[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] like Figure 1 and Figure 2 As shown, the ozone micro-nano oxidation water purification device of this application includes a booster pump 2, an intermediate tank 3, a gas-liquid mixing pump 4, a distributor 5, a compressed air preparation system 6, an oxygen preparation system 7, and an ozone generator 8. The entire device aims to achieve in-situ, efficient water purification in rivers through ozone micro-nano technology.

[0031] Specifically, the ozone micro-nano oxidation water purification device comprises several main components: a booster pump 2 for transporting the water to be treated to other units for preliminary preparation; an intermediate tank 3 for storing the pre-purified river water for subsequent steps; a gas-liquid mixing pump 4, which serves as the core processing node and is responsible for mixing appropriate amounts of gas and liquid components; a distributor 5 that can evenly disperse the gas-liquid mixture back into the river; a compressed air preparation system 6 and an oxygen preparation system 7 that create conditions for producing high-purity and high-concentration active agents (specifically ozone) and ensure the necessary prerequisites for its generation; and an ozone generator 8, which is used to produce and provide high-quality ozone.

[0032] Specifically, the booster pump 2 is installed inside the river section requiring treatment to pump water from the river to a treatment facility located on the riverbank. This method allows for the convenient collection of relatively still or slow-flowing wastewater within a specific area and its transport to the next stage of treatment. Furthermore, the booster pump 2 should possess sufficient suction capacity and stability to cope with varying water flow conditions and volume changes.

[0033] Next is the intermediate tank 3, located on the bank as a temporary reservoir. This structure typically has good sealing properties to prevent leakage and a relatively spacious interior to hold a large volume of river water delivered from the booster pump 2. It needs to be made of corrosion-resistant and high-strength materials to ensure it can maintain normal operation even after prolonged exposure to the outdoor environment.

[0034] The gas-liquid mixing pump 4 is connected to the bottom of the intermediate tank 3 and is connected to the outlet port of the storage container and the feed port of the ozone generating unit via pipes. It can extract water containing more sediment and impurities from the bottom of the storage space while simultaneously introducing ozone generated by the preparation system. This design ensures more thorough and complete contact between the gas and liquid, thereby significantly improving the efficiency of the chemical reaction and enhancing the degradation of pollutants.

[0035] In addition, two types of auxiliary preparation subsystems are configured during the operation of the entire equipment: a compressed air preparation system 6 and an oxygen preparation system 7, which are used to prepare ordinary air quality resources or high-purity oxygen sources for use by the ozone-generating terminal equipment, respectively. The effective combination of these two support systems lays a solid foundation for the smooth operation of the ozone generator 8, ensuring a continuous supply of sufficiently potent reaction media for the next stage of disinfection and decontamination treatment.

[0036] The most crucial component, the ozone generator (part 8), must be placed in a dry, well-ventilated area. This device integrates a complex electrical control system and technological processes to process and convert the clean gas feedstock received at the input end into ozone with extremely strong chemical reactivity through a series of transformation steps. Once this step is completed, it provides a powerful driving force for all the aforementioned preparatory work, initiating the most critical stage in the entire water remediation process.

[0037] This equipment utilizes micro- and nano-scale ozone treatment methods and a scientifically designed mechanical layout to achieve on-site, immediate removal of various organic pollutant residues and inhibit excessive bacterial and algal growth. When highly efficient dissolved oxidants (the aforementioned finely distributed, small-particle ozone bubbles) are injected into the polluted water, they quickly produce significant results, restoring the aquatic ecosystem's function and enhancing its self-purification capacity over a large area while maintaining low energy consumption.

[0038] In one embodiment, the intermediate tank 3 of the ozone micro-nano oxidation water purification device of this application is a circular conical-bottom PE tank with a volume of 2 to 5 cubic meters. The design of this PE tank ensures sufficient capacity to hold the water to be treated, and the conical bottom effectively prevents the accumulation of sediment and dirt at the bottom. The circular structure of the tank not only improves space utilization but also makes the liquid flow more uniform and stable. The PE tank is mounted on a steel frame, ensuring the overall structural stability of the equipment. This installation method not only enhances the stability of the equipment but also allows for movement or adjustment as needed.

