Description

TECHNICAL FIELD

[0001] The present application relates to a kind of electronic grade hydrogen peroxide wastewater grading processing device and processing method. BACKGROUND

[0002] Electronic grade hydrogen peroxide is widely used in high-precision production scenarios such as semiconductor chip manufacturing, integrated circuit packaging and photovoltaic component processing as a key cleaning and etching agent in the electronics industry. During its use, industrial wastewater containing unreacted hydrogen peroxide, organic additives, trace metal ions and particulate impurities is generated. This type of wastewater has complex pollutant composition and strict purity requirements. It not only needs to meet the strict standards of environmental protection departments for pollutant discharge, but also needs to be recycled after deep treatment in some scenarios to meet the dual requirements of water resource recycling and processing precision in the electronics industry.

[0003] However, the existing electronic grade hydrogen peroxide wastewater treatment technology and device still has many problems to be solved:

[0004] 1. Limited processing architecture: Traditional processing devices mostly use single-stage tank processing mode. The reaction path of wastewater and treatment and purification materials is short, and the contact time is limited, making it difficult to achieve deep removal of pollutants. The purification effect often cannot meet the high-purity processing requirements of electronic grade wastewater, resulting in difficulty in meeting the impurity content and pollutant concentration of treated wastewater, limiting the feasibility of subsequent discharge or recycling;

[0005] 2. Insufficient mixing disturbance: The stirring mechanism of existing devices is mostly designed with single rotating stirring blade, which can only achieve local stirring of the bottom layer of the tank, and is prone to form laminar flow state and mixing blind area, resulting in uneven contact between wastewater and treatment agent, and insufficient reaction in local area, which seriously affects the pollutant removal efficiency. At the same time, it is difficult to break the material deposition and vortex dead zone during stirring, further reducing the stability of the treatment effect;

[0006] 3. Poor coordination between feeding and disturbance: The feeding system of traditional devices mostly uses independent driving mechanism (such as solenoid valve, quantitative pump), which lacks mechanical linkage with stirring and disturbance process, and cannot adaptively adjust the feeding amount and feeding time according to the reaction rhythm in the tank. This not only easily leads to secondary pollution caused by excessive treatment materials, or causes treatment efficiency to decay due to insufficient addition of raw materials, but also increases the structural complexity and operating energy consumption of the equipment. Therefore, the present application proposes an electronic grade hydrogen peroxide wastewater grading processing device and processing method to solve the above problems. SUMMARY

[0028] The bottom end of the discharging rod is provided with a fixed plate connected with the reinforcing ring.

[0029] A processing method of an electronic-grade hydrogen peroxide wastewater grading treatment device, comprising the following steps:

[0030] S1. Device start-up and raw material pre-setting:

[0031] The electronic-grade hydrogen peroxide wastewater is introduced into the first group of treatment tank bodies, and the feeding pipe at the top end of the feeding tank is supplemented with treatment and purification raw materials. After the pre-setting of the raw materials is completed, the feeding pipe is closed;

[0032] Start the servo drive motor on the treatment cover plate, and through the transmission connection with the stirring shaft, accurately control the rotation speed and start-stop timing of the stirring shaft, and provide stable power for the subsequent collaborative process;

[0033] S2. Single-tank three-stage collaborative disturbance treatment:

[0034] When the stirring shaft rotates, the stirring blades at the bottom thereof perform full-domain stirring on the wastewater and pre-set raw materials in the tank. Meanwhile, the lifting helix on the outer wall of the stirring shaft and the driving helical groove of the connecting ring are adaptively transmitted, converting the rotary motion into axial lifting motion of the connecting ring, and driving the disturbance ring to move up and down along the two groups of symmetrically arranged treatment pipes through the multiple evenly distributed connecting rods;

[0035] The disturbance ring is in close contact with the inner wall of the treatment tank body, and the reaction residues and scale attached to the inner wall are scraped off during the lifting process, and the laminar flow state is broken to form a three-dimensional disturbance flow field in the whole tank;

