Landscape lake water quality purification system

Abstract

The invention relates to a landscape lake water quality purification system, and is applied to the technical field of water environment pollution treatment. The system comprises a lake body, wherein the bottom of the lake body is provided with a first wooden pile row distributed along the length direction, the first wooden pile row is provided with a first bamboo curtain piece extending out of thewater surface, the first bamboo curtain piece divides the lake body into a first water area and a second water area, an area of the first water area is larger than an area of the second water area, aheight of the first water area is greater than a height of the second water area, a soil-filling layer is laid at the bottom of the second water area, a permeating-resistant geotextile is arranged between the soil-filling layer and the first wooden pile row, one end of the permeating-resistant geotextile extends upwards to the first bamboo curtain piece, the other end extends to the bottom of thesoil-filling layer, and the soil-filling layer, near the shore of the lake body, is planted with reeds. The system has the effect of improving the survival rate of aquatic plants.

Description

technical field [0001] The invention relates to the technical field of water environment pollution control, in particular to a landscape lake water purification system. Background technique [0002] Landscape lakes are generally artificial lakes, which are a kind of lake dug out by people in a planned and purposeful manner, and are produced in an unnatural environment. The landscape lake provides the city with a suitable landscape atmosphere and is conducive to improving the quality of the urban environment. [0003] As an open system, the landscape lake is easily polluted by the surrounding environment. At present, the pollution prevention and control method of landscape lake water body mainly adopts ecological purification technology. By planting aquatic plants, water purification system of aquatic plants is constructed to enhance the self-healing ability of water body. [0004] However, in the initial stage of planting aquatic plants (such as emergent plants such as ree...

Problems solved by technology

[0004] However, in the initial stage of planting aquatic plants (such as emergent plants such as reeds), since the roots of aquatic plants are not firmly rooted in the soil and the area of ​​the landscape lake is large, aquatic plants are easily swept away and blown when encountering large waves. down, affecting the survival rate of plants
