Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a high-gradient magnetic separation circulating rapid coagulation and sedimentation treatment system. Background Technology

[0002] With the continuous increase in industrial and domestic wastewater discharge, the composition of pollutants in water bodies is becoming increasingly complex, placing higher demands on the treatment precision, stability, and adaptability of water treatment processes. High-gradient magnetic separation coagulation sedimentation technology, with its advantages of rapid flocculation and good separation effect, is widely used in wastewater purification. However, in actual engineering operations, operating parameters such as water pollutant load, magnetic powder concentration in the tank, and water temperature are constantly fluctuating dynamically, directly affecting the quality of magnetic floc formation and the coagulation sedimentation treatment effect. Conventional fixed-process control modes are no longer suitable for the complex and ever-changing actual water treatment conditions.

[0003] Traditional high-gradient magnetic separation systems often employ fixed thresholds and fixed parameter settings, making them unable to perform data calibration and adaptive adjustment based on real-time fluctuations, resulting in poor adaptability. Furthermore, traditional technologies cannot integrate the low-temperature characteristics of the water body with the magnetic floc load conditions to optimize reagent dosing, stirring, and magnetic field operation parameters, easily leading to problems such as insufficient reagent dissolution, loose floc formation, floc breakage and dispersion, and magnetic powder desorption. Moreover, traditional systems lack multi-parameter coupled floc state identification mechanisms and closed-loop iterative optimization capabilities, resulting in long-term fixed process parameters that cannot achieve self-optimization and upgrades, leading to unstable effluent quality and low overall treatment efficiency.

[0004] Therefore, it is necessary to design a high-gradient magnetic separation circulating rapid coagulation sedimentation treatment system to solve the problems of low calibration accuracy of operating conditions, insufficient accuracy of load condition classification, and weak correlation between reagent and magnetic field parameter control in existing technologies, which lead to poor water treatment adaptability and unstable treatment effect. Summary of the Invention

[0005] In view of this, the present invention proposes a high-gradient magnetic separation circulating rapid coagulation sedimentation treatment system, which aims to solve the problems of low accuracy of operating condition data calibration, insufficient accuracy of load condition classification, and weak correlation between reagent and magnetic field parameter control in the existing technology, resulting in poor water treatment adaptability and unstable treatment effect.

[0006] This invention proposes a high-gradient magnetic separation circulating rapid coagulation and sedimentation treatment system, comprising: The data acquisition module is used to acquire real-time operating data of the high gradient magnetic separation process and store historical operating data in a database; the real-time operating data includes stirring operation parameters and magnetic field operation parameters. The operating condition adjustment module is connected to the data acquisition module. The operating condition adjustment module calibrates the real-time operating condition data according to the historical operating condition database. The operating condition adjustment module is also used to divide the multi-level magnetic floc load operating conditions according to the calibrated real-time operating condition data, and match the stirring operation parameters according to the multi-level magnetic floc load operating conditions. The reagent adaptation module is connected to the data acquisition module and the operating condition adjustment module respectively. The reagent adaptation module is used to identify the temperature operating condition based on the calibrated real-time operating condition data, and adjust the reagent dosing parameters based on the temperature operating condition identification result. The magnetic field control module is connected to the data acquisition module, the operating condition adjustment module, and the reagent adaptation module, respectively. The magnetic field control module is used to determine the magnetic floc formation state of the high gradient magnetic separation process based on the calibrated real-time operating condition data, stirring operation parameters, and reagent dosing parameters. The magnetic field control module is also used to adjust the current magnetic field operating parameters based on the magnetic floc formation state. The closed-loop calibration module is connected to the data acquisition module, operating condition adjustment module, reagent adaptation module, reagent dispensing module, and magnetic field control module, respectively. The closed-loop calibration module is used to store the magnetic separation operation data after adjustment of each module, and to update the historical operating condition database according to the adjusted magnetic separation operation data.

[0007] Furthermore, the process by which the operating condition adjustment module calibrates real-time operating condition data based on the historical operating condition database includes: The operating condition adjustment module retrieves historical steady-state reference data from the historical operating condition database within the same time interval as the real-time operating condition data, obtains the parameter deviation value between the real-time operating condition data and the historical steady-state reference data, and compares it with a preset deviation threshold. When the parameter deviation value is greater than the preset deviation threshold, the working condition adjustment module calibrates the real-time working condition data according to the preset working condition data calibration mapping table to obtain the calibrated real-time working condition data. When the parameter deviation value is less than or equal to the preset deviation threshold, the operating condition adjustment module does not calibrate the real-time operating condition data.

