Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a floating purification device and method for a river sewage outlet. Background Art

[0002] Among the current river sewage outlet purification technologies, the use of solid microbial carriers is a common and relatively effective means of purifying water by attaching microorganisms to solid carriers and using the metabolism of microorganisms to degrade organic pollutants into harmless inorganic substances. However, the existing solid microbial carrier technology has many limitations and bottlenecks when treating sewage from actual river sewage outlets, especially when the sewage has poor fluidity, making it difficult to achieve efficient purification.

[0003] Current technology usually places solid microbial carriers near sewage outlets, relying on natural water flow to purify sewage by contacting the microorganisms on the carriers. However, the sewage outlet environment in rivers is complex and uncontrollable, especially when the flow rate is low or the water body is in a static state, the contact effect between sewage and microbial carriers is greatly reduced, resulting in low purification efficiency. Due to the poor natural fluidity of the water body, the residence time of sewage on the surface of the microbial carrier is insufficient, and it cannot ensure that the pollutants fully react with the microorganisms, which limits the overall treatment effect. In addition, over time, the surface of the solid carrier is easily covered with dirt, which reduces the activity of the microorganisms and the permeability of the carrier, which further restricts the purification efficiency.

[0004] The existing technology also lacks effective control over the direction and velocity of water flow, and fails to effectively solve the problem of sewage flow fluctuations at river discharge outlets, resulting in poor operating stability of the purification device. For microorganisms, the concentration of dissolved oxygen and organic pollutants in sewage directly affects their metabolic efficiency, but traditional purification systems cannot dynamically adjust these parameters, lack optimized control over the microbial environment, and cannot cope with the changing needs of complex water quality, resulting in unsatisfactory sewage treatment results.

[0005] In addition, the structural design of existing floating purification equipment is also insufficient. Traditional devices are mostly fixed and difficult to adapt to changes in river water levels, especially during flood or dry seasons, when the purification effect is affected by inappropriate device locations. At the same time, the maintenance and operating costs of traditional purification methods are high, especially when dirt accumulates on the surface of solid carriers, which can easily lead to clogging and functional degradation of the purification device, requiring frequent manual cleaning and maintenance, increasing operating costs and management difficulties.

[0006] In summary, the existing solid microbial carrier purification technology for river sewage outlets faces a series of problems such as insufficient contact between sewage and microorganisms, insufficient sewage flow control, difficulty in dissolved oxygen regulation, poor equipment adaptability and high maintenance costs. Therefore, there is an urgent need for a new floating purification device and method for river sewage outlets, which can maintain efficient purification effects in an environment with low flow rate and water level changes, and has adaptive water level regulation function and dynamic sewage treatment capacity, so as to solve the shortcomings of the existing technology.

[0019] Preferably, the solid microorganism carrier layer is composed of a plurality of solid microorganism carriers.

[0020] The present invention also includes a floating purification method for a river sewage outlet, the method comprising the following steps:

[0021] S1. Device placement: Place the floating purification device at the river discharge outlet, so that the mounting frame floats on the water surface, and adjusts the distance between the float and the water surface by the floating height of the float stabilizing device to ensure that the device remains stable when the water flow changes. The design of the floating support structure enables the purification device to adapt to changes in the river water level, thereby ensuring the continuity and effectiveness of the purification process.

[0022] S2. Water inlet operation: Start the electric pump, and pump the sewage from the sewage outlet into the water inlet bucket through the telescopic bellows and the connecting pipe, so that the sewage can smoothly enter the purification system. In this process, the telescopic bellows can be freely adjusted according to the change of water level to ensure that the sewage can be continuously and evenly pumped into the system. The water inlet bucket is set above the purification box, and through the reasonable water flow guiding design, the sewage can smoothly enter the purification box and reduce the generation of turbulence.

[0023] S3, solid microbial carrier layer treatment: the pumped sewage is introduced into the purification box through the delivery pipe, and the water passes through the separation water plate and the solid microbial carrier layer in turn. A large number of functional microorganisms are attached to the solid microbial carrier layer, which decompose the organic pollutants in the water through metabolism to achieve preliminary purification. The separation water plate is used to evenly distribute the water flow so that the sewage can fully contact with the solid microbial carrier layer, ensuring the uniformity and efficiency of the entire purification process.

