[0002] In the production process of the printing and dyeing industry, a large amount of printing and dyeing wastewater containing various pollutants will be generated. If these wastewaters are directly discharged without effective treatment, they will cause serious damage to the ecological environment, such as polluting water bodies and affecting soil quality. Traditional printing and dyeing wastewater treatment devices lack the ability to treat wastewater at multiple levels, making it difficult to comprehensively and efficiently remove various pollutants in wastewater. For example, large particles of impurities cannot be effectively intercepted in the early stage, which can easily cause blockage and other adverse effects on subsequent treatment links; some cannot accurately supplement reagents as needed during the treatment process to promote purification reactions, resulting in unstable treatment effects; others cannot monitor water quality parameters in real time and cannot adjust the treatment process in time, making it difficult for wastewater to meet standards for stable discharge; and after the wastewater is precipitated, there is a lack of a mechanism that can flexibly separate clean water according to the height of the water flow, and the treatment device requires a large occupied area and lacks integrated functions. Therefore, there is an urgent need for a treatment and detection device that can overcome the above problems, has multi-level treatment functions, and cooperates with each link to effectively ensure that printing and dyeing wastewater meets discharge standards.

[0019] Example 1

[0020] like Figures 1 to 8As shown, the embodiment of the present application provides a multi-stage printing and dyeing wastewater treatment detection device, including a treatment tank 10 and a grille filter tank 20, the grille filter tank 20 is located in the treatment tank 10, and the water inlet of the treatment tank 10 is connected to the grille filter tank 20; it also includes: a reagent replenishing mechanism 40, a clean water discharge mechanism 50, an aeration mechanism 60, and a detection mechanism 70; The delivery end of the reagent replenishing mechanism 40 is connected to the inner cavity of the treatment tank 10; the clean water discharge mechanism 50 is arranged in the inner cavity of the treatment tank 10 so as to float along with the water flow height, and is used to suck out the surface clean water generated after the sedimentation; the aeration mechanism 60 is arranged at the bottom of the treatment tank 10; the detection mechanism 70 is arranged on the grille filter tank 20 and the inner wall of the treatment tank 10, and the part of the detection mechanism 70 located on the inner wall of the treatment tank 10 is used to detect the water level height, and the part of the detection mechanism 70 located on the grille filter tank 20 is used to detect the water quality parameters entering the treatment tank; The reagent replenishing mechanism 40 provided in the present application is fixed in the inner cavity of the treatment tank 10, and the reagents required for treating printing and dyeing wastewater can be added to the treatment tank 10 as needed to promote the wastewater purification reaction; the clean water discharge mechanism 50 can float according to the water flow height in the treatment tank 10, and when the surface clean water is precipitated, it can suck out the clean water to achieve the separation of the clean water and the wastewater being treated; the aeration mechanism 60 is placed at the bottom of the treatment tank 10, and the wastewater is fully contacted with the air through aeration, so as to enhance the dissolved oxygen content in the water, which is beneficial to the oxidation and decomposition of pollutants such as organic matter in the wastewater; the detection mechanism 70 is arranged on the grille filter tank 20 and the inner wall of the treatment tank 10, and can monitor the wastewater quality parameters at each stage, such as the concentration of pollutants, in real time, so as to adjust the treatment process in time; the grille tank 22 in the grille filter tank 20 can preliminarily intercept large particles of impurities in the wastewater.

[0021] Among them, the grille filter tank 20 includes a grille pool 22, and a cleaning component 23 is arranged in the grille pool 22. The cleaning component 23 is used to automatically and periodically clean the grille part of the grille pool 22 to prevent the grille from being blocked and affecting the filtering efficiency. When working, the printing and dyeing wastewater first enters the grille filter tank 20, the grille pool 22 intercepts large particles of impurities, and the cleaning component 23 regularly cleans the grille. Then the wastewater enters the treatment tank 10, the reagent replenishing mechanism 40 adds reagents as needed, the aeration mechanism 60 aerates to promote treatment, and the detection mechanism 70 monitors the water quality. The precipitation generated during the treatment process makes the clean water located on the surface, and the clean water discharge mechanism 50 sucks it out. Through the above-mentioned multi-stage treatment process, it is ensured that the treated wastewater meets the discharge standards.

