Description

Technical Field

[0001] The utility model relates to the technical field of river and lake water environment treatment, in particular to an ecological island. Background Technique

[0002] An ecological island is an artificial, organic, and enclosed ecosystem, usually designed to simulate various functions and cycles of a natural ecosystem in a relatively small space, and usually treats the river and lake water environment through ecology. In the river and lake basin environment, traditional artificial islands often aim at construction and lack ecological sustainability. Therefore, it is necessary to seek an artificial ecological island that can not only meet the needs of human activities but also maintain ecological balance.

[0003] Currently, the main factors affecting the water quality of river and lake waters are nutrients such as COD, nitrogen, and phosphorus. These substances will consume a large amount of dissolved oxygen in the water, resulting in water hypoxia, anaerobic blackening and odor. However, the main treatment methods for river and lake basin waters are source control and pollution interception, oxygenation measures for water bodies to increase the dissolved oxygen concentration in the water, adding drugs to precipitate some pollutants by chemical methods, and ecological treatment measures, etc. When these measures are used for treatment, there are problems such as energy consumption in the aeration and oxygenation measures, or the introduction of microbial strains will impact the ecological balance of the current water body.

[0004] The invention with the publication number CN108046437A proposes a river channel artificial ecological island, including: a substrate functional area and an ecological slope protection area; the ecological slope protection area is arranged outside the substrate functional area; the substrate functional area includes a river sand layer, a first gravel layer, a second gravel layer, a volcanic rock layer, and a soil layer from bottom to top; the ecological slope protection area includes a geotextile, a grid fence, and a sediment layer from inside to outside; aquatic plants are planted in both the sediment layer and the soil layer; a water pipe is arranged in the first gravel layer, and the water pipe passes through the ecological slope protection area and is connected to the external water body. However, the above ecological island is not convenient for absorbing organic pollutants and nutrients such as nitrogen and phosphorus in the water by planting plants. Therefore, this application proposes an ecological island to solve the above problems. Content of the Utility Model

Among them, the submerged plants can be selected to plant Ceratophyllum demersum, Vallisneria natans, etc., and the emergent plants can be selected to plant Phragmites australis, Typha orientalis, Canna indica, etc. By planting these plants, nitrogen, phosphorus and other nutrients in the water can be well absorbed, playing a role in purifying the water environment. At the same time, since the top of the connecting platform 21 is a flat surface, the lake area side platform 2 plays a role in strengthening the first lake area side slope 1 and the second lake area side slope 3, thereby increasing the structural stability of the ecological island of the present application.

Among them, both the first lake-side slope 1 and the lake-side platform 2 are completely immersed in water. The water-entry slope 311 of the second lake-side slope 3 is immersed in water, and the water-exit slope 312 is located outside the water level. Therefore, submerged plants are planted on both the first top slope 11 and the connecting platform 21. In the second top slope 31, submerged plants are planted on the water-entry slope 311, and emergent plants are planted on the water-exit slope 312. Among them, the submerged plants can be selected to plant Ceratophyllum demersum, Vallisneria natans, etc., and the emergent plants can be selected to plant Phragmites australis, Typha orientalis, Canna indica, etc. By planting these plants, nitrogen, phosphorus and other nutrient elements in the water can be well absorbed, playing a role in purifying the water environment. At the same time, since the top of the connecting platform 21 is flat, the lake-side platform 2 plays a role in strengthening the first lake-side slope 1 and the second lake-side slope 3, thereby increasing the structural stability of the ecological island of this application. The stabilizing piles 5 are provided to reinforce the lake-side platform 2. By providing the island-forming side support area 4, the second lake-side slope 3 and the planting soil 6 can be supported.
