Combined repairing technology system for various combined technologies of regenerated water landscape riverway water body

Abstract

The invention relates to a combined repairing technology system for various combined technologies of a regenerated water landscape riverway water body. The technology adopts the combined system which carries out optional regrouping on various ecological repair technologies of ecological embankment management, aeration reoxygenation, wetland water treatment, plant repair and aquatic animal repair. The content of CODcr (chemical oxygen demand), BOD5 (biochemical oxygen demand), N and P in the riverway water body repaired by the system is greatly lowered. Embankment grassing brick type ecological embankment is adopted. A plurality of plugflow aeration devices are adopted to re-oxygenate a water body on a bottom layer; an artificial wetland is planted with three plants of reed, calamus and canna; a plant community with better salt tolerance is adopted for phytoremediation; each plant community is configured with emergent aquatic plants, floating plants and submerged plants; parts of stream segments are configured with a small quantity of floating plants; and suspended matters in the water body can be effectively reduced by aquatic animal repair to remove green algae substances in the water body and increase water body transparency.

Description

technical field [0001] The invention relates to a joint restoration process of multiple combined technologies of reclaimed water landscape river water bodies, specifically, a reasonable combination of various ecological restoration technologies such as ecological revetment, aeration and re-oxygenation, wetland water treatment, plant restoration, and aquatic animal restoration. Combined to form a joint restoration process for landscape river water bodies. This restoration process can effectively improve the water quality of the river and realize the long-term purification and maintenance of the river water. Background technique [0002] Since the 1970s, there have been energy crises, ecological crises, and environmental crises worldwide. In particular, the increasingly severe crisis of water resources has made water resources, which are the source of life, become a major social issue involving economic development, political relations, and human health. With the acceleratio...

Problems solved by technology

However, the application of reclaimed water to landscape water technology improves the urban living environment and people's quality of life, but there are also some immature technical problems

Most of the urban landscape water bodies are discontinuously flowing water bodies with slow flow velocity and weak self-sustaining ability of aquatic ecosystems. In addition, the background value of recycled water pollutants is relatively high, which makes the water quality of recycled water landscape water bodies not optimistic.

At present, some breakthroughs have been made in the construction of urban river landscapes in my country, but some of them are only for flood control and trade purposes, one-sidedly emphasize the functions of water conservancy and ignore the ecological landscape effects of rivers, and adopt hard slope protection, straight and upright when the bend is removed Artificial means such as anti-wave walls, which not only break the natural features of the river, but also cause adverse effects on the natural environment
