Description

Technical Field

[0001] This utility model relates to the field of river management technology, and in particular to a biomimetic composite biological bed for the treatment of black and odorous rivers. Background Technology

[0002] With the gradual development of urban modernization and industrialization, a large amount of domestic sewage and industrial wastewater are being discharged into rivers in excess of their capacity, gradually reducing the self-purification capacity of water bodies. Large amounts of organic pollutants are being discharged, and under the decomposition of aerobic microorganisms, the oxygen consumption rate of the water body exceeds the reoxygenation rate, causing oxygen deficiency. Organic matter is then anaerobically decomposed, producing substances that cause blackening and odor, ultimately leading to black and odorous water bodies. Therefore, the treatment of black and odorous water bodies requires a comprehensive approach involving physical, chemical, and ecological restoration measures to improve the reoxygenation capacity of the water body, reduce pollutant discharge, and enhance the self-purification capacity of the water body in order to restore the healthy balance of the aquatic ecosystem.

[0003] In existing technologies, such as the "A Treatment Device for Improving Black and Odorous Water Bodies in Rivers" with announcement number CN212450781U, a sedimentation chamber is included. An inlet is formed in the middle of one side of the sedimentation chamber, and an outlet is formed at the top of the other side. A flocculation and sedimentation outlet is formed at the bottom of the sedimentation chamber, and a collection bag is fitted at the flocculation and sedimentation outlet. Several flexible filter strips are fixed inside the sedimentation chamber. A flocculant input pipe is connected to the inlet of the sedimentation chamber, and the flocculant input pipe is connected to a flocculant silo. Although this technology is installed in the water body being treated, it does not occupy land space and can be used in the treatment process. While this technology allows for large-area towing and relocation, and the related bags are flexible structures that facilitate folding, transport, and unfolding, it has some drawbacks in practical use. In the water treatment process, a sedimentation chamber is used; however, due to the limited volume of the chamber, its treatment efficiency is low, and the area it can cover is limited, leading to unsatisfactory treatment results. Furthermore, this type of device can only float on the surface and cannot comprehensively purify the entire water body, making it difficult to fundamentally address pollution in the middle and bottom of the water. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a biomimetic composite biological bed for the treatment of black and odorous rivers, so as to solve the problems of existing devices having limited treatment range and being unable to purify the entire water body.

[0005] Based on the above objectives, this utility model provides a biomimetic composite biological bed for the treatment of black and odorous rivers, including a biomimetic component installed on one side of a riverbank. The biomimetic component is used to purify the river surface and improve the survival of plankton and animals. The biomimetic component includes a floating bed set on the water surface. Multiple buoys are fixedly connected to the top of the floating bed. Multiple first filling holes are opened inside the buoys. A water purification component is set at the bottom of the floating bed. The water purification component is used to purify the middle part of the river and reduce the ammonia nitrogen concentration in the river. An attachment component is set at the bottom of the water purification component. The attachment component is used to purify the bottom of the river and provide a large number of attachment sites. The biomimetic component, water purification component and attachment component work together to eliminate the black and odorous river and enable the river to form a healthy ecosystem.

[0006] Preferably, the width of the floating bed is adapted to the width of the river, the first filling hole is filled with coconut fiber, and the top of each of the multiple floating boxes is equipped with simulated plants.

[0007] Preferably, the two ends of the floating bed are respectively fixedly connected to connecting boxes, the top of the connecting boxes is fixedly connected to a pull rope, the top of the river embankment is fixedly connected to a positioning column, and a pulley is installed on one side of the top of the river embankment. The end of the pull rope away from the connecting box passes through the outside of the pulley and is fixedly connected to the top of the positioning column.

[0008] Preferably, the water purification component includes multiple traction ropes fixedly connected to the top of the floating bed, multiple branch ropes fixedly connected to the outside of the traction ropes, and multiple filling balls fixedly connected to the outside of the branch ropes. The filling balls are filled with zeolite, perlite and activated carbon, and the filling balls are shaped like net bags.

[0009] Preferably, the traction rope, branch rope, and filler ball are located in the middle of the river.

[0010] Preferably, the floating bed has two fixed anchors inside, the bottom of the anchors is fixedly connected to a hoisting rope, the bottom end of the hoisting rope is fixedly connected to a hoisting ring, the bottom of the two hoisting rings is fixedly connected to a caisson, the caisson is net-shaped, the inside of the caisson is filled with volcanic rock, and the height of the caisson is lower than the height of the lowest end of the traction rope.

[0011] Preferably, the attachment assembly includes a submerged bed installed on the bottom of the river, the width of which is adapted to the width of the river, and a plurality of second filling holes are provided on the top of the submerged bed, the interior of which is filled with coconut fiber.

[0012] Preferably, the top of the sinking bed is equipped with multiple underwater plants, and the top of the sinking bed has multiple bottom-sinking holes located on both sides of the second filling hole, with the bottom-sinking holes filled with rocks.

[0013] Preferably, the two ends of the submerged bed are fixedly connected to fixed plates, and the inside of the fixed plates is fixedly connected to fixed columns, the bottom of which is installed inside the riverbed.

