Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a water treatment device for sterilization and deodorization. Background Technology

[0002] The booming development of aquaculture has met the growing global demand for high-quality protein. However, high-density intensive farming has exacerbated eutrophication, leading to two core water quality problems: the accumulation of earthy-smelling substances and the proliferation of pathogenic microorganisms, severely hindering the healthy development of the industry. In aquaculture waters, volatile organic compounds produced by the metabolism of certain cyanobacteria (such as Anabaena and Oscillatoria) and actinomycetes, primarily geosmin (GSM) and 2-methylisoborneol (MIB), are the root cause of unpleasant earthy or musty odors in aquatic products. These substances have extremely low sensory thresholds and are easily absorbed by fish through their gills and skin, accumulating in their muscle and fatty tissues. Even after the aquaculture process ends, the odor is difficult to completely remove through routine washing or cooking, significantly reducing the market acceptance and economic value of aquatic products, resulting in substantial economic losses.

[0003] Aquaculture water bodies are breeding grounds for various pathogenic microorganisms (bacteria, viruses, parasites), and disease outbreaks can lead to large-scale mortality of farmed organisms. Commonly used water treatment methods are significantly insufficient in efficiently and safely removing earthy odors, and finding efficient, low-toxicity, and residue-free physical or physicochemical synergistic sterilization methods is an urgent need for the industry. Utility Model Content

[0004] Therefore, the purpose of this utility model is to overcome the obvious shortcomings of commonly used water treatment methods in efficiently and safely removing earthy odors, and to provide a water treatment device for sterilization and odor removal. This application integrates the functions of degrading earthy odors and highly efficient sterilization, achieving broad-spectrum sterilization, effectively killing or inactivating various pathogenic microorganisms in water, and simultaneously rapidly and thoroughly decomposing and removing trace amounts of but significantly harmful GSM and MIB. The treatment process does not produce toxic byproducts and leaves no harmful residues, ensuring the safety of aquatic products and environmental friendliness.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A water treatment device for sterilization and deodorization includes:

[0007] Slightly acidic electrolyzed water generator: used to convert water to be treated into slightly acidic electrolyzed water;

[0008] Tank body: It is equipped with an inlet and an outlet, the inlet being connected to the slightly acidic electrolyzed water generator and used to introduce the treated water;

[0009] Filter layer: Located inside the tank and used to filter the treated water introduced through the inlet;

[0010] Ultraviolet disinfection mechanism: located inside the tank and used for irradiating the water;

[0011] Water disturbance mechanism: includes a stirring paddle with one end located inside the tank, and a drive device connected to the other end of the stirring paddle and located outside the tank;

[0012] Online available chlorine monitor: The detection end is located inside the tank and is used to monitor the available chlorine concentration in the water.

[0013] This application involves using a slightly acidic electrolyzed water generator to process water containing bacteria and algae into slightly acidic electrolyzed water. The treated water enters the tank through the inlet, where a filter layer removes large impurities before the water flows into the tank. Once a certain concentration is reached, water injection is stopped. The ultraviolet disinfection and water agitation mechanisms are then activated. Ultraviolet light decomposes hypochlorous acid, the main component of the slightly acidic electrolyzed water, into chlorine and hydroxyl radicals, which have strong oxidizing properties. The water agitation mechanism causes the water in the tank to circulate slowly, which helps to reduce and kill odor-causing substances, bacteria, and algae. After a period of reaction, the ultraviolet disinfection mechanism is turned off, but the water agitation mechanism can remain on temporarily to maintain water circulation and allow excess available chlorine in the water to decompose slowly. An online available chlorine monitor is activated to monitor the available chlorine concentration in real time. Once the available chlorine concentration drops below a safe level, the water agitation mechanism and the online available chlorine monitor are turned off, and the treated water can then be discharged through the outlet, completing the sterilization and deodorization of the water treatment process.

