Embodiment 1
[0020] Embodiment 1, a method for preventing and controlling water body algae pollution at the water intake of a water plant. A surface aerator is installed at the water intake of a water plant, and the surface aerator is started to spray water when necessary.
Embodiment 2
[0021] Embodiment 2, a method for preventing and controlling the algae pollution of the water body at the water intake of the water plant, setting an artificial fountain at the water intake of the water plant, and starting the artificial fountain to spray water when necessary.
Embodiment 3
[0022] Example 3, an example of preventing and controlling algae pollution in water intakes of water works. A cyanobacteria outbreak occurred in the Qutashan Reservoir in Ganyu County, Jiangsu Province. At that time, cyanobacteria covered two-thirds of the reservoir area. After organizing personnel to salvage with fishing nets, install the surface aerator according to the method of Example 1, and the surface aerator covers 3000m 2 When the water temperature of the surface 20-30cm of the water body at the water intake reaches above 25°C, start the surface aerator for water spraying treatment. As a result, the algae count dropped by more than 90%, and the water became clearer. After that, there was no blue-green algae outbreak at the water intake. From the above actual evidence, it is not difficult to draw a conclusion that the above methods and measures can be used to solve the problem of controlling cyanobacteria outbreaks, and have high feasibility.