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the coordinated action of the biomimetic components, water purification components, and attachment components, comprehensive treatment of the surface, middle, and bottom layers of water can be achieved, while expanding the treatment range and overcoming the limitation of traditional devices that can only float on the water surface. This ensures that the entire water body is effectively purified. At the same time, by combining various filling materials, biomimetic plants, and aquatic plants, a natural ecosystem is simulated, enabling the water body to have self-repair capabilities and building a stable water ecological balance.

[0016] Through the design of biomimetic components, the buoyancy of the floating bed is provided by the buoyancy box. By filling the floating bed with coconut fiber, microorganisms attach to the coconut fiber and grow, increasing the number of microorganisms in the black and odorous water. This is conducive to the large-scale and stable reproduction of microorganisms, greatly enhancing the natural purification capacity of the water body and amplifying its ability to digest pollution. At the same time, by planting simulated plants, the bed is made closer to nature, promoting ecological restoration and providing a habitat for plankton and aquatic animals, improving the self-purification capacity of the water body and contributing to the restoration of the river's ecology.

[0017] By setting up a water purification component, purifying materials such as zeolite, perlite, and activated carbon are suspended in the middle layer of the river using traction ropes, branch ropes, and filling balls. Zeolite adsorbs ammonia nitrogen, perlite enhances the adhesion of microorganisms, and activated carbon removes organic pollutants, thereby achieving a highly efficient water purification effect and increasing the activity of the middle layer of the water.

[0018] The submerged bed provides numerous microbial attachment sites for the riverbed through its attachment components, promoting microbial growth and accelerating the degradation of underwater pollutants. Simultaneously, coconut fiber is filled into the second filling hole to further enhance microbial attachment, thereby improving purification efficiency. Planting dwarf, cold-resistant Vallisneria natans on the seabed increases dissolved oxygen, improves the habitat for benthic organisms, and stabilizes seabed sediments, thus reducing the secondary release of pollutants from the riverbed. Furthermore, filling the bottom filling hole with rocks increases the stability of the riverbed and provides habitat for benthic organisms. The installation of fixing pillars and plates ensures that the submerged bed will not be washed away by water flow, allowing it to maintain its underwater purification function for a long time.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] Such as this utility model Figures 1 to 4 The invention described herein provides a biomimetic composite biological bed for the treatment of black and odorous rivers. It includes a biomimetic component installed on one side of a riverbank 3. The biomimetic component is used to purify the river surface and provide a habitat for plankton and animals. The biomimetic component includes an upper floating bed 1 set on the water surface. Multiple pontoons 4 are fixedly connected to the top of the upper floating bed 1. Multiple first filling holes 5 are opened inside the pontoons 4. A water purification component is set at the bottom of the upper floating bed 1. The water purification component is used to purify the middle part of the river and reduce the concentration of ammonia nitrogen in the river. An attachment component is set at the bottom of the water purification component. The attachment component is used to purify the bottom of the river and provide a large number of attachment sites. The biomimetic component, the water purification component and the attachment component work together to eliminate the black and odorous river and make the river form a good ecosystem.

[0029] By using biomimetic components, water purification components, and attachment components, the three work together to achieve comprehensive treatment of the surface, middle, and bottom layers of water bodies, while expanding the treatment range and overcoming the limitations of traditional devices that can only float on the water surface. This ensures that the entire water body is effectively purified. At the same time, by combining various filling materials, biomimetic plants, and aquatic plants, a natural ecosystem is simulated, enabling the water body to have self-repair capabilities and building a stable water ecological balance.

[0030] like Figures 1 to 3 As shown, the width of the upper floating bed 1 is adapted to the width of the river, the interior of the first filling hole 5 is filled with coconut fiber, and the tops of the multiple floating boxes 4 are all equipped with artificial plants 6.

[0031] Through the biomimetic components, the buoyancy box 4 on the floating bed 1 provides buoyancy. By filling the floating bed 1 with coconut fiber, microorganisms attach to the coconut fiber and grow, increasing the number of microorganisms in the black and odorous water body. This is conducive to the large-scale and stable reproduction of microorganisms, greatly enhancing the natural purification capacity of the water body and amplifying its ability to digest pollution. At the same time, by planting simulated plants 6, the bed body is made closer to nature, promoting ecological restoration and providing a habitat for plankton and aquatic animals, improving the self-purification capacity of the water body and facilitating the restoration of the river's ecology. Furthermore, by setting the width of the floating bed 1, the river can be treated to the maximum extent, thereby increasing the efficiency of the treatment.

[0032] like Figures 1 to 3 As shown, the two ends of the floating bed 1 are fixedly connected to the connecting box 20, the top of the connecting box 20 is fixedly connected to the pull rope 21, the top of the river embankment 3 is fixedly connected to the positioning column 23, and a pulley 22 is installed on one side of the top of the river embankment 3. The end of the pull rope 21 away from the connecting box 20 passes through the outside of the pulley 22 and is fixedly connected to the top of the positioning column 23.

