River channel ecological slope purification system

Abstract

The invention provides a river channel ecological slope purification system. The system comprises a protection belt, aquatic plant and a water circulating device, wherein the protection belt comprisesa plurality of pile bodies; the pile bodies are inserted into a soil layer at the outer side of the slope of the river channel, and planting soil is filled between the protection belt and the slope of the river channel; the aquatic plant is arranged on the planting soil which is filled between the pile bodies and the river channel slope; and the water circulating device comprises a submersible pump, a circulating pipeline and a plurality of water outlet pipes, wherein the submersible pump is arranged in a river channel water area, the circulating pipeline is embedded in the planting soil, andthe plurality of water outlet pipes are connected to the circulating pipeline correspondingly. According to the river channel ecological slope purification system, the surface source pollution can beeffectively reduced, the rainwater can be retained and purified in rainy days, and the river channel water area can be purified through the water circulation under the non-rainwater weather.

Description

Technical field [0001] The invention relates to the technical field of comprehensive treatment of urban water environment, in particular to a river ecological side slope purification system. Background technique [0002] As the transition zone between the water body of the river course and the land along the river course, the river slope plays the role of material, energy and information exchange between the water and land ecosystems, and also plays the role of river slope protection, ecological corridor and buffer zone. [0003] In the early technology, due to the lack of technology and the lack of understanding, the early river slope water environment management usually adopted a single-structured flood prevention and anti-flood project. This kind of flood control and anti-flood project only has the ability to protect the river slope from the flow of water. The basic functions of erosion and erosion, flood prevention and flood resistance, mostly use impervious cast-in-place concr...

AI Technical Summary

Problems solved by technology

[0003] In the earlier technology, due to the lack of technology and lack of understanding, the early river slope water environment treatment usually adopts a single-structure flood control and flood control conservancy project, which only has the ability to protect the river slope from water flow. For basic functions such as erosion and flood control, most of the hard materials such as impermeable cast-in-place concrete and mortared stones are used to construct the river slope. However, on the one hand, urban development and construction have increasingly strict restrictions on land use on both sides of the river. The land occupation requirements for river slope construction are less and less, and at the same time, higher durability and shorter construction period are required for slope construction; Good riparian water bioremediation and buffer retention

[0004] In the long-term practice, with the innovation of technology, a kind of upright hard revetment structure is proposed in the prior art for the technical problems existing in the earlier technology, which is a kind of restoration on the basis of the original river slope revetment, mainly The river bank is transformed through vegetation restoration and transformation, substrate laying and composite transformation technology, but this single-purpose transformation method is not enough for the ecological composite transformation of the river bank
