Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and in particular to a deep purification device and process for organic wastewater based on the environmentally friendly production of glycine. Background Technology

[0002] Industrial glycine is a large-scale chemically synthesized aminoacetic acid with a purity of 98.5%-99% and relatively low impurity control standards. It is mainly used as a raw material for pesticides and is also applied in water treatment, electroplating, and feed industries. However, glycine production generates a large amount of wastewater, which requires wastewater treatment equipment for purification. The organic wastewater from glycine production has a complex composition, and conventional wastewater treatment processes are difficult to achieve stable compliance. It needs to undergo multiple steps, including sedimentation, bar filtration, aerobic and anaerobic treatment, and finally, deep treatment and deep filtration, to ensure complete purification of the wastewater.

[0003] However, in existing technologies, the deep treatment section generally adopts a continuous water intake and constant flow dosing operation mode throughout the entire process. During the production process, glycine wastewater flows continuously and at a constant speed through the dosing and mixing area of ​​the equipment. The system simultaneously and continuously adds quantitative flocculant purification agents. Theoretically, this can achieve full coverage of the wastewater body with agents, providing the basic conditions for subsequent flocculation, impurity removal, nitrogen removal, and phosphorus removal reactions. However, the equipment adopts an open, straight-through or semi-open structure, with the mixing area completely connected to the front water inlet chamber and the rear mixing chamber. There are no dedicated flow-limiting components, multi-stage turbulence buffer structures, or independent retention and pressure stabilization spaces. The overall water flow is uncontrolled and flows straight through. Under continuous operation, the glycine wastewater containing high salt, high impurities, and large water quality fluctuations always maintains a high-speed straight flow state, and the added agents are rapidly transported with the water flow. Rapid loss of water and chemicals results in extremely short contact, diffusion, and fusion time between the water and the chemicals. Furthermore, the intermittent discharge and batch production of glycine lead to frequent fluctuations in wastewater inflow, pollutant concentration, and water viscosity, making the operating conditions highly unstable. This easily leads to severe short-circuiting, localized flow deviation, and uneven cross-sectional velocity within open channels, disrupting the mixing rhythm between the chemicals and the wastewater, reducing the hydraulic mixing disturbance effect, and preventing the chemicals from fully diffusing, blending, and mixing with the complex glycine wastewater. The distribution of chemicals in the water is extremely unbalanced, frequently resulting in excessively high concentrations of chemicals in localized areas and significant waste. Large amounts of wastewater that have not undergone sufficient mixing or effective pretreatment flow directly and rapidly out of the mixing area without any pressure stabilization, buffering, or secondary mixing treatment, entering the next deep filtration stage, severely impacting the purification effect. Summary of the Invention

[0004] The purpose of this invention is to provide a deep purification device and process for organic wastewater based on the environmentally friendly production of glycine, thereby solving the problem of insufficient deep mixing treatment of wastewater.

[0005] This invention proposes a deep purification device for organic wastewater produced using glycine in an environmentally friendly manner. The device includes a purification tank, multiple mixing pipes arranged at equal angles and fixedly connected inside the purification tank, a stirrer rotatably connected inside the mixing pipes, a manifold fixedly connected to the multiple mixing pipes, a connecting pipe connecting the manifold and the mixing pipes, an upper valve and a side valve located inside the connecting pipe, a camshaft rotatably connected inside the manifold, a diverter plate rotatably connected inside the purification tank, a servo motor and a drive motor located inside the purification tank, and a driver fixedly connected outside the purification tank. The manifold is located below the mixing pipes, and the diverter plate is located at one end of the mixing pipes. When the camshaft rotates intermittently, the upper valve and the side valve enable communication between the manifold and different mixing pipes. When the diverter plate rotates intermittently, one end of each mixing pipe is intermittently opened.

[0006] Furthermore, the connecting pipe is divided into a vertical pipe and a horizontal pipe. The vertical pipe is fixedly connected to the top of the manifold. There are two horizontal pipes, which are fixedly connected to both sides of the manifold. The upper valve is located inside the vertical pipe, and the side valve is located inside the horizontal pipe, and the two are of equal number. The bottom end of the manifold is connected to an outlet pipe.