[0039] Specifically, the steel frame is designed to accommodate the size and weight of the PE drum, ensuring its safe and stable placement. The PE drum and steel frame are connected via fasteners or slots, preventing the drum from shifting or wobbling, further enhancing the equipment's reliability. Furthermore, this assembly allows the PE drum to be removed from the steel frame for regular cleaning and maintenance. For example, in practical applications, when a thorough cleaning or overhaul of the PE drum is required, simply removing the drum from the steel frame is sufficient to complete the operation without disassembling other components.

[0040] Specifically, to ensure the stability of the intermediate tank 3 during operation and to meet design requirements, technicians need to select steel frames of appropriate sizes to match PE tanks of different volumes (2 to 5 cubic meters), and construct the steel frames using materials with strong corrosion resistance and high load-bearing capacity. Furthermore, the PE tanks and steel frames can be securely fixed together using pre-drilled holes and bolts, or by employing a snap-lock mechanism.

[0041] In one embodiment, the gas-liquid mixing pump 4 of the ozone micro-nano oxidation water purification device of this application is a corrosion-resistant pump. This pump is made of special materials, possessing the ability to resist high-concentration ozone corrosion, and can operate stably in ozone-rich environments for extended periods. Specifically, the internal components of the pump are made of materials capable of withstanding strong oxidizing substances, and the overall corrosion resistance of the pump is improved through optimized design and surface treatment. This pump not only effectively draws in ozone gas and fully integrates it with the water flow, but also ensures that the average diameter of the bubbles is at the micro-nano level. This structural design significantly improves the ozone dissolution efficiency in water and the removal efficiency of pollutants.

[0042] In practical applications, to achieve efficient gas-liquid mixing and micro / nano bubble generation, this corrosion-resistant pump is typically installed before or within the main liquid flow path inlet of the device. Its inlet is connected to an ozone source supply system, while its outlet is directly connected to the subsequent water treatment unit. For example, the pump can be tightly integrated with other components via dedicated pipes and connectors, allowing ozone gas to mix uniformly with the water source under high pressure, forming a fine and stable gas-liquid two-phase flow, thereby achieving the desired purification effect.

[0043] In one embodiment, the ozone generator 8 of this application integrates sensors and a controller. Through real-time monitoring and feedback, it precisely regulates the air compressor production system and the oxygen production system 7, enabling collaborative operation among components and ensuring the safety and stability of the ozone generation process. The ozone generator 8 possesses multi-layered protection mechanisms, such as overload protection, temperature monitoring, and emergency shutdown, ensuring normal operation of the equipment under extreme conditions and protecting the safety of operators. Furthermore, the ozone generator 8 can be remotely diagnosed and maintained via network connection, greatly facilitating daily management and troubleshooting.

[0044] Specifically, the ozone generator 8 has a series of system programs that coordinate the control of the air compressor preparation system and the oxygen preparation system 7. For example, when the system detects an increase in the amount of water to be processed, the ozone generator 8 adjusts the ratio of compressed air supply and oxygen concentration according to a preset algorithm to optimize ozone generation efficiency; conversely, it reduces the supply accordingly to save energy and reduce wear. This dynamic adjustment mechanism relies on the precise ratio between the two and the ability to respond to changes in a timely manner. Compressed air and high-purity oxygen are transported to the ozone generation unit through pipeline connections for reaction, thereby achieving the water purification goal.

