Method for controlling hypertrophy of green algae

Abstract

The invention is applicable to the technical field of water environments, and provides a method for controlling hypertrophy of green algae. The method comprises the following steps: 1, primarily treating the green algae: throwing plant ash and a flocculant into water, arranging a micro-bubble generating device in the water, and mechanically removing aquatic floats on the surface of the water 3-5 days after the throwing of the plant ash; 2, finely treating the green algae: adding a chemical algaecide to the primarily treated water; 3, carrying out organic matter treatment: adding a coagulant tothe finely treated water, and adding blue vitriol to the water; and 4, planting floating plants: planting the floating plants on the surface of the water subjected to the organic matter treatment. The method can comprehensively and thoroughly control the green algae in the water, has few damages to the water, and achieves the overall improvement of the quality of the water.

Description

technical field [0001] The invention relates to the technical field of water body environment treatment, in particular to a method for controlling overgrowth of green algae. Background technique [0002] Due to excessive nitrogen, phosphorus and other nutrient elements, a large number of algae blooms in surface waters, often forming a thick floating layer of algae on the water surface, which greatly deteriorates the water environment, and also leads to fishy water and a large number of deaths of aquatic animals. [0003] Chlorella is a common aquatic algae, its excessive reproduction will make it difficult for sunlight to penetrate the water layer, affect the photosynthesis of plants in the water, and may also cause the supersaturation of dissolved oxygen in the upper layer of the water area and the lack of dissolved oxygen in the bottom layer, affecting aquatic animals Normal growth and reproduction. In addition, algae will release algal toxins during metabolism or after al...

[0002] Due to excessive nitrogen, phosphorus and other nutrient elements, a large number of algae blooms in surface waters, often forming a thick floating layer of algae on the water surface, which greatly deteriorates the water environment, and also leads to fishy water and a large number of deaths of aquatic animals.

[0003] Chlorella is a common aquatic algae, its excessive reproduction will make it difficult for sunlight to penetrate the water layer, affect the photosynthesis of plants in the water, and may also cause the supersaturation of dissolved oxygen in the upper layer of the water area and the lack of dissolved oxygen in the bottom layer, affecting aquatic animals Normal growth and reproduction. In addition, algae will release algal toxins during metabolism or after algae rupture, such as Anabaena, A. aeruginosa, and Microcystis aeruginosa. These algae toxins are directly toxic to fish, humans and animals.

[0004] Although many people use aquatic plant methods to control the overgrowth of green algae caused by eutrophication of water bodies, the effect is not great

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