[0007] Furthermore, the distributor plate has a circular slot. The distributor plate rotates counterclockwise and its circular slot intermittently communicates with different mixing pipes. When the circular slot communicates with one of the mixing pipes, only the next mixing pipe to communicate with the circular slot communicates with the manifold. When the circular slot communicates with the mixing pipe, the mixing pipe and the manifold do not communicate.

[0008] Furthermore, the upper valve component includes a circular shaft that is vertically slidably connected inside the vertical pipe, a first ball that is fixedly connected to the bottom end of the circular shaft, a semi-circular sleeve that is fixedly connected to the top end of the circular shaft, and a return spring connected between the circular shaft and the vertical pipe, wherein the semi-circular sleeve is located inside the corresponding mixing pipe.

[0009] Furthermore, the side valve component includes a horizontal shaft that is horizontally slidably connected inside the horizontal tube, a guide sleeve that is fixedly connected to the horizontal shaft, a sub-sphere that is fixedly connected to one end of the horizontal shaft, a return spring that is connected between the horizontal shaft and the horizontal tube, a vertical rod that is vertically slidably connected inside the mixing tube, and a circular sealing sleeve that is fixedly connected to the top of the vertical rod, the circular sealing sleeve being located inside the corresponding mixing tube.

[0010] Furthermore, the guide sleeve has an inclined slot, the top end of the vertical rod is located inside the inclined slot, the top end of the inclined slot gradually slopes downward to the bottom end, the top end of the inclined slot is located near the camshaft relative to the bottom end, and when the return spring is not deformed, the bottom end of the vertical rod is located at the bottom end of the inclined slot.

[0011] Furthermore, the agitator is provided with multiple liquid pipes on its exterior, and stirring blades are provided on the liquid pipes. A partition plate is slidably connected inside the stirring blades. A trigger spring is connected between the partition plate and the liquid pipes. Microholes are opened on the liquid pipes. The interiors of the liquid pipes and the agitator are hollow and interconnected. A feed port is provided at the end of the agitator away from the distribution plate.

[0012] Furthermore, the purification chamber is internally fixedly connected with a partition and a flow guide plate, the flow distribution plate is located between the partition and the flow guide plate, the top of the flow guide plate is provided with a flow guide hole, and the bottom of the flow guide plate is provided with an inclined plate.

[0013] Furthermore, each of the aforementioned agitators is fixedly connected to the output end of the driver, the output end of the servo motor is fixedly connected to the distributor plate, the output end of the drive motor is fixedly connected to the camshaft, and the servo motor and the drive motor are electrically connected.

[0014] Another aspect of the present invention provides: a deep purification process for organic wastewater produced in an environmentally friendly manner based on glycine, which is applied to a deep purification device for organic wastewater produced in an environmentally friendly manner based on glycine, comprising the following steps:

[0015] Step 1: First, use pretreatment equipment to intercept large debris using a screen, and then use a sedimentation process to separate suspended impurities, thus initially reducing the pollutant content in the water.

[0016] Step 2: The pretreated wastewater is fed into the purification tank and then sequentially into the anaerobic and aerobic reaction units, where microorganisms decompose organic pollutants.

[0017] Step 3: Subsequently, the wastewater passes through the diversion plate and enters the interior of the mixing tube to form an independent space. By driving the agitator to rotate, the reagent inside the agitator enters the interior of the mixing tube through centrifugal force. At the same time, the agitator stirs the water to complete the mixing reaction and carry out deep purification.

[0018] Step 4: Input the deeply treated wastewater into the horizontal purifier for deep filtration to remove residual pollutants and achieve wastewater purification and discharge in compliance with standards.

[0019] The beneficial effects of this invention are:

[0020] 1. Through the coordinated arrangement of mixing pipes at equal angles, built-in agitator, and centrifugal spraying structure, wastewater is evenly distributed to each independent mixing pipe cavity. With the intermittent rotation of the diversion plate driven by a servo motor to control water flow, the bottom pipe of a single mixing pipe is completely sealed when water enters, allowing the wastewater to achieve stable pressure retention within the cavity, ensuring sufficient flocculation reaction time, and preventing problems such as wastewater short-flow and incomplete reaction. At the same time, the hollow interior of the agitator connects to the feed interface, and with the adaptive micropores, partition plate, and trigger spring structure, it can automatically release the drug by relying on the centrifugal force of the agitation rotation, spraying the agent only during the agitation operation, avoiding premature leakage and waste of the agent.

