Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a floating purification device used for a river sewage outlet. Background Art

[0002] Among current river outfall purification technologies, the use of solid microbial carriers is a common and relatively effective method. Microorganisms attached to the solid carriers purify water, utilizing their metabolic activity to degrade organic pollutants into harmless inorganic substances. However, existing solid microbial carrier technology faces numerous limitations and bottlenecks when treating actual river outfall wastewater, particularly when wastewater has poor fluidity, making efficient purification difficult.

[0003] Current technology usually places solid microbial carriers near sewage outlets, relying on natural water flow to bring sewage into contact with the microorganisms on the carriers for purification. 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 stagnant 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] Existing technologies also lack effective control over water flow direction and velocity, failing to effectively address the problem of fluctuating sewage flows at river outfalls, resulting in poor operational stability of purification equipment. For microorganisms, the dissolved oxygen concentration and organic pollutant concentrations in sewage directly influence their metabolic efficiency. However, traditional purification systems are unable to dynamically adjust these parameters, lacking optimal control over the microbial environment and unable to cope with the complex demands of water quality, resulting in suboptimal sewage treatment results.

[0005] Furthermore, existing floating purification equipment has structural design deficiencies. Traditional devices are mostly fixed, making them difficult to adapt to fluctuating river water levels. This can affect purification effectiveness due to inappropriate positioning, especially during flood and dry seasons. Furthermore, traditional purification methods are expensive to maintain and operate. In particular, when dirt accumulates on the surface of solid carriers, it can easily clog the purification device and degrade its function, requiring frequent manual cleaning and maintenance, increasing operating costs and management complexity.

[0006] In summary, existing solid microbial carrier purification technologies for river outfalls face a series of challenges, including insufficient contact between wastewater and microorganisms, insufficient wastewater flow control, difficulty regulating dissolved oxygen, poor equipment adaptability, and high maintenance costs. Therefore, there is an urgent need for a new type of floating purification device for river outfalls that can maintain high purification efficiency in environments with low flow rates and fluctuating water levels, and that features adaptive water level regulation and dynamic wastewater treatment capabilities, thereby addressing the shortcomings of existing technologies.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Adaptive Water Level Adjustment: This utility model utilizes a floating support structure to adjust the height of the purification device as the river water level changes, ensuring it always maintains optimal operating conditions. The combination of the float and mounting frame enables automatic adaptation to water level changes, ensuring the continuity and stability of the purification process, especially during extreme conditions such as flood and dry seasons.

[0022] 2. Optimizing the contact efficiency between sewage and microorganisms: The arrangement of the water separation plate and the solid microbial carrier layer within the purification tank ensures that sewage is more evenly distributed as it passes through the solid microbial carrier. The two separation plates effectively guide the water flow path, preventing sewage short-circuiting, ensuring that sewage fully contacts the microbial carrier, and increasing the degradation time and efficiency of organic pollutants.

[0023] 3. Braided Curtain Biofilm Carrier Efficiency Design: The braided curtain biofilm carrier structure further increases the contact area between the water and the biofilm. The braided curtain structure is suspended within the purification tank, forming a multi-layered water flow channel. This ensures that the water is evenly distributed during flow, fully contacting the biofilm and improving the degradation of organic pollutants.

[0024] 4. Dynamic Wastewater Circulation and Self-Cleaning Capabilities: The circulating water flow created by the two partitions within the purification tank ensures that wastewater repeatedly passes through the solid microbial carrier layer and the braided curtain-style biofilm carrier, extending the contact time between pollutants and microorganisms, thereby improving pollutant removal efficiency. Furthermore, the self-cleaning design effectively prevents the accumulation of dirt on the surface of the solid microbial carrier, reducing the frequency of manual cleaning and lowering maintenance costs.

[0025] 5. Multi-stage Filtration and Pollutant Interception: After wastewater is degraded by microorganisms, it is physically filtered through a filter plate. This multi-layered, pore-size design intercepts suspended particles and fine impurities in the water. This multi-stage filtration system not only removes residual pollutants but also improves water clarity, ensuring that wastewater meets emission standards.

[0026] 6. Automatic Impurity Recovery System: This utility model's impurity recovery mechanism utilizes a drive shaft and belt design. When impurities accumulate within the filter frame to a certain level, the recovery motor drives the belt, automatically transferring the impurities to a recovery bin for centralized processing. This design reduces manual operation, improves the system's automation level and eases maintenance, ensuring long-term, stable operation of the equipment.

[0027] 7. Intelligent Dissolved Oxygen Regulation: This utility model uses air aeration to oxygenate the water, increasing the dissolved oxygen concentration in the water and promoting the metabolic activity of microorganisms, thereby increasing the degradation rate of organic pollutants. Dynamic regulation of dissolved oxygen allows microorganisms to operate in an optimal environment, making it particularly suitable for treating wastewater with high organic matter concentrations, enhancing the overall treatment effect.