[0008] Furthermore, the real-time operating data also includes the influent pollutant load and the magnetic powder concentration in the pool, and the parameter deviation values ​​include the pollutant load deviation value and the industry magnetic powder concentration deviation value. The operating condition adjustment module calibrates the real-time operating condition data according to a preset operating condition data calibration mapping table to obtain calibrated real-time operating condition data, including: The operating condition adjustment module compares the pollutant load difference and magnetic powder concentration difference with the preset operating condition data calibration mapping table to obtain the corresponding influent pollutant load adjustment coefficient and the in-pool magnetic powder concentration adjustment coefficient. The operating condition adjustment module uses the product of the influent pollutant load, the magnetic powder concentration in the pool, and the corresponding influent pollutant load adjustment coefficient and magnetic powder concentration adjustment coefficient in the pool as the calibrated influent pollutant load and magnetic powder concentration in the pool, respectively.

[0009] Furthermore, the process by which the operating condition adjustment module divides the magnetic flocculant load conditions into multiple levels based on the calibrated real-time operating condition data includes: The operating condition adjustment module compares the calibrated influent pollutant load and in-pool magnetic powder concentration with preset pollutant load thresholds and magnetic powder concentration thresholds, respectively. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both greater than the corresponding preset threshold, the operating condition adjustment module determines that the process load condition is a high magnetic floc load condition. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both less than the corresponding preset threshold, the operating condition adjustment module determines that the process load condition is a low magnetic floc load condition. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both greater than or less than the corresponding preset threshold, the operating condition adjustment module determines the process load condition as the medium magnetic floc load condition.

[0010] 5. The high-gradient magnetic separation circulating rapid coagulation and sedimentation treatment system according to claim 4, characterized in that the stirring operation parameters include stirring shear strength and stirring operation duration; The process by which the operating condition adjustment module matches the stirring operation parameters according to the multi-level magnetic floc load conditions includes: When the process load condition is a high magnetic floc load condition, the condition adjustment module matches the primary stirring shear intensity with the primary stirring running time. When the process load condition is a medium magnetic floc load condition, the condition adjustment module matches the secondary stirring shear strength with the secondary stirring running time. When the process load condition is a low magnetic floc load condition, the condition adjustment module matches the three-stage stirring shear intensity with the three-stage stirring running time.

[0011] Furthermore, the real-time operating data also includes water temperature data; The process by which the drug adaptation module identifies temperature conditions based on the real-time operating data includes: The agent adaptation module compares the real-time water temperature with a preset low-temperature threshold and determines the current temperature condition based on the comparison result. When the real-time water temperature is lower than the preset low temperature threshold, the agent adaptation module determines that the current temperature condition is a low temperature condition and adjusts the agent dissolution reference time for the current low temperature condition. When the real-time water temperature is greater than or equal to the preset low temperature threshold, the reagent adaptation module determines that the current temperature condition is a normal temperature condition and does not adjust the reagent dissolution reference time for the current normal temperature condition.

[0012] Furthermore, the drug dosing parameters include the drug dosing flow rate and the duration of the drug dosing interval in stages; The process by which the reagent adaptation module adjusts the reagent dosing parameters based on the temperature condition identification results includes: The agent adaptation module acquires the multi-level magnetic floc load conditions divided by the working condition adjustment module, and adjusts the agent dosing flow rate and the agent step-by-step dosing interval according to the multi-level magnetic floc load conditions and temperature conditions. When the operating temperature is low, the agent adaptation module increases the agent dosing flow rate and shortens the time interval for step-by-step agent dosing; When the operating temperature is normal: If the process load condition is a high magnetic floc load condition, the reagent adaptation module increases the reagent dosing flow rate and shortens the reagent step-by-step dosing interval. If the process load condition is a medium magnetic floc load condition or a low magnetic floc load condition, the reagent adaptation module directly adopts the preset reagent dosing flow rate and the preset reagent step-by-step dosing interval.

[0013] Furthermore, the magnetic field control module determines the magnetic floc formation state of the high-gradient magnetic separation process based on calibrated real-time operating data, stirring parameters, and reagent dosing parameters, including: The magnetic field control module integrates the calibrated real-time operating data, stirring operation parameters, and reagent dosing parameters, and identifies them as a multi-parameter coupling feature group. The magnetic field control module retrieves a preset magnetic floc forming state library, obtains the similarity coefficient between the multi-parameter coupling feature group and each preset multi-parameter coupling feature group in the preset magnetic floc forming state library, and obtains the maximum similarity coefficient and its corresponding maximum similar preset multi-parameter coupling feature group. The magnetic field control module takes the preset magnetic floc forming state corresponding to the maximum similar preset multi-parameter coupling feature group as the magnetic floc forming state.