[0022] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in some examples, further, the treatment tank 10 includes: an inlet pipe 11, a sewage pipe 12 and a sealing top plate 13, the inlet pipe 11 is connected to one end of the treatment tank 10, and the inlet pipe 11 extends into the inner cavity of the grid tank 22; one end of the sewage pipe 12 is connected to the lowest point in the center of the bottom end of the treatment tank 10, and the other end extends to the outside of the treatment tank 10; the sealing top plate 13 can be opened and closed in the top opening of the treatment tank 10, and can seal the treatment tank 10.

[0023] In this example, the water inlet pipe 11 is connected to one end of the treatment tank 10 and extends to the inner cavity of the grille tank 22. Its function is to guide the printing and dyeing wastewater into the grille tank 22, thereby starting the wastewater treatment process. The sewage pipe 12 is connected to the lowest point of the bottom center of the treatment tank 10. The impurities, sludge and other wastes precipitated at the bottom of the treatment tank 10 can be discharged through the sewage pipe 12 to prevent their accumulation from affecting the treatment effect. The sealing top plate 13 can be opened and closed in the top opening of the treatment tank 10 and can seal the treatment tank 10. When it is necessary to create an anaerobic environment, the sealing top plate 13 is closed to form an anaerobic environment in the treatment tank 10, which is conducive to the corresponding treatment reaction of specific pollutants in the wastewater under anaerobic conditions. When it is necessary to inspect and repair the inside of the treatment tank 10, add materials, etc., the sealing top plate 13 can be opened to form an aerobic environment, and cooperate with aeration and biologically activated sludge to carry out the corresponding biological treatment process to meet the multi-process and multi-stage water treatment requirements. During the specific implementation process, printing and dyeing wastewater enters the grille pool 22 through the water inlet pipe 11, and enters the treatment pool 10 after pre-treatment such as grille filtration. Waste such as precipitation generated during the treatment is discharged through the sewage pipe 12. The sealing top plate 13 is opened and closed as needed to create an anaerobic environment or an aerobic environment to optimize different water treatment conditions.

[0024] It should also be noted that the sealing top plate 13 can be further configured as a folding sealing plate 132, and the folding sealing plates 132 are arranged in two groups opposite to each other, and can be folded and opened from the middle of the treatment pool 10 to the edge of the treatment pool 10, or laid on the top of the treatment pool 10, and multiple folding sealing plates 132 are arranged in the top frame 131 of the treatment pool 10 (such as Figure 3 as shown).

[0025] like Figure 3 and Figure 4 As shown, in some examples, further, the grille filter tank 20 includes: a guide tank 21, a grille tank 22, a cleaning component 23 and a dirt collection tank 24, the guide tank 21 is fixedly arranged on one side of the upper half of the treatment tank 10, and the end of the water inlet pipe 11 is located in the guide tank 21; the grille tank 22 is located in the guide tank 21, and a strip drain is arranged below the guide tank 21 for changing the width of the water flow acting on the grille tank 22; the dirt collection tank 24 is adjacent to the grille tank 22, for collecting the dirt generated by the cleaning component 23 when cleaning the grille tank 22.

[0026] In this example, the guide pool 21 is fixed to one side of the upper half of the treatment pool 10, and the end of the water inlet pipe 11 is located therein. Its function is to guide the printing and dyeing wastewater into the device for treatment. The guide pool 21 allows the wastewater to flow into the subsequent grid pool 22 evenly and stably to avoid excessive water flow impact or uneven distribution affecting the filtration effect; the grid pool 22 is located in the guide pool 21, and the width of the water flow acting on it is changed through the strip drain port, so that the water flow flows through the grid evenly and dispersedly, effectively intercepting large particles of impurities and other pollutants in the wastewater, and ensuring that the impurity content of the wastewater entering the subsequent links of the treatment pool 10 is within a reasonable range; the cleaning component 23 automatically and periodically cleans the grid pool 22 to prevent the grid from being blocked by dirt and affecting the filtration efficiency and the wastewater treatment process; the dirt collection pool 24 is adjacent to the grid pool 22, and is specifically used to collect the dirt generated when the cleaning component 23 cleans the grid pool 22, so as to facilitate centralized treatment of the dirt and avoid it from being mixed into the wastewater treatment process again.