[0021] 2. By coordinating the flow distribution plate, camshaft, and multiple sets of independent connecting pipes, a staggered sequential operation system is constructed, effectively solving the problems of turbulent water flow, cross-contamination within the chambers, and unstable operating conditions in traditional wastewater treatment equipment. The flow distribution plate rotates counterclockwise intermittently, sequentially connecting to each mixing pipe through the circular slot to complete the water intake, ensuring uniform and regular water flow. At the same time, the camshaft, in conjunction with the upper and side valves, controls the flow, realizing a staggered working logic of sealing and maintaining pressure in the inlet chamber and opening the outlet chamber in advance. Each mixing pipe has a clear division of labor and does not interfere with each other, with no water flow pulses or operational interruptions, significantly improving the overall operational stability and wastewater treatment efficiency of the equipment.

[0022] 3. The camshaft is driven to rotate intermittently by the drive motor, which squeezes the first and second balls, thereby driving the upper valve inside the vertical tube and the side valve inside the horizontal tube to open and close in an orderly manner. With the help of the return spring and reset spring, the components are automatically reset. The vertical and side flow paths can be flexibly switched to control the on and off state of each mixing tube. Relying on the timing valve control logic, the chamber is alternately filled with water, reacted, and discharged. The entire process is completed by the water body's own weight to complete the water flow and discharge. No electric booster is required for water supply. It is suitable for long-term continuous purification of glycine wastewater. Attached Figure Description

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1, refer to Figures 1-10 This is the first embodiment of the present invention, which provides a deep purification device for organic wastewater produced in an environmentally friendly manner based on glycine. The device includes a purification tank 1, multiple mixing pipes 2 arranged at equal angles and fixedly connected inside the purification tank 1, a stirrer 3 rotatably connected inside the mixing pipes 2, a manifold 4 fixedly connected to the multiple mixing pipes 2, a connecting pipe 5 connecting the manifold 4 and the mixing pipes 2, an upper valve 6 and a side valve 7 disposed inside the connecting pipe 5, a camshaft 8 rotatably connected inside the manifold 4, a diverter 9 rotatably connected inside the purification tank 1, a servo motor 10 and a drive motor 11 disposed inside the purification tank 1, and a driver 12 fixedly connected outside the purification tank 1. The manifold 4 is located below the mixing pipes 2, and the diverter 9 is located at one end of the mixing pipes 2. When the camshaft 8 rotates intermittently, the upper valve 6 and the side valve 7 allow the manifold 4 to communicate with different mixing pipes 2. When the diverter 9 rotates intermittently, one end of each mixing pipe 2 is intermittently opened.

[0037] Specifically, multiple mixing pipes 2 are evenly and uniformly fixed inside the purification tank 1 at equal angles. This allows the wastewater entering the equipment to be evenly distributed into each independent chamber, achieving zoned wastewater treatment and replacing the traditional single-channel centralized treatment mode. Structurally, this avoids the problems of concentrated water flow and uneven flow velocity. At the same time, multiple sets of mixing pipes 2 can work with subsequent flow control components to achieve alternating start and stop, and intermittent operation. The working chamber can be dynamically switched according to the influent conditions, always maintaining a stable water flow state inside each pipe. This provides an independent retention buffer space for the diffusion, mixing, and reaction of wastewater and flocculants, ensuring that each batch of wastewater has sufficient reaction time. Meanwhile, a stirrer 3 is correspondingly rotatably installed inside each mixing pipe 2. When mixing pipe 2 is in a closed, stagnant state, agitator 3 operates continuously, actively breaking the static laminar flow of the wastewater and creating a high-intensity hydraulic disturbance within the cavity. This forces the added reagent to rapidly diffuse and thoroughly mix with the high-impurity, high-viscosity glycine wastewater, significantly improving the uniformity of contact between the reagent and the wastewater. This prevents localized accumulation or gaps in reagent distribution, allowing the reagent to fully flocculate with impurities and nitrogen and phosphorus pollutants in the wastewater, effectively improving the pretreatment and purification quality of the wastewater. Manifold 4 is fixedly installed below multiple sets of mixing pipes 2 and connected to each mixing pipe 2 via multiple corresponding connecting pipes 5, forming a centralized wastewater collection and pressure-stabilized transport channel system. As an independent outlet channel for a single mixing pipe 2, it enables independent control of the opening and closing of a single chamber, effectively isolating water flow interference between different mixing pipes 2, avoiding the mixing of wastewater from different reaction stages and with different water quality concentrations, and ensuring the independence and integrity of the single-chamber reaction. The manifold 4 can collect, stabilize, and buffer the wastewater from each mixing pipe 2 after the mixing reaction, balancing the effluent flow rate and water quality, ensuring stable influent conditions for the downstream deep filtration process, and achieving orderly connection of the entire process flow. The camshaft 8 can rotate intermittently, synchronously driving the upper valve 6 and side valve 7 inside each connecting pipe 5 to open and close in an orderly and alternating manner during operation, thereby controlling the connection status between the manifold 4 and different mixing pipes 2. The time-sequential flow control function of the structure allows some mixing pipes 2 to be in a closed pressure-stabilized reaction state, while others are in an outlet and venting state, operating alternately in a cycle. This ensures that the wastewater has sufficient time for reagent reaction and allows the equipment to operate continuously without interruption, balancing treatment efficiency and purification effect. Specifically, by combining multiple sets of independent mixing pipes 2 for zoned operation, relying on the camshaft 8 to link the upper valve 6 and the side valve 7, and cooperating with the diverter plate 9, the entire process achieves intermittent and time-sequential flow control. Combined with the active turbulence mixing of the agitator 3, and the intelligent control of the servo motor 10, drive motor 11 and driver 12, a treatment process of zoned water inlet - closed pressure stabilization - active mixing - full reaction - alternating effluent discharge is formed.