[0014] Furthermore, the preset magnetic floc forming state library includes a first preset multi-parameter coupling feature group and its corresponding first magnetic floc forming state, a second preset multi-parameter coupling feature group and its corresponding second magnetic floc forming state, and a third preset multi-parameter coupling feature group and its corresponding third magnetic floc forming state. The magnetic field control module adjusts the current magnetic field operating parameters according to the forming state of the magnetic flocculant, including: The magnetic field control module determines whether the current magnetic floc forming state meets the standard based on the magnetic floc forming state. When the magnetic floc forming state is the first magnetic floc forming state, the magnetic field control module determines that the current magnetic floc forming state has reached the standard and does not adjust the current magnetic field operating parameters. When the magnetic floc forming state is the second magnetic floc forming state or the third magnetic floc forming state, the magnetic field control module determines that the current magnetic floc forming state has not reached the standard, and adjusts the current magnetic field operating parameters according to the magnetic floc forming state and the process load conditions.

[0015] Furthermore, the magnetic field control module determines that the current magnetic floc forming state has not met the standard, and adjusts the current magnetic field operating parameters according to the magnetic floc forming state and process load conditions, including: When the magnetic floc forming state is the second magnetic floc forming state, the magnetic field control module adjusts the current magnetic field operating parameters to the first magnetic field operating parameters; When the magnetic floc forming state is the third magnetic floc forming state: If the process load condition is a high magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value as the first adjustment value; If the process load condition is a medium magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value as the second adjustment value; If the process load condition is a low magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value as the third adjustment value.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention establishes a complete collaborative control system by setting up a data acquisition module, a working condition adjustment module, a reagent adaptation module, a magnetic field control module, and a closed-loop correction module. Relying on a historical working condition database to calibrate real-time working condition data, it achieves precise classification of multi-level magnetic floc load conditions and adaptation of stirring parameters. It optimizes reagent dosing parameters by linking real-time temperature conditions and process load conditions. At the same time, it accurately identifies the magnetic floc formation state and matches a dynamic magnetic field adjustment strategy through multi-parameter coupling. This effectively solves the defects of traditional process parameter control, poor working condition adaptability, insufficient low-temperature reagent reaction, uncontrollable floc formation quality, and easy desorption of magnetic powder. Furthermore, the closed-loop correction module enables optimal iterative updates of working condition data and self-optimization upgrades of process cycles. This significantly improves the working condition adaptability, floc formation stability, and overall wastewater treatment effect of the high-gradient magnetic separation coagulation sedimentation process, ensuring that the effluent water quality continuously meets standards under complex and fluctuating working conditions.

Detailed Implementation

[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Reference Figure 1-2 In some embodiments of this application, the present invention proposes a high-gradient magnetic separation circulating rapid coagulation and sedimentation treatment system, including: a data acquisition module, an operating condition adjustment module, a reagent adaptation module, and a magnetic field control module.

[0020] The data acquisition module is used to collect real-time operating data of the high gradient magnetic separation process and store historical operating data in a database; the real-time operating data includes stirring operation parameters and magnetic field operation parameters. It is worth noting that the real-time operating data also includes influent pollutant load, magnetic powder concentration in the pool, and water temperature data.

[0021] The operating condition adjustment module is electrically connected to the data acquisition module. The operating condition adjustment module calibrates the real-time operating condition data according to the historical operating condition database. The operating condition adjustment module is also used to divide the multi-level magnetic floc load conditions according to the calibrated real-time operating condition data, and match the stirring operation parameters according to the multi-level magnetic floc load conditions. Specifically, the process by which the operating condition adjustment module calibrates real-time operating condition data based on the historical operating condition database includes: The operating condition adjustment module retrieves historical steady-state reference data from the historical operating condition database within the same time interval as the real-time operating condition data, obtains the parameter deviation value between the real-time operating condition data and the historical steady-state reference data, and compares it with the preset deviation threshold. When the parameter deviation value is greater than the preset deviation threshold, the working condition adjustment module calibrates the real-time working condition data according to the preset working condition data calibration mapping table to obtain the calibrated real-time working condition data. When the parameter deviation is less than or equal to the preset deviation threshold, the operating condition adjustment module does not calibrate the real-time operating condition data.

[0022] It is worth noting that the historical steady-state baseline data of the same sequence interval is from the historical operating condition database. It is consistent with the current operating season, water temperature range, and influent operating period, and the water treatment effluent meets the standards and the magnetic flocs are in excellent steady-state operating condition.

[0023] It is worth noting that the preset deviation threshold is set to 8%.