[0024] S4. Braided curtain biofilm carrier treatment: The water body treated by the solid microbial carrier layer enters the braided curtain biofilm carrier. The braided curtain biofilm carrier provides a good attachment environment for microorganisms through its braided curtain structure, increasing the contact area with the water body. The microbial community growing on the biofilm can further decompose organic pollutants in the water, further reducing the concentration of pollutants in the water body. The special design of the braided curtain structure allows the water body to be fully distributed between the braided curtains when the water flows through, forming a continuous biodegradation area.

[0025] S5, filtration process: The water treated by the biofilm carrier continues to flow through the filter water plate (46) for physical filtration. The filter water plate adopts a multi-layer design with different apertures to intercept fine particles and suspended matter in the water. Through multi-stage filtration, not only the particles in the water are effectively removed, but also the transparency of the water is improved, which provides a guarantee for subsequent drainage and ensures that the final discharged water meets the water quality requirements.

[0026] S6. Wastewater circulation: Two partitions are used to form a circulating water flow in the purification box, ensuring that the water can repeatedly pass through the solid microbial carrier layer and the braided curtain biofilm carrier. This circulating flow method ensures that most pollutants in the water can fully contact with the microorganisms and thus be efficiently degraded. The function of the partition is to limit the flow path of the water to a specific range, avoid water short-circuiting, and improve purification efficiency and stability.

[0027] S7. Height adjustment: Use the handle and lifting screw to adjust the height of the purification box, and adjust the sinking depth of the purification box according to the water level changes in the river to ensure that the water can fully enter the purification device under different water level conditions. The height adjustment function enables the equipment to maintain efficient operation even when the water level rises and falls greatly, enhancing the adaptability and flexibility of the purification system.

[0028] S8, impurity recovery: During the water pumping and purification process, the floating impurities on the water surface are intercepted by the filter frame. When the impurities in the filter frame accumulate to a certain level, the recovery motor is started, and the recovery motor drives the transmission belt to automatically transfer the impurities to the recovery box for centralized treatment. This step ensures that floating objects on the water surface will not hinder the operation of the purification device, and can regularly collect and clean impurities to ensure the long-term stable operation of the system.

[0029] S9. Drainage after purification: After multiple levels of purification, the water is discharged into the river through the outlet. A flow control device is installed at the outlet to adjust the drainage speed to prevent adverse effects on the downstream river. After the discharged water is treated by the solid microbial carrier layer, braided curtain biofilm carrier and filter water board, the water quality is significantly improved and meets the set discharge standards, ensuring environmental friendliness.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Adaptive water level adjustment: The present invention uses the design of a floating support structure to enable the purification device to adjust its height as the water level of the river changes, ensuring that the purification device always remains in the best working state. The cooperation between the float and the mounting frame realizes automatic adaptation to water level changes, especially in extreme conditions such as flood season or dry season, ensuring the continuity and stability of the purification process.

[0032] 2. Optimize the contact efficiency between sewage and microorganisms: Through the arrangement of the water separation plate and the solid microbial carrier layer in the purification box, the sewage can be more evenly distributed when passing through the solid microbial carrier. The setting of the two separation plates effectively guides the water flow path, avoids the short circuit of sewage, enables the sewage to fully contact with the microbial carrier, and increases the degradation time and efficiency of organic pollutants.

[0033] 3. Braided curtain biofilm carrier efficiency enhancement design: The braided curtain biofilm carrier structure is set up to further increase the contact area between the water body and the biofilm. The braided curtain structure is arranged in the purification box by hanging to form a multi-level water flow channel to ensure that the water body can be evenly distributed during the flow process, fully contact the biofilm, and improve the degradation effect of organic pollutants.

[0034] 4. Dynamic sewage circulation and self-cleaning ability: The circulating water flow formed by the two partitions in the purification box ensures that the sewage repeatedly passes through the solid microbial carrier layer and the braided curtain biofilm carrier, prolonging the contact time between pollutants and microorganisms, thereby improving the removal efficiency of pollutants. At the same time, the self-cleaning design effectively prevents dirt from accumulating on the surface of the solid microbial carrier, reducing the frequency of manual cleaning and reducing maintenance costs.

