Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment and purification, and in particular to a sponge city sewage purification system. Background Art

[0002] "Sponge City" is an innovative concept proposed in recent years in the field of urban water resources management and environmental protection. It aims to optimize urban rainwater management, sewage treatment and water resource utilization by simulating the natural water cycle process. The core idea of ​​this concept is to make the city like a sponge, which can effectively absorb, store, infiltrate, purify and reuse rainwater, thereby alleviating urban water pollution.

[0003] As an important part of sponge city construction, sewage purification technology aims to improve sewage treatment effects, reduce treatment energy consumption, and improve water quality through a series of ecological purification methods. As a mature water treatment process, flocculation technology has been widely used in sewage treatment, wastewater reuse, and drinking water purification. The flocculation process mainly involves adding flocculants to sewage to promote the mutual adsorption and aggregation of fine particles and colloids in the water to form larger flocs. These flocs can be removed from the water by gravity sedimentation, filtration, and other methods, significantly improving the water quality.

[0004] At present, the method of adding flocculants to the entire sewage pool or sewage tank is used to quickly treat a large amount of sewage. The main advantages of this method are high treatment efficiency, ability to treat a large amount of sewage at one time, and simplicity, high degree of automation in the operation process, and suitable for large-scale sewage treatment systems.

[0005] In sponge cities, sewage treatment usually relies on multiple small, distributed treatment units, such as rain gardens, infiltration wells, artificial wetlands, etc. These small systems have a small treatment capacity. When the sewage volume is small, the conventional flocculant dosage ratio is usually based on large-scale system designs, which assume a larger sewage treatment capacity and a higher water flow rate. For small-scale systems, due to the small water volume, the actual amount of flocculant required is much lower than the amount calculated on a large scale. As a result, the conventional ratio calculation will result in excessive flocculant dosage, and the optimal treatment effect cannot be achieved. Summary of the invention

[0028] In summary, the present invention mainly has the following beneficial effects:

[0029] In the present invention, by setting a plurality of reagent chambers, reagents can be selectively injected into different reagent chambers according to the actual water quality requirements of sewage, so as to meet the sewage treatment requirements under different water quality conditions. The multiple designs of the reagent chamber can respectively accommodate different types of reagents, such as flocculants, flocculation aids, etc., so that the reagents can be flexibly selected for treatment according to the pollutant types and concentrations of sewage in different purification stages, effectively improving the adaptability and efficiency of sewage treatment. During the purification process, the moving part can control the position of the mixing chamber. When the mixing chamber moves upward to a preset position, the mixing chamber can be opened to receive sewage, and when the mixing chamber moves downward to a preset position, the mixing chamber can be opened to release liquid. The fixed volume in the mixing chamber ensures that the amount of sewage treated each time is consistent and is not affected by water flow fluctuations or external interference. By setting a baffle in the mixing chamber and supporting it with an elastic member, when the injection part injects the medium, the pressure change in the mixing chamber forces the baffle to move downward, thereby freeing up more space to accommodate the reagent. The pressure change not only ensures that the reagent can fully contact and react with the sewage, but also effectively improves the combination efficiency of the reagent and the pollutant, and improves the flocculation effect. The generation of pressure can promote the turbulence of the liquid, increase the contact frequency between the reagent and the pollutant, and improve the reaction rate, thereby optimizing the sewage treatment effect. The mixing chamber is used to move up and down to receive and release sewage, which can extend the contact time between sewage and the reagent, and further improve the utilization rate and reaction efficiency of the reagent. In general, the present invention effectively improves the sewage treatment efficiency, the reagent utilization rate and the resource utilization rate by quantitatively adding sewage, accurately controlling the injection amount of the reagent and optimizing the mixing process by pressure changes, and overcomes the problem of unstable treatment effect caused by inaccurate or excessive dosage of the reagent in the prior art.