[0024] Specifically, the parameter deviation values ​​include pollutant load deviation values ​​and industry magnetic particle concentration deviation values; The operating condition adjustment module calibrates the real-time operating condition data according to a preset operating condition data calibration mapping table, obtaining calibrated real-time operating condition data, including: The operating condition adjustment module compares the pollutant load difference and magnetic powder concentration difference with the preset operating condition data calibration mapping table to obtain the corresponding influent pollutant load adjustment coefficient and in-pool magnetic powder concentration adjustment coefficient. The operating condition adjustment module uses the product of the influent pollutant load, the magnetic powder concentration in the pool, and the corresponding influent pollutant load adjustment coefficient and magnetic powder concentration adjustment coefficient in the pool as the calibrated influent pollutant load and magnetic powder concentration in the pool, respectively.

[0025] It is worth noting that the preset operating condition data calibration mapping table stores exclusive adjustment coefficients corresponding to different parameter deviation ranges. Specifically, the adjustment coefficients for parameter deviations of 8% to 15% are 0.92 to 0.98, and the adjustment coefficients for parameter deviations of 15% to 25% are 0.85 to 0.92. The larger the deviation, the greater the correction range of the adjustment coefficients.

[0026] Understandably, during the actual operation of high-gradient magnetic separation, long-term operation of the sensor can easily lead to data drift. Instantaneous turbulence in the water and localized enrichment of magnetic powder can also cause momentary distortion of real-time operating data. Directly using raw data for operating condition judgment and parameter control can result in incorrect operating condition classification, mismatches between stirring and flocculation parameters, ultimately leading to poor floc formation quality and unstable water treatment effects. This embodiment establishes a benchmark calibration mechanism based on historical steady-state baseline data. By quantitatively comparing the deviation between real-time data and baseline data, coefficient calibration is performed on data exceeding the deviation threshold, while normal data with minor fluctuations is directly used. This eliminates data acquisition errors and avoids frequent fluctuations in process parameters caused by invalid calibration, providing a reliable data foundation for accurate classification of subsequent load conditions.

[0027] Specifically, the process by which the operating condition adjustment module divides the magnetic flocculant load conditions into multiple levels based on the calibrated real-time operating condition data includes: The operating condition adjustment module compares the calibrated influent pollutant load and in-tank magnetic particle concentration with the preset pollutant load threshold and magnetic particle concentration threshold, respectively. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both greater than the corresponding preset threshold, the operating condition adjustment module determines the process load condition as a high magnetic floc load condition. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both less than the corresponding preset threshold, the operating condition adjustment module determines the process load condition as a low magnetic floc load condition. When the calibrated influent pollutant load and the magnetic powder concentration in the pool are both greater than or less than the corresponding preset threshold, the operating condition adjustment module determines the process load condition as the medium magnetic floc load condition.

[0028] It is worth noting that the preset pollutant load threshold is 120 mg / L and the preset magnetic powder concentration threshold is 1.0 g / L.

[0029] It is worth noting that when the influent pollutant load and magnetic powder concentration cannot simultaneously meet the conditions for high or low load, i.e., one is high and the other is low or the parameters are in the middle range, the process load is considered balanced and the operation is stable, which is the medium magnetic floc load condition.

[0030] Specifically, the stirring operation parameters include stirring shear strength and stirring operation duration; The process by which the operating condition adjustment module matches the stirring operation parameters according to the multi-level magnetic floc load conditions includes: When the process load condition is a high magnetic floc load condition, the condition adjustment module matches the primary stirring shear intensity with the primary stirring running time. When the process load condition is medium magnetic floc load condition, the condition adjustment module matches the secondary stirring shear intensity and the secondary stirring running time. When the process load condition is a low magnetic floc load condition, the condition adjustment module matches the three-stage stirring shear intensity with the three-stage stirring running time.

[0031] It is worth noting that the first-stage stirring shear strength is 80~90s. -1 The primary mixing cycle lasts 100-120 seconds; the secondary mixing shear strength is 60-75 seconds. -1 The secondary mixing cycle time is 70-90 seconds; the tertiary mixing shear strength is 40-55 seconds. -1 The three-stage stirring operation lasts for 60-70 seconds.

[0032] Understandably, high-load conditions require more pollutants and greater flocculation needs, necessitating high-intensity, long-duration stirring to ensure thorough mixing and reaction of the reagents, magnetic powder, and pollutants. Low-load conditions do not require high-intensity stirring, as excessive stirring can break up fine flocs and increase equipment energy consumption. Medium-load conditions are adapted to conventional stirring parameters to ensure stable flocculation. This technology matches the corresponding stirring shear intensity and stirring duration according to multi-level load conditions, achieving adaptive adaptation of "strong stirring under high load and weak stirring under low load," balancing flocculation effect and operating energy consumption.

