Description

Technical Field

[0001] The present invention relates to a wastewater treatment system, and more particularly to a wastewater treatment system and method that couples magnetic separation and advanced oxidation for use in the field of wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of removing pollutants from water using physical, chemical, and biological methods. Its aim is to protect the aquatic environment, safeguard public health, and achieve water resource recycling. However, traditional wastewater treatment methods are ineffective in treating wastewater containing suspended solids, heavy metals, and recalcitrant organic matter, failing to remove these pollutants.

[0003] Chinese patent application CN117247166A discloses an oil and gas field wastewater treatment device and method, employing a three-stage series process of "electrocoagulation-magnetic separation-electrooxidation." This process not only enables the treated oil and gas field wastewater to meet reuse and reinjection requirements but also efficiently purifies it, reducing the concentration of organic pollutants and preventing pollution from subsequent desalination treatment units. Furthermore, the process is short and the treatment cost is low. Chinese patent CN108558116B discloses an integrated wastewater treatment system and method combining electrocoagulation, magnetic flocculation, and multi-stage oxidation. This integrated system can withstand greater variations in water quality and quantity and can be directly used to treat industrial wastewater with high heavy metal and organic matter content, such as electroplating wastewater, desulfurization wastewater, dyeing and printing wastewater, sintering wastewater, and chemical wastewater. It has broad development potential and market prospects.

[0004] While existing processes have achieved the coupled application of magnetic separation and advanced oxidation technologies, effectively removing heavy metals and organic pollutants from wastewater, significant technical bottlenecks remain in practical operation. The optimal pH environments required by the magnetic separation and advanced oxidation units differ significantly (the former is predominantly neutral, while the latter requires strong acidity), making it difficult to guarantee precise pH control during treatment. This not only leads to a substantial increase in the consumption of acid / alkalinity regulators and a significant rise in wastewater treatment costs, but also results in a double decrease in treatment efficiency due to pH fluctuations exceeding the allowable range: on the one hand, it affects the recovery efficiency of magnetic materials during magnetic separation, and on the other hand, it weakens the concentration of hydroxyl radicals generated during advanced oxidation, ultimately leading to a reduction in overall wastewater treatment efficiency. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to precisely control the pH environment of magnetic separation and advanced oxidation coupling in the process of treating sewage, so as to improve sewage treatment efficiency and effect and reduce sewage treatment cost.

[0006] To address the aforementioned issues, this invention provides a wastewater treatment system that couples magnetic separation with advanced oxidation, comprising a pH control mechanism, a pH controller fixedly mounted at the front end of the pH control mechanism, a pH coordination unit within the pH controller, an input terminal of the pH coordination unit connected to a pH data acquisition unit, and an input terminal of the pH data acquisition unit connected to pH sensor signals located on the magnetic separation device and the advanced oxidation device, respectively. The front end of the pH control mechanism is also fixedly equipped with a dynamic imaging component that is connected to the pH controller signal. The left end of the dynamic imaging component is connected to an oxidation driving rod, and the right end of the dynamic imaging component is connected to a magnetic separation driving rod. The output end of the pH data acquisition unit is connected to a pH electrical signal conversion unit, and the pH sensor is connected to the oxidation driving rod and the magnetic separation driving rod respectively through the pH electrical signal conversion unit. The output of the pH coordination processing unit is connected to a pH control unit and a pH dynamic adjustment unit. The outputs of both the pH control unit and the pH dynamic adjustment unit are connected to the pH controller signal. An abnormal feedback component is installed inside the dynamic imaging component. The input of the pH coordination processing unit is also connected to a sensing feedback unit. The inputs of both the sensing feedback unit and the pH dynamic adjustment unit are connected to the abnormal feedback component signal.

[0007] In the aforementioned wastewater treatment system that couples magnetic separation and advanced oxidation, not only can staged control be implemented to meet the precise pH requirements of both devices, but also direct dynamic regulation can be performed based on the pH fluctuations in the actual environment of the magnetic separation and advanced oxidation equipment. This effectively reduces pH volatility, thereby promoting and ensuring the dual efficiency of wastewater treatment and improving the overall efficiency of wastewater treatment.

[0008] As a further improvement of this application, the input end of the pH coordination processing unit is also connected to a parameter setting unit, the input end of which is connected to the touch panel on the pH controller via a signal connection. The output end of the pH coordination processing unit is also connected to a pH display unit and an abnormal alarm unit, the output end of which is connected to the touch panel on the pH controller via a signal connection, and the output end of the abnormal alarm unit is connected to the alarm signal on the pH controller via a signal connection.

[0009] As a further improvement of this application, the oxidation drive rod is connected to the pH sensor installed on the advanced oxidation device via a pH value electrical signal conversion unit, and the magnetic separation drive rod is connected to the pH sensor installed on the magnetic separation device via a pH value electrical signal conversion unit.

[0010] As a further improvement of this application, the dynamic imaging component includes a dynamic sensing shell fixedly disposed at the front end of the pH value control mechanism. Guide tubes connected to and communicating with the dynamic sensing shell are fixedly connected to both the left and right ends. The oxidation driving rod is installed in the guide tube on the left side and slides with the guide tube. The magnetic separation driving rod is installed in the guide tube on the right side and slides with the guide tube. A locking ring is fixedly connected to the middle of the inner wall of the dynamic sensing shell. A differential synchronization component is fixedly connected to the inner end of the locking ring. Both ends of the differential synchronization component extend to the outside of the locking ring and are fixedly connected to a differential trigger block. The right end of the oxidation drive rod extends into the dynamic sensing shell and is fixedly connected to the differential trigger block located on the left side. The left end of the magnetic separation drive rod extends into the dynamic sensing shell and is fixedly connected to the differential trigger block located on the right side.

[0011] As a further improvement of this application, the abnormal feedback component includes an inner limit feedback ring that is fixedly connected to the left and right sides of the locking ring and slidably fitted on the outside of the differential synchronization component. A pair of symmetrically arranged outer limit feedback rings are connected to the inner wall of the dynamic sensing shell, and the outer limit feedback rings are located on the side of the differential trigger block away from the inner limit feedback rings. The input terminals of the sensing feedback unit and the pH dynamic control unit are both connected to the signals of the outer limit feedback rings and the inner limit feedback rings.

