Floating wetland construction system for ecological restoration of surface water

Abstract

The invention discloses a floating wetland construction system for ecological restoration of surface water. The system comprises a composite fiber artificial floating island subsystem, a micro-electrolysis filler subsystem and a hygrophyte community, the composite fiber artificial floating island subsystem is formed by splicing a plurality of composite fiber floating island monomers; each composite fiber floating island monomer is an artificial floating island composed of a plant fiber layer and a polymer fiber layer wrapping the plant fiber layer. The planting holes are uniformly formed in the top surfaces of the synthetic fiber floating island single bodies; the planting holes are filled with matrix fillers; splicing connecting holes are formed in the edges of the two sides of each composite fiber floating island single body, binding components are connected between the opposite splicing connecting holes of the composite fiber floating island single bodies, and therefore the floatingwetland construction system with the good ecological landscape effect and capable of purifying water through cooperation of micro-electrolysis filler, microorganisms and hygrophytes is constructed.

Description

technical field [0001] The invention relates to the technical field of surface water purification and ecological restoration, in particular to a floating wetland construction system for surface water ecological restoration. Background technique [0002] With the acceleration of urbanization and industrialization in our country, surface water bodies such as rivers and lakes have been polluted to varying degrees, and the problems of water body pollution and eutrophication have become increasingly prominent. Under the background of the country's vigorous promotion of ecological civilization construction, my country's concept of surface water governance has gradually changed from engineering governance to ecological restoration. Ecological floating islands are an important means to effectively improve water quality, water ecology and landscape. [0003] At present, ecological floating islands are usually composed of polystyrene foam boards, PVC board pipes, assembled floating tr...

AI Technical Summary

Problems solved by technology

But limited to the need for a certain proportion of floating bodies to provide buoyancy, the base coverage of ecological floating islands with wet plants is insufficient, and the floating islands cannot be fully covered and hidden

Moreover, the form and shape of floating islands are relatively single, and the landscape homogeneity is serious

These all lead to the implementation effect of the ecological floating island landscape is greatly reduced

[0004] At the same time, the material of ecological floating islands is usually smooth, and the roots of wet plants provide limited attachment area, making it difficult for microorganisms to grow in the water, which makes the structure and quantity of microbial communities unable to meet the function of water purification

It also cannot provide good and sufficient wetland habitats in the water-land ecotone, which makes the ecological floating islands unable to provide high-quality wetland habitats for the transition between water and land, and improve the ecosystem service functions such as the community structure of the water ecosystem.

[0005] Furthermore, the existing ecological floating islands have poor stability, are easy to be damaged and weathered, and their service life is often limited, and the waste generated is often not recyclable and will cause secondary pollution. Therefore, we propose a method for surface water ecology Fixed floating wetland build system