[0033] The reagent adaptation module is electrically connected to the data acquisition module and the operating condition adjustment module respectively. The reagent adaptation module is used to identify low temperature operating conditions and normal temperature operating conditions based on the calibrated real-time operating condition data, and adjust the reagent dosing parameters according to the temperature operating condition identification results. Specifically, the reagent adaptation module identifies low-temperature and normal-temperature operating conditions based on real-time operating data, including: The reagent matching module compares the real-time water temperature with the preset low-temperature threshold and determines the current temperature condition based on the comparison result. When the real-time water temperature is lower than the preset low temperature threshold, the reagent adaptation module determines that the current temperature condition is a low temperature condition and adjusts the reagent dissolution reference time for the current low temperature condition. When the real-time water temperature is greater than or equal to the preset low temperature threshold, the reagent adaptation module determines that the current temperature condition is a normal temperature condition and does not adjust the reagent dissolution reference time for the current normal temperature condition.

[0034] It is worth noting that the preset low temperature threshold is 12℃.

[0035] In this embodiment, when the real-time water temperature is <12℃, the system determines that the current operating condition is low temperature. At this time, the water viscosity is high and the hydrolysis and activation rate of the reagent is slow. The reagent adaptation module actively extends the reagent dissolution reference time by 20% to 50% compared to the normal temperature reference time. The lower the water temperature, the greater the compensation range for dissolution time, ensuring that the reagent is fully dissolved and activated, restoring flocculation activity, and compensating for the lag in low-temperature reactions. When the real-time water temperature is ≥12℃, the system determines that the current operating condition is normal temperature. The hydrolysis, diffusion, and reaction rates of the reagent in the water are normal, and no compensation correction is required. The reagent adaptation module directly uses the system's preset standard reagent dissolution reference time without adjustment, ensuring steady-state operation of the process and avoiding unnecessary energy consumption and increased reagent consumption.

[0036] In this embodiment, the reagent dissolution reference time is the standard residence time required for the reagent to completely dissolve, fully activate and achieve optimal flocculation activity in water, which is a fixed reference value of 60s at room temperature.

[0037] Specifically, the pesticide dosing parameters include the pesticide dosing flow rate and the duration of the pesticide dosing interval. The process by which the reagent adaptation module adjusts the reagent dosing parameters based on the temperature condition identification results includes: The reagent adaptation module obtains the multi-level magnetic floc load conditions divided by the working condition adjustment module, and adjusts the reagent dosing flow rate and the reagent step-by-step dosing interval according to the multi-level magnetic floc load conditions and temperature conditions. When the operating temperature is low, the reagent adaptation module increases the reagent dosing flow rate and shortens the reagent dosing interval. When the operating temperature is normal: If the process load condition is a high magnetic floc load condition, the reagent adaptation module increases the reagent dosing flow rate and shortens the reagent step-by-step dosing interval. If the process load condition is a medium magnetic floc load condition or a low magnetic floc load condition, the reagent adaptation module directly adopts the preset reagent dosing flow rate and the preset reagent step-by-step dosing interval.

[0038] It is worth noting that the agent addition flow rate is the volume of coagulant or coagulant aid added per unit time; the agent step-by-step addition interval is the interval between two adjacent agent additions in a multi-stage dosing process, which can ensure that each stage of agent reacts fully and avoid problems such as excessive agent accumulation, poor floc encapsulation, and agent waste.

[0039] It is worth noting that the preset standard reagent dosing flow rate at room temperature is 8L / h, and the preset interval for step-by-step dosing is 15s.

[0040] It is worth noting that when the operating temperature is low, regardless of the current magnetic floc load level, the reagent adaptation module uniformly implements a low-temperature enhanced dosing strategy: increasing the reagent dosing flow rate by 10% to 20% and simultaneously shortening the interval between dosing steps by 3 to 6 seconds. By increasing the reagent dosage per unit time and shortening the dosing interval, the problem of slow water reaction rate and low reagent utilization at low temperatures is compensated for, continuously maintaining the effective reagent concentration in the water and ensuring normal floc aggregation and formation.

[0041] It is worth noting that when the operating temperature is normal, the system adjusts its operation based on the graded differential control of the magnetic floc load: if the magnetic floc load is high, it indicates that the pollutant content in the water is high and the flocculation demand is large. In this case, the reagent matching module increases the reagent dosage by 10% and shortens the step-by-step dosing interval by 5 seconds to enhance the reagent supply and meet the high-load flocculation demand. If the magnetic floc load is medium or low, it indicates that the water pollution load is moderate or low and there is no need to enhance the dosing. In this case, the reagent matching module directly adopts the system's preset standard reagent dosage and preset step-by-step dosing interval, which saves reagent consumption and operating costs while ensuring the treatment effect.

