Description

Technical Field

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

[0002] As an important organic compound, choline chloride is widely used in food, medicine, chemical industry and other fields. However, a large amount of wastewater is generated in the production process of choline chloride. These wastewaters contain high concentrations of organic matter and chlorides. If they are directly discharged into the environment, they will have a serious impact on the surrounding ecological environment. Therefore, the development of an efficient wastewater treatment device is of great significance for the sustainable development of choline chloride production and environmental protection.

[0003] For example, the patent document with the prior art announcement number CN222138865U discloses a desizing wastewater treatment pool, including a wastewater treatment pool, a plurality of airflow pipes are evenly arranged at the bottom of the wastewater treatment pool, a plurality of aeration plates are arranged on the airflow pipes, the airflow pipes are gathered to a main air pipe, the main air pipe is connected to an external air intake pipe, an airflow control box for adjusting the airflow size in the air intake pipe is provided on the air intake pipe, a rotating rod is rotatably connected to one side of the airflow control box, the rotating angle of the rotating rod corresponds to the airflow size in the air intake pipe, a rotating adjustment structure for adjusting the angle of the rotating rod is provided on the rotating rod, the rotating angle of the rotating rod rotates with the change of the liquid level in the wastewater treatment pool, and a drain outlet for convenient drainage is provided on the wastewater treatment pool; the treatment pool can change the size of aeration as the liquid level in the pool changes, thereby 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

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.

[0013] Preferably, the bottom of the diverter tube is slidably connected to a slide rod, the top of the slide rod extends to the inside of the diverter tube and is fixedly connected to the common seat, the bottom of the diverter tube is rotatably connected to a lever, one end of the lever is connected to the slide rod through a universal bead, the outer surface of the slide rod is provided with a reset spring for its own reset, and the end of the lever away from the universal bead is fixedly connected to a buoyancy plate.

[0014] Preferably, the buoyancy plate is rotatably connected to a stirring blade inside, a plurality of aeration holes are provided on the outer surface of the branch pipe, and the top of the branch pipe is connected to a side pipe extending to one side of the stirring blade.

[0015] Preferably, the bottom of the inner tank body is connected to a sewage pipe, the interior of the sewage pipe is fixedly connected to an electromagnetic three-way valve, and an empty pipe for drainage is opened at one end of the electromagnetic three-way valve away from the sewage pipe.

[0016] Preferably, a sewage compartment for storing impurities is provided between the processing tank and the inner tank body, and the bottom of the sewage compartment is connected to an oil outlet pipe for sewage discharge.

[0017] Preferably, a channel for wastewater to enter is opened on the top of the treatment tank, a pressure gauge is fixedly connected to the top of the treatment tank, and a drainage pipe for wastewater to be discharged is connected to one side of the treatment tank.

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

[0019] S1. When in use, the wastewater generated in the production process of choline chloride is first poured into the interior of the treatment tank so that it first passes through the grid and falls into the interior of the inner tank body;

[0020] S2, the gas is transported to a plurality of shunt pipes through an air inlet pipe and then enters the interior of a rotary pipe, at which time the gas is discharged through a plurality of bronchial pipes and contacts with wastewater to disturb the wastewater, while the scraping assembly operates to clean the grille;

[0021] S3. When the rotating tube rotates, a certain centrifugal force will be generated, which will drive the liquid discharge assembly to discharge the volume in the liquid storage shell and mix with the wastewater for reaction;

[0022] S4, it pours the initially 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 regulating component to operate and change the flow path of the gas to provide gas for the culture rack.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. External gas is introduced through the air inlet pipe and evenly distributed to the inside of the treatment tank through the diversion pipe, which realizes the full aeration of the wastewater, increases the dissolved oxygen content in the wastewater, helps to accelerate the biological treatment process and improve the treatment efficiency. The driving force generated when the gas is discharged through the bronchus can drive the rotating tube to rotate, and then drive the wastewater to stir, so that the pollutants in the wastewater are more evenly distributed, enhance the contact opportunity between the wastewater and microorganisms, and promote the degradation of pollutants. The grille effectively intercepts large particles and suspended matter in the wastewater, prevents these impurities from entering the subsequent treatment links, and ensures the stability and treatment effect of the treatment system. The scraping auger piece hovers on the crossbar. As the crossbar rotates, it can continuously scrape off the impurities and grease on the surface of the grille, realizing the efficient removal of fine particles and grease in the wastewater. The sewage guide trough collects and lifts the scraped impurities and grease to the inside of the sewage guide trough. As the crossbar rotates, the impurities are continuously transported to the sewage compartment, realizing the continuous discharge of impurities and avoiding the accumulation and blockage of impurities. Solenoid three-way valve: By switching the solenoid three-way valve, the discharge path of wastewater can be easily controlled, and the preliminary treatment of wastewater and sediment can be discharged separately, which improves the flexibility and efficiency of treatment. Impurities and grease in the sewage compartment are discharged, and these substances can be further processed or recycled, which not only reduces environmental pollution, but also realizes the effective utilization of resources.

