Multifunctional ecological floating island

Abstract

The present invention discloses a multifunctional ecological floating island. The floating island consists of several floating island units, which are fixed by the connecting plates in fastening; each floating island unit includes a hexagonal floating body frame and a provided with a plurality of planting baskets in the floating body frame; the planting basket is a regular hexagon basket with grid network on the bottom, and modified carbon fiber grass hangs below every corner of the basket; the modified carbon fiber grass is obtained by high temperature carbonization, activation, surface modification and microorganism fixing on carbon fibers; the bottom of each planting basket is covered with a filling substrate, and aquatic plants are planted on the substrate; and the plurality of planting baskets are arranged in the hexagonal floating body frame to form an integral structure. The ecological floating bed of the present invention has a stable hexagonal structure, combines floating island technology, micro-dosing technology and biological film together, and can adsorb, absorb and decompose various pollutants, beautify the urban river way or landscape water, and normally play strong power in winter.

Description

technical field [0001] The invention relates to an ecological floating island, in particular to a multifunctional ecological floating island for treating polluted water bodies. Background technique [0002] Eutrophication of water body has become a common phenomenon in water environment pollution in recent years. Due to the poor fluidity and low self-purification ability of lakes, urban rivers, and landscape water, eutrophication is relatively serious. As a traditional in-situ restoration measure for water environment, artificial ecological floating island has the advantages of convenient use, flexible application, and easy disassembly, so it has also been widely used. It has been highly praised for its ability to effectively reduce pollutants in water bodies through plant absorption and ecological regulation, and at the same time create water landscapes. However, the current ecological floating islands cannot be applied on a large scale due to some common problems. First...

Problems solved by technology

However, the current ecological floating islands cannot be applied on a large scale due to some common problems.

First, the floating bodies of floating islands mostly use conventional materials such as bamboo poles, foam boards, plastic boards, tires, stainless steel plus expanded polystyrene, special expanded polystyrene plus special synthetic resins, salted vinyl synthetic resins, and lightweight concrete. The material not only has a short service life (less than 2-3 years), but also easily causes secondary pollution; second, the function is relatively single. Generally, ecological floating islands mainly rely on aquatic plants to purify water, but in northern freezing areas, plants and floating bodies are both unable to survive the winter
