[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] The utility model provides a composite artificial waterweed, comprising a floating ball 1. Figure 1 As shown, the buoy 1 is in contact with the water surface and floats on the water surface. The buoy 1 is made of polyethylene, polypropylene or foam material, and is used to bear the weight of the entire artificial aquatic plant and accessories, so that the product can be suspended in the water and fully contact the water body. Multiple buoys 1 can be connected in series.

[0026] The float 1 is fixedly connected to a center rope 2 through an anti-ultraviolet nylon rope. The center rope 2 goes deep into the water body, and the end of the center rope 2 away from the float 1 is fixedly connected to the bottom counterweight module 6 through a nylon rope. The bottom counterweight module 6 is selected according to the actual product weight. The bottom counterweight module 6 is made of stainless steel bolts or prefabricated cement piers to ensure the stability of the overall composite artificial water grass and prevent it from being washed away or moved by water flow changes.

[0027] The outer braided fiber bundle 3 is woven and fixedly connected to the center rope 2, and the weaving form is cross-weaving to ensure that the connection is tight and will not fall off. The outer braided fiber bundle 3 is formed by weaving and fixing a plurality of annular fibers, and the weaving form is a serpentine braid-belt weaving method to construct a larger space for microbial reproduction. The outer diameter of the annular fiber is between 40 and 80 mm and can be selected according to demand. The outer braided fiber bundle 3 adopts graphene derivative modification technology, hydrophilic material modification technology and bio-enzyme composite technology, which effectively shortens the biofilm period, effectively improves the specific surface area of ​​the carrier material, strengthens the adsorption performance of the material, and increases the attachment area of ​​microorganisms, thereby increasing the biomass of the biofilm and improving the unit load processing capacity.

[0028] A plurality of ecologically guided slow-release microorganisms 4 are fixedly mounted on the central rope 2. The ecologically guided slow-release microorganisms 4 include a first mesh bag and slow-release microorganisms. The first mesh bag is sewn and fixedly connected to the central rope 2. The first mesh bag is a polymerized slow-release matrix. The slow-release microorganisms are attached to the first mesh bag. After the slow-release microorganisms in the first mesh bag come into contact with water, they continuously release the microorganisms, and the carriers to which they are attached gradually dissolve and eventually disappear.

[0029] A number of slow-release oxygen-enhancing particles 5 are fixedly mounted on the central rope 2. The slow-release oxygen-enhancing particles 5 include a second mesh bag and oxygen-enhancing particles. The second mesh bag is sewn and fixedly connected to the central rope 2. The oxygen-enhancing particles are slow-release and attached to the second mesh bag. After the oxygen-enhancing particles in the second mesh bag come into contact with water, they continuously release oxygen. After the oxygen dissolves in water, it is provided for the reproduction of aerobic microorganisms on the artificial aquatic plants and is used to strengthen the formation of microbial film. The particles gradually dissolve and eventually disappear.

[0030] The ecologically guided slow-release microorganisms 4 and the slow-release oxygen-enhancing particles 5 are both covered by the outer braided fiber bundle 3 .

[0031] Working principle:

[0032] When in use, the site to be treated is selected and the installation area is determined. The composite artificial aquatic plants are pre-assembled on the shore, and the buoy 1 and the center rope 2 are connected with nylon ropes. At the same time, the center rope 2 and the bottom counterweight module 6 are connected with nylon ropes. All connections should be ensured to be tight. Among them, the ecologically guided slow-release microorganisms 4 and the slow-release oxygen-enhancing particles 5 should be sewn and fixed according to the design requirements before leaving the factory. After the pre-assembly on the shore is completed, the artificial aquatic plants are placed in the designated area according to the project requirements. After placement, the artificial aquatic plants are ensured to be in a vertically suspended state as a whole, and the outer woven fiber bundles 3 are ensured to be in full contact with the water body.

[0033] After the artificial aquatic plants are placed and arranged, the slow-release oxygen-enhancing particles 5 will react with the water, continuously produce oxygen, rapidly increase the dissolved oxygen level of the surrounding water body, and construct different dissolved oxygen intervals to create good conditions for the reproduction and growth of microorganisms. At the same time, after the ecologically guided slow-release microorganisms 4 contact the water body, they gradually adapt to and continuously release beneficial microorganisms. In the environment created by the slow-release oxygen-enhancing particles 5, and due to the biological enzymes they carry, they provide sufficient nutrition for the reproduction of microorganisms and promote the diffusion and release of microorganisms. After the outer braided fiber bundle 3 is treated with graphene derivative modification technology, hydrophilic material modification technology and biological enzyme composite technology, it has a large specific surface area. After the microorganisms of the ecologically guided slow-release microorganisms 4 diffuse, they will preferentially adsorb and attach to the surface of the outer braided fiber bundle 3, gradually forming an anaerobic-facultative-aerobic-aerobic biofilm structure from the inside to the outside of the carrier, and continuously reproduce and grow. The biofilm continuously absorbs and degrades organic pollutants and nitrogen and phosphorus nutrients in the water through different microbial colonies, thereby effectively purifying the water quality.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
