Abstract

The invention discloses an artificial wetland restoration method for non-point source polluted water treatment. The method comprises the following steps that an artificial wetland restoration system is built at the non-point source polluted position, the artificial wetland restoration system sequentially comprises an ecological riverway, an artificial wetland and an ecological pool from left to right, the ecological riverway is formed by engineering transformation at the non-point source pollution position according to local conditions, a non-point source pollution water is converged into thehead end of the ecological riverway, the riverway width of the ecological riverway is 5-15 m, the section of the ecological riverway is trapezoidal, reeds are planted on the two banks of the ecological riverway and used for reinforcing revetments of the ecological riverway, and stones are arranged in the ecological riverway. The constructed wetland remediation method for non-point source pollutedwater treatment is simple, the constructed wetland remediation system is built at the non-point source polluted position to purify water, the construction cost is low, energy consumption is not needed, the operation cost is low, the method is environmentally friendly, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of ecosystem restoration, and in particular relates to an artificial wetland restoration method for non-point source polluted water treatment. Background technique [0002] As the cradle of human civilization, water resources are the material basis of people's life and production. People have lived by water since ancient times and created a splendid civilization. With the continuous advancement of urbanization and the rapid growth of population, the negative impact on water resources has also become more prominent, such as non-point source pollution. [0003] Non-point source pollution is also called non-point source pollution. Dissolved and solid pollutants from non-point source pollution flow into receiving water bodies (including rivers and lakes) through runoff under the action of precipitation (or snowmelt) from unspecified locations , reservoirs and bays, etc.) and cause eutrophication or other forms ...