[0012] As a further improvement of this application, independent sleeves are fixedly connected to the left and right inner walls of the dynamic sensing shell, and the independent sleeves are located on the outside of the oxidation driving rod and the magnetic separation driving rod, respectively. Independent electromagnetic rings for matching applications are fixedly connected to the left and right inner walls of the independent sleeves, and the output end of the pH coordination processing unit is also connected to the pH value independent control unit. The output end of the pH value independent control unit is connected to the signal of the independent electromagnetic ring.

[0013] As a further improvement of this application, two independent sleeves are arranged close to one end in a sliding configuration with the inner wall of the dynamic sensing shell, and are fixedly connected to the corresponding outer limit feedback ring. A dovetail locking block is fixedly connected to the rear end of the outer limit feedback ring, and a dovetail groove that cooperates with the dovetail locking block is provided on the inner wall of the dynamic sensing shell.

[0014] As another improvement of this application, the differential synchronization device has an adjustment cavity, and the left and right inner walls of the adjustment cavity are fixedly connected to the differential electromagnetic rings. An auxiliary spring is fixedly connected between the two differential electromagnetic rings. The output end of the pH coordination processing unit is also connected to the interval differential application unit, and the output end of the interval differential application unit is connected to the signal of the differential electromagnetic ring.

[0015] In addition, the present invention also provides a wastewater treatment method coupled with magnetic separation and advanced oxidation, comprising the following steps: S1. pH monitoring and control. The pH data acquisition unit monitors the actual pH values ​​in the magnetic separation equipment and the advanced oxidation equipment using pH sensors, and then transmits the data synchronously to the pH coordination processing unit. The pH coordination processing unit determines the pH value within the magnetic separation equipment and the advanced oxidation equipment based on the data. When the pH value in the magnetic separation equipment and the advanced oxidation equipment exceeds the set range, the pH control unit adjusts the pH controller so that the pH controller acts on the pH adjustment mechanism to adjust the wastewater treatment environment of the magnetic separation equipment and the advanced oxidation equipment to bring their pH values ​​within the set range. When the pH value is determined to be within the set range, the dynamic pH control unit is activated and the dynamic control program data is transmitted to it. S2. Dynamic pH sensing, The pH data acquisition unit will synchronously transmit the acquired data to the pH electrical signal conversion unit; The pH value electrical signal conversion unit applies the electrical signal generated by the pH value data in the magnetic separation device to the magnetic separation drive rod, causing it to produce a corresponding deformation action; The pH value electrical signal conversion unit applies the electrical signal generated by the pH value data in the advanced oxidation equipment to the oxidation drive rod, causing it to produce a corresponding deformation action; The actions of the oxidation drive rod and the magnetic separation drive rod act on the dynamic imaging component, causing it to generate a dynamic imaging action. S3. Triggers autonomous regulation. When the dynamic imaging component triggers the abnormal feedback component, the pH dynamic control unit can collect the trigger data of the abnormal feedback component, and then transmit direct control commands to the pH controller based on the trigger data and the corresponding dynamic control program data. The pH controller, based on the instructions transmitted by the pH dynamic control unit, regulates the pH control mechanism to compensate for the pH values ​​in the magnetic separation equipment and the advanced oxidation equipment, and balances the difference between the magnetic separation equipment and the advanced oxidation equipment. S4. Feedback Verification The trigger data of the abnormal feedback component will also be transmitted through the sensing feedback unit. The pH coordination processing unit can monitor and verify the autonomous regulation function of the pH dynamic regulation unit based on the data transmitted by the sensing feedback unit and the pH data acquisition unit. When the effectiveness of autonomous regulation is verified, no regulatory action is generated; When the autonomous regulation function is found to be ineffective or unsatisfactory, the pH controller is directly assisted by the pH regulation unit. The pH values ​​of the magnetic separation equipment and the advanced oxidation equipment are regulated by the pH regulation mechanism, and the difference between the magnetic separation equipment and the advanced oxidation equipment is balanced.

[0016] In summary, the coordinated use of the dynamic imaging component, oxidation drive rod, magnetic separation drive rod, and pH dynamic control unit not only enables precise pH control within the magnetic separation and advanced oxidation equipment during wastewater treatment, allowing for phased control to meet the optimal treatment environment requirements and improve wastewater treatment efficiency, but also allows for direct dynamic control based on pH fluctuations in the actual environment of the magnetic separation and advanced oxidation equipment. This eliminates the need for data analysis and readjustment, increases the response rate, effectively reduces pH fluctuation frequency, and decreases the consumption of acid / alkaline regulators within the pH control mechanism, thereby reducing wastewater treatment costs. This dual approach promotes and ensures improved wastewater treatment efficiency, ultimately enhancing the overall effectiveness of wastewater treatment. Attached Figure Description