[0042] Understandably, in low-temperature water treatment environments, water viscosity increases significantly, Brownian motion of water molecules weakens, and the hydrolysis rate of coagulants decreases dramatically. For every 10°C decrease in water temperature, the hydrolysis rate can decrease by 2-4 times, easily leading to problems such as insufficient dissolution, delayed activation, poor colloid neutralization and destabilization, and small, loose flocs that are difficult to settle. Traditional magnetic separation dosing systems use fixed dissolution times, fixed dosing flow rates, and fixed intervals, which cannot adapt to the delayed reaction characteristics of chemicals under low-temperature conditions, nor can they dynamically match the dosage according to the pollution load. This results in frequent flocculation failures, effluent exceeding standards, and significant chemical waste during low-temperature seasons and under high-pollution conditions. This embodiment establishes a precise temperature condition identification mechanism to actively compensate for chemical dissolution time under low-temperature conditions. Simultaneously, it couples the three-stage magnetic floc load conditions to differentiate the dosing flow rate and interval, achieving refined adaptive control for low-temperature time compensation, heavy-load dosing, and steady-state energy saving. This completely solves the technical pain points of poor chemical compatibility and unstable low-temperature flocculation in traditional processes.

[0043] The magnetic field control module is electrically connected to the data acquisition module, the operating condition adjustment module, and the reagent adaptation module. The magnetic field control module is used to determine the magnetic floc formation state of the high gradient magnetic separation process based on the calibrated real-time operating condition data, stirring operation parameters, and reagent dosing parameters. The magnetic field control module is also used to adjust the current magnetic field operating parameters according to the magnetic floc formation state. Specifically, the magnetic field control module determines the magnetic floc formation state of the high-gradient magnetic separation process based on calibrated real-time operating data, stirring parameters, and reagent dosing parameters, including: The magnetic field control module integrates calibrated real-time operating data, stirring operation parameters, and reagent dosing parameters, and identifies them as a multi-parameter coupling characteristic group. The magnetic field control module retrieves the preset magnetic floc forming state library, obtains the similarity coefficient between the multi-parameter coupling feature group and each preset multi-parameter coupling feature group in the preset magnetic floc forming state library, and obtains the maximum similarity coefficient and its corresponding maximum similar preset multi-parameter coupling feature group. The magnetic field control module takes the preset magnetic floc forming state corresponding to the maximum similar preset multi-parameter coupling feature group as the magnetic floc forming state.

[0044] It is worth noting that the multi-parameter coupling feature set is a multi-dimensional set of parameters composed of the calibrated influent pollutant load, in-pool magnetic powder concentration, water temperature, stirring shear intensity, stirring duration, reagent dosing flow rate, and reagent dosing interval.

[0045] It is worth noting that the multi-dimensional feature vector cosine similarity algorithm is used to transform the real-time multi-parameter coupled feature group and the preset standard feature group into multi-dimensional vectors. The cosine value of the vector angle is used to quantify the overall fit of the two sets of parameters and output a similarity coefficient in the range of 0 to 1. The closer the value is to 1, the higher the similarity between the current working condition and the preset standard working condition, and the more closely the floc forming state fits the corresponding preset state.

[0046] It is worth noting that this implementation also presets a similarity judgment value of 0.8. When the similarity coefficient is ≥0.8, the match is deemed valid.

[0047] It is worth noting that the magnetic field operating parameters, including magnetic field gradient, magnetic field strength, and magnetic field residence time, directly determine the magnetic field's ability to adsorb, compact, and retain magnetic flocs.

[0048] Specifically, the preset magnetic floc forming state library includes a first preset multi-parameter coupling feature group and its corresponding first magnetic floc forming state, a second preset multi-parameter coupling feature group and its corresponding second magnetic floc forming state, and a third preset multi-parameter coupling feature group and its corresponding third magnetic floc forming state. The magnetic field control module adjusts the current magnetic field operating parameters according to the formation state of the magnetic floc, including: The magnetic field control module determines whether the current magnetic floc forming state meets the standard based on the magnetic floc forming state. When the magnetic floc forming state is the first magnetic floc forming state, the magnetic field control module determines that the current magnetic floc forming state has reached the standard and does not adjust the current magnetic field operating parameters. When the magnetic floc forming state is the second or third magnetic floc forming state, the magnetic field control module determines that the current magnetic floc forming state has not reached the standard, and adjusts the current magnetic field operating parameters according to the magnetic floc forming state and process load conditions.

