Biological reaction method and bioreactor
In a bioreactor, a culture solution derived from a cultivation tank is separated into bacteria cells and filtrate by a bacteria cell filter. The filtrate is introduced from the bacteria cell filter into a micro-nano bubble generation tank where micro-nano-bubbles are mixed with the filtrate. The filtrate containing micro-nano-bubbles is returned to the cultivation tank to activate the microorganisms therein, so that a biological reaction time is reduced by the activated microorganisms.
1. A bioreactor comprising:
a medium reservoir for storing a culture solution for microorganisms as seed bacteria;
a seed bacteria cultivation tank for cultivating the microorganisms to be put in with a mixture of the culture solution supplied from the medium reservoir and micro-nano-bubbles;
a biological reaction tank for cultivating the microorganisms with solution supplied from the seed bacteria cultivation tank;
a bacteria cell filter for receiving the culture solution from the biological reaction tank and separating the culture solution into bacteria cells and filtrate;
a first micro-nano bubble generation tank for receiving the filtrate from the bacteria cell filter and having a micro-nano bubble generator, adding the micro-nano-bubbles to the filtrate by the micro-nano-bubble generator, and introducing the filtrate containing the micro-nano-bubbles into at least the former of the biological reaction tank and the seed bacteria cultivation tank;
a filtrate reservoir being a second micro-nano bubble generation tank for receiving the filtrate from the bacteria cell filter and adding the micro-nano-bubbles to the filtrate; and
a distiller for receiving the filtrate containing the micro-nano-bubbles from the filtrate reservoir and distilling the filtrate containing the micro-nano-bubbles.
2. The bioreactor set forth in claim 1 , further comprising
an air supply section for supplying air disinfected with a disinfection filter to the seed bacteria cultivation tank and the biological reaction tank, and for aerating and stirring the seed bacteria cultivation tank and the biological reaction tank.
3. The bioreactor set forth in claim 1 , further comprising:
a medium adjustment tank for adjusting a plurality of raw media materials; and
a sterilization section for sterilizing the raw media materials adjusted in the medium adjustment tank and introducing the sterilized raw media materials into the medium reservoir.
4. The bioreactor set forth in claim 1 , wherein
the filtrate reservoir has a micro-nano bubble generator.
5. The bioreactor set forth in claim 1 , wherein
a filler material is placed in the biological reaction tank.

the filler material is a string-type polyvinylidene chloride filler.
7. The bioreactor set forth in claim 1 , wherein
a filler material is placed in the seed bacteria cultivation tank.
8. The bioreactor set forth in claim 7 , wherein
the filler material is a string-type polyvinylidene chloride filler.
9. The bioreactor set forth in claim 1 , wherein
the biological reaction tank and the seed bacteria cultivation tank are filled with a filler material.
10. The bioreactor set forth in claim 9 , wherein
the filler material is a string-type polyvinylidene chloride filler.
