An ecological hard revetment suitable for variable water level

Abstract

The invention discloses an ecotype hard embankment applicable to a variable water level. Embankments are symmetrically positioned on the two sides of a river channel; each embankment has certain gradient, and comprises a slope body and a vegetation planting area planted on a slope surface; the vegetation planting area comprises a first vegetation planting area and a second vegetation planting area in sequence along the dip direction of the slope body; a water quality purification area is formed below the first vegetation planting area; the water quality purification area comprises a gravel layer, a coconut shell activated carbon layer and an ammonia absorbing stone layer in sequence along the dip direction of the slope body; an oxygenated area and an anaerobic area are arranged in sequence in a cavity below the second vegetation planting area; the cavity is provided with a plurality of channels communicated with a river; an impeller is further arranged in the cavity; the impeller is drive through energy collected by a solar panel arranged on the slope surface. The ecotype embankment structure can further purification treatment on river water through the variable water level, meanwhile can eliminate negative effect on the embankment structure by the variable water level, and effectively intensifies the purification capacity of the embankment on initial rainwater on a unit area.

Description

technical field [0001] The invention relates to an ecological hard revetment suitable for variable water levels, and belongs to the technical field of rain and sewage diversion. Background technique [0002] At present, the pollution of water resources is becoming more and more serious, and there are more and more treatment facilities and requirements for river sewage purification and rainwater collection. Since variable water level rivers (such as gated rivers, tidal rivers, etc.) will have river pollution and non-point source pollution caused by rainfall runoff, it is necessary to set up river revetments on both sides of the river. However, the existing variable water level ecological revetment has the problems of large land occupation, poor stability, and the death of water purification plants when the water level changes. The development of ecological revetment with more efficient and low energy consumption water purification capacity is necessary. Contents of the inv...
