This device can restore and improve the ecological environment of landscape lakes by improving lake water quality through the synergistic effect of aquatic plants and microorganisms, thus achieving efficient restoration of the lake ecosystem, restoring its balance, and improving its stability and sustainability.

[0034] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0035] Figure 1 This is a schematic diagram of the structure of a landscape lake management device according to an embodiment of this application, as shown below. Figure 1As shown, the landscape lake management device includes at least an emergent plant planting area 10, an auxiliary management component, and a submerged plant planting area 50. The auxiliary management component is located at the bottom of the emergent plant planting area 10 and includes a microbial culture area 20, a spraying component, and a buoyancy component 40. The buoyancy component 40 is arranged circumferentially along the outer periphery of the emergent plant planting area 10. The spraying inlet of the spraying component is connected to the microbial culture area 20, and the spraying outlet of the spraying component is located in the landscape lake water to spray microorganisms into the landscape lake water. The submerged plant planting area 50 is located at the bottom of the auxiliary management component.

[0036] like Figure 1 As shown, the emergent plant planting area 10 and the submerged plant planting area 50 are located at the top and bottom of the auxiliary treatment component, respectively. The emergent plant planting area 10 is used to plant emergent plants, and the submerged plant planting area 50 is used to plant submerged plants. The submerged plant planting area 50 and the emergent plant planting area 10 can be collectively referred to as the aquatic plant fixing area, where emergent plants and submerged plants can be collectively referred to as aquatic plants. The buoyancy component 40 is used to provide buoyancy for the device, allowing the stems and leaves of the emergent plants to emerge above the water surface. In addition, the microbial culture area 20 is used to cultivate microorganisms, and the spraying component is used to spray the microorganisms in the microbial culture area 20 into the landscape lake water. In this embodiment, aquatic plants can absorb nutrients such as nitrogen and phosphorus in the water and convert them into substances needed for their own growth to maintain and ensure their own growth and survival. They also produce secondary metabolites (allelochemicals) to inhibit algal blooms. While secreting substances to inhibit algal growth, they also become a site for microbial attachment. Microorganisms sprayed into the landscape lake water via the spraying assembly can decompose organic pollutants into carbon dioxide, water, and inorganic matter, and can also mineralize organic compounds to provide nutrients for plants. Therefore, this landscape lake treatment device, through the interaction between aquatic plants and microorganisms, improves the resilience and diversity of the lake ecosystem at a low cost, has high renewability, can achieve sustainable development, and has significant treatment effects.

[0037] Specifically, both the emergent plant planting area 10 and the submerged plant planting area 50 can be cylindrical in shape, thus forming a cylindrical structure. In addition, an ecological cage 70 can also be installed at the bottom of the submerged plant planting area 50. It is understood that limiting the shape of the emergent plant planting area 10 and the submerged plant planting area 50 to cylindrical is merely an example; in other embodiments, the emergent plant planting area 10 and the submerged plant planting area 50 can also be other shapes, such as square.

[0038] Furthermore, both the emergent plant planting area 10 and the submerged plant planting area 50 have multiple grids, and the grid spacing of the emergent plant planting area 10 is greater than that of the submerged plant planting area 50. In this embodiment, both the emergent plant planting area 10 and the submerged plant planting area 50 are set as grid structures to ensure the stable growth of submerged and emergent plants within the aquatic plant fixed area; for example, the grid size (also called grid spacing) of the emergent plant planting area 10 is larger to accommodate the thicker roots of emergent plants; while the grid size of the submerged plant planting area 50 is smaller to accommodate the thinner roots of submerged plants.

[0039] Specifically, considering the climatic differences of landscape lakes in different regions, the selected aquatic plants should be able to adapt to local temperature changes. For example, in northern regions, cold-resistant aquatic plants should be selected, while in high-temperature southern regions, heat-resistant aquatic plants should be selected. Furthermore, priority should be given to plants that have efficient absorption and degradation capabilities for pollutants such as nitrogen, phosphorus, heavy metals, and organic matter, as well as significant allelopathic effects. At the same time, it is important to ensure that the selected aquatic plants pose no risk of biological invasion, will not damage the local ecosystem, and also possess ornamental value.

[0040] Furthermore, the microorganisms within the microbial cultivation zone 20 can be solid microbial particles. These particles can be made from composite microbial agents with highly efficient organic pollutant degradation capabilities, and their porous surface increases the contact area between the microorganisms and the water, thereby improving decomposition efficiency. This landscape lake treatment device can introduce different microbial species under varying sources of microbial pollution. For example, when nitrogen (N) is the primary pollutant, nitrifying and denitrifying bacteria such as nitrite-oxidizing bacteria, nitrifying bacteria, Pseudomonas, and Bacillus can be used. When phosphorus (P) is the primary pollutant, polyphosphate-accumulating bacteria can be used.