[0036] And when the reinforcing ring on the connecting rod moves synchronously with the disturbance ring, the rotating impeller inside the reinforcing ring rotates autonomously under the impact of fluid, forming a three-level coordinated disturbance system of stirring blade bottom stirring, disturbance ring three-dimensional disturbance and rotating impeller adaptive precise disturbance, which ensures that the wastewater and the treatment raw materials are fully mixed and reacted;

[0037] S3. Disturbance feeding adaptive linkage:

[0038] During the upward movement of the disturbance ring, the discharge rod rigidly connected with the fixed plate is lifted along the axis synchronously, lifting the blocking plate in the discharge pipeline on the feeding tank, so that the treatment and purification raw materials are directed to fall into the core reaction zone along the discharge pipeline towards the inner cavity of the tank body;

[0039] When the disturbance ring descends, the blocking plate closes the discharge pipeline under the elastic resetting action of the supporting spring, stopping the feeding, and realizing the adaptive matching of the feeding action and the disturbance rhythm;

[0040] S4. Graded deep treatment and transfer:

[0041] After the first group of treatment tanks completes the preset treatment duration, the transfer pump body on the connecting pipeline is started to transfer the pretreated wastewater to the next group of treatment tanks, and steps S2-S3 are repeated, so that the reaction path and contact time are prolonged through the series connection of multiple groups of treatment tanks, and after the impurity content and pollutant concentration of the wastewater meet the standards, the discharge or recycling process is performed.

[0042] As an improvement of the above technical solution, in step S2, the linkage logic of the three-level coordinated disturbance is that the rotation speed of the stirring blade and the lifting frequency of the disturbance ring are accurately synchronized through the servo drive motor, the autonomous rotation speed of the rotating impeller is dynamically adapted to the lifting speed of the disturbance ring and the fluid flow rate in the tank, and the three form a full-area disturbance effect without mixing blind area;

[0043] In step S3, the discharge rod and the discharge pipeline are coaxially arranged to ensure that the coaxial error of the opening and closing action of the blocking plate is ≤0.5mm, and the feeding amount is positively correlated with the lifting frequency of the disturbance ring and is adaptively adjusted to avoid secondary pollution caused by excessive treatment raw materials or treatment efficiency decay caused by insufficient addition;

[0044] In step S2, the treatment pipeline directs the auxiliary treatment medium into the tank through the treatment port, and the delivery direction of the treatment medium is inversely arranged with the lifting direction of the disturbance ring, which strengthens the mixing uniformity of the medium and the wastewater, and the treatment pipeline forms bidirectional guiding constraint on the movement track of the disturbance ring, ensuring that the contact pressure between the disturbance ring and the inner wall of the treatment tank is uniformly distributed.

[0045] Compared with the prior art, the beneficial effects of the present application are:

[0046] Through the cascade type hierarchical processing architecture constituted by multiple groups of processing tank bodies and connecting pipelines and conveying pump bodies, the electronic grade hydrogen peroxide wastewater can be transported and repeatedly processed step by step, the reaction path and the contact time of the wastewater and the processing and purification raw materials are prolonged, the pollutant removal effect is effectively strengthened, the technical problems that the existing single-stage processing device has insufficient purification depth and is difficult to meet the high-purity processing requirements of electronic grade wastewater are solved, and it is ensured that the impurity content, pollutant concentration and other indicators of the wastewater after processing meet the environmental protection emission and subsequent recycling standards of the electronic grade application scene.

[0047] When the stirring shaft rotates, on the one hand, the wastewater and the processing and purification raw materials in the processing tank body are directly stirred and mixed to provide basic power for the reaction; on the other hand, through the adaptive cooperation of the driving assembly and the disturbance ring, the rotary motion of the stirring shaft is converted into the up-down lifting motion of the disturbance ring, and the disturbance ring is in close contact with the inner wall of the processing tank body, which can not only break the laminar flow state of the wastewater and the processing agent, form a three-dimensional disturbance flow field, and avoid the phenomenon of insufficient reaction in local areas, but also can scrape off the reaction residues and impurities attached to the inner wall of the processing tank body, prevent the inner wall from being scaled to affect the processing efficiency, and ensure the continuity and stability of the hierarchical processing process.

