Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a bionic aquatic plant filler system. Background Art

[0002] In the field of river management in environmental engineering, river pollution and ecological damage have long been major issues that require urgent resolution. With the rapid advancement of urbanization and increasing industrial activity, large amounts of sewage, garbage, and waste are discharged into rivers, causing a sharp deterioration in river water quality and severe damage to aquatic ecosystems.

[0003] Traditional river management methods primarily include physical, chemical, and biological methods. While physical methods like dredging can remove silt and sediment from the riverbed, this approach is labor-intensive and requires significant manpower, material, and financial resources. Furthermore, the dredging process can further damage the river's ecosystem. Other methods, such as embankment construction, primarily focus on altering the river's shape and flow rate, but often have limited impact on water quality.

[0004] Chemical treatment typically involves injecting chemicals, such as flocculants and oxidants, into rivers to remove pollutants. However, this approach is not only costly, but the use of chemicals can also lead to new environmental pollution problems and even pose fatal risks to aquatic life. Furthermore, chemical treatment methods often only temporarily address the presence of pollutants and fail to fundamentally restore the ecological function of the river.

[0005] Biological methods are currently a popular treatment method, but they also have numerous drawbacks. The common biofilm method requires the construction of complex carrier structures, which not only increases construction costs but also presents numerous difficulties in subsequent operation and maintenance. For example, the carrier structure is prone to clogging, requiring regular cleaning and replacement, increasing maintenance workload and costs.

[0006] Planting aquatic plants can absorb nutrients and pollutants from water bodies to a certain extent, but common aquatic plants are significantly affected by seasonal changes. In winter or during periods of low temperatures, plant growth slows or even stops, significantly reducing their ability to absorb and purify pollutants. Furthermore, in conditions of fast currents or significant water level fluctuations, aquatic plants are easily washed away or damaged, compromising their effectiveness.

[0007] When it comes to the management of narrow river channels, due to limited space, large-scale sewage treatment equipment is difficult to install and operate, and traditional treatment methods are more restricted in their application. The water flow rate in narrow river channels is usually fast, and traditional fillers are easily entangled and piled together under the action of the water flow, which not only affects the normal flow of water, but also reduces the filler's treatment effect on pollutants. In addition, changes in river water levels, especially during the dry season, will cause some treatment facilities to be exposed to the air and unable to function properly, thus affecting the effectiveness and stability of the entire treatment project. The hard riverbed cannot use fixed piles at the bottom. Fixed purification equipment requires the construction of intercepting dams and pumping construction, which is very expensive.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly defined.

[0037] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 6 As shown, this example provides a bionic aquatic plant filler system. The bionic aquatic plant filler system 1 includes at least one group of bionic aquatic plant filler components 10. The bionic aquatic plant filler component 10 includes a chain 111, multiple biological rope fillers 112, multiple floats 113 and counterweights 114. The number of biological rope fillers 112 corresponds one to one to the number of floats 113; wherein the above-mentioned multiple biological rope fillers 112 are distributed in sequence along the length direction of the chain 111 and are connected to the chain 111, and the float 113 is arranged on the top of the biological rope filler 112; the counterweight 114 is connected to the end of the chain 111.

[0040] In this example, the counterweight 114 is made of concrete, stone or metal, or other forms of heavy objects. Through the action of gravity, the entire bionic aquatic grass filler assembly 10 can be stably fixed to the riverbed without relying on expansion bolts or fixed piles, which significantly reduces costs and simplifies the installation process.

[0041] In this example, the float 113 can be made of a material that is water-resistant, corrosion-resistant and has a certain degree of elasticity. For example, the float 113 can be made of a foam material; the float 113 and the top of the biological rope filler 112 can be stably fixed together by melting, which can ensure the stability of the connection while not affecting the buoyancy of the float 113; of course, they can also be connected together with a rope.