[0049] It is worth noting that the first magnetic floc forming state is a steady-state standard state. At this time, the floc has high density, uniform particle size, good agglomeration, and no magnetic powder desorption. The magnetic floc has the best settling performance and magnetic field retention performance. It is the standard forming state of the process and there is no need to modify the magnetic field operating parameters.

[0050] The second magnetic floc formation state is a loose and abnormal state. At this time, the overall volume of the floc is too large, the structure is loose, the density is low, the porosity is high, the resistance to water flow shear is weak, and it is easy to have slow settling and slight loss with water. It belongs to the substandard formation state and the magnetic field operation parameters need to be corrected.

[0051] The third magnetic floc forming state is a broken and discrete state. At this time, the floc is broken and disintegrated, exhibiting a fine fragmented and discrete distribution. A large amount of magnetic powder is desorbed, and there are many microparticles that are extremely difficult to settle naturally. This is the most serious forming failure state, which requires correction of the operating parameters of a high-intensity magnetic field.

[0052] Specifically, the magnetic field control module determines that the current magnetic floc forming state has not met the standard, and adjusts the current magnetic field operating parameters according to the magnetic floc forming state and process load conditions, including: When the magnetic floc forming state is the second magnetic floc forming state, the magnetic field control module adjusts the current magnetic field operating parameters to the first magnetic field operating parameters. When the magnetic floc forming state is the third magnetic floc forming state: If the process load condition is a high magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value as the first adjustment value; If the process load condition is a medium magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value to be the second adjustment value; If the process load condition is a low magnetic flocculent load condition, the magnetic field control module increases the current magnetic field operating parameters and determines the increased value to be the third adjustment value.

[0053] It is worth noting that the preset reference magnetic field parameters include a reference magnetic field strength of 350 mT, a reference magnetic field gradient of 120 T / m, and a reference magnetic field dwell time of 8 s. The first, second, and third adjustment values ​​decrease sequentially.

[0054] The specific adjustment process in this embodiment is as follows: When the magnetic flocs are in the second magnetic floc forming state (loose and abnormal), regardless of the load condition level, the magnetic field control module uniformly matches the preset first magnetic field operating parameters. The magnetic field strength is increased to 400mT, the magnetic field gradient is decreased to 105T / m, and the residence time is maintained at 8s. By increasing the field strength, the overall structure of the loose flocs can be compacted. By reducing the gradient, the high shear gradient can be avoided from tearing the loose flocs, reducing the porosity of the flocs, and improving the density and settling performance.

[0055] When the magnetic flocs are in the third magnetic floc forming state (broken and discrete), the magnetic field control module adjusts the parameters upwards in a differentiated manner according to the three-level load conditions: High magnetic floc load condition: The magnetic field control module is matched with the first adjustment value, the magnetic field strength is increased to 450mT, the magnetic field gradient is increased to 135T / m, and the residence time is extended to 12s, so as to maximize the capture of a large number of discrete micro flocs and desorbed magnetic powders under high load. Medium magnetic floc load condition: The magnetic field control module is matched with the second adjustment value, the magnetic field strength is increased to 420mT, the magnetic field gradient is increased to 128T / m, the residence time is extended to 10s, the magnetic field is moderately strengthened, and it is suitable for medium load discrete defects. Low magnetic floc load condition: The magnetic field control module is matched with the third adjustment value, the magnetic field strength is increased to 380mT, the magnetic field gradient is increased to 122T / m, the residence time is extended to 9s, and the magnetic field is slightly corrected, which solves the problem of floc dispersion while avoiding energy waste.

[0056] Understandably, the third magnetic flocs are mostly formed in the form of microparticles and free magnetic powder, which require dual reinforcement of high field strength and high gradient. At the same time, the magnetic field strength and magnetic field gradient are strengthened to maximize the capture of fine escaped particles.

[0057] Understandably, traditional high-gradient magnetic separation processes operate with fixed magnetic field parameters or rely solely on simple start-stop adjustments based on effluent results, failing to anticipate floc formation defects. Since the quality of magnetic floc formation is influenced by multiple coupling factors, including water quality conditions, mixing conditions, and reagent dosage, a single-dimensional parameter cannot accurately reflect the true state of the flocs, easily leading to problems such as loose flocs, breakage and desorption, and microparticle escape, resulting in fluctuations in effluent quality. This embodiment constructs a multi-parameter coupled feature matching and judgment mechanism, integrating all pre-process parameters to build feature groups. Through similarity matching, it accurately identifies three types of floc formation states. Simultaneously, it establishes a two-dimensional magnetic field correction logic based on "floc defect type and load condition level." For stable flocs meeting standards, no intervention is made; for loose or broken flocs, the magnetic field parameters are adjusted differentially according to high, medium, and low load condition gradients, accurately compensating for floc formation defects under different conditions. This significantly improves magnetic floc compaction and magnetic separation retention efficiency, achieving adaptive magnetic field optimization across all operating conditions.