[0019] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0020] Implementation method 1: Figure 1 - Figure 10 The wastewater treatment system shown is a magnetic separation and advanced oxidation coupled system, including a pH control mechanism. A pH controller is fixedly installed at the front end of the pH control mechanism. The pH controller is equipped with a pH coordination unit. The input end of the pH coordination unit is connected to a pH data acquisition unit. The input end of the pH data acquisition unit is connected to the pH sensor signals installed on the magnetic separation device 1 and the advanced oxidation device 2, respectively. The front end of the pH control mechanism is also fixedly installed with a dynamic imaging component 4 that is connected to the pH controller signal. The left end of the dynamic imaging component 4 is connected to an oxidation driving rod 5, and the right end of the dynamic imaging component 4 is connected to a magnetic separation driving rod 6. The output end of the pH data acquisition unit is connected to a pH electrical signal conversion unit, and the pH sensor is connected to the oxidation driving rod 5 and the magnetic separation driving rod 6 respectively through the pH electrical signal conversion unit. It should be noted that the oxidation drive rod 5 and the magnetic separation drive rod 6 adopt existing mechanical structures, which are directly referenced here without any changes to their structure and principle. The oxidation drive rod 5 and the magnetic separation drive rod 6 can be driven to change their stroke according to the electrical signal transmitted by the pH value electrical signal conversion unit, thereby realizing the extension or contraction movement within the dynamic sensing shell 41. The oxidation drive rod 5 and the magnetic separation drive rod 6 can be selected as electric push rod structures. The output of the pH coordination unit is connected to a pH control unit and a pH dynamic adjustment unit. The outputs of both the pH control unit and the pH dynamic adjustment unit are connected to the pH controller signal. An anomaly feedback component 7 is installed within the dynamic imaging component 4. The input of the pH coordination unit is also connected to a sensing feedback unit. The inputs of both the sensing feedback unit and the pH dynamic adjustment unit are connected to the anomaly feedback component 7 signal. Through the cooperation of the dynamic imaging component 4, the oxidation drive rod 5, the magnetic separation drive rod 6, and the pH dynamic adjustment unit, precise pH control can be achieved not only during wastewater treatment but also within the magnetic separation device 1 and the advanced oxidation device 2. The system employs phased control to meet the precise pH requirements of both the magnetic separation unit 1 and the advanced oxidation unit 2, thereby enhancing wastewater treatment efficiency. Furthermore, it can directly and dynamically adjust the pH levels based on fluctuations in the actual environment of both units, eliminating the need for data analysis and readjustment. This not only increases the response rate but also effectively reduces pH fluctuation frequency and the loss of acid / alkaline regulators within the pH control mechanism, thereby lowering wastewater treatment costs. Ultimately, it promotes and ensures dual efficiency in wastewater treatment, improving overall wastewater treatment effectiveness.

[0021] Figure 1 and Figure 3 The pH coordination unit is shown to have an input terminal connected to a parameter setting unit, which is connected to the touch panel of the pH controller. The output terminal of the pH coordination unit is connected to a pH display unit and an alarm unit. The output terminal of the pH display unit is connected to the touch panel of the pH controller, and the output terminal of the alarm unit is connected to the alarm on the pH controller. Through the settings of the parameter setting unit, pH display unit, and alarm unit, not only can the high applicability of the magnetic separation device 1 and the advanced oxidation device 2 to wastewater treatment be effectively promoted, and the efficiency of their coupling in the overall wastewater treatment process enhanced, but it can also achieve synergy with technical personnel. This allows for the adjustment of wastewater treatment parameters and pH values ​​to suitability after changes in wastewater properties, and timely generation of warning signals when pH control is abnormal, improving the speed of technical personnel's abnormal response, ensuring the effectiveness of the wastewater treatment process, and reducing resource consumption caused by abnormalities.

[0022] Figure 1 and Figure 3The oxidation drive rod 5 is connected to a pH sensor installed on the advanced oxidation device 2 via a pH value electrical signal conversion unit, and the magnetic separation drive rod 6 is connected to a pH sensor installed on the magnetic separation device 1 via a pH value electrical signal conversion unit. The pH value electrical signal conversion unit can convert the data collected by the pH sensor into electrical signals, thereby effectively acting on the oxidation drive rod 5 and the magnetic separation drive rod 6 to produce appropriate stroke changes. This can effectively promote the dynamic imaging component 4 to monitor the changes in pH value data within the magnetic separation device 1 and the advanced oxidation device 2, and can generate corresponding dynamic regulation based on the actual changes, promoting the accuracy and low fluctuation of pH value during the wastewater treatment process, and fully ensuring the efficiency of the entire wastewater treatment process.

[0023] Figure 4 - Figure 10 The dynamic imaging assembly 4 includes a dynamic sensing shell 41 fixedly installed at the front end of the pH value control mechanism. Both ends of the dynamic sensing shell 41 are fixedly connected to guide tubes 42 that communicate with it. An oxidation driving rod 5 is installed in the guide tube 42 located on the left side and slides with the guide tube 42. A magnetic separation driving rod 6 is installed in the guide tube 42 located on the right side and slides with the guide tube 42. A locking ring 43 is fixedly connected to the middle of the inner wall of the dynamic sensing shell 41. A differential synchronization element 44 is fixedly connected to the inner end of the locking ring 43. The differential synchronization element 44 is made of elastic material and can generate appropriate contraction or elongation deformation along its axis in the opposite direction under the action of the oxidation driving rod 5 and the magnetic separation driving rod 6. Both ends of the differential synchronization element 44 extend to the outside of the locking ring 43 and are fixedly connected to differential trigger blocks 45. The right end of the oxidation driving rod 5 extends into the dynamic sensing shell 41 and is fixedly connected to the differential trigger block 45 located on the left. The left end of the magnetic separation driving rod 6 extends into the dynamic sensing shell 41 and is fixedly connected to the differential trigger block 45 located on the right. The guide tube 42 can control the oxidation driving rod 5 and the magnetic separation... While guiding the movement of the drive rod 6, it can also isolate and protect it, thereby preventing damage to the oxidation drive rod 5 and the magnetic separation drive rod 6 caused by the sewage treatment environment. This fully ensures the sealing of the dynamic sensing shell 41, promotes the durability of the dynamic imaging component 4, the oxidation drive rod 5, and the magnetic separation drive rod 6, and the differential synchronization component 44 can effectively adapt to the pH difference between the magnetic separation device 1 and the advanced oxidation device 2. While effectively monitoring and controlling the pH environment of the magnetic separation device 1 and the advanced oxidation device 2, it can also perform a balancing control through the pH difference reflected by the differential synchronization component 44, thereby ensuring the efficiency and effectiveness of the entire sewage treatment process and reducing the cost and resource consumption of sewage treatment.

