Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a wastewater treatment device and a treatment method for the production process of choline chloride. Background Art

[0002] As an important organic compound, choline chloride has a wide range of applications in the fields of food, medicine, and chemical industry. However, a large amount of wastewater is generated during the production process of choline chloride, and this wastewater contains high concentrations of organic matter and chlorides. If directly discharged into the environment, it will have a serious impact on the surrounding ecological environment. Therefore, developing an efficient wastewater treatment device is of great significance for the sustainable development of choline chloride production and environmental protection.

[0003] For example, in the patent document with the prior art publication number CN222138865U, this patent document discloses a desizing wastewater treatment tank, including a wastewater treatment tank. A number of air flow pipes are evenly arranged at the bottom of the wastewater treatment tank. A number of aeration discs are provided on the air flow pipes. The air flow pipes converge at the main air pipe, and the main air pipe is communicated with an external air inlet pipe. An air flow control box for adjusting the air flow size in the air inlet pipe is provided on the air inlet pipe. One side of the air flow control box is rotatably connected to a rotating rod. The rotation angle of the rotating rod corresponds to the air flow size in the air inlet pipe. A rotation adjustment structure for adjusting the rotation angle of the rotating rod is provided on the rotating rod. The rotation angle of the rotating rod rotates with the change of the liquid level in the wastewater treatment tank. A drain port for facilitating drainage is provided on the wastewater treatment tank; this treatment tank can change the aeration size according to the change of the liquid level in the tank, improving the use effect.

[0004] Although the above-mentioned prior art can flexibly adjust the aeration volume according to the real-time changes of the liquid level in the sewage treatment tank by cleverly setting up the airflow control box, this design has enhanced the treatment effect of wastewater to a certain extent, especially in controlling the dissolved oxygen content and promoting microbial activity. However, in the actual application scenarios of industrial wastewater or domestic sewage treatment, the effect of simply relying on aeration operations to purify water quality is often inadequate. When treating wastewater containing a large amount of suspended matter, grease, and difficult-to-degrade organic matter, simply increasing the oxygen content through aeration cannot effectively remove these pollutants. Suspended matter may be temporarily dispersed due to aeration, but it is difficult to achieve true sedimentation and removal; grease may be attached to it due to the tiny bubbles formed by aeration, which increases the difficulty of subsequent treatment. In addition, more importantly, this technology usually requires the sewage that has been treated with preliminary aeration to be transferred to other professional treatment equipment (such as coagulation sedimentation tanks, bioreactors or membrane filtration devices) for secondary or even multiple treatments to meet the emission standards. This transportation process not only increases additional energy consumption and transportation costs, but may also reduce the overall treatment efficiency due to secondary pollution or treatment delays during the transportation process. To this end, the present application proposes a wastewater treatment device and a treatment method for use in the choline chloride production process. Summary of the invention

[0005] The object of the present invention is to provide a wastewater treatment device and a treatment method for the production process of choline chloride to solve the problems raised in the above background technology.

[0007] The grille is fixedly connected to the inside of the inner tank body and is used to intercept fine particles in the wastewater. The top of the rotating tube extends to the top of the grille and is provided with a cross bar. The outer surface of the cross bar is provided with a scraping assembly for cleaning the grille.

[0008] A liquid storage shell is sleeved on the outer surface of the rotating tube and stores coagulant inside. The outer surface of the rotating tube is evenly connected with a plurality of bronchial tubes for exhausting gas, and the outer surface of the liquid storage shell is provided with a liquid discharge component for conveying the coagulant;

[0009] The culture rack is filled at the inner bottom of the treatment tank and is made of porous material to cultivate activated sludge. The interiors of the multiple diversion pipes are connected to branch pipes located on both sides of the culture rack, and the interior of the diversion pipes is structured with a regulating component for changing the gas flow direction.

[0010] Preferably, the scraping assembly includes scraping auger blades fixedly connected to both ends of the cross bar. The scraping auger blades spiral to the surface of the cross bar, and sewage guiding grooves are formed on the outer surface of the scraping auger blades. A blade adapted to the inside of the rotating tube is fixedly connected to the middle end of the cross bar, and the cross bar is rotatably connected to the inside of the rotating tube.

