Method for inhibiting growth of algae through allelopathy of aquatic plants

Abstract

The invention discloses a method for inhibiting the growth of algae through allelopathy of aquatic plants. In the method, a certain amount of hydrodictyon is put into an algae-containing eutrophic water body, the hydrodictyon releases allelochemicals under the induction of the algae, and the allelochemicals can effectively inhibit the growth of the algae; in addition, the hydrodictyon has high capability of removing nitrogen and phosphorus, so that the eutrophication degree of the water body can be essentially reduced, water bloom or red tide is prevented and controlled, a water source is cleaned, and the aquaculture industry, tourism ecological environment, the drinking water of urban residents, and agricultural and industrial water in various areas easily suffering from algae solution are protected.

Description

technical field

[0001] The invention relates to a method for removing algae, which belongs to the technical field of environmental engineering, in particular to a method for inhibiting the growth of algal blooms by utilizing the allelopathy of aquatic plants. Background technique

[0002] At present, the removal methods of algae in eutrophic water body mainly include physical method, chemical method and biological method.

[0003] 1. Physical method

[0004] Physical methods mainly include mechanical or manual salvage, clay flocculation and shading techniques. The physical method directly removes the algae in the water body without secondary pollution, but requires expensive expenses, so this method can only be limited to small water bodies or local water areas of large water bodies.

[0005] 1. Mechanical algae removal method In the initial stage of large-scale algae removal operations or the preparation stage before algae removal, it is necessary to properly remove algae...
