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, relates to a device capable of lifting and lowering a plant sink block and a floating block three-dimensionally coupled to purify water quality, and in particular to a device that can adjust the flow of the sink block and the floating block 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 the water body, it can provide a habitat for aquatic organisms, and it is a device that is beneficial to the health of the aquatic ecosystem. Background technique [0002] At present, the problem of water pollution in rivers and lakes in my country is serious. Many lakes are eutrophic, the water ecosystem is continuously degraded, and the self-purification ability of water bodies is continuously weakened. How to improve the self-purification capacity of river...

AI Technical Summary

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 bodies is much lower than the light compensation point of submerged plants, and the photosynthesis of submerged plants is less than that of respiration. , its survival is inhibited and eventually leads to the demise of the plant community, and it is very difficult to restore submerged plants under this environmental condition

Therefore, the growth of submerged plants in polluted water bodies and the restoration of submerged vegetation are difficult issues in the ecological restoration of water bodies. At present, there is no very effective technology to solve the problems of underwater light conditions in the process of restoring submerged vegetation in polluted water bodies. , which is also the main technical problem faced in the application of ecological sedimentation bed technology
