Abstract

The invention relates to the field of microalgae biology, and discloses a method for collecting microalgae and an application thereof. The method comprises: (1) subsiding the cultivated microalgae culture solution, so that the microalgae culture solution forms an aggregated microalgae suspension and a supernatant; (2) suspending the aggregated microalgae in a moving manner by using a sucker The liquid is harvested, and the harvested aggregated microalgae suspension is sent to the next-level processing device through the conveying device communicated with the suction cup. Under the condition that the microalgae harvesting amount is basically not affected, the method of the present invention does not need to transport and filter all microalgae culture fluids, and has small processing capacity, high processing efficiency and low cost.

Description

Technical field [0001] The present invention relates to the field of microalgae, and in particular, to a microalgae collection method and its application thereof. Background technique [0002] Microalgae is a single-cell organism that is widely distributed, fast growth, simple structure. Through its own unique metabolic process, a variety of unique valuable compounds can be generated, including polysaccharides, proteins, vitamins, fatty acids and fatty acid fats, are a very promising economic crop. While the growth of microalgae is, a large amount of carbon dioxide can be fixed, which is significant for the significance of the carbon dioxide in the atmosphere. [0003] Due to the small volume of microalgae, the concentration in the water is low, and the concentration is not more than one percent, which makes it very difficult to collect in the microalgae culture, and the cost is also very huge. Currently, commonly used microglasia collection methods include centrifugal separation...
