Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a water quality desalination detection device and method for water environment monitoring. Background Technology

[0002] In water environment monitoring, accurate detection of metal elements in water bodies is crucial. However, natural water bodies or industrial wastewater often contain high concentrations of salt. When these salts are detected using equipment such as inductively coupled plasma mass spectrometry (ICP-MS), they cause severe matrix interference and may lead to problems such as instrument cone blockage and signal suppression, affecting the accuracy of detection and the stability of the instrument. Current technologies typically employ offline pretreatment methods to desalinate water samples, but this method is cumbersome, time-consuming, and prone to human error or sample contamination, failing to meet the high-throughput, high-precision, and automated requirements of modern environmental monitoring. Therefore, there is an urgent need for an integrated device capable of online, automated desalination pretreatment and integrated with detection instruments. Summary of the Invention

[0008] The desalination module includes an ultrapure water tank and an elution solution tank. The ultrapure water tank is connected to the inlet of the metal enrichment column via a third water pump, and the outlet of the metal enrichment column is connected to a waste liquid tank. The elution solution tank is connected to the inlet of the metal enrichment column via a fourth water pump.

[0009] The detection module includes an inductively coupled plasma mass spectrometer (ICP-MS), the inlet of which is connected to the outlet of the metal enrichment column via a fifth water pump.

[0010] A control module is connected to the capture module, enrichment module, sample injection module, desalination module, and detection module respectively. The control module is used to control the water pumps in the capture module, enrichment module, sample injection module, desalination module, and detection module to achieve water quality desalination detection.

[0011] The control module includes a data acquisition unit, a processing unit, and a control unit. The data acquisition unit is used to acquire the operating parameters of each module. The processing unit is used to analyze and process the operating parameters to determine whether each module is operating normally. If an abnormality is determined, the adjustment parameters of the module are set according to the operating parameters. The control unit is used to set the initial parameters of each module and control each module according to the adjustment parameters.

[0012] Preferably, the operating parameters collected by the acquisition unit for each module include: the real-time flow rate and real-time pressure of the first, second, third, fourth, and fifth water pumps; and the real-time temperature, real-time pressure, and outlet conductivity of the metal capture column and the metal enrichment column.

[0014] Each water pump has a preset flow rate and preset pressure.

[0015] The real-time flow rate of each water pump is compared with the corresponding preset flow rate, and the real-time pressure of each water pump is compared with the corresponding preset pressure.

[0016] If the real-time flow rate of each water pump is within the preset flow rate range and the real-time pressure of each water pump is within the preset pressure range, then the corresponding water pump is judged to be operating normally.

[0017] Otherwise, the corresponding water pump is judged to be operating abnormally, and adjustment parameters are set according to the flow rate difference between the real-time flow rate and the preset flow rate of each water pump and the pressure difference between the real-time pressure and the preset pressure of each water pump.

[0018] Preferably, the processing unit analyzes and processes the operating parameters to determine whether each module is operating normally, including:

[0019] The operating parameters include the real-time capture temperature, real-time capture pressure, and capture conductivity at the outlet of the metal capture column;

[0020] Obtain the adsorption material of the metal trapping column, and determine the preset trapping temperature of the metal trapping column based on the adsorption material;

[0021] A first acceptable temperature range is determined based on the preset capture temperature. If the real-time capture temperature is within the first acceptable temperature range, the preliminary determination that the metal capture column is operating normally is confirmed.

[0022] A preset capture pressure is set, and a first acceptable pressure range is determined based on the preset capture pressure. If the real-time capture pressure is within the first acceptable pressure range, the secondary judgment of the metal capture column is determined to be operating normally.

[0024] Otherwise, the metal capture column is deemed to be malfunctioning.

[0025] Preferably, determining whether the reaction is normal based on the capture conductivity at the outlet includes:

[0027] The changes in the captured conductivity are compared to determine the minimum value of the captured conductivity change, and the time corresponding to the minimum value is obtained.

[0028] If the time corresponding to the minimum value is a time before the specified time, the reaction is judged to be normal;

[0029] If the time corresponding to the minimum value is the specified time, then the reaction is judged to be abnormal.

[0030] Preferably, if the processing unit determines that there is an operational abnormality, it adjusts the parameters of the operation parameter setting module according to the following:

[0031] The temperature adjustment amount is determined based on the temperature difference between the real-time capture temperature of the metal capture column and the preset capture temperature;

[0032] The capture pressure adjustment amount is determined based on the capture pressure difference between the real-time capture pressure of the metal capture column and the preset capture pressure;

[0033] If the reaction is determined to be abnormal, the adsorbent material of the metal capture column shall be replaced or replenished.