[0058] The closed-loop calibration module is connected to the data acquisition module, operating condition adjustment module, reagent adaptation module, reagent dosing module, and magnetic field control module, respectively. The closed-loop calibration module is used to store the magnetic separation operation data after adjustment of each module and update the historical operating condition database according to the adjusted magnetic separation operation data.

[0059] It is worth noting that the closed-loop correction module establishes a full-domain data interconnection link, and receives all the final operating parameters after the dynamic control is completed by the operating condition adjustment module, reagent adaptation module, reagent delivery module, and magnetic field control module in real time. It fully collects the complete set of optimized magnetic separation operating data, and the data sampling and storage frequency is consistent with the system acquisition frequency of 10Hz, ensuring that the data is complete and without omission.

[0060] It is worth noting that the closed-loop correction module has a built-in high-quality operating condition screening threshold. The preset criteria for judging high-quality and effective operating conditions are effluent turbidity ≤ 5 NTU and SS removal rate ≥ 96%. This threshold is used to screen and evaluate the massive amount of collected operating data. Only high-quality operating condition data that meets the standards, indicates floc formation in the first steady-state state, and shows stable parameter fluctuations are retained. Invalid data with abnormal water quality fluctuations or failed regulation are removed to prevent poor-quality data from interfering with the database benchmark.

[0061] It is worth noting that when the closed-loop calibration module performs database iterative updates, it completes a data collection and review every 24 hours, supplementing the historical operating condition database of the corresponding time series with the selected high-quality new operating condition data; when the similarity of the new high-quality data is better than that of the original old benchmark data (similarity improvement ≥ 0.03), it automatically replaces the original steady-state benchmark data, and synchronously updates the matching parameters of the operating condition calibration mapping table and the preset floc feature library, thus completing the full-chain benchmark iterative optimization.

[0062] It is understandable that this embodiment sets up an independent closed-loop correction module, which fully connects to all functional modules, collects complete operating data after each adaptive adjustment in real time, identifies high-quality and effective operating condition data through preset filtering rules, automatically iterates and updates the historical operating condition database, and continuously optimizes the data calibration mapping table, feature matching template, and operating condition threshold benchmark. This ensures that the system control benchmark always fits the actual operating conditions on site, enabling the system to learn autonomously, iterate on its own, and operate accurately for a long time, greatly improving the long-term operating stability and operating condition adaptability of the equipment.

[0063] Understandably, this invention first achieves accurate correction of real-time operating data through time-series benchmark comparison and deviation calibration. It then precisely divides the magnetic floc load into high, medium, and low levels based on the coupling of pollutant load and magnetic powder concentration, and gradient-matches the corresponding stirring parameters. Simultaneously, it adaptively adjusts the reagent dissolution time, dosing flow rate, and step-by-step dosing interval based on both water temperature and load conditions. Furthermore, it accurately identifies different magnetic floc formation defect states through multi-parameter coupling feature group similarity matching. Finally, it differentiates and gradients the magnetic field strength, magnetic field gradient, and magnetic field residence time for two types of abnormal formation states: loose and broken, achieving steady-state instability and precise defect compensation. The refined magnetic field control, relying on the closed-loop correction module to collect high-quality operating data and iteratively update the historical operating condition database, enables the system to have long-term autonomous learning and adaptive optimization capabilities. This significantly improves the operational stability and adaptability of the magnetic separation coagulation sedimentation process under all seasons and load conditions, significantly optimizes the density of magnetic floc formation and sedimentation separation effect, effectively reduces effluent turbidity and improves pollutant removal rate, while avoiding ineffective reagent addition and excessive equipment operation. It achieves the optimal balance between water treatment effect and energy and reagent consumption, greatly improving the intelligent, refined and long-term operating performance of the high-gradient magnetic separation process, and adapting to the stable treatment needs of various complex water qualities and seasonal conditions.

[0064] It is understandable that this embodiment effectively solves the technical defects of traditional high-gradient magnetic separation processes, such as distorted operating data acquisition, rigid parameter control, poor adaptability to water temperature and water quality conditions, unstable magnetic floc formation quality, coarse adjustment of magnetic field parameters, lack of autonomous optimization capability of the system, large fluctuations in treatment effect under high and low load and low temperature conditions, and waste of chemical and energy consumption, through a full-process collaborative control system of data acquisition, operating condition calibration, load classification, adaptive control of reagents, precise matching of magnetic field and closed-loop self-correction.