[0025] 2. The design of the drainage component is very clever. It uses the centrifugal force generated by the gas discharged from the bronchus to drive the ball valve body to move, thereby opening the drainage channel. This mechanism not only realizes the automatic delivery of coagulants, but also the timing and amount of delivery are closely related to the flow of gas, ensuring that the coagulant can be accurately delivered to the wastewater, improving the efficiency of the use of the coagulant, and the gas discharged from the bronchus not only carries these greases to achieve degreasing treatment, but also drives the start of the drainage component at the same time, realizing the precise delivery of coagulants. This synergistic effect not only improves the efficiency of grease removal, but also enhances the coagulation effect. The coordination of the electromagnetic three-way valve and the drainage component: After the wastewater has been coagulated, the electromagnetic three-way valve can be switched to the sewage discharge mode to separate the precipitated impurities from the wastewater. The precise delivery of the drainage component ensures the uniform distribution of the coagulant in the wastewater, thereby improving the precipitation effect and reducing the residual impurities.

[0026] 3. Branch pipes and aeration holes Through the precise control of the regulating component, the gas can be diverted into the branch pipe and discharged evenly through the aeration hole, providing sufficient oxygen for the activated sludge, promoting its growth and metabolism, and thus improving the efficiency of wastewater treatment. The regulating component can automatically adjust the flow path of the gas according to the water level of the wastewater, without manual intervention, which improves the automation of the system. The buoyancy plate can rise with the rise of the wastewater level, and automatically trigger the operation of the regulating component through lever transmission, 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, so that it can fully contact and mix with the activated sludge in the culture rack, and improve 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 improve the effect of wastewater treatment. The buoyancy plate not only triggers the operation of the regulating component, but also indirectly drives the rotation of the stirring blade through the lever transmission, achieving double intensification of wastewater disturbance and further improving the reaction efficiency of wastewater and activated sludge.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1 , Figure 2 as well as 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 body 101 for preliminary treatment of wastewater fixedly connected inside the treatment tank 100, an air inlet pipe 102 connected at the bottom of the treatment tank 100, and a plurality of shunt pipes 103 extending into the inner tank body 101 connected at the top of the air inlet pipe 102, and a rotating pipe 104 connected to the top of the plurality of shunt pipes 103 rotating together, a sewage pipe 105 connected at the bottom of the inner tank body 101, an electromagnetic three-way valve 106 fixedly connected inside the sewage pipe 105, and an electromagnetic three-way valve 106 connected to the inner tank body 101. An empty pipe for drainage is provided at one end of the through valve 106 away from the sewage pipe 105, a channel for wastewater to enter is provided on the top of the treatment tank 100, a pressure gauge 108 is fixedly connected to the top of the treatment tank 100, and one side of the treatment tank 100 is connected to a drainage pipe 107 for wastewater discharge. The air inlet pipe 102 is provided to allow external gas to enter the interior of the treatment tank 100 to provide aeration and stirring, and the sewage pipe 105 and the electromagnetic three-way valve 106 are provided to discharge the sediment generated in the preliminarily treated wastewater, and the preliminarily treated wastewater can be discharged through the empty pipe connected to one end of the electromagnetic three-way valve 106.

