[0024] Micro-nano bubble technology has shown broad application potential in gas-liquid mixing applications due to its stability and tiny size. Especially in the field of ozone-containing micro-nano bubble water, its ozone solubility significantly exceeds the conventional saturation concentration, and ozone, as a strong oxidant, has a redox potential of 2.07 volts. The combination of microbubble (MB) and ultrafine bubble (UFB) technology with ozone oxidation significantly improves the solubility and oxidation capacity of ozone. This innovative and effective method has been used in applications such as advanced treatment of difficult-to-degrade wastewater, cleaning processes in the semiconductor industry, and general cleaning tasks. Ozone concentration is a key parameter in these applications because it determines the effectiveness of ozone MB and UFB generation equipment and the efficiency of the cleaning process. Ozone concentration must be accurately measured to evaluate the performance of different ozone generation systems and to ensure the effectiveness of ozone-enriched water products used in the above applications.

[0025] The study found that membrane polarography has significant limitations in determining ozone concentration in water containing MB and UFB. Since ozone in bubbles attached to the electrode surface can penetrate the membrane and enter the electrolyte, the measured ozone concentration will exceed the actual concentration in the water. As the bubble density increases, the deviation of the measurement results will also increase because the affected surface area increases with the number of bubbles. In addition, the flow rate of the fluid flowing over the electrode surface is another critical factor; an inappropriate flow rate may not effectively remove the attached bubbles, further affecting the measurement accuracy. High concentrations of ozone may also corrode the membrane used in the measurement, affecting its performance and making the results unstable. In order to ensure the accuracy and reliability of ozone concentration determination, membrane polarography requires specific adaptation measures, such as maintaining a flow cell with an appropriate flow rate and regularly checking and replacing damaged membranes. Although this method can be used to measure ozone concentration in bubble-free water in the range of 0-20ppm, it is not applicable for concentrations exceeding 20ppm.

[0026] Likewise, UV photometry has limitations in accurately determining ozone concentrations in water containing MB or UFB. MB and UFB scatter and reflect UV light, exaggerating the associated absorption measurements. With high bubble densities, significant scattering occurs, so the number and size of the bubbles further influence the measurements. Additionally, the dynamics of bubbles in water, such as formation, floating, and bursting, can cause fluctuations in the absorption readings, complicating the measurement process.

[0027] Although the ozone concentration obtained by iodine titration in water containing MBs and UFBs is not directly significantly affected, the dissolved ozone concentration in the water may change when the ozone molecules inside the bubbles transition to a dissolved state. Therefore, in order to accurately determine ozone levels in these complex environments, existing measurement methods need to be adapted and specific considerations need to be made to ensure the accuracy and reliability of the measurements.

[0028] In the field of ozone concentration monitoring, UV spectrophotometry and iodine titration each have unique advantages, but also have significant limitations, especially in water environments containing microbubbles (MB) and ultrafine bubbles (UFB). In order to comprehensively evaluate the applicability and limitations of these two methods, we have compiled the measurement results of the two methods into the following table (Table 1) to show the measurement deviation and stability of the two methods under different conditions.

[0029] Table 1: Deviation and stability of ozone concentration measurement in water containing MB and UFB by UV spectrophotometry and iodine titration

[0030] It can be clearly seen from Table 1 that the measurement deviation and stability of UV spectrophotometry under bubble-free conditions are good, with an average deviation of only 2.1%, a standard deviation of 0.5%, and a stability of 98.7%. However, with the introduction of microbubbles (MB) and ultrafine bubbles (UFB) in water, the measurement deviation of UV spectrophotometry increased significantly, reaching 5.3% and 8.7%, respectively, and the standard deviation also increased to 1.2% and 2.1%, while the stability decreased to 95.4% and 92.3%, respectively. This shows that the scattering and reflection effects of bubbles have a significant impact on the measurement results of UV spectrophotometry, resulting in increased measurement deviation and fluctuation.

[0031] In contrast, the measurement deviation and stability of the iodine titration method under bubble-free conditions were also excellent, with an average deviation of 1.5%, a standard deviation of 0.4%, and a stability of 99.2%. Even in water containing MB and UFB, the measurement deviation and stability of the iodine titration method only increased slightly, to 1.8% and 2.3%, respectively, with standard deviations of 0.5% and 0.6%, and stabilities of 98.9% and 98.5%, respectively. This shows that the iodine titration method has good stability in an environment with bubbles, but the stability of its measurement results may still be affected in an environment with dynamic changes in bubbles.

