Problems solved by technology

At present, most of the research is carried out by dynamic centrifugation, and hollow fiber membrane is also used. However, centrifugation depends on the centrifuge, which is unfavorable for space flight requirements in terms of power consumption and volume weight. The hollow fiber membrane method has low efficiency, It is easy to block and other problems, so it is urgent to develop a stable and effici

Abstract

The invention discloses a modular alga photobioreactor. An alga culture standard module is connected with an illumination standard module through a bolt; the other side surface of the alga culture standard module is connected with a gas exchange standard module through a bolt; the alga culture standard module is connected with a culture liquid measurement and control unit through a hose; a first liquid inlet of the alga culture standard module is connected with a second liquid outlet of the culture liquid measurement and control unit; a liquid outlet of the alga culture standard module is connected with a second liquid inlet of the culture liquid measurement and control unit; the gas exchange standard module is connected with a gas measurement and control unit through a hose; a first gas inlet of the gas exchange standard module is connected with a second gas outlet of the culture liquid measurement and control unit; a first gas outlet of the gas exchange standard module is connected with a second liquid outlet of the culture liquid measurement and control unit. The modular alga photobioreactor disclosed by the invention is simple in structure and convenient to use, improves the operation stability of the equipment, improves the culture efficiency by 5-8 times, and provides a good standard experimental equipment platform for further optimizing the design and expanding the reaction volume and the like.

Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, and particularly relates to a high-efficiency modular algae photobioreactor, which utilizes the high-efficiency photosynthesis of algae and is suitable for efficient production of algae biomass and CO in life support systems for space flight and submarine navigation. 2 Fixed and O 2 regeneration. Background technique [0002] Since the beginning of manned space exploration, the controlled ecological life support system has been paid attention to as the basis of manned spaceflight, and the CO 2 Remove and O 2 Regeneration is a key technology in the study of controlled ecological life support systems. Microalgae have become one of the important organisms in the study of controlled ecological life support systems due to their good adaptability, simple cultivation, stable operation, and efficient and rapid production of food and oxygen required by space crew. The growth of microalgae depend...