[0011] Preferably, the liquid discharging assembly includes a plurality of horizontal tubes communicated with the inside of the liquid storage shell. Drainage tubes communicated with the bronchus are connected to the bottoms of the plurality of horizontal tubes. A ball valve body for blocking the drainage tube is arranged inside the horizontal tube, and a spring fixedly connected to the ball valve body is fixedly connected to the inside of the horizontal tube.

[0012] Preferably, the adjusting assembly includes a piston piece arranged inside the shunt tube. The piston piece is adapted to the branch tube. A support bar for the piston piece to slide is fixedly connected to the inside of the branch tube. A fixed sealing piece is fixedly connected to the inside of the shunt tube. A movable sealing piece adapted to the fixed sealing piece is rotatably connected to the inside of the fixed sealing piece. A transmission handle is fixedly connected to one side of the movable sealing piece. A common connecting seat is arranged inside the shunt tube. A crank rotatably connected to the common connecting seat is rotatably connected to one side of the transmission handle. Hinge handles rotatably connected to the piston piece are rotatably connected to both ends of the common connecting seat.

[0013] Preferably, a sliding rod is slidably connected to the bottom of the shunt tube. The top of the sliding rod extends into the shunt tube and is fixedly connected to the common connecting seat. A lever is rotatably connected to the bottom of the shunt tube. One end of the lever is connected to the sliding rod through a universal ball. A return spring for the sliding rod to reset itself is sleeved on the outer surface of the sliding rod. A buoyancy plate is fixedly connected to the end of the lever away from the universal ball.

[0014] Preferably, a stirring blade is rotatably connected to the inside of the buoyancy plate. A plurality of air vent holes are formed on the outer surface of the branch tube. A side tube extending to one side of the stirring blade is communicated with the top of the branch tube.

[0015] Preferably, a sewage discharge pipe is communicated with the bottom of the inner tank body. An electromagnetic three-way valve is fixedly connected to the inside of the sewage discharge pipe. An empty pipe for draining water is opened at one end of the electromagnetic three-way valve away from the sewage discharge pipe.

[0016] Preferably, a sewage discharge partition groove for storing impurities is formed between the treatment tank and the inner tank body, and an oil discharge pipe for sewage discharge is communicated with the bottom of the sewage discharge partition groove.

[0017] Preferably, a channel for waste water to enter is opened at the top of the treatment tank. A pressure gauge is fixedly connected to the top of the treatment tank. A drain pipe for discharging waste water is communicated with one side of the treatment tank.

[0018] The present invention also provides a wastewater treatment method for the production process of choline chloride, comprising the following steps:

[0019] S1. During use, first pour the wastewater generated in the production process of choline chloride into the interior of the treatment tank, and it first passes through the grille and then falls into the interior of the inner tank body;

[0020] S2. Deliver the gas through the intake pipe into a plurality of shunt pipes and then into the interior of the rotating pipe. At this time, the gas is discharged through a plurality of bronchial tubes to contact the wastewater and disturb the wastewater. Meanwhile, the scraping assembly operates to clean the grille;

[0021] S3. Meanwhile, when the rotating pipe rotates, a certain centrifugal force will be generated, and this force will drive the liquid discharge assembly to operate and discharge the volume in the liquid storage shell to react with the wastewater;

[0022] S4. Pour the preliminarily treated wastewater into the inner bottom of the treatment tank to react with the activated sludge in the culture rack for secondary treatment. At this time, as the water level gradually rises, it will drive the adjustment assembly to operate and change the flow path of the gas to supply gas to the culture rack.

