Description
Technical Field

Background
The blue algae is lack of competition and inhibition of other species in the ecological system, and can be rapidly propagated and grown under the conditions of proper nutrition and temperature, and large-area bloom is formed. When the cyanobacteria bloom is exposed in a large scale, a large amount of cyanobacteria are accumulated, decomposed and decomposed, and unbearable fishy smell is emitted, so that the offshore environment is seriously polluted; in addition, the cyanobacterial bloom also influences the water supply safety of drinking water source places.
Most blue algae have bubbles to float on the water surface, so that the light energy on the water surface can be effectively utilized for photosynthesis. There are various control methods for high-density blue-green algae floating on the surface of water, and the control methods can be summarized into two categories: in situ treatment and ex situ treatment. The ectopic treatment is mainly to directly collect and convey the blue algae on the water surface to a treatment place for treatment by a mechanical method. Because the concentration of the blue algae in the algae water is very low, the amount of the algae water to be treated is very large, and one of the important technical links for quickly removing the blue algae water bloom is to use a high-efficiency blue algae concentration device to reduce the volume of the algae water to be treated and reduce the concentration cost of algae slurry.
