[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, further detailed description of the embodiments of the present disclosure will be made below in combination with examples and drawings, and the schematic embodiments of the present disclosure and the description thereof are only used to explain the embodiments of the present disclosure, and do not limit the embodiments of the present disclosure.

[0024] As shown in Figure 1 and Figure 2 , the dissolved air nano oxygenation device used in the basin management of the present application includes a lifting water pump 1, a lifting pipeline 2, a water collecting tank 3, a booster water pump 4, a high-pressure water pipe 5, a dissolved air pressure tank 6, an air compressor 7, an air pipe 8, and a nano dissolved oxygen water release pipe 9. These components work organically to solve the dissolved oxygen problem in basin management and effectively improve water quality.

[0025] Specifically, the lifting water pump 1 is arranged near the river. Its function is to continuously pump the river water from a low place or a long distance to a water collecting tank 3 above through a lifting pipeline 2. The water collecting tank 3 is used to temporarily store the water delivered to make the water flow more evenly and smoothly into the subsequent treatment unit. Next, the booster water pump 4 located after the water collecting tank 3 can give the water a secondary boost, which not only increases the water pressure but also ensures that the fluid in the entire system has enough kinetic energy to complete the next process, and then through a high-pressure water pipe 5 is directly connected to a key part, the dissolved air pressure tank 6. At the same time, there is an important equipment, the air compressor 7, which provides essential support for the dissolved air step throughout the process. The air is sucked into the air compressor 7 and after compression and pressure increase, it also enters the dissolved air pressure tank 6 along the air pipe 8 laid separately. Inside the pressure vessel, under the condition of high pressure, the input from the booster water pump 4 and the air compressor 7 interacts with each other, so that the gas molecules can be dissolved into the water in the micron or even smaller size, and the final solution is called nano dissolved air water. The last step is the nano dissolved oxygen water release pipe 9 installed at the downstream position, which is used to accurately output the treated high-dissolved oxygen water body to the original river.

[0026] In one embodiment, the water-lifting pump 1 of the dissolved air nanometer oxygenation device used in the watershed management of the present application is connected to the water collection tank 3 through the lifting pipe 2. Specifically, the water-lifting pump 1 is installed at a lower position to extract water from the water source area. The water-lifting pump 1 can effectively pump river water containing pollutants or insufficient dissolved oxygen into the lifting pipe 2. This section of pipe serves as an intermediary structure to establish an effective delivery channel between the water-lifting pump 1 and the water collection tank 3, ensuring that the water flow can be stably transferred from a low position to a high position.

[0027] In this design, the lifting pipe 2 is made of a strong and corrosion-resistant material to avoid damage caused by high pressure or poor water quality. The lifting pipe 2 is not only a simple transportation path, but also an important component of the entire device, and its impact on water flow pressure loss and transmission efficiency needs to be considered. For example, in actual operation, the pipe can be made of stainless steel material and appropriate connecting fittings can be used to achieve seamless connection.

[0028] Specifically, the water-lifting pump 1 is first fixedly installed on a base support to ensure that the pump body is stable and does not vibrate to affect operation. Then, a pre-prepared lifting pipe 2 is accurately installed and connected to the water outlet on the pump body; subsequently, the other end is tightly fitted with the water collection tank 3 located at a higher position, thereby forming a complete flow path to allow the treated dissolved nanometer oxygen to be smoothly injected into the water body to be treated.

[0029] In one embodiment, the booster water pump 4 of the dissolved air nanometer oxygenation device used in the watershed management of the present application is configured with the relevant pipe, and the booster water pump 4 connects the water collection tank 3 and the dissolved air pressure tank 6 through the high-pressure water pipe 5. This design makes the dissolved air process more efficient and ensures that the nanometer-level oxygen can be fully dissolved in the water to be treated. The water collection tank 3 is used to receive the water flow that needs to be treated for oxygenation after preliminary purification or collection. Then, the water flow is introduced into the booster water pump 4 located downstream of the water collection tank 3. The function of the water pump is not only to increase the pressure of the water body, but also to ensure that the water body flows stably and continuously. Subsequently, the water flow after pressure boosting is delivered to a specific area in the dissolved air pressure tank 6 through the specially designed high-pressure water pipe 5.

