Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically a copper processing wastewater treatment equipment. Background Technology

[0002] Copper processing wastewater treatment equipment is an environmentally friendly device specifically designed to treat copper-containing wastewater generated during copper processing. Through the synergistic effect of physical, chemical, and biological technologies, it achieves efficient removal of heavy metal ions, grease, acid and alkali residues, and organic matter from the wastewater, ensuring that the effluent quality meets national discharge standards.

[0003] In existing technologies, the wastewater mixing devices in copper processing wastewater treatment equipment, whether rotary blades or simple reciprocating flow generators, are fundamentally inadequate because they can only provide single-dimensional fluid shearing action. This results in inherent mixing dead zones and laminar flow regions in the flow field formed within the tank, causing reagent molecules to rely on large-scale circulation and limited turbulent diffusion for distribution. Furthermore, when treating systems such as copper wastewater that are extremely sensitive to local pH and reactant concentrations, a single mixing mode can easily lead to the failure of alkaline solutions or sodium sulfide to disperse homogeneously in an instant. This results in incomplete precipitation of heavy metal ions, loose floc structures, and even local redissolution of complexes, severely restricting the stability of effluent quality and the settling performance of sludge. Summary of the Invention

[0004] The purpose of this invention is to address the fundamental shortcomings of wastewater mixing devices in copper processing wastewater treatment equipment. Whether it is a rotating impeller or a simple reciprocating flow generator, the basic principle is that they can only provide a single-dimensional fluid shearing action. This results in inherent mixing dead zones and laminar flow regions in the flow field formed within the tank, causing reagent molecules to rely on large-scale circulation and limited turbulent diffusion for distribution. Furthermore, when treating systems such as copper wastewater that are extremely sensitive to local pH and reactant concentrations, a single mixing mode can easily lead to the failure of alkaline solutions or sodium sulfide to disperse homogeneously in an instant. This results in incomplete precipitation of heavy metal ions, loose floc structures, and even local redissolution of complexes, severely restricting the stability of effluent quality and the settling performance of sludge. Therefore, this invention proposes a copper processing wastewater treatment device.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The drive device rotates the rotating shaft, which in turn rotates the agitator plate, mixing the wastewater and the reagent. Simultaneously, the rotating shaft drives the double-stage reciprocating rod and its gear one to rotate. Since gear one meshes with a double-sided rack, and the rack is fixed to the wastewater tank, the rotation of gear one, along with the rotating shaft, causes the double-sided rack to rotate, thus rotating the double-stage reciprocating rod. Because the double-stage reciprocating rod is reciprocated to a pair of combined plates, the rotation of the double-stage reciprocating rod causes the pair of combined plates to reciprocate, thereby driving the two sets of mixing plates to reciprocate. The continuous movement and repositioning of the auxiliary plate ensures the overall circulation of the large-scale macroscopic fluid through external rotation, while the continuous movement of the internal mixing plate actively generates high-intensity, high-frequency microscale turbulence and shear within the agitator and its near-field region. This allows the reagent to be instantly torn apart, dispersed, and transported to various areas of the wastewater tank once it enters the mixing zone, eliminating mixing dead zones and achieving instantaneous homogenization of reagent concentration and pH value. This ensures that heavy metals such as copper ions can quickly and completely form stable precipitates.

[0025] 2. When the rotating shaft rotates, it drives the reciprocating rod one and the gear five on it to rotate accordingly. Since gear five meshes with the double-sided rack, the rotation of gear five drives the rotation of the double-sided rack, thereby driving the reciprocating rod one to rotate. Because the reciprocating rod one and the reciprocating block are in a reciprocating connection relationship, and the reciprocating block is limited by the limiting rod, the reciprocating block moves back and forth through the rotation of the reciprocating rod, thereby driving the linkage rod and the material shell to move back and forth. This allows the agent in the material shell to move continuously from the center to the edge of the wastewater tank. At the same time, as the rotating shaft rotates, the agent is evenly distributed in space within the tank. This means that the agent is no longer limited to a fixed point, but can be dynamically and evenly released throughout the entire wastewater tank. Attached Figure Description

