Urban riverway ecological restoration system and method

Abstract

The invention relates to an urban riverway ecological restoration system. The system comprises a drop dam arranged on the slope of a riverway, artificial aquatic plants which are positioned under the drop dam and laid along the slope of the riverway, a water pump which is arranged at the bottom of the riverway and is used for pumping water to the drop dam, and a water delivery pipe which is connected with the water pump and the drop dam and used for delivering water pumped from the water pump to the drop dam, wherein water overflows from the drop dam and flows down along the surface of the artificial aquatic plants. The dissolved oxygen of a water body is increased by utilizing the principle of drop aeration, and a living environment for aquatic plants is creased; and the landscape effect of the riverway is increased, so that the riverway is beautiful; the artificial aquatic plants can be used for manyfold adsorbing microbes in the water after being arranged in the water, pollutants in the water can be effectively decomposed by the micropopulation, and construction of an aquatic plant living environment is promoted. The urban riverway ecological restoration system is suitable for a river bank hardened riverway, is simple, and has the advantages of low cost and good effect; and the aquatic plants are arranged under the drop dam and extends to the river bottom constantly, so that water can flow down along the aquatic plants, and the aquatic plants can be prevented from exposed in the sun in summer.

Description

Technical field [0001] The invention relates to the field of urban river restoration, in particular to an urban river ecological restoration system and method. Background technique [0002] The inventor discovered a common problem in urban rivers: hardened rivers destroy the ecological environment of the river ecosystem. For a long time in the renovation of small and medium-sized rivers in cities in my country, the river slope protection mainly uses mortar or dry masonry, cast-in-place concrete and other materials, while the bank protection works mostly use vertical concrete retaining walls. As a result, these structural forms are cut off from the ecological point of view. The water-land transition zone of rivers has caused environmental degradation of water bodies and land to varying degrees. The two banks of the river are made of hard concrete blocks, and some of them are smooth on three sides. The bottom of the river is also made of cement, which further reduces the living env...
