Device for three-dimensional coupling and purification of water quality by lifting plant sinker and floater

Abstract

The invention provides a device for three-dimensional coupling and purification of water quality by lifting plant sinker and floater, and belongs to the fields of river and lake water body purification and ecological restoration. The device for three-dimensional coupling and purification of water quality by lifting the plant sinker and floater comprises a plant sinker, a plant floater, and a fixing and lifting regulation device. The device can regulate the positions of the plant sinker and the plant floater in the water body according to the water body transparency and water level change so as to achieve the effect of the growth of the aquatic plant and the three-dimensional coupling of the water quality, and a perfect aquatic ecosystem can be established through the plant sinker and the plant floater. A vegetation substrate block is favorable for recovery and replacement and the plant variety can be changed according to the growth cycles of the plants. The device has the advantages of stable structure, strong impact resistance, easy recovery, environment-friendly and pollution-free materials, factory production and convenient on-site construction, and is applied to in-situ purification and ecological restoration of rivers, lakes, and other open water bodies.

Description

technical field [0001] The invention relates to the field of water quality purification and ecological restoration of rivers and lakes, and relates to a device capable of three-dimensionally coupling and purifying water quality with plant sinkers and floating blocks, and in particular to a device that can adjust the sinker and floating blocks in the water body according to changes in water transparency and water level. In order to achieve the effect of three-dimensional coupling to purify water bodies, it can provide habitats for aquatic organisms and is beneficial to the health of aquatic ecosystems. Background technique [0002] At present, the water pollution of rivers and lakes in our country is serious. Many lakes are eutrophic, the water ecosystem is degrading, and the self-purification ability of water bodies is constantly weakening. How to improve the self-purification capacity of rivers and lakes, improve the deteriorating water environment of rivers and lakes, and ...

Problems solved by technology

[0003] At present, there are three main types of river and lake water purification and ecological restoration technologies used in the world: one is physical methods, that is, through engineering measures, mechanical algae removal, dredging of sediment, water diversion and dilution, etc. Emergency Measures Against Sudden Water Pollution

The second is chemical methods, such as adding chemical agents to kill algae, adding iron salts to promote the precipitation of phosphorus, adding lime to denitrify, etc., but the cost is large and it is easy to cause secondary pollution

However, in polluted water bodies, due to the large amount of suspended matter and organic matter that increases the absorption and scattering of light in the water body, the light intensity of the middle and lower water