Detailed Implementation

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-7As shown, a copper processing wastewater treatment device includes a wastewater tank 1; a support column 2 is fixedly connected to the top of the outer wall of the wastewater tank 1; a drive device 3 is fixedly connected to the top of the outer wall of the support column 2; a rotating shaft 4 is provided at the output end of the drive device 3; a pair of agitator plates 5 are fixedly connected to the outer wall of the rotating shaft 4; a pair of auxiliary plates 6 are fixedly connected to the outer wall of the rotating shaft 4; a pair of double-stage reciprocating rods 7 are rotatably connected to the outer wall of the rotating shaft 4; a gear 8 is fixedly connected to one end of the outer wall of each pair of double-stage reciprocating rods 7. A double-sided rack 9 is fixedly connected to the inner wall of the wastewater tank 1, and a pair of gears 8 mesh with the double-sided rack 9; a pair of combined plates 10 are provided on the outer walls of a pair of double-stage reciprocating rods 7, and the outer walls of the combined plates 10 are slidably connected to the inner wall of the auxiliary plate 6; a set of mixing plates 11 is fixedly connected to the outer walls of the combined plates 10. The driving device 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the stirring plate 5 to rotate, so that the wastewater and the reagent are mixed. The rotating shaft 4 simultaneously drives the double-stage reciprocating rods 7 and the plates on them. The gear 8 rotates accordingly. Since the gear 8 meshes with the double-sided rack 9, and the double-sided rack 9 is fixed on the wastewater tank 1, the gear 8 rotates with the rotating shaft 4 and rotates through the double-sided rack 9, thereby driving the double-segment reciprocating rod 7 to rotate. Since the double-segment reciprocating rod 7 is reciprocatingly connected to a pair of combined plates 10, the rotation of the double-segment reciprocating rod 7 causes the pair of combined plates 10 to reciprocate, thereby driving the two sets of mixing plates 11 to reciprocate and continuously change positions. The rotation of the auxiliary plate 6 ensures the overall circulation of the large-scale macroscopic fluid, while the continuous movement of the mixing plates 11 inside the agitator and its near-field area actively generates high-intensity, high-frequency micro-scale turbulence and shear. Once the reagent enters the mixing area, it can be instantly torn apart, dispersed and transported to various areas of the wastewater tank 1, eliminating the mixing dead zone and achieving instantaneous homogenization of reagent concentration and pH value, ensuring that heavy metals such as copper ions can quickly and completely form stable precipitates.

[0037] The combined plate 10 includes a movable plate 101 and a rotating rod 102; the outer side wall of the rotating rod 102 is rotatably connected to the inner side wall of the movable plate 101; a gear 103 is fixedly connected to the top of the outer wall of the rotating rod 102; a rack 104 is fixedly connected to one side of the outer wall of the auxiliary plate 6 via a connecting plate, and the rack 104 meshes with the gear 103; the movable plate 101 is slidably connected to the auxiliary plate 6; one end of the outer wall of the mixing plate 11 is fixedly connected to the outer side wall of the rotating rod 102; the mixing plate 11 is located in the hollow part of the auxiliary plate 6. Through the combined plate 10 including the movable plate 101 and the rotating rod 102, when the movable plate 101 and the rotating rod 102 reciprocate, the rotating rod 102 drives the gear 103 to move. Because the gear 103 meshes with the rack 104, and the gear 103... The second gear 104 is fixed to the auxiliary plate 6 via a connecting plate. When the second gear 103 moves, it rotates through the second gear 104, thereby driving the rotating rod 102 to rotate. The rotating rod 102 then drives the mixing plate 11 to rotate. The mixing plate 11 rotates significantly with the rotating shaft 4 while moving and rotating, enhancing the mixing effect. The rotation of the stirring plate 5 and the auxiliary plate 6 achieves large-scale fluid circulation. The simultaneous movement and rotation of the mixing plate 11 generates high-intensity, high-frequency microscale turbulence and shear, improving the mixing efficiency of the reagent and wastewater. This ensures the uniform distribution of the reagent in the wastewater and avoids the problem of excessively high or low local reagent concentrations, thereby effectively improving the precipitation effect of heavy metals such as copper ions and making the generated floc structure more compact.

[0038] A set of reciprocating rods 18 is rotatably connected to the outer wall of the rotating shaft 4; a gear 19 is fixedly connected to one end of the outer wall of the reciprocating rod 18, and the gear 19 meshes with a double-sided rack 9; a reciprocating block 20 is provided on the outer wall of the reciprocating rod 18; a set of limiting rods 21 is fixedly connected to the outer wall of the rotating shaft 4, and the set of limiting rods 21 are slidably connected to the set of reciprocating blocks 20 respectively; a linkage rod 22 is provided at the bottom end of the outer wall of the reciprocating block 20; a material shell 23 is fixedly connected to the outer wall of the linkage rod 22 through a connecting block. When the rotating shaft 4 rotates, it drives the reciprocating rod 18 and the gear 19 on it to rotate accordingly. Because the gear 19 meshes with the double-sided rack 9, when the gear 19 rotates, it rotates through the double-sided rack 9, thereby driving the reciprocating rod 18 to rotate. Since the reciprocating rod 18 and the reciprocating block 20 are reciprocatingly connected, and the reciprocating block 20 is limited by the limiting rod 21... The limiting mechanism causes the reciprocating block 20 to move back and forth via the rotation of the reciprocating rod, which in turn drives the linkage rod 22 and the material shell 23 to move back and forth. This allows the agent inside the material shell 23 to move continuously from the center to the edge of the wastewater tank 1. As the rotating shaft 4 rotates, the agent is evenly distributed in space within the tank. This means that the agent is no longer limited to a fixed point, but can be dynamically and evenly released throughout the entire wastewater tank 1. During the reciprocating movement, the material shell 23 not only promotes the initial mixing of the agent and the wastewater, but also covers all areas of the tank through its movement trajectory, effectively avoiding the phenomenon of excessively high or low local agent concentrations. Furthermore, as the rotating shaft 4 continues to rotate, the material shell 23 and the agent inside it also participate in large-scale fluid circulation, further accelerating the diffusion and mixing of the agent in the wastewater.