[0038] Reference Figures 1-4The connecting pipe 5 is divided into a vertical pipe 51 and a horizontal pipe 52. The vertical pipe 51 is fixedly connected to the top of the manifold 4. There are two horizontal pipes 52, which are fixedly connected to both sides of the manifold 4 respectively. The upper valve 6 is located inside the vertical pipe 51, and the side valve 7 is located inside the horizontal pipe 52 and the two are the same number. The bottom end of the manifold 4 is connected to the outlet pipe 41.

[0039] Specifically, the connecting pipe 5 is divided into two parts: a vertical pipe 51 and a horizontal pipe 52. The vertical pipe 51 and horizontal pipe 52 have the same function but differ in shape, length, and position, forming a controllable communication channel between the mixing pipe 2 and the manifold 4. The vertical pipe 51 is vertically arranged, with its top end fixedly connected to the top surface of the manifold 4, forming the main vertical flow path. Two horizontal pipes 52 are symmetrically arranged, fixedly connected to the left and right sides of the manifold 4, forming lateral auxiliary flow channels. Through the three-dimensional pipeline layout of the vertical pipe 51 and the two horizontal pipes 52, a multi-directional, switchable fluid communication structure is formed between the manifold 4 and the upper mixing pipes 2. The upper valve 6 is correspondingly installed in the internal cavity of the vertical pipe 51, independently controlling the on / off state of the vertical pipeline and realizing the control of the vertical water flow channel. The side valves 7 are correspondingly installed inside the two horizontal pipes 52, with each side valve 7 corresponding to and matched with one of the horizontal pipes 52. The opening and closing states of the two transverse flow channels can be controlled independently. Through the partitioned and split valve control layout of the upper valve 6 and the side valve 7, the vertical pipe 51 and the horizontal pipe 52 form an independent yet coordinated controllable flow channel structure. According to the equipment operation sequence requirements, the vertical passage, the lateral passage or different flow combinations can be selectively opened to achieve flexible adjustment of the pipeline flow cross section, water flow direction and flow rate. The bottom center of the manifold 4 is fixedly connected to the outlet pipe 41, which serves as the water outlet of the entire pipeline manifold system. During the operation of the equipment, the wastewater that has completed the reagent mixing reaction inside each mixing pipe 2 can be controlled to flow into the manifold 4 through the vertical pipe 51 or the horizontal pipe 52. After being stabilized and buffered and evenly collected inside the manifold 4, it is uniformly output from the bottom outlet pipe 41, ensuring that the water flow is continuous, uniform and without pulse fluctuations, and improving the stability and orderliness of the overall purification process.

[0040] Reference Figures 1-5 The distributor plate 9 has a circular slot 91. The distributor plate 9 rotates counterclockwise and its circular slot 91 intermittently communicates with different mixing pipes 2. When the circular slot 91 communicates with one of the mixing pipes 2, only the next mixing pipe 2 that will communicate with the circular slot 91 communicates with the manifold 4. When the circular slot 91 communicates with the mixing pipe 2, the mixing pipe 2 and the manifold 4 do not communicate with each other.