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

[0024] 1. Introduce external gas through the intake pipe and evenly distribute it to the interior of the treatment tank via the shunt pipes, achieving sufficient aeration of the wastewater, increasing the dissolved oxygen content in the wastewater, helping to accelerate the biological treatment process, and improving the treatment efficiency. The driving force generated when the gas is discharged through the bronchial tubes can drive the rotation of the rotating pipe, thereby driving the wastewater to be stirred, making the pollutants in the wastewater more evenly distributed, enhancing the contact opportunity between the wastewater and microorganisms, and promoting the degradation of pollutants. The grille effectively intercepts large particles and suspended substances in the wastewater, preventing these impurities from entering the subsequent treatment links, and ensuring the stability and treatment effect of the treatment system. The scraping auger blades spiral on the cross bar. As the cross bar rotates, it can continuously scrape off the impurities and grease on the surface of the grille, achieving efficient removal of fine particles and grease in the wastewater. The sewage guiding groove collects and lifts the scraped impurities and grease into the interior of the sewage guiding groove. As the cross bar rotates, it continuously transports the impurities to the sewage discharge partition groove, realizing the continuous discharge of impurities and avoiding the accumulation and blockage of impurities. The electromagnetic three-way valve: By switching the electromagnetic three-way valve, the discharge path of the wastewater can be conveniently controlled, realizing the separate discharge of the preliminarily treated wastewater and the sediment, improving the flexibility and efficiency of the treatment. Discharge the impurities and grease in the sewage discharge partition groove, and these substances can be further treated or recycled, reducing environmental pollution and realizing the effective utilization of resources.

[0025] 2. Drainage Component The design of this component is very ingenious. It uses the centrifugal force generated by the gas discharged from the bronchus to drive the movement of the ball valve body, thereby opening the drainage channel. This mechanism not only realizes the automatic dosing of the coagulant, but also the dosing timing and amount are closely related to the gas flow, ensuring that the coagulant can be accurately dosed into the wastewater, improving the usage efficiency of the coagulant. The gas discharged from the bronchus not only carries these oils for deoiling treatment, but also drives the startup of the drainage component at the same time, realizing the accurate dosing of the coagulant. This synergistic effect not only improves the removal efficiency of the oils, but also enhances the coagulation effect. Synergy between the electromagnetic three-way valve and the drainage component: When the wastewater undergoes coagulation treatment, the electromagnetic three-way valve can switch to the sewage discharge mode to separate the precipitated impurities and wastewater. The accurate dosing of the drainage component ensures the uniform distribution of the coagulant in the wastewater, thereby improving the precipitation effect and reducing the residue of impurities.

[0026] 3. Branch Pipe and Aeration Hole Through the precise control of the adjustment component, the gas can be shunted into the branch pipe and evenly discharged through the aeration holes, providing sufficient oxygen for the activated sludge, promoting its growth and metabolism, and thereby improving the efficiency of wastewater treatment. The adjustment component can automatically adjust the gas flow path according to the water level of the wastewater without manual intervention, improving the automation degree of the system. The buoyancy plate can rise as the water level of the wastewater rises, and through lever transmission, it automatically triggers the operation of the adjustment component, realizing the intelligent control of the wastewater treatment process. The gas discharged through the side pipe drives the stirring blade to rotate, further disturbing the wastewater, making it fully contact and mix with the activated sludge in the culture rack, and improving the reaction efficiency. This design not only increases the contact area between the wastewater and the activated sludge, but also promotes the faster degradation of pollutants in the wastewater by microorganisms. The culture rack provides a growth environment for the activated sludge, and the rotation of the stirring blade further promotes the mixing and reaction of the wastewater and the activated sludge. The two work together to jointly improve the effect of wastewater treatment. The buoyancy plate not only triggers the operation of the adjustment component, but also indirectly drives the rotation of the stirring blade through lever transmission, realizing the double strengthening of wastewater disturbance and further improving the reaction efficiency of the wastewater and the activated sludge.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Example 1: Please refer to Figure 1 ,Figure 2 and Figure 3 , the present invention provides a technical solution: a wastewater treatment device for the production process of choline chloride, comprising a treatment tank 100 with a cavity inside. An inner tank 101 for preliminary treatment of wastewater is fixedly connected inside the treatment tank 100. An air inlet pipe 102 is connected to the bottom of the treatment tank 100, and a plurality of shunt pipes 103 extending into the inner tank 101 are connected to the top of the air inlet pipe 102. A rotating pipe 104 is rotatably connected to the tops of the plurality of shunt pipes 103. A sewage discharge pipe 105 is connected to the bottom of the inner tank 101. An electromagnetic three-way valve 106 is fixedly connected inside the sewage discharge pipe 105. An empty pipe for draining water is provided at one end of the electromagnetic three-way valve 106 away from the sewage discharge pipe 105. A channel for wastewater to enter is provided at the top of the treatment tank 100. A pressure gauge 108 is fixedly connected to the top of the treatment tank 100. A drain pipe 107 for discharging wastewater is connected to one side of the treatment tank 100. By providing the air inlet pipe 102, external gas can enter the inside of the treatment tank 100 to provide aeration and stirring work. The cooperation of the sewage discharge pipe 105 and the electromagnetic three-way valve 106 can discharge the sediment generated in the preliminarily treated wastewater. The wastewater after preliminary treatment can be discharged through the empty pipe connected to one end of the electromagnetic three-way valve 106.