[0048] Relying on the linkage design of the disturbance ring and the feeding tank, without additional independent feeding driving mechanism, the feeding process can be triggered synchronously through the lifting motion of the disturbance ring, realizing the mechanical linkage and cooperation of stirring, disturbance and feeding. On the one hand, this design simplifies the overall structure of the device, reduces the number of power sources, and reduces the equipment manufacturing cost, operation energy consumption and later operation and maintenance difficulty; on the other hand, the amount and timing of the processing and purification raw materials can be accurately matched according to the disturbance rhythm, avoiding secondary pollution caused by excessive processing agent or processing effect attenuation caused by insufficient addition, further optimizing the reaction conditions of hierarchical processing, and improving the stability of overall processing efficiency and processing quality.

[0068] In the embodiment, when the electronic grade hydrogen peroxide wastewater is treated, the electronic grade hydrogen peroxide wastewater is introduced into a group of treatment tank bodies 10, the electronic grade hydrogen peroxide wastewater is treated by the group of treatment tank bodies 10, and after the treatment is completed, the electronic grade hydrogen peroxide wastewater is introduced into another group of treatment tank bodies 10 for treatment again, and the above steps are repeated for grading treatment;

[0069] When the electronic grade hydrogen peroxide wastewater is treated in the treatment tank body 10, the stirring shaft 11 rotates to stir the electronic grade hydrogen peroxide wastewater and the treatment and purification raw materials in the treatment tank body 10, and simultaneously drives the driving assembly 60 to operate, so that the disturbance ring 50 ascends and descends in the treatment tank body 10 while rotating with the stirring shaft 11, and drives the feeding tank 30 to perform a feeding process;

[0070] The series grading treatment architecture formed by the plurality of treatment tank bodies 10, the connecting pipeline 40, and the conveying pump body 41 enables the electronic grade hydrogen peroxide wastewater to be transported and treated repeatedly, prolongs the reaction path and contact time of the wastewater and the treatment and purification raw materials, effectively enhances the pollutant removal effect, solves the technical problems of insufficient purification depth of the existing single-stage treatment device and difficulty in meeting the high-purity treatment requirements of electronic grade wastewater, and ensures that the impurity content, pollutant concentration, and other indicators of the treated wastewater meet the environmental protection emission and subsequent recycling standards of the electronic grade application scenario;

[0071] When the stirring shaft 11 rotates, on the one hand, it directly stirs and mixes the wastewater and the treatment and purification raw materials in the treatment tank body 10 to provide the basis power for the reaction; on the other hand, through the matching of the driving assembly 60 and the disturbance ring 50, the rotating motion of the stirring shaft 11 is converted into the up-down lifting motion of the disturbance ring 50, and the disturbance ring 50 is in close contact with the inner wall of the treatment tank body 10, which can not only break the laminar flow state of the wastewater and the treatment agent, form a three-dimensional disturbance flow field, and avoid the phenomenon of insufficient reaction in the local area, but also can scrape off the reaction residues and impurities attached to the inner wall of the treatment tank body 10, prevent the scaling of the inner wall from affecting the treatment efficiency, and ensure the continuity and stability of the staged treatment process.

[0072] Relying on the linkage design of the disturbance ring 50 and the feeding tank 30, without additional independent feeding driving mechanism, the lifting motion of the disturbance ring 50 can synchronously trigger the feeding process, realize the mechanical linkage and cooperation of stirring, disturbance and feeding, which on the one hand simplifies the overall structure of the device, reduces the number of power sources, and reduces the equipment manufacturing cost, operation energy consumption and later operation and maintenance difficulty; on the other hand, it can accurately match the adding amount and timing of the treatment and purification raw materials according to the disturbance rhythm, avoid the secondary pollution caused by excessive treatment agent or the attenuation of treatment effect caused by insufficient addition, further optimize the reaction conditions of the staged treatment, and improve the stability of the overall treatment efficiency and treatment quality.

[0073] Specifically, the treatment cover plate 20 is provided with a servo drive motor 21, and the servo drive motor 21 is in transmission connection with the stirring shaft 11.

[0074] The stirring shaft 11 is provided with stirring blades 12, and the stirring blades 12 are arranged below the disturbance ring 50.