[0024] Figure 3 - Figure 10The abnormal feedback component 7 includes an inner limit feedback ring 72 fixedly connected to the left and right sides of the locking ring 43 and slidably fitted onto the outside of the differential synchronization component 44. A pair of symmetrically arranged outer limit feedback rings 71 are connected to the inner wall of the dynamic sensing housing 41, with the outer limit feedback rings 71 positioned on the side of the differential trigger block 45 away from the inner limit feedback rings 72. The input terminals of both the sensing feedback unit and the pH dynamic control unit are signal-connected to the outer limit feedback rings 71 and the inner limit feedback rings 72. The cooperation of the outer limit feedback rings 71, the inner limit feedback rings 72, and the differential trigger block 45 enables magnetic separation... The pH difference between device 1 and advanced oxidation device 2, as well as their respective independent pH values, are monitored and triggered from multiple angles. This ensures the accuracy of pH environment control for both magnetic separation device 1 and advanced oxidation device 2, while also promoting the balance of pH difference between them. This reduces the pH control drop while ensuring wastewater treatment effect, thereby reducing the loss of acid / alkaline regulators, lowering wastewater treatment costs, and effectively ensuring the recovery of magnetic materials during magnetic separation, and promoting the generation of hydroxyl radicals during advanced oxidation.

[0025] Figure 1 - Figure 10 The diagram illustrates that during wastewater treatment using a combination of magnetic separation and advanced oxidation, technicians input relevant technical parameters about the magnetic separation and advanced oxidation processes into the parameter setting unit via a touch panel. These parameters include, but are not limited to, the pH range required for the magnetic separation environment, the pH range required for the advanced oxidation environment, the pH difference range between magnetic separation and advanced oxidation, pH data adjustment data, the properties of acidic and alkaline regulators, the single pumping volume of acid / alkaline regulators, and pH abnormality alarm thresholds. The parameter setting unit converts the parameters and transmits them to the pH coordination unit. Based on the data, the pH coordination unit transmits control commands to the pH control unit and the pH dynamic control unit, enabling the pH control unit to act on the pH controller and control the pH adjustment mechanism. This allows for precise pH adjustment within the magnetic separation device 1 and the advanced oxidation device 2 based on wastewater treatment parameters. The pH dynamic control unit iteratively stores the parameter data it directly controls.

[0026] In the initial stage of wastewater treatment, pH sensors installed in the magnetic separation unit 1 and the advanced oxidation unit 2 can monitor the actual pH value inside in real time. The monitoring data is transmitted to the pH coordination unit through the pH data acquisition unit. The pH coordination unit can monitor and verify the actual pH value inside the magnetic separation unit 1 and the advanced oxidation unit 2, and control the pH controller in real time through the pH control unit. This promotes the pH value inside the magnetic separation unit 1 and the advanced oxidation unit 2 to reach the treatment requirements. While improving the pH value regulation efficiency inside the magnetic separation unit 1 and the advanced oxidation unit 2, it can also effectively improve the regulation accuracy, promote the subsequent wastewater treatment effect, and effectively ensure the recovery rate of magnetic substances in the magnetic separation unit 1 and the generation of hydroxyl radicals in the advanced oxidation unit 2.

[0027] Figure 5 - Figure 10 The diagram illustrates that during the wastewater treatment process of the magnetic separation device 1 and the advanced oxidation device 2, the pH data acquisition unit transmits the received pH data to the pH electrical signal conversion unit. The pH electrical signal conversion unit converts the actual pH data of the magnetic separation device 1 into an electrical signal, which then acts on the magnetic separation drive rod 6, causing it to generate a suitable displacement. This displacement, in turn, causes the differential synchronization element 44 to undergo compression or stretching deformation via the differential trigger block 45. Similarly, the pH electrical signal conversion unit converts the actual pH data of the advanced oxidation device 2 into an electrical signal, which then acts on the oxidation drive rod 5, causing it to generate a suitable displacement. This displacement, in turn, causes the differential synchronization element 44 to undergo compression or stretching deformation via the differential trigger block 45. Synchronizing element 44 generates compression or stretching deformation. The pH dynamic control unit, based on the triggering and disconnecting signals of the outer limit feedback loop 71 and the inner limit feedback loop 72 respectively from the corresponding side difference triggering block 45, realizes the autonomous control of the pH controller. Similarly, the sensing feedback unit, based on the data transmitted from the outer limit feedback loop 71 and the inner limit feedback loop 72, feeds back the pH fluctuation status in the magnetic separation device 1 and the advanced oxidation device 2 to the pH coordination processing unit. The pH coordination processing unit can verify the autonomous control effect based on the received data and output and display the relevant pH data. The specific pH fluctuation and autonomous control situation is as follows: Figure 5This demonstrates that when the pH value changes little within the magnetic separation device 1, the magnetic separation drive rod 6 only causes a small displacement of the differential trigger block 45 and a small deformation of the differential synchronization element 44. Consequently, the differential trigger block 45 does not come into contact with the outer limit feedback ring 71 and the inner limit feedback ring 72 located on its left and right sides. Similarly, when the pH value changes little within the advanced oxidation device 2, the oxidation drive rod 5 only causes a small displacement of the differential trigger block 45 and a small deformation of the differential synchronization element 44. Consequently, the differential trigger block 45 does not come into contact with the differential synchronization element 44. If there is no contact between the outer limit feedback loop 71 and the inner limit feedback loop 72 on its left and right sides, then the pH dynamic control unit will not receive a trigger signal and will not generate a control effect. The sensing feedback unit will feed back the non-contact data to the pH coordination processing unit. The pH coordination processing unit will determine that the pH values ​​in the magnetic separation device 1 and the advanced oxidation device 2 are in a normal state and the pH difference between them is also in a balanced state. Then it will maintain the pH data at this time and display the real-time pH change data to the technicians through the pH display unit and the touch panel.