[0027] In the specific working process of this example, the printing and dyeing wastewater enters the guide pool 21 through the water inlet pipe 11, and after being guided, it flows evenly to the grille pool 22 through the strip drain port. The grille pool 22 filters impurities, and the cleaning component 23 cleans the grille regularly. The cleaned dirt falls into the dirt collection pool 24, so that the printing and dyeing wastewater can efficiently remove large particles of impurities in the pretreatment stage, thereby improving the reliability of the entire wastewater treatment, reducing the burden of subsequent treatment links, and improving the water quality compliance rate after treatment.

[0028] like Figure 4 As shown, in some examples, further, the grille pool 22 is further provided with: a waste outlet 221, a movable hole 222, a filter grille front section 223 and a filter grille rear section 224, and the waste outlet 221 is strip-shaped and opened on the left outer wall of the grille pool 22 (such as Figure 6 As shown), and corresponds to the position of the dirt collection pool 24; the front section 223 of the filter grille is arranged in the bottom wall of the grille pool 22 on one side of the guide pool 21; the rear section 224 of the filter grille is arranged in the bottom wall of the grille pool 22 on one side of the dirt outlet 221, and the movable hole 222 penetrates the side wall of the grille pool 22 opened above the rear section 224 of the filter grille; the cleaning component 23 penetrates the movable hole 222.

[0029] In this example, the front section 223 of the filter grille is arranged in the bottom wall of the grille pool 22 on one side of the guide pool 21, which can provide a large area of ​​filtration working area to efficiently purify the wastewater; the rear section 224 of the filter grille is arranged in the bottom wall of the grille pool 22 on one side of the dirt outlet 221, serving as the tail end of the overall filter grille; in the conventional grille treatment process, if the filtering performance of the overall filter grille is saturated (when too much dirt is attached), the excess dirt will be washed to the tail end of the grille, in order to improve the filtering effect and avoid excessive dirt attachment; the dirt outlet 221 is opened in the shape of a strip in the grille pool 22 away from the outer wall of the guide pool 21 and corresponds to the dirt collection pool 24, so that when the cleaning component 23 cleans the grille, the intercepted dirt is pushed to the dirt collection pool 24 through the dirt outlet 221; the movable hole 222 runs through the filter grille The side wall of the grille pool 22 above the rear section 224 provides a movable through-channel for the cleaning component 23. A pleated flexible sealing layer is arranged in the through-channel. The center position of the flexible sealing layer wraps around the cleaning component located in the through-channel, and the outer end of the flexible sealing layer is sealed and connected to the inner wall around the movable hole, so that the cleaning component 23 can move freely in the grille pool 22, while maintaining the sealing effect of the movable hole 222 to prevent impurities from leaking from the movable hole 222, thereby achieving efficient cleaning of the rear section 224 of the filter grille; the cleaning component 23 cleans the rear section 224 of the filter grille, and pushes the dirt intercepted on the surface of the grille to the dirt outlet 221, so that it falls into the dirt collection pool 24, thereby ensuring that the filtering function of the grille pool 22 for printing and dyeing wastewater is continuously effective, avoiding clogging of the grille due to dirt accumulation, and ensuring that the wastewater enters the subsequent treatment link stably and efficiently.

[0030] It is worth mentioning that the front section 223 of the filter grille and the rear section 224 of the filter grille in this example can be made of different materials, but the filter holes can have the same aperture. For example, the material of the rear section 224 of the filter grille is stainless steel to improve its material strength. In the face of long-term cleaning contact of the cleaning mechanism, it has a longer service life and is not easy to deform.

[0031] like Figure 4 and Figure 5As shown, in some examples, further, the cleaning component 23 includes: two first rotating rods 231, two push rods 232, two second rotating rods 233, two bent plates 234, a push plate 235 and a power unit 236, one end of each first rotating rod 231 can be rotatably set on the inner wall of the treatment tank 10, and corresponds to the position of the grille filter tank 20; the two push rods 232 are respectively rotatably connected to the other end of the first rotating rod 231, and the push rods 232 are bent; one end of each second rotating rod 233 can be rotatably set on the inner wall of the treatment tank 10, and the other end of the second rotating rod 233 can be rotatably connected to the middle of the push rod 232; the two bent plates 234 are respectively arranged below the end of each push rod 232 close to the dirt outlet 221; the push plate 235 can be detachably set on the inner side of the two bent plates 234, and can contact the upper end surface of the rear section 224 of the filter grille; the power unit 236 is transmission-connected to the first rotating rod 231.

