Description

[0001] This application is a divisional application of application filed on July 23, 2025, with application number 202511013004.8 and invention title "A High-Efficiency and Energy-Saving Multi-Stage Treatment Device for Textile Wastewater". Technical Field

[0002] This invention belongs to the field of multi-stage treatment of textile wastewater, specifically a high-efficiency and energy-saving textile wastewater treatment equipment. Background Technology

[0003] Textile wastewater refers to various types of wastewater generated during the spinning and weaving process. Textile industrial wastewater generally contains pollutants such as suspended solids, grease, fiber debris, surfactants, and various dyes, and needs to be treated before it can be discharged.

[0004] Because textile wastewater contains a variety of pollutants, it is impossible to remove all pollutants in a single process. Therefore, it generally requires treatment by multiple devices to complete the cleaning process and meet the required discharge conditions.

[0005] Traditional treatment devices have relatively simple functions and can often only treat wastewater with a constant flow rate and a constant degree of pollution. However, textile wastewater exists in many different stages of the textile process, which makes the degree of pollution and discharge of each batch of textile wastewater different. Traditional equipment is difficult to carry out comprehensive harmless treatment.

[0006] Therefore, the present invention provides a high-efficiency and energy-saving textile wastewater treatment equipment. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a high-efficiency and energy-saving textile wastewater treatment equipment, including an equalization tank. A wastewater pipe is installed at the upper rear end of the equalization tank. Two separation tanks are opened inside the equalization tank and connected to each other by multiple connecting pipes. A rotating stirring platform is installed at the bottom inner side of the separation tank. Multiple fan blades are fixed to the outer side of the stirring platform. A dissolved air flotation module is installed at the front end of the equalization tank. A conveyor belt arranged in a ring is installed at the top outer side of the equalization tank. Multiple perforated holes are opened on the surface of the conveyor belt. Two rotating deflector plates are installed between the two separation tanks. The equalization tank and the dissolved air flotation module are connected by a transmission pipe. A receiving cover for receiving the wastewater flow is installed below the conveyor belt and is connected to one of the separation tanks.

[0009] The textile wastewater to be treated is discharged from top to bottom onto a conveyor belt through a wastewater pipe. Due to the perforated surface of the conveyor belt, large impurities such as textile fibers in the wastewater are blocked above the belt. As the conveyor belt moves continuously, it carries these impurities away from their original positions, thus continuously filtering out large impurities. The wastewater after primary filtration is received by a receiving hood and injected into one of the separation tanks. As the wastewater accumulates in the separation tank, some of it enters another separation tank through a connecting pipe. Pollutants in textiles generally include floating matter and sediment; high-density pollutants settle, while low-density pollutants float. The connecting pipe transfers the wastewater from the middle of the tank. The wastewater is moved to another separation tank, while the intermediate tank contains less pollutant, resulting in different levels of contamination in the two tanks. The wastewater with varying contamination levels is then discharged into a transfer pipe at different rates. When a batch of wastewater is more contaminated, the discharge rate from the lower-contamination separation tank is increased; conversely, when a batch is less contaminated, the discharge rate is decreased. This ensures that the mixed wastewater in the transfer pipe maintains a consistent level of contamination and is discharged at a constant rate into subsequent equipment, thus completing secondary wastewater treatment. This setup guarantees that the contamination level of the wastewater injected into the transfer pipe each time is consistent. Similarly, to ensure the smooth operation of subsequent treatment devices; when wastewater in the low-pollution separation tank is consumed rapidly and backflow occurs, the stirring table is activated to rotate, and the fan blades are used to increase the stirring effect, ensuring that the pollutants in the wastewater in the two separation tanks are evenly dispersed; when the pollution levels of the wastewater entering the equalization tank twice differ greatly, such as the first wastewater entering the equalization tank having a lower pollution level and the second wastewater having a higher pollution level, the deflector plate can be opened to allow the two wastewaters to mix first. Then, during the continued introduction of the second wastewater, the two separation tanks will gradually become one with a higher pollution level and the other with a lower pollution level, ensuring the smooth operation of subsequent treatment devices; The normal discharge process is as follows: Wastewater discharged from the transmission pipe combines with flocculant and then enters the dissolved air flotation module for treatment, thus completing the three-stage treatment of wastewater. Large-volume sediments settle at the bottom of the dissolved air flotation module, awaiting subsequent discharge, while small-volume particles move upward under the action of air flotation and float on the water surface. After the conveyor belt runs continuously, the belt moves around the top surface once and then moves to the bottom, causing the large-volume fibers isolated on the top surface to fall under the action of gravity. In this way, the conveyor belt can continuously isolate large-volume fibers. Through this setting, not only is a multi-stage treatment effect of wastewater achieved, but it is also effectively adapted to the treatment process of multiple batches of different textile wastewater.