[0045] In one embodiment, the compressed air preparation system 6 of the ozone micro-nano oxidation water purification device of this application includes an air compressor, a compressed air storage tank, a purifier, and a refrigerated dryer. Specifically, firstly, the air compressor draws in ambient air and pressurizes it to form compressed air, which is then delivered to subsequent equipment. Afterward, the compressed air is stored in the compressed air storage tank, serving to stabilize pressure and buffer, ensuring the continuity and stability of the system. To improve air quality, the purifier processes the stored air, removing any moisture and particulate impurities that may be present. Next, the preliminarily purified air is further cooled by the refrigerated dryer to completely remove any remaining moisture.

[0046] Specifically, in a practical application environment, the aforementioned components are installed in the water purification device according to a specific spatial arrangement: the air compressor is located on one side of the system, responsible for providing the air source; adjacent to it is a vertically placed compressed air storage tank, directly connected to the air compressor outlet via a pipeline to ensure rapid filling of the tank while maintaining system pressure balance; then, the gas pipeline from the storage tank extends to the purifier installed on the same side, which is horizontally placed to maximize the utilization of its effective volume for multi-stage filtration. Finally, after the purification process is completed, the treated gas flows to a refrigerated dryer installed in the same row at an angle to facilitate the smooth discharge of condensate. In this way, a compact and efficient compressed air supply is achieved from the structural layout to the specific operating mechanism.

[0047] For example, a specific model and specification of air compressor can be selected as the starting point, with the air input connected via a standard interface and the flow rate controlled by appropriate valves. The compressed air storage tank is equipped with corresponding safety valves and pressure reducing devices to prevent excessive pressure accumulation. It is connected to other components via seamless steel pipes or other pressure-resistant materials to ensure no leakage risk in the storage process. In addition, the purifier is designed with a high-efficiency activated carbon layer and fiber filter to achieve multi-level interception of pollutants, and an automatic drain valve enables maintenance-free operation of the system. Finally, when configuring the refrigerated dryer, an air-cooled refrigeration method is selected to reduce energy consumption costs, while ensuring that the internal heat exchange tube bundle can dissipate heat efficiently, and continuously deliver the fresh compressed air with extremely low moisture content and purity after being treated for humid heat to the next process node, which is used to generate ozone.

[0048] In one embodiment, the oxygen preparation system 7 of the ozone micro-nano oxidation water purification device of this application includes an air purifier, a desiccant dryer, an oxygen generator, and an oxygen storage tank. The oxygen preparation system 7 is configured to ensure that the oxygen entering the system is pure and meets the required concentration, thereby improving the efficiency of subsequent ozone generation and water treatment processes.

[0049] An air purifier, installed at the front end of the system, removes dust, particulate matter, and other impurities from the air. The clean air from the purifier then enters a desiccant dryer. The dryer removes residual moisture to prevent water vapor from affecting subsequent processing equipment. The dried air is then sent to an oxygen generator. The oxygen generator uses adsorption separation or membrane separation technologies to remove impurities such as nitrogen, extracting high-purity oxygen, which is then delivered to an oxygen storage tank for storage. The oxygen storage tank is installed in a relatively independent location, connected to the preceding equipment, and continuously provides a stable oxygen source to the ozone generator. All components are connected by piping to ensure smooth air and oxygen flow within the system, while also facilitating inspection and maintenance.

[0050] For example, by installing a control valve assembly and sensors, the pressure, humidity, and gas flow rate at each stage can be monitored and adjusted in real time, ensuring the stable operation and safe functioning of the oxygen generation system. Specifically, filtration units and emergency valves are also installed at each key stage to ensure the system's safety and reliability are effectively protected even under abnormal operating conditions.

[0051] In one embodiment, the distributor 5 of the ozone micro-nano oxidation water purification device of this application is a perforated water distribution pipe, mainly used to uniformly distribute ozone bubbles into the water. To achieve optimal gas-liquid mixing, the perforations of the perforated water distribution pipe are designed in two rows arranged at a downward 45° angle. This angle ensures that the ozone bubbles can obtain a large specific surface area when entering the water, which is beneficial for sufficient contact between the gas and liquid phases. A 10 mm orifice diameter is chosen, a size that effectively regulates gas flow rate and dispersion. The spacing between adjacent orifices is set at 100 mm, designed to allow each ozone bubble in the outlet channel sufficient space to rise independently without interfering with each other.

