Wind and light coupled oxygen-enriched nanometer matrix composite ecological floating bed

Abstract

The invention relates to a wind and light coupled oxygen-enriched nanometer matrix composite ecological floating bed. The wind and light coupled oxygen-enriched nanometer matrix composite ecological floating bed comprises a wind-powered mechanical aeration unit that consists of a wind wheel, a protective cover, a crankshaft flywheel group, a rudder, a connecting rod, a piston, an aeration cylinder, a one way valve, a base, a flow divider valve, an aeration pipe group and a micro-pore aeration head. The composite ecological floating bed is characterized in that the wind-powered mechanical aeration unit is orderly connected with a plant-nanometer matrix photo-catalyzation and adsorption treatment unit and a biological membrane-photo-compensation unit from top to bottom, wherein the plant-nanometer matrix photo-catalyzation and adsorption treatment unit consists of a nanometer material load sheet, matrix filler, a hollow basket, a submerged plant of an aquatic plant, an emergent plant of the aquatic plant and a frame, and the biological membrane-photo-compensation unit consists of photoinduced energy-storing noctilucent powder and a microorganism biofilm culturing net. The wind and light coupled oxygen-enriched nanometer matrix composite ecological floating bed disclosed by the invention not only has the advantage of effectively removing organic pollutants and nutrient salts from a slow-flow water body but also has the advantages of being good-looking in appearance, simple in structure, economical and practical, so the wind and light coupled oxygen-enriched nanometer matrix composite ecological floating bed is suitable for treatment and recovery of common urban water bodies of polluted rivers and lakes of cities.

Description

technical field [0001] The invention belongs to the technical field of natural clean energy, in particular to an oxygen-rich nano-matrix composite ecological floating bed coupled with wind and light. Background technique [0002] In recent years, some rivers and lakes have experienced ecosystem degradation due to pollution, and some cities have become increasingly eutrophic and even black and smelly due to water bodies, which have seriously affected the urban landscape and the living security of residents. On the one hand, due to the disorderly discharge of industrial wastewater and domestic sewage, heavy metals, organic pollutants, N, P and other nutrients in rivers and lakes are enriched, and the water quality is seriously deteriorated; on the other hand, many rivers are "hardened" Or "channelization", which artificially destroys the healthy biological chain of natural rivers, reducing or even losing the self-purification ability of rivers. Existing studies have shown tha...

Problems solved by technology

Chinese patent application 200910026735 proposed a "combined ecological floating bed for water purification", and Chinese patent application 201010285641 proposed a "matrix-plant coupled dynamic water floating bed". These schemes belong to the combination of aquatic plants and matrix fillers. The treatment effect of the river sewage method is much better than that of ordinary plant floating beds, but it fails to solve the problem of low dissolved oxygen content in the water body, which leads to insufficient oxygen supply and slow degradation rate for microorganisms on the filler, and the effect is still not good; Chinese patent Application 200820156779.6 proposed a "wind-driven underwater
