Ecological environment reconstruction system for riverway

Abstract

The invention discloses an ecological environment reconstruction system for a riverway. The ecological environment reconstruction system comprises a sedimentation tank, a filter tank and a clear waterriverway which are disposed on the riverway, wherein a sand trap is arranged between the sedimentation tank and the filter tank; a water passing dam is arranged between the filter tank and the clearwater riverway; the filter tank comprises a riprap layer disposed on the surface of the river bottom; an anti-seepage geotextile and plain soil layer, a gravel layer, a grass brick layer, a planting soil layer and an aquatic plant layer are sequentially arranged on the riprap layer from bottom to top; and a clear water collecting device is communicated to the clear water riverway through a water conveying pipe. The river ecological environment reconstruction system can improve the problem of low water self-cleaning capacity caused by severe damage to the ecological environment of the riverway,replacement of polluted water with clean water, treatment with a digging and dredging mode, consumption of a large amount of human and material resources and destroying of a physical structure of theriverway.

Description

technical field [0001] The invention belongs to the technical field of river channel environment improvement, in particular to a river channel ecological environment improvement system. Background technique [0002] As the country strengthens the governance of the ecological environment, the concept of building beautiful mountains and rivers and creating a beautiful homeland is deeply rooted in the hearts of the people. However, with the rapid development of the economy, a large amount of industrial wastewater and domestic sewage are discharged into surface water bodies such as rivers and lakes, and these wastewaters carry a large amount of nutrients. Due to the discharge of nitrogen, phosphorus and other elements, and the lack of necessary circulation in the water body, the algae and other plankton will multiply rapidly, the dissolved oxygen in the water body will decrease, the water quality will deteriorate, and fish and other organisms will die in large numbers, resulting...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in view of the serious damage to the ecological environment of the above-mentioned river course, the use of clean water to replace the polluted water body and dredging and dredging for treatment will consume a lot of manpower and material resources, and will also destroy the physical structure of the river course, resulting in the self-purification ability of the water Poor problem, the present invention provides a river ecological environment improvement system