[0032] In this example, specifically, two first rotating rods 231 are placed on the inner wall of the treatment tank 10 and correspond to the grille filter tank 20, providing basic rotation support and positioning for the cleaning assembly 23, which rotates under the drive of the power unit 236, driving the entire cleaning assembly 23 to move. The two bent push rods 232 located on both sides of the grille filter tank 20 are respectively rotatably connected to the other end of the first rotating rod 231, and their bent shape is conducive to flexible movement in the grille tank 22 and changing the movement trajectory of the push plate 235. One end of the two second rotating rods 233 is rotatably set on the inner wall of the treatment tank 10, and the other end is connected to the middle part of the push rod 232, which enhances the stability and flexibility of the rotation of the push rod 232 and makes its movement trajectory more precise. The two bent plates 234 are respectively placed below the end of the push rod 232 close to the dirt outlet 221, and face the grille below. The push plate 235 is detachably arranged on the inner side of the bending plate 234 and can contact the upper end surface of the filter grid rear section 224. Driven by the rotation of the first rotating rod 231 and restricted by the rotation of the second rotating rod 233, the push plate 235 moves along the surface of the filter grid rear section 224 to push the dirt intercepted on the grid toward the dirt outlet 221. The power unit 236 is connected to the first rotating rod 231 in a transmission manner to provide power for the entire cleaning assembly 23 so that it can automatically operate periodically, for example, by using a motor or other rotating power providing components.

[0033] When the present example is working, the power unit 236 drives the first rotating rod 231 to rotate, driving the push rod 232 to move, thereby causing the push plate 235 to translate on the surface of the filter grille rear section 224 in the direction of the water flow to clean the dirt. After passing through the filter grille rear section 224, the first rotating rod 231 rotates to a position below its rotation axis, and under the limitation of the second rotating rod 233, the push plate 235 is lifted and returns to the initial position, avoiding the situation where the push rod 232 always moves back and forth, and avoiding the accumulated dirt that will continue to be generated during the return process to be pushed back to the front section of the filter grille plate. The push rod 232 assists in guiding the dirt to the dirt outlet 221, and the second rotating rod 233 ensures the stable movement of the push rod 232. Among them, the preferred configuration in this example is: the length of the first rotating rod 231 is 40 cm, the length of the second rotating rod 233 is 72 cm, the height between the rotation points of the first rotating rod 231 and the second rotating rod 233 is The height difference is 60cm, the horizontal spacing dimension between the first rotating rod 231 and the second rotating rod 233 is 96cm, the length of one section of the push rod 232 close to the water inlet side is 100cm, and the length of the other section is 92cm, the angle between the first section and the second section is 159 degrees, the length of the bending plate 234 is 36cm, and the push plate 235 can be removed from the bottom end of the bending plate 234. When it needs to be removed, you can wait until the bending plate 234 runs to the highest point. The bottom end of the push plate 235 protrudes from the bottom end of the bending plate 234. In this way, the first rotating rod 231 and the second rotating rod 233 work together to achieve automatic and efficient cleaning of the filter grille of the grille pool 22, prevent the grille from being blocked, and ensure that the wastewater continuously and stably passes through the grille pool 22 to enter the subsequent treatment process, thereby improving the reliability and treatment efficiency of the printing and dyeing wastewater treatment system and reducing the manpower cost and time cost of manually cleaning the grille.

[0034] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in some examples, further, the power unit 236 includes: at least one speed transmission box 2361, two rotating seats 2362 and a plurality of force-bearing plates 2363, at least one speed transmission box 2361 is fixedly mounted on the outer wall of the treatment pool 10, and the speed transmission box 2361 includes a power input end and a power output end; the two rotating seats 2362 are rotatably arranged on the inner walls on both sides of the guide pool 21, and are located below the strip drain outlet of the guide pool 21; a plurality of force-bearing plates 2363 are equidistantly arranged between the two rotating seats 2362 along the circumferential direction; wherein the rotating shaft of the rotating seat 2362 is connected to the power input end of the speed transmission box 2361, and the power output end of the speed transmission box 2361 is connected to the first rotating rod 231.

