Embodiment 1

[0012] Control attached figure 1 The multi-stage hydraulic aerobic ecological wetland type slope protection device includes an ecological wetland bed 1, a water inlet tank 2 and a water outlet tank 3. The ecological wetland bed 1 is filled with upper and lower layers of fillers, and the upper layer of soil substrate 6 is used as a growth substrate for plants 10, on which Plant 10, the lower layer is a purification filler 7 with better permeability, such as zeolite, gravel, pebble, ceramsite and yellow sand, and each purification filler 7 is paved layer by layer in order of decreasing particle size from bottom to top, and the surface of purification filler 7 is Form biofilm, with microorganisms and rotifers,

[0013] The height of each level of ecological wetland bed 1 is 40-50cm, and the length is 1-1.5m; the multi-level hydraulic aerobic ecological wetland type slope protection device is 3 to 5 levels, and the outlet of the lowest level of water tank must not be used in pract...

Abstract

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.

Description

technical field [0001] The invention relates to an artificial wetland ecological slope protection structure, which is applied to river and lake water quality purification and non-point source pollution interception projects, and belongs to the technical field of river and lake ecological engineering. Background technique [0002] At present, the slope protection forms of rivers and lakes mainly include natural slope protection, hard slope protection and ecological slope protection. Due to the limited removal effect of the first two types of pollutants entering the river in the form of non-point sources, ecological slope protection has become a research hotspot in recent years and has gradually been popularized and used. Ecological slope protection is to adsorb, absorb, decompose and intercept pollutants in water under the combined action of plants, filler media and microorganisms. Its advantages are good treatment effect, strong impact resistance, and strong N and P removal ...
