Description

Technical Field

[0001] This invention relates to the technical field of drinking water treatment, and specifically to a water treatment system and method with micro-nano bubble generation technology. Background Technology

[0002] With the increasing scarcity of water resources and the aggravation of water pollution, water treatment technology has become an important research area for global environmental protection and resource utilization. Traditional water treatment methods, such as physical filtration, chemical reactions, and ultraviolet sterilization, are widely used, but they still have certain limitations in terms of treatment efficiency, energy consumption, operational complexity, and cost control. Furthermore, as people's requirements for drinking water increase, traditional methods of water treatment related to drinking water often require additional chemicals and energy-intensive equipment, leading to unstable treatment results and placing a burden on the environment.

[0003] Many water treatment systems have been developed. Through extensive research and reference, we found existing water treatment systems disclosed in publications such as CN118666379A, CN117023768A, CN117699961A, CN107983185A, EP1966093A1, US20080073258A1, and JP2021159859A. These systems generally include a water purification terminal, a control terminal, and a water delivery terminal. The control terminal controls the coordinated operation of the water delivery terminal and the water purification terminal. The water delivery terminal transports the water to be treated, allowing it to flow through the water purification terminal. The water purification terminal purifies the water. However, because the purification process in these systems is relatively simple, lacking optimization and improvement of drinking taste, the purified water quality and the drinking water's taste deteriorate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned water treatment systems by proposing a water treatment system and method incorporating micro-nano bubble generation technology.

[0005] The present invention adopts the following technical solution:

The water tank terminal provides space for the water treatment process. The bubble generation terminal generates micro / nano bubbles during the water treatment process.

The water quality monitoring terminal monitors the water quality parameters of the treated water and generates water quality monitoring information. The central control terminal controls the coordinated operation of the water tank terminal, bubble generation terminal, water flow regulation terminal, and water quality monitoring terminal.

[0013] A water treatment method incorporating micro / nano bubble generation technology is applied to a water treatment system as described above, wherein the water treatment method incorporating micro / nano bubble generation technology includes:

[0014] S1 generates micro-nano bubbles during water treatment;

[0015] S2, the water to be treated is transported and interacts with air bubbles, and the water flow rate and volume are adjusted during the treatment process;

[0016] S3 monitors the water quality parameters of the treated water and generates water quality monitoring information;

[0017] S4 controls the coordinated operation of various terminals in the control system.

[0018] The beneficial effects achieved by this invention are:

[0019] 1. By configuring a bubble generation terminal, including a bubble generation module, a bubble control module, and a bubble distribution module, micro-nano-scale bubbles can be precisely generated during water treatment. The bubble control module adjusts the bubble size and generation frequency, and the bubble distribution module evenly distributes the bubbles into the water, thereby increasing the contact area and dissolution efficiency of the bubbles in the water. This is beneficial for increasing dissolved oxygen concentration and promoting rapid water quality improvement during water treatment, thus achieving multiple optimization treatments for the water: purifying the water by breaking down impurities; improving the digestibility and absorption of beneficial substances in the water by ionizing them; and improving the drinking taste while reducing the size of large molecular clusters in the water by reducing their size.

[0020] 2. By setting up the water flow regulation terminal, including the flow rate regulation module, the flow velocity regulation module, and the flow direction control module, the flow rate and velocity of the water to be treated can be precisely adjusted. At the same time, the flow direction of the water can be controlled to maintain an appropriate relative position with the direction of bubble generation, thereby ensuring effective contact between the bubbles and the water and improving the treatment efficiency. This is conducive to optimizing the transfer of bubbles and increasing the dissolved oxygen in the water, ultimately improving the effect and efficiency of water treatment.

[0021] 3. By setting up a water quality monitoring terminal, including a dissolved oxygen monitoring module, a water quality parameter monitoring module, and a water quality monitoring information generation module, it is possible to monitor important water quality parameters such as dissolved oxygen concentration, pH value, temperature, and turbidity in the water in real time, and then generate water quality monitoring information to reflect changes in water quality in real time. This is beneficial for adjusting various parameters in the water treatment process in real time, ensuring that the water quality is always kept in the best treatment state, and improving the drinking taste.

[0022] 4. Through the central control terminal, which includes a data processing module, a control decision module, and a collaborative adjustment module, the system can analyze water quality change trends based on real-time water quality data provided by the water quality monitoring information generation module. Based on the analysis results, it can formulate optimized control decisions and adjust the working status of the bubble generation terminal and the water flow adjustment terminal to ensure the coordinated operation of each module. This facilitates efficient and automated control of the water treatment process and improves the overall processing capacity and stability of the system.

