Ecological floating island and building method thereof

Abstract

The invention discloses an ecological floating island and a building method thereof, the island comprises a floating island unit outline border (1), an outline border cover (2), floating-body filler (3), planting cups (4) and planting pipes (5). Under the synergic action of the floating-body filler (3), microorganisms growing on the floating-body filler (3) and plant root systems, optimal biological balance can be established, so that polluted water body can be treated continuously; meanwhile, the ecological floating island of the invention can be suitable for various plants, and crop rotation or interplanting can be carried out to achieve the effects of stereo planting and four-season planting, and treatment effect and landscape effect can be kept all year round; by adopting the planting cups (4) and the planting pipes (5), the workload for building the ecological floating island can be reduced and the survival rate of the cultivated plants is improved; in addition, the ecological floating island of the invention can be assembled in a laminating way, thus improving the pollution control efficiency greatly.

Description

Technical field: [0001] The invention relates to the field of water body pollution control, in particular to an ecological floating island used for water body control in rivers, lakes, small domestic sewage and other water areas and a construction method thereof. Background technique: [0002] In recent years, water pollution has increasingly become a topic of concern. For example, in recent years, the water bodies in the rivers of cities and towns have been polluted by the arbitrary discharge of industrial and agricultural production sewage, which has posed a great threat to the drinking water of residents. What is more serious is that some major water pollution incidents have occurred, which makes people feel sad and sad. worry. According to the "2007 Environmental Status Bulletin" issued by the State Environmental Protection Administration, the water pollution situation is still severe. [0003] Water pollution in lakes, reservoirs, and urban rivers is mainly caused by ...

Problems solved by technology

Although the state has stepped up efforts in water environment governance, overall, the trend of water environment deterioration has not yet been fundamentally reversed

[0004] At present, ecological floating islands have been widely used in reservoirs, lakes, ponds and other waters because of their comprehensive functions of purifying water quality, creating living spaces for organisms, improving landscapes, and reducing waves. However, the existing ecological floating islands have a single function, only The plants planted on the ecological floating island and the microorganisms attached to the plant roots can absorb and transform pollutants, and other devices on the ecological floating island have no function of treating polluted water bodies; the floating bodies of the existing ecological floating islands generally use foam, plastic bottles, etc. Planted on the top of foam and plastic bottles, but the mortality rate of plants is high, and it is not conducive to the normal growth of plants. In addition, the above-mentioned foam and plastic bottles have also brought secondary pollution to water bodies; Restrictions, planting species are single, generally only emergent plants can be planted, and most of them are directly sown or planted on floating islands, resulting in high plant mortality, inconvenient operation, slow reflection of landscape effects and sewage treatment effects, and difficult maintenance and management