[0010] Preferably, a cleaning box is provided below the end of the conveyor belt, and the top of the cleaning box is open. Multiple flat baffles are fixed to the conveyor belt. The cleaning box can receive large-volume fibers that slide outward from the end of the conveyor belt. Pneumatic equipment can be installed inside the cleaning box to blow air to the bottom of the conveyor belt to assist the fiber shedding process. At the same time, the bottom of the conveyor belt will move to the top of the dissolved air flotation module. The baffles on the surface of the belt can clean the debris floating on the surface of the dissolved air flotation module to one side, thereby ensuring the long-term working effect of the dissolved air flotation module.

[0011] Preferably, the highest points of the multiple connecting pipes are at different heights, and the connecting pipes are arranged in a bent shape. A reduction motor for controlling the rotation of the deflection plate is installed at the bottom of the regulating tank. The top of the deflection plate is rotatably connected to the regulating tank via a bracket at one end. When the wastewater flow rate is large, the water level in the regulating tank will gradually rise. Due to the different heights of the multiple connecting pipes, the flow efficiency between the two separation tanks will be higher as the water level rises. Furthermore, because the connecting pipes are in a bent shape, water can be introduced into another separation tank from the middle of the separation tank, thereby avoiding bottom sedimentation and top floating, and ensuring that the wastewater pollution rate in the other separation tank is low.

[0012] Preferably, the surface of the stirring platform is provided with multiple drain valves II from top to bottom, the bottom of the regulating tank is fixedly connected to drain valve I, the bottom of the stirring platform is provided with a one-way pipe, the bottom of the stirring platform is fixedly connected to a round pipe, the round pipe is rotatably connected to the top of the one-way pipe, drain valve I is connected to the one-way pipe, a mixing detection pipe is connected between two one-way pipes, and the mixing detection pipe is connected to the transmission pipe. Multiple drain valves II can transfer wastewater from different levels of wastewater, with the wastewater in the middle position having the least amount of pollutants. In this way, even in the separation tank in the high-pollution area, wastewater of the required concentration can be continuously removed as needed. The remaining high-pollution wastewater can wait for the next batch of low-pollution wastewater to mix before being discharged. Drain valve I can directly draw out wastewater from the bottom. The one-way pipes drain water in one direction only, without backflow. The mixing detection pipe is provided with a non-contact detection module, which can use an infrared light suspended solids detection module to detect the suspended solids content in the wastewater, thereby determining the degree of pollution.

[0013] Preferably, a drive motor is provided on both sides of the regulating tank. A transmission disc is fixedly connected to the output end of the drive motor and the outer side of the bottom circular tube of the stirring table. A transmission belt is sleeved between the two transmission discs. When the drive motor rotates, it drives one of the transmission discs to rotate, and then drives the other transmission disc to rotate through the transmission belt, thereby driving the circular tube and the stirring table to rotate. In this way, the stirring table can be rotated, and the wastewater can be discharged outward at the same time.

[0014] Preferably, two liquid pumps are fixed to the top of the regulating tank. The bottom of each liquid pump is equipped with a telescopic extension pipe. The output end of the liquid pump is horizontally outward and located above the conveyor belt. Floating matter in the wastewater in the separation tank can be absorbed by the extension pipe. The extension pipe can be extended downward according to the water level. The liquid pump is started to draw out part of the wastewater at the top, and the drawn wastewater is discharged onto the conveyor belt, which can filter the floating filter material again, thereby reducing the floating matter in the wastewater.

[0015] Preferably, the separation tank is equipped with a floating plate that can move up and down. The surface of the floating plate has multiple through holes. The four corners of the separation tank are rounded. The floating plate is located below the extension pipe. The floating plate changes with the water level. By periodically starting the stirring table, the water in the separation tank rotates. Floating objects on the water surface are blocked when they pass by the floating plate. In this way, even if the extension pipe only absorbs in one place, all floating objects can be cleaned up.

[0016] Preferably, the separation tank is provided with two vertical moving rails, and both ends of the float are slidably engaged with the moving rails. The moving rails allow the float to slide stably up and down.

