Problems solved by technology

Most urban landscape water bodies are closed and semi-closed water bodies. Their application encounters two problems of water quality maintenance and water balance. Eutrophication of water bodies has become the biggest problem in their ecological restoration. Traditional methods such as mechanical filtration and dredging sediment have investment Disadvantages such as large size, high maintenance cost and unfavorable to the healthy development of water ecosystem

Abstract

The invention discloses an ecological restoration system for urban landscape water and a restoration method thereof. The system comprises a water part, a biology floating island system on the surface of the water, an animal ecological system below the water, and a water flowing device installed at the bottom of the water, the systematic ecological restoration system in which microorganisms, animals, plants and people participate is formed, all components cooperate with one another, and the ecological restoration system having a good restoration effect on the urban landscape water and the restoration method are effectively formed. The system and the method have the following advantages that firstly, zero pollution emission is achieved by adjusting measure according to local conditions; the system and the method can save energy, and are efficient, simple in technology, capable of saving investment, short in construction period and the like, and a good landscape effect is achieved; thirdly, ecological community is localized, biological diversity is high, the ecological system is stable, ecological risks are avoided, and the ecological environment quality is improved; fourthly, the adaptability to fluctuation of pollution load is high, influences to the environment are small, secondary pollution is avoided or pollutant transfer is avoided, and the pollutant concentration can be reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of environmental protection and governance, in particular to an ecological restoration system for urban landscape water bodies and a restoration method thereof. Background technique [0002] At present, the ecological restoration technology in China mainly refers to restoring or rebuilding the degraded ecosystem to the extent that it can be used by human beings to the maximum extent, while maintaining the necessary functions of the system, and using various means under the premise of following the laws of nature. bring the system to a self-sustaining state. Water ecological restoration technology has been applied to medium and large rivers, wetlands, and lakes in my country to restore their degraded aquatic ecosystems and make them more ecologically tolerant. The ecological restoration model applied on a large scale has gradually matured, but there are still some problems, such as the technology is not flexible enoug...
