The invention relates to a microalgae
cell culture and collection integrated
system and belongs to the technical field of microalgae culture and collection. The culture
system comprises a photoreactor, an air inlet
pipe, a stirrer, an exhausting port and a
light source. One end of the air inlet
pipe is inserted into a culture solution of the photoreactor, the stirrer is arranged in the photoreactor, the exhausting port is formed above the liquid level of the culture solution, and the
light source is arranged inside and / or outside the photoreactor. The
collection system is composed of a filterresidue
bed and a collection
bed, wherein the filter residue
bed is arranged above the collection bed, and the photoreactor and the filter residue bed in the culture
system are connected through a
pipe. The microalgae
cell culture and collection integrated system performs microalgae
cell culture by adopting a
photosynthesis culture process and then quickly collects microalgae cells through a collecting bed with an inclination angle changing from 0 degree to 90 degrees in a continuous or gradient way, thorough separation of the microalgae cells and a culture solution is ensured, the problem ofunsmooth microalgae cell discharging is also effectively avoided, and the microalgae cell collection efficiency is remarkably improved.