[0023] 5. Through the settings of the bubble control module, including the bubble generation frequency calculation submodule, the bubble control submodule, and the adjustment execution submodule, the optimized bubble generation frequency can be calculated based on water quality parameters and water quality monitoring information. Under the action of the bubble control submodule, the generation frequency and size of the bubbles are adjusted to ensure that the generated bubble frequency matches the water treatment requirements, thereby optimizing the distribution and efficiency of the bubbles, improving the bubble utilization rate in the water treatment process, and thus helping to improve the water treatment effect and energy efficiency.

[0024] 6. By setting up a water quality monitoring information generation module, including a water quality monitoring information generation submodule and a bubble stability assessment submodule, water quality monitoring information and bubble stability assessment information can be generated based on real-time monitoring of water quality parameters. Then, based on these data, the stability of bubbles can be dynamically assessed, which is conducive to early detection of bubble instability and adjustment, ensuring the stability of bubbles in the water treatment process, thereby improving the water treatment effect and ensuring the continuous effect of bubbles in the treatment process.

[0025] 7. By assessing the stability of bubble generation, the system can precisely control the frequency and size of bubble generation based on changes in multiple factors such as water flow velocity, bubble diameter, dissolved oxygen concentration, and temperature, achieving periodic changes over time. This function enables precise control of bubble generation during water treatment, ensuring that the generation frequency matches water quality requirements. This, in turn, increases the contact area between micro / nano bubbles and water, enhances bubble dissolution efficiency, effectively accelerates dissolved oxygen release and water quality improvement, thereby optimizing water treatment results and adapting to different water quality conditions, thus improving the system's adaptability and stability.

[0026] 8. By adjusting the bubble generation frequency in relation to water flow rate, temperature, and dissolved substance concentration, the system can dynamically adjust the bubble generation frequency based on changes in parameters such as water flow rate, bubble input diameter, temperature, and dissolved substance concentration. This adjustment method enables precise matching of bubble generation frequency during water treatment, optimizing the interaction between water flow and bubbles. Furthermore, the effects of temperature and dissolved substance concentration are considered in real time, thereby improving water treatment efficiency. Especially under different environmental and water quality conditions, the system can dynamically adjust the bubble generation frequency based on real-time feedback to ensure optimal water treatment results, thus improving water purification and reducing treatment time.

[0044] Combination Figure 3 As shown, Figure 3 The following is a statistical chart showing the calculation results of bubble generation frequency. To better understand the calculation process, an example of bubble generation frequency calculation is provided below:

[0045] Given: Q = 2.0m 3 / s, V=10.0m 3 P input =100W, d input =50μm, T=30℃, C=12mg / L, T0=25℃, C0=10mg / L, α1=0.05, β=0.3, γ=0.2, α2=0.01, t=1200s. The calculation process is as follows:

[0046]

[0047] Since the frequency requirement in industrial water treatment scenarios is between 100Hz and 5000Hz, the bubble generation frequency calculated by the calculation example is qualified and usable, so the system can realize the function of adaptively adjusting the bubble generation frequency.

[0048] The following is the program code for calculating the bubble generation frequency:

[0049]

[0052] In summary, the aforementioned system and algorithm, through the bubble generation terminal including a bubble generation module, a bubble control module, and a bubble distribution module, can precisely generate micro-nano-scale bubbles during water treatment. The bubble control module adjusts the bubble size and generation frequency, and the bubble distribution module evenly distributes the bubbles into the water, thereby increasing the contact area and dissolution efficiency of the bubbles. Through the water flow regulation terminal including a flow rate regulation module, a flow velocity regulation module, and a flow direction control module, the flow rate and velocity of the water to be treated can be precisely adjusted, while controlling the flow direction to maintain an appropriate relative position with the bubble generation direction, thus ensuring effective contact between the bubbles and the water and improving treatment efficiency.

When S(t) < S ref When S(t) ≥ S refWhen the bubble stability reaches the target, the bubble stability assessment submodule generates bubble stability assessment information to indicate that the bubble stability meets the target. ref This represents the bubble stability assessment threshold, set by the administrator based on experience.

Implementing this function enables precise control of bubble generation during water treatment, ensuring that the generation frequency matches water quality requirements.
