The invention provides a multi-stage water power aerobic ecological
wetland type slope protection device, which comprises an ecological
wetland bed, a water inlet groove and a water outlet groove. One end of the ecological
wetland bed is connected with the bottom of the water inlet groove through a limber hole, while the other end is connected with the water outlet groove which is provided with an aerobic
pipe; the water outlet groove is divided into an upper water groove and a lower water groove through a baffle plate; two ends of the aerobic
pipe are respectively arranged in the upper water groove and the lower water groove; the lower water groove is connected with the next stage of water inlet groove through the limber hole; and the lower water groove of the lowest stage of water outlet groove is provided with a
water discharge port. The device can be applied to the slope protection construction of a river and a lake, intercepts and purifies the area surface
pollution discharged into the river and the lake, and also can convey water in the river and the lake to a high position by using a water pump; and the water flows from the first stage of the water power aerobic ecological wetland to the next stage gradually and is subjected to multi-stage
processing of the wetland, so that the
water quality in the river and the lake is purified, the effects of improving dissolved
oxygen and denitrifying are good, and the wetland
silt saturation can be relieved to a certain extent.
