Abstract

The invention discloses a method for purifying river water, and relates to the field of river treatment. The method for purifying the river water quality comprises the following steps: performing aquatic plant investigation on a non-polluted area of a target river, and screening out aquatic plant dominant species of the non-polluted area; performing water quality detection on the polluted area ofthe target river, and determining the types and the standard exceeding grades of standard-exceeding pollutants in a polluted area based on a water quality detection result; and determining the standard-exceeding pollutants according to the types and the standard-exceeding grades of the standard-exceeding pollutants in the polluted area; determining target aquatic plants and the planting area and the planting density of each target aquatic plant, planting the aquatic plant dominant species in the polluted area, and planting the target aquatic plants in the polluted area according to the determined target aquatic plants and the planting area and the planting density of the target aquatic plants. The method is beneficial to sustainable development of the river water quality environment.

Description

technical field [0001] The application relates to the field of river management, in particular to a method for purifying river water. Background technique [0002] With the progress of society and the development of industrialization, the scale of cities continues to expand, a large number of rivers are occupied, the biodiversity of rivers decreases, human activities destroy the original ecological environment of rivers, and the self-purification ability of water bodies decreases. Sewage is discharged into rivers without effective treatment, making river water eutrophic. [0003] In the prior art, physical or chemical methods are usually used to improve the water quality of the river, or to change the water to improve the water quality. However, in today's scarcity of water resources, the above methods can only temporarily alleviate the deterioration of the water quality, which is not conducive to the sustainability of the river water environment. develop.