[0035] In this example, the speed transmission box 2361 is fixed to the outer wall of the treatment pool 10, and its power input end is connected to the rotating shaft of the rotating seat 2362, and the power output end is connected to the first rotating rod 231, which can change the power transmission speed and torque, so that the rotation of the rotating seat 2362 can drive the first rotating rod 231 at a suitable speed and strength, thereby accurately controlling the movement speed and strength of the cleaning component 23 to meet different cleaning needs; the two rotating seats 2362 are respectively rotatably arranged on the inner walls on both sides of the guide pool 21 and are located below the strip drain outlet, providing an installation and rotation basis for multiple force-bearing plates 2363. When wastewater flows through the strip drain outlet of the guide pool 21, the water flow impacts the force-bearing plates 2363, causing the rotating seat 2362 to rotate, converting the kinetic energy of the water flow into the mechanical energy of the rotating seat 2362; multiple force-bearing plates 2363 are equidistantly arranged between the two rotating seats 2362 along the circumferential direction, increasing the contact area with the water flow, improving the collection efficiency of the kinetic energy of the water flow, and ensuring that there is sufficient power to drive the rotating seat 2362 to rotate.

[0036] When this example is working, the printing and dyeing wastewater flows out through the strip drain outlet of the guide pool 21 and impacts the force-bearing plate 2363, and the rotating seat 2362 rotates accordingly, and its rotating shaft transmits power to the speed transmission box 2361. Since the cleaning force generated by the gravitational potential energy of the water flow is small but can provide the rotating seat 2362 with the effect of high-speed rotation, the speed transmission box 2361 adjusts the high speed to a low speed and increases the torque at the same time. The first rotating rod 231 is driven to rotate through the adjusted power, thereby driving the cleaning component 23 to clean the grille pool 22. This example uses the gravitational potential energy of the water flow of the printing and dyeing wastewater itself to realize the automatic driving of the cleaning component 23, without the need for additional electricity or power source, thereby reducing operating costs and improving energy utilization. At the same time, it ensures the stable periodic operation of the cleaning component 23, maintains the normal filtering function of the grille pool 22, promotes the efficient and continuous operation of the entire printing and dyeing wastewater treatment system, and improves the economy and stability of the system.

[0038] In this example, the decolorant tank 41 is used to store decolorants, which can remove the pigments in the printing and dyeing wastewater and make the wastewater lighter in color; the solvent stored in the pH value adjustment solvent tank 42 can adjust the pH value of the wastewater in the treatment tank 10, create a suitable acid-base environment for the subsequent biological reaction tank treatment, and avoid the water body from being alkaline; the flocculant in the flocculant tank 43 can cause the tiny particles in the wastewater to aggregate to form larger flocs, which is convenient for precipitation and separation; the metering pump 44 is respectively installed on the decolorant tank 41, the pH value adjustment solvent tank 42 and the flocculant tank 43, and its function is to accurately control the addition amount of various agents to ensure the treatment effect and avoid agent waste; the output pipe transports the agent from the tank to the inner cavity of the treatment tank 10, and the one-way valve 45 This prevents the liquid in the treatment tank 10 from flowing back into the box; the detection mechanism 70 monitors the water quality parameters in the treatment tank 10 and the grid filter tank 20, such as the color, pH, impurity content, etc. of the wastewater, and transmits the signal to the controller of the metering pump 44; when the detected water quality parameters deviate from the preset standard, the controller controls the corresponding metering pump 44 to work according to the signal, and adds the decolorizing agent, pH adjusting solvent or flocculant to the treatment tank 10 as needed; therefore, this example can automatically and accurately replenish the reagents according to the real-time water quality conditions, ensure that all conditions in the treatment process are stable and appropriate, improve the efficiency and quality of printing and dyeing wastewater treatment, reduce the risk of treatment failure due to improper addition of reagents, and make the treated wastewater easier to meet the discharge standards.

[0039] like Figure 1 and Figure 3 As shown, in some examples, further, the stirring mechanism 30 includes a driving motor 31 fixed on the middle crossbeam at the top of the treatment tank 10, and a stirring shaft 32 is provided at the bottom output end of the driving motor 31. The stirring shaft 32 penetrates into the printing and dyeing wastewater. The purpose is that when the detected water quality parameters deviate from the preset standards, the controller controls the corresponding metering pump 44 to work according to the signal, and after the decolorizing agent, pH value adjusting solvent or flocculant is added to the treatment tank 10 as required, the stirring shaft 32 of the stirring mechanism 30 can better and more quickly stir the above-mentioned auxiliary agents evenly, thereby improving the reaction efficiency of the agents.

