Abstract

The invention discloses a bag photobioreactor made of flexible films and a photobiology culture system comprising the same. A fluid inlet / outlet for injecting and discharging photobiology culture fluid is formed on the photobioreactor, and an aerating device is arranged in the photobioreactor. The photobioreactor is characterized in that at least a vertical linear isolation strip is formed in the photobioreactor and is used for dividing the photobiology culture fluid in the photobioreactor into a plurality of fluid columns with bottoms communicated with each other; the aerating device is used for injecting gases into the photobiology culture fluid via the bottoms of the fluid columns; and the gases include the reaction gases required for photobiology growth. The photobioreactor has the following beneficial effects: the gases injected by the aerating device can flow smoothly along the vertical fluid columns from bottom to top, so that the photobiology and reaction gases in the photobiology culture fluid can fully react, and the photobiology culture fluid can be fully stirred by the gases, thus improving the light intercepting efficiency of the photobiology.

Description

technical field

[0001] The invention relates to the technical field of photobiological cultivation, in particular to a film-type photobioreactor and a preparation method thereof, a photobiological cultivation system and method. Background technique

[0002] At present, the industrial production of microalgae still generally adopts the open pond culture system, which has the advantages of less investment, simple operation and easy production, but has the following disadvantages: (1) It is easily affected by the external environment, and it is difficult to maintain a suitable temperature (2) It will be polluted by dust, insects and miscellaneous bacteria, and it is difficult to maintain high-quality single algae culture; (3) Water is easy to evaporate; (4) The ratio of light area to culture volume is low, light energy and CO 2 The utilization rate is not high, and high-density cultivation cannot be realized; (5) harmful substances such as heavy metals are easy to accumulate in...