[0030] The material and structural design of the high-pressure water pipe 5 needs to have the ability to withstand high pressure to avoid rupture or other forms of failure, ensuring long-term stable operation of the system. Specifically, in one embodiment, to achieve this pressurization and transmission function, a steel pipe or a composite material pipe with good corrosion resistance and pressure-bearing performance can be selected as the medium conveying channel connecting the water collecting tank 3 and the dissolved air pressure tank 6. For example, a high-pressure hose with a reinforced fiber wrapping layer is selected, and high-strength sealing materials are used for the interface parts. In this way, good connection sealing can be maintained even in a high-pressure environment, ensuring the safe and reliable working state of the equipment.

[0031] In one embodiment, the air compressor 7 of the dissolved air nano oxygenation device used in the watershed management of the present application is connected to the dissolved air pressure tank 6 through the air pipe 8. Specifically, the device includes an air compressor 7 for compressing air and a dissolved air pressure tank 6 for storing and processing dissolved air water. The air compressor 7 is installed on the base platform of the entire device structure and is fixed by a sturdy support to ensure stability. After the air is output from the air compressor 7, it is purified and dried to ensure that the gas quality meets the process requirements, and then it is delivered to the dissolved air pressure tank 6 through a specially designed air pipe 8. The air pipe 8 has corrosion resistance and pressure resistance, and has a smooth inner wall inside to reduce air resistance. In addition, reliable seals are used at the pipe connections to prevent leakage.

[0032] One end of the air pipe 8 is firmly connected to the outlet end of the air compressor 7, and the other end is accurately connected to the air inlet of the dissolved air pressure tank 6. Standard interfaces are used at the connection points between the two to ensure safety and sealing. To facilitate maintenance and inspection, manual or electric valves are provided on the air pipe 8, which can be used to cut off the air path for individual operation when needed. This design not only ensures smooth communication between the air compressor 7 and the dissolved air pressure tank 6, but also provides convenient conditions for subsequent operation.

[0033] For example, to ensure that air can be stably input into the dissolved air pressure tank 6, the air compressor 7 is equipped with appropriate adjustment devices to control the output air volume; and the air pipe 8 is installed according to the preset path, extending from the exhaust side of the air compressor 7 to the designated inlet of the dissolved air pressure tank 6 at the top, achieving effective gas delivery. In the entire process, all pipe interfaces are strictly sealed to prevent any external impurities from entering the system and interfering with normal operation. At the same time, considering the compactness and aesthetics of the system, all pipes and connections are arranged as simply and orderly as possible, reducing the occupied space while also improving the overall appearance.

[0034] In one embodiment, the air dissolved gas pressure tank 6 of the dissolved gas nanometer oxygenation device used in the basin management of the present application is connected with the nanometer dissolved oxygen water release pipe 9. This device realizes high-efficiency oxygen dissolution operation through unique structural design, and is particularly suitable for water quality purification and management of natural basins such as rivers and lakes.

[0035] Specifically, the air dissolved gas pressure tank 6 is one of the key components in the entire system, and the inside of the tank makes gas dissolve in water efficiently through a specific pressure environment. In this embodiment, the air dissolved gas pressure tank 6 is located at the core position of the entire device and is directly associated with multiple components to form a high-efficiency circulating treatment system. The pressure tank is designed to withstand and maintain a high internal pressure, providing a stable gas-liquid mixing environment while ensuring safety. In order to achieve higher oxygen dissolution efficiency, multiple structural layers are arranged inside the pressure tank, which enhances the contact time and area of gas and water, further promoting the gas dissolution process.