[0039] A square through groove 12 is provided on one side of the outer wall of the agitator plate 5; a circular rod 13 is rotatably connected to one side of the inner wall of the square through groove 12, and one end of the outer wall of the circular rod 13 extends to the outside of the agitator plate 5; a set of square plates 14 are fixed to the outer wall of the circular rod 13; a gear 15 is fixed to one end of the outer wall of the circular rod 13; an annular rack 16 is fixed to the inner wall of the wastewater tank 1, and the annular rack 16 meshes with the gear 15; a sealing shell 17 is rotatably connected to the bottom end of the outer wall of the annular rack 16, and the sealing shell 17 is rotatably connected to a pair of circular rods 13. When the agitator plate 5 rotates with the rotating shaft 4, the agitator plate 5 drives the circular rod 13 and the gear 15 on it to rotate accordingly. Because the gear 15 meshes with the annular rack 16, and the annular rack... 16 is fixed on the wastewater gear body, so that when the gear 15 rotates, it rotates through the ring rack 16, thereby driving the circular rod 13 and the square plate 14 on it to rotate. Since the rotation direction of the square plate 14 is different from the rotation of the mixing, one rotates vertically and the other rotates horizontally. The two cooperate with each other to form a multi-dimensional fluid shearing action, which promotes the large-scale mixing of wastewater and agent, and makes the fluid form a more uniform overall circulation in the pool. Moreover, at the micro level, the vertical rotation and horizontal rotation intertwine to generate more complex and intense turbulence and shear force, which quickly tears the agent molecules into smaller particles and accelerates their diffusion speed in the wastewater, ensuring that the agent is evenly distributed to every corner of the wastewater pool 1 in a very short time.

[0040] The top of the outer wall of the linkage rod 22 is rotatably connected to the bottom of the outer wall of the reciprocating block 20; a gear 8 24 is fixedly connected to the outer wall of the linkage rod 22; a set of racks 8 25 is fixedly connected to the outer wall of the rotating shaft 4 through a fixing block, and the set of racks 8 25 meshes with a set of gears 8 24 respectively; a set of material shells 23 are alternately distributed with a pair of stirring plates 5 and auxiliary plates 6. When the linkage rod 22 moves with the reciprocating block 20, the linkage rod 22 drives the gears 8 24 on it to move. Because the gears 8 24 mesh with the racks 8 25, and the racks 8 25 are fixedly connected to the outer wall of the reciprocating block 20 through a fixing block, the linkage rod 22 drives the gears 8 24 on it to move. The block is fixed on the rotating shaft 4, so that when the gear 8 24 moves, it rotates through the rack 8 25, thereby driving the linkage rod 22 to rotate. The linkage rod 22 drives the material shell 23 to rotate through the connecting block. As the material shell 23 reciprocates, the material feeding range is expanded with the rotation of the linkage rod 22, which further enhances the dispersion effect of the agent in the wastewater. Moreover, this combination of rotation and reciprocating motion ensures that the agent can be quickly and evenly integrated into the wastewater after being released from the material shell 23, avoiding the accumulation or insufficiency of the agent in a certain area.

[0041] In use, the drive device 3 drives the rotating shaft 4 to rotate, which in turn drives the reciprocating rod 18 and its gear 19 to rotate. Since gear 19 meshes with the double-sided rack 9, its rotation causes the rack 9 to rotate, thus rotating the reciprocating rod 18. Because the reciprocating rod 18 and the reciprocating block 20 are in a reciprocating connection, and the reciprocating block 20 is limited by the limiting rod 21, the reciprocating block 20 moves back and forth through the rotation of the reciprocating rod, thereby driving the linkage rod 22 and the material shell 23 to move back and forth. As the agent inside the material shell 23 moves continuously from the center to the edge of the wastewater tank 1, the rotation of the rotating shaft 4 ensures that the agent is evenly distributed in space within the tank. This means that the agent is no longer limited to a fixed point, but can be dynamically and evenly released throughout the entire wastewater tank 1. Furthermore, during the reciprocating movement of the material shell 23, not only is the initial mixing of the agent and the wastewater promoted, but the movement trajectory also covers all areas of the tank, effectively avoiding the phenomenon of excessively high or low concentrations of the agent in certain areas.