[0017] Preferably, the interior of the float plate is hollow, and a flat float block is fixed to the middle of the float plate. The float block can provide buoyancy to the float plate, and the float block is located in the middle of the float plate, so that the middle of the float plate is on the water surface, which can effectively block floating objects.

[0018] Preferably, a recovery box is fixedly connected to one end of the dissolved air flotation module. The top of the recovery box is open, and a friction strip is fixedly connected to the edge of the top surface of the recovery box. The movement of the conveyor belt will push the floating objects on the surface of the dissolved air flotation module into the recovery box. The friction strip can rub against the bottom of the conveyor belt to assist in the removal of the floating objects.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The high-efficiency and energy-saving textile wastewater treatment equipment of the present invention not only achieves multi-stage treatment of wastewater, but also effectively adapts to the treatment process of multiple batches of different textile wastewater. It can ensure that the pollution level of the wastewater injected into the treatment equipment is the same each time, allowing the subsequent treatment devices to work smoothly. It can also control the wastewater to be discharged into the subsequent equipment at a constant rate, reducing the problem of excessive load on the treatment device when the water volume is high.

[0021] 2. The high-efficiency and energy-saving textile wastewater treatment equipment of the present invention has a cleaning box that can receive large-volume fibers sliding outward from the end of the conveyor belt. The cleaning box can be equipped with pneumatic equipment to blow air to the bottom of the conveyor belt to assist the fiber shedding process. At the same time, the bottom of the conveyor belt will move to the top of the dissolved air flotation module. The baffle on the surface of the belt can clean the debris floating on the surface of the dissolved air flotation module to one side, thereby ensuring the long-term working effect of the dissolved air flotation module.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 7As shown in the figure, an efficient and energy-saving textile wastewater treatment device according to an embodiment of the present invention includes an equalization tank 1. A wastewater pipe 4 is provided at the upper rear end of the equalization tank 1. Two separation tanks 13 are opened inside the equalization tank 1. The two separation tanks 13 are connected by multiple connecting pipes 14. A rotating stirring table 18 is provided at the bottom inner side of the separation tank 13. Multiple fan blades 19 are fixed to the outer side of the stirring table 18. A dissolved air flotation module 8 is installed at the front end of the equalization tank 1. A conveyor belt 2 arranged in a ring is provided at the top outer side of the equalization tank 1. Multiple hollow holes are opened on the surface of the conveyor belt 2. Two rotating deflector plates 17 are installed between the two separation tanks 13. The equalization tank 1 and the dissolved air flotation module 8 are connected by a transmission pipe 11. A receiving cover 15 for receiving the water flow from the wastewater pipe 4 is provided below the conveyor belt 2. The receiving cover 15 is connected to one of the separation tanks 13.

[0033] The textile wastewater to be treated is discharged from top to bottom onto the conveyor belt 2 through the wastewater pipe 4. Due to the perforated surface of the conveyor belt 2, large impurities such as textile fibers in the wastewater are blocked above the conveyor belt 2. As the conveyor belt 2 moves continuously, it carries the impurities away from their original positions, thus continuously filtering out large impurities. The wastewater after primary filtration is received by the receiving hood 15 and injected into one of the separation tanks 13. As the wastewater accumulates in the separation tank 13, some of the wastewater will enter another separation tank 13 through the connecting pipe 14. The pollutants in textiles generally include floating matter and sediment; high-density pollutants settle, while low-density pollutants float. The connecting pipe 14 will draw water from the middle of the wastewater... Wastewater is transferred to another separation tank 13, while the intermediate wastewater contains less pollutant, resulting in different levels of contamination in the two separation tanks 13. The wastewater with varying levels of contamination is then discharged into the transfer pipe 11 at different rates. When the batch of wastewater is highly contaminated, the discharge rate from the low-contamination separation tank 13 is increased; conversely, when the batch is less contaminated, the discharge rate is decreased. This ensures that the mixed wastewater in the transfer pipe 11 maintains a consistent level of contamination and allows for controlled discharge at a constant rate into subsequent equipment, thus completing the secondary treatment of the wastewater. This setup guarantees that the wastewater injected into the transfer pipe 11 is consistently contaminated. The same level of pollution ensures smooth operation of subsequent treatment devices. When wastewater in the low-pollution separation tank 13 is consumed quickly, causing backflow, the stirring table 18 is activated to rotate, working in conjunction with the fan blades 19 to increase the stirring effect and ensure that the pollutants in the wastewater in both separation tanks 13 are evenly dispersed. When the pollution levels of the wastewater entering the equalization tank 1 differ significantly, such as the first wastewater entering the equalization tank 1 having a lower pollution level while the second wastewater entering has a higher pollution level, the deflection plate 17 can be opened to allow the two wastewaters to mix first. Then, during the continued introduction of the second wastewater, the two separation tanks 13 will gradually become one with a higher pollution level and the other with a lower pollution level. To ensure proper subsequent discharge, the wastewater discharged through the transmission pipe 11 combines with the flocculant and then enters the dissolved air flotation module 8 for further treatment, thus completing the three-stage treatment of the wastewater. Large-volume sediments settle at the bottom of the dissolved air flotation module 8, awaiting subsequent discharge, while small-volume particles move upwards under the action of air flotation and float on the water surface. After continuous operation, the conveyor belt 2 moves around the top surface once and then moves to the bottom, causing the large-volume fibers isolated on the top surface to fall under the action of gravity. In this way, the conveyor belt 2 can continuously isolate large-volume fibers. Through this setting, not only is a multi-stage treatment effect of wastewater achieved, but it also effectively adapts to the treatment process of multiple batches of different textile wastewater.