[0035] 5. Multi-stage filtration and pollutant interception: After the sewage is degraded by microorganisms, a filter water plate is set up for physical filtration, and the suspended particles and fine impurities in the water are intercepted through the design of multiple layers with different apertures. This multi-stage filtration system not only removes residual pollutants, but also improves the transparency of the water body, ensuring that the drainage meets the discharge standards.

[0036] 6. Automatic impurity recovery system: The impurity recovery structure of the present invention adopts a design combining a transmission shaft and a transmission belt. When the impurities in the filter frame accumulate to a certain extent, the recovery motor drives the transmission belt to automatically transfer the impurities to the recovery box for centralized treatment. This design reduces manual operation, improves the automation level and maintenance convenience of the system, and ensures long-term stable operation of the equipment.

[0037] 7. Intelligent dissolved oxygen regulation: In the present invention, the water body is oxygenated by an air aeration device, which increases the concentration of dissolved oxygen in the water, promotes the metabolic activity of microorganisms, and thus increases the degradation rate of organic pollutants. The dynamic regulation of dissolved oxygen enables microorganisms to work in the best environment, which is particularly suitable for treating sewage with high organic matter concentration, and enhances the overall treatment effect.

[0038] 8. Floating water inlet and telescopic bellows design: The combination of telescopic bellows and electric pump ensures that sewage can be continuously and stably pumped into the purification system under different water level conditions. The design of the telescopic bellows enables it to be freely adjusted as the water level changes, avoiding the impact of water level fluctuations on the water inlet process and ensuring the water inlet stability of the entire system.

[0039] 9. Modular components facilitate expansion and maintenance: The present invention adopts a modular design, and each component such as the purification box, water inlet bucket, filter frame, etc. can be independently disassembled and replaced. This modular design facilitates the expansion and maintenance of the equipment, reduces downtime, improves the maintainability and service life of the equipment, and makes the entire system more flexible and adaptable.

[0040] 10. Environmentally friendly and low-cost operation mode: Through floating support and automatic adjustment system, the present invention reduces the dependence on external power, and the automatic impurity recovery and self-cleaning design significantly reduce the frequency of manual maintenance. These innovative designs not only reduce the operation and maintenance costs of the equipment, but also improve the economy and environmental protection of sewage purification, which meets the current requirements of water environment management for energy conservation and emission reduction.

DETAILED DESCRIPTION

[0052] 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.

[0053] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a floating purification device for a river sewage outlet, comprising a mounting frame 1; two connecting frames 2 are fixedly installed on both sides of the mounting frame 1, and the same floating body 3 is fixedly installed on the two connecting frames 2 on the same side, two U-shaped frames 4 are slidably installed on the mounting frame 1, and sewage purification structures are installed on the two U-shaped frames 4, and an adjustment structure is installed on the U-shaped frames 4. A positioning frame 6 is installed on the sewage purification structure, and a filtering structure is installed on the positioning frame 6. Fixed plates 7 are fixedly installed on both sides of the mounting frame 1, and the same impurity recovery structure is installed on the two fixed plates 7 on the same side;