[0041] Specifically, the diversion plate 9 operates by intermittent counterclockwise rotation. Through this circular rotation, the circular slot 91 allows for sequential, intermittent, and circumferentially arranged interconnection between the ports of different mixing pipes 2, thus completing the alternating water intake operation of each mixing pipe 2. Based on the structural feature of multiple mixing pipes 2 arranged at equal angles, combined with the constant counterclockwise intermittent rotation of the diversion plate 9, multiple sets of mixing pipes 2 can be connected to the water intake process in an orderly and alternating manner, ensuring the continuity and regularity of the equipment's water intake operation and avoiding the problems of turbulent flow and uneven diversion caused by simultaneous water intake from multiple pipes. Furthermore, when the circular slot 91 is aligned and interconnected with the upper port of one of the mixing pipes 2 at any given time, achieving water intake conduction, the mixing pipe 2 in the water intake state remains completely blocked from interconnection with the bottom manifold 4. This structural design ensures that the mixing pipes 2 form a closed cavity structure during the water intake stage, preventing wastewater from flowing directly downwards after entering the cavity, allowing the wastewater to remain stably within the cavity. Inside the mixing pipe 2, the internal agitator 3 ensures thorough mixing of the reagents, completely eliminating the problems of direct wastewater outflow and insufficient reaction time during the inlet stage. This provides sufficient pressure stabilization and retention time for the wastewater purification reaction. Simultaneously, under the current operating condition of the mixing pipe 2 corresponding to the circular slot 91, only the next mixing pipe 2 to be aligned and interconnected with the circular slot 91 in the circumferential arrangement of the equipment is connected to the manifold 4 in advance. This differentiated on / off linkage design allows the wastewater from the mixing pipe 2 that has completed the inlet, agitation, and flocculation reaction in the previous round to flow into the manifold 4 through the connecting pipe 5 and be stably discharged through the outlet pipe 41 in advance, realizing the orderly discharge of pretreated wastewater. Through this alternating staggered on / off sequence structure, the equipment always maintains a cyclical working state of single-pipe inlet reaction, next-pipe pressure stabilization and water discharge, and the remaining chambers in closed standby. Each mixing pipe 2 has a clear division of labor and does not interfere with each other, improving the overall treatment efficiency and purification uniformity of the equipment.

[0042] Reference Figures 1-8 The upper valve 6 includes a round shaft 61 that is vertically slidably connected inside the vertical tube 51, a first ball 62 that is fixedly connected to the bottom end of the round shaft 61, a semi-circular sleeve 63 that is fixedly connected to the top end of the round shaft 61, and a return spring 64 that is connected between the round shaft 61 and the vertical tube 51. The semi-circular sleeve 63 is located inside the corresponding mixing tube 2.

[0043] Reference Figures 1-3 The side valve component 7 includes a horizontal shaft 71 that is horizontally slidably connected inside the horizontal tube 52, a guide sleeve 72 that is fixedly connected to the horizontal shaft 71, a sub-sphere 73 that is fixedly connected to one end of the horizontal shaft 71, a return spring 74 that is connected between the horizontal shaft 71 and the horizontal tube 52, a vertical rod 75 that is vertically slidably connected inside the mixing tube 2, and a circular sealing sleeve 76 that is fixedly connected to the top end of the vertical rod 75. The circular sealing sleeve 76 is located inside the corresponding mixing tube 2.

[0044] The guide sleeve 72 has an inclined slot 721. The top end of the vertical rod 75 is located inside the inclined slot 721. The top end of the inclined slot 721 gradually slopes downward to the bottom end. The top end of the inclined slot 721 is located near the camshaft 8 relative to the bottom end. When the return spring 74 is not deformed, the bottom end of the vertical rod 75 is located at the bottom end of the inclined slot 721.