[0034] A cleaning box 6 is provided below the end of the conveyor belt 2. The top of the cleaning box 6 is open. Multiple flat partitions 3 are fixed to the belt of the conveyor belt 2.

[0035] During operation, the cleaning box 6 can receive large-volume fibers that slide outward from the end of the conveyor belt 2. Pneumatic equipment can be installed inside the cleaning box 6 to blow air to the bottom of the conveyor belt 2 to assist the fiber shedding process. At the same time, the bottom of the conveyor belt 2 will move above the dissolved air flotation module 8. The partition 3 on the surface of the belt can clean the debris floating on the surface of the dissolved air flotation module 8 to one side, thereby ensuring the long-term working effect of the dissolved air flotation module 8.

[0036] The highest points of the multiple connecting pipes 14 are at different heights. The connecting pipes 14 are arranged in a bent shape. A reduction motor for controlling the rotation of the deflection plate 17 is installed at the bottom of the regulating pool 1. The top of the deflection plate 17 is rotatably connected to the regulating pool 1 via a bracket at one end.

[0037] During operation, when the wastewater flow rate is large, the water level in the equalization tank 1 will gradually rise. Due to the different heights of the multiple connecting pipes 14, the flow efficiency between the two separation tanks 13 will be higher as the water level rises. Furthermore, since the connecting pipes 14 are in a bend, water can be introduced into another separation tank 13 from the middle of the separation tank 13, thereby avoiding bottom sedimentation and top floating, and ensuring that the wastewater pollution rate in the other separation tank 13 is low.

[0038] The surface of the mixing platform 18 is provided with multiple drain valves 25 from top to bottom. The bottom of the regulating tank 1 is fixedly connected to a drain valve 22. The bottom of the mixing platform 18 is provided with a one-way pipe 24. The bottom of the mixing platform 18 is fixedly connected to a round pipe. The round pipe is rotatably connected to the top of the one-way pipe 24. The drain valve 22 is connected to the one-way pipe 24. A mixing detection pipe 12 is connected between the two one-way pipes 24. The mixing detection pipe 12 is connected to the transmission pipe 11.

[0039] During operation, multiple drain valves 25 can transfer wastewater from different levels of the wastewater. The wastewater in the middle position has the fewest pollutants. This way, even in the separation tank 13 in the high-pollution area, wastewater of the required concentration can be continuously removed as needed. The remaining high-pollution wastewater can wait for the next batch of low-pollution wastewater to mix before being discharged. Drain valve 22 can directly draw out the wastewater from the bottom. The one-way pipes 24 drain water in one direction only, without backflow. The mixing detection pipe 12 is equipped with a non-contact detection module, which can use an infrared light suspended solids detection module to detect the suspended solids content in the wastewater to determine the degree of pollution.

[0040] Both sides of the regulating tank 1 are equipped with drive motors 7. The output end of the drive motor 7 and the outer side of the bottom round tube of the stirring table 18 are both fixed with transmission discs. A transmission belt 23 is sleeved between the two transmission discs.

[0041] During operation, the drive motor 7 rotates, which drives one of the transmission discs to rotate. The transmission belt 23 then drives the other transmission disc to rotate, which in turn drives the round pipe and the mixing table 18 to rotate. This allows the mixing table 18 to rotate while simultaneously allowing wastewater to be discharged.

