Description

Technical Field

[0001] The utility model relates to the technical field of ecological floating wetlands, in particular to an ecological composite floating artificial wetland. Background Art

[0002] Ecological floating island wetland technology is a new type of water ecological restoration method. It creates an environment suitable for the growth of aquatic plants in the water by imitating the functions of natural wetlands. It has been widely used in the treatment of seriously polluted rivers and lakes in cities. The aquatic vegetation cultivated on these floating island wetlands has the ability to absorb harmful components and promote sewage purification, which plays a positive role in improving water quality and repairing water ecosystems.

[0003] Despite this, traditional floating island wetlands often use disc-shaped hollow plastic structures or composite fiber modules, which are laid horizontally on the water surface. Because they use lightweight materials and are thin, traditional floating island wetlands have weak carrying capacity and are not suitable for planting large plants or bearing large biological loads. Especially in the frozen areas of the north, when rivers and lakes freeze in winter, the roots of traditional floating island wetland emergent plants, floating plants and other plants are directly wrapped in ice, making it difficult for them to survive and need to be replaced and replanted every year. In addition, traditional floating island wetland materials are prone to brittleness below zero degrees, are intolerant to ice expansion, and are prone to aging and damage. If the floating island material or plant management is not good, it may make the floating island itself a new source of water pollution, causing environmental problems. In addition, the materials and structural designs of traditional floating island wetlands may show insufficient stability when encountering natural phenomena such as strong winds, huge waves, and freezing. The floating bodies of traditional floating island wetlands will be pierced by plant roots, and over time, the buoyancy will gradually decrease, resulting in sinking problems. In addition, the construction and maintenance costs are relatively high, involving expenses such as floating island material costs, plant planting, and regular maintenance.

[0004] In summary, although ecological floating island technology has many benefits, the challenges and limitations it faces cannot be ignored. In order to improve its application efficiency and sustainability in the field of water ecological restoration, it is urgent to continuously optimize and strengthen technology development, management practices and social awareness.

[0026] The principle of this embodiment is:

[0027] When in use, the ecological composite floating wetland matrix 2 is fixed and supported as a whole by the floating bed frame 1 and the pontoon 3, wherein the ecological composite floating wetland matrix 2 is rectangular or square, with long wetland islands on both sides, and submerged areas and wet areas in the middle and around. The submerged area is 15cm-30cm underwater, the wetland island is 20cm-60cm above the water surface, and the rest is the wet area. The ecological composite floating wetland matrix 2 adopts the interweaving connection method of low-temperature-resistant and anti-aging filament woven polyester fiber and plant fiber, which has sufficient thickness and thermal insulation, is conducive to the expansion and puncture of plant roots, and the roots of plants will not be frozen in winter, ensuring the overwintering of plants, providing plant regeneration ability and service life, and no need to replace and replant every year. The plant regeneration rate is greater than 95%. When the plant root system is formed, the durability of the ecological composite floating wetland matrix 2 is enhanced, and the problem of broken wires caused by viscose aging is eliminated. It is easy to form an integrated structure, which can withstand wind and waves and the impact of large water flows;

[0028] Then, buoys 3 are arranged on the four sides of the bottom of the floating bed frame 1, and an inflatable bag is installed inside the buoy 3. The air pipe 701 is connected to the inflatable bag, and the air pipe 701 extends to the edge of the wetland. Then, the valve 11 can be opened or closed as needed to control the water level inside the buoy 3 and the floating height of the wetland. Therefore, the weight brought by the accumulation of organisms is offset by the adjustable static buoyancy. Therefore, under the multiple buoyancy effects of the ecological composite floating wetland matrix 2, the buoy 3 and the floating bed frame 1, the ecological composite floating artificial wetland has a large floating wetland area, large buoyancy, can be manned, and is convenient for initial planting and subsequent maintenance. Finally, an aeration system 7 is arranged on the edge of the floating bed frame 1 to form a complete underwater oxygen supply facility, which provides sufficient dissolved oxygen content for the root system and biofilm at the bottom of the wetland, increases the dissolved oxygen content of the water body around the artificial wetland, and avoids fish deaths and black and smelly water.

[0029] To sum up: this ecologically complex floating artificial wetland overcomes the need for repeated replanting of plants, spreading of fungicides and pruning of plants required by traditional floating island ecological restoration measures. By strengthening the splicing combination of wetland modules, the functions of plants, microorganisms and animals in damaged water bodies are strengthened. Through the synergistic effect of microorganisms, plants and ecosystems, the nitrogen and phosphorus content of water bodies is reduced, the growth of algae is controlled, and the aquatic biological population is quickly restored. The ecological purification of floating wetlands is non-toxic and has no secondary pollution, which improves the water quality of polluted water bodies. The ecologically complex floating artificial wetland not only purifies water quality, but also provides habitats for birds, fish, shrimps and crabs, forming a stable ecological chain, constructing a micro-ecological system with a virtuous cycle of producers-consumers-decomposers, enhancing the self-purification function and anti-interference ability of water bodies, realizing in-situ deep purification of water bodies and water ecological restoration, and at the same time forming a beautiful riverside landscape.