[0036] Then, the pressure tank outlet is connected to the nanometer dissolved oxygen water release pipe 9, which is specially designed for transporting oxygen-containing water fully saturated. The material and inner diameter of the nanometer dissolved oxygen water release pipe 9 are carefully selected to minimize fluid resistance and prevent oxygen from escaping during transportation. In addition, the terminal of the pipe is equipped with a series of fine spray heads or pores for uniformly dispersing oxygen-rich water into the target water body. In terms of connection, a detachable sealed interface is adopted, which not only simplifies maintenance and repair work, but also enhances the reliability and service life of the system.

[0037] For example, in actual application, ordinary water is injected into the air dissolved gas pressure tank 6 by a high-pressure water pump, and a certain amount of compressed air or other suitable gas has been pre-filled in the tank. The forced gas-liquid mixing reaction is carried out in this closed space. The generated ultra-micro bubble water is then transported from the end of the tank body to the connected nanometer dissolved oxygen water release pipe 9, and finally enters the water environment to be treated through the precisely arranged discharge port, completing the entire oxygenation process.

[0038] In one embodiment, as shown in Figure 3 The flow regulating valve 10 is provided between the lifting water pump 1 and the water collecting tank 3 of the dissolved gas nanometer oxygenation device used in the basin management of the present application, which is used to adjust the amount of water entering the water collecting tank 3, and to ensure the stability of the water amount. This design can effectively control the amount of water flowing through the system, so that the device can more efficiently introduce dissolved gas and nanometer oxygen into the water body. Through precise flow control, the stability of the water flow is ensured, and unnecessary energy waste and equipment wear and tear are reduced.

[0039] The specific structure of the flow regulating valve 10 includes a valve with adjustable opening degree, which can be adjusted by manual or automatic control system. The flow regulating valve 10 is installed at the connection between the lifting water pump 1 and the water collecting tank 3 to ensure that it can directly act on the water flow before entering the water collecting tank 3. In order to realize higher automation and accuracy, the device can be equipped with sensing elements to monitor the actual flow and feedback to the control system in real time, so as to realize adaptive adjustment function. This design not only improves the reliability and efficiency of the system, but also simplifies the operation process in practical application and reduces the need for human intervention.

[0040] For example, the flow parameter between the outlet of the lifting water pump 1 and the inlet of the water collecting tank 3 can be monitored in real time by installing sensors. When the flow exceeds the preset value, the controller will issue instructions to adjust the opening degree of the flow regulating valve 10 to ensure that the water flow meets the expected standard. This makes the system maintain stable working state even in the case of fluctuation of water source flow.

[0041] Reference Figure 4 In one embodiment, a filter screen 11 is provided at the connection between the lifting water pump 1 and the lifting pipeline 2 of the dissolved air nanometer oxygenation device used in the basin management of the present application. The filter screen 11 filters out larger suspended solids in river water to prevent impurities from blocking the pipeline and improve the operating efficiency of the system. In order to ensure that the device can effectively operate in complex river environment, the position of key components and the overall structural layout need to be specially considered in the design.

[0042] In this specific design, the filter screen 11 is installed at the connection between the lifting water pump 1 and the lifting pipeline 2. This position selection can effectively trap large particles in river water, reducing the possibility of their entering the subsequent components with water flow, thereby ensuring the stability and long-term effectiveness of the entire equipment. Specifically, this filtering device is not a separate element, but is embedded in the water flow path as an integrated part of the lifting system. Through reasonable structural design, it is closely attached to the intersection of pump and pipeline to achieve high-efficiency blocking effect without increasing additional space requirements or operation complexity. This design optimizes the original equipment architecture, ensuring function realization while considering compactness.

[0043] In order to achieve the desired filtering effect, stainless steel or other metal materials with good corrosion resistance can be used to manufacture the filter screen 11. The filter screen 11 has a multi-layer design with decreasing pore size, so that larger particles are first intercepted by the surface layer and smaller particles are gradually filtered. In addition, auxiliary components such as easy-to-disassemble cleaning interface and blowdown port can be equipped to facilitate regular cleaning and maintenance work to maintain its filtering efficiency. For example, the use of quick coupling design simplifies daily maintenance procedures and supports high-pressure flushing functions to further enhance filtering efficiency and service life in practical applications.