[0030] In the present invention, by setting a plurality of reagent chambers and flexibly selecting the use of reagents according to the changes in water quality, the reagent chamber can be selectively left empty and filled with air. When air is injected into the mixing chamber, bubbles can be formed in the mixing chamber, which enhances the fluidity of the liquid, improves the mixing efficiency, and promotes the full contact and reaction between the reagent and the sewage. The generation of bubbles not only enhances the turbulence of the liquid and helps the reagent to be evenly distributed, but also can provide necessary oxygen support in certain specific circumstances, such as the oxidation and degradation of organic matter, promote the degradation reaction of harmful substances, and further improve the treatment efficiency. The injection of air introduces more dynamic flow into the liquid in the mixing chamber, ensures that the reagent is in full contact with the pollutants in the sewage (such as suspended particles, colloids, etc.), and enhances the flocculation reaction. Especially for sewage with poor water quality and high suspended matter concentration, the effect of air enables the reagent to play a role quickly and evenly, effectively improving the reaction speed and effect of the entire sewage purification process.

[0046] 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.

[0047] refer to Figure 1-Figure 9 , a sponge city sewage purification system, comprising:

[0048] Purification box 100;

[0049] A mixing chamber 101 is provided in the purification box 100, a partition 102 is provided in the mixing chamber 101, an elastic member 103 is provided between the partition 102 and the mixing chamber 101, and the elastic member 103 can be a spring, and a pressure chamber 104 is formed between the partition 102 and the mixing chamber 101;

[0050] A top box 105 is disposed on the top of the purification box body 100, and a sewage chamber 106 and a plurality of drug chambers 107 are formed in the top box 105;

[0051] The mixing part 108 is disposed in the mixing chamber 101 and is rotatably disposed in the mixing chamber 101;

[0052] The bottom box 109 provided at the bottom of the purification box 100 is used to receive sewage and liquid of the medicine;

[0053] A moving component disposed between the mixing chamber 101 and the purification box 100, used to move the position of the mixing chamber 101 up and down;

[0054] The conveying component disposed between the mixing chamber 101 and the top box 105 is used to open the mixing chamber 101 and the top box 105 when the mixing chamber 101 moves upward to a preset position, so that the sewage is quantitatively conveyed into the mixing chamber 101;

[0055] The injection component disposed between the medicine chamber 107 and the mixing chamber 101 is used to quantitatively transport the medium in the medicine chamber 107 into the mixing chamber 101 when the mixing chamber 101 moves downward to a preset position;

[0056] When the mixing chamber 101 moves, the mixing part 108 can rotate in the mixing chamber 101;

[0057] When the mixing chamber 101 moves downward to a preset position, its bottom can automatically open to release the liquid into the bottom box 109;

