Constructed wetland island water quality purification system and construction method thereof

Abstract

The invention discloses a constructed wetland island water quality purification system and a construction method thereof. The water quality purification system of the constructed wetland island comprises an island body, an ecological gabion and an aquatic plant, the ecological gabion is arranged at the joint of the island body and the water body, the ecological gabion comprises a gabion net frame,a gabion top net groove and a gabion side net groove, the gabion net frame is L-shaped, its bottom is inserted in the body of the island, the top mesh groove of the gabion is arranged on the top of the gabion net frame, the side net groove of the gabion is arranged on the side of the gabion mesh frame far away from the island body, volcanic rock stones are loaded in the inside of the gabion meshframe, the top net groove of the gabion and the side net groove of the gabion are provided with ecological fiber bags. The ecological gabion adopted by the constructed wetland island is provided withplanting grooves at the side and top, which not only can enrich the landscape level of the water body and create beautiful artistic conception, but also has the functions of self-purification and hydrophilicity, thus achieving the effect of purifying water.

Description

technical field [0001] The invention belongs to the technical field of water quality treatment and ecological landscape, and in particular relates to a water quality purification system of an artificial wetland island and a construction method thereof. Background technique [0002] An island refers to an area surrounded by water in rivers and lakes. Most of the current islands are naturally formed, and the main component is natural clay minerals. When the water volume is large, it is easy to be washed away, resulting in the disappearance of the natural island. Wetland islands have ecological benefits such as regulating water sources, regulating climate, purifying water quality, and protecting species. At the same time, they play an important role in improving the ecological landscape effect of the entire lake, and are an important part of ecological rainwater purification in the park. During the construction of constructed wetland islands, stone masonry is mostly used to mai...

AI Technical Summary

Problems solved by technology

During the construction of artificial wetland islands, stone masonry is mostly used to maintain the surroundings of the island body. Stone masonry has poor slope consolidation effect, and it is easy to block the material exchange between the island body and the water body, which is not conducive to the purification of water quality.

In order to solve the above problems, the periphery of some wetland islands is maintained with ecological gabions, which greatly improves the material exchange rate between the island body and the water body, but the part of the gabion in contact with the water body lacks soil matrix and cannot grow aquatic plants. On the one hand, it reduces the purification effect of aquatic plants on water bodies; on the other hand, it affects the landscape and ornamental properties of wetland islands