[0042] When the linkage rod 22 moves with the reciprocating block 20, the linkage rod 22 drives the gear 8 24 on it to move. Since the gear 8 24 meshes with the rack 8 25 and the rack 8 25 is fixed to the rotating shaft 4 by the fixing block, the movement of the gear 8 24 causes the rack 8 25 to rotate, thereby driving the linkage rod 22 to rotate. The linkage rod 22 drives the material shell 23 to rotate through the connecting block. As the material shell 23 reciprocates, the rotation of the linkage rod 22 expands the feeding range, further enhancing the dispersion effect of the agent in the wastewater. This combined mode of rotation and reciprocating motion ensures that the agent can be quickly and evenly integrated into the wastewater after being released from the material shell 23, avoiding the accumulation or insufficiency of the agent in a certain area.

[0043] The rotating shaft 4 drives the stirring plate 5 to rotate, mixing the wastewater with the reagent. Simultaneously, the rotating shaft 4 drives the double-stage reciprocating rod 7 and its gear 8 to rotate. Since gear 8 meshes with a double-sided rack 9, and the rack 9 is fixed to the wastewater tank 1, the rotation of gear 8 along with the rotating shaft 4 causes the double-stage reciprocating rod 7 to rotate. Because the double-stage reciprocating rod 7 is reciprocatingly connected to a pair of combined plates 10, the rotation of the double-stage reciprocating rod 7 causes the pair of combined plates 10 to reciprocate, thereby driving the two sets of mixing plates 11 to move back and forth. The continuous motion and constant position change of the auxiliary plate 6 ensures the overall circulation of the large-scale macroscopic fluid, while the continuous motion of the mixing plate 11 inside actively generates high-intensity, high-frequency microscale turbulence and shearing in the agitator and its near-field region. This allows the reagent to be instantly torn apart, dispersed and transported to various areas of the wastewater tank 1 once it enters the mixing area, eliminating the mixing dead zone and achieving instantaneous homogenization of reagent concentration and pH value. This ensures that heavy metals such as copper ions can quickly and completely form stable precipitates.

[0044] The combined plate 10 includes a movable plate 101 and a rotating rod 102. When the movable plate 101 and the rotating rod 102 reciprocate, the rotating rod 102 drives the gear 103 to move. Since the gear 103 meshes with the rack 104 and the rack 104 is fixed to the auxiliary plate 6 through a connecting plate, the movement of the gear 103 causes the rack 104 to rotate, thereby driving the rotating rod 102 to rotate. The rotating rod 102 then drives the mixing plate 11 to rotate. The mixing plate 11 rotates significantly with the rotating shaft 4 while moving and rotating, enhancing the mixing effect. The rotation of the stirring plate 5 and the auxiliary plate 6 achieves large-scale fluid circulation. The simultaneous movement and rotation of the mixing plate 11 generates high-intensity, high-frequency micro-scale turbulence and shear, improving the mixing efficiency of the reagent and wastewater. This ensures the uniform distribution of the reagent in the wastewater and avoids problems of excessively high or low local reagent concentrations, thereby effectively improving the precipitation effect of heavy metals such as copper ions and making the generated floc structure more compact.

[0045] When the stirring plate 5 rotates with the rotating shaft 4, it drives the circular rod 13 and the gear 15 on it to rotate accordingly. Since the gear 15 meshes with the ring rack 16 and the ring rack 16 is fixed on the wastewater tooth body, the rotation of the gear 15 drives the circular rod 13 and the square plate 14 on it to rotate. Since the rotation direction of the square plate 14 is different from the rotation of the mixing, one rotates vertically and the other rotates horizontally. The two cooperate with each other to form a multi-dimensional fluid shearing action, which promotes the large-scale mixing of wastewater and agent, and makes the fluid form a more uniform overall circulation in the pool. Moreover, at the micro level, the vertical rotation and the horizontal rotation intertwine to generate more complex and intense turbulence and shear force, which quickly tears the agent molecules into smaller particles and accelerates their diffusion speed in the wastewater, ensuring that the agent is evenly distributed to every corner of the wastewater pool 1 in a very short time.

[0046] This application utilizes a unique stirring method combined with a special reagent dosing method to enable better mixing of wastewater and reagents.

[0047] A real-time operating condition sensing system is also installed at the bottom of the material shell 23 to perform the following steps:

[0048] S101: Through real-time integration at the bottom of the material shell 23 The sensor and the high-sensitivity copper ion selective electrode simultaneously collect the hydrogen ion activity and heavy metal ion concentration at different radial coordinates within wastewater tank 1.