[0044] Referring back Figure 3 In one embodiment, the catchment tank 3 of the dissolved air nanometer oxygenation device used in the watershed management of the present application is equipped with multiple stages of mixers 12. The catchment tank 3 is one of the core components of the dissolved air nanometer oxygenation device, mainly responsible for water purification and enrichment processes. In order to improve water purity and oxygenation efficiency, multiple stages of mixers 12 are configured inside the catchment tank 3. Through mechanical stirring, the settling of suspended particulate matter in water is accelerated, effectively improving water purification quality. Specifically, the multiple stages of mixers 12 include several layers of different types of mixing units arranged in layers along the water flow direction. Each layer of mixing units can independently control the speed and rotation direction, achieving more efficient particle aggregation and sedimentation.

[0045] In addition, the design of each layer of mixing units takes into account various fluid mechanics factors to adapt to the physical properties of different types of particles, ensuring maximum flocculation effect. For example, the uppermost layer of mixing units is designed with larger impeller structures for large-scale dispersion of large particle impurities in water; while the middle layer adopts smaller and densely arranged small paddle designs to finely stir small particles, promoting these particles to collide and combine with each other, and quickly precipitate to the bottom of the catchment tank 3. The lowermost layer of mixing units is responsible for further pushing the formed flocs to the sedimentation zone.

[0046] For example, large, slow-speed, large-area dispersing mixers are installed at the top position near the inlet of the catchment tank 3; high-speed rotating and high-density precision chopping mixers are provided in the middle section; and low-speed powerful pushing mixers are configured near the bottom of the tank. The stages of mixers are supported by a sturdy frame structure and connected by a transmission shaft to an external motor control system, ensuring stable and reliable operation of the entire system.

[0047] In one embodiment, the booster water pump 4 of the dissolved air nanometer oxygenation device used in the watershed management of the present application adopts a centrifugal structure. This structure has the characteristics of high efficiency, stability and high reliability, and is particularly suitable for water quality management occasions that need to be operated for a long time. The booster water pump 4 is equipped with a pressure sensor 13 to realize real-time water pressure monitoring. The sensor is installed at a key position on the pump body to ensure that the collected data is accurate and reliable. The obtained pressure value is fed back to the closed-loop control system through signal transmission, and the system automatically adjusts the working parameters of the booster pump, including but not limited to frequency conversion and power output, to ensure that the entire device is at the set optimal working point. In addition, to ensure that the pressure inside the dissolved air tank remains within the preset range, this automatic adjustment mechanism can dynamically respond to any fluctuations caused by changes in environmental factors, maintaining the stability of the system.

[0048] Specifically, the inlet and outlet of the booster pump 4 are connected to the water inlet pipeline and the dissolved air pressure tank 6 respectively, ensuring the smooth flow of water. At the same time, the pressure sensor 13 is integrated inside the pipeline near the pump cavity and transmits the real-time water pressure information collected to the central control unit in real time. After receiving this information, the closed-loop control system accurately controls the booster pump 4 according to the set threshold. When high or low pressure beyond the range is detected, the controller sends instructions to change the working frequency of the booster pump, so as to adjust the flow rate and pressure to a safe and reasonable range, and keep the system in a balanced state of operation.

[0049] In one embodiment, the dissolved air nano-oxygenation device used in the basin management of the present application is characterized in that a plurality of micro pores 14 are arranged in the high-pressure water pipe 5. Specifically, by arranging a plurality of micro pores 14 in the high-pressure water pipe 5, the water flow entering the dissolved air pressure tank 6 can be dispersed and form a large number of fine droplets. These droplets are further refined under pressure, greatly increasing the contact area between water and air, thereby improving the oxygen dissolution efficiency and increasing the dissolved oxygen concentration in the water flowing out of the system. This design effectively combines water flow pressure and bubble generation technology to enhance the oxygenation effect of the basin water.