[0034] Preferably, the processing unit analyzes and processes the operating parameters to determine whether each module is operating normally. If an abnormality is determined, the unit sets adjustment parameters for the module based on the operating parameters, including:

[0035] The operating parameters include the real-time enrichment temperature, real-time enrichment pressure, and enrichment conductivity at the outlet of the metal enrichment column.

[0036] Obtain the enrichment material for the metal enrichment column, and determine the preset enrichment temperature of the metal enrichment column based on the enrichment material;

[0037] A second acceptable temperature range is determined based on the preset enrichment temperature. If the real-time enrichment temperature is within the second acceptable temperature range, the preliminary judgment that the metal enrichment column is operating normally is determined.

[0038] A preset enrichment pressure is set, and a second acceptable pressure range is determined based on the preset enrichment pressure. If the real-time enrichment pressure is within the second acceptable pressure range, the secondary judgment of the metal enrichment column is determined to be operating normally.

[0039] The reaction is determined based on the enrichment conductivity at the outlet. If the reaction is determined to be normal, the metal enrichment column is finally determined to be operating normally.

[0040] Otherwise, the metal enrichment column is deemed to be operating abnormally, and the temperature adjustment amount is determined based on the temperature difference between the real-time enrichment temperature and the preset enrichment temperature; the enrichment pressure adjustment amount is determined based on the enrichment pressure difference between the real-time enrichment pressure and the preset enrichment pressure; the adsorption material of the metal enrichment column is replaced or replenished.

[0041] Preferably, determining whether the reaction is normal based on the enriched conductivity at the outlet includes:

[0042] The enriched conductivity at the outlet is divided into time intervals to determine the change in enriched conductivity at the outlet between adjacent time points.

[0043] The changes in enriched conductivity are compared to determine the maximum value of the changes in enriched conductivity, and the time corresponding to the maximum value is obtained.

[0044] If the time corresponding to the maximum value is a time before the specified time, the reaction is judged to be normal;

[0045] If the time corresponding to the maximum value is the specified time, then the reaction is judged to be abnormal.

[0046] Preferably, the control unit is used to set the initial parameters of each module, including:

[0047] Obtain the type and concentration of the capture solution, the adsorption material of the metal capture column, the enrichment material of the metal enrichment column, and the type and concentration of the elution solution;

[0048] The initial parameters for each module are set according to the type and concentration of the capture solution, the adsorption material of the metal capture column, the enrichment material of the metal enrichment column, and the type and concentration of the elution solution.

[0053] Compared with existing technologies, the advantages of this invention lie in its integrated design of a capture module, enrichment module, sample introduction module, desalination module, and detection module, combined with an intelligent control module. This achieves full automation of the entire process of online automatic desalination of water samples, enrichment of target metal elements, and ICP-MS detection, significantly improving detection efficiency and accuracy while reducing human error and sample contamination risks. The control module of this invention can monitor the operating status of each key component (such as flow rate, pressure, temperature, and conductivity) in real time and perform intelligent diagnosis and parameter adjustment through the analysis and processing unit, ensuring the entire device operates in optimal condition and improving its stability and reliability. Through time-series analysis of the outlet conductivity of the metal capture column and metal enrichment column, it can intelligently determine whether the adsorption / enrichment reaction is completed normally and promptly prompt for replacement or replenishment when materials fail or reactions are abnormal, ensuring desalination and enrichment effects. This invention can flexibly adjust initial parameters (such as solution type, concentration, flow rate, etc.) according to different sample matrices and detection requirements, exhibiting good versatility and adaptability.

[0057] like Figure 1 As shown, the present invention provides a water quality desalination detection device for water environment monitoring, comprising:

[0058] The capture module includes a metal capture column and a capture solution tank, wherein the inlet of the metal capture column is connected to the capture solution tank via a first water pump;

[0059] The enrichment module includes a metal enrichment column, wherein the inlet of the metal enrichment column is connected to the outlet of the metal capture column via a second water pump;

[0061] The desalination module includes an ultrapure water tank and an elution solution tank.

