The pitch of waves that described cultivation apparatus is formed is less than 30cm, comprises waviness or machicolated form or trapezoidal; The described pitch of waves is preferably less than 25cm, is preferentially less than 20cm further, is further preferably less than 10cm, most preferably 8cm.
Preferably, on the basis of technical scheme provided by the invention, described cultivation apparatus is that level or certain slope are placed; The described gradient is preferably less than 8 degree, is preferably less than 5 degree further, is most preferably less than 3 degree.
Preferably, on the basis of technical scheme provided by the invention, the making material of described cultivation apparatus is transparent material, can be the transparent plastics such as glass or PVC, PE, PMMA, PC, PS, PET, PP.
Preferably, on the basis of technical scheme provided by the invention, described algae liquid backflow storing unit be various can fill liquid bucket or the building materials such as the cement pond of building.
Preferably, on the basis of technical scheme provided by the invention, described lifting gear is pump.
The utility model has the advantages that: this bioreactor, because of the constitutional features that it is special, to have light splitting function, light can be entered into bottom algae liquid by concavo-convex place, makes the abundant light of algae, and reaches the object of algae high-density culture; Need high light to accumulate active substance in micro-algae, during as grease, astaxanthin, can enough illumination be obtained, shorten the microdisk electrode time.Owing to being that open type is cultivated, easily, temperature can not rise to too high in evaporation, reduces cooling cost.Meanwhile, this reactor is easy to make, easily amplifies, easy cleaning etc., is applicable to the micro-algae of industrialized aquaculture.