[0045] In this process, the camshaft 8 intermittently and sequentially squeezes the first ball 62 and the second ball 73. When the camshaft 61 is pressed, it moves upward and compresses the return spring 64. When the camshaft 61 moves downward, it drives the semi-circular sleeve 63 to move synchronously and open the top of the vertical tube 51, so that the top of the corresponding mixing tube 2 and the manifold 4 are connected. When the horizontal shaft 71 is pressed, it moves laterally and compresses the return spring 74. When the horizontal shaft 71 moves, it drives the guide sleeve 72 to move synchronously, so that the guide sleeve 72 pushes the vertical rod 75 and the circular sealing sleeve 76 to move upward. At this time, the top of the corresponding mixing tube 2 and the manifold 4 are connected.

[0046] Specifically, the camshaft 8 can achieve intermittent rotational motion and sequentially and orderly squeeze the first ball 62 and the second ball 73, respectively driving the upper valve 6 and the side valve 7 to complete the corresponding opening and closing actions, realizing the switching of pipeline passage. When the camshaft 8 squeezes the first ball 62, the first ball 62 drives the round shaft 61 to slide vertically upward along the vertical pipe 51, and simultaneously compresses the return spring 64 to store force and deform. As the round shaft 61 moves upward, the semi-circular sleeve 63 at the top rises synchronously, releasing the sealing and limiting of the top port of the vertical pipe 51, so that the vertical pipe 51 is fully open. The bottom cavity of the corresponding mixing pipe 2 and the top of the manifold 4 are interconnected through the vertical pipe 51, completing the vertical flow of wastewater. When the camshaft 8 disengages from the first ball 62, the return spring 64 releases elastic potential energy, pushing the round shaft 61, the first ball 62 and the semi-circular sleeve 63 to quickly reset, re-seal the port of the vertical pipe 51, and cut off the vertical flow passage.

[0047] Additionally, when the camshaft 8 rotates and compresses the secondary ball 73, the secondary ball 73 is forced to slide the horizontal shaft 71 horizontally inward along the horizontal tube 52, simultaneously compressing the return spring 74 to complete the storage of force. During the sliding process, the horizontal shaft 71 drives the guide sleeve 72 to move laterally inward in sync. Relying on the inclined structure of the inclined slot 721, as the guide sleeve 72 moves inward, since the inclined slot 721 is connected to the bottom end of the vertical rod 75, it continuously pushes the vertical rod 75 to slide vertically upward, thereby driving the circular sealing sleeve 76 at the top of the vertical rod 75 to move upward in sync. The blockage restriction on the corresponding pipe port is lifted, allowing the corresponding mixing pipe 2 and the manifold 4 to be laterally interconnected through the horizontal pipe 52, opening the lateral wastewater flow channel. When the camshaft 8 and the sub-sphere 73 are no longer in contact, the return spring 74 rebounds and resets, pushing the horizontal shaft 71 and the guide sleeve 72 back to reset. The inclined slot 721 returns to its initial position along with the guide sleeve 72, and the vertical rod 75 falls back along the trajectory of the inclined slot 721. The circular seal 76 descends and resets simultaneously, re-blocking the lateral passage and cutting off the lateral water flow channel.

[0048] Reference Figures 2-7 The stirrer 3 has multiple liquid pipes 31 on its exterior. Stirring blades 32 are installed on the liquid pipes 31. A separator plate 33 is slidably connected inside the stirring blades 32. A trigger spring 34 is connected between the separator plate 33 and the liquid pipes 31. Microholes 311 are opened on the liquid pipes 31. The interiors of the liquid pipes 31 and the stirrer 3 are hollow and interconnected. A feed port 301 is provided at the end of the stirrer 3 away from the distribution plate 9. The trigger spring 34 is compressed by centrifugal force, which drives the separator plate 33 to move. The separator plate 33 passes over the microholes 311, allowing the liquid in the liquid pipes 31 and the interior of the stirrer 3 to pass through the microholes 311.