[0054] The sewage purification structure includes a purification box 41, which is fixedly installed on the bottom side of the two U-shaped frames 4, and two partition plates 42 are fixedly installed on the inner wall of the purification box 41. Two partition water-passing plates 43 are fixedly installed on the side where the two partition plates 42 are close to each other, and a solid microorganism carrier layer 44 is provided between the two partition water-passing plates 43. A plurality of braided curtain-type biofilm carriers 45 are connected to the inner wall of the purification box 41, and two filter water-passing plates 46 are fixedly installed on the purification box 41. The two filter water-passing plates 46 are connected to the purification box 41. L-shaped connecting frames 47 are fixedly installed on both sides of the mounting frame 1. The two L A water inlet bucket 48 is fixedly installed on the connecting frame 47, and a telescopic bellows 49 is fixedly installed on the bottom side of the two water inlet buckets 48. The two telescopic bellows 49 are respectively connected to the two water inlet buckets 48. A connecting pipe 410 is fixedly installed on one end of the two telescopic bellows 49. The two connecting pipes 410 are respectively connected to the two telescopic bellows 49. An electric pump 411 is fixedly installed on one end of the two connecting pipes 410. One end of two delivery pipes 412 is fixedly installed on the two electric pumps 411. The other ends of the two delivery pipes 412 penetrate the purification box 41 and extend into the purification box 41. A plurality of water outlets 413 are fixedly installed on each delivery pipe 412, and the water outlet 413 is located between the two partition plates 42. When in use, the device is placed at the sewage outlet of the river, and the two floats 3 can be used to make the device float on the river surface, and can be raised and lowered according to the height of the river surface, the water inlet bucket 48 is slightly immersed in the river surface, and the filtering water-passing plate 46 is completely immersed in the water. In the case of a large water flow, it can be tied to the connecting frame 2 with a rope, and the other end of the rope is fixed to the shore to prevent the device from being washed away. When in use, the electric pumps 411 on both sides can be turned on, and the electric pumps 411 can be used to connect the connecting pipe 410 and the telescopic corrugated The pipe 49 and the water inlet hopper 48 are used to pump water, so that the water flows into the water inlet hopper 48 and is input between the two partition plates 42, which can accelerate the water flow to pass between the partition water-passing plate 43 and the solid microbial carrier layer 44. When the water flows through the solid microbial carrier layer 44, the microorganisms on the carrier can absorb organic pollutants and other harmful substances in the water body. After that, the water flows through the space above the two partition plates 42 and contacts with the braided curtain type biofilm carrier 45, so that the pollutants in the sewage are fully contacted with the biofilm grown on the filter water-passing plate 46, thereby realizing biodegradation and completing the filtration and purification of the sewage.

[0055] Furthermore, the adjustment structure includes two handles 5, one end of each handle 5 is fixedly installed with a lifting adjustment screw rod 51, the two lifting adjustment screw rods 51 are rotatably installed on the two U-shaped frames 4 respectively, one end of the two lifting adjustment screw rods 51 is rotatably installed on one side of the same purification box 41, and the two lifting adjustment screw rods 51 are both threadedly installed on the mounting frame 1. Rotating the handle 5 can drive the lifting adjustment screw rod 51 to rotate, and the rotating lifting adjustment screw rod 51 can drive the U-shaped frame 4 to move vertically. The continuously moving U-shaped frame 4 can drive the purification box 41 to rise and fall, thereby being able to adjust the height of the purification box 41 in the river channel so as to adjust it according to the depth of the river channel.

[0056] Furthermore, a threaded hole 52 is formed on the inner wall of the mounting frame 1 , and the lifting and adjusting screw rod 51 is threadedly installed in the threaded hole 52 . The rotating lifting and adjusting screw rod 51 can move in the threaded hole 52 by engaging with the thread of the threaded hole 52 .

[0057] Furthermore, four guide sliding holes 414 are symmetrically opened on the inner wall of the mounting frame 1, and the two ends of the two U-shaped frames 4 are respectively slidably installed in the four guide sliding holes 414. The U-shaped frames 4 can slide in the corresponding guide sliding holes 414 when lifting, thereby avoiding the U-shaped frames 4 from being offset.

[0058] Furthermore, the solid microorganism carrier layer 44 is composed of a plurality of solid microorganism carriers.

