Ecological restoration method and device for eutrophicated riverway water

Abstract

The invention discloses an ecological restoration method and device for eutrophicated riverway water. The device comprises a plurality of integrated multilayer ecological areas arranged in a riverway;any one integrated multilayer ecological area is used for coordinating the restoration capability of the integrated multilayer ecological area and the restoration capability of the adjacent integrated multilayer ecological area by controlling the flow velocity of water flow in the area so as to carry out cooperative restoration on the riverway; and the integrated multilayer ecological area comprises a transparent framework, a flexible balance weight part used for being attached to the bottom of a riverway is installed at the bottom end of the transparent framework, and an algae discarding layer, a plankton control layer and a plant planting layer are arranged on the transparent framework from top to bottom. The riverway is monitored and the pollution source is positioned through the restoration area, and the self-cleaning capacity of the area is improved through multilayer treatment schemes and microcirculation formed among the multiple treatment schemes in the restoration area.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an ecological restoration method and device for eutrophic river water bodies. Background technique [0002] All waters have a certain degree of self-purification ability. This self-purification ability comes from the dissolved oxygen in the water. If the water lacks oxygen, the waters must be seriously polluted. When a small amount of pollutants enter the waters, the dissolved oxygen in the waters will oxidize and decompose the pollutants into non-polluting inorganic substances and release them in the form of gas. The waters will be clean, and after a period of natural dissolution, the waters will recover and dissolve Oxygen content, so as to realize the circulation balance of the self-purification ability of the water area, and maintain the clean ecological environment of the water area. However, in recent years, with the rapid economic development and rapid popu...