[0042] Two liquid pumps 5 are fixed to the top of the regulating tank 1. The bottom of the liquid pump 5 is equipped with a telescopic extension pipe 16. The output end of the liquid pump 5 is set horizontally outward and is located above the conveyor belt 2.

[0043] During operation, the floating matter in the wastewater in the separation tank 13 can be absorbed by the extension pipe 16. The extension pipe 16 can be extended downward according to the water level. The liquid pump 5 is started to pump out the waste liquid at the top. The pumped waste liquid is discharged onto the conveyor belt 2, which can filter the floating filter material again, thereby reducing the floating matter in the wastewater.

[0044] The separation groove 13 is provided with a floating plate 21 that can move up and down. The surface of the floating plate 21 is provided with multiple through holes. The four corners of the separation groove 13 are rounded. The floating plate 21 is located below the extension tube 16.

[0045] During operation, the float plate 21 changes with the water level. The periodic activation of the stirring table 18 causes the water in the separation tank 13 to rotate. Floating objects on the water surface are blocked when they pass by the float plate 21. In this way, even if the extension pipe 16 only absorbs in one place, all floating objects can be cleaned up.

[0046] The separation tank 13 is equipped with two moving rails 20, which are arranged vertically. Both ends of the float 21 are slidably engaged with the moving rails 20. During operation, the moving rails 20 allow the float 21 to slide stably up and down.

[0047] The interior of the float plate 21 is hollow, and a flat float block is fixed to the middle of the float plate 21;

[0048] When in operation, the float can provide buoyancy to the float plate 21, and the float is located in the middle of the float plate 21, so that the middle of the float plate 21 is on the water surface, which can effectively block floating objects.

[0049] One end of the dissolved air flotation module 8 is fixedly connected to a recovery box 9. The top of the recovery box 9 is open, and a friction strip is fixedly connected to the edge of the top surface of the recovery box 9.

[0050] During operation, the movement of the conveyor belt 2 pushes the floating objects on the surface of the dissolved air flotation module 8 into the recycling bin 9. The friction strips can rub against the bottom of the conveyor belt 2 to assist in the removal of the floating objects.

[0051] During operation, the textile wastewater to be treated is discharged from top to bottom onto the conveyor belt 2 through the wastewater pipe 4. Due to the perforated surface of the conveyor belt 2, large impurities such as textile fibers in the wastewater are blocked above the conveyor belt 2. As the conveyor belt 2 moves continuously, it carries the impurities away from their original positions, thus continuously filtering out large impurities. The wastewater after primary filtration is received by the receiving hood 15 and injected into one of the separation tanks 13. As the wastewater accumulates in the separation tank 13, some of the wastewater will enter another separation tank 13 through the connecting pipe 14. The pollutants in textiles generally include floating matter and sediment; high-density pollutants settle, while low-density pollutants float. The connecting pipe 14 will draw water from the middle of the wastewater... The wastewater is transferred to another separation tank 13, while the intermediate wastewater contains less pollutant, resulting in different levels of contamination in the two separation tanks 13. The wastewater with different levels of contamination is then discharged into the transfer pipe 11 at different rates. When the batch of wastewater is highly contaminated, the discharge rate in the low-contamination separation tank 13 is increased; when the batch is less contaminated, the discharge rate in the low-contamination separation tank 13 is decreased. This ensures that the mixed wastewater in the transfer pipe 11 always maintains a consistent level of contamination and allows for controlled discharge at a constant rate into subsequent equipment, thus completing the secondary treatment of the wastewater. This setup ensures that the wastewater injected into the transfer pipe 11 each time is of a consistent level of contamination. The same level of pollution allows subsequent treatment devices to operate smoothly. When wastewater in the low-pollution separation tank 13 is consumed quickly and backflow occurs, the stirring table 18 is activated to rotate, and the fan blades 19 are used to increase the stirring effect, ensuring that the pollutants in the wastewater in the two separation tanks 13 are evenly dispersed. When the pollution levels of the wastewater entering the equalization tank 1 differ greatly, such as the first wastewater entering the equalization tank 1 having a lower pollution level and the second wastewater having a higher pollution level, the deflector plate 17 can be opened to allow the two wastewaters to mix first. Then, during the continued introduction of the second wastewater, the two separation tanks 13 will gradually become one with a higher pollution level and the other with a lower pollution level. This ensures the normal discharge process afterwards. The wastewater discharged from the transmission pipe 11 will combine with the flocculant and then enter the dissolved air flotation module 8 for treatment, thus completing the three-stage treatment of the wastewater. Large-volume sediments will settle from the bottom of the dissolved air flotation module 8 and wait for subsequent discharge, while small-volume particles will move upward under the action of air flotation and float on the water surface. After the conveyor belt 2 runs continuously, the belt will move around the top surface once and then transfer to the bottom, so that the large-volume fibers isolated on the top surface fall down under the action of gravity. In this way, the conveyor belt 2 can continuously isolate large-volume fibers. Through this setting, not only is the multi-stage treatment effect of wastewater achieved, but it can also effectively adapt to the treatment process of multiple batches of different textile wastewater.

