A Constructed Wetland Based on Bend Water Flow

Abstract

The invention discloses an artificial wetland based on a curved channel water flow. The artificial wetland based on the curved channel water flow comprises an arc artificial wetland body, a wetland lower-end pipe and a wetland upper-end pipe. The arc artificial wetland body is installed at a concave bank of a meandering river, and the arc artificial wetland body successively comprises a gravel layer, a coarse sand layer, a fine sand layer, a soil layer and plants planted on the soil layer from bottom to top, wherein the top height of the fine sand layer is aligned to a normal water level; oneend of the wetland lower-end pipe is communicated with the meandering river, and the other end of the wetland lower-end pipe is communicated with a wetland lower port; and one end of the wetland upper-end pipe is communicated with a wetland upper port, and the other end of the wetland upper-end pipe is provided with two bifurcated pipes which are a clear water outlet pipe and a waste water inlet pipe respectively. The artificial wetland is capable of using the vantage ground of the meandering river without applying an external force, carrying water from a river channel, and helping the river to reduce the water level of the river channel and cutting down the peak discharge in a flood season, and can be used as an ecological filtering medium for filtering and collecting river water, as wellas processing the waste water.

Description

technical field [0001] The invention relates to the technical field of artificial wetland design and ecological restoration, in particular to an artificial wetland based on curved water flow. Background technique [0002] With the development of industrialization in our country, the national economy is also developing rapidly. At the same time, our country is also facing severe challenges of water resource shortage and water environment deterioration. On the one hand, due to the insufficient attention paid to the separation of underground rainwater and sewage and the sewage treatment of enterprises in the last century, the construction of sewage drainage projects is not complete, resulting in the domestic sewage and industrial wastewater generated in cities can only be discharged into urban rivers, resulting in the deterioration of the ecological environment of river water bodies On the other hand, most cities in my country are in a monsoon climate, and the distribution of an...

Problems solved by technology

[0005] At present, there is no invention that combines peak shaving and sewage treatment during the flood season. Therefore, by using the powerful terrain of the curved water flow, a kind of water can be taken in the flood season, and the sewage can be filtered before entering the river. It can carry out two-way treatment of river water and sewage. Filtered constructed wetlands are especially important