[0028] Figure 6The diagram shows that the pH value data within the magnetic separation device 1 fluctuates significantly. As the pH value continuously decreases, the pH value electrical signal conversion unit, based on the decreasing pH value transmitted by the pH value data acquisition unit, controls the magnetic separation drive rod 6 to extend to the left via electrical signal conversion. This, in turn, compresses the differential synchronization element 44 through the differential trigger block 45. Furthermore, the differential trigger block 45 abuts against the corresponding inner limit feedback ring 72 located to its left. The inner limit feedback ring 72 transmits the data triggered by the differential trigger block 45 driven by the magnetic separation drive rod 6 to the pH value dynamic control unit and the sensing feedback unit, respectively. In advanced... When the pH value in oxidation device 2 does not change significantly, oxidation drive rod 5 only causes a small displacement of differential trigger block 45 and a small deformation of differential synchronization component 44. Consequently, differential trigger block 45 does not engage with the outer limit feedback loop 71 and inner limit feedback loop 72 located on its left and right sides. Therefore, differential synchronization component 44 undergoes an overall contraction deformation, indicating that the pH difference between magnetic separation device 1 and advanced oxidation device 2 is reduced, which will not significantly affect subsequent pH control (i.e., the difficulty of converting the alkaline environment in magnetic separation device 1 to an acidic environment in advanced oxidation device 2). (and conversion efficiency), thus only pH adjustment is needed. At this time, the pH dynamic control unit and the sensing feedback unit still receive data that both the outer limit feedback loop 71 and the inner limit feedback loop 72 on the side of the oxidation drive rod 5 are disconnected. Therefore, the pH dynamic control unit directly performs autonomous control of the pH controller based on the received data, so that the pH controller controls the alkaline regulator in the pH control mechanism to input into the magnetic separation device 1, increase the pH value in the magnetic separation device 1, restore the alkaline treatment environment, ensure its treatment effect on heavy metals and flocculents in wastewater, and effectively ensure the subsequent magnetic substances The recovery rate; similarly, when the pH value of only one side of the advanced oxidation device 2 fluctuates greatly and the pH value increases, the oxidation drive rod 5 extends to the right under the action of the electrical signal, and drives the differential trigger block 45 to trigger the corresponding inner limit feedback loop 72. The pH value dynamic control unit, through the autonomous control of the pH value controller, inputs the acidic regulator in the pH value control mechanism into the magnetic separation device 1, reduces the pH value in the magnetic separation device 1, restores the acidic treatment environment, ensures its treatment effect on organic matter in wastewater, and effectively ensures the generation of hydroxyl radicals in the advanced oxidation device 2;The pH coordination unit analyzes wastewater quality fluctuations based on data transmitted from the sensor feedback unit. It then uses subsequent feedback data to assess the effectiveness of the pH dynamic control unit's autonomous regulation. This ensures efficient pH control within the magnetic separation unit 1, reducing pH fluctuation frequency, while simultaneously validating the autonomous regulation mechanism. Furthermore, the pH coordination unit displays real-time pH data and autonomous regulation data from both the magnetic separation unit 1 and the advanced oxidation unit 2 to technicians via a pH display unit and touch panel.

[0029] Figure 9This demonstrates that when the pH value data within the magnetic separation device 1 does not change significantly, the magnetic separation drive rod 6 only causes a small displacement of the differential trigger block 45 and a small deformation of the differential synchronization element 44. Consequently, the differential trigger block 45 does not engage with the outer limit feedback loop 71 and inner limit feedback loop 72 located on its left and right sides. Furthermore, when the pH value data within the advanced oxidation device 2 fluctuates significantly and the pH value continuously decreases, the pH value electrical signal conversion unit will control the oxidation drive rod 5 via electrical signal conversion based on the decreasing pH value transmitted by the pH value data acquisition unit. A leftward contraction displacement is generated, which in turn stretches the differential synchronization element 44 through the differential trigger block 45. At this time, the differential synchronization element 44 undergoes an overall elongation deformation, indicating that the pH difference between the magnetic separation device 1 and the advanced oxidation device 2 has increased. This will affect the subsequent pH control process (i.e., the difficulty and efficiency of converting the alkaline environment in the magnetic separation device 1 to the acidic environment in the advanced oxidation device 2). Therefore, it is necessary to coordinate and control the pH values ​​of the magnetic separation device 1 and the advanced oxidation device 2 simultaneously. The differential trigger block 45 and the corresponding external limit feedback located to its left... When ring 71 generates a contact trigger, the outer limit feedback ring 71 transmits the trigger data generated by the differential trigger block 45 driven by the oxidation drive rod 5 to the pH dynamic control unit and the sensing feedback unit respectively. The pH dynamic control unit, based on the received data that the magnetic separation drive rod 6 did not trigger the differential trigger block 45 to trigger the outer limit feedback ring 71 and the inner limit feedback ring 72, and the data that the oxidation drive rod 5 triggered the differential trigger block 45 to trigger the outer limit feedback ring 71, autonomously controls the pH controller, controlling the pH control mechanism to input alkali into the advanced oxidation device 2. The acid regulator increases the pH value, restoring it to an optimal acidic treatment environment, ensuring its effectiveness in treating organic matter in wastewater. It also effectively guarantees the generation of hydroxyl radicals in the advanced oxidation device 2. Furthermore, the acid regulator is introduced into the magnetic separation device 1, causing its pH value to decrease and gradually approach the lower limit of its pH range. This balances the pH difference between the magnetic separation device 1 and the advanced oxidation device 2, preventing a decrease in pH control efficiency and increased consumption of acid / alkaline regulators due to excessive pH differences.Similarly, when the pH value fluctuates significantly on only one side of the magnetic separation device 1 and increases, the magnetic separation drive rod 6 will contract to the right under the influence of the electrical signal. This causes the differential trigger block 45 to trigger the corresponding outer limit feedback loop 71. The pH dynamic control unit, through the autonomous control of the pH controller, controls the pH control mechanism to input acidic regulators into the magnetic separation device 1, causing its pH value to decrease and recover to the optimal alkaline treatment environment. This ensures the treatment effect on heavy metals and suspended solids in wastewater and effectively guarantees the recovery rate of magnetic substances. Simultaneously, an alkaline regulator is input into the advanced oxidation device 2, causing its pH value to increase and gradually approach the upper limit of its pH range. This achieves the desired effect on both the magnetic separation device 1 and the advanced oxidation device 2. The pH balance between the two devices is achieved by balancing the pH difference, preventing a decrease in pH control efficiency and increased consumption of acid / alkaline regulators due to excessive pH difference. The pH coordination unit analyzes wastewater quality fluctuations based on data transmitted from the sensing feedback unit and, based on subsequent feedback data, assesses the effectiveness of the autonomous pH control unit. This ensures efficient pH control within the magnetic separation device 1, reduces pH fluctuation frequency, and effectively verifies the autonomous control mechanism, guaranteeing its effectiveness. Furthermore, the pH coordination unit displays real-time pH data and autonomous control data from both the magnetic separation device 1 and the advanced oxidation device 2 to technicians via a pH display unit and touch panel.