[0059] The working principle is as follows: when in use, the device is placed at the sewage outlet of the river, and two floats 3 are used to make the device float on the river surface, and it can be raised and lowered according to the height of the river surface. The water inlet bucket 48 is slightly immersed in the river surface, and the filtering water-passing plate 46 is completely immersed in the water. When the water flow is large, it can be tied to the connecting frame 2 with a rope, and the other end of the rope is fixed to the shore to prevent the device from being washed away. When in use, the electric pumps 411 on both sides can be turned on. The electric pump 411 can use the connecting pipe 410, the telescopic bellows 49 and the water inlet bucket 48 to pump water, so that water flows into the water inlet bucket 48. Impurities floating on the water surface will be blocked and filtered by the filter frame 61 when they are sucked into the water inlet bucket 48 with the water, and the electric pump 411 can pump the pumped water through the delivery pipe 412 and multiple water outlets. The port 413 is input between the two partition plates 42, which can accelerate the water flow to pass between the partition water-passing plate 43 and the solid microorganism carrier layer 44. When the water flows through the solid microorganism carrier layer 44, the microorganisms on the carrier can absorb organic pollutants and other harmful substances in the water body. Then the water flows through the space above the two partition plates 42 and contacts with the braided curtain type biofilm carrier 45, so that the pollutants in the sewage are fully contacted with the biofilm grown on the filter water-passing plate 46, thereby achieving biodegradation and completing the filtration and purification of the sewage. Finally, the sewage will flow out through the filter water-passing plates 46 on both sides. By turning the handle 5, the lifting and adjusting screw rod 51 can be driven to rotate, and the rotating lifting and adjusting screw rod 51 can cooperate with the thread of the threaded hole 52 The U-shaped frame 4 can move in the threaded hole 52, so that the lifting and adjusting screw rod 51 can rotate on the U-shaped frame 4 and drive the U-shaped frame 4 to move vertically. The vertically moving U-shaped frame 4 can slide in the two solid microorganism carrier layers 44 to avoid deviation. The continuously moving U-shaped frame 4 can drive the purification box 41 to rise and fall, so that the height of the purification box 41 in the river channel can be adjusted so as to adjust it according to the depth of the river channel. The telescopic bellows 49 can be telescopic and adapted according to the adjustment of the height of the purification box 41. When too much impurity accumulates in the filter frame 61, the corresponding recovery motor 75 can be turned on. The output end of the recovery motor 75 will drive one of the transmission shafts 71 to rotate, so that the transmission shaft 71 drives the transmission roller 72 to rotate, and the two transmission rollers 72 and the transmission The transmission between the belts 73 enables the two transmission rollers 72 to rotate at the same time and enables the transmission belt 73 to make a circular motion. The transmission belt 73 in the circular motion can drive the positioning frame 6 to rise through the linkage frame 74, so that the positioning frame 6 drives the filter frame 61 to disengage from the water inlet bucket 48. When the linkage frame 74 moves to the corner, the positioning frame 6 and the filter frame 61 will be flipped under the influence of the circular motion of the transmission belt 73, so that the impurities in the filter frame 61 are dumped into the recovery box 77. After the dumping is completed, the recovery motor 75 is driven to make its output end run in the reverse direction, so that the filter frame 61 can be lowered into the water inlet bucket 48 again for continuous filtering use. By pulling the recovery box 77 upwards, it can drive the card block 79 to disengage from the card slot 78.In order to centrally clean the impurities in the recovery box 77.

[0060] The floating purification method for a river sewage outlet using the device of this embodiment comprises the following steps:

[0061] S1. Device placement: Place the floating purification device at the river discharge outlet, so that the mounting frame floats on the water surface, and adjusts the distance between the float and the water surface by the floating height of the float stabilizing device to ensure that the device remains stable when the water flow changes. The design of the floating support structure enables the purification device to adapt to changes in the river water level, thereby ensuring the continuity and effectiveness of the purification process.

[0062] S2, water inlet operation: start the electric pump 411, and pump the sewage from the sewage outlet into the water inlet 48 through the telescopic bellows 49 and the connecting pipe 410, so that the sewage can smoothly enter the purification system. In this process, the telescopic bellows can be freely adjusted according to the change of water level to ensure that the sewage can be continuously and evenly pumped into the system. The water inlet 48 is set above the purification box, and through the reasonable water flow guiding design, the sewage can smoothly enter the purification box, reducing the generation of turbulence.

[0063] S3, solid microbial carrier layer treatment: The pumped sewage is introduced into the purification box 41 through the delivery pipe 412, and the water passes through the partition water plate 43 and the solid microbial carrier layer 44 in sequence. A large number of functional microorganisms are attached to the solid microbial carrier layer 44, which decompose the organic pollutants in the water through metabolism to achieve preliminary purification. The partition water plate 43 is used to evenly distribute the water flow so that the sewage can fully contact the solid microbial carrier layer, ensuring the uniformity and efficiency of the entire purification process.

[0064] S4, braided curtain biofilm carrier treatment: The water body treated by the solid microbial carrier layer enters the braided curtain biofilm carrier 45. The braided curtain biofilm carrier provides a good attachment environment for microorganisms through its braided curtain structure, increasing the contact area with the water body. The microbial community growing on the biofilm can further decompose organic pollutants in the water, further reducing the concentration of pollutants in the water body. The special design of the braided curtain structure allows the water body to be fully distributed between the braided curtains when the water flows through, forming a continuous biodegradation area.