[0050] For example, in a specific embodiment, these micro pores 14 are distributed inside the high-pressure water pipe 5 according to a certain rule, ensuring that the water flow sprayed from each pore can be dispersed and intersected to the maximum extent. This layout can be uniformly spaced or designed as an irregular arrangement according to specific needs. The diameter of the micro pores 14 can be adjusted according to different application conditions in order to obtain the best oxygenation effect. At the same time, in order to ensure that the water flow can smoothly pass through these micro pores 14 and maintain the overall stability and high performance of the system, the high-pressure water pipe 5 is made of materials that are resistant to high pressure and have certain corrosion resistance.

[0051] In one embodiment, the dissolved air nano-oxygenation device used in the basin management of the present application is characterized in that a multifunctional drain 15 is arranged at the bottom of the dissolved air pressure tank 6. The multifunctional drain 15 has the dual functions of discharging waste water and cleaning and maintenance, which not only ensures the smooth discharge of waste water, but also provides convenient conditions for regular cleaning and maintenance, ensuring the cleanliness of the internal environment of the dissolved air pressure tank 6. This design effectively prevents the accumulation of sediments and dirt, helps to prolong the service life of the dissolved air pressure tank 6 and its attached structures, and further ensures the stability and reliability of the entire dissolved air nano-oxygenation device. In order to achieve this, the dissolved air pressure tank 6 needs to be reasonably arranged in space to enable the multifunctional drain 15 to be placed at the most advantageous operating position, i.e. the lowest point at the bottom of the tank body, so as to ensure that the water flow or waste liquid is completely discharged and the tank body wall can be easily brushed or flushed.

[0052] For example, in one embodiment, the multifunctional drain 15 of the dissolved air pressure tank 6 adopts a special multi-channel structure. Among them, the main channel is used for the rapid discharge of conventional waste water, and the auxiliary channel is configured with a switch valve to control the liquid flow path during cleaning operation, so that separate cleaning liquid input and waste discharge can be carried out respectively. In addition, flange interfaces are added around the drain to facilitate the installation of hoses or cleaning equipment. Such a design scheme makes the multifunctional drain 15 not only capable of efficiently discharging liquid in the tank, but also simplifies the cleaning and maintenance work process.

[0053] In one embodiment, the dissolved air nano oxygenation device used in the watershed management of the present application is characterized in that the air compressor 7 adopts oil-free compression technology. The air compressor 7 is a key component in the device, responsible for providing high-purity compressed air. The main purpose of using oil-free compression technology is to avoid the mixing of lubricating oil into the compressed air, to ensure the high purity of the supplied compressed air, and thus to ensure the high quality of the dissolved air water. If lubricating oil seeps into the system, it not only increases the impurity content in the air, but also can cause damage or contamination to other components in the system, affecting the overall performance of the equipment and the dissolved air effect.

[0054] For example, the air compressor 7 is installed on one side of the device, facilitating the access of external air and the conversion of air into high-pressure gas through the internal high-efficiency compression mechanism. Such a compressor is usually composed of an air inlet, a piston compression chamber and an air outlet, and all working components are specially designed for lubrication isolation to prevent oil from contacting the compressed air flow. The entire system is tightly connected, and the compressed air generated by the air compressor 7 is directly connected to the dissolved air generator through a pipeline, ensuring the high cleanliness of the air during transmission. Specifically, oil-free compression technology may use special materials such as ceramic piston rings or use advanced coating processes, so that the friction between mechanical moving parts is properly controlled and no lubricating medium is introduced.

[0055] In one embodiment, the air pipe 8 of the dissolved air nano oxygenation device used in the watershed management of the present application is provided with a desiccant layer 16 for removing moisture and impurities in the air. This design can significantly improve the quality of air entering the dissolved air pressure tank 6, thereby ensuring the stability and efficiency of the dissolved air process. Specifically, air often contains a certain amount of moisture and other impurities, and if these impurities are not treated and directly enter the dissolved air pressure tank 6, they may affect its working efficiency and equipment life. Therefore, by setting the desiccant layer 16, the moisture and particulate matter in the air can be effectively removed, ensuring that the air entering the dissolved air pressure tank 6 is in a relatively pure state.