[0042] It also includes a grille 200, which is fixedly connected to the inside of the inner tank body 101 and is used to intercept fine particles in the wastewater. The top of the rotating tube 104 extends to the top of the grille 200 and is provided with a cross bar 201. The outer surface of the cross bar 201 is provided with a scraping assembly for cleaning the grille 200. The scraping assembly includes a scraping auger piece 202 fixedly connected to both ends of the cross bar 201, and the scraping auger piece 202 is spiraled to the surface of the cross bar 201. By setting the grille 200, large particles and suspended matter in the wastewater can be intercepted, and the scraping assembly can effectively remove debris on the surface of the grille 200, and at the same time, grease floating on the top of the wastewater can be removed.

[0043] For further information, see Figure 4 , Figure 5 as well as Figure 6The outer surface of the scraping auger piece 202 is provided with a sewage guide groove 203, the middle end of the cross bar 201 is fixedly connected with a blade 204 adapted to the inside of the rotating tube 104, and the cross bar 201 is rotatably connected to the inside of the rotating tube 104, and a sewage discharge compartment 205 for storing impurities is provided between the processing tank 100 and the inner tank body 101, and the bottom of the sewage discharge compartment 205 is connected with an oil outlet pipe 206 for sewage discharge, and the sewage scraping auger piece 202 is arranged to hover on the surface of the cross bar 201 and rotate with the rotation of the cross bar 201, so that it continuously scrapes impurities on the surface of the grille 200, and at the same time, the cross bar 201 can rotate with the rotating tube 104 while rotating, thereby improving its scraping efficiency, and the sewage guide groove 203 can lift the impurities scraped by the cross bar 201 to the inside of the sewage guide groove 203, and continuously transport the impurities with the rotation of the cross bar 201, thereby realizing the discharge of impurities.

[0044] Specifically, the gas is transported to the multiple branch pipes 103 through the inlet pipe 102 and then enters the interior of the rotating pipe 104. At this time, the gas is discharged through the multiple bronchial pipes 301 and contacts the wastewater to disturb the wastewater. At the same time, when the gas is discharged through the multiple bronchial pipes 301, a certain driving force will be generated to slowly drive the rotating pipe 104 to rotate. At this time, the rotation of the rotating pipe 104 will drive the cross bar 201 to rotate with it. At the same time, part of the gas in the rotating pipe 104 will continue to move upward and pass through the blades 204 to drive the cross bar 201 to rotate. At this time, the scraper The auger blade 202 is fixed on the cross bar 201 and rotates to scrape off 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 auger blade 202 will scrape the debris on its surface and enter the sewage guide groove 203. At this time, the path of the sewage guide groove 203 follows the movement and rotation of the auger blade 202 to continuously transport the debris inside it and transport it to the inside of the sewage discharge partition 205, and finally discharged through the oil outlet pipe 206.

[0045] In summary, external gas is introduced through the air inlet pipe 102 and evenly distributed to the inside of the treatment tank 100 through the shunt pipe 103, thereby achieving sufficient aeration of the wastewater, increasing the dissolved oxygen content in the wastewater, and helping to accelerate the biological treatment process and improve the treatment efficiency. The driving force generated when the gas is discharged through the bronchus 301 can drive the rotating tube 104 to rotate, thereby driving the wastewater to stir, so that the pollutants in the wastewater are 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 matter 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 202 hovers on the cross bar 201. As the cross bar 201 rotates, it can continuously scrape off impurities and grease on the surface of the grille 200, achieving efficient removal of fine particles and grease in the wastewater. The sewage guide 203 collects the scraped impurities and grease and lifts them to the inside of the sewage guide 203. As the cross bar 201 rotates, the impurities are continuously transported to the sewage discharge compartment 205, achieving continuous discharge of impurities and avoiding accumulation and blockage of impurities. Solenoid three-way valve 106: By switching the solenoid three-way valve 106, the discharge path of the wastewater can be conveniently controlled to achieve the separate discharge of the preliminary treated wastewater and sediment, thereby improving the flexibility and efficiency of the treatment. The impurities and grease in the sewage discharge compartment 205 are discharged, and these substances can be further processed or recycled, which not only reduces environmental pollution but also realizes the effective utilization of resources.

[0046] Example 2: Please refer to Figure 3 , Figure 5 as well as Figure 7 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a wastewater treatment device used in the production process of choline chloride, further comprising a liquid storage shell 300, which is sleeved on the outer surface of the rotating tube 104 and stores a coagulant inside. The outer surface of the rotating tube 104 is evenly connected with a plurality of bronchial tubes 301 for exhaust, and the outer surface of the liquid storage shell 300 is provided with a drainage component for conveying the coagulant. The liquid storage shell 300 can be used to store a solvent for treating wastewater, and the solvent can be discharged into the wastewater for reaction with the cooperation of the drainage component, wherein the drainage component can rotate and start following the flow of gas, thereby improving the convenience of operation.