[0049] Specifically, each liquid pipe 31 is interconnected with the hollow cavity inside the main body of the agitator 3, forming a fully connected liquid delivery channel. The stirring blade 32 rotates synchronously with the liquid pipe 31 and the agitator 3, responsible for stirring the wastewater inside the mixing pipe 2, breaking the laminar flow state of the water, and creating a turbulent mixing effect. Under normal conditions, the trigger spring 34 can stably push the separator plate 33 without external force, so that the separator plate 33 always seals and covers the micropores 311 of the liquid pipe 31, achieving a tight seal of the micropores 311, effectively preventing liquid leakage and premature outflow when the equipment is idle or running at low speed, and preventing problems such as liquid waste and uneven concentration of local agents. The external flocculant can be continuously fed into the hollow cavity inside the agitator 3 through the feed interface 301, providing a stable liquid supply source for subsequent centrifugal spraying operations. When the equipment is working, the agitator 3 rotates at high speed to generate Centrifugal force causes the liquid pipe 31 and the stirring blade 32 to rotate synchronously at high speed. Under the action of centrifugal force, the separator 33 generates an outward sliding driving force, continuously compressing the trigger spring 34 to store and deform its elasticity, thereby driving the separator 33 to slide outward along the internal cavity of the stirring blade 32. When the speed of the stirrer 3 reaches the set working condition threshold, the sliding stroke of the separator 33 passes the arrangement position of the micro-holes 311, releasing the blockage of the micro-holes 311, so that the liquid stored in the stirrer 3 and the liquid pipe 31 can be diffused and sprayed outward through the micro-holes 311. The higher the stirring speed and the greater the intensity of wastewater disturbance, the stronger the centrifugal force. The opening degree of the micro-holes 311 is synchronously adapted and adjusted with the amount of liquid sprayed. At the same time, the liquid is sprayed out through the high-speed rotating stirring blade 32 and the micro-holes 311 of the liquid pipe 31, and can be directly injected into the interior of the wastewater body. Accompanied by the stirring disturbance, it diffuses and mixes in all directions, ensuring effective deep treatment of wastewater.

[0050] Reference Figures 2-10The purification tank 1 is internally fixedly connected with a partition 101 and a guide plate 102 to form a compartment, allowing wastewater to enter the area. The diversion plate 9 is located between the partition 101 and the guide plate 102, ensuring that the inlet water diversion process is concentrated and orderly, effectively avoiding the problems of wastewater turbulence, overflow, and uneven diversion. It can perform initial rectification of the inlet water flow, breaking up the inlet water pulse and water flow turbulence, and preventing high-pressure direct water flow from directly impacting the diversion plate 9. It effectively protects the stability of the intermittent rotation of the diversion plate 9, ensuring that the wastewater entering the compartment has a uniform flow rate and a stable flow state. The top of the guide plate 102 is provided with a guide hole 100, allowing wastewater to enter the compartment from the top of the guide plate 102. The bottom of the guide plate 102 is provided with an inclined plate 110 for guiding the flow, so that the water flow is always concentrated and transported towards the diversion station.

[0051] Reference Figures 1-10 Multiple stirrers 3 are fixedly connected to the output end of the driver 12, the output end of the servo motor 10 is fixedly connected to the distributor plate 9, the output end of the drive motor 11 is fixedly connected to the camshaft 8, and the servo motor 10 and the drive motor 11 are electrically connected so that they can start synchronously and intermittently to generate drive.

[0052] Specifically, the angle at which the servo motor 10 drives the diverter plate 9 to rotate each time is equal to the angle of the multiple mixing pipes 2. The angle at which the drive motor 11 drives the camshaft 8 to rotate each time needs to match the position of the upper valve 6 and the side valve 7. In order to ensure that the water flow can automatically flow down from top to bottom, the present invention does not set up a pump body. When the camshaft 8 needs to switch between the working positions of the upper valve 6 and the side valve 7, the controller controls the drive motor 11 to drive the camshaft 8 to rotate 90 degrees in a single rotation, which can complete the switching between the vertical valve control passage and the side valve control passage. When the camshaft 8 needs to switch between the working positions of the two side valves 7, the controller controls the drive motor 11 to drive the camshaft 8 to rotate 180 degrees in a single rotation, realizing the alternating opening and closing of the two side flow passages.

[0053] Understandably, the TPC8-8TD programmable PLC controller can be used as the core of the equipment's automated timing control. This controller is an industrial-grade dedicated motion control module with multi-axis pulse output, angle positioning, timing linkage, and delay control functions. It is fully compatible with the dual-motor collaborative control requirements of this wastewater purification equipment. The TPC8-8TD controller is equipped with eight inputs and supports four independent pulse outputs. It can simultaneously and stably drive two sets of power actuators, namely servo motor 10 and drive motor 11. It has strong anti-interference capabilities and is suitable for complex industrial conditions such as humid and dusty water treatment. The controller can directly compile and store exclusive angle parameters and switching programs. It integrates angle preset, timing linkage, and working condition adaptation control functions. It can match the water inlet timing of the diversion plate 9 and the pipeline on / off timing of the camshaft 8 in real time, strictly ensuring the timing correspondence of each process, including water distribution, cavity pressure stabilization, chemical mixing, and pipeline water discharge.

