by utilizing its strong oxidizing properties, preventing them from multiplying in large quantities in subsequent processes and causing adverse effects. At the same time, it can also partially oxidize natural organic matter such as humic acid in the water, reducing the possibility of them reacting with disinfectants such as chlorine to produce disinfection byproducts such as trihalomethanes, thereby purifying the water in the reaction tank 10.

[0028] Compared to traditional chemical oxidation methods that commonly use chlorine-based disinfectants such as potassium permanganate and sodium hypochlorite, which easily react with parent organic matter to produce disinfection byproducts such as chloroform and carbon tetrachloride, this method not only disinfects water sources but also reduces the generation of disinfection byproducts, resulting in purified water sources with higher safety for use.

[0029] Furthermore, since there is a probability of shellfish and algae growth during the transportation of water through the water pipe 40, this embodiment installs a disinfectant storage tank 30 at the water pipe 40. When the water that has been initially purified in the reaction tank 10 is transported to the outside through the water pipe 40, sodium hypochlorite solution can be added to the water pipe 40 again through the disinfectant storage tank 30. This reduces the probability of shellfish or other microorganisms growing and further disinfects the water source a second time with the sodium hypochlorite solution. As a result, the water source that is finally delivered to the water purification plant or domestic water supply is purified a second time before being used by people, which greatly improves the safety of water use.

[0030] Specifically, the ozone generator 20 in this embodiment can be an existing tubular ozone generator 20 or a plate ozone generator 20. During assembly, the ozone generator 20 can be fixed above or inside the reaction tank 10 by a support base or mounting base or other installation structure. Then, the outlet of the ozone generator 20 is connected to the reaction tank 10 by a pipe or jet, so that ozone can be discharged into the reaction tank 10.

[0031] More specifically, in this embodiment, the outlet of the disinfectant storage tank 30 can be connected to the water supply pipe 40 through a pipeline, so that sodium hypochlorite solution can be added into the water supply pipe 40 for secondary purification of the water source.

[0032] The entire water purification process reduces the overall dosage of chlorine-based disinfectants, allowing the water source to be purified a second time while also reducing the probability of disinfection byproducts and improving water safety.

[0033] Furthermore, the reaction tank 10 is also equipped with a number of ultraviolet lamps 50, which are distributed at intervals in the reaction tank 10.

[0034] Specifically, because several ultraviolet lamps 50 are installed, the ozone is irradiated by the ultraviolet light emitted by multiple ultraviolet lamps 50 simultaneously. After the ozone molecules absorb photon energy, they decompose and produce hydroxyl radicals, which have a stronger oxidizing ability than ozone. This more effectively degrades pollutants such as organic matter and algae in the water, improves the efficiency and effect of the oxidation reaction, and further reduces the content of organic matter in the pre-disinfection byproducts. In addition, the oxidation reaction rate is faster under ultraviolet irradiation, which can better decompose some recalcitrant organic matter, thereby improving the overall treatment capacity of the reaction tank 10 for raw water and improving water quality.

[0035] More specifically, because the ultraviolet light of UV50 has a bactericidal effect, it can destroy microorganisms (such as bacteria, viruses, algae, etc.), causing them to lose their ability to reproduce and survive, thereby achieving the purpose of sterilization and disinfection. Therefore, by combining the oxidative disinfection effect of UV50 with that of ozone, a dual disinfection mechanism is formed, which can more thoroughly kill harmful microorganisms in the raw water, ensure that the microbiological indicators of the raw water meet the requirements, and further improve the safety of water use.

[0036] It should be noted that the ultraviolet lamp 50 in this embodiment can be an existing ultraviolet lamp, such as a high-pressure ultraviolet mercury lamp, an ultraviolet iron lamp, or a sterilization lamp.

[0037] Furthermore, the disinfection assembly also includes a metering pump 31 and a guide pipe. One end of the guide pipe is connected to the disinfectant storage tank 30, and the other end of the guide pipe is connected to the water delivery pipe 40. The metering pump 31 is located on the guide pipe and is used to drive the sodium hypochlorite solution to flow through the guide pipe into the water delivery pipe 40.