[0032] UV spectrophotometry and iodine titration have their own limitations in water containing MB and UFB. Under the influence of bubble scattering and reflection effects, the measurement deviation and fluctuation of UV spectrophotometry increase significantly, while iodine titration is relatively stable in the presence of bubbles, but the stability of the measurement results still needs to be further improved in the environment of dynamic changes of bubbles.

[0033] In view of the advantages and disadvantages of the above methods, UV spectrophotometry has significant advantages in continuous monitoring of ozone concentration, while iodine titration performs well in single-point determination. Therefore, the results of iodine titration are used to calibrate the measurement of UV spectrophotometry in water containing MB or UFB. Through this calibration and control measure, the reliability and accuracy of UV spectrophotometry in continuous monitoring of ozone concentration in solutions containing micro-nano bubbles can be significantly improved.

[0034] Based on this, the present application provides a new detection device, which aims to accurately measure the ozone concentration in a micro-nano bubble solution containing ozone, while having the advantages of easy operation and real-time monitoring, filling the gaps in the prior art, promoting the application of micro-nano bubble technology in a wider range of fields, and ensuring the efficiency and safety of operation.

[0035] See also Figure 1 , Figure 11 is a schematic diagram of the structure of the ozone content detection device in the solution in the embodiment of the present application. The present application provides an ozone content detection device in the solution, which includes a sample chamber 10, a detection unit 20 and a processor 30; the sample chamber 10 includes a receiving cavity 101 for receiving the test liquid, the receiving cavity is provided with a liquid inlet 102 and a liquid outlet 103, and the sample chamber 10 also includes a plurality of optical path isolation devices ( Figure 1 The optical path isolation device is used to reduce the emission deviation of ultraviolet rays; the detection unit 20 includes an ultraviolet emitter 201 and a detector 202, the wavelength window of the ultraviolet emitter 201 is set to match the specific absorption peak of ozone molecules; the detector 202 includes an ultraviolet light sensor, and the ultraviolet light sensor includes a drift correction module ( Figure 1 Not shown), the drift correction module is used to correct the detection error caused by external ambient light; the processor 30 is used to receive the initial concentration transmitted by the detection unit 20, and the processor 30 has a built-in concentration correction module. The concentration correction module uses correction parameters to correct the initial concentration to obtain the ozone content concentration. The correction parameters are obtained by combining ultraviolet spectrophotometry and iodine titration.

[0036] Among them, the detection equipment includes a detection unit, which obtains the initial concentration of ozone content based on ultraviolet spectrophotometry; at the same time, the detection equipment also includes a concentration correction module, which combines iodine titration with ultraviolet spectrophotometry, calculates the correction coefficient through the difference between the two concentrations, and then uses the correction coefficient to correct the initial detection concentration, so that the detection result is more accurate.

[0037] In one embodiment, ozone concentration is measured using iodine titration and ultraviolet light. The ozone concentration determined by ultraviolet light and iodine titration is plotted on the x-axis and y-axis of the graph, respectively, and the result is linearly fitted. The fitting curve is represented by y = kx + b. Several samples are randomly selected during the continuous ultraviolet detection process for iodine titration test. The adjusted ultraviolet measurement value is associated with the result of iodine titration by linear regression analysis. The ozone content in water can be continuously measured.

[0038] Among them, linear regression is actually to link two variables through a linear equation. One variable is the independent variable in the equation, also called the predictor variable; the other variable is the dependent variable in the equation, also called the response variable. In this method, the concentration measured by ultraviolet spectrophotometry is used as the predictor variable, and the concentration measured by iodine titration is used as the response variable, and the correction parameter is calculated by the difference between the two concentrations. That is, when using ultraviolet spectrophotometry to detect the ozone content in the solution, the iodine titration method is used to correct it, and y=kx+b can be obtained, which is used to correct the ozone concentration result measured by ultraviolet spectrophotometry.

[0039] The ozone content detection device provided in the present application can obtain a new correction coefficient each time before testing the test solution, or can update the correction coefficient periodically. The concentration correction module can pre-store correction coefficients for multiple different scenarios to adapt to different test liquids and make the correction result more accurate.