[0054] The working principle of this invention is as follows: Organic wastewater flows through the guide hole 100 at the top of the guide plate 102 into the inlet compartment formed by the baffle 101 and the guide plate 102. The inclined plate 110 guides the water flow, eliminating turbulent impact and smoothly delivering it to the area of ​​the diversion plate 9. The servo motor 10 and the drive motor 11 operate synchronously and intermittently. The servo motor 10 drives the diversion plate 9 to rotate counterclockwise and intermittently. The circular slots 91 are sequentially aligned and connected to each mixing pipe 2, realizing the timed and zoned injection of wastewater into the independent mixing pipe 2 cavity. The mixing pipe 2 connected to the inlet is simultaneously blocked from the manifold 4 pipeline, and the wastewater... Water is trapped inside the chamber, preventing leakage and ensuring reaction time. The driver 12 drives the agitators 3 in each mixing tube 2 to rotate synchronously. The flocculant is introduced into the hollow cavity of the agitator 3 through the feed inlet 301. Under normal conditions, the separator 33, aided by the trigger spring 34, seals the micropores 311, preventing premature leakage. The high-speed rotation of the agitator 3 generates centrifugal force, pushing the separator 33 to compress the trigger spring 34 and slide outwards, disengaging from the micropore 311 seal. The flocculant is then dispersed through the micropores 311 and sprayed into the wastewater. The stirring blades 32 simultaneously agitate the water, breaking the laminar flow and promoting... The reagent and wastewater are fully mixed, allowing impurities and nitrogen and phosphorus pollutants in the water to undergo a highly efficient flocculation reaction. The drive motor 11 drives the camshaft 8 to rotate intermittently, sequentially squeezing the first ball 62 of the upper valve 6 and the second ball 73 of the side valve 7, thus switching the pipeline on and off. When the camshaft 8 pushes the first ball 62, the shaft 61 moves upward to compress the return spring 64, the semi-circular sleeve 63 disengages from the blockage, the vertical pipe 51 opens, and the mixing pipe 2 and the manifold 4 are vertically connected. After the squeezing is released, the spring rebounds, and the vertical pipeline immediately closes. When the camshaft 8 squeezes the second ball 73, the horizontal shaft 71 moves laterally. The dynamic compression reset spring 74 and guide sleeve 72 follow the inclined slot 721 to lift the vertical rod 75, the circular sealing sleeve 76 releases the blockage, the horizontal pipe 52 is opened in the lateral passage, the component is reset after the external force disappears, the lateral pipeline is closed, the equipment operates according to the staggered timing logic, when the circular slot 91 corresponds to the mixing pipe 2 in the water inlet reaction condition, only the next water inlet mixing pipe 2 is connected to the manifold 4 in advance, the wastewater that has completed the flocculation reaction is connected to the manifold 4 through the connecting pipe 5, and after pressure stabilization and buffering, it is stably discharged from the outlet pipe 41, continuously completing the deep purification treatment of glycine organic wastewater in the partition.

[0055] Example 2, refer to Figures 1-10 This is the second embodiment of the present invention, a deep purification process for organic wastewater based on the environmentally friendly production of glycine, which is applied to a deep purification device for organic wastewater based on the environmentally friendly production of glycine, including the following steps:

[0056] Step 1: First, use pretreatment equipment to intercept large debris using a screen, and then use a sedimentation process to separate suspended impurities, thus initially reducing the pollutant content in the water.

[0057] Step 2: Input the pretreated wastewater into the purification tank 1 and send it into the anaerobic and aerobic reaction units in sequence, where microorganisms decompose organic pollutants.

[0058] Step 3: Subsequently, the wastewater passes through the diversion plate 9 and enters the interior of the mixing pipe 2 to form an independent space. By driving the agitator 3 to rotate, the reagent inside the agitator 3 enters the interior of the mixing pipe 2 through centrifugal force. At the same time, the agitator 3 stirs the water to complete the mixing reaction and carry out deep purification.

[0059] Step 4: Input the deeply treated wastewater into the horizontal purifier for deep filtration to remove residual pollutants and achieve wastewater purification and discharge in compliance with standards.