[0058] By setting the top box 105, the sewage source can be connected to the top box 105 during application, and a part of the sewage liquid can be temporarily stored by the top box 105. The sewage chamber 106 in the top box 105 can temporarily store the sewage to be treated, ensuring the liquid flow rate during the entire sewage purification process. There are multiple reagent chambers 107, and the reagent chambers 107 can accommodate different types of reagents, such as flocculants, flocculation aids, etc. According to actual needs, the design of the reagent chamber 107 allows the flocculant to be placed in one or more reagent chambers 107, and different reagents can also be flexibly selected for use in different purification stages, which enables the entire purification process to more accurately respond to the types and concentration changes of pollutants in the sewage, thereby effectively improving the sewage treatment efficiency. In the actual purification process, the position of the mixing chamber 101 can be adjusted by using moving parts. By moving the position of the mixing chamber 101 upward, the mixing chamber 101 is gradually approached to the top box 105. When the mixing chamber 101 moves upward to a preset position, the communication channel between the mixing chamber 101 and the top box 105 is opened. The volume in the mixing chamber 101 is determined. When the mixing chamber 101 is opened, the sewage flows freely in the mixing chamber 101. Specifically, the volume of the mixing chamber 101 is determined during the design, and only the appropriate delivery time needs to be controlled. The amount of sewage poured into the mixing chamber 101 each time remains unchanged, ensuring that the amount of sewage treated each time is consistent with the preset standard, and ensuring that the amount of sewage entering the mixing chamber 101 each time is consistent and not affected by other factors. When the mixing chamber 101 moves upward to the limit position and stops for a predetermined time, sewage is poured into the mixing chamber 101 during this process. At this time, the moving part starts to move the position of the mixing chamber 101 downward. When the mixing chamber 101 starts to move downward, the top of the mixing chamber 101 is automatically closed, sealing the sewage and blocking its further flow. At this time, the top sealing mechanism of the mixing chamber 101 ensures that the sewage will not leak out or be disturbed by other liquids, ensuring the accuracy of the subsequent agent injection process. When the mixing chamber 101 continues to move downward to the preset position, the injection part starts to work, accurately extracts the medium in the agent chamber 107, and quantitatively delivers the required medium to the mixing chamber 101. The injection part can inject the agent into the mixing chamber 101 at a predetermined rate and accuracy according to the set agent dosage, ensuring that the agent and sewage are fully mixed and reacted in the mixing chamber 101, thereby effectively improving the sewage purification effect. The quantitative delivery of the agent ensures the accurate addition of the agent, avoids the problem of excessive or insufficient, improves the efficiency of agent use and reduces resource waste. It is worth noting that two different liquids can be injected into one box. Since liquids are incompressible, the design of the mixing chamber 101 must take into account the volume and space requirements of each liquid.The purpose of the design of the partition 102 is to reasonably separate the space between sewage and medicine to avoid unnecessary interference between the two during the injection process. The partition 102 is supported by the elastic member 103. The selection of the elastic member 103 enables the partition 102 to effectively resist the gravity of sewage when carrying sewage, prevent the partition 102 from displacement or deformation, and ensure the stable storage of sewage. At the same time, the supporting force of the elastic member 103 is adjustable, so that the partition 102 can produce a corresponding movement reaction when the medicine is added. When the injection component works and quantitatively delivers the medium (such as flocculant) to the mixing chamber 101, the pressure in the mixing chamber 101 increases due to the addition of the medicine. Due to the incompressibility of the liquid, the additional pressure will force the partition 102 to move downward, thereby freeing up more space to accommodate the injected medicine. Through this design, the mixing chamber 101 can effectively hold sewage and medicine, and always remain stable during the injection of the two liquids, ensuring the smooth progress of the entire sewage treatment process, and avoiding the problem of unstable treatment effect or waste of medicine due to volume limitation or uneven distribution. At the same time, this pressure change helps to ensure that the agent can fully contact the sewage in the mixing chamber 101. As the partition 102 moves downward, the space in the mixing chamber 101 increases. This change not only helps to accommodate more agents, but also accelerates the contact and mixing of the agent and sewage through the action of pressure. Specifically, in the mixing chamber 101, the agent reacts with the suspended matter and colloidal pollutants in the sewage to form flocs. In this process, the agent combines with the pollutants through surface adsorption and chemical reactions to form larger flocs. The pressure change helps to increase the collision probability between the agent and the pollutant, prompting more pollutants to contact the agent, thereby improving the flocculation effect. This pressure-driven effect accelerates the aggregation process of particulate matter in the sewage, making the reaction faster and the reaction effect better. With the injection of the medium, the pressure generated will continue to change, and the flow state of the liquid in the mixing chamber 101 will also change. The pressure may cause the turbulence of the liquid to increase, and this turbulence allows the agent to fully contact and collide with the suspended matter in the sewage, which helps to enhance the activity of the flocculant. This fluid dynamic effect caused by pressure can not only break the surface tension of the liquid, but also avoid the agglomeration of the reagent particles, maintain the high efficiency of the reagent, and further optimize the flocculation effect. In addition, the pressure change ensures that the reagent can be quickly and evenly distributed in the sewage, rather than deposited or aggregated in the container. This can avoid the waste of reagents and improve the efficiency of the use of reagents. Because the reagent molecules can be evenly distributed and contact