[0064] The control module includes a data acquisition unit, a processing unit, and a control unit. The data acquisition unit is used to acquire the operating parameters of each module. The processing unit is used to analyze and process the operating parameters to determine whether each module is operating normally. If an abnormality is determined, the adjustment parameters of the module are set according to the operating parameters. The control unit is used to set the initial parameters of each module and control each module according to the adjustment parameters.

[0065] The water quality desalination detection device for water environment monitoring in this embodiment mainly includes a capture module, an enrichment module, a sample injection module, a desalination module, a detection module, and a control module.

[0066] The capture module includes a metal capture column and a capture solution tank. The metal capture column is filled with a specific adsorbent material. The capture solution tank is used to store conditioning solutions that may be needed during the capture process. The inlet of the metal capture column is connected to the capture solution tank via a first water pump.

[0067] The enrichment module includes a metal enrichment column. The metal enrichment column is filled with an enrichment material (such as a chelating resin) that exhibits high selectivity for the target metal element. The inlet of the metal enrichment column is connected to the outlet of the metal capture column via a second water pump, used to receive the pre-treated water sample and selectively adsorb and enrich the target metal element.

[0068] The sample introduction module includes an autosampler with multiple sample vials for holding the water samples to be tested. The outlet of the autosampler is connected to the inlet of the metal enrichment column via tubing, enabling automatic sample switching and introduction.

[0069] The desalination module includes an ultrapure water tank and an elution solution tank. The ultrapure water tank is connected to the inlet of the metal enrichment column via a third water pump and is used to rinse the metal enrichment column with ultrapure water after the enrichment step to remove residual salts. The rinsed waste liquid is discharged into a waste liquid pool through the outlet of the metal enrichment column. The elution solution tank is connected to the inlet of the metal enrichment column via a fourth water pump and is used to elute the target metal element enriched on the metal enrichment column.

[0070] The detection module includes an inductively coupled plasma mass spectrometer (ICP-MS). The inlet of the ICP-MS is connected to the outlet of the metal enrichment column via a fifth water pump, which is used to receive the eluent and perform qualitative and quantitative analysis of metal elements.

[0071] The control module is electrically connected to the capture module, enrichment module, sample injection module, desalination module, and detection module. The control module coordinates and controls the entire system's operation, particularly the start / stop and flow rate control of each pump.

[0072] This invention achieves highly efficient and automated detection of water desalination by incorporating a capture module, an enrichment module, a sample introduction module, a desalination module, and a detection module, and by utilizing a control module for precise control of each module. The device can sequentially complete the capture, enrichment, introduction, desalination, and final detection of metal ions in water samples, effectively improving the accuracy and efficiency of the detection. Simultaneously, the acquisition unit, processing unit, and control unit within the control module work collaboratively to collect and analyze the operating parameters of each module in real time, promptly detecting and handling anomalies, ensuring the stability and reliability of the entire detection process.

[0073] In some embodiments of this application, the operating parameters of each module collected by the acquisition unit include: the real-time flow rate and real-time pressure of the first, second, third, fourth, and fifth water pumps; and the real-time temperature, real-time pressure, and outlet conductivity of the metal capture column and the metal enrichment column.

[0074] In some embodiments of this application, the processing unit analyzes and processes the operating parameters to determine whether each module is operating normally. If an abnormal operation is determined, the unit sets adjustment parameters for the module based on the operating parameters, including: pre-setting a preset flow rate and preset pressure for each water pump; comparing the real-time flow rate of each water pump with the corresponding preset flow rate, and comparing the real-time pressure of each water pump with the corresponding preset pressure; if the real-time flow rate of each water pump is within the preset flow rate range and the real-time pressure of each water pump is within the preset pressure range, then the corresponding water pump is determined to be operating normally; otherwise, the corresponding water pump is determined to be operating abnormally, and adjustment parameters are set based on the flow rate difference between the real-time flow rate and the preset flow rate of each water pump and the pressure difference between the real-time pressure and the preset pressure of each water pump.

[0075] Specifically, in determining whether each module is operating normally, the processing unit employs advanced algorithm models and logical rules. It doesn't simply check if an isolated data point exceeds a preset range, but comprehensively considers the interrelationships and dynamic trends of various relevant parameters. For example, in monitoring critical equipment like water pumps, detailed and precise preset flow rates and pressure values ​​are pre-set for each pump. These preset values ​​are optimal reference standards derived from extensive experimental data, engineering experience, and theoretical calculations, representing the ideal performance indicators that the water pump should achieve.