[0047] Furthermore, the drainage component includes a plurality of transverse tubes 302 connected to the interior of the liquid storage shell 300, and the bottoms of the plurality of transverse tubes 302 are connected to drainage tubes 305 connected to the bronchial tube 301, a ball valve body 304 is provided inside the transverse tube 302 for blocking the drainage tube 305, and a spring 303 fixedly connected to the ball valve body 304 is fixedly connected inside the transverse tube 302. By arranging the exhaust of the bronchial tube 301, the gas can carry the oil and fat in the wastewater to the upper part to achieve the deoiling treatment of the wastewater. At the same time, the gas discharged from the bronchial tube 301 can provide a rotational force for the rotating tube 104 to form a centrifugal force to drive the ball valve body 304 to be dislocated, so that the transverse tube 302 is connected to the drainage tube 305 and the drainage enters the interior of the bronchial tube 301.

[0048] Specifically, when the rotating tube 104 rotates, a certain centrifugal force will be generated, which will drive the ball valve body 304 to move inside the transverse tube 302 and compress the spring 303, so that the ball valve body 304 and the drain pipe 305 are misaligned, thereby opening the channel between the drain pipe 305 and the transverse tube 302. At this time, the coagulant in the liquid storage shell 300 also enters the transverse tube 302 under the action of centrifugal force and is transported to the bronchus 301 along the drain pipe 305. At this time, the gas flowing in the bronchus 301 will carry the coagulant and combine with the wastewater while disturbing the wastewater, thereby improving the mixing efficiency between the two, so that the wastewater reacts with the coagulant and the suspended matter, colloid and some soluble substances in the sewage form floccules. Subsequently, by stopping the gas supply to the air inlet pipe 102, the wastewater forms solid-liquid separation through sedimentation and discharges impurities through the sewage pipe 105.

[0049] In summary, the design of the drainage component is very clever. It uses the centrifugal force generated by the gas discharged from the bronchus 301 to drive the ball valve body 304 to move, thereby opening the drainage channel. This mechanism not only realizes the automatic delivery of the coagulant, but also the timing and amount of delivery are closely related to the flow of gas, ensuring that the coagulant can be accurately delivered to the wastewater, thereby improving the efficiency of the use of the coagulant. The coagulant combines with the suspended matter, colloids and some soluble substances in the wastewater to form floccules, which are more easily removed by subsequent sedimentation or filtration processes, thereby significantly improving the effect of wastewater treatment. The gas discharged from the bronchus 301 is not only used to drive the 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 sufficient and uniform. Through the design of the drainage component, the automatic delivery of the coagulant is realized, the need for manual operation is reduced, and the degree of automation of the system is improved. The entire system including the air inlet pipe 102, the rotating pipe 104, the bronchial pipe 301, the liquid storage shell 300 and its drainage components can work together to form a closed-loop wastewater treatment process. From aeration, stirring, coagulation to sedimentation, each step is closely connected, ensuring the high efficiency and stability of wastewater treatment. Since the system can automatically and accurately deliver the coagulant, the waste caused by excessive delivery is avoided, and the energy consumption caused by improper manual operation is also reduced. By optimizing the delivery of the coagulant and the mixing process of the wastewater, the efficiency of wastewater treatment is improved, thereby reducing the processing time and energy consumption. While scraping the impurities on the surface of the grille 200, the scraping auger 202 also promotes the movement of grease on the surface of the wastewater toward the bronchial pipe 301. The gas discharged from the bronchial pipe 301 not only carries these greases to achieve degreasing treatment, but also drives the start of the drainage component to achieve accurate delivery of the coagulant. This synergistic effect not only improves the efficiency of grease removal, but also enhances the coagulation effect. The coordination between the electromagnetic three-way valve 106 and the drainage component: After the wastewater is coagulated, the electromagnetic three-way valve 106 can be switched to the sewage discharge mode to separate the precipitated impurities from the wastewater. The precise placement of the drainage component ensures the uniform distribution of the coagulant in the wastewater, thereby improving the precipitation effect and reducing the residual impurities.