more pollutants, the consumption of the reagent is optimized, the reaction efficiency is greatly improved, thereby reducing the use of the reagent and saving resources. Therefore, the change in pressure also makes the fluid dynamic effect between the reagent and the sewage more obvious, thereby improving the reaction rate and effect of the reagent and ensuring the efficient flocculation process.In addition, in sponge cities, sewage treatment usually relies on multiple small, distributed treatment units, such as rain gardens, infiltration wells, artificial wetlands, etc. These small systems have a small treatment capacity, and the sewage composition varies greatly. The sewage may contain different types of pollutants, and their concentrations fluctuate greatly. This requires the sewage treatment system to be flexible and adaptable to cope with sewage from different sources and its changing water quality. In this context, setting up multiple reagent chambers 107 and flexibly deploying reagents according to changes in sewage water quality has become an effective solution. When the water quality is relatively poor, one or more of the reagent chambers 107 can be injected with reagents to adapt to changes in different types and concentrations of pollutants. For example, when the concentration of suspended matter in sewage is high, flocculants can be injected into the reagent chamber 107 to remove particulate matter in the water through flocculation reaction; when there are toxic and harmful substances in the water, specific adsorbents or chemical reagents can be added to improve the water quality. This flexible reagent deployment scheme can make sewage treatment more accurate and avoid waste of resources or poor treatment effects caused by excessive or insufficient reagents. In addition, the design of the reagent chamber 107 enables the dosage of the reagent to be adjusted in real time according to the actual situation of the sewage, so that the treatment process has higher adaptability and efficiency. When the water quality is relatively good, one or more reagent chambers 107 can be selectively reserved and left vacant without using the reagent. At this time, when the injection component is working, the air in the reagent chamber 107 will also be injected into the mixing chamber 101. The injection of air can introduce bubbles into the mixing chamber 101, improve the fluidity of the liquid, and help the sewage and the reagent to be more fully stirred and mixed in the mixing chamber 101. The generation of bubbles increases the turbulence of the liquid flow, ensures that the sewage and the reagent are evenly distributed during the mixing process, and improves the mixing effect. In some sewage treatment, especially when organic pollutants (such as ammonia nitrogen, chemical oxygen demand, etc.) need to be oxidized and degraded, the injection of air can provide oxygen support and promote the occurrence of oxidation reactions. Oxygen in the air can react with pollutants to help remove organic matter in the water. By controlling the vacancy and use of the reagent chamber 107, the system can flexibly adapt to changes in water quality and respond appropriately to different sewage treatment needs without frequently adjusting the operation mode of the entire system. Further, when the moving parts work to allow the mixing chamber 101 to continue to move downward and move closer to the bottom box 109, the mixing section 108 set in the mixing chamber 101 can rotate with the movement of the mixing chamber 101. The rotation of the mixing section 108 can produce a more intense stirring effect to ensure that the sewage and the reagent are in full contact in the mixing chamber 101. The rotating mixing section 108 evenly distributes the solid particles, colloidal substances and reagents in the sewage, avoiding the problems of uneven aggregation and uneven sedimentation, and improving the flocculation effect. The rotating mixing section 108 can help the pollutants and the reagents to fully react before sedimentation, increase the contact area of ​​the reagents, and enhance the flocculation reaction, thereby improving the efficiency of the subsequent sedimentation process.Especially for the tiny particles suspended in the sewage, the rotary mixing can effectively avoid the secondary dispersion of the particles, enhance the stability of the flocs, and promote the pretreatment before sedimentation. In the process of the mixing part 108 moving downward, the sewage and the liquid of the agent can be allowed to stay and move in the mixing chamber 101, thereby increasing the contact time between the agent and the sewage, which is particularly important for the reaction rate of the agent, especially for agents that require a certain reaction time to exert their effects, such as flocculants, flocculants, etc. By extending the contact time, the utilization rate of the agent can be improved to ensure more efficient sewage purification. When the mixing chamber 101 is driven by the moving parts to descend to the preset position, its bottom can be automatically opened to release the liquid into the bottom box 109 to complete a purification cycle. This design realizes the rapid discharge of the sewage and the agent after mixing through the automatically opened bottom release mechanism, effectively avoiding the liquid from being retained in the mixing chamber 101 for too long, thereby reducing the possibility of excessive reaction between the agent and the sewage, and ensuring the efficiency and stability of the treatment process. Each release of liquid is precisely calculated and controlled to ensure that the quality and effect of each batch of treated liquid are optimized in each purification cycle. The released liquid can flow smoothly into the bottom box 109 for subsequent sedimentation, filtration or other purification steps to further purify the water quality. This automated release mechanism not only improves the operating efficiency of the system, but also reduces the need for manual intervention, making the entire sewage treatment process simpler and more reliable. Compared with the prior art, in which sewage and reagents are mixed in a certain box or purification tank, the present application optimizes the mixing process and reaction time, which can not only more accurately control the dosage of the reagent, but also ensure that the reagent has sufficient contact time with the pollutants in the sewage, thereby enhancing the effect of the flocculation reaction and improving the overall treatment efficiency. It solves the problem that the dosage ratio of reagents such as flocculants is difficult to control when treating and purifying sewage in the prior art, and it is easy to cause excessive or insufficient addition that affects the purification effect.