[0052] Furthermore, the specific structural design of distributor 5 also contributes to improving overall efficiency. Distributor 5 injects a gas stream containing a high concentration of ozone into the water through multiple small holes in its pipe wall, allowing the ozone to diffuse rapidly and evenly throughout the entire treatment unit. This arrangement ensures that the gas disperses in an optimized manner as it is injected through these precisely arranged small holes, promoting the efficiency of oxidation reactions in subsequent treatment processes.

[0053] Specifically, in one concrete example, the function of distributor 5 can be achieved by installing the aforementioned perforated water distribution pipe on a horizontal pipeline. Specifically, the perforated water distribution pipe is fixedly installed above the center line of the bottom of the reaction tank in the purified water, maintaining a horizontal orientation, so that the ozone-containing oxygen source from the top can be directly introduced into the water distribution pipe via a connecting pipe. At this time, all the perforations will discharge ozone at a specific angle towards the water flow direction, forming an effective bubble cluster, further ensuring good treatment results.

[0054] In one embodiment, such as Figure 2 and Figure 3 As shown, a removable filter screen 9 is installed at the inlet of the booster pump 2 of the ozone micro-nano oxidation water purification device of this application. This design aims to prevent larger particulate impurities from entering the intermediate tank 3, ensuring the normal operation of subsequent equipment and improving river water treatment efficiency. The filter screen at the front end of the booster pump 2 can filter large suspended solids or sediments, preventing these impurities from entering the system through the water flow, effectively reducing the possibility of blockage and damage. In addition, due to the removable design, maintenance personnel can easily clean or replace it, thereby adapting to the in-situ purification needs under different environmental conditions.

[0055] In one embodiment, a filter screen 9 that can be easily removed and reinstalled can be provided at the inlet of the booster pump 2. This filter screen is made of a robust and corrosion-resistant material with a moderate mesh density, sufficient to block larger solid objects without excessively obstructing water flow. Specifically, one edge of the filter screen is fixed to the outer periphery of the inlet of the booster pump 2, while the other side can be securely closed via a quick-release snap-fit ​​connection, facilitating disassembly and assembly during routine maintenance and repair. For example, when it is necessary to clean the accumulated dirt on the filter screen, it can be quickly removed by simply releasing the snap-fit. After cleaning, it can be easily reinstalled in its original position, ensuring a tight and seamless connection.

[0056] In one embodiment, see Figure 4 The intermediate tank 3 of the ozone micro-nano oxidation water purification device of this application is equipped with a stirrer 10 for uniformly mixing the river water to be treated, thereby improving the contact effect with ozone. The stirrer 10 is installed in the center of the intermediate tank 3, ensuring that the water is sufficiently and uniformly agitated around it, thus allowing ozone to better combine and react with pollutants in the water. This design can effectively promote chemical reactions during the purification process, ensuring that the entire purification process is more efficient and uniform. The stirrer 10 is specifically installed by connecting it to the inner wall of the intermediate tank 3 through a fixed bracket. The fixed bracket is made of high-strength material, capable of withstanding stress and vibration during long-term operation, ensuring the stability of the stirrer 10 during operation.

[0057] The agitator 10 typically consists of a motor-driven shaft and an impeller. Specifically, the motor is mounted on the top of the outer side of the intermediate tank 3 and connected to the shaft via a coupling. The impeller is located at the bottom of the intermediate tank 3 to ensure that the water flows from bottom to top, thereby achieving a better mixing effect. By adjusting the motor speed, the stirring intensity and mixing speed can be flexibly controlled. For example, for different water quality conditions, the system can automatically adjust the speed through a preset program to optimize the treatment effect.