[0028] 8. Floating water inlet and telescopic bellows design: The combination of a telescopic bellows and an electric pump ensures that sewage can be continuously and stably pumped into the purification system under varying water levels. The telescopic bellows design allows for free adjustment as the water level fluctuates, preventing the impact of water level fluctuations on the water inlet process and ensuring water inlet stability throughout the system.

[0029] 9. Modular components facilitate expansion and maintenance: This utility model adopts a modular design, and each component, such as the purification tank, water inlet hopper, and filter frame, can be independently disassembled and replaced. This modular design facilitates equipment expansion and maintenance, reduces downtime, improves equipment maintainability and service life, and makes the entire system more flexible and adaptable.

[0030] 10. Environmentally friendly and low-cost operation: Through its floating support and automatic adjustment system, this utility model reduces reliance on external power. Its automatic impurity recovery and self-cleaning design significantly reduce the frequency of manual maintenance. These innovative designs not only reduce equipment operating and maintenance costs, but also improve the economic and environmental performance of wastewater purification, meeting current water environment governance requirements for energy conservation and emission reduction.

[0042] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0043] Example 1: Please refer to Figure 1-10 The utility model 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 a 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 a sewage purification structure is 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 a same impurity recovery structure is installed on the two fixed plates 7 on the same side;

[0044] The sewage purification structure includes a purification box 41, which is fixedly mounted on the bottom side of the two U-shaped frames 4. Two partition plates 42 are fixedly mounted on the inner wall of the purification box 41. Two partition water-passing plates 43 are fixedly mounted on the side close to each other of the two partition plates 42. A solid microbial 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. Two filter water-passing plates 46 are fixedly mounted on the purification box 41. Both sides of the mounting frame 1 are fixedly mounted with L-shaped connecting frames 47. 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. One end of the two telescopic bellows 49 is fixedly installed with a connecting pipe 410, and the two connecting pipes 410 are respectively connected to the two telescopic bellows 49. One end of the two connecting pipes 410 is fixedly installed with an electric pump 411. 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 pass through 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. 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. 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, while the filter water 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 can be 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 pumps 411 can be used to connect the connecting pipe 410 and the telescopic corrugated The pipe 49 and the water inlet hopper 48 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 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 will pass through the space above the two partition plates 42 and come into contact with the braided curtain biofilm carrier 45, so that the pollutants in the sewage are fully in contact with the biofilm grown on the filter water plate 46, thereby realizing biodegradation and completing the filtration and purification of the sewage.

[0045] 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 adjusting the height of the purification box 41 in the river channel so as to adjust it according to the depth of the river channel.

[0046] Furthermore, a threaded hole 52 is formed on the inner wall of the mounting bracket 1 , and the lifting adjustment screw rod 51 is threadedly mounted in the threaded hole 52 . The rotating lifting adjustment screw rod 51 can move in the threaded hole 52 by engaging with the thread of the threaded hole 52 .

[0047] 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 preventing the U-shaped frames 4 from being offset.

[0048] Furthermore, the solid microorganism carrier layer 44 is composed of a plurality of solid microorganism carriers.

[0049] The working principle is as follows: 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 filter water 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. The electric pump 411 can then transport the pumped water through the delivery pipe 412 to 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 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. Then the water flows through the space above the two partition plates 42 and contacts with the braided curtain biofilm carrier 45, so that the pollutants in the sewage are fully in contact 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 be matched with the thread of the threaded hole 52 The U-shaped frame 4 can be moved in the threaded hole 52, so that the lifting adjustment 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 offset. The continuously moving U-shaped frame 4 can drive the purification box 41 to move up and down, thereby adjusting the height of the purification box 41 in the river channel so as to adjust it according to the depth of the river channel. The telescopic bellows 49 can be telescopically adapted according to the adjustment of the height of the purification box 41. When the impurities in the filter frame 61 accumulate too much, 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 cooperation between the belts 73 enables the two transmission rollers 72 to rotate at the same time and enables the transmission belt 73 to perform a circular motion. The circular motion of the transmission belt 73 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 separate 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, thereby dumping 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 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 separate from the card slot 78.In order to centrally clean the impurities in the recovery box 77.

[0050] The floating purification method for a river sewage outlet using the device of this embodiment comprises the following steps:

[0051] S1. Device Placement: The floating purification device is placed at the river outlet, allowing the mounting frame to float on the water surface. The floating height of the float stabilizer is adjusted to ensure the device remains stable despite changes in water flow. 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.