[0049] The specific implementation of step S101 is as follows: A two-dimensional polar coordinate system reflecting the internal spatial structure of the wastewater tank 1 is established, with the geometric axis of the rotating shaft 4 as the central origin and the axial extension direction of the reciprocating rod 18 as the radial reference axis. An electrode detection group consisting of a real-time pH sensor and a high-sensitivity copper ion selective electrode is embedded in the bottom outer wall of the material shell 23. The electrode detection group is a composite three-electrode detection system encapsulated in a corrosion-resistant polytetrafluoroethylene shell. Internally, it integrates a real-time pH sensor, a high-sensitivity copper ion selective electrode, and a shared silver / silver chloride reference electrode. The real-time pH sensor uses a sensitive glass membrane with high selectivity for hydrogen ions as the measuring end, utilizing the potential difference generated by the difference in ion activity between the inside and outside of the membrane to characterize the acidity or alkalinity of the solution. Its output signal is converted into a digital pH value by a built-in high-input impedance transmitter. The core sensing element of the high-sensitivity copper ion selective electrode is a polycrystalline pressed thin film doped with cuprous sulfide and silver sulfide. It is used to sense the chemical potential of copper ions in wastewater and generate a response potential that conforms to the Nernst equation. This response potential has a linear relationship with the logarithm of the copper ion concentration and is calculated in real time to obtain the corresponding heavy metal ion concentration data. In terms of installation layout, the electrode detection assembly is fixed to the mounting hole at the lower edge of the outer wall of the material shell 23 via a threaded connection structure. Specifically, the sensitive measuring end face of the probe extends vertically downwards 3mm to 10mm from the bottom plane of the material shell 23, and is statically sealed with an acid and alkali resistant fluororubber sealing ring to prevent wastewater from entering the internal circuit of the material shell 23. This also ensures that the detection end face is located in the fluid dynamic sensing zone below the discharge port of the material shell 23. Since the material shell 23 is driven by the drive device 3 to rotate the rotating shaft 4, and is also driven by the reciprocating block 20 to move radially and linearly along the reciprocating rod 18, the electrode detection assembly can traverse the horizontal cross-section of the wastewater tank 1 with a dynamic spiral trajectory. This not only effectively solves the problem of floc adhesion and passivation on the sensor end face by utilizing the relative scouring effect of the fluid, ensuring high linearity of the measurement, but also ensures that the collected data... and The signal can be correlated with the instantaneous radial coordinates fed back by the encoder. A strict spatiotemporal coupling relationship is formed, providing accurate data support for the subsequent construction of radial physicochemical feature vectors. This ensures that the measuring end face extends below the wastewater surface and maintains a preset distance from the discharge port of the material shell 23. When the driving device 3 drives the rotating shaft 4 to rotate, and the reciprocating block 20 drives the material shell 23 to reciprocate between the center and the edge, the system measures the distance at preset sampling intervals using the encoder. Trigger a data acquisition command at each sampling time. The system calculates the instantaneous radial coordinates of the material shell 23 based on the rotational speed and displacement feedback from the encoder. The real-time pH sensor converts the detected hydrogen ion potential signal into a digital pH value, denoted as the first value. pH data at each sampling point The copper ion selective electrode converts the sensed response potential into the corresponding heavy metal ion concentration value, denoted as the first value. Concentration data at each sampling point The acquired instantaneous radial coordinates pH value Copper ion concentration and the corresponding sampling timestamp The data is stored in association to form a multidimensional original dataset, which provides original information on chemical components with spatial coordinate characteristics for subsequent steps.

[0050] S102: Perform spatiotemporal weighted fusion on the collected multidimensional data to extract radial physicochemical feature vectors characterizing the reactivity of wastewater. .