[0075] In this embodiment, through the transmission connection of the servo drive motor 21 and the stirring shaft 11, the characteristics of adjustable rotating speed, stable output torque and fast response speed of the servo drive motor 21 can be utilized to accurately control the rotating speed, starting and stopping time and rotating angle of the stirring shaft 11, solve the technical problems of uneven mixing of wastewater and treatment and purification raw materials and unstable reaction conditions caused by large rotating speed fluctuation and low transmission precision of the traditional driving mechanism, provide controllable and stable power support for the subsequent stirring of the stirring blades 12, the motion of the disturbance ring 50 and the feeding linkage process, and guarantee the consistency and reliability of the electronic grade hydrogen peroxide wastewater staged treatment process, which meets the strict requirements of electronic grade wastewater on treatment precision.

[0076] Specifically, the driving assembly 60 includes a lifting spiral 61, and the lifting spiral 61 is arranged on the outer wall of the stirring shaft 11.

[0077] The outer wall of the lifting spiral 61 is provided with a connecting ring 62, the connecting ring 62 is coaxially arranged with the disturbance ring 50, and a plurality of connecting rods 63 are uniformly arranged between the connecting ring 62 and the disturbance ring 50.

[0078] In this embodiment, the driving assembly 60 accurately converts the single rotary power of the stirring shaft 11 into the axial lifting power of the connecting ring 62 through the matching of the lifting screw 61 and the connecting ring 62, and then drives the disturbance ring 50 to realize the synchronous up-down lifting movement through the connecting rod 63, without the need for additional independent lifting driving mechanism, solving the technical problems of complex structure and poor coordination caused by the separation of stirring and disturbance power in traditional devices, realizing the integration and efficiency of power transmission, and providing core power support for the full mixing of wastewater and treatment and purification raw materials in the tank.

[0079] The connecting ring 62 and the disturbance ring 50 are coaxially arranged, and combined with multiple groups of uniformly distributed connecting rods 63, so that the power transmitted by the connecting ring 62 can uniformly act on each position of the disturbance ring 50 in the circumferential direction, avoiding the inclination, jamming or deviation of the disturbance ring 50 during movement, ensuring that the disturbance ring 50 always maintains stable contact with the inner wall of the treatment tank 10, and ensuring the consistency of the effect of scraping the adherents on the inner wall and disturbing the materials in the tank; at the same time, the uniformly distributed connecting rods 63 effectively disperse the stress during movement, improving the load capacity and fatigue resistance of the connecting structure of the driving assembly 60 and the disturbance ring 50, and prolonging the service life of the device.

[0080] During the movement of the multiple connecting rods 63 with the connecting ring 62 and the disturbance ring 50, the laminar state of the wastewater in the tank can be further broken, forming a multi-directional auxiliary disturbance flow field, which cooperates with the main disturbance of the disturbance ring 50 and the bottom stirring of the stirring blade 12, expands the disturbance coverage, and improves the contact frequency and contact area of the wastewater and the treatment and purification raw materials, effectively avoiding the problem of local material deposition or uneven mixing, and significantly strengthening the reaction sufficiency and purification efficiency of single-tank treatment.

[0081] Specifically, the connecting ring 62 is provided with a connecting hole 622, and a driving screw groove 621 is arranged in the connecting hole 622.

[0082] The stirring shaft 11 is arranged in the connecting hole 622, and the lifting screw 61 is matched with the driving screw groove 621.

[0083] In this embodiment, through the matching design of the driving screw groove 621 and the lifting screw 61, the rotary movement of the stirring shaft 11 is accurately converted into the axial lifting movement of the connecting ring 62 through the screw transmission principle. The transmission structure is closely matched, and the power transmission loss is small, solving the technical problems of poor movement coordination and low power conversion efficiency caused by traditional multiple power sources or complex transmission mechanisms, and ensuring that the rotary power of the stirring shaft 11 can be stably and efficiently converted into the lifting power required by the disturbance ring 50.

[0084] Specifically, the connecting rod 63 is provided with a reinforcing ring 70, and the reinforcing ring 70 is provided with a rotating impeller 71;

[0085] The reinforcing ring 70 is provided with a reinforcing plate 72, and the rotating impeller 71 is rotationally arranged on the reinforcing plate 72.