[0059] As a further solution of the present invention, the conveying component includes a liquid inlet 200 opened at the top of the mixing chamber 101, a baffle a201 for covering the liquid inlet 200 is provided on the inner top surface of the mixing chamber 101, a spring a202 is connected between the baffle a201 and the liquid inlet 200, a closed tube 203 is connected between the sewage chamber 106 and the purification box 100, a spring b204 is connected between the closed tube 203 and the top box 105, a connecting ring 205 is connected to the outer wall of the closed tube 203, a plurality of connecting ports 206 are opened on the connecting ring 205, a closing strip 207 sleeved with the connecting port 206 is connected to the purification box 100, a limiting rod 208 is connected inside the mixing chamber 101, and the baffle a201 is slidably connected to the limiting rod 208;

[0060] By setting the spring a202, the spring a202 can limit the position of the baffle a201, so that the baffle a201 can be used to close the liquid inlet 200. The elastic potential energy of the spring b204 is greater than that of the spring a202. When the mixing chamber 101 is driven by the moving parts to move upward to the closed tube 203, the closed tube 203 touches the baffle a201, and the baffle a201 slides on the limit rod 208 relative to the mixing chamber 101. At this time, the liquid inlet 200 is opened, and the spring a202 is stretched to generate potential energy, and the baffle a204 is opened. When the baffle a201 slides to the limit position on the limit rod 208, the mixing chamber 101 continues to move upward, and the baffle a201 touches the closed tube 203, so that the closed tube 203 can move upward, and the connecting port 206 gradually leaves the closed strip 207, and the liquid in the sewage tank can reach the liquid inlet 200 through the side wall of the closed tube 203 and the connecting port 206, and the liquid can flow into the mixing chamber 101 along the gap between the baffle a201 and the liquid inlet 200, thereby achieving the purpose of conveying sewage into the mixing chamber 101. The baffle a201 is arranged inside the mixing chamber 101, and even if the pressure in the mixing chamber 101 increases later, it will not cause liquid leakage. The greater the pressure, the closer the baffle is to the liquid inlet 200 under the action of the pressure, thereby enhancing the sealing of the liquid inlet 200.