[0052] The cleaning box 6 can receive large-volume fibers that slide outward from the end of the conveyor belt 2. Pneumatic equipment can be installed inside the cleaning box 6 to blow air to the bottom of the conveyor belt 2 to assist the fiber shedding process. At the same time, the bottom of the conveyor belt 2 will move to the top of the dissolved air flotation module 8. The partition 3 on the surface of the belt can clean the debris floating on the surface of the dissolved air flotation module 8 to one side, thereby ensuring the long-term working effect of the dissolved air flotation module 8.

[0053] When the wastewater flow rate is large, the water level in the equalization tank 1 will gradually rise. Since the multiple connecting pipes 14 have different heights, the flow efficiency between the two separation tanks 13 will be higher as the water level rises. Furthermore, since the connecting pipes 14 are in a bend, water can be introduced into another separation tank 13 from the middle of the separation tank 13, thereby avoiding bottom sedimentation and top floating, and ensuring that the wastewater pollution rate in the other separation tank 13 is low.

[0054] Multiple drain valves 25 can transfer wastewater from different levels of wastewater, with the wastewater in the middle having the fewest pollutants. This allows wastewater of the required concentration to be continuously removed even in the separation tank 13, which is in a high-pollution area. The remaining high-pollution wastewater can be discharged after being mixed with the next batch of low-pollution wastewater. Drain valve 22 can directly draw out wastewater from the bottom. The one-way pipes 24 drain water in one direction only, preventing backflow. The mixing detection pipe 12 is equipped with a non-contact detection module, which can use an infrared suspended solids detection module to detect the suspended solids content in the wastewater to determine the degree of pollution.

[0055] The drive motor 7 rotates, which drives one of the transmission discs to rotate. The transmission belt 23 then drives the other transmission disc to rotate, which in turn drives the round pipe and the mixing table 18 to rotate. This allows the mixing table 18 to rotate while simultaneously allowing wastewater to be discharged.

[0056] The floating matter in the wastewater in the separation tank 13 can be absorbed by the extension pipe 16. The extension pipe 16 can be extended downward according to the water level. The liquid pump 5 is started to pump out the waste liquid at the top. The pumped waste liquid is discharged onto the conveyor belt 2, which can filter the floating filter material again, thereby reducing the floating matter in the wastewater.

[0057] The float plate 21 changes with the water level. The periodic activation of the stirring table 18 causes the water in the separation tank 13 to rotate. Floating objects on the water surface are blocked when they pass by the float plate 21. In this way, even if the extension pipe 16 only absorbs in one place, all the floating objects can be cleaned up.

[0058] The float can provide buoyancy to the float plate 21, and the float is located in the middle of the float plate 21, so that the middle of the float plate 21 is on the water surface, which can effectively block floating objects.

[0059] The movement of conveyor belt 2 will push the floating objects on the surface of dissolved air flotation module 8 into the recycling bin 9. The friction strips can rub against the bottom of conveyor belt 2 to assist in the removal.

The round pipe is rotatably connected to the top of the one-way pipe. The drain valve 1 is connected to the one-way pipe. A mixing detection pipe is connected between the two one-way pipes. The mixing detection pipe is connected to the transmission pipe. The textile wastewater that needs to be treated is discharged from top to bottom onto the conveyor belt through the wastewater pipe. The wastewater after primary filtration is received by the receiving hood and injected into one of the separation tanks. As the wastewater accumulates in the separation tank, some of the wastewater will enter another separation tank through the connecting pipe. Then, wastewater with different levels of pollution is discharged into the transmission pipe at different rates. The mixed wastewater in the transmission pipe is always at the same level of pollution. The wastewater is controlled to be discharged into the subsequent equipment at a constant rate, thereby completing the secondary treatment of the wastewater.
