Multi-stage water power aerobic ecological wetland type slope protection device

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 ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem of low dissolved oxygen in ordinary ecological slope protection, apply potential energy oxygenation technology to the construction of ecological slope protection, and develop a kind of river and lake ecological wetland slope protection technology with good reoxygenation effect. To a certain extent, the problem of wetland sedimentation and saturation can be alleviated