[0076] During actual operation, the processing unit collects real-time flow rate and pressure data for each water pump. To ensure data accuracy and reliability, high-precision sensors and stable signal transmission lines are used, enabling the rapid and accurate capture of every subtle change during pump operation. Subsequently, the real-time flow rate of each pump is rigorously compared with its corresponding preset flow rate, and the real-time pressure of each pump is also compared and analyzed with its corresponding preset pressure using the same level of precision.

[0077] This comparison is not a simple numerical judgment, but rather combines multiple techniques such as error tolerance range and time series analysis. For example, considering some minor interference factors that may exist in the actual working environment, such as slight fluctuations in the pipeline or brief fluctuations in power supply voltage, the processing unit sets a reasonable error range. Only when the real-time flow rate or real-time pressure exceeds this error range will it be initially identified as a possible abnormal situation.

[0078] However, if any deviation from the preset values ​​occurs—that is, if the real-time flow rate differs from the preset flow rate or the real-time pressure differs from the preset pressure—the processing unit will immediately initiate an anomaly diagnosis program. This program further analyzes the flow rate difference between the real-time and preset flow rates for each pump, as well as the pressure difference between the real-time and preset pressures for each pump. These differences are not merely simple numerical discrepancies; they contain a wealth of information that may indicate different types of faults or potential problems. For example, a positive and large flow rate difference may mean a blockage in the pipeline or insufficient valve opening; a negative flow rate difference may indicate a decline in pump performance or a leak in the system. Similarly, changes in pressure differences can provide similar clues. Based on the precise interpretation and analysis of these differences, the processing unit will set appropriate adjustment parameters for each pump according to pre-defined adjustment strategies and algorithm models.

[0079] These adjustment parameters may include changing the pump speed, adjusting the valve opening, and optimizing the gain coefficient of the control system. By dynamically adjusting these parameters, the system can promptly correct abnormal pump operation and restore it to its normal operating range as quickly as possible. Moreover, throughout the adjustment process, the processing unit continuously monitors the effects of the adjustments and optimizes the adjustment strategy based on actual conditions to ensure that the system always maintains optimal operating conditions.

[0080] Understandably, by presetting the water pump's flow rate and pressure and comparing them precisely with real-time flow rate and pressure, the pump's operating status can be accurately determined. Once an operational anomaly is detected, adjustment parameters can be quickly set based on the flow rate and pressure differences, thereby promptly regulating the water pump and ensuring the smooth operation of the entire water desalination testing process. This refined control method not only improves testing efficiency but also significantly enhances the accuracy of the test results.

[0081] In some embodiments of this application, the processing unit analyzes and processes the operating parameters to determine whether each module is operating normally, including: the operating parameters include the real-time capture temperature, real-time capture pressure, and capture conductivity at the outlet of the metal capture column; obtaining the adsorbent material of the metal capture column and determining the preset capture temperature of the metal capture column based on the adsorbent material; determining a first acceptable temperature range based on the preset capture temperature; if the real-time capture temperature is within the first acceptable temperature range, then the metal capture column is preliminarily determined to be operating normally; setting a preset capture pressure and determining a first acceptable pressure range based on the preset capture pressure; if the real-time capture pressure is within the first acceptable pressure range, then the metal capture column is secondarily determined to be operating normally; determining whether the reaction is normal based on the capture conductivity at the outlet; if the reaction is normal, then the metal capture column is finally determined to be operating normally; otherwise, the metal capture column is determined to be operating abnormally.

[0082] In this embodiment, the processing unit achieves accurate evaluation of the operating status of the metal capture column through multi-dimensional parameter linkage analysis. Specifically, the system monitors the following key indicators in real time as the basis for judgment: real-time capture temperature (unit: °C): reflecting the binding efficiency of the adsorbent material and the target metal ions; real-time capture pressure (unit: bar): characterizing the resistance characteristics of the fluid passing through the column; capture conductivity at the outlet (unit: μS / cm): indirectly reflecting the concentration of residual ions in the solution.

[0083] Step 1: Calibrate preset values ​​based on the characteristics of the adsorbent material. Assume that a modified silica gel-supported chelating agent (such as iminodiacetic acid resin) is used as the adsorbent material in a certain experiment. According to the performance manual and historical experimental database provided by the material supplier, the system presets its theoretical optimal operating temperature as T0 = 50 ± 2℃. At this time, the processing unit automatically generates a first acceptable temperature range centered on T0 (e.g., 48~52℃). When the sensor detects that the actual operating temperature is within this range (e.g., a measured value of 49.5℃), the preliminary judgment condition is met, indicating that the thermodynamic environment has not significantly deviated from the design conditions, and the adsorption reaction has basic feasibility.