[0042] It further includes a grille 200, which is fixedly connected inside the inner tank 101 to intercept fine particles in the wastewater. A cross bar 201 is provided above the grille 200 at the top of the rotating pipe 104. A scraping assembly for cleaning the grille 200 is arranged on the outer surface of the cross bar 201. The scraping assembly includes scraping auger blades 202 fixedly connected to both ends of the cross bar 201. The scraping auger blades 202 spiral to the surface of the cross bar 201. By providing the grille 200, large particles and suspended substances in the wastewater can be intercepted. By providing the scraping assembly, the sundries on the surface of the grille 200 can be effectively scraped off, and at the same time, the grease floating on the top of the wastewater can be scraped off.

[0043] Further, please refer to Figure 4 , Figure 5 and Figure 6Moreover, a dirt scraping trough 203 is formed on the outer surface of the dirt scraping auger blade 202. The middle end of the cross bar 201 is fixedly connected with a blade 204 adapted to the inside of the rotating pipe 104, and the cross bar 201 is rotatably connected to the inside of the rotating pipe 104. A sewage discharge partition trough 205 for storing impurities is formed between the treatment tank 100 and the inner tank body 101. The bottom of the sewage discharge partition trough 205 is communicated with an oil outlet pipe 206 for sewage discharge. By arranging the dirt scraping auger blade 202 to spiral on the surface of the cross bar 201, it can rotate following the rotation of the cross bar 201, so that it continuously scrapes the impurities on the surface of the grille 200 inward. At the same time, while the cross bar 201 rotates on its own axis, it can revolve together with the rotating pipe 104, improving its dirt scraping efficiency. The arranged dirt scraping trough 203 can lift the impurities scraped off by the rotation of the cross bar 201 into the inside of the dirt scraping trough 203, and continuously convey the impurities along with the rotation of the cross bar 201, thereby realizing the discharge of impurities.

[0044] Specifically, the gas is conveyed through the air inlet pipe 102 into a plurality of shunt pipes 103 and then enters the inside of the rotating pipe 104. At this time, the gas is discharged through a plurality of bronchial tubes 301 to contact the wastewater and disturb the wastewater. At the same time, when the gas is discharged through a plurality of bronchial tubes 301, a certain driving force will be generated to slowly drive the rotation of the rotating pipe 104. At this time, the rotation of the rotating pipe 104 will drive the cross bar 201 to rotate together with it. At the same time, a part of the gas in the rotating pipe 104 will continuously move upward and pass through the blade 204 to drive the cross bar 201 to rotate on its own axis. At this time, the dirt scraping auger blade 202 fixed on the cross bar 201 rotates to scrape off the impurities on the surface of the grille 200. At the same time, due to the addition of the gas in the wastewater, the grease in the wastewater will be carried by the gas and float to the surface of the grille 200. At this time, the rotation of the dirt scraping auger blade 202 will scrape the sundries to crawl on its surface and enter the dirt scraping trough 203. At this time, the path of the dirt scraping trough 203 follows the movement and rotation of the dirt scraping auger blade 202 to continuously convey the sundries inside it and convey them into the sewage discharge partition trough 205, and finally discharge them through the oil outlet pipe 206.