[0086] In this embodiment, the rotating impeller 71 rotationally arranged in the reinforcing ring 70 is self-rotated under the impact of the wastewater and the fluid of the treatment and purification raw materials in the tank when the connecting rod 63 moves up and down with the disturbance ring 50 and the connecting ring 62, forming a three-level cooperative disturbance system of bottom stirring of the stirring blade 12, composite disturbance of the disturbance ring 50, and self-adaptive rotating disturbance of the rotating impeller 71.

[0088] Specifically, two groups of treatment pipelines 22 are symmetrically arranged in the treatment tank body 10, and the two groups of treatment pipelines 22 are arranged on the treatment cover plate 20, respectively. The treatment pipeline 22 is provided with a treatment port 23, and the treatment pipeline 22 is connected with the bottom end of the treatment tank body 10.

[0089] The disturbance ring 50 is symmetrically provided with two groups of disturbance blocks 52, and the disturbance block 52 is provided with a disturbance hole 51.

[0090] The two groups of treatment pipelines 22 are arranged in the two groups of disturbance holes 51, respectively.

[0091] In this embodiment, the two groups of symmetrically arranged treatment pipelines 22 and the disturbance holes 51 form a bidirectional guiding structure, accurately constrain the movement trajectory of the disturbance ring 50, avoid the circumferential deviation, inclination or jamming phenomenon of the disturbance ring 50 during the lifting process, ensure that the disturbance ring 50 always moves smoothly along the axis direction of the treatment tank body 10, and keeps uniform contact with the inner wall of the tank body, guarantees the consistency of the effect of the disturbance ring 50 scraping the adherents on the tank wall and uniformly disturbing the materials in the tank; at the same time, the symmetric guiding structure disperses the radial load in the movement process of the disturbance ring 50, reduces the transmission loss of the driving assembly 60, and improves the movement reliability of the overall structure.

[0092] The processing pipeline 22 directs the processing medium into the tank through the processing port 23, and the distribution position thereof is accurately matched with the movement track of the disturbance ring 50 and the stirring blade 12, so that the processing medium can be quickly dispersed and mixed by the movement of the disturbance ring 50 and the stirring blade 12 as soon as it enters the tank, avoiding the problems of local enrichment or slow diffusion of the processing medium; at the same time, the symmetrically distributed processing pipeline 22 can realize uniform distribution of the processing medium in the tank, ensuring that the wastewater and the processing medium maintain balanced reaction concentration in the whole tank domain, improving the stability and consistency of the treatment effect, and adapting to the strict requirements of electronic-grade hydrogen peroxide wastewater on treatment precision.

[0093] Specifically, the top end of the feeding tank 30 is provided with a feeding pipeline 31, and the bottom end of the feeding tank 30 is provided with a discharging pipeline 36, which is arranged towards the inner cavity of the processing tank body 10.

[0094] The discharging pipeline 36 is provided with a liftable blocking plate 35.

[0095] In this embodiment, the discharging pipeline 36 is arranged towards the inner cavity of the processing tank body 10, which can directly direct the processing and purification raw materials in the feeding tank 30 to the core reaction area of the processing tank body 10, effectively avoiding the problems of overflow, splashing or misplacement of the raw materials during the feeding process, ensuring that the processing agent and the electronic-grade hydrogen peroxide wastewater are in rapid and accurate contact, improving the utilization rate of the raw materials, while avoiding waste of raw materials and pollution to the external environment of the device, and adapting to the strict requirements of electronic-grade wastewater treatment on feeding accuracy.

[0096] Specifically, the feeding tank 30 is provided with a support plate 32, and a support rod 33 is arranged between the support plate 32 and the inner wall of the feeding tank 30.

[0097] The blocking plate 35 is slidingly arranged in the discharging pipeline 36, and a support spring 34 is arranged between the blocking plate 35 and the support plate 32.

[0098] Specifically, the disturbance ring 50 is provided with a discharging rod 74, which is coaxially arranged with the discharging pipeline 36, so that the discharging rod 74 is lifted to contact the blocking plate 35, driving the blocking plate 35 to be lifted, so that the discharging pipeline 36 is in a free state for discharging.

