Problems solved by technology

[0002] At present, the pollution of many lakes has led to serious cyanobacteria blooms. 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

Embodiment 1

[0009] A kind of fast flocculation and the method that removes blue-green algae that the embodiment of the present invention provides, in 300m 2 In the experimental pool with cyanobacteria, dilute strontium periodate to a concentration of 20ppm and evenly spray it on the surface of the water body in the experimental pool. After using strontium periodate for 30 minutes, spray polyaluminum chloride with a concentration of 25ppm evenly on the surface of the water body ; After the cyanobacteria in the water body are flocculated into pieces, they are manually salvaged, and the salvaged cyanobacteria are filtered out of the water by mechanical pressure, and the water is returned to the experimental pool.

Embodiment 2

[0011] A kind of fast flocculation and the method that removes blue-green algae that the embodiment of the present invention provides, in 300m 2 In the experimental pool with cyanobacteria, dilute strontium periodate to a concentration of 30ppm and evenly spray it on the surface of the water body in the experimental pool. After using strontium periodate for 40 hours, spray polyaluminum chloride with a concentration of 30ppm evenly on the surface of the water body ; After the cyanobacteria in the water body are flocculated into pieces, they are manually salvaged, and the salvaged cyanobacteria are filtered out of the water by mechanical pressure, and the water is returned to the experimental pool.

Embodiment 3

[0013] A kind of fast flocculation and the method that removes blue-green algae that the embodiment of the present invention provides, in 300m 2 In the experimental pool with cyanobacteria, dilute strontium periodate to a concentration of 70ppm and spray evenly on the surface of the water body in the experimental pool. After using strontium periodate for 1 hour, spray polyaluminum chloride with a concentration of 50ppm evenly on the surface of the water body ; After the cyanobacteria in the water body are flocculated into pieces, they are manually salvaged, and the salvaged cyanobacteria are filtered out of the water by mechanical pressure, and the water is returned to the experimental pool.

[0014] Strontium periodate can not only kill cyanobacteria, but also quickly kill bacteria and some viruses in water, and can efficiently aid coagulation, adsorption and degradation of refractory organic matter, cyanide, sulfide, methyl mercaptan, ammonia, nitrite and Heavy metal polluta...

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...