[0058] The inner wall of intermediate tank 3 is smooth, facilitating cleaning and maintenance and reducing the possibility of particulate matter residue in the water. The entire system employs a closed-loop design to prevent the entry of external impurities and the risk of ozone leakage. During operation, wastewater first enters intermediate tank 3, where it undergoes initial contact with a metered amount of ozone and is uniformly mixed by the action of stirrer 10. This configuration not only improves contact efficiency but also reduces the amount of pollutants remaining in subsequent purification processes.

[0059] Return to reference Figure 3 In one embodiment, a flow meter 11 is installed in the pipeline between the gas-liquid mixing pump 4 and the intermediate tank 3 of the ozone micro-nano oxidation water purification device of this application. The flow meter 11 is used to monitor the water flow rate and the mixing ratio of gas and liquid in real time, thereby optimizing the purification effect. Specifically, the flow meter 11 is installed between the gas-liquid mixing pump 4 and the intermediate tank 3. This arrangement ensures that the system can respond instantly to changes in water and gas input and adjust operating parameters as needed. The flow meter 11 itself can employ high-precision sensing technology, possessing excellent stability and repeatability, and is suitable for long-term continuous operation.

[0060] Furthermore, the flow meter 11 not only provides real-time measurement data but also uploads the data to the control system via an integrated data acquisition and communication module. The control system's feedback mechanism can adjust the pump's operating status or regulate the air intake based on this data, ensuring efficient gas-liquid mixing. This results in more stable organic pollutant removal performance, suitable for complex river water treatment scenarios. The flow meter 11 works in conjunction with other components; during monitoring, if any abnormality or deviation from preset values ​​is detected, it can immediately trigger an alarm and prompt maintenance personnel to inspect the system, ensuring the entire device is always operating at its optimal condition.

[0061] For example, an electromagnetic flow meter 11 can be selected as the core component, which has a built-in smart chip and self-diagnostic function. This type of flow meter 11 typically possesses high-pressure resistance and corrosion resistance, and can accurately measure water flow. Meanwhile, the sensor is connected to the controller via a cable to ensure reliable and error-free data transmission. In this way, not only can the water volume and its changing trends be accurately measured, but the gas-liquid mixing ratio can also be effectively controlled to adapt to different wastewater treatment needs.

[0062] In one embodiment, the ozone micro-nano oxidation water purification device of this application is characterized by having multiple nozzles 12 at the outlet of the distributor 5, which are evenly distributed at different depths in the river channel. This design, through multi-point distribution, ensures that the water body is fully oxidized at all levels, thereby enhancing the uniformity and efficiency of water purification. Specifically, the installation position of each nozzle 12 is precisely calculated to ensure a reasonable flow field layout throughout the entire water area, allowing ozone and wastewater to fully contact and react. This distributed arrangement of the nozzles 12 can cover different depths from the bottom of the riverbed to near the water surface, meeting the characteristics and oxidation requirements of water pollutants at different depth levels.

[0063] The connection between the distributor 5 and the nozzle 12 employs a robust and reliable fixed connection structure, such as snap-fit ​​or threaded connections, to ensure stability during long-term use. The nozzle 12 itself is designed as a slender, small-diameter channel to effectively generate micro- and nano-sized bubbles and possesses strong anti-clogging properties. For example, the nozzle 12 can be made of a metal or special engineering plastic with good wear and corrosion resistance, enabling it to maintain stable operation for extended periods under high-pressure water flow and preventing clogging by debris.

[0064] In one embodiment, a pneumatic valve 13 is provided between the compressed air preparation system 6 and the oxygen preparation system 7 of the ozone micro-nano oxidation water purification device of this application. The pneumatic valve 13 is located in the middle of the connecting pipe between the compressed air preparation system 6 and the oxygen preparation system 7, and is fixed in a preset position by fasteners during installation. The pneumatic valve 13 itself consists of three parts: a valve body, an actuator, and a control system. These components are connected by flanges to ensure the airtightness of the airflow channel. The function of this valve is to automatically or manually switch between compressed air and oxygen sources during operation according to different purification requirements, providing the necessary gas source for subsequent ozone generation.

