Description

Algae mud drying pretreatment device and treatment method thereof

Technical Field

The invention relates to the technical field of environmental protection engineering, in particular to a polluted algae mud drying pretreatment device and a treatment method thereof.

Background

Blue algae, also called blue-green algae, is a large single-cell prokaryote which has long evolution history, gram-negative staining, no flagella, chlorophyll a, chloroplast (different from eukaryotic algae) and can perform oxygenic photosynthesis. More than 120 cyanobacteria have nitrogen fixation capability, in particular to water fern red which is symbiotic with Anabaena azollae, which is a good green manure. The application of blue algae in various fields is more and more widespread, the blue algae has high value in nutrition and health care, and the health food of 'spirulina' which is very fire-exploded in the market at present is one of the blue algae, and is favored by people because of rich and balanced nutrition. Blue algae also play an increasing role in bioenergy, and attempts have been made to indirectly utilize solar energy to produce oil, such as ethanol extraction from maize or fuel extraction from algae.

Because blue algae has wide application, firstly, the algae mud in the water area is salvaged by a salvage ship, and then the water solution with the blue algae is simply dehydrated and dried to obtain a dried blue algae product. However, some blue algae are polluted, bacteria, organic matters, algae mud suspended matters, radiation pollutants and the like may be generated, and the simple drying often cannot meet the high requirements on blue algae products, so that the invention needs to design a treatment device capable of treating the harmful matters.