[0051] The specific implementation of step S102 is as follows: retrieve the instantaneous radial coordinates generated in step S101 from the controller's storage unit. pH value Copper ion concentration and sampling timestamp The multidimensional raw dataset is subjected to spatiotemporal weighting, where temporal weighting is achieved by introducing a time decay factor. Constructing weight functions Regarding the distance from the current time Closer and The data is assigned a high trust weight to capture the dynamic evolution trend of chemical reactions within wastewater tank 1 in real time. Spatial weighting refers to the current discharge position coordinates of the extract material shell 23. Calculate the coordinates of each sampling point and The radial distance is calculated, and Gaussian kernel functions are used to perform gain compensation on the near-field data around the discharge port. This highlights the difference in physicochemical gradient between the high-concentration diffusion zone and the distant reaction zone at the data level. Specifically, the kernel bandwidth parameter, which characterizes the effective radius of influence of the radial diffusion of the reagent, is preset according to the wastewater treatment process. For example, the setting is 5cm to 15cm, and the controller extracts the radial coordinates of the current discharge position of the material shell 23 in real time. For any sampling point, calculate its instantaneous radial coordinates. and radial Euclidean distance between And substitute into the Gaussian kernel formula The corresponding spatial weighting coefficients are calculated. Due to the central peak characteristic of the Gaussian function, these weighting coefficients reach a maximum value of 1 at the center of the discharge port and decay exponentially with increasing distance from the discharge port. This is achieved by sampling the original... and By performing dot product operations with the weighting coefficients, the saliency of the data in the near-field region near the discharge port can be artificially enhanced, making it dominant in the feature vector. This highlights the local physicochemical gradient distribution generated at the moment of reagent addition in a complex flow field, accurately identifying the high-concentration reaction core area. Using a multi-sensor data fusion algorithm, the weighted data can then be further processed. and The sequences are nonlinearly mapped and superimposed, and random measurement spikes generated by the vigorous stirring of wastewater are filtered out using a moving average filtering algorithm. Specifically, a fixed-length [data / process] is established within the control unit. ,For example A first-in-first-out (FIFO) data buffer window is used to push the continuous physicochemical sampling data sequence, after gain compensation, into the window in chronological order. At each sampling moment, the algorithm calculates all the data within the current window in real time. The arithmetic mean of the sample points is used as the stable observation value at the current moment. As the sampling period progresses, the oldest data point is automatically discarded each time a new weighted data point is pushed into the window. The smoothing effect of this sliding window generates a low-pass filter, effectively filtering out the non-steady-state voltage spike noise caused by microscale turbulence, mechanical vibration, and sensor electromagnetic interference caused by the high-speed rotation of the stirring plate 5 and mixing plate 11 in the wastewater tank 1. After this filtering process, not only is the interference of outliers eliminated, but the final generated radial physicochemical feature vector is also ensured. The data exhibits a smooth spatial variation trend, providing a structured input matrix with a high signal-to-noise ratio for subsequent steps using the lightweight gradient boosting machine algorithm to perform high-precision regression analysis. The processed smoothed data is then divided at equal intervals along the radial direction of wastewater tank 1. For each feature interval, calculate the statistical mean of the fused data and arrange them radially from the inside out, then encapsulate them into a single feature set. A column vector is defined as a radial physicochemical eigenvector. This allows the scattered, fluctuating dynamic sampling points to be transformed into a spatially structured feature matrix that can characterize the overall pool's reactive activity distribution.

[0052] A decision-making system based on a lightweight gradient booster is also installed on the drive unit 3 to perform the following steps:

[0053] S201: Transform the radial physicochemical eigenvector As input, it is mapped to a pre-built precipitation kinetics prediction model, and a lightweight gradient booster algorithm is used to perform regression analysis on the nonlinear reaction process;

[0054] The specific implementation of step S201 is as follows: retrieve the radial physicochemical feature vector generated in step S102, which serves as a structured dataset reflecting the radial chemical activity gradient distribution of the entire pool. , the radial physicochemical eigenvector The input is fed into the sedimentation kinetics prediction model, which is pre-stored in the controller's storage module and built on a lightweight gradient booster architecture. The mapping process refers to converting the vectors... Each feature dimension corresponds to a feature node in the model's input layer. The specific method of the algorithm for regression analysis of nonlinear reaction processes is as follows: It uses a set of weak learners composed of multiple regression decision trees within the model, employing a depth-limited leaf-growing strategy, to analyze the input vector. For each radial eigenvalue, a feature splitting point search is performed to find the optimal splitting path that minimizes the squared loss function. This is relevant to the copper processing wastewater treatment process. There is a highly complex nonlinear coupling relationship between the local fluctuations of the value, the copper ion precipitation rate, and the floc formation kinetics. Regression analysis maps the high-dimensional feature space to a one-dimensional continuous numerical space to achieve end-to-end fitting of the physicochemical state of wastewater to the reaction trend. In this process, the model uses pre-trained tree weight parameters to weight and evaluate the radial physicochemical data, and calculates the intermediate state prediction parameters that can reflect the current macroscopic trend and microscopic dynamic characteristics of the flow field. This provides robust nonlinear inference results for the accurate and real-time calculation of the optimal reagent flux and precipitation reaction saturation in the subsequent step S202.

[0055] S202: Real-time calculation of the optimal reagent flux parameters and expected precipitation reaction saturation under the current operating conditions, and outputs a matching compensation frequency control command. .