[0050] Example 3: Please refer to Figure 8 , Fig. 9 as well as Fig.10The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a wastewater treatment device used in the production process of choline chloride, further comprising a culture rack 400, which is filled in the inner bottom of the treatment tank 100 and is composed of a porous material to cultivate activated sludge, and the interiors of the multiple shunt pipes 103 are all connected with branch pipes 401 located on both sides of the culture rack 400, and the internal structure of the shunt pipes 103 is provided with a regulating component for changing the flow direction of the gas, and the flow path of the gas can be changed by setting the regulating component, so that the gas enters the auxiliary culture rack 400 for secondary treatment of the wastewater, wherein the regulating component greatly reduces the cumbersomeness of the work operation and improves the treatment efficiency. At the same time, setting the culture rack 400 can further improve the comprehensiveness of the wastewater treatment.

[0051] For further information, see Fig.10 , Fig.11 as well as Fig.12 The regulating assembly includes a piston plate 407 disposed inside the shunt pipe 103, and the piston plate 407 is adapted to the branch pipe 401, the branch pipe 401 is fixedly connected to the inside of the piston plate 407 for sliding connection, the shunt pipe 103 is fixedly connected to the inside of the fixed sealing plate 412, and the fixed sealing plate 412 is rotatably connected to the inside of the movable sealing plate 408 adapted thereto, one side of the movable sealing plate 408 is fixedly connected to the transmission handle 413, and the shunt pipe 103 is provided with a common seat 416, and one side of the transmission handle 413 is rotatably connected to the common seat 416. The connecting seat 416 is rotatably connected to the crank 414, and both ends of the connecting seat 416 are rotatably connected to the hinged handle 415 rotatably connected to the piston plate 407. By setting the piston plate 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 interior of the rotating tube 104 through the shunt pipe 103. As the piston plate 407 opens, the movable sealing plate 408 and the fixed sealing plate 412 will be misaligned, thereby blocking the shunt pipe 103 and allowing the gas to be discharged through the branch pipe 401, thereby diverting the gas and changing its flow path.

[0052] Among them, the bottom of the shunt pipe 103 is slidably connected with a slide bar 406, the top of the slide bar 406 extends to the inside of the shunt pipe 103 and is fixedly connected to the common seat 416, the bottom of the shunt pipe 103 is rotatably connected with a lever 405, one end of the lever 405 is connected to the slide bar 406 through a universal bead 411, and the outer surface of the slide bar 406 is sleeved with a reset spring 410 for its own reset, and the end of the lever 405 away from the universal bead 411 is fixedly connected with a buoyancy plate 404. By setting the buoyancy plate 404, it can automatically detect when the wastewater enters the inner bottom of the treatment tank 100, thereby driving 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 operating process to improve efficiency.

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

[0054] Specifically, the electromagnetic three-way valve 106 is then operated to connect the inner tank body 101 with its empty pipe, and the preliminarily treated wastewater is poured 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 is lifted so that the lever 405 is pried, thereby pulling the slide bar 406 downward through the universal ball 411, and then pushing the joint seat 416 downward to pull one end of the two hinged handles 415 to move, thereby opening the piston plate 407. At the same time, the joint seat 416 pulls the crank 414 to tilt and drive the transmission handle 4 13 The rotation causes the movable sealing piece 408 to be misaligned with the fixed sealing piece 412, thereby blocking the channel in the shunt pipe 103. At this time, gas is transmitted to the inside of the air inlet pipe 102, and the gas will be transported to the inside of the branch pipe 401 and discharged through the multiple aeration holes 402 to provide oxygen for the activated sludge in the culture rack 400. At the same time, part of the gas 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 its reaction efficiency with 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, which provides a good growth environment for activated sludge. The microorganisms in the activated sludge can efficiently degrade organic matter and other pollutants in the wastewater, thereby significantly improving the quality of wastewater treatment. Through the precise control of the regulating component, the branch pipe 401 and the aeration hole 402 can be diverted into the branch pipe 401 and evenly discharged through the aeration hole 402, providing sufficient oxygen for the activated sludge, promoting its growth and metabolism, and thus improving the efficiency of wastewater treatment. The regulating component can automatically adjust the flow path of the gas according to the water level of the wastewater without manual intervention, thereby improving the automation of the system. The buoyancy plate 404 can rise with the rise of the wastewater level, and through the transmission of the lever 405, automatically trigger the operation of the regulating component, 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, so that it is fully in contact and mixed with the activated sludge in the culture rack 400, thereby improving the reaction efficiency. This design not only increases the contact area between wastewater and activated sludge, but also promotes faster degradation of pollutants in wastewater by microorganisms. The culture rack 400 provides a growth environment for activated sludge, and the rotation of the stirring blade 417 further promotes the mixing and reaction of wastewater and activated sludge. The two work together to improve the effect of wastewater treatment. The buoyancy plate 404 not only triggers the operation of the regulating component, but also indirectly drives the rotation of the stirring blade 417 through the transmission of the lever 405, achieving double enhancement of wastewater disturbance and further improving the reaction efficiency of wastewater and activated sludge.