[0084] Step 2: Pressure dynamic threshold verification. For metal trapping columns packed with the same batch of packing material, the process specification requires that their standard operating pressure should be stable around P0=1.5 bar. Considering factors such as pump flow fluctuations, a tolerance of ±0.3 bar (i.e., 1.2~1.8 bar) is allowed. If the online pressure transmitter feedback value is 1.6 bar and the trend is stable without sudden changes, then through secondary judgment, it indicates that the bed pore structure is intact, no blockage or channeling has occurred, and the fluid distribution is good.

[0085] Step 3: Conductivity closed-loop verification of reaction efficiency. To ensure the completeness of the chemical reaction, an online conductivity meter is installed downstream of the column for continuous sampling and analysis. For example, when the initial conductivity of the feed liquid is 800 μS / cm, ideally, the outlet conductivity should drop to below 50 μS / cm after sufficient adsorption. If the actual measured value is 45 μS / cm and remains stable, it proves that most of the target ions have been effectively removed, and the system is ultimately judged to be operating normally. Conversely, if the reading abnormally rises to 120 μS / cm or even higher, it may indicate problems such as adsorption saturation, resin deterioration, or bypass leakage, triggering an alarm and initiating the regeneration procedure.

[0086] Understandably, by comprehensively considering three key parameters of the metal capture column—real-time capture temperature, real-time capture pressure, and capture conductivity at the outlet—the operating status of the metal capture column can be determined comprehensively and accurately. First, a preset capture temperature is determined based on the adsorption material, and a first acceptable temperature range is set for preliminary assessment of the real-time capture temperature. Next, a preset capture pressure is set, and a first acceptable pressure range is determined for secondary assessment of the real-time capture pressure. Finally, a final assessment is made based on the capture conductivity at the outlet. This multi-layered assessment method greatly improves the accuracy and reliability of the judgment. Once an abnormality in the operation of the metal capture column is detected, corresponding measures can be taken promptly to ensure the stability and accuracy of water desalination testing.

[0087] In some embodiments of this application, determining whether the response is normal based on the capture conductivity at the outlet includes: dividing the capture conductivity at the outlet into time intervals, determining the change in capture conductivity at adjacent times; comparing the changes in capture conductivity, determining the minimum value of the change in capture conductivity, and obtaining the time corresponding to the minimum value; if the time corresponding to the minimum value is a time before a predetermined time, the response is determined to be normal; if the time corresponding to the minimum value is a predetermined time, the response is determined to be abnormal.

[0088] Understandably, by dividing the capture conductivity at the outlet into time intervals and calculating the change in capture conductivity at adjacent moments, the dynamic changes in conductivity can be accurately captured. Further comparison of these changes and determination of the minimum value and its corresponding moment allows for accurate assessment of whether the reaction has reached a steady state within the expected timeframe. If the minimum value occurs before the specified moment, it indicates that the reaction has completed ahead of schedule and is in a stable state, thus the reaction is considered normal; conversely, if the minimum value occurs at the specified moment, it indicates that the reaction may not have achieved the expected effect or that there is an anomaly, thus the reaction is considered abnormal. This time-series-based conductivity analysis method not only improves the sensitivity of reaction state assessment but also provides a scientific basis for timely adjustment of detection parameters or implementation of maintenance measures, thereby further ensuring the accuracy and reliability of water desalination detection.

[0089] In some embodiments of this application, if the processing unit determines that the operation is abnormal, it adjusts the parameters of the operation parameter setting module, including: determining the temperature adjustment amount based on the temperature difference between the real-time capture temperature of the metal capture column and the preset capture temperature; determining the capture pressure adjustment amount based on the capture pressure difference between the real-time capture pressure of the metal capture column and the preset capture pressure; and if the reaction is determined to be abnormal, replacing or replenishing the adsorption material of the metal capture column.

[0090] Understandably, by monitoring the capture temperature and pressure of the metal capture column in real time and comparing them with preset values, the adjustment amounts for temperature and pressure can be accurately calculated, thereby achieving precise control of operating parameters. This dynamic adjustment mechanism helps ensure that the metal capture column always operates in optimal condition, improving desalination efficiency. Simultaneously, when an abnormal reaction is detected, timely replacement or replenishment of the adsorption material in the metal capture column can effectively restore the equipment's desalination performance and avoid detection errors caused by adsorption material failure.

