The invention discloses a river channel multi-level intelligent ecological
revetment system based on a
sponge city. The
system comprises a river channel, an ecological slope protection and a river
bank, wherein a step type stone cage is arranged between the ecological slope protection and the river
bank; trees and shrubs are planted on the river
bank, the ecological slope protection comprises a clay layer, a
denitrification layer, an adsorption layer, a filtering layer and a soil layer, wherein herbaceous plants are planted on the soil layer, and a water distribution pipeline is arranged at the top end of the ecological slope protection; an
inductor control cabinet is arranged at the upper end of the step type stone cage, a
water level sensor is arranged at the front end of the step type stone cage, the
water level sensor is provided with a DO monitoring probe, and an
aeration pump and a
sewage pump are arranged in the river channel; and the
water level sensor, the DO monitoring probe,the
aeration pump and the
sewage pump are connected to the
inductor control cabinet, and the
sewage pump and the water distribution pipeline are connected through a water collecting pipeline. According to the
system, the effects of "water absorption,
water storage,
water seepage and water purification" during rainfall are fully realized, the problem that the purification effect in rainfall or
river flood season of an ordinary ecological
revetment is limited is solved, and the problem of poor
water quality of the river channel in
dry season is solved.