[0065] This layout design makes switching air sources more convenient and allows for flexible adjustment of the type of air entering the device according to actual needs, achieving precise flow control and thus optimizing the generation efficiency of micro-nano bubbles in the water and the overall purification effect. The pneumatic valve 13, as a connection point and regulating mechanism, plays a crucial role in the entire water purification device.

[0066] Specifically, the pneumatic valve 13 changes the airflow path by moving its internal valve core, thereby supplying the ozone generator with air from either the compressed air preparation system 6 or the oxygen preparation system 7 under different operating conditions. For example, during routine maintenance or initial startup, the system can default to using more economical compressed air; while in special water treatment situations, it can quickly switch to a higher purity oxygen supply path to enhance ozone concentration.

[0067] In one embodiment, the ozone generator 8 of the ozone micro-nano oxidation water purification device of this application is equipped with a temperature sensor 14 and a pressure sensor 15. The main function of these sensors is to monitor and control the ozone production environment in real time. By integrating the above sensors, the system can acquire temperature and pressure data in real time during operation and adjust according to preset parameters. Specifically, the temperature sensor 14 is installed near the core components inside the ozone generator 8 to accurately monitor the operating temperature of that area. At the same time, the pressure sensor 15 is arranged in the gas delivery path to detect pressure changes in the airflow channel. After the data from the two sensors are fed back to the control module, the stability and efficiency of the ozone production environment are ensured.

[0068] This monitoring and control system not only improves the efficiency of the ozone generator but also enhances the safety and reliability of water purification. For example, when the temperature or pressure deviates from the preset range, the system automatically adjusts operating parameters or issues a warning to prevent equipment damage or affect the purification effect. Through reasonable sensor deployment and an effective feedback adjustment mechanism, precise control of the entire purification process can be achieved, thereby ensuring stable operation of the device in different environments.

[0069] Specifically, this can be achieved by embedding suitable types of industrial-grade temperature and pressure sensors 15 during the design of the ozone generator 8. The temperature sensor 14 should be selected for its high sensitivity and fast response characteristics and should be fixedly installed around the ozone generating components to ensure measurement accuracy. The pressure sensor 15 should be placed at the main airflow passage and connected to an intelligent control system to dynamically acquire pressure signals and compare them with set values. Based on this analysis, the system parameters can be adjusted in real time to maintain optimal conditions for ozone production.

[0070] refer to Figure 5 In one embodiment, a floating base 16 is provided between the booster pump 2 of the ozone micro-nano oxidation water purification device of this application and the river 1 to be treated, to cope with different river water level heights. The floating base 16 is designed to ensure that the booster pump 2 maintains stable operation and efficiency regardless of whether the water level is high or low. This design expands the application range of the device, making the water purification device suitable for more types of river and lake environments.

[0071] The booster pump 2 is one of the core components of the water purification system, and its performance directly affects the water treatment effect. In traditional fixed installations, changes in riverbed topography and fluctuations in river water level often lead to unstable operation or even failure of the booster pump 2. By introducing a floating base 16, this water purification device can dynamically adjust the pump's position to adapt to different river water levels under different seasons and conditions, thereby maintaining optimal suction and discharge flow channel settings. Furthermore, the presence of the floating base 16 not only increases the stability of the entire system but also improves maintenance convenience and reduces the possibility of failure caused by external factors.

[0072] Specifically, the floating base 16 is typically made of corrosion-resistant materials, such as polymers or specially treated metals, to meet the requirements of prolonged outdoor contact with water. This base is connected to the bank or other robust structures via flexible ropes or chains, ensuring it can rise and fall freely with changes in the river water level and always maintain the lift pump 2 at the appropriate operating height. In some practical applications, an intelligent sensing system can also be equipped to monitor the water level, thereby enabling automated adjustment mechanisms and further enhancing the equipment's intelligence.