[0099] The bottom end of the discharging rod 74 is provided with a fixed plate 73, which is connected with the reinforcing ring 70.

[0100] In this embodiment, through the coaxial design of the discharging rod 74 and the discharging pipeline 36, and the rigid connection of the fixed plate 73 and the reinforcing ring 70, the lifting movement of the disturbance ring 50 is directly converted into the feeding trigger power of the feeding tank 30, cooperating with the elastic reset action of the support spring 34, to form the lifting of the disturbance ring 50, the lifting of the blocking plate 35 by the discharging rod 74, and the start of feeding.

[0101] The self-adaptive linkage mechanism of the descending of the disturbance ring 50, the resetting of the supporting spring 34, the closing of the blocking plate 35, and the stopping of the feeding realizes the single power source integration and cooperation of the stirring, the disturbance, and the feeding, greatly simplifies the overall structure and the control logic of the device, and solves the technical problems of the complex structure, the poor coordination, and the high energy consumption caused by the separation of the feeding and the disturbance power in the traditional device.

[0102] The coaxial arrangement of the discharging rod 74 and the discharging pipeline 36 precisely restricts the movement track of the discharging rod 74, ensures that the discharging rod 74 always moves smoothly along the axial direction when the disturbance ring 50 rises and falls, and precisely aligns the blocking plate 35 to realize the lifting action, avoiding the linkage failure caused by the deviation, the jamming, or the misalignment. At the same time, the fixed plate 73 rigidly connects the discharging rod 74 and the reinforcing ring 70, so that the stress of the discharging rod 74 is evenly transmitted to the connecting rod 63 and the disturbance ring 50 through the reinforcing ring 70, avoiding the bending and deformation of the discharging rod 74 caused by the local stress concentration, ensuring the long-term stable operation of the linkage structure, and improving the reliability of the device in the continuous processing scene.

[0106] The servo drive motor 21 on the treatment cover plate 20 is started, and through the transmission connection with the stirring shaft 11, the rotation speed and the start-stop timing of the stirring shaft 11 are precisely controlled to provide stable power for the subsequent collaborative process;

[0107] S2. Single-tank three-stage collaborative disturbance treatment:

[0108] When the stirring shaft 11 rotates, the stirring blade 12 at the bottom thereof performs full-domain stirring on the wastewater and the preset raw materials in the tank, and the lifting spiral 61 on the outer wall of the stirring shaft 11 and the driving spiral groove 621 of the connecting ring 62 are adaptively transmitted to convert the rotary motion into the axial lifting motion of the connecting ring 62, and through a plurality of evenly distributed connecting rods 63, the disturbance ring 50 is driven to rise and fall along the two groups of symmetrically arranged treatment pipelines 22.

[0109] The disturbance ring 50 is in close contact with the inner wall of the treatment tank body 10, and scrapes off the reaction residues and scale attached to the inner wall during the lifting process, and breaks the laminar flow state to form a three-dimensional disturbance flow field in the whole tank;

[0110] And when the reinforcing ring 70 on the connecting rod 63 moves synchronously with the disturbance ring 50, the rotating impeller 71 inside it rotates autonomously under the impact of fluid, forming a three-level coordinated disturbance system of bottom stirring by the stirring blade 12, three-dimensional disturbance by the disturbance ring 50, and adaptive precise disturbance by the rotating impeller 71, ensuring that the wastewater and the treatment raw materials are fully mixed and reacted;

[0111] S3. Disturbance and feeding adaptive linkage:

[0112] During the upward movement of the disturbance ring 50, the discharge rod 74 rigidly connected with the reinforcing ring 70 through the fixed plate 73 is lifted synchronously along the axis, lifting the blocking plate 35 in the discharge pipeline 36 of the feeding tank 30, so that the treatment and purification raw materials are directed to fall into the core reaction zone along the discharge pipeline 36 towards the inner cavity of the tank body;

[0113] When the disturbance ring 50 descends, the blocking plate 35 closes the discharge pipeline 36 under the elastic resetting action of the supporting spring 34, stopping the feeding, and realizing the adaptive matching of the feeding action and the disturbance rhythm;

[0114] S4. Graded deep treatment and transfer:

[0115] After the first group of treatment tanks 10 completes the preset treatment duration, the transfer pump body 41 on the connecting pipeline 40 is started to transfer the pretreated wastewater to the next group of treatment tanks 10, and steps S2-S3 are repeated, so that the reaction path and contact time are prolonged through the series connection of multiple groups of treatment tanks 10, until the impurity content and pollutant concentration of the wastewater meet the standards, and the discharge or recycling process is performed.