[0056] For example, in one specific embodiment, silica gel or molecular sieve with good hygroscopic properties can be selected as the drying agent and placed at the inlet of the air pipe 8 to ensure that all air entering the air pipe 8 is treated by the drying agent layer 16. In addition, considering the saturation of the drying agent after long-term use, a replaceable or renewable mechanism can be designed on the air pipe 8 to extend the service life of the device. This design not only ensures the high-quality operation of the gas dissolution process but also facilitates later maintenance work.

[0057] The connection between the air pipe 8 and the gas dissolution pressure tank 6 is a sealed interface to prevent the introduction of external impurities during transmission. In this connection, the drying agent layer 16 is located near the air inlet at the front end of the air pipe 8 and is fixed inside by appropriate support materials to prevent it from moving or failing under the action of air flow.

[0058] In one embodiment, as shown in Figure 5 The nanometer oxygen-dissolved water release pipe 9 of the gas-dissolved nanometer oxygen-increasing device used in the basin management of the present application has multiple micro-nano bubble release ports 17 distributed on its pipe wall, allowing the nanometer gas-dissolved water to form tiny bubbles when released, thereby increasing the contact area with the river water and improving the effective diffusion of dissolved oxygen. Specifically, this structural design effectively improves the working efficiency of the gas-dissolved nanometer oxygen-increasing device in the river.

[0059] The nanometer oxygen-dissolved water release pipe 9, as one of the key components of the oxygen-increasing device, can provide more effective gas dissolution supply during river management by optimizing its pipe wall structure and bubble generation method. In traditional methods, the oxygen-increasing efficiency is limited because ordinary oxygen-increasing equipment cannot guarantee sufficient mixing of gas and water and maximize the contact area. By using micro-nano bubble release technology, this device not only improves the transfer rate of gas to the liquid phase but also enhances the overall system operation effect, ensuring that dissolved oxygen can be uniformly distributed in the entire water flow area. This device is suitable for river environments of different scales and conditions and has strong adaptability.

[0060] For example, the nanometer oxygen-dissolved water release pipe 9 can be prepared by high-precision laser drilling or micro-electro-mechanical systems (MEMS) technology, with a large number of tiny openings with diameters ranging from several microns to tens of microns uniformly distributed on its inner wall. These micro-holes not only ensure efficient gas release but also prevent impurities from entering and affecting device performance. For example, the technical solution of a nanoscale ceramic membrane covering can ensure the precision of the tiny openings while extending the service life of the component and maintaining long-term stable gas dissolution capacity.

[0061] In one embodiment, the nanometer oxygen dissolving water release pipe 9 of the dissolved air nanometer oxygenation device used in the basin management of the present application is arranged in a wave shape on the riverbed, with a length of more than 3 times the height of the dissolved air pressure tank 6. This special arrangement can significantly expand the contact range of nanometer dissolved air water and river water, so that oxygen can diffuse in water more uniformly and efficiently. By optimizing the installation position and shape design of the pipeline, the device enhances the effect of dissolved oxygen transmission to the contaminated water body and further improves the efficiency of the water treatment system.

[0062] Specifically, by using the nanometer oxygen dissolving water release pipe 9 in a wave shape, a wider spatial distribution can be occupied on the riverbed surface, ensuring that the released oxygen-rich water can be quickly and fully mixed with river water in a larger range. In order to meet this specific length ratio requirement, the dissolved air pressure tank 6 should be placed at a suitable place on one side of the river and kept stable; at the same time, the nanometer oxygen dissolving water release pipe 9 connected to the outlet end of the pressure tank needs to be laid along the bottom of the river according to the pre-set wave crest and trough. In this process, the release pipe can be bent according to actual needs but must always maintain contact with the riverbed surface.

[0063] For example, in actual deployment, nanometer oxygen dissolving water release pipe 9 made of flexible material with appropriate diameter can be selected to adapt to complex underwater environment and ensure sufficient strength and flexibility. At the same time, in order to facilitate installation and maintenance, a support platform can be established on the shore to place the dissolved air pressure tank 6, and the nanometer oxygen dissolving water release pipe 9 connected to the pressure tank is extended to the riverbed in the predetermined area. By adjusting the working parameters of the pressure tank and the arrangement of the nanometer oxygen dissolving water release pipe 9, the technical requirements of the features can be effectively realized.