[0073] In one embodiment, the bottom of the intermediate tank 3 of the ozone micro-nano oxidation water purification device of this application is provided with an adsorption layer 17 (see [link]). Figure 4 The adsorption layer 17 is used to pretreat some organic pollutants in the water, significantly improving the oxygen solubility in the water and enhancing the subsequent gas-liquid mixing effect, thereby optimizing the in-situ purification efficiency of the river. This structural design not only improves the working efficiency of the device but also ensures the stability of the overall system.

[0074] The adsorption layer 17 is located at the bottom of the intermediate tank 3. Through effective installation, it ensures that the water entering the intermediate tank 3 can first fully contact the adsorption layer 17. This adsorption material has a strong adsorption capacity and can effectively remove some organic pollutants from wastewater, thus providing higher-quality raw water for subsequent treatment steps. The selection and laying method of this adsorption material are important components of the entire device and play a crucial role in the purification effect.

[0075] For example, the adsorption layer 17 is composed of activated carbon or other materials with high adsorption capacity. During installation, the adsorption layer 17 is evenly laid on the bottom of the intermediate tank 3 and secured with a suitable fixing device to prevent loosening or displacement. This design ensures that the water flow can maximize contact with the adsorption material, achieving effective pretreatment. Based on this, the water flow will then smoothly enter the next treatment stage, ensuring efficient and stable gas-liquid mixing.

[0076] In one embodiment, a section of visible pipe 18 (see [reference]) is provided on the pipeline between the gas-liquid mixing pump 4 and the intermediate tank 3 of the ozone micro-nano oxidation water purification device of this application. Figure 2 The visualization tube 18 is installed on a section of pipe between the gas-liquid mixing pump 4 and the intermediate tank 3, allowing operators to observe the gas-liquid mixing effect and operating status in real time. The design of the visualization tube 18 not only provides an intuitive observation window but also facilitates timely adjustments to equipment parameters based on actual conditions to ensure optimal system operation. This structural feature effectively enhances the visualization tube 18 management performance of the entire system, contributing to the precise monitoring and control of key variables in the purification process.

[0077] The gas-liquid mixing pump 4 and the intermediate tank 3 are securely and reliably connected via a connecting flange. The visualization tube 18 is embedded in the pipe section between these two components and is typically made of a highly transparent material such as polycarbonate or plexiglass. These materials offer excellent transparency and chemical resistance, can withstand certain pressures, and maintain stable performance. The visualization tube 18 is connected to the rest of the pipe section using the same sealing and fixing standard components, ensuring that the sealing performance at the interface is not affected. Furthermore, to enhance observation, the visualization tube 18 can be equipped with LED lights or other lighting devices to ensure clear visibility of the internal structure even in low-light operating environments.

[0078] For example, a visualization pipe 18 can be installed at a suitable straight pipe location between the gas-liquid mixing pump 4 and the intermediate tank 3, and a special clamp or bolt can be used to ensure a secure and well-sealed connection. Specifically, the visualization pipe is first accurately installed and leveled, and then sealed and secured with a high-strength sealing washer and fixing nut or flange. Meanwhile, for ease of observation, appropriate markings or scales can be set to visually determine the flow state and bubble density, thereby assisting operators in making necessary adjustments quickly and accurately.

[0079] In one embodiment, the size of the ozone generator 8 in the ozone micro-nano oxidation water purification device of this application does not exceed one-third of the size of the intermediate tank 3. This design helps ensure a compact layout of the overall device and facilitates transportation and installation, thereby significantly saving space resources and improving the overall practicality of the equipment. By limiting the size of the ozone generator 8, the coordination and stability of the various parts of the water purification device are optimized. In addition, the smaller size of the ozone generator 8 can reduce the manufacturing and installation costs of the equipment while ensuring performance. With its compact design, the intermediate tank 3 and the ozone generator 8 can better adapt to different installation environments, especially suitable for applications requiring compact configuration or limited space.