[0116] Specifically, in step S2, the linkage logic of the three-level coordinated disturbance is that the rotation speed of the stirring blade 12 and the lifting frequency of the disturbance ring 50 are accurately synchronized by the servo drive motor 21, the autonomous rotation speed of the rotating impeller 71 is dynamically adapted to the lifting speed of the disturbance ring 50 and the fluid flow rate in the tank, and the three form a full-area disturbance effect without mixing blind area;

[0117] In step S3, the discharge rod 74 is coaxially arranged with the discharge pipeline 36, ensuring that the coaxial error of the opening and closing action of the blocking plate 35 is ≤0.5mm, and the feeding amount is positively correlated with the lifting frequency of the disturbance ring 50 for adaptive adjustment, avoiding secondary pollution caused by excessive treatment raw materials or treatment efficiency decay caused by insufficient addition;

[0118] In step S2, the treatment pipeline 22 directs the auxiliary treatment medium into the tank through the treatment port 23, and the direction of the treatment medium is arranged in the opposite direction of the lifting direction of the disturbance ring 50, which strengthens the mixing uniformity of the medium and the wastewater, and at the same time, the treatment pipeline 22 forms bidirectional guiding constraint to the movement track of the disturbance ring 50, ensuring that the contact pressure between the disturbance ring 50 and the inner wall of the treatment tank 10 is uniformly distributed.

[0119] While embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.

Unit Start-up and Raw Material Pre-setting: Electronic-grade hydrogen peroxide wastewater is introduced into the first treatment tank (10), and the raw materials for treatment and purification are supplemented through the feed pipe (31) at the top of the feed tank (30). After the raw materials are pre-loaded, the feed pipe (31) is closed. The servo drive motor (21) on the processing cover plate (20) is started, and through its transmission connection with the stirring shaft (11), the rotation speed and start-stop timing of the stirring shaft (11) are precisely controlled, providing stable power for subsequent collaborative processes; S2. Single-tank three-level coordinated disturbance handling: When the stirring shaft (11) rotates, the stirring blades (12) at its bottom stir the wastewater and pre-placed raw materials in the tank. At the same time, the lifting spiral (61) on the outer wall of the stirring shaft (11) and the driving spiral groove (621) of the connecting ring (62) are adapted to drive the rotational motion into the axial lifting motion of the connecting ring (62). Through multiple sets of evenly distributed connecting rods (63), the disturbance ring (50) is driven to move up and down in a directional manner along two sets of symmetrically arranged processing pipes (22). The disturbance ring (50) is in close contact with the inner wall of the treatment tank (10). During the lifting and lowering process, it scrapes off the reaction residue and scale attached to the inner wall, and at the same time breaks the laminar flow state to form a three-dimensional disturbance flow field in the entire tank area. Furthermore, when the reinforcing ring (70) on the connecting rod (63) moves synchronously with the disturbance ring (50), the rotating impeller (71) inside it rotates autonomously under the impact of the fluid, forming precise disturbance to the local vortex area and material deposition area, and finally forming a three-level synergistic disturbance system of bottom stirring by the stirring blade (12), three-dimensional disturbance by the disturbance ring (50), and adaptive precise disturbance by the rotating impeller (71), ensuring that the wastewater and the treatment raw materials are fully mixed and reacted; S3.

When the disturbance ring (50) descends, the blockage plate (35) closes the discharge pipe (36) under the elastic reset action of the support spring (34), stops feeding, and realizes the adaptive matching between the feeding action and the disturbance rhythm; S4. Graded Deep Processing and Transfer: After the first set of treatment tanks (10) completes the preset treatment time, the transfer pump (41) on the connecting pipeline (40) is started to transfer the pretreated wastewater to the next set of treatment tanks (10). Steps S2-S3 are repeated.