[0030] Figure 7The pH data within the magnetic separation device 1 shows significant fluctuations. As the pH value decreases, the pH electrical signal conversion unit, based on the decreasing pH value transmitted by the pH data acquisition unit, controls the magnetic separation drive rod 6 to extend to the left. This, in turn, compresses the differential synchronization element 44 via the differential trigger block 45. Furthermore, the differential trigger block 45 abuts against the corresponding inner limit feedback ring 72 located to its left. The inner limit feedback ring 72 transmits the data triggered by the differential trigger block 45 driven by the magnetic separation drive rod 6 to the pH dynamic control unit and the sensing feedback unit, respectively. Meanwhile, the pH data within the advanced oxidation device 2... When significant fluctuations occur and the pH value continuously decreases, the pH value electrical signal conversion unit, based on the decreasing pH value transmitted by the pH value data acquisition unit, controls the oxidation drive rod 5 to contract to the left via electrical signal conversion. This, in turn, stretches the differential synchronization element 44 through the differential trigger block 45. The differential trigger block 45 then abuts against the corresponding outer limit feedback ring 71 located to its left. The outer limit feedback ring 71 transmits the trigger data generated by the differential trigger block 45 driven by the oxidation drive rod 5 to the pH value dynamic control unit and the sensing feedback unit, respectively. The pH value dynamic control unit then autonomously adjusts the pH value controller based on the received trigger data. The pH control mechanism introduces alkaline regulators into both the magnetic separation device 1 and the advanced oxidation device 2, increasing their pH values. This gradually restores the pH values ​​in both devices to their optimal levels, ensuring the effectiveness and efficiency of wastewater treatment. Similarly, when the pH value in the magnetic separation device 1 fluctuates significantly and increases, the magnetic separation drive rod 6 will contract to the right under the influence of an electrical signal. This will trigger the differential trigger block 45 to activate the corresponding external limit feedback loop 71. Furthermore, when the pH value in the advanced oxidation device 2 fluctuates significantly on one side, the pH value... When the oxidation drive rod 5 is in an enlarged state, it extends to the right under the action of the electrical signal, and drives the differential trigger block 45 to trigger the corresponding inner limit feedback loop 72. At this time, the pH dynamic control unit and the sensing feedback unit can receive the data. Then, the pH dynamic control unit can autonomously control the pH controller, so that the pH control mechanism can input acidic regulators into the magnetic separation device 1 and the advanced oxidation device 2 respectively, reduce their pH values, and gradually restore the pH values ​​in the magnetic separation device 1 and the advanced oxidation device 2 to the optimal environment, thereby ensuring the effect of the magnetic separation device 1 and the advanced oxidation device 2 on sewage treatment and ensuring sewage treatment efficiency.The pH coordination unit analyzes wastewater quality fluctuations based on data transmitted from the sensor feedback unit. It then uses subsequent feedback data to assess the effectiveness of the pH dynamic control unit's autonomous regulation. This ensures efficient pH control within the magnetic separation unit 1, reducing pH fluctuation frequency, while simultaneously validating the autonomous regulation mechanism. Furthermore, the pH coordination unit displays real-time pH data and autonomous regulation data from both the magnetic separation unit 1 and the advanced oxidation unit 2 to technicians via a pH display unit and touch panel.

[0031] Figure 8 The pH data within the magnetic separation device 1 exhibits significant fluctuations. As the pH value decreases, the pH electrical signal conversion unit, based on the decreasing pH value transmitted by the pH data acquisition unit, controls the magnetic separation drive rod 6 to extend to the left. This, in turn, compresses the differential synchronization element 44 via the differential trigger block 45. Furthermore, the differential trigger block 45 abuts against the corresponding inner limit feedback loop 72 located to its left. The inner limit feedback loop 72 transmits the data triggered by the differential trigger block 45 driven by the magnetic separation drive rod 6 to the pH dynamic control unit and the sensing feedback unit, respectively. Similarly, the pH data within the advanced oxidation device 2 exhibits significant fluctuations. As the pH value increases, the pH electrical signal conversion unit, based on the increasing pH value transmitted by the pH data acquisition unit, controls the oxidation drive rod via electrical signal conversion. 5 generates a rightward elongation displacement, which in turn compresses the differential synchronization element 44 through the differential trigger block 45. The differential trigger block 45 abuts against the corresponding inner limit feedback ring 72 located to its right. The inner limit feedback ring 72 transmits the trigger data generated by the differential trigger block 45 driven by the oxidation drive rod 5 to the pH dynamic control unit and the sensing feedback unit respectively. The pH dynamic control unit performs autonomous control of the pH controller based on the received trigger data, so that the pH control mechanism inputs alkaline regulator into the magnetic separation device 1 to increase its pH value and gradually restore it to the optimal treatment environment, and inputs acidic regulator into the advanced oxidation device 2 to decrease its pH value and gradually restore it to the optimal treatment environment, thereby ensuring the effectiveness of the magnetic separation device 1 and the advanced oxidation device 2 in wastewater treatment and ensuring wastewater treatment efficiency; similarly, Figure 10This illustrates that when the pH value of the magnetic separation device 1 fluctuates significantly and increases, the magnetic separation drive rod 6 will contract to the right under the influence of an electrical signal, triggering the differential trigger block 45 to activate the corresponding outer limit feedback loop 71. Conversely, when the pH value of the advanced oxidation device 2 fluctuates significantly and decreases, the oxidation drive rod 5 will contract to the left under the influence of an electrical signal, triggering the differential trigger block 45 to activate the corresponding outer limit feedback loop 71. The pH dynamic control unit and the sensing feedback unit can receive the data. The pH dynamic control unit can then autonomously regulate the pH controller, allowing the pH control mechanism to input an acidic regulator into the magnetic separation device 1 to decrease its pH value and gradually restore it to the optimal processing environment. Similarly, the pH control mechanism can input an alkaline regulator into the advanced oxidation device 2 to increase its pH value and gradually restore it to the optimal processing environment. The system is designed to ensure the effectiveness of the magnetic separation unit 1 and the advanced oxidation unit 2 in wastewater treatment, guaranteeing wastewater treatment efficiency. It also regulates the pH difference between the two units, preventing the loss of acid / alkaline regulators due to large pH differences. The pH coordination unit analyzes wastewater quality fluctuations based on data transmitted from the sensing feedback unit and assesses the effectiveness of the autonomous pH control unit based on subsequent feedback data. This ensures efficient pH control within the magnetic separation unit 1, reducing pH fluctuation frequency, and effectively verifying the autonomous control mechanism. Furthermore, the pH coordination unit displays real-time pH data and autonomous control data from both units via a pH display unit and a touch panel.

