A method for rapid flocculation and removal of cyanobacteria in water

Abstract

The inventions relates to a method for quickly flocculating and removing blue-green algae in a water body. After being diluted to be at the concentration of 20-100 ppm, high-iodine strontium aluminate is evenly sprinkled on the surface of the water body, and polymeric aluminum with the concentration being 20-50 ppm is evenly sprinkled on the surface of the water body 20-60 minutes later after the high-iodine strontium aluminate is used; after the blue-green algae in the water body is flocculated to form pieces, the blue-green algae are fished mechanically or manually. Thus, the water body is prevented from being polluted, and the glue-green algae can be flocculated to be fished conveniently.

Description

technical field

[0001] The invention relates to the field of water pollution control, in particular to a method for rapidly flocculating and removing blue-green algae in water bodies. Background technique

[0002] At present, the pollution of many lakes has caused the phenomenon of cyanobacteria blooms to be very serious. The methods for removing cyanobacteria blooms in the prior art generally include mechanical salvage methods or chemical agent killing methods. The pure mechanical salvage method requires a lot of manpower and material resources, and the cyanobacteria are scattered and difficult to salvage; Copper sulfate is often used in the chemical killing method, which will cause damage to other organisms in the lake, or cause secondary pollution after enrichment. Contents of the invention

[0003] In order to solve the above technical problems, the present invention provides a method for quickly flocculating and removing cyanobacteria in water bodies, which avoids pol...