[0061] As a further solution of the present invention, a liquid outlet 209 is provided at the bottom of the mixing chamber 101, a baffle b210 is provided inside the mixing chamber 101, the baffle b210 covers the liquid outlet 209, the baffle b210 is slidably connected to the limit rod 208, a spring c211 is connected between the baffle b210 and the limit rod 208, a liquid outlet pipe 212 is connected to the bottom box 109, and a plurality of seepage ports 213 are provided on the liquid outlet pipe 212;

[0062] By setting the baffle b210, the baffle b210 can close the liquid outlet 209 through the potential energy of the spring c211. When the mixing chamber 101 moves downward to the position of the liquid outlet pipe 212, the liquid outlet pipe 212 can touch the baffle b210, allowing the baffle b210 to slide relative to the mixing chamber 101. At this time, the liquid outlet 209 can be opened, and the mixed liquid can enter the liquid outlet pipe 212 from the seepage port 213 to reach the bottom box 109 for subsequent further purification.

[0063] As a further solution of the present invention, the injection component includes a connecting tube 300 connected to the top box 105, a connecting tube 301 is connected between the connecting tube 300 and the medicine chamber 107, a piston 302 is provided in the connecting tube 300, a threaded tube 303 slidably connected to the connecting tube 300 is connected to one side of the piston 302, a lead screw a304 threadedly connected to the threaded tube 303 is rotatably connected to the top box 105, a delivery tube 305 is connected to the bottom of the connecting tube 300, an injection hole 306 is opened at the top of the mixing chamber 101, a baffle 307 is sleeved in the injection hole 306, a spring d308 is connected between the baffle 307 and the injection hole 306, and one end of the delivery tube 305 is connected to the injection hole 306;

[0064] By setting the delivery pipe 305, the delivery pipe 305 can be a stainless steel corrugated pipe, a reinforced polyurethane (PU), a reinforced polyethylene (PE) pipe, or some composite pipes with metal wires or steel wires. These pipes can maintain their shape when bent and have a certain resistance to internal and external pressures to ensure that one end of the delivery pipe 305 can move up and down with the mixing chamber 101 without affecting the delivery of the liquid. When in use, when the mixing chamber 101 moves downward to a preset position, the lead screw a304 can be rotated. The rotation of the lead screw a304 can make the piston 302 move linearly through the force of the thread. The liquid in the medicine chamber 107 can enter the connecting pipe 300 through the connecting pipe 301. When the lead screw rotates to move the threaded pipe 303 and the piston 302, after the piston 302 reaches the position of the connecting pipe 301, the liquid or air can be pushed into the delivery pipe 305. The pressure in the delivery pipe 305 will increase, thereby pushing the baffle 307 to move and allowing the spring to stretch to generate potential energy. At this time, the liquid can enter the injection hole 306 and reach the mixing chamber 101, achieving the purpose of injecting the medium in the medicine chamber 107 into the mixing chamber 101. Through this structure, the system can not only accurately control the injection amount of the medicine, but also maintain the smoothness and stability of the injection process. The injection of the medicine is completed under the impetus of the liquid pressure. At the same time, the design of the spring d308 and the baffle 307 further ensures the accuracy and uniformity of the medicine injection. This design avoids the problem of unstable injection caused by liquid pressure fluctuations, improves the efficiency of drug use, enhances the reliability of the system, and ensures the efficient operation of the entire purification process.

[0065] As a further solution of the present invention, the piston 302 includes a connecting plate 309 connected to one end of the threaded tube 303, a vent 310 is provided on the connecting plate 309, a connecting piece 311 is provided on one side of the connecting plate 309, a blocking rod 312 is connected to one side of the connecting piece 311, a limiting piece 313 is connected to one side of the blocking rod 312, a plurality of magnetic strips 314 are provided in the connecting tube 300, and the limiting piece 313 is magnetically attracted to the magnetic strip 314;

