S10: the micro-algae collection assembly according to any one of claim 9-10 is placed in both culturing microalgae bioreactor (10);
S20: second bar (102,202) of at least two micro-algae collection devices (100,200) described in being pulled upwardly, every layer of collecting board (103,203) to be tilted the first angle of inclination relative to horizontal direction, and make every layer of collecting board (103,203) keep the first angle of inclination static first scheduled time, thus micro-algae is made to be deposited on the protruding bight (103a, 203a) at the first end place of every layer of collecting board (103,203);
S30: after micro-algae deposition, discharge the micro-algae clear liquor in described both culturing microalgae bioreactor (10);
S40: put down the second bar (102,202) and first bar (101,201) of at least two micro-algae collection devices (100,200) described in being pulled upwardly, every layer of collecting board (103,203) to be tilted the second angle of inclination relative to horizontal direction, thus makes micro-algae of deposition flow into both culturing microalgae bioreactor (10) from second end (103b, 203b) of the opening of every layer of collecting board (103,203);
S50: discharge the micro-algae in described both culturing microalgae bioreactor (10), thus complete the collection of micro-algae.
17. Microalgae collection method according to claim 16, is characterized in that, between described step S10 and step S20, also comprise step:
S12: first bar (101,201) of at least two micro-algae collection devices (100,200) described in being pulled upwardly, make every layer of collecting board (103,203) relative to horizontal direction inclination the 3rd angle of inclination, then in both culturing microalgae bioreactor (10), add flocculation agent and pass into gas to the bottom of both culturing microalgae bioreactor (10), thus making flocculation agent and both culturing microalgae liquid Homogeneous phase mixing.
18. Microalgae collection method according to claim 15, is characterized in that, described 3rd angle of inclination is 60 ° ~ 75 °.
19. Microalgae collection method according to claim 17, is characterized in that, described flocculation agent is inorganic cation saline flocculating agent, polymer organic flocculation agent or microbial flocculant.
20. Microalgae collection method according to claim 19, is characterized in that, described flocculation agent is aluminium salt, molysite or chitosan.