[0064] In one embodiment, a temperature controller 18 is provided on the air pipe 8 between the air compressor 7 and the dissolved air pressure tank 6 of the dissolved air nanometer oxygenation device used in the basin management of the present application. This design can effectively adjust the temperature of the input air during the dissolved air process, so that the temperature of the water body is more uniform, thereby optimizing the dissolution conditions and improving the oxygen dissolving effect. The temperature controller 18 is installed at a specific position on the air pipe 8, which can directly monitor and adjust the temperature of the gas transported through the air pipe 8, ensuring that the gas enters the dissolved air pressure tank 6 for treatment at the optimal temperature. This structure not only ensures the accuracy and stability of the operation, but also enhances the reliability and safety of the overall equipment operation. The dissolved air process requires high process precision, especially in terms of temperature control, and small changes in temperature can have a significant impact on the dissolved air efficiency, so the introduction of the temperature controller 18 has important practical significance.

[0065] Specifically, in one embodiment, the temperature controller 18 is composed of multiple sensors and actuators, capable of automatically detecting the gas temperature within the air pipe 8 and quickly adjusting the power output of the heating or cooling elements through the built-in control system. This closed-loop control mechanism ensures that the gas always remains within the set target temperature range. For example, when the sensor detects that the gas temperature in the air pipe 8 is higher or lower than the pre-set threshold, the control system will accordingly increase or decrease the working intensity of the cooling or heating elements to maintain stable operating conditions. In addition, the temperature controller 18 adopts a modular design, facilitating installation, maintenance and debugging, further enhancing the practicality and operability of the equipment.

[0066] In actual operation, when the device is in use, its main purpose is to improve the dissolved oxygen content in river water through the nano-dissolved oxygen technology, thereby improving the ecological environment of the river basin. First, the water pump 1 starts to operate, pumping river water with low oxygen or even no oxygen in the river bottom or a certain area of the river into the system. This not only supplements the dissolved oxygen in the river, but also prepares enough water for the operation of the subsequent equipment.

[0067] Next, the water extracted flows through the lifting pipe 2 to the water collecting tank 3. During this period, the water flow is preliminarily stabilized and impurities may partially settle in the pipe or collection point due to gravity and other factors, ensuring that the water quality is relatively good and free of large impurities, avoiding affecting the subsequent working steps and potential damage to the equipment.

[0068] Then comes the crucial pressurization process: relying on the powerful power of the booster pump 4 to act on the river water flowing out of the water collecting tank 3. After the river water passes through the high-pressure water pipe 5, the pressure is significantly increased to ensure the pressure conditions for subsequent gas dissolution. At the same time, before the gas dissolution link occurs, the air compressor 7 starts and sucks in the surrounding air and compresses it strongly, and the compressed high-pressure air reaches the gas dissolution pressure tank 6 through a separate delivery channel and mixes with the river water after the pressurization treatment. In this cooperative process, because the air is highly compressed and under extremely high pressure, it can be more fully and uniformly dissolved into the water.

[0069] The gas dissolution pressure tank 6 realizes the optimal contact and fusion environment of the two-phase materials of air and water. The air here refers to pure gas that has been purified to remove impurities and can efficiently penetrate into every drop of river water under certain pressure conditions, forming a small liquid droplet or bubble suspension dispersion system containing oxygen at the micro or even nano level. This kind of small water group rich in dissolved oxygen not only has a very high specific surface area, but also can diffuse to a larger water area in a very short time. Such design greatly improves the oxygenation effect. Finally, the nano-dissolved oxygen water flows into the natural river environment from the dedicated nano-dissolved oxygen water release pipe 9.

[0070] Exemplary systems and methods of the present application have been specifically shown and described herein in accordance with the exemplary embodiments, but it will be understood that various changes in the system and / or methods described herein can be made without departing from the spirit and scope of the application, which is defined in the appended claims.