[0014] The main purpose of this application in killing and reducing bacteria and odors is to use ultraviolet light irradiation to decompose hypochlorous acid (HClO), the main component of slightly acidic electrolyzed water, into chlorine free radicals and hydroxyl free radicals. These free radicals have strong oxidizing properties and can degrade odors while killing bacteria. If slightly acidic electrolyzed water is not prepared, relying solely on ultraviolet light irradiation can only achieve limited sterilization, and has almost no reduction effect on geosmin (GSM) and 2-methylisoborneol (MIB). This application presents a novel water treatment device that integrates the degradation of earthy odor with highly efficient sterilization. It can achieve broad-spectrum sterilization, effectively killing or inactivating various pathogenic microorganisms in the water. At the same time, it can quickly and thoroughly decompose and remove trace amounts of GSM and MIB, which are significantly harmful. The treatment process does not produce toxic byproducts, does not affect the health of aquatic organisms, and leaves no harmful residues, ensuring the safety of aquatic products and environmental friendliness. Compared with existing odor treatment and sterilization equipment, it is not only simple in structure, low in cost, easy to operate, and environmentally friendly, but also has better treatment effect and can be applied to various water treatment scenarios.

[0015] Furthermore, the top of the tank is open and equipped with a removable tank cover, and the water agitation mechanism is connected to the tank cover. Designing the tank as an open structure facilitates internal maintenance, making it easier to clean and repair the tank's interior. Simultaneously, placing the water agitation mechanism on the removable tank cover allows for effective detachment of the mechanism from the tank for cleaning and maintenance after the tank cover is removed, simplifying the internal structure of the tank and facilitating internal cleaning and repair.

[0016] Furthermore, the tank lid is also equipped with a manual cleaning port. This port allows personnel to easily observe the buildup of impurities in the filter layer inside the tank and clean them as needed, improving the tank's continuous operating capacity and ensuring water treatment efficiency.

[0017] Furthermore, a drain outlet is provided at the bottom of the tank, and the bottom of the tank is funnel-shaped, with the drain outlet located at the center of the funnel-shaped bottom. The drain outlet can be opened or closed according to the actual sedimentation of impurities, and the funnel-shaped bottom of the tank facilitates the cleaning and discharge of impurities.

[0018] Furthermore, the height of the inlet is higher than the height of the outlet, and the filter layer is located between the inlet and the outlet.

[0019] Furthermore, the stirring paddle includes a stirring shaft and stirring blades evenly distributed along the axis of the stirring shaft, and the output end of the driving device is connected to the stirring shaft.

[0020] Furthermore, the stirring blade includes a bushing fitted onto the stirring shaft, and a plurality of fan blades evenly distributed along the circumference of the bushing, wherein the plurality of fan blades are arranged in an umbrella shape on the bushing. The umbrella-shaped fan blades occupy a smaller circumferential area, creating a good disturbance effect while optimizing the spatial layout inside the tank and increasing the space available for the ultraviolet disinfection mechanism.

[0021] Furthermore, each of the fan blades is tilted at a certain angle relative to the horizontal plane. This tilting reduces water resistance during rotation, decreases turbulence, ensures slow, circulating water flow, and better helps to reduce and kill odor-causing substances, bacteria, and algae in the water.

[0022] Furthermore, the ultraviolet disinfection mechanism includes several sets of ultraviolet lamp columns surrounding the stirring blade, each ultraviolet lamp column being covered with a quartz tube lamp cover. Protected by the quartz tube lamp cover, the ultraviolet lamp columns are isolated from the water. The ultraviolet light passing through the quartz tube lamp cover decomposes hypochlorous acid, the main component of the slightly acidic electrolyzed water, into chlorine free radicals and hydroxyl free radicals, which have strong oxidizing properties.

[0023] Furthermore, it also includes a level gauge with its measuring end located inside the tank. Adding a level gauge allows for the detection of water levels within the tank, automatically introducing water and stopping operations without requiring real-time manual monitoring, thus improving the level of automation.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This application transforms water containing bacteria and algae into slightly acidic electrolyzed water using a slightly acidic electrolyzed water generator. Utilizing ultraviolet irradiation from an ultraviolet disinfection unit, the main component of the slightly acidic electrolyzed water, hypochlorous acid (HClO), decomposes into chlorine free radicals and hydroxyl free radicals. These free radicals possess strong oxidizing properties, degrading odor substances while simultaneously killing bacteria. This application presents a novel water treatment device integrating the degradation of earthy odors with highly efficient sterilization. It achieves broad-spectrum sterilization, effectively killing or inactivating various pathogenic microorganisms in the water. Simultaneously, it can rapidly and thoroughly decompose and remove trace amounts of significantly harmful GSM and MIB. The treatment process does not produce toxic byproducts, does not affect the health of aquatic organisms, and leaves no harmful residues, ensuring the safety of aquatic products and environmental friendliness. Compared to existing odor treatment and sterilization equipment, this device is not only simple in structure, low in cost, environmentally friendly, and easy to operate, but also has better treatment effects and can be applied to various water treatment scenarios.