[0066] By setting the connecting piece 311, when the threaded tube 303 moves to allow the connecting plate 309 to move toward the top of the delivery tube 305, since there is air or liquid in the connecting tube 300 and the other end of the delivery tube 305 is closed by the blocking piece 307, a moving pressure is generated when the connecting plate 309 moves, allowing the connecting piece 311 to be close to the connecting plate 309, and the sealing rod 312 to close the air vent 310. When the connecting plate 309 moves, the medium can enter the delivery tube 305 and push the blocking piece 307 to move, so that the medium can smoothly reach the mixing chamber 101. When the screw a304 is subsequently reset and rotated to reset the threaded tube 303 and the connecting plate 309, since the injection hole 306 is closed at this time, negative pressure will be generated in the connecting tube 300. The negative pressure can make the connecting piece 311 move relative to the connecting plate 309, and the blocking rod 312 leaves the vent 310. The vent 310 can be opened to eliminate the negative pressure, and the screw a304 can be smoothly reset and rotated to reset the connecting plate 309 to the initial position. The limit piece 313 is magnetically attracted by the magnetic attraction and the magnetic strip 314, which is convenient for the next injection. Through this design, not only can the injection amount of the medicine or gas be accurately controlled, but also the pressure balance in the system can be maintained, thereby improving the efficiency and reliability of the medicine injection process.

[0067] As a further solution of the present invention, the injection component further includes a traction rope 315 wound on the lead screw a304, a spring e316 is connected between the lead screw a304 and the top box 105, and the other end of the traction rope 315 passes through the top box 105 and is connected to the purification box 100 and the mixing chamber 101;

[0068] By setting the traction rope 315, when the mixing chamber 101 moves downward to the preset position, the lead screw a304 can be pulled by the traction rope 315 to rotate. At this time, the spring e316 twists to generate potential energy, providing conditions for the subsequent reset rotation of the lead screw a304. As the mixing chamber 101 continues to move, the lead screw a304 continues to rotate, and the liquid can be slowly injected into the mixing chamber 101. This design effectively ensures the quantitative delivery of the medicine and the accuracy of the injection. Driven by the traction rope 315, the rotation speed of the lead screw a304 can be accurately controlled according to the position of the mixing chamber 101, ensuring that the liquid injection process is smooth and controllable, avoiding the waste of medicine or insufficient reaction caused by too fast or too slow injection.

[0069] As a further solution of the present invention, the mixing part 108 includes a frame 400 disposed in the mixing chamber 101, a plurality of blades 401 are disposed on the outer wall of the frame 400, a plurality of limit frames 402 are connected in the mixing chamber 101, and the frame 400 is slidably connected to the limit frames 402;

[0070] By setting the limiting frame 402, the limiting frame 402 can limit the position of the frame 400. When the mixing chamber 101 moves downward or upward, the position of the frame 400 can be rotated, and the frame 400 rotates about the central axis of the mixing chamber 101. At this time, the multiple blades 401 set on the frame 400 drive the liquid in the mixing chamber 101 to stir as they rotate. The rotation of the frame 400 can generate strong flow and turbulence, effectively promote the full mixing of the agent and the sewage, improve the utilization efficiency of the agent, and enhance the flocculation effect.

[0071] As a further solution of the present invention, a plurality of rotating shafts 403 are rotatably connected to the mixing chamber 101, a gear a404 is connected to the rotating shaft 403, a gear b405 meshing with the gear a404 is connected to the frame 400, a plurality of slide rails 406 are provided on the outer wall of the purification box 100, a rack 407 is connected to the slide rail 406, one end of the rotating shaft 403 extends into the slide rail 406 and is connected to a gear c408 meshing with the rack 407;

