Multilayer three-dimensional ecological floating bed with hanging elastic packing

Abstract

A multilayer three-dimensional ecological floating bed with hanging elastic packing comprises an aquatic plant region, a floating bed carrier region and a three-dimensional elastic packing region, wherein the floating bed carrier region is located below the aquatic plant region and used for absorbing nutrient substances in water for aquatic plants in the aquatic plant region; the three-dimensional elastic packing region is hung at the bottom of the floating bed carrier region and used for providing an attachment and proliferation carrier for microbes in water to prevent the microbes from being caught and eaten by protozoa. According to the multilayer three-dimensional ecological floating bed, an ecological floating island technology and a biological membrane technology are combined, the growth requirements of plants are met to the utmost extent by virtue of the characteristic that the carrier layer of the floating bed can adsorb nutrient elements such as nitrogen and phosphorus, and organic pollutants in water can be removed by a biological membrane on the surface of the three-dimensional packing hung at the bottom of the carrier layer so as to realize repairing of water pollution of a water body eventually. The multilayer three-dimensional ecological floating bed is mainly suitable for ecological restoration of eutrophication of rivers, lakes and other landscape water bodies, can meet esthetic effects, and has a certain interception effect on suspended matters; and meanwhile the multilayer three-dimensional ecological floating bed achieves a high removal effect on nitrogen and phosphorus, and has the advantage of low running cost.

Description

technical field [0001] The invention relates to the technical field of water environment ecological restoration, and is a novel composite artificial floating island, which is suitable for the treatment of rivers, lakes and other water bodies with landscape requirements, and specifically relates to a multi-level three-dimensional ecological floating bed with elastic fillers suspended. Background technique [0002] In recent years, with the rapid development of the economy, the sewage treatment project is relatively backward compared with the urban development speed, and the problem of water pollution has become increasingly prominent, especially for rivers and lakes with landscape functions, due to their poor fluidity and low self-purification ability, water body eutrophication is serious . Water eutrophication refers to the excessive discharge of nutrients such as nitrogen and phosphorus into natural water bodies, which causes excessive growth of algae and other phytoplankto...