[0041] In one embodiment, the landscape lake management device further includes a filter assembly, the top of which is connected to the bottom of the emergent plant planting area 10, and the microbial culture area 20 is disposed outside the filter assembly. Figure 2 As shown, the top and bottom ends of the filter assembly are connected to the bottom plate of the emergent plant planting area 10 and the top plate of the submerged plant planting area 50, respectively. At this time, the filter assembly is located between the emergent plant planting area 10 and the submerged plant planting area 50, and is positioned in the middle of the bottom plate of the emergent plant planting area 10 and the top plate of the submerged plant planting area 50. For ease of description, the bottom plate of the emergent plant planting area 10 and the top plate of the submerged plant planting area 50 are collectively referred to as partition plate 80. Figure 2As can be seen, the filter assembly is symmetrically arranged front-to-back with respect to the center plane of the partition 80, and microbial culture areas 20 are provided on both sides of the filter assembly, which are also symmetrically arranged front-to-back with respect to the center plane of the partition 80. Each microbial culture area 20 on each side of the filter assembly includes multiple microbial culture boxes 21, and correspondingly, the spray inlet of the spray assembly is connected to each microbial culture box 21.

[0042] Furthermore, the filtration assembly includes multiple drawer-type filter screens 60, which are arranged parallel to each other along a direction perpendicular to the height of the landscape lake treatment device. For example... Figure 2 As shown, the bottom surfaces of the multi-layer drawer-type filter screen 60 are flush with each other, and the top surfaces of the multi-layer drawer-type filter screen 60 are also flush with each other. In this embodiment, the landscape lake water passes through each layer of drawer-type filter screen 60 in sequence to complete the filtration.

[0043] Specifically, the mesh size of the multi-layer drawer-type filter screen 60 gradually decreases. In this embodiment, the multi-layer drawer-type filter screen 60 is configured with filter screens of different sizes to filter debris of different sizes in the lake, thereby filtering the debris from large to small, preventing small-diameter debris from clogging the large-pore layer, improving filtration efficiency. During the movement of the device, algae, debris, etc. in the water are filtered by the drawer-type filter screen 60 and remain in the drawer corresponding to the filter screen of the appropriate size, thus efficiently filtering algae, debris, etc. in the water, reducing turbidity, and improving water visibility.

[0044] Furthermore, each drawer-type filter screen 60 can be individually disassembled or installed; specifically, each drawer-type filter screen 60 can be pulled up from the top or bottom during disassembly or installation. This structure allows each drawer-type filter screen 60 to support layered disassembly and cleaning, improving the ease of maintenance of the filter assembly. For example, the filter assembly includes four layers of drawer-type filter screens 60, which are respectively coarse filter (mesh size 5-10mm), medium filter (mesh size 1-5mm), fine filter (mesh size 0.1-1mm), and micro filter (mesh size <0.1mm). Specifically, the first layer of coarse filter screen is used to filter twigs, plastic bottles, etc., larger than 5mm; the second layer of medium filter screen is used to filter gravel, insect carcasses, etc., between 1-5mm in size; the third layer of fine filter screen is used to filter silt, algae flocs, etc., between 0.1-1mm in size; and the fourth layer of micro filter screen is used to filter colloids, plankton, etc., smaller than 0.1mm in size.

[0045] like Figure 2As shown, the microbial culture area 20 includes multiple microbial culture boxes 21, which are symmetrically arranged on both sides of the filter assembly. In this embodiment, three microbial culture boxes 21 are respectively provided on both sides of the filter assembly, and the microbial culture boxes 21 on both sides of the filter assembly are combined with the filter assembly to form a roughly cylindrical shape; the diameter of this cylinder can be equal to the diameter of the aquatic plant fixing area. In this embodiment, microorganisms can be cultivated in each microbial culture box 21 as needed. In order to spray the microorganisms in each microbial culture box 21 into the landscape lake water, each microbial culture box 21 is connected to the input end of the spraying assembly.

[0046] Furthermore, a microbial outlet is provided at the bottom of the microbial culture area 20. The spraying assembly includes a connecting pipe and a nozzle 31. The input end of the connecting pipe is connected to the microbial outlet, and the nozzle 31 is located at the output end of the connecting pipe. In this embodiment, one end of the connecting pipe is connected to the microbial culture area 20, and the other end is connected to the nozzle. That is, based on the connecting pipe, the microorganisms in the microbial culture area 20 can be sprayed into the landscape lake water through the nozzle.