[0040] like Figure 3 , Figure 7 and Figure 8 As shown, in some examples, further, the clean water discharge mechanism 50 includes: a U-shaped pumping platform 51, at least one buoy 52, a plurality of back-suction cylinders 53 and a telescopic pipe 54. The U-shaped pumping platform 51 can be floated in the treatment tank 10. The U-shaped pumping platform 51 includes two straight pipelines, each of which is located on the bisector of the inner cavity of the treatment tank 10; at least one buoy 52 is fixedly connected to the inner side of the U-shaped pumping platform 51; a plurality of back-suction cylinders 53 are fixedly arranged at the bottom end of the U-shaped pumping platform 51; the back-suction main pipe 55 extends into the inner cavity of the treatment tank 10; the bottom end of the telescopic pipe 54 is connected to the U-shaped pumping platform 51, and the top end is connected to the back-suction main pipe 55.

[0041] In this example, the U-shaped pumping platform 51 can be floated in the treatment pool 10, and can float with the change of the water level in the treatment pool 10, ensuring that it is always in a suitable position to extract the surface clean water produced after sedimentation; at least one buoy 52 is fixedly connected to the inner side of the U-shaped pumping platform 51 to provide buoyancy support for the U-shaped pumping platform 51, so that it can stably float on the water surface and maintain a balanced state when extracting clean water; the function of multiple back-suction cylinders 53 is to suck in the surrounding clean water for subsequent collection and discharge; the bottom end of the telescopic tube 54 is connected to the U-shaped pumping platform 51, and the top end is connected to the back-suction main pipe 55, which can be flexibly extended and retracted according to the floating situation of the U-shaped pumping platform 51 to ensure the stability of the connection. The clean water sucked by the suction cylinder 53 is smoothly transmitted to the suction main pipe 55, and the suction main pipe 55 then guides the clean water out of the treatment tank 10; during operation, as the wastewater in the treatment tank 10 settles, the clean water is located on the surface, and the buoy 52 allows the U-shaped pumping platform 51 to float on the water surface, and the suction cylinder 53 sucks the surrounding clean water, and transmits it to the suction main pipe 55 through the telescopic tube 54, and finally discharges the clean water out of the treatment tank 10; this example can adapt to the water level changes in the treatment tank 10, efficiently and accurately extract and discharge the surface clean water after sedimentation, reduce the mixing of clean water and wastewater in the lower layer treatment, improve the efficiency and quality of clean water discharge, ensure the orderly operation of the entire printing and dyeing wastewater treatment, and facilitate the subsequent further utilization or discharge treatment of the discharged clean water.

[0042] like Figure 8 As shown, in some examples, further, the back-suction cylinder 53 includes: a plurality of cylinders 531, a water suction channel 532, a lifting frame 533, a filter screen 534, a spring 535 and a contact signal sensor 536, wherein the plurality of cylinders 531 are fixedly arranged at the bottom end of the straight pipeline at equal intervals in sequence; the water suction channel 532 is opened in the middle of the bottom end of the cylinder 531 and passes through the cylinder 531; the lifting frame 533 is arranged in the water suction channel 532 so as to be movable in lifting and lowering; the filter screen 534 is fixedly arranged in the lifting frame 533; the spring 535 is arranged in the water suction channel 532, and the bottom end of the spring 535 abuts against the upper end surface of the lifting frame 533; the contact signal sensor 536 is arranged on the inner wall of the water suction channel 532, the contact signal sensor 536 is located above the lifting frame 533, and a plurality of contacts 537 are arranged at the bottom end of the contact signal sensor 536, and the signal of the contact signal sensor 536 is connected to an external sewage pump.