[0038] Based on this structure, the sodium hypochlorite solution in the disinfectant storage tank 30 can be delivered into the delivery pipe through the guide pipe. Due to the metering pump 31 on the guide pipe, the delivery volume of sodium hypochlorite solution per unit time is controlled by the parameters set by the metering pump 31. This allows for the accurate delivery of the required dose of sodium hypochlorite solution by adjusting the operating parameters of the metering pump 31, such as the stroke frequency and stroke length, whether treating a small amount or a large amount of water. This ensures that the concentration of sodium hypochlorite solution in the water is maintained within a suitable range, effectively killing bacteria and viruses in the water without adversely affecting the water quality due to excessive sodium hypochlorite solution, thus guaranteeing the stability and safety of the effluent water quality.

[0039] Preferably, the metering pump 31 in this embodiment can be an existing electromagnetically driven metering pump 31, screw metering pump 31, or plunger metering pump 31, etc.

[0040] In addition, the disinfection assembly also includes a flow meter 32, which is installed on the guide pipe and located between the metering pump 31 and the water supply pipe 40. The flow meter 32 displays the flow data of sodium hypochlorite solution in the guide pipe in real time, allowing operators to intuitively understand the delivery status of sodium hypochlorite solution and to keep track of the supply status of sodium hypochlorite solution during the disinfection process.

[0041] Specifically, if the flow meter 32 displays a flow rate lower than the set value, the metering pump 31 can automatically increase its output; conversely, it can decrease its output. In this way, by using the metering pump 31 in conjunction with the flow pump to monitor and control the flow rate of the sodium hypochlorite solution, the dosage of sodium hypochlorite solution entering the water supply pipe 40 can be kept stable, thereby ensuring a uniform disinfection effect on the raw water and avoiding incomplete or excessive disinfection due to fluctuations in the flow rate of the sodium hypochlorite solution. This indirectly reduces the generation of disinfection byproducts and improves water safety.

[0042] Furthermore, the reaction tank 10 has a water storage chamber, and a partition is provided in the water storage chamber. The partition separates the water storage chamber into a reaction chamber 11 and a water collection chamber 12. The water inlet is connected to the reaction chamber 11, and the water outlet is located in the water collection chamber 12. An overflow hole is provided on the partition, which is used to guide the water flow to the water collection chamber 12.

[0043] Specifically, the water storage chamber is divided into two parts by a partition to form a reaction chamber 11 and a water collection chamber 12. When the raw water enters the reaction chamber 11 from the inlet, it needs to go through a certain path and time before it can enter the water collection chamber 12 through the overflow hole. This ensures that the water has enough residence time in the reaction chamber 11, so that oxidation reactions can be carried out more fully, thereby better decomposing recalcitrant organic matter and improving water quality.

[0044] In addition, the baffles and overflow holes can guide the water flow in a specific direction and speed. For example, by reasonably designing the size, number and position of the overflow holes, the flow rate and flow velocity of the water from the reaction chamber 11 into the water collection chamber 12 can be controlled, so that the water flow forms a more ideal flow state in the reaction tank 10, avoiding short-circuiting, eddies and other conditions that are not conducive to reaction and sedimentation, thereby improving the treatment efficiency of the reaction tank 10.

[0045] More specifically, a filter plate is installed at the overflow hole, which covers the overflow hole. The filter plate can effectively intercept suspended particles, sediments, flocculent matter and other impurities in the water in the reaction chamber 11, preventing them from entering the water collection chamber 12 through the overflow hole. This avoids these impurities accumulating in the water collection chamber 12 or entering the subsequent treatment stage with the water flow, further purifying the water source and improving the water quality.

