Technical field
The present invention relates to a kind of blue-green algae composition and use thereof that contains.
Background technology
Blue-green algae is an algae bio, has another name called blue-green algae, is the unicellular algae plant, and in all algae bios, blue-green algae is that the simplest, primary is a kind of.All blue-green algaes all contain a kind of special blue pigment, and therefore blue-green algae gains the name.
In some nutritious water bodys, some blue-green algae often breeds in a large number summer, and forms one deck blue-greenish colour and stench floating foam of distinguishing the flavor of is arranged at the water surface, is called " wawter bloom ".Blue-green alga bloom easily causes water quality deterioration, exhausts water oxygen gas when serious and causes the death of fish.Even more serious is that some kind (as Microcystis aeruginosa) also can produce harmful algae toxin in the blue-green algae, causes serious environmental problem.
So far, do not form a kind of treatment process of energy-conserving and environment-protective as yet for blue-green algae.The blue-green algae of salvaging contains large quantity of moisture (water content reaches more than 95%).Blue algae dewatering not only needs special equipment, and consumes energy huge and inefficiency.Therefore, how economical, efficient and " cleaning " handle blue-green algae, turning waste into wealth just becomes the technical issues that need to address of the present invention.