[0045] In summary, by introducing external gas through the intake pipe 102 and evenly distributing it to the inside of the treatment tank 100 via the shunt pipe 103, sufficient aeration of the wastewater is achieved, increasing the dissolved oxygen content in the wastewater, which helps to accelerate the biological treatment process and improve the treatment efficiency. The driving force generated when the gas is discharged through the bronchial tube 301 can drive the rotation of the rotating tube 104, thereby driving the stirring of the wastewater, making the pollutants in the wastewater more evenly distributed, enhancing the contact opportunity between the wastewater and microorganisms, and promoting the degradation of pollutants. The grille 200 effectively intercepts large particles and suspended solids in the wastewater, preventing these impurities from entering the subsequent treatment process and ensuring the stability and treatment effect of the treatment system. The scraping auger blade 202 spirals on the cross bar 201. As the cross bar 201 rotates, it can continuously scrape off the impurities and grease on the surface of the grille 200, achieving efficient removal of fine particles and grease in the wastewater. The sewage guiding groove 203 collects and lifts the scraped impurities and grease into the inside of the sewage guiding groove 203. As the cross bar 201 rotates, it continuously transports the impurities to the sewage discharge partition groove 205, realizing continuous discharge of impurities and avoiding accumulation and blockage of impurities. The electromagnetic three-way valve 106: By switching the electromagnetic three-way valve 106, the discharge path of the wastewater can be conveniently controlled, realizing separate discharge of the preliminarily treated wastewater and the sediment, improving the flexibility and efficiency of the treatment. The impurities and grease in the sewage discharge partition groove 205 are discharged. These substances can be further treated or recycled, reducing environmental pollution and realizing effective utilization of resources.

[0046] Embodiment 2: Please refer to Figure 3 , Figure 5 and Figure 7 , the present invention also provides a technical solution. Different from the technical solution of Embodiment 1, it is a wastewater treatment device used in the production process of choline chloride, which further includes a liquid storage shell 300 sleeved on the outer surface of the rotating tube 104 and storing a coagulant inside. The outer surface of the rotating tube 104 is evenly communicated with a plurality of bronchial tubes 301 for exhausting gas, and a liquid discharge assembly for transporting the coagulant is arranged on the outer surface of the liquid storage shell 300. By providing the liquid storage shell 300, it can be used to store the solvent for treating the wastewater. The solvent can be discharged into the wastewater for reaction under the cooperation of the liquid discharge assembly. Among them, the liquid discharge assembly can be started to rotate following the flow of the gas, improving the convenience of operation.

[0047] Further, the liquid discharge assembly includes a plurality of horizontal pipes 302 communicated with the inside of the liquid storage shell 300, and liquid discharge pipes 305 communicated with the bronchus 301 are connected to the bottoms of the plurality of horizontal pipes 302. A ball valve body 304 for blocking the liquid discharge pipe 305 is arranged inside the horizontal pipe 302, and a spring 303 fixedly connected to the ball valve body 304 is fixedly connected inside the horizontal pipe 302. By arranging the exhaust of the bronchus 301, the gas can carry the grease in the wastewater upward to realize the oil removal treatment of the wastewater. At the same time, the gas discharged from the bronchus 301 can provide a rotating force for the rotating pipe 104 to form a centrifugal force to drive the ball valve body 304 to be misaligned, so that the horizontal pipe 302 and the liquid discharge pipe 305 are communicated and the liquid is discharged into the inside of the bronchus 301.

[0048] Specifically, when the rotating pipe 104 rotates, a certain centrifugal force will be generated. This force will drive the ball valve body 304 to move inside the horizontal pipe 302 and compress the spring 303, so that the ball valve body 304 is misaligned with the liquid discharge pipe 305, thereby opening the channel between the liquid discharge pipe 305 and the horizontal pipe 302. At this time, the coagulant in the liquid storage shell 300 also enters the horizontal pipe 302 under the action of the centrifugal force and is transported to the bronchus 301 along with the liquid discharge pipe 305. At this time, the gas flowing in the bronchus 301 will carry the coagulant to combine with the wastewater and disturb the wastewater at the same time, improving the mixing efficiency between the two, so that the wastewater reacts with the coagulant and the suspended solids, colloids and some dissolved substances in the sewage form flocs. Subsequently, by stopping the gas supply into the intake pipe 102, the wastewater forms solid-liquid separation through precipitation and discharges impurities through the sewage discharge pipe 105.