[0072] By setting components such as the rotating shaft 403, gears and the slide rail 406, the rotating shaft 403 can be rotated to drive the frame 400 when the mixing chamber 101 moves downward or upward. Specifically, one end of the rotating shaft 403 extends into the slide rail 406 and is connected to a gear c408, which meshes with the rack 407 in the slide rail 406. During the up and down movement of the mixing chamber 101, through the cooperation of the rack 407 and the gear c408, when the rotating shaft 403 rotates, the rotation of the gear a404 drives the gear b405, so that the frame 400 begins to rotate around the central axis of the mixing chamber 101. This design can accurately control the rotation rate and angle of the frame 400 through mechanical transmission, so that the multiple blades 401 on the frame 400 can efficiently stir the liquid in the mixing chamber 101. The liquid is driven by the blades 401 in the mixing chamber 101 to generate strong turbulence, which enhances the contact and reaction effect between the reagent and the suspended matter and colloidal pollutants in the sewage. Through the precise coordination of the rotating shaft 403 and the gears, it is possible to ensure that the stirring effect of the liquid in the mixing chamber 101 is optimal, optimize the dosage and reaction process of the reagents, and improve the efficiency of sewage treatment.

[0073] As a further solution of the present invention, the moving part includes a plurality of lead screws b500 rotatably connected to the purification box 100, the lead screws b500 are connected to gears d501, the purification box 100 is rotatably connected to a gear e502 meshing with the gear d501, the lead screw b500 is a reciprocating lead screw, and the mixing chamber 101 is threadedly connected to the lead screw b500;

[0074] By setting a plurality of lead screws b500 and a gear system, the mixing chamber 101 can be moved up and down. Specifically, the lead screw b500 is connected to the purification box 100 by rotation, and each lead screw b500 is connected with a gear d501, and the gear d501 is meshed with the gear e502 on the purification box 100, and the gear e502 can drive the lead screw b500 to rotate. Since the lead screw b500 is a reciprocating lead screw, when the lead screw b500 is rotated, it can reciprocate along a predetermined track. The mixing chamber 101 is fixed on the lead screw b500 by a threaded connection, and as the lead screw b500 rotates, the mixing chamber 101 can move up and down along the axis direction of the lead screw b500. This design enables the mixing chamber 101 to move up and down accurately as needed in the purification box 100, and the upper and lower positions of the mixing chamber 101 can be accurately controlled by adjusting the rotation rate and direction of the lead screw, thereby adjusting the flow of the liquid and the delivery process of the medicine. In this way, the movement of the mixing chamber 101 can be controlled more accurately, the contact efficiency between the liquid and the reagent can be improved, and sufficient mixing and reaction of the reagent during the sewage treatment process can be ensured.

[0075] As a further solution of the present invention, the moving part further includes a motor 503 connected to the purification box 100, and a gear f504 meshing with the gear e502 is connected to the driving shaft of the motor 503, and the gear f504 is an incomplete gear;

[0076] By setting the motor 503 and the incomplete gear system, the up and down movement of the mixing chamber 101 can be effectively controlled and the precise reception and release of the liquid can be achieved. Specifically, the motor 503 drives the gear f504 to rotate through the drive shaft, and the gear f504 is meshed with the gear e502, thereby driving the screw b500 to rotate. When the motor 503 is working, the motor 503 shaft rotates one circle to allow the screw to rotate a preset number of circles, thereby moving the mixing chamber 101 up and down to the preset limit position. At this time, the mixing chamber 101 can receive liquid or release liquid to complete the injection and discharge in the sewage treatment process. The design of the incomplete gear allows the mixing chamber 101 to stop for a period of time after reaching the limit position, and receive or release the liquid. At this time, the motor 503 does not stop working, but through the tooth profile setting of the incomplete gear, when the mixing chamber 101 reaches the upper and lower limit positions, the system can effectively pause, so that the mixing chamber 101 is stably maintained at the limit position, which is convenient for the precise injection and discharge of the liquid. This not only improves the accuracy of liquid delivery, but also avoids frequent adjustments and movements of the system, ensuring the stability of the liquid treatment process. In addition, when the motor 503 continues to work, the mixing chamber 101 can flexibly collect or release liquid according to demand, and by adjusting the rotation speed of the gear system, the action of the mixing chamber 101 can be further optimized to ensure that the agent and sewage are fully mixed and reacted, thereby improving the sewage purification efficiency and treatment effect.
