River channel ecosystem with functions of sewage interception, slope protection and water purification based on silt resource utilization and construction method thereof

Abstract

The invention discloses a river channel ecosystem with functions of sewage interception, slope protection and water purification based on silt resource utilization and a construction method thereof. The ecosystem sequentially comprises a roadside sewage interception system which exposes the surface of a water body, an ecological slope protection system in the middle portion and a river channel water purification system in the water body which are arranged from an embankment on the one side of the river channel to the water body, wherein the roadside sewage interception system is composed and constructed by the splicing of bricks with the functions of sewage interception and water permeability, the ecological slope protection system comprises a silt soil protection slope and a vegetation concrete protection slope, and the river channel water purification system is composed of unit water purification system cages. Through the technology of the silt resource utilization and in cooperationwith three properties of the sewage interception, the slope protection and the water purification, and the constructed river is integrated in ecology, good in effect and strong in environmental effect.

Description

technical field [0001] The invention belongs to the technical field of river ecological restoration, and in particular relates to a river ecological system of sewage interception-slope protection-water purification based on silt resource utilization and a construction method thereof. Background technique [0002] In recent years, due to the annual increase of human domestic waste and the impact of agricultural non-point source pollution, the self-purification ability of rivers has been lost, water quality has deteriorated, water bodies have become eutrophic, and the dredging of river sediments has also brought energy and manpower waste. How to properly deal with the resource of silt is a research hotspot. [0003] With the development of society and economy, people are gradually paying attention to the regulation of river channels. It is a trend to systematically study and restore rivers from the perspective of ecological environment protection system. However, the traditio...

AI Technical Summary

Problems solved by technology

However, the traditional river slope protection technology mainly adopts mortar rubble slope protection and hole type slope protection, which isolate the original ecological environment, deviate from the natural law of ecology, and are not conducive to the ecological restoration of the river.