[0049] In summary, the design of the liquid drainage component is very ingenious. It uses the centrifugal force generated by the gas discharged from the bronchus 301 to drive the movement of the ball valve body 304, thereby opening the liquid drainage channel. This mechanism not only realizes the automatic dosing of the coagulant, but also the timing and amount of dosing are closely related to the gas flow, ensuring that the coagulant can be accurately dosed into the wastewater, improving the use efficiency of the coagulant. The coagulant combines with the suspended solids, colloids and some dissolved substances in the wastewater to form flocs, which are more easily removed by subsequent precipitation or filtration processes, thus significantly improving the effect of wastewater treatment. The gas discharged from the bronchus 301 is not only used to drive the liquid drainage component, but also disturbs the wastewater at the same time, enhancing the mixing efficiency between the wastewater and the coagulant, making the coagulation process more thorough and uniform. Through the design of the liquid drainage component, the automatic dosing of the coagulant is realized, reducing the need for manual operation and improving the automation degree of the system. The entire system, including the air inlet pipe 102, the rotating pipe 104, the bronchus 301, the liquid storage shell 300 and its liquid drainage component, can work together to form a closed-loop wastewater treatment process. From aeration, stirring, coagulation to precipitation, each step is closely connected, ensuring the high efficiency and stability of wastewater treatment. Since the system can automatically and accurately dose the coagulant, it avoids the waste caused by over-dosing and also reduces the energy consumption caused by improper manual operation. By optimizing the dosing of the coagulant and the mixing process of the wastewater, the efficiency of wastewater treatment is improved, thereby reducing the treatment time and energy consumption. While scraping the impurities on the surface of the grille 200, the scraping auger blade 202 also promotes the movement of the grease on the wastewater surface towards the direction of the bronchus 301. The gas discharged from the bronchus 301 not only carries these greases for deoiling treatment, but also drives the start of the liquid drainage component at the same time, realizing the accurate dosing of the coagulant. This synergistic effect not only improves the removal efficiency of the grease, but also enhances the coagulation effect. Synergy between the electromagnetic three-way valve 106 and the liquid drainage component: When the wastewater undergoes coagulation treatment, the electromagnetic three-way valve 106 can be switched to the sewage discharge mode to separate the precipitated impurities and the wastewater. The accurate dosing of the liquid drainage component ensures the uniform distribution of the coagulant in the wastewater, thereby improving the precipitation effect and reducing the residue of impurities.

[0050] Example 3: Please refer to Figure 8 , Figure 9 and Figure 10, the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1: A wastewater treatment device for the production process of choline chloride, further comprising a culture rack 400, which is filled at the inner bottom of the treatment tank 100 and made of porous materials to cultivate activated sludge. Branch pipes 401 located on both sides of the culture rack 400 are communicated inside each of the plurality of shunt pipes 103, and an adjustment component for changing the gas flow direction is configured inside the shunt pipes 103. By setting the adjustment component, the gas flow path can be changed, so that the gas enters the auxiliary culture rack 400 for secondary treatment of the wastewater. Among them, the adjustment component greatly reduces the complexity of the work operation, improves the treatment efficiency, and at the same time, setting the culture rack 400 can further improve the comprehensiveness of wastewater treatment.

[0051] Further, please refer to Figure 10 , Figure 11 and Figure 12 , the adjustment component includes a piston piece 407 arranged inside the shunt pipe 103, and the piston piece 407 is adapted to the branch pipe 401. A support bar 409 for the piston piece 407 to slide is fixedly connected inside the branch pipe 401. A fixed sealing piece 412 is fixedly connected inside the shunt pipe 103, and a movable sealing piece 408 adapted to it is rotatably connected inside the fixed sealing piece 412. A transmission handle 413 is fixedly connected to one side of the movable sealing piece 408. A common connection seat 416 is arranged inside the shunt pipe 103. One side of the transmission handle 413 is rotatably connected to a crank 414 rotatably connected to the common connection seat 416. Both ends of the common connection seat 416 are rotatably connected to an articulated handle 415 rotatably connected to the piston piece 407. By setting the piston piece 407, the channel between the shunt pipe 103 and the branch pipe 401 can be closed in the initial state, so that the gas enters the inside of the rotating pipe 104 through the shunt pipe 103. As the piston piece 407 is opened, the movable sealing piece 408 will be misaligned with the fixed sealing piece 412 to block the shunt pipe 103, so that the gas is discharged through the branch pipe 401, shunting the gas and changing its flow path.