[0047] In addition, the spraying assembly can be further equipped with a regulating valve, which can be installed on the connecting pipe. Based on the regulating valve, the spraying frequency and spray volume can be adjusted so that the microorganisms can be evenly distributed in the water body, thereby improving the decomposition efficiency of organic pollutants.

[0048] In some embodiments of this utility model, the landscape lake treatment device may further include an aeration component located above the nozzle 31, with its aeration outlet 32 ​​situated in the landscape lake water. The aeration component is used to introduce gas into the landscape lake water. Specifically, the aeration component may be located between the emergent plant planting area 10 and the submerged plant planting area 50, i.e., it may be fixed to the auxiliary treatment component. For example, the aeration component is located below the microbial cultivation area 20 and introduces air into the landscape lake water through the aeration outlet 32, increasing the dissolved oxygen content of the water, providing a suitable environment for the growth and metabolism of microorganisms, and simultaneously promoting the oxidative decomposition of organic pollutants, thus facilitating the spread of microorganisms.

[0049] For example, the materials for the emergent plant planting area 10 and the submerged plant planting area 50 can be plastic or fiberglass, the spraying component can be plastic, and the aeration component can be fiberglass. This embodiment uses high-strength, corrosion-resistant plastic or fiberglass materials for the emergent plant planting area 10 and the submerged plant planting area 50, which ensures the structural stability of the device, extends its service life, and reduces maintenance costs. Furthermore, due to the good water resistance and corrosion resistance of polymer materials such as plastics, they can also be used as materials for connecting pipes, valves, and other components of the spraying component. Fiber-reinforced composite materials such as fiberglass, due to their high strength, lightweight, and high design flexibility, can be used for the main frame of the aeration component, the pressure vessel of the spraying component, etc. Other components, such as fixing anchors, can be made of metals such as stainless steel.

[0050] In addition, the landscape lake management device may also include a temperature regulation component and a pH regulation component. The temperature regulation component is used to regulate the temperature within the microbial culture zone 20, and the pH regulation component is used to regulate the pH within the microbial culture zone 20. In this embodiment, the microbial culture zone 20 is equipped with temperature and pH regulation components, which can precisely adjust the temperature and pH of the culture environment according to the growth requirements of microorganisms, thereby promoting the large-scale reproduction of microorganisms.

[0051] The landscape lake treatment device disclosed in the above embodiments of this application is a remediation device capable of repairing pollution from heavy metals, organic pollutants, nitrogen, phosphorus, and other elements accumulated in landscape lakes. In use, the device is first fixed in place. Based on the characteristics of emergent and submerged plants, corresponding aquatic plants are fixed in the grid of the upper and lower aquatic plant fixing areas, respectively. Next, solid microbial particles are placed in the microbial culture box 21, and the temperature, pH, and other parameters of the microbial culture device are adjusted according to the growth requirements of the microorganisms. During operation, the aeration component continuously oxygenates the water, providing a favorable environment for the growth of microorganisms and aquatic plants. Microorganisms in the microbial culture area 20 multiply rapidly under suitable conditions and are evenly sprayed into the water through the spray component. Aquatic plants continuously absorb nutrients such as nitrogen and phosphorus from the water, inhibiting algae growth and providing attachment sites for microorganisms. Microorganisms decompose organic pollutants, converting them into nutrients usable by plants, achieving synergistic treatment of the landscape lake by aquatic plants and microorganisms. Furthermore, the number and distribution density of the landscape lake treatment device can be set according to the actual conditions of the landscape lake to achieve the best treatment effect. For example, in areas with severe pollution, the number of landscape lake treatment devices should be appropriately increased; in areas with slow water flow, the location of landscape lake treatment devices should be reasonably adjusted to ensure that microorganisms and aquatic plants can play their full role.

[0052] The landscape lake management device disclosed in the above embodiments of this utility model combines the degradation capabilities of microorganisms with the absorption, adsorption, and degradation effects of aquatic plants. It has low management costs, utilizes natural biological processes, and reduces the use of chemical agents and large-scale equipment. Furthermore, it is eco-friendly and will not cause secondary pollution to the lake environment. It also improves the resilience and diversity of the lake ecosystem, promotes the self-repair and sustainable development of the ecosystem, and significantly improves the lake water quality, increases water visibility, restores the landscape lake, and enhances the lake's ecological service functions.

[0053] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