[0042] In this example, chain 111 may be a stainless steel chain, which may be composed of multiple strong links, each of which is tightly connected and flexible, allowing it to flex and extend naturally with changes in water flow and water level. The length and weight of the chain are selected based on actual needs to ensure that the filler maintains a stable posture under various water flow conditions.

[0043] In this example, the bio-rope filler 112 includes a central rope 1121 and filler fiber filaments 1122 wound around the central rope 1121 and having a microporous surface structure. The lower end of the central rope 1121 is detachably connected to the chain 111, and the upper end of the central rope 1121 is connected to the float 113. The filler fiber filaments 1122 can quickly enrich the dominant bacterial species. Under the premise of adding bacterial species, the bio-rope filler 112 can quickly form a biofilm. This structure can achieve internal anoxic and external aerobic conditions. Due to the transfer effect, it plays a role in simultaneous nitrification and denitrification, effectively removing organic matter. Furthermore, the bio-rope filler 112 can be made of a material with good adsorption properties and biocompatibility. For example, the filler fiber filaments can be a combination of polypropylene filaments (which can be used as support filaments) commonly used in the prior art and polypropylene or modified polypropylene fiber functional filaments. The appearance simulates the shape of natural aquatic plants and is in the form of slender strips. The filler fiber with a microporous structure has abundant micropores and rough texture on its surface, which can increase the surface area in contact with the water body, which is conducive to the attachment and growth of microorganisms. The effective diameter, installation height and installation spacing of the bio-rope filler are determined according to the actual situation on site. The height is generally 0.5-1m, and the spacing is generally 0.4-0.6m. In other embodiments, the bio-rope filler can be replaced with SJ brand patented high-efficiency denitrification filler, or other traditional fillers. In this example, the pure biofilm method is used to efficiently remove organic matter. Compared with ordinary aquatic plants, the bionic aquatic plants have better effects and ensure stable management throughout the year.

[0044] In this example, the bionic aquatic plant filler system 1 includes multiple groups of bionic aquatic plant filler components 10 arranged in parallel. According to the structural design of this example, even if multiple groups are set, problems such as entanglement and accumulation that are prone to occur in the filler system will basically not occur.

[0045] The bionic aquatic plant filler system 1 also includes an aeration component, which includes an aeration main pipe 21 and multiple aeration mechanisms 22. The above-mentioned multiple aeration mechanisms 22 are evenly distributed on the surrounding side of the above-mentioned at least one group of bionic aquatic plant filler components 10. The aeration mechanism 22 includes an aeration support frame and an aeration counterweight 222 and an aeration branch pipe 223 respectively arranged on the aeration support frame. The aeration branch pipe 223 is connected to the aeration main pipe 21; the aeration counterweight 222 is arranged at the bottom of the aeration support frame, and the aeration counterweight 222 can make the aeration mechanism immersed in water. The aeration branch pipe 223 is arranged at the top of the aeration support frame. Specifically, the aeration branch pipe 223 can be coiled on the aeration support frame. The aeration branch pipe 223 is aerated according to the conventional setting method of opening aeration holes. The aeration branch pipe 223 is connected to the aeration main pipe 21 through an aeration joint 2231.

[0046] In this example, the aeration support frame includes a bottom support frame 2211 , a top support frame 2212 and a connecting rod 2213 connected between the bottom support frame 2211 and the top support frame 2212 . The orthographic projection of the top support frame 2212 is located within the orthographic projection range of the bottom support frame 2211 .

[0047] Furthermore, the length of the chain 111 should not be too long. In this example, it is designed to be 5-10 meters. The appropriate length ensures that the aeration mechanisms 22 can be installed between the bionic waterweed filler assemblies 10, and the aeration mechanisms 22 can be installed in a staggered manner. The installation spacing between each group of bionic waterweed filler assemblies can be 0.5-1 meter. They are evenly arranged in the river channel according to the width of the river channel. Aeration mechanisms are placed at appropriate positions in each group of filler to provide oxygen and agitation to the water.