[0091] In some embodiments of this application, the processing unit analyzes and processes the operating parameters to determine whether each module is operating normally. If an abnormality is determined, the unit sets adjustment parameters for the module based on the operating parameters, including: the operating parameters include the real-time enrichment temperature, real-time enrichment pressure, and enrichment conductivity at the outlet of the metal enrichment column; acquiring the enrichment material of the metal enrichment column, determining the preset enrichment temperature of the metal enrichment column based on the enrichment material; determining a second acceptable temperature range based on the preset enrichment temperature; if the real-time enrichment temperature is within the second acceptable temperature range, the metal enrichment column is preliminarily determined to be operating normally; and setting a pre- A pre-set enrichment pressure is established, and a second acceptable pressure range is determined based on this pre-set enrichment pressure. If the real-time enrichment pressure is within the second acceptable pressure range, the secondary judgment of the metal enrichment column is determined to be normal. The reaction is then determined based on the enrichment conductivity at the outlet. If the reaction is normal, the final judgment of the metal enrichment column is determined to be normal. Otherwise, the metal enrichment column is determined to be abnormal, and a temperature adjustment is determined based on the temperature difference between the real-time enrichment temperature and the pre-set enrichment temperature. An enrichment pressure adjustment is determined based on the enrichment pressure difference between the real-time enrichment pressure and the pre-set enrichment pressure. The adsorbent material of the metal enrichment column is then replaced or replenished.

[0092] Understandably, by introducing real-time enrichment temperature, real-time enrichment pressure, and outlet enrichment conductivity as operating parameters of the metal enrichment column, and setting a preset enrichment temperature based on the characteristics of the enriched material, this scheme achieves a refined assessment of the metal enrichment column's operating status. Specifically, by constructing a second acceptable temperature range and a second acceptable pressure range, the real-time enrichment temperature and pressure are dually verified. Combined with the normality judgment of the reaction based on the outlet enrichment conductivity, a multi-dimensional and hierarchical operational normality judgment system is formed. When any parameter exceeds the preset range or the reaction is abnormal, the system can quickly calculate the temperature adjustment and enrichment pressure adjustment, and automatically trigger the replacement or replenishment process of the adsorbent material. This series of innovative designs not only improves the operational stability and desalination efficiency of the metal enrichment column, but also effectively extends the service life of the equipment and reduces maintenance costs.

[0093] In some embodiments of this application, determining whether the response is normal based on the enriched conductivity at the outlet includes: dividing the enriched conductivity at the outlet into time intervals, determining the change in enriched conductivity at adjacent times; comparing the changes in enriched conductivity, determining the maximum value of the change in enriched conductivity, and obtaining the time corresponding to the maximum value; if the time corresponding to the maximum value is a time before a predetermined time, the response is determined to be normal; if the time corresponding to the maximum value is a predetermined time, the response is determined to be abnormal.

[0094] Understandably, by dividing time intervals and determining the changes in enriched conductivity at adjacent moments, the dynamic changes in conductivity over time can be captured more accurately. Further comparison of the maximum value of the enriched conductivity change and its corresponding moment provides a quantitative basis for determining the normality of the reaction. If the maximum value occurs before the specified moment, it indicates that the conductivity change is within a controllable range, and the reaction is normal; conversely, if the maximum value occurs exactly at the specified moment, it may mean that abnormal fluctuations have occurred during the reaction process, thus determining that the reaction is abnormal. This method not only improves the accuracy and timeliness of determining the normality of the reaction but also helps to promptly identify and address potential operational problems, ensuring the stability and reliability of the water desalination detection device.

[0095] In some embodiments of this application, the control unit is used to set the initial parameters of each module, including: acquiring the type and concentration of the capture solution, the adsorbent material of the metal capture column, the enrichment material of the metal enrichment column, and the type and concentration of the elution solution; and setting the initial parameters of each module according to the type and concentration of the capture solution, the adsorbent material of the metal capture column, the enrichment material of the metal enrichment column, and the type and concentration of the elution solution.

[0096] Understandably, by acquiring and setting the relevant parameters of the capture solution, metal capture column, metal enrichment column, and elution solution as the initial parameters for each module, it is possible to ensure that the water desalination detection device is in optimal working condition from the initial stage. This personalized setting method based on the actual solution and material characteristics greatly improves the adaptability and detection accuracy of the device.
