An Ecological Restoration System for Hard Channels

Abstract

The invention discloses an ecological restoration system for a hard river channel. The ecological restoration system comprises a river bottom restoration matrix, functional ecological bags and a reinforcing protection system which are arranged in the river channel, wherein the river bottom restoration matrix is laid on a river bottom layer, the functional ecological bags are laid on a fixing net of the river bottom base layer, the functional ecological bags comprise green porous biological coupling filler bags, PFU matrix micro-organism inhabiting bags and planting bags which are sequentiallylaid from bottom to top, the reinforcing protection system comprises anchor rods and a protective reinforcing net, the anchor rods are inserted into a riverbed, the protective reinforcing net covers the functional ecological bags, and the protective reinforcing net is fixedly connected with the anchor rods inserted into the riverbed through connecting ropes. According to the ecological restorationsystem for the hard river channel, ecological guarantee measures such as habitat transformation and remodeling are adopted, so that the ecological environment beneficial to growth and reproduction ofmicroorganisms is created, multiple aquatic plants and species such as snails and shellfishes are introduced into the system, and pollutant degradation and river water purification are achieved in the operation process of the whole ecological system.

Description

technical field [0001] The invention relates to a river course ecological restoration system and a treatment method thereof, in particular to an ecological restoration system for hard river courses and a treatment method thereof, and belongs to the technical field of environmental protection. Background technique [0002] In view of the characteristics of hardened water conveyance channels, such as the loss of ecological attributes, heavy organic pollution, poor fluidity and flood discharge requirements, with the goal of achieving continuous and stable improvement of water quality in stagnant channels and the reconstruction of water ecosystems, On the basis of source control and pollution interception in the early stage, ecological protection measures such as habitat transformation and remodeling were adopted to create an ecological environment conducive to the growth and reproduction of microorganisms, and a variety of aquatic plants, snails, shellfish and other species were...

AI Technical Summary

Problems solved by technology

[0003] For the hardened water delivery channel, there are hard stone revetments on both sides, and the overall terrain of the river channel is low and flat. Due to the influence of drainage pumping stations and gates in the peripheral water system, the overall fluidity is poor

During the flood discharge period in the rainy season, the flow rate is very fast, and the conventional ecological system at the bottom of the river cannot meet the demand, and it is easily washed away, resulting in the destruction of the ecological restoration system of the river channel, which cannot meet the long-term improvement of the water ecosystem of the river channel; very During the rainy season, the replenishment of water resources is less, the exchange volume of water bodies is smaller, and pollutants are enriched and released