[0056] The specific implementation of step S202 is as follows: The intermediate state prediction parameters, which characterize the current flow field reaction trend, are retrieved from the regression analysis based on the lightweight gradient lift model in step S201. The method for real-time calculation of the optimal reagent flux parameters and the expected precipitation reaction saturation under the current operating conditions is as follows: The intermediate state prediction parameters are mapped to a preset stoichiometric equilibrium model to calculate the optimal reagent flux parameters required to achieve complete reaction under the currently collected copper ion distribution characteristics. The optimal reagent flux parameters refer to the volumetric flow rate of the reagent that the material shell 23 should release into the wastewater tank 1 per unit time. Simultaneously, this is combined with the current radial physicochemical characteristic vector... The gradient calculation determines the expected precipitation saturation, which is the predicted percentage of heavy metal ions converted into a stable precipitate under the current reaction environment. This saturation is used to evaluate the completeness of the reaction and determine whether secondary reagent addition is necessary. Based on the coupled calculation results of the optimal reagent flux parameters and the expected precipitation saturation, a frequency adjustment vector is generated by the controller's control algorithm to correct the actuator's motion state in real time. This adjustment vector is then converted into a matching compensation frequency control command. And outputs compensation frequency control commands to the external drive circuit. Defined as an electrical pulse signal sent to the drive device 3 to dynamically adjust the frequency of the reciprocating block 20 moving along the reciprocating rod 18, the instantaneous discharge density of the material shell 23 on the trajectory from the center to the edge is changed by adjusting the cycle of the reciprocating motion, so as to ensure that the agent is no longer limited to a certain fixed point, but follows the radial direction of the wastewater reactivity.

[0057] The drive unit 3 is also equipped with a dynamic dosing rate compensation system, which is used to perform the following steps:

[0058] S301: Receives compensation frequency control commands output by the decision-making system. And convert it into the target rotational speed offset of the drive unit 3;

[0059] The specific implementation of step S301 is as follows: The system controller receives in real time the compensation frequency control command, which characterizes the dynamic adjustment amplitude, output by the decision system. Receive compensation frequency control commands output by the decision-making system The specific method for converting it into the target rotational speed offset of the drive device 3 is as follows: extract the current reference angular velocity of the drive device 3. Establish a linear mapping gain coefficient between command frequency and machine speed. Through calculation formula Real-time calculation of target rotational speed offset Among them, the compensation frequency control command The drive unit 3 is a servo motor controlled by a frequency converter, which contains a digital signal indicating the adjustment direction and the frequency modulus. The target speed offset is... Defined as the angular velocity component that needs to be added or subtracted from the reference speed of drive unit 3, used to compensate for fluctuations in reagent demand caused by differences in flow field reactivity, the calculated target speed offset is... Compared with the reference angular velocity Vector superposition calculations are performed to generate the final target speed control command, which is then converted into a pulse width modulation signal or an industrial bus control protocol message and output to the power drive module of the drive unit 3. Through real-time offset adjustment of the speed, the circumferential speed of the rotating shaft 4 driven by the drive unit 3 and its linked reciprocating rod 18 is changed around the center of the pool. Since the gear 19 at the end of the reciprocating rod 18 is engaged with the double-sided rack 9 fixed on the inner wall of the wastewater pool 1, the offset of the speed will directly cause the change of the rotational angular velocity of the gear 19. This, in turn, changes the cycle frequency of the reciprocating block 20 moving axially along the reciprocating rod 18 through the reciprocating screw transmission mechanism. Finally, it drives the material shell 23 mounted on the bottom of the reciprocating block 20 to sweep across the radial section of the wastewater pool 1 at a controlled instantaneous speed, thereby achieving precise mechanical compensation for the reagent discharge rate.

[0060] S302: By adjusting the output speed of the drive device 3, the displacement frequency of the reciprocating block 20 moving along the reciprocating rod 18 is dynamically compensated, thereby controlling the instantaneous discharge rate of the material shell 23 during the reciprocating movement.

[0061] The specific implementation of step S302 is as follows: The drive device 3 receives the control command containing the target rotational speed offset issued in step S301, and drives the rotating shaft 4 to rotate by adjusting the instantaneous angular velocity of its output end, thereby driving the reciprocating rod 18 fixed to it to sweep within the wastewater tank 1 at a set revolution rate. The specific method for dynamically compensating the displacement frequency of the reciprocating block 20 along the reciprocating rod 18 by adjusting the output speed of the drive device 3 is as follows: the mechanical meshing constraint between the gear 19 installed at the end of the reciprocating rod 18 and the double-sided rack 9 fixed to the inner wall of the wastewater tank 1 is used to convert the circumferential rotational speed change of the rotating shaft 4 into the rotational speed change of the reciprocating rod 18 around its own axis. The reciprocating block 20 is driven to generate reciprocating linear displacement in the radial direction through the helical lead groove on the surface of the reciprocating rod 18. The displacement frequency is defined as the reciprocating block 20 per unit time. The number of complete round-trip movements from the center point near the rotation axis 4 to the edge of the pool wall is determined by the material shell 23 being rigidly connected to the reciprocating block 20 via the linkage rod 22. The dynamic compensation of the displacement frequency directly changes the sweeping step speed of the material shell 23 on the radial section of the wastewater pool 1, controlling the instantaneous discharge rate of the material shell 23 during the reciprocating movement. The instantaneous discharge rate refers to the ratio of the mass of the agent released by the material shell 23 within a specific time slice to the radial coordinate interval in which it is located at that moment. When the decision system identifies a surge in the reactivity of a local area, it increases the rotation speed through the command drive device 3, causing the reciprocating block 20 to drive the material shell 23 through the area at a higher frequency. This physically increases the frequency and dynamic density of agent release under specific spatial coordinates, realizing on-demand compensation and precise control of the agent concentration at different radial positions within the wastewater pool 1.