[0033] The use of the pull rope 21 and positioning post 23 helps stabilize the floating bed 1 and prevents it from being washed away by the river. When installing the floating bed 1, first place the floating bed 1 on the water surface, and fix the positioning post 23 on the top of the riverbank 3. Then, pass one end of the pull rope 21 on the top of the connecting box 20 through the outside of the pulley 22 and fix it to the top of the positioning post 23. This makes the floating bed 1 float stably on the upper layer of the water and prevents it from being washed away by the river. At the same time, by setting the pull rope 21 to stainless steel, it is wear-resistant and rust-proof, which allows it to be used for a long time.

[0034] like Figures 1 to 3 As shown, the water purification component includes multiple traction ropes 7 fixedly connected to the top of the floating bed 1. Multiple branch ropes 8 are fixedly connected to the outside of the traction ropes 7. Multiple filling balls 9 are fixedly connected to the outside of the branch ropes 8. The filling balls 9 are filled with zeolite, perlite and activated carbon. The filling balls 9 are net-shaped. The traction ropes 7, branch ropes 8 and filling balls 9 are located in the middle of the river.

[0035] By using a specially designed water purification system, zeolite, perlite, and activated carbon are suspended in the middle layer of the river using traction ropes 7, branch ropes 8, and filler balls 9. Zeolite adsorbs ammonia nitrogen, perlite enhances microbial adhesion, and activated carbon removes organic pollutants, thus achieving a highly efficient water purification effect and increasing the activity of the middle layer of the water. The net-like filler balls 9 ensure smooth water flow and prevent clogging, while providing sufficient surface area for microbial growth. During installation, multiple filler balls 9 are connected to the outside of branch ropes 8, and multiple branch ropes 8 are connected to the outside of traction ropes 7. Then, multiple traction ropes 7 are connected to the bottom of the floating bed 1, causing the traction ropes 7, branch ropes 8, and filler balls 9 to be installed in the middle layer of the water, thereby purifying the middle layer. The traction ropes 7 and branch ropes 8 are made of nylon, allowing microorganisms to attach to their outer surface, further increasing the activity of the water.

[0036] like Figure 1 and Figure 2 As shown, the floating bed 1 has two fixedly connected stakes 10 inside. The bottom of the stakes 10 is fixedly connected to a hoisting rope 11. The bottom end of the hoisting rope 11 is fixedly connected to a hoisting ring 12. The bottom of the two hoisting rings 12 is fixedly connected to a caisson 13. The caisson 13 is net-shaped. The inside of the caisson 13 is filled with volcanic rock 14. The height of the caisson 13 is lower than the height of the lowest end of the traction rope 7.

[0037] By setting up stakes 10, suspension ropes 11, and a caisson 13, the suspension ropes 11 are fixed by stakes 10 and connected to the caisson 13, so that the floating bed 1 remains stable in the water and avoids violent shaking or displacement due to water flow or wind, thus improving the overall anti-interference ability. At the same time, the caisson 13 is set below the lowest end of the traction rope 7, ensuring that the filling ball 9 mainly acts on the middle of the water, while the caisson 13 acts on the bottom, forming a layered purification structure and improving the overall treatment effect. Meanwhile, by filling the caisson 13 with volcanic rock 14, the porous structure of the volcanic rock 14 provides a large number of attachment sites, which helps microorganisms attach and grow, promotes the degradation of organic pollutants, and enhances the self-purification ability of the water. At the same time, by setting the suspension rope 11 to be a nylon rope, microorganisms can attach to the outside of the nylon rope, thereby increasing the activity of the water.

[0038] like Figure 1 and Figure 4 As shown, the attachment assembly includes a submerged bed 2 installed at the bottom of the river. The width of the submerged bed 2 is adapted to the width of the river. The top of the submerged bed 2 has multiple second filling holes 16, which are filled with coconut fiber. Multiple underwater plants 19 are installed on the top of the submerged bed 2. The top of the submerged bed 2 has multiple bottom sinking holes 15, which are located on both sides of the second filling holes 16. The bottom sinking holes 15 are filled with rocks.

[0039] Through the attachment components, the submerged bed 2 provides a large number of microbial attachment sites for the riverbed, promoting microbial growth and accelerating the degradation of underwater pollutants. At the same time, coconut fiber is filled in the second filling hole 16 to further enhance microbial attachment and improve purification efficiency. Meanwhile, planting dwarf, cold-resistant Vallisneria natans on the bottom can increase dissolved oxygen in the water, improve the living environment of benthic organisms, stabilize underwater sediments, and reduce the secondary release of pollutants from the riverbed. At the same time, rocks are filled in the bottom filling hole 15 to increase the stability of the riverbed and provide habitat for benthic organisms.

[0040] like Figure 1 and Figure 4 As shown, fixed plates 17 are fixedly connected to both ends of the submerged bed 2, and fixed columns 18 are fixedly connected inside the fixed plates 17. The bottom of the fixed columns 18 is installed inside the bottom of the river.

[0041] The fixed columns 18 and fixed plates 17 ensure that the submerged bed 2 will not be washed away by the water flow, so that it can play a long-term role in water purification.
