Resumen de: CN223805088U

The utility model discloses a microalgae membrane separation and harvesting device, which belongs to the technical field of microbial culture and comprises a liquid storage barrel and a filter channel formed by splicing and combining a plurality of split structures and used for harvesting microalgae, the filtering channel comprises a plurality of split cylinders which are detachably connected, and a plurality of layers of filtering membranes of which the pore diameters are gradually reduced are sequentially arranged in each split cylinder from top to bottom. Microalgae cells are cultured through a columnar photobioreactor, the algae cells are separated through membrane filtration, algae liquid is discharged from the bottom of a cone at the lower end of a column, supernate is discharged in a filtration mode, the algae cells are attached to the membrane, the discharged supernate can continue to culture the algae cells, microalgae mud on the multilayer harvesting membrane is scraped off through filtration, and the microalgae cells are collected through the membrane. The microalgae mud is obtained; therefore, the harvesting cost of large-scale cultured microalgae is reduced, the harvesting time is shortened, and the harvesting efficiency is improved; the cyclic utilization of the culture solution greatly reduces the treatment capacity, and the microalgae culture and harvesting process is simple and convenient to operate.