[0048] In this example, the bionic aquatic plant filler system 1 also includes a holding pool 30 capable of controlling the water level. The at least one set of bionic aquatic plant filler assemblies 10 described above is placed within the holding pool 30, which is formed by a portion of the river channel. Furthermore, the holding pool is formed by constructing intercepting dams upstream and downstream of the river channel. This facilitates controlling the water level within the holding pool, minimizing water level fluctuations and keeping the filler submerged. This prevents the system from being exposed above the water surface during dry seasons, ensuring the continuity and stability of the treatment effect.

[0049] Furthermore, the chain 111 extends along the water flow direction of the holding tank 30 , and the counterweight 114 is located upstream of the water flow direction of the holding tank 30 .

[0050] Specifically, in the management of narrow river channels, especially those with hard riverbeds 40, the specific implementation process is as follows:

[0051] First, an intercepting dam can be built at the upstream and downstream sections of the river to form a holding pool 30, so that the liquid level is maintained at about 1.2m. Water level changes and management needs should be taken into consideration as much as possible to ensure that the water level is appropriate during the dry season and the facilities operate normally. The bio-rope filler 112 is made into 1m pieces, and a float 113 is installed on the upper end of the bio-rope filler 112, which can be a foam float. The float 113 is fixed to the center rope of the bio-rope filler 112 with a connecting rope. The bottom of the bio-rope filler 112 is fixed to the stainless steel chain by a connecting rope or a nylon tie. The iron chain has a fixed length of 10m, and the bio-rope filler is fixed to the iron chain at a spacing of 0.1m. Then, about 95 bio-rope fillers are fixed on the iron chain, and the remaining ends of the iron chain are fixed to the counterweight block. In this way, the bionic water grass filler assembly 10 is completed. When it is deployed, it can be installed against the water flow, which helps to avoid entanglement and ensure stability.

[0052] In a 10m wide river channel, nine groups of biomimetic waterweed packing assemblies 10 are arranged, with each group spaced 1m apart. This helps prevent entanglement and forms a biomimetic waterweed packing assembly cluster. If multiple biomimetic waterweed packing assembly clusters are to be arranged, they can also be spaced apart, for example, 5m apart. In addition to being located at the outermost ends, aeration mechanisms 22 can also be installed between individual bio-rope packings, between individual biomimetic waterweed packing assemblies, or between groups of biomimetic waterweed packing assemblies. Appropriate aeration mechanisms are selected based on the specific conditions of the river channel, with their placement and quantity determined to ensure uniform oxygenation and agitation, promoting water circulation and pollutant decomposition.

[0053] After deployment is complete, specific bacterial strains are precisely added to the bio-rope filler 112. The strain is selected based on the level and characteristics of the water pollution, and the dosage is calculated to ensure rapid biofilm formation and enhance degradation capacity. Throughout the treatment process, parameters such as water level, flow, dissolved oxygen, and water quality are monitored in real time, and measures are adjusted promptly based on the results to ensure the desired results are achieved.

[0054] In summary, the utility model innovatively provides a new type of bionic aquatic plant filler system. Through the design of the top float and the bottom chain and counterweight block, the biological rope filler can be stably set in the river to be treated. In particular, the design of the float and the bottom chain and counterweight block makes the biological rope filler suspended below the water surface, which does not affect the overall appearance of the river channel, while reducing the interference with the natural ecology of the river channel, providing a more favorable growth environment for microorganisms, thereby significantly improving the removal efficiency and treatment quality of pollutants, and can also avoid problems such as entanglement and accumulation that are prone to occur in traditional filler systems; in addition, the bionic aquatic plant filler system of the utility model abandons complex and expensive fixing methods, such as expansion bolts or fixed piles, and adopts a simple and effective combination of iron chains and counterweight blocks, which greatly reduces material and installation costs; and the overall design is simple, the installation steps are simplified, no pumping construction is required, water operations can be carried out, and no complicated construction operations are required, which improves installation efficiency and shortens the construction period, and is suitable for ecological management of narrow rivers.

[0055] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
