Ecological restoration system with coupling aeration of stepping stone on water surface and overflow weir

Abstract

The invention provides an ecological restoration system with coupling aeration of stepping stone on a water surface and an overflow weir. The system includes stepping aeration units, overflow aerationunits, a protective unit and an ecological landscape unit. Each stepping aeration unit is composed of the stepping stone on the water surface, a one-way valve, a sealing ring, an automatic resettingspring, a base, vent holes and a cavity shell; each overflow aeration unit is composed of a housing, a baffle and fillers; the protective unit consists of suspension cables, suspension rods and bridgepiers; the ecological landscape unit consists of floating-leaved plants and emergent aquatic plants. Pedestrians step on the stepping stone on the water surface to conduct stepping aeration, water isdrained through the overflow weir for aeration, and by combining the two aeration modes, dissolved oxygen in water can be effectively increased; assimilative absorption of heavy metal and organic pollutants in the water is achieved through the floating-leaved plants and the emergent aquatic plants. The system has the advantages of being attractive in appearance, simple in structure, low in expense, free of secondary pollution and the like.

Description

technical field [0001] The invention belongs to the field of river water pollution control, and in particular relates to an ecological restoration system for coupled aeration of steps and overflow weirs. Background technique [0002] Water is an important part of the urban ecosystem. With the continuous improvement of people's living conditions, ecological awareness has also been continuously improved. Therefore, while carrying out water pollution control, people also put forward higher requirements for water body landscape. Water pollution control methods mainly include: physical method, chemical method and biological method. Among them, the physical method mainly includes sediment dredging, water diversion and silting, and mechanical algae removal, etc. The chemical method is mainly to add various chemical reagents to the polluted water body to adjust the water environment, but these methods often treat the symptoms but not the root cause, and are prone to secondary pollut...