[0040] In one embodiment, the processor 30 is also used to obtain the application scenario of the test solution, and select the correction parameters that match the application scenario to correct the initial concentration. Among them, each time an application scenario is changed, the correction parameters may be different. For example, if the volume of the reaction tank is changed, the correction parameters will change. Therefore, it is necessary to update the correction parameters according to the application environment. In other words, it can be judged before correction whether the application environment obtained by the correction parameters is consistent with the application environment of the current test. If they are consistent, the correction parameters are directly obtained for correction. If they are different, the correction parameters are updated according to the current application environment. The application scenario can be identified by obtaining the application environment parameters. The application environment parameters can be parameters that can reflect the application environment, such as the volume of the reaction tank, and the optimal correction parameters under the background of the solution are selected or updated to generate a correction value consistent with the background.

[0041] In one embodiment, the device also includes a built-in or external bubble particle analysis module, which is used to obtain auxiliary parameters of the test solution, and the auxiliary parameters include one or more of the number of micro-nano bubbles, the size distribution of micro-nano bubbles, and the concentration of micro-nano bubbles. The auxiliary parameters are used to determine the application scenario mode.

[0042] In one embodiment, the processor further includes a correction equation for selecting a correction equation matching the application scenario to measure the ozone concentration of the application scenario according to the application scenario of the test liquid or user customization.

[0043] In one embodiment, the concentration correction module is also used to determine whether the correlation parameter R square value is greater than a preset value, and the preset value range is 0.5-1.0; in response to the correlation parameter R square value being greater than the preset value, the initial concentration is corrected using the current correction parameters; in response to the correlation parameter R square value being less than or equal to the preset value, the correction parameters are updated, and the initial concentration is corrected using the updated correction parameters.

[0044] Please continue reading Figure 2 , Figure 2 1 is a schematic diagram of the structure of an ozone content detection device in a solution in an embodiment of the present application. The present application provides an ozone content detection device in a solution, the detection device comprising a sample chamber 10 , a detection unit 20 and a processor 30 .

[0045] The sample chamber 10 includes a holding cavity 101 for holding the test liquid. The holding cavity 101 is provided with a liquid inlet 102 and a liquid outlet 103. The liquid inlet 102 and the liquid outlet 103 are designed to minimize light scattering and absorption errors caused by micro-nano bubbles.

[0046] Furthermore, the sample chamber 10 further includes a plurality of optical path isolation devices (not shown) to prevent the deviation of the ultraviolet emission effect caused by liquid disturbance or non-uniformity.

[0047] In one embodiment, the sample chamber 10 further includes a filter 104, which includes a porous structure and is used to filter the test solution to remove large-diameter bubbles and suspended solids. Specifically, the sample chamber is optimized with a built-in filter, which has a porous structure and can effectively remove large-diameter bubbles and suspended solids, thereby ensuring that the bubbles in the test solution are evenly distributed and without interference, and achieving high-precision ozone detection.

[0048] Optionally, the porous structure can be a multi-layer micro-mesh structure, a porous membrane material, a dissolution diffusion material, or the like.

[0049] In one embodiment, the detection unit 20 includes an ultraviolet emitter and a detector. The wavelength window of the ultraviolet emitter is precisely set at 253.7 nm ± 0.3 nm to match the specific absorption peak of ozone molecules; further, the ultraviolet emitter includes a multilayer interference filter to further enhance the directionality and purity of the 253-254 nm ultraviolet light beam and reduce the interference of other wavelengths on the measurement process. The detector uses a high-sensitivity ultraviolet sensor that can capture the smallest absorbance changes within the spectral response range, and continuously tracks the influence of external ambient light through a built-in real-time drift correction module, compensating for output signal drift caused by factors such as temperature drift, light source aging, environmental changes, and mechanical vibrations, to ensure the accuracy and stability of the sensor output signal. Through real-time monitoring and dynamic correction, the drift correction module can effectively improve the performance and reliability of the ultraviolet sensor to ensure the accuracy of the measurement.

[0050] In one embodiment, the test solution contains micro-nano bubbles, the diameter of which is greater than or equal to 1 nanometer and less than 200 microns. The presence of micro-nano bubbles can cause scattering and reflection of ultraviolet rays, thereby affecting the accurate measurement of absorbance. This scattering can cause the absorbance reading to be high, resulting in inaccurate ozone concentration measured. The number and size of the bubbles are also key factors, because the density of the micro-nano bubbles is different, resulting in different scattering effects, further affecting the measurement results. In addition, the dynamic changes of bubbles in water, such as formation, floating and rupture, can cause fluctuations in absorbance readings, increasing the complexity of the measurement process.
