Embodiment 1

[0026] Embodiment 1, a method for preventing and controlling cyanobacteria, adopts the method of artificial rainmaking on the water body, reduces the water temperature of the surface layer of the water body; described artificial rainmaking is to spray the water body and / or bottom mud in the middle and lower part of the water body or the bottom after being absorbed. the surface of a body of water.

Embodiment 2

[0027] Embodiment 2, in the control method of blue-green algae described in embodiment 1: described artificial rainmaking method is: adopt mobile or fixed fire-fighting boat, sprinkler or surface aerator to carry out artificial rainmaking on water body .

Embodiment 3

[0028] Embodiment 3, in the control method of cyanobacteria described in embodiment 1 or 2: when the maximum temperature of the day reaches above 32°C, artificial rainmaking is adopted on the water body.

Abstract

The invention provides a control method for blue algae. According to the method, rainmaking above a water body is employed to reduce surface temperature of the water body; rainmaking is realized by sucking up water at middle and lower parts or at bottom of the water body and / or sediment and spraying the water and / or sediment onto the surface of the water body. A movable or fixed fire boat, a water sprayer or a surface aeration machine can be used for rainmaking above the water body. Suction of water at middle and lower layers and / or sediment and spreading of the water and / or sediment onto the surface of the water body artificially lead to turbidity of the water body; production capacity of algae is extremely limited when the water body is turbid, thereby achieving the purpose of controlling hypertrophy of algae. Through adsorption capability of the sediment of the water body, alga cells in the water body are adsorbed and settle to the bottom of the water body, and therefore, concentration of algae in the water body is greatly reduced in a short time, thereby suppressing the tendency of outbreaks of algae and reducing surface temperature of the water body. The control method provided by the invention has the advantages of a simple design, convenient operation, low cost and easy popularization and is applicable in a water area with a large area.

Description

technical field [0001] The invention relates to a control method for algae, in particular to a control method for cyanobacteria. Background technique [0002] The environmental problems caused by the cyanobacteria outbreaks caused by the eutrophication of water bodies have attracted more and more attention from the society, but the effect of many efforts is limited. The problem of cyanobacteria control is still serious. [0003] Like all plants, the growth of algae also requires suitable external objective conditions. Specifically for algae, the objective factors that restrict the growth of algae in water bodies are light, nutrient nitrogen, phosphorus, temperature, and oxygen content in water bodies. [0004] Throughout the domestic and foreign measures to control cyanobacteria outbreaks, there are mainly the following types, and now we will introduce and evaluate their deficiencies or mistakes one by one: [0005] 1. Biological Control Law. Cyanobacteria are the food of...