[0052] Among them, a slide bar 406 is slidably connected to the bottom of the shunt pipe 103. The top of the slide bar 406 extends into the shunt pipe 103 and is fixedly connected to the common connection seat 416. A lever 405 is rotatably connected to the bottom of the shunt pipe 103. One end of the lever 405 is connected to the slide bar 406 through a universal bead 411. A return spring 410 for the slide bar 406 to reset itself is sleeved on the outer surface of the slide bar 406. A buoyancy plate 404 is fixedly connected to the end of the lever 405 away from the universal bead 411. By setting the buoyancy plate 404, it can automatically detect when the wastewater enters the inner bottom of the treatment tank 100 and drive the adjustment component to operate, so that the gas changes its path and enters the inside of the branch pipe 401, providing an aerobic environment for the activated sludge in the culture rack 400, improving its treatment efficiency, and at the same time reducing the operation process to improve the efficiency.

[0053] Furthermore, a stirring blade 417 is rotatably connected inside the buoyancy plate 404. A plurality of air holes 402 are formed on the outer surface of the branch pipe 401. A side pipe 403 extending to one side of the stirring blade 417 is communicated with the top of the branch pipe 401. At the same time, in order to improve the reaction rate between the wastewater and the activated sludge in the culture rack 400, the stirring blade 417 is provided to disturb the flow of the wastewater, thereby improving the reaction rate between the two.

[0054] Specifically, then operate the electromagnetic three-way valve 106 to connect the inner tank body 101 with its empty pipe, and pour the preliminarily treated wastewater into the inner bottom of the treatment tank 100 to react with the activated sludge in the culture rack 400 for secondary treatment. At this time, as the water level gradually rises, the buoyancy plate 404 will be lifted, so that the lever 405 is pried, and then the sliding rod 406 is pulled down through the universal beads 411. Furthermore, the common connecting seat 416 is pushed down to drive one end of the two articulated handles 415 to move, thereby opening the piston piece 407. At the same time, the common connecting seat 416 pulls the crank 414 to tilt and drives the transmission handle 413 to rotate, so that the movable sealing piece 408 is misaligned with the fixed sealing piece 412 to block the channel in the shunt pipe 103. At this time, air is input into the air inlet pipe 102, and the air will be conveyed to the inside of the branch pipe 401 and discharged through a plurality of air holes 402, providing oxygen for the activated sludge in the culture rack 400. At the same time, part of the air will be discharged through the side pipe 403 and blown to the surface of the stirring blade 417, thereby driving the stirring blade 417 to rotate and further disturbing the wastewater to improve the reaction efficiency between the wastewater and the activated sludge in the culture rack 400. After the treatment is completed, the wastewater can be discharged through the drain pipe 107.

[0055] In summary, the culture rack 400 is made of porous materials, providing a good growth environment for activated sludge. Microorganisms in the activated sludge can efficiently degrade organic matter and other pollutants in the wastewater, thus significantly improving the quality of wastewater treatment. Through the precise control of the adjustment component, the branch pipe 401 and the air holes 402 can shunt the gas into the branch pipe 401 and evenly discharge it through the air holes 402, providing sufficient oxygen for the activated sludge, promoting its growth and metabolism, and further improving the efficiency of wastewater treatment. The adjustment component can automatically adjust the gas flow path according to the water level of the wastewater without manual intervention, improving the automation degree of the system. The buoyancy plate 404 can rise with the rise of the wastewater level and drive the adjustment component to operate automatically through the lever 405, realizing the intelligent control of the wastewater treatment process. The gas discharged through the side pipe 403 drives the stirring blade 417 to rotate, further disturbing the wastewater and making it fully contact and mix with the activated sludge in the culture rack 400, improving the reaction efficiency. This design not only increases the contact area between the wastewater and the activated sludge but also promotes the faster degradation of pollutants in the wastewater by microorganisms. The culture rack 400 provides a growth environment for the activated sludge, and the rotation of the stirring blade 417 further promotes the mixing and reaction of the wastewater and the activated sludge. The two work together to jointly improve the effect of wastewater treatment. The buoyancy plate 404 not only triggers the operation of the adjustment component but also indirectly drives the rotation of the stirring blade 417 through the lever 405, realizing the double strengthening of wastewater disturbance and further improving the reaction efficiency of the wastewater and the activated sludge.