[0065] S5, Filtration process: The water treated by the biofilm carrier continues to flow through the filter water plate 46 for physical filtration. The filter water plate adopts a multi-layer design with different apertures to intercept fine particles and suspended matter in the water. Through multi-stage filtration, not only the particles in the water are effectively removed, but also the transparency of the water is improved, which provides a guarantee for subsequent drainage and ensures that the final discharged water meets the water quality requirements.

[0066] S6. Sewage circulation: A circulating water flow is formed in the purification box through two partitions 42, ensuring that the water can repeatedly pass through the solid microbial carrier layer 44 and the braided curtain biofilm carrier 45. This circulating flow method ensures that most pollutants in the water can fully contact with the microorganisms and thus be efficiently degraded. The function of the partition is to limit the flow path of the water body to a specific range, avoid water short-circuiting, and improve purification efficiency and stability.

[0067] S7. Height adjustment: The height of the purification box 41 is adjusted by using the handle 5 and the lifting adjustment screw 51, and the sinking depth of the purification box is adjusted according to the water level change of the river channel to ensure that the water body can fully enter the purification device under different water level conditions. The height adjustment function enables the equipment to maintain efficient operation under large changes in water level, thereby enhancing the adaptability and flexibility of the purification system.

[0068] S8, impurity recovery: During the water pumping and purification process, floating impurities on the water surface are intercepted by the filter frame 61. When the impurities in the filter frame accumulate to a certain extent, the recovery motor 75 is started, and the recovery motor drives the transmission belt 73 to automatically transfer the impurities to the recovery box 77 for centralized treatment. This step ensures that floating objects on the water surface will not hinder the operation of the purification device, and can regularly collect and clean impurities to ensure the long-term stable operation of the system.

[0069] S9, drainage after purification: The water after multi-stage purification is discharged into the river through the outlet 413. A flow control device is provided at the outlet to adjust the drainage speed to prevent adverse effects on the downstream river. After the discharged water is comprehensively treated by the solid microbial carrier layer, the braided curtain biofilm carrier and the filter water plate, the water quality is significantly improved and meets the set discharge standards, ensuring environmental friendliness.

[0070] Example 2: Figure 1-8In order to avoid the suction of impurities during the pumping process, a filtering structure is arranged on the positioning frame 6, and an impurity recovery structure is arranged on the fixed plate 7. The filtering structure includes a filtering frame 61, which is fixedly installed on the bottom side of the positioning frame 6, and the filtering frame 61 is located in the water inlet bucket 48. The positioning frame 6 is movably installed on the water inlet bucket 48. The impurity recovery structure includes two transmission shafts 71, and the two ends of the two transmission shafts 71 are rotatably installed on the two fixed plates 7 respectively. The two transmission shafts 71 are fixedly sleeved with transmission rollers 72, and the same transmission belt 73 is installed on the two transmission rollers 72 for transmission. A linkage frame 74 is fixedly installed on one side of the transmission belt 73, and the linkage frame 74 is fixedly installed on the top side of the positioning frame 6. A recovery motor 75 is fixedly installed on one side of the fixed plate 7, and the output end of the recovery motor 75 is fixedly installed on one side of a corresponding transmission shaft 71. The mounting frame 1 is fixedly installed with a positioning frame 76, and a recovery box 77 is movably installed on the positioning frame 76. A card slot 78 is provided on the inner wall of the positioning frame 76, and a card block 79 is movably installed in the card slot 78. The card block 79 is fixedly installed on one side of the recovery box 77. Two shaft holes 710 are provided on the inner wall of the fixing plate 7, and two transmission shafts 71 are rotatably installed in the two shaft holes 710 respectively. Impurities floating on the water surface will be blocked and filtered by the filter frame 61 when they are sucked into the water inlet bucket 48 with water. When the impurities in the filter frame 61 accumulate too much, the corresponding recovery motor 75 can be turned on to dump the impurities in the filter frame 61 into the recovery box 77. After the dumping is completed, the recovery motor 75 is driven to make its output end run in reverse, so that the filter frame 61 can be lowered into the water inlet bucket 48 again for continuous filtering use. The remaining features are the same as those of Example 1.