[0052] S2. Water Inlet Operation: Start the electric pump 411, which draws sewage from the outlet into the inlet hopper 48 via the telescopic bellows 49 and connecting pipe 410, allowing it to smoothly enter the purification system. During this process, the telescopic bellows can be freely adjusted according to water level fluctuations, ensuring continuous and even sewage entry into the system. The inlet hopper 48 is located above the purification tank. Through a rational flow guidance design, sewage enters the tank smoothly, minimizing turbulence.

[0053] S3. Solid Microbial Carrier Layer Treatment: Sewage is pumped into the purification tank 41 through a delivery pipe 412, where it passes sequentially through a water divider plate 43 and a solid microbial carrier layer 44. A large number of functional microorganisms are attached to the solid microbial carrier layer 44, which metabolize organic pollutants in the water, achieving initial purification. The water divider plate 43 evenly distributes the water flow, ensuring sufficient contact between the sewage and the solid microbial carrier layer, ensuring uniformity and efficiency throughout the purification process.

[0054] S4. Braided Curtain Biofilm Carrier Treatment: After being treated by the solid microbial carrier layer, the water enters the braided curtain biofilm carrier 45. The braided curtain structure provides an ideal environment for microorganisms to attach, increasing their contact area with the water. The microbial communities growing on the biofilm further decompose organic pollutants in the water, further reducing pollutant concentrations. The unique design of the braided curtain structure ensures that water is fully distributed between the braids as it passes through, forming a continuous biodegradation zone.

[0055] S5. Filtration: After being treated by the biofilm carrier, the water continues to flow through the filter plate 46 for physical filtration. The filter plate uses multiple layers of different pore sizes to intercept fine particles and suspended solids in the water. This multi-stage filtration not only effectively removes particles from the water but also improves water clarity, providing a guarantee for subsequent drainage and ensuring that the final discharged water meets water quality requirements.

[0056] S6. Wastewater Circulation: Two partitions 42 create a circulating water flow within the purification tank, ensuring that the water repeatedly passes through the solid microbial carrier layer 44 and the braided biofilm carrier 45. This circulation ensures that most pollutants in the water are fully exposed to the microorganisms, resulting in efficient degradation. The partitions limit the water flow path to a specific range, preventing short-circuiting and improving purification efficiency and stability.

[0057] S7. Height Adjustment: Use handle 5 and lift adjustment screw 51 to adjust the height of the purification tank 41. Adjust the depth of the purification tank according to the fluctuating water level in the river to ensure that water can fully enter the purification device under different water level conditions. This height adjustment function allows the equipment to maintain efficient operation even under large fluctuations in water level, enhancing the adaptability and flexibility of the purification system.

[0058] S8, Impurity Recovery: During the water pumping and purification process, impurities floating on the water surface are intercepted by filter frame 61. When the impurities in the filter frame accumulate to a certain level, the recovery motor 75 is activated, which drives the transmission belt 73 to automatically transfer the impurities to the recovery tank 77 for centralized processing. This step ensures that floating objects on the water surface do not hinder the operation of the purification device, and can regularly collect and clean impurities, ensuring the long-term stable operation of the system.

[0059] S9. Purified Drainage: After multiple stages of purification, the water is discharged into the river through outlet 413. A flow control device is installed at the outlet to regulate the drainage rate to prevent adverse effects on the downstream river. After comprehensive treatment through the solid microbial carrier layer, braided curtain biofilm carrier, and filtration water flow plate, the discharged water is significantly improved in quality, meeting the established discharge standards and ensuring environmental friendliness.

[0060] 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 filter frame 61, which is fixedly mounted on the bottom side of the positioning frame 6, and the filter frame 61 is located in the water inlet bucket 48. The positioning frame 6 is movably mounted 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 mounted on the two fixed plates 7. A transmission roller 72 is fixedly sleeved on the two transmission rollers 72. The same transmission belt 73 is installed on the two transmission rollers 72. A linkage frame 74 is fixedly mounted on one side of the transmission belt 73. The linkage frame 74 is fixedly mounted on the top side of the positioning frame 6. A recovery motor 75 is fixedly mounted on one side of the fixed plate 7. The output end of the recovery motor 75 is fixedly mounted on one side of the corresponding transmission shaft 71. 1 is fixedly mounted with a positioning frame 76 on the top side, and a recovery box 77 is movably mounted 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 mounted in the card slot 78. The card block 79 is fixedly mounted on one side of the recovery box 77. The inner wall of the fixed plate 7 is provided with two rotating shaft holes 710, and the two transmission shafts 71 are rotatably mounted in the two rotating 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 the 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 reverse the output end, so that the filter frame 61 can be lowered back into the water inlet bucket 48 for continuous filtering use. The remaining features are the same as those in Example 1.