[0046] In addition, the filter plate can prevent larger particles of impurities from entering the water collection chamber 12 and causing blockage, wear or damage to related equipment such as water pump 41 and pipes in the water collection chamber 12, thereby extending the service life of the equipment and reducing equipment maintenance costs.

[0047] It should be noted that the filter plate can be an existing stainless steel filter plate or a PP plastic filter plate, etc.

[0048] Furthermore, it also includes a water pump 41, which is mounted on the water supply pipe 40 and connected to the water supply pipe 40.

[0049] Specifically, by setting up a water pump 41 to provide a power source, the water in the reaction tank 10 can be circulated and transported to the outside (such as a water purification plant) through the outlet.

[0050] In addition, the water pump 41 can also interact with the metering pump 31. The metering pump 31 is responsible for accurately dispensing the sodium hypochlorite solution, while the water pump 41 drives the water flow, so that the sodium hypochlorite solution can be quickly and evenly diffused in the water flow, thereby achieving a better disinfection effect. The two working together can ensure that the appropriate amount of sodium hypochlorite solution can be accurately mixed with water under different water volume conditions.

[0051] Furthermore, the ozone generating assembly also includes a jet mixer 21, which is connected to the water supply pipe 40 and the ozone generator 20 via pipes.

[0052] Specifically, compared to ozone being directly emitted into water, where the gas may rise rapidly in the form of large bubbles, resulting in limited contact time and area with water and uneven mixing, this embodiment uses a jet mixer 21. One end of the jet mixer 21 is connected to the water supply pipe 40 through a pipe, allowing water from the water supply pipe 40 to be diverted into the jet mixer 21. When water passes through the jet mixer 21, it forms a high-speed jet, generating negative pressure in the jet area. This draws the ozone gas generated by the ozone generator 20 into the jet mixer 21. Under the action of the high-speed water flow, the ozone gas is rapidly dispersed into tiny bubbles, which fully contact and mix with the water to form ozone water.

[0053] The mixed ozone water is then discharged into the reaction tank 10. Since the ozone has been fully mixed with the water in the jet mixer 21, it can be more evenly distributed in the water after entering the reaction tank 10, so that the ozone reacts more fully with the water in the reaction tank 10. This means that ozone molecules have more opportunities to collide with pollutant molecules, thereby oxidizing and decomposing pollutants more quickly and improving water purification efficiency.

[0054] It should be noted that the jet mixer 21 in this embodiment can be an existing gas jet mixer.

[0055] Furthermore, the ozone generating assembly also includes a mixing reactor 22 and an emitter 23. The mixing reactor 22 is connected to the jet mixer 21, one end of the emitter 23 is connected to the mixing reactor 22, and the other end of the emitter 23 is connected to the reaction tank 10.

[0056] Based on this structure, by connecting the mixing reactor 22 and the jet mixer 21, after the ozone and water are initially mixed in the jet mixer 21, they can enter the mixing reactor 22 for secondary mixing. The mixing reactor 22 provides a more complex flow field and a longer residence time, making the mixing of ozone and water more uniform and complete, allowing the reaction to proceed more thoroughly and avoiding uneven local concentrations.

[0057] Then, the ozone water that has been fully mixed and reacted in the mixing reactor 22 is released into the reaction tank 10 in a suitable manner and at a suitable rate through the release device 23. For example, the ozone water is distributed in the form of smaller bubbles or more uniform water flow to increase the contact area and contact time between ozone and the water in the reaction tank 10, so that ozone can participate in the reaction with pollutants as much as possible, reduce the loss caused by ozone directly escaping from the water surface, and thus improve the utilization rate of ozone.

[0058] It should be noted that the mixing reactor 22 can be an existing stirred mixing reactor or a static mixing reactor, while the release device 23 can be a microporous aerator release device, which is made of porous materials such as ceramics or corundum. When the ozone water passes through the microporous release device, it is dispersed into tiny bubbles and released into the reaction tank 10, increasing the contact area and time between ozone and water. Of course, other types of release devices can also be selected.

[0059] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