10. Floating purification method for river sewage outlets, It is characterized in that The method comprises the following steps: S1. Device placement: Place the floating purification device at the river discharge outlet, so that the mounting frame floats on the water surface, and adjusts the distance between the float and the water surface by the floating height of the float stabilizing device to ensure that the device remains stable when the water flow changes. The design of the floating support structure enables the purification device to adapt to changes in the river water level, thereby ensuring the continuity and effectiveness of the purification process. S2, water inlet operation: start the electric pump (411), and pump the sewage from the sewage outlet into the water inlet bucket (48) through the telescopic bellows (49) and the connecting pipe (410), so that the sewage can smoothly enter the purification system. In this process, the telescopic bellows can be freely adjusted according to the change of water level to ensure that the sewage can be continuously and evenly pumped into the system. The water inlet bucket (48) is arranged above the purification box, and through a reasonable water flow guiding design, the sewage can smoothly enter the purification box, reducing the generation of turbulence. S3, solid microbial carrier layer treatment: The pumped sewage is introduced into the purification box (41) through the conveying pipe (412), and the water passes through the partition water-passing plate (43) and the solid microbial carrier layer (44) in sequence. A large number of functional microorganisms are attached to the solid microbial carrier layer (44), and these microorganisms decompose organic pollutants in the water through metabolism to achieve preliminary purification. The partition water-passing plate (43) is used to evenly distribute the water flow so that the sewage can fully contact with the solid microbial carrier layer, ensuring the uniformity and efficiency of the entire purification process. S4. Braided curtain biofilm carrier treatment: The water body treated by the solid microbial carrier layer enters the braided curtain biofilm carrier (45). The braided curtain biofilm carrier provides a good attachment environment for microorganisms through its braided curtain structure, increasing the contact area with the water body. The microbial community growing on the biofilm can further decompose organic pollutants in the water, further reducing the concentration of pollutants in the water body. The special design of the braided curtain structure allows the water body to be fully distributed between the braided curtains when the water flows through, forming a continuous biodegradation area. S5, filtration process: The water treated by the biofilm carrier continues to flow through the filter water plate (46) for physical filtration. The filter water plate adopts a multi-layer design with different apertures to intercept fine particles and suspended matter in the water. Through multi-stage filtration, not only the particles in the water are effectively removed, but also the transparency of the water is improved, which provides a guarantee for subsequent drainage and ensures that the final discharged water meets the water quality requirements. S6. Wastewater circulation: A circulating water flow is formed in the purification box through two partitions (42), ensuring that the water can repeatedly pass through the solid microbial carrier layer (44) and the braided curtain biofilm carrier (45). This circulating flow mode ensures that most pollutants in the water can fully contact with the microorganisms and thus be efficiently degraded. The function of the partition is to limit the flow path of the water to a specific range, avoid water short-circuiting, and improve purification efficiency and stability. S7. Height adjustment: The height of the purification box (41) is adjusted using the handle (5) and the lifting adjustment screw (51), and the sinking depth of the purification box is adjusted according to the water level change of the river channel to ensure that the water body can fully enter the purification device under different water level conditions. The height adjustment function enables the equipment to maintain efficient operation even when the water level rises and falls greatly, thereby enhancing the adaptability and flexibility of the purification system. S8, impurity recovery: During the water pumping and purification process, floating impurities on the water surface are intercepted by the filter frame (61). When the impurities in the filter frame accumulate to a certain extent, the recovery motor (75) is started, and the recovery motor drives the transmission belt (73) to automatically transfer the impurities to the recovery box (77) for centralized treatment. This step ensures that floating objects on the water surface will not hinder the operation of the purification device, and can regularly collect and clean impurities to ensure the long-term stable operation of the system. S9, drainage after purification: The water after multi-stage purification is discharged into the river through the outlet (413). A flow control device is provided at the outlet to adjust the drainage speed to prevent adverse effects on the downstream river. The discharged water passes through the solid microbial carrier layer, the braided curtain biofilm carrier and After comprehensive treatment of the filter water board, the water quality has been significantly improved and reached the set discharge standards. Ensure environmental friendliness.
