Description

An enhanced composite ecological floating island

technical field

The invention relates to the fields of water conservancy, environment and ecological restoration engineering, and in particular to an enhanced composite ecological floating island used for purification and ecological restoration of rivers, lakes, reservoirs, landscape water bodies, small domestic sewage and other water areas and water bodies.

Background technique

Using ecological technology to restore the water quality of rivers and lakes is an economical and effective method, which has been widely used in developed countries and domestic economically developed areas. Ecological technology mainly refers to artificial wetlands, ecological floating islands, etc., which are technologies that promote the restoration of the ecological balance of water bodies composed of microorganisms, aquatic plants, and aquatic animals. Urban rivers, lakes and reservoirs are affected by land use and water level changes, and the application of constructed wetland technology is limited. The artificial ecological floating island technology is not limited by the change of water level, and can be directly arranged on the water surface, which is convenient for maintenance and management.

The traditional artificial ecological floating island technology is to plant higher aquatic plants or improved terrestrial plants on the water surface of eutrophic waters through soilless cultivation technology in accordance with the laws of nature itself, and through the absorption and adsorption of plant roots and the mutual restraint mechanism of species competition , reduce and enrich the nitrogen, phosphorus and harmful substances in the water body, so as to achieve the effect of purifying the water quality, and at the same time create a water landscape.

Traditional ecological floating islands mainly rely on the absorption of plant roots and the microorganisms attached to the roots to reduce the nutrients in the water body. Therefore, the water purification speed is slow and the purification ability is not strong, and the area to achieve a certain load removal is relatively large. At the same time, the selection of ecological floating islands includes bamboo, waste tires, foam, plastic, etc. Some floating islands are also equipped with solar photovoltaic systems, aeration systems, circulation systems, etc., and their construction methods are relatively complicated, or the production cost is high, or The low purification efficiency limits its application.