[0062] A flow field feedback optimization system based on a deep residual network is also installed on the inner wall of wastewater tank 1 to perform the following steps:

[0063] S401: Use an industrial vision sensor to acquire the floc image sequence of the shear area of ​​the mixing plate 11 in real time, and input it into the deep residual network model for multi-scale feature extraction to quantify the fractal dimension features of the flocs.

[0064] The specific implementation of step S401 is as follows: A high frame rate industrial vision sensor is installed on the inner side wall of the wastewater tank 1 through a waterproof observation window. Its imaging focal plane is calibrated in the strong shear region generated by the overlap of the revolution and reciprocating motion of the mixing plate 11, so as to ensure that the instantaneous dynamic evolution of the flocs generated by the reaction of the reagent and heavy metal ions under the high-speed shear field can be captured. The industrial vision sensor is used to acquire the floc image sequence in this region at a constant sampling frequency, and the image sequence is transmitted to the controller for real-time analysis via a high-speed communication link. The specific method for inputting the image sequence into the pre-constructed deep residual network model for multi-scale feature extraction is as follows: the convolutional layer at the front end of the model is used to downsample the original image to extract the edges of the flocs. Primary spatial features such as edge sharpness and texture details are extracted. Then, a 50-layer deep residual block is used to solve the degradation problem in deep network training by using a cross-layer identity mapping structure. High-level semantic features such as pore structure, morphological topology and aggregation density of flocs are captured under different receptive fields. A feature dimensionality reduction and regression module is connected after the model output layer. Based on the extracted multi-dimensional image features, the spatial occupancy ability of flocs is numerically fitted by combining the box-counting dimension method or the perimeter-area ratio model. The fractal dimension features that characterize the structural complexity and density of flocs are quantified. The fractal dimension features can directly reflect the effect of the current flow field shear force on the growth of flocs, thus providing accurate feedback for the adjustment of double-sided rack 9 and ring rack in the subsequent step S402.

[0065] S402: Calculate the shear force threshold required for the current flow field based on the fractal dimension characteristics, and adjust the relative compensation phase of the double-sided rack 9 and the ring rack 16 accordingly, and optimize the staggered rotation phase of the combined plate 10 and the square plate 14 to enhance microscale turbulence and eliminate laminar dead zones.

[0066] The specific implementation of step S402 is as follows: The fractal dimension features of the flocs obtained in step S401 are input as variables into the shear dynamics matching model pre-stored in the controller. The model calculates the shear force threshold required for the current flow field based on the nonlinear mapping relationship between the fractal dimension and the density of the flocs. Among them, shear force threshold Defined as the critical shear stress required to induce controlled breakup and re-aggregation of flocs in their current morphology into high-density particles, based on the shear stress threshold. The feedback adjustment of the relative compensation phase between the double-sided rack 9 and the ring rack 16 is specifically achieved by using a micro-displacement compensation actuator, such as a high-precision stepper module, installed on the inner wall of the wastewater tank 1 to drive the double-sided rack 9 to make a micro-arc displacement along the circumferential direction of the tank wall, thereby changing its initial meshing origin relative to the ring rack 16 in spatial coordinates, thus generating a phase offset. Based on this phase adjustment, by optimizing the staggered rotation phase of the combined plate 10 and the square plate 14, when the rotating shaft 4 rotates and drives gear 8 and gear 15 to mesh on their respective racks, the mixed plate 11, which performs lateral reciprocating motion, and the square plate 14, which performs vertical rotation, generate a preset interference frequency in the spatial intersection area. This staggered cooperation of opposite rotation phases actively generates high-intensity, high-frequency microscale turbulence and multi-dimensional shear force in the flow field. Utilizing the complex turbulent stress field, it rapidly tears and destroys the inherent laminar dead zone and laminar region within the wastewater tank 1, thereby instantly delivering the reagent molecules to every corner of the tank, achieving optimal reagent concentration and... The instantaneous homogenization of values ​​ensures that heavy metal ions can quickly and completely form a stable precipitate with a tight structure.