[0056] Embodiment 4: Please refer to Figures 1 to 12 , the present invention also provides a technical solution. The difference from the technical solution of Embodiment 1 is: A method for treating wastewater in the production process of choline chloride, including the following steps:

[0057] S1. When in use, first pour the wastewater generated in the production process of choline chloride into the interior of the treatment tank 100 so that it first passes through the grille 200 and falls into the interior of the inner tank body 101. At the same time, close the electromagnetic three-way valve 106 so that the inner tank body 101 cannot communicate with the sewage discharge pipe 105, and then conduct preliminary treatment on it;

[0058] S2. The gas is transported through the intake pipe 102 into multiple shunt pipes 103 and then enters the interior of the rotating pipe 104. At this time, the gas is discharged through multiple bronchial tubes 301 to contact the wastewater and disturb the wastewater. At the same time, when the gas is discharged through multiple bronchial tubes 301, a certain driving force will be generated to slowly drive the rotation of the rotating pipe 104. At this time, the rotation of the rotating pipe 104 will drive the cross bar 201 to rotate together with it. At the same time, a part of the gas in the rotating pipe 104 will continuously move upward and pass through the blades 204 to drive the cross bar 201 to rotate self - sufficiently. At this time, the sewage scraping auger blade 202 is fixed on the cross bar 201 and rotates to scrape the impurities on the surface of the lower grille 200. At the same time, due to the addition of gas in the wastewater, the grease in the wastewater will be carried by the gas and float to the surface of the grille 200. At this time, the rotation of the sewage scraping auger blade 202 will scrape the sundries to crawl on its surface and enter the sewage guiding groove 203. At this time, the path of the sewage guiding groove 203 follows the movement and rotation of the sewage scraping auger blade 202 to continuously transport the sundries inside it and transport them to the inside of the sewage discharge partition tank 205, and finally discharge through the oil outlet pipe 206;

[0059] S3. At the same time, when the rotating pipe 104 rotates, a certain centrifugal force will be generated. This force will drive the ball valve body 304 to move inside the horizontal pipe 302 and compress the spring 303, causing the ball valve body 304 to be misaligned with the drain pipe 305, thus opening the channel between the drain pipe 305 and the horizontal pipe 302. At this time, the coagulant in the liquid storage shell 300 also enters the horizontal pipe 302 under the action of the centrifugal force and is transported to the bronchial tube 301 along with the drain pipe 305. At this time, the gas flowing in the bronchial tube 301 will carry the coagulant to combine with the wastewater and disturb the wastewater at the same time, improving the mixing efficiency between the two, causing the wastewater and the coagulant to react and the suspended solids, colloids and some dissolved substances in the sewage to form flocculants. Subsequently, by stopping the gas supply into the intake pipe 102, the wastewater forms solid - liquid separation through precipitation and discharges the impurities through the sewage discharge pipe 105;

[0060] S4. Subsequently, operate the electromagnetic three-way valve 106 to connect the inner tank body 101 with its empty pipe, and pour the preliminarily treated wastewater into the inner bottom of the treatment tank 100 to react with the activated sludge in the culture rack 400 for secondary treatment. At this time, as the water level gradually rises, the buoyancy plate 404 will be lifted, causing the lever 405 to be pried, and then the sliding rod 406 will be pulled down through the universal beads 411. Furthermore, the common connection seat 416 will be pushed down to drive one end of the two articulated handles 415 to move, thus opening the piston piece 407. At the same time, the common connection seat 416 pulls the crank 414 to tilt and drives the transmission handle 413 to rotate, so that the movable sealing piece 408 is misaligned with the fixed sealing piece 412, thereby blocking the channel in the shunt pipe 103. At this time, air is input into the inlet pipe 102, and the air will be transported to the inside of the branch pipe 401 and discharged through a plurality of air holes 402, providing oxygen for the activated sludge in the culture rack 400. At the same time, part of the air will be discharged through the side pipe 403 and blown to the surface of the stirring blade 417, thereby driving the stirring blade 417 to rotate and further disturbing the wastewater to improve the reaction efficiency between the wastewater and the activated sludge in the culture rack 400. After the treatment is completed, the wastewater can be discharged through the drain pipe 107.