[0034] Example 1

[0035] like Figure 1 As shown, this embodiment provides a water treatment device for sterilization and deodorization, including:

[0036] Slightly acidic electrolyzed water generator 1: Used to convert water to be treated into slightly acidic electrolyzed water;

[0037] Tank 2: It is equipped with an inlet 21 and an outlet 22. The inlet 21 is connected to the slightly acidic electrolyzed water generator 1 and is used to introduce the treated water.

[0038] Filter layer 3: Located inside the tank 2 and used to filter the treated water introduced through the inlet 21;

[0039] Ultraviolet disinfection unit 4: located inside tank 2 and used for irradiating water;

[0040] Water disturbance mechanism 5: includes a stirring paddle 51 with one end located inside the tank 2, and a drive device 52 connected to the other end of the stirring paddle 51 and located outside the tank 2;

[0041] Online available chlorine monitor 6: The detection end is located inside tank 2 and is used to monitor the available chlorine concentration in the water.

[0042] In this embodiment, the slightly acidic electrolyzed water generator 1 is a purchased, existing device. The principle of slightly acidic electrolyzed water preparation is to apply a direct current voltage to a diaphragm-free electrolytic cell to electrolyze a mixture of dilute salt and dilute hydrochloric acid solutions, producing slightly acidic water with a specific pH value, oxidation-reduction potential (ORP), and effective chlorine concentration (ACC). A flow pump is mainly used to pump water containing odorous substances, bacteria, and algae, along with the electrolyte, into the electrolytic cell. Under the action of direct current, chlorides and hydroxides near the anode lose electrons to form hypochlorite (ClO). - And substances such as hypochlorous acid (HClO).

[0043] The main electrode reactions are as follows:

[0044] Anode: H₂O → 1 / 2O₂ + 2H₂O + + 2e - ;

[0045] 2Cl - → Cl2 + 2e - ;

[0046] Cl2 + H2O → HCl + HClO;

[0047] In this embodiment, the online available chlorine monitor 6 is an existing, purchased device. The online available chlorine monitor 6 is an automated analytical device capable of real-time, continuous monitoring of the concentration of "available chlorine" in water. It uses a sensor to directly contact the water sample, continuously detecting the available chlorine concentration. The data is displayed in real-time on a screen and is applied to scenarios requiring disinfection using chlorine-containing disinfectants such as sodium hypochlorite or chlorine gas, ensuring that disinfection effectiveness meets standards.

[0048] The working principle of this application is as follows: Water containing bacteria and algae is processed into slightly acidic electrolyzed water using a slightly acidic electrolyzed water generator 1. The treated water enters the tank 2 through the inlet 21. A filter layer 3 filters out larger impurities before the water flows into the tank 2. Once a certain concentration is reached, water injection stops. The ultraviolet disinfection mechanism 4 and the water agitation mechanism 5 are activated. Ultraviolet light decomposes hypochlorous acid, the main component of the slightly acidic electrolyzed water, into chlorine free radicals and hydroxyl free radicals, which have strong oxidizing properties. The water agitation mechanism 5 causes the water inside the tank to circulate slowly. Flowing water helps to better reduce and kill odor substances, bacteria, and algae in the water. After a period of reaction, the ultraviolet disinfection mechanism 4 is turned off, while the water disturbance mechanism 5 can be left on temporarily to keep the water circulating and allow excess available chlorine in the water to decompose slowly. The online available chlorine monitor 6 is turned on to monitor the concentration of available chlorine in the water in real time. Once the concentration of available chlorine in the water drops below the safe value, the water disturbance mechanism 5 and the online available chlorine monitor 6 are turned off. Then the treated water can be discharged through the outlet 22, completing the sterilization and deodorization of the water treatment.

[0049] like Figure 2 As shown, the top of the tank 2 is open and equipped with a removable tank cover 23, and the water agitation mechanism 5 is connected to the tank cover 23. Designing the tank 2 as an open structure facilitates maintenance work inside the tank 2, making it convenient to clean and repair the interior. Simultaneously, placing the water agitation mechanism 5 on the removable tank cover 23 allows for effective detachment of the water agitation mechanism 5 from the tank 2 for cleaning and maintenance after removing the tank cover 23, simplifying the internal structure of the tank 2 and facilitating cleaning and repair.