[0043] In this example, multiple cylinders 531 are fixed at equal intervals at the bottom of the straight pipeline in sequence to form a back-suction channel for back-suctioning clean water; the water suction channel 532 is opened in the middle of the bottom end of the cylinder 531 and penetrates the cylinder 531, which is the entrance for clean water to enter the cylinder 531, so as to facilitate the suction of surface clean water after precipitation in the treatment tank 10; the lifting frame 533 can be lifted and lowered in the water suction channel 532, and can flexibly adjust its position according to the water suction situation and the impurity situation in the water to ensure smooth clean water suction; the filter screen 534 is fixedly placed in the lifting frame 533, The spring 535 is arranged in the water absorption channel 532, and its bottom end abuts against the upper end surface of the lifting frame 533, providing elastic support force for the lifting frame 533, so that the lifting frame 533 can move up and down adaptively when encountering different water flow pressures, impurity obstruction, etc., to maintain normal water absorption and filtering functions. When too many impurities are blocked on the filter screen 534, the suction force at the outer end will not When the lifting frame 533 stops, it will guide the lifting frame 533 to move upward; the contact signal sensor 536 is arranged on the inner wall of the water absorption channel 532 and above the lifting frame 533, and a plurality of contacts 537 are arranged at the bottom, which can monitor the position change of the lifting frame 533 in real time. When the lifting frame 533 rises to a certain position due to impurity accumulation and triggers the contact 537, it can timely feedback the signal, so as to know the working state of the water absorption channel 532, indicating that the clean water is currently in a state of complete back-absorption, and it is not appropriate to continue back-absorption, so as to take corresponding measures for sewage discharge; when this example is working, the clean water generated after sedimentation enters from the water absorption channel 532 of the cylinder 531, and the lifting frame 533 is flexibly adjusted according to the water flow under the action of the spring 535, and the filter 534 filters the inhaled water. If there are too many impurities, the lifting frame 533 rises and touches the contact 537 of the contact signal sensor 536, and the sensor sends a signal to ensure that the clean water is effectively absorbed and the quality meets the standard. At the same time, it can also automatically provide the drainage time of sewage, improve the efficiency of automatic processing, and reduce the dependence on manual labor.

[0044] In some examples, multiple contact signal sensors 536 are connected to a controller, and the purpose of the controller is to monitor all contact signal sensors 536. When a signal change occurs in one of the contact signal sensors 536, it may be caused by local impurity blockage, but the overall U-shaped pumping platform 51 is still in the clear water layer. If the controller detects signal changes in multiple contact signal sensors 536, it generates a corresponding water pump shutdown signal and starts the sewage discharge process at the same time.

[0045] like Figure 3As shown, in some examples, further, the aeration mechanism 60 includes: an aeration main pipe 61, a plurality of aeration branch pipes 62 and a plurality of aeration plates 63, the plurality of aeration branch pipes 62 are arranged in sequence and equidistantly at the bottom of the treatment tank 10; the aeration main pipe 61 is connected to each aeration branch pipe 62; the plurality of aeration plates 63 are fixedly arranged above each aeration branch pipe 62, and the plurality of aeration plates 63 on two adjacent aeration branch pipes 62 are in a staggered state.

[0046] In this example, the aeration main pipe 61 plays the role of collecting and transporting the gas required for aeration. The outer end of the aeration main pipe 61 is connected to an aeration pump to evenly distribute the gas to each aeration branch pipe 62; multiple aeration branch pipes 62 are equidistantly arranged at the bottom of the treatment tank 10 in sequence, and the gas received from the aeration main pipe 61 can be dispersed and transported to corresponding positions to ensure that the gas can cover a larger area at the bottom of the treatment tank 10; multiple aeration plates 63 are fixedly arranged above each aeration branch pipe 62, which can release the gas into the wastewater in a finely dispersed form, thereby increasing the contact area between the gas and the wastewater. The multiple aeration plates 63 are staggered to further improve the uniformity of gas distribution in the wastewater, so that all parts of the wastewater can be fully in contact with the gas. When working, the gas is first collected and allocated through the aeration main pipe 61, and then transported through the aeration branch pipes 62, and finally dispersed and released into the wastewater in the treatment tank 10 by the aeration plates 63, so that organic matter and other pollutants in the wastewater can be more easily oxidized and decomposed in an environment with sufficient oxygen, thereby improving the efficiency of printing and dyeing wastewater treatment, improving the water quality of the treated wastewater, ensuring the stable and efficient operation of the entire printing and dyeing wastewater treatment system, and reducing the occurrence of poor treatment effects due to uneven aeration.