[0080] To meet the aforementioned size requirements, the ozone generator 8 is strategically positioned on one side of the intermediate tank 3 and secured with a rigid bracket. The internal structure of the ozone generator 8 has been optimized, employing a multi-layered integrated design to reduce lateral space occupation. For example, key components such as the power system, control system, and gas generation system can be stacked vertically, effectively reducing the overall width and depth of the unit.

[0081] In one embodiment, the distributor 5 of the ozone micro-nano oxidation water purification device of this application is equipped with multiple sets of adjustable nozzles 19, the orientation and spray angle of which can be flexibly adjusted. Specifically, these nozzles are distributed on the distributor 5, securely mounted below the distributor 5 via connectors, and their orientation and spray angle can be adjusted manually or mechanically. By adjusting the angle of different nozzles, the water purification device can adapt to various river topography and water flow conditions to achieve more precise and efficient oxidation purification operations. The distributor 5 and the nozzles are connected by connecting parts made of corrosion-resistant materials, ensuring the long-term stability of the device in complex river environments.

[0082] In the specific implementation plan, this design allows each nozzle to be independently adjusted for different water treatment needs to achieve the best oxidation effect. For example, in narrow and fast-flowing river sections, some nozzles can be moved downstream and the spray angle appropriately increased; while in areas with wider water surfaces and lower flow velocities, the direction of the nozzles can be adjusted to make the bubbles diffuse more evenly and cover a larger area. In addition, this adjustment method can also be combined with water level changes or seasonal factors to adjust the nozzles in real time, thereby ensuring the high efficiency and continuity of the treatment process.

[0083] In actual operation, when this device is used, the ozone micro-nano oxidation water purification device achieves efficient purification of the water quality in the river to be treated (1) through the coordinated work of its various components. The entire treatment process can be broken down into the following key steps and synergistic mechanisms.

[0084] First, the booster pump 2 is placed in the river channel 1 to be treated, responsible for extracting and transporting the river water to be treated to the intermediate tank 3 set up on the bank. This step is crucial, ensuring that the water to be treated can be successfully transferred from the original environment to a relatively stable, closed environment for treatment.

[0085] Next, after the river water transfer is complete, the gas-liquid mixing pump 4 will play a crucial role. This pump is connected to both the intermediate tank 3, which contains the water to be treated, and the key ozone generator 8. At this point, the ozone generated by the ozone generator 8 will be drawn into the gas-liquid mixing pump 4, while the gas-liquid mixing pump 4 will draw water from the bottom of the intermediate tank 3. The advantage of this is that the lower oxygen content of the water at the bottom makes it easier to mix thoroughly with the ozone. The combination of the two can effectively create a mixture of liquid and high-concentration micro-nano-sized bubbles. These finely distributed bubbles in the water flow can greatly improve the efficiency of subsequent reactions and ensure sufficient contact time to degrade pollutants.

[0086] The resulting ozone-rich micro-nano bubbles, mixed evenly with the wastewater, are then pumped back into the river via a special component distributor 5. This step is crucial for returning the pre-treated clean water to nature and, through natural flow or specific design, allows the clean water to cover as wide an area as possible to maximize the impact of the purification process.

[0087] Meanwhile, to ensure a continuous supply of ozone, the system in this application is also equipped with a compressed air preparation system 6 and an oxygen preparation system 7 as gas source support. The compressed air preparation system 6 can easily collect ambient air, process it, and convert it into one of the raw materials suitable for ozone production; the oxygen preparation system 7 is specifically used to improve the gas purity to a higher standard before supplying it to the ozone generator 8. These two systems can adjust the gas supply mode according to specific application needs (such as prioritizing the use of more efficient, high-purity oxygen), thereby meeting the output requirements of different application scenarios and ensuring long-term stable operation.

[0088] Overall, the ozone micro-nano oxidation water purification device has achieved the goal of water body restoration through the carefully designed series of processes described above.

[0089] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this application.
