Abstract

The invention provides an ecological restoration method of a city riverway. Firstly, the riverway pollution condition is investigated and detected, and the pollution condition and the ecological condition in different areas of the riverway are determined; according to investigating and detecting data, segmented planning treatment is performed, ecological restoration of the riverway needs to directat clearing of sludge at the river bottom, then the root can be treated, and it is prevented that waste accumulated in the sludge at the river bottom continuously pollutes the riverway; the water flow direction and the flow speed of the riverway are improved through an overflow dam, diverse flow speed zones favorable for various organisms are formed, and planting of various aquatic plants is facilitated; contact between the organisms in the riverway and river bank soil is improved due to ecological bank protecting, and the self-cleaning capacity of water flow flowing into the riverway is improved; and an intercepting net is used for intercepting waste floating in the riverway, the waste is driven into a collecting groove due to the water flowing effect, and concentrated clearing by personnel is facilitated.

Description

technical field [0001] The invention relates to the technical field of environmental governance, in particular to an ecological restoration method for urban rivers. Background technique [0002] With the development of the economy and the advancement of urbanization, the enterprises and residents around the urban rivers are relatively dense, and domestic and construction waste gradually pollute the rivers. The long-term accumulation has led to black and smelly water bodies in urban rivers, and the ecology of the rivers has gradually been destroyed, seriously affecting For urban landscape and residents' health, it is necessary to provide an ecological restoration method for urban rivers to improve the polluted rivers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for ecological restoration of urban rivers to solve the problems raised in the above-mentioned background technology. [0004] The technical ...
