Description
Technical Field
The utility model mainly relates to a blue alga mummification field especially relates to a blue alga algae mud low temperature mummification system.
Background
Blue-green algae, blue-green algae, is a large unicellular prokaryotic organism with long evolutionary history, gram-negative property, no flagella, chlorophyll a content, no chloroplast (different from eukaryotic algae) and capability of aerobic photosynthesis. The differences from photosynthetic bacteria are: the photosynthetic bacteria (rhodospirillum) perform a more primitive photosynthetic phosphorylation reaction without oxygen evolution during the reaction, which is an anaerobic organism, whereas cyanobacteria are able to perform photosynthesis and oxygen evolution. Its development has led to the entire earth's atmosphere going from an anaerobic state to an aerobic state, thus gestating the evolution and development of all aerobic organisms. More than 120 kinds of cyanobacteria have nitrogen fixation capability so far, and particularly, aquatic ferns which are symbiotic with Anabaena (Anabaena azolae) of rhododendron dauricum are good green manure. However, some cyanobacteria cause eutrophic seawater "red tide" and lake "water bloom" after being polluted by elements such as nitrogen and phosphorus, and bring serious harm to fishery and aquaculture. In addition, a few aquatic species such as Microcystis, produce toxins that induce liver cancer in humans. Cyanobacteria are widely distributed in the nature, including various water bodies, soil and partial inside and outside of organisms, and even can find their traces on rock surfaces and other severe environments (high temperature, low temperature, salt lake, desert, ice land and the like), and are known as pioneer organisms. They play an important role in rock weathering, soil formation and water ecological balance. In addition, cyanobacteria have economic value, including many food species, such as nostoc commune (nostoc commune, commonly known as nostoc commune, n.commune), Spirulina platensis (Spirulina platensis), and Spirulina maxima (Smaxima), the latter two have been developed into "Spirulina" products of some economic value. The existing device dries the blue algae at low temperature, has large volume and heavy weight, plays a limiting role in the transportation and later-stage recycling of the blue algae, and hinders the recycling of the blue algae.

Compared with the prior art, the invention uses the ultrasonic cavitation technology to destroy the cell structure of the blue algae, so that the intracellular water is converted into free water, thereby being easier to remove; meanwhile, the characteristics of ultrasonic-ozone coupling efficient oxidation and easy decomposition and no residue of ozone are combined, so that the content of the cyanobacteria algae toxins after treatment is greatly reduced, and no chemical substance residue is added; the high-pressure dehydration technology is applied, so that the water content of the dehydrated algae mud is lower, and the drying process is more energy-saving; the low-temperature drying technology is applied to avoid the carbonization of blue algae and the generation of waste gas. The method has the advantages of simple flow, simple and convenient operation, mild reaction, good algae toxin removing effect, no addition of flocculant, large volume reduction and water content lower than 15 percent, and provides a new solution for high value-added recycling of the blue algae.