[0056] Example 4: Please refer to Figures 1 to 12 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a method for treating wastewater in the production process of choline chloride, comprising the following steps:

[0057] S1. When in use, the wastewater generated in the production process of choline chloride is first poured into the interior of the treatment tank 100 so that it first passes through the grid 200 and falls into the interior of the inner tank body 101, and at the same time, the electromagnetic three-way valve 106 is closed so that the inner tank body 101 cannot be connected to the sewage pipe 105, and then it is preliminarily treated;

[0058] S2, the gas is transported to the multiple branch pipes 103 through the air inlet pipe 102 and then enters the interior of the rotating tube 104. At this time, the gas is discharged through the multiple bronchial tubes 301 and contacts the wastewater to disturb the wastewater. At the same time, when the gas is discharged through the multiple bronchial tubes 301, a certain driving force will be generated to slowly drive the rotating tube 104 to rotate. At this time, the rotation of the rotating tube 104 will drive the cross bar 201 to rotate with it. At the same time, part of the gas in the rotating tube 104 will continue to move upward and pass through the blades 204 to drive the cross bar 201 to rotate. At this time, the scraper The auger blade 202 is fixed on the cross bar 201 and rotates to scrape off 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 scraper auger blade 202 will scrape the debris on its surface and enter the sewage guide groove 203. At this time, the path of the sewage guide groove 203 follows the movement and rotation of the scraper auger blade 202 and continuously transports the debris inside it to the inside of the sewage discharge compartment 205, and finally discharged through the oil outlet pipe 206;

[0059] S3. When the rotating tube 104 rotates, a certain centrifugal force will be generated. This force will drive the ball valve body 304 to move inside the transverse tube 302 and compress the spring 303, so that the ball valve body 304 and the drain pipe 305 are misaligned, thereby opening the channel between the drain pipe 305 and the transverse tube 302. At this time, the coagulant in the liquid storage shell 300 also enters the transverse tube 302 under the action of centrifugal force and is transported to the bronchus 301 along the drain pipe 305. At this time, the gas flowing in the bronchus 301 will carry the coagulant and combine with the wastewater while disturbing the wastewater, thereby improving the mixing efficiency between the two, so that the wastewater reacts with the coagulant and the suspended matter, colloid and some soluble substances in the sewage form floccules. Then, by stopping the gas supply to the air inlet pipe 102, the wastewater forms solid-liquid separation through precipitation and discharges impurities through the sewage discharge pipe 105;

[0060] S4, 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 is lifted so that the lever 405 is pried, thereby pulling the slide bar 406 downward through the universal ball 411, and then pushing the joint seat 416 downward to pull one end of the two hinged handles 415 to move, thereby opening the piston plate 407. At the same time, the joint seat 416 pulls the crank 414 to tilt and drive the transmission handle 41 The rotation causes the movable sealing piece 408 to be misaligned with the fixed sealing piece 412, thereby blocking the channel in the shunt pipe 103. At this time, gas is transmitted to the inside of the air inlet pipe 102, and the gas will be transmitted to the inside of the branch pipe 401 and discharged through the multiple aeration holes 402 to provide oxygen for the activated sludge in the culture rack 400. At the same time, part of the gas 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 disturb the wastewater to improve its reaction efficiency with the activated sludge in the culture rack 400. After the treatment is completed, the wastewater can be discharged through the drain pipe 107.