[0032] When the pH coordination treatment unit monitors and verifies the effect of autonomous regulation using feedback data transmitted from the sensing feedback unit and data transmitted from the pH data acquisition unit, if the effect is deemed effective, the data is displayed normally through the pH display unit and touch panel. If the autonomous regulation is deemed ineffective or poor, control commands are simultaneously transmitted to the abnormal alarm unit and pH control unit. This causes the abnormal alarm unit to activate its alarm, alerting technicians to promptly check and adjust the abnormal situation. The pH control unit directly controls the pH controller. The commands from the pH coordination treatment unit have a higher priority than those from the pH dynamic regulation unit. Therefore, after receiving the regulation data transmitted from the pH coordination treatment unit, the pH control unit directly executes the data transmitted by the pH coordination treatment unit to control the pH regulation mechanism and regulate the pH values ​​in the magnetic separation device 1 and the advanced oxidation device 2. This promotes the intelligent function of emergency treatment and coordinates with the actions of technicians to promptly adjust abnormalities and ensure the efficiency of wastewater treatment.

[0033] The second implementation method: Figure 1 - Figure 11 This diagram illustrates a wastewater treatment system coupled with magnetic separation and advanced oxidation. Independent sleeves 8 are fixedly connected to the left and right inner walls of the dynamic sensing shell 41, located outside the oxidation drive rod 5 and the magnetic separation drive rod 6, respectively. Independent electromagnetic rings 81 are fixedly connected to the left and right inner walls of each sleeve 8 for coordinated application. The output of the pH coordination unit is also connected to an independent pH control unit, whose output is signal-connected to the independent electromagnetic rings 81. The coordination of the independent pH control unit and the independent electromagnetic rings 81 effectively achieves applicability control of the pH range of the environments in which the magnetic separation device 1 and the advanced oxidation device 2 are used. This addresses different wastewater properties, increases the applicability of wastewater treatment, and provides self-adaptive control when wastewater properties fluctuate significantly. This ensures the accuracy of pH control at each stage of the wastewater treatment process, promotes applicability, and avoids abnormal pH monitoring and control due to fluctuations in wastewater quality.

[0034] Figure 11 Two independent sleeves 8 are shown close to each other at one end and are slidably disposed on the inner wall of the dynamic sensing shell 41, and are fixedly connected to the corresponding outer limit feedback ring 71. A dovetail locking block is fixedly connected to the rear end of the outer limit feedback ring 71, and a dovetail groove is opened on the inner wall of the dynamic sensing shell 41 to cooperate with the dovetail locking block. The cooperation between the dovetail locking block and the dovetail groove can ensure that the independent sleeves 8 and the outer limit feedback ring 71 can be displaced and deformed under the action of the independent electromagnetic ring 81, while also limiting the position of the outer limit feedback ring 71 to prevent it from moving and getting stuck, thus fully ensuring the effectiveness and accuracy of its subsequent triggering action with the differential trigger block 45.

[0035] Figure 1 - Figure 11 The differential synchronization component 44 has an adjustment cavity, and two differential electromagnetic rings 3 are fixedly connected to the left and right inner walls of the adjustment cavity. An auxiliary spring is fixedly connected between the two differential electromagnetic rings 3. The output end of the pH coordination treatment unit is also connected to the interval differential application unit. The output end of the interval differential application unit is connected to the signal of the differential electromagnetic ring 3. The cooperation between the interval differential application unit and the differential electromagnetic ring 3 can effectively regulate and maintain the pH difference between the magnetic separation device 1 and the advanced oxidation device 2, thereby achieving the requirements of different treatment precision and difference balance. It can also play a role in ensuring the difference between the two in sewage treatment, avoiding the problem of inhibiting the recovery of magnetic materials and the generation of hydroxyl radicals due to excessive or insufficient difference caused by regulation. It can also effectively promote the regulation direction, reduce the consumption of acid / alkalinity regulators, and reduce the cost of the entire sewage treatment process.

