Description

Ecological bed that floats that adapts to river course water level variation

Technical Field

The application relates to the technical field of riverway water environment treatment and ecological restoration, in particular to an ecological floating bed adaptive to riverway water level change.

Background

The urban river is an important component of an urban ecological system and a watershed water system, and the form and the revetment type of the urban river are obviously changed along with the development of the economic society and the acceleration of the urbanization process in China. In the original river with a natural revetment, the two side surfaces and the bottom surface of the river tend to be smooth and straight so as to meet the requirements of urban flood control and drainage, and the characteristic characteristics of large water level amplitude and large flow speed in the flood season are that. The river water environment treatment depends on comprehensive technical means such as physics, chemistry, biology and the like, wherein the aquatic plant restoration and community reconstruction are important means for river ecological restoration and are also the key for maintaining the health of a river ecological system. As the bottom of the urban river is mostly a hard bottom or sludge with high organic matter content, the aquatic plant seeds are difficult to germinate and the seedlings are difficult to survive in a natural state.

In the current related technology, the planting and growing of aquatic plants depend on an ecological floating bed device. The method takes aquatic plants as main bodies, and fully utilizes the space ecological niche and the nutritional ecological niche of the river water body, thereby establishing a high-efficiency artificial ecosystem. The aquatic plants planted on the floating bed absorb organic matters in water by utilizing root systems for self growth, reduce pollutant indexes such as COD (chemical oxygen demand), total phosphorus and total nitrogen in the water body, and reduce pollution load in the water body, thereby achieving the effect of purifying water quality.