[0050] like Figure 3 As shown, the tank cover 23 is also provided with a manual cleaning port 24. The manual cleaning port on the tank cover 23 allows personnel to easily observe the accumulation of impurities in the filter layer 3 inside the tank 2, and to clean the impurities in a timely manner, thereby improving the continuous working capacity of the tank 2 and ensuring water treatment efficiency.

[0051] like Figure 2 As shown, a drain port 25 is also provided at the bottom of the tank body 2. The bottom of the tank body 2 is funnel-shaped, and the drain port 25 is located at the center of the funnel-shaped bottom of the tank body 2. The drain port 25 can be opened or closed according to the actual sedimentation of impurities, and the funnel-shaped bottom of the tank body 2 facilitates the cleaning and discharge of impurities.

[0052] In this embodiment, the height of the inlet 21 is higher than the height of the outlet 22, and the filter layer 3 is located between the inlet 21 and the outlet 22.

[0053] In this embodiment, the inlet 21 is located at a high position on the side wall of the tank 2, and the outlet 22 is located at a low position on the side wall of the tank 2. The filter layer 3 is a metal filter screen. The filter layer 3 is closely attached to the inside of the tank 2 to isolate the inlet 21 and the outlet 22. The filter layer 3 is set close to the inlet 21 to facilitate cleaning of the filter layer 3 through the manual cleaning port 24 on the tank cover 23.

[0054] The advantage of this application is that the killing and reduction of bacteria and odor substances is mainly achieved by using ultraviolet light irradiation to decompose hypochlorous acid (HClO), the main component of slightly acidic electrolyzed water, into chlorine free radicals and hydroxyl free radicals. These free radicals have strong oxidizing properties and can degrade odor substances while killing bacteria. If slightly acidic electrolyzed water is not prepared, relying solely on ultraviolet light irradiation can only achieve limited sterilization, and has almost no reduction effect on geosmin (GSM) and 2-methylisoborneol (MIB). This application presents a novel water treatment device that integrates the degradation of earthy odor with highly efficient sterilization. It can achieve broad-spectrum sterilization, effectively killing or inactivating various pathogenic microorganisms in the water. At the same time, it can quickly and thoroughly decompose and remove trace amounts of GSM and MIB, which are significantly harmful. The treatment process does not produce toxic byproducts, does not affect the health of aquatic organisms, and leaves no harmful residues, ensuring the safety of aquatic products and environmental friendliness. Compared with existing odor treatment and sterilization equipment, it is not only simple in structure, low in cost, environmentally friendly, and easy to operate, but also has better treatment effect and can be applied to various water treatment scenarios.

[0055] Example 2

[0056] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0057] like Figure 2 As shown, the stirring paddle 51 includes a stirring shaft 511, stirring blades evenly distributed along the axis of the stirring shaft 511, and the output end of the driving device 52 is connected to the stirring shaft 511.

[0058] like Figure 4 As shown, the stirring blade includes a bushing 513 fitted onto the stirring shaft 511, and several fan blades 514 evenly distributed along the circumference of the bushing 513. The fan blades 514 are arranged in an umbrella shape on the bushing 513. The umbrella-shaped fan blades 514 occupy a smaller circumferential area, which not only creates a good disturbance effect but also optimizes the spatial layout inside the tank 2 and increases the space available for the ultraviolet disinfection mechanism 4.

[0059] like Figure 4 As shown, each fan blade 514 is tilted at a certain angle relative to the horizontal plane. The tilt of the fan blade 514 relative to the horizontal plane at a certain angle can reduce the water resistance during rotation, reduce the turbulence formed by the water flow, ensure the slow circulation of water, and better help to reduce and kill odor substances, bacteria and algae in the water.

[0060] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0063] like Figure 2 As shown, the ultraviolet disinfection mechanism 4 includes several sets of ultraviolet lamp columns 41 surrounding the stirring blade, and each ultraviolet lamp column is covered with a quartz tube lamp cover 42. Under the protection of the quartz tube lamp cover 42, the ultraviolet lamp columns 41 are isolated from the water. The ultraviolet light passing through the quartz tube lamp cover 42 can decompose hypochlorous acid, the main component of slightly acidic electrolyzed water, into chlorine free radicals and hydroxyl free radicals, which have strong oxidizing properties.

[0064] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0065] Example 4

[0066] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0067] like Figure 2 As shown, it also includes a level gauge 7 with its measuring end located inside the tank 2.

[0068] The other structures and principles of this embodiment are the same as those of Embodiment 1.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