[0036] Figure 1 - Figure 11 This demonstrates that during the treatment of wastewater of different properties, technicians can transmit different parameter range data to the parameter setting unit through the control panel according to the treatment requirements. These ranges include the pH range of the environment required by the magnetic separation device 1 and the advanced oxidation device 2, as well as the pH difference range between the magnetic separation device 1 and the advanced oxidation device 2. After receiving this data, the pH coordination processing unit makes a judgment on it. When it is determined that the parameter has changed compared to the previous wastewater treatment, the pH coordination processing unit will make a judgment. A control command is transmitted to the pH independent control unit, causing it to act on two independent electromagnetic rings 81 located in the independent sleeve 8 on either side of the oxidation drive rod 5 or the magnetic separation drive rod 6. When the pH range of the desired environment decreases, the two independent electromagnetic rings 81 in the same independent sleeve 8 generate a repulsive electromagnetic effect, thereby causing the outer limit feedback ring 71 to move towards the differential synchronization element 44, reducing the distance between the corresponding outer limit feedback ring 71 and the inner limit feedback ring 72, and thus reducing the distance between the corresponding differential trigger block 45 and the outer limit feedback ring 71. 1. The triggering distance between the inner limit feedback loop 72 and the outer limit feedback loop 72; When the pH range of the required environment increases, the two independent electromagnetic loops 81 in the same independent sleeve 8 generate an electromagnetic attraction, which in turn drives the outer limit feedback loop 71 to move away from the differential synchronization element 44, increasing the distance between the outer limit feedback loop 71 and the inner limit feedback loop 72 at the corresponding positions, and increasing the triggering distance of the differential trigger block 45 at the corresponding positions between the outer limit feedback loop 71 and the inner limit feedback loop 72, thereby effectively meeting the needs of different pH accuracy ranges and promoting applicability to wastewater of different properties; The system transmits control commands to the interval difference application unit. When the difference decreases, it controls the two 9s located in the difference synchronization element 44 to generate an attractive electromagnetic effect, causing the difference synchronization element 44 to contract, which in turn causes the two difference trigger blocks 45 to move closer together. When the difference increases, it controls the two 9s located in the difference synchronization element 44 to generate a repulsive electromagnetic effect, causing the difference synchronization element 44 to extend, which in turn causes the two difference trigger blocks 45 to move further apart. This allows for the applicability control of the distance between the outer limit feedback loop 71 and the inner limit feedback loop 72 after control, ensuring the effectiveness of subsequent triggering. While applicability to the wastewater properties, it also effectively ensures the effectiveness and timeliness of subsequent monitoring and autonomous control, promotes the coupling effect of magnetic separation device 1 and advanced oxidation device 2 on wastewater treatment, effectively reduces the frequency of pH fluctuations, reduces the loss of acid / alkaline regulators in the pH control mechanism, and thus reduces the cost of wastewater treatment. It can achieve a dual efficiency promotion and guarantee effect on wastewater treatment, improving the overall efficiency of wastewater treatment.

[0037] The third implementation method: Figure 1 - Figure 10 A wastewater treatment method coupling magnetic separation and advanced oxidation is illustrated, based on the wastewater treatment system coupling magnetic separation and advanced oxidation in the first and second embodiments, and includes the following steps: S1. pH monitoring and control. The pH data acquisition unit monitors the actual pH values ​​in the magnetic separation device 1 and the advanced oxidation device 2 using pH sensors, and then transmits the data synchronously to the pH coordination processing unit. The pH coordination processing unit determines the pH value in the magnetic separation device 1 and the advanced oxidation device 2 based on the data. When the pH value in the magnetic separation device 1 and the advanced oxidation device 2 exceeds the set range, the pH controller is adjusted by the pH control unit, so that the pH controller acts on the pH control mechanism to adjust the suitability of the wastewater treatment environment of the magnetic separation device 1 and the advanced oxidation device 2 respectively, so that the pH value is within the set range. When the pH value is determined to be within the set range, the dynamic pH control unit is activated and the dynamic control program data is transmitted to it. S2. Dynamic pH sensing, The pH data acquisition unit will synchronously transmit the acquired data to the pH electrical signal conversion unit; The pH value electrical signal conversion unit applies the electrical signal generated by the pH value data in the magnetic separation device 1 to the magnetic separation drive rod 6, causing it to produce a suitable deformation action; The pH value electrical signal conversion unit applies the electrical signal generated by the pH value data in the advanced oxidation device 2 to the oxidation drive rod 5, causing it to produce a corresponding deformation action. The actions of the oxidation driving rod 5 and the magnetic separation driving rod 6 respectively act on the dynamic imaging component 4, causing it to generate a dynamic sensing imaging action; S3. Triggers autonomous regulation. When the dynamic imaging component 4 triggers the abnormal feedback component 7, the pH dynamic control unit can collect the trigger data of the abnormal feedback component 7, and then transmit direct control commands to the pH controller based on the trigger data and the corresponding dynamic control program data. The pH controller, based on the instructions transmitted by the pH dynamic control unit, regulates the pH control mechanism to compensate for the pH values ​​in the magnetic separation device 1 and the advanced oxidation device 2, and balances the difference between the magnetic separation device 1 and the advanced oxidation device 2. S4. Feedback Verification The trigger data of the abnormal feedback component 7 will also be transmitted through the sensing feedback unit. The pH coordination processing unit can monitor and verify the autonomous regulation function of the pH dynamic regulation unit based on the data transmitted by the sensing feedback unit and the pH data acquisition unit. When the effectiveness of autonomous regulation is verified, no regulatory action is generated; When the autonomous regulation function is verified to be ineffective or unsatisfactory, the pH controller is directly assisted by the pH regulation unit. The pH regulation mechanism regulates the pH values ​​of magnetic separation device 1 and advanced oxidation device 2, and balances the difference between them. This not only enables precise pH regulation within magnetic separation device 1 and advanced oxidation device 2 during wastewater treatment, allowing for staged control based on their optimal treatment environment requirements, thus meeting the precise pH needs of magnetic separation device 1 and advanced oxidation device 2 and improving wastewater treatment efficiency, but also allows for direct dynamic regulation based on pH fluctuations in the actual environment of magnetic separation device 1 and advanced oxidation device 2. This eliminates the need for data analysis and re-regulation, improving the response rate while effectively reducing pH fluctuation frequency and the loss of acid / alkaline regulators in the pH regulation mechanism, thereby reducing wastewater treatment costs. Furthermore, it effectively ensures the recovery of magnetic materials during magnetic separation, promotes the generation of hydroxyl radicals during advanced oxidation, and enhances wastewater treatment efficiency.

[0038] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
