Description

Technical Field

[0002] Since the commercial cultivation of microalgae began in 1957, it has been nearly 70 years, and it has been widely used in the fields of food processing, aquaculture, medicine and beauty, wastewater treatment and environmental protection, bioenergy, biochemical and biomanufacturing. Microalgae cultivation needs to be expanded step by step, and generally adopts a three-level expansion mode, with the first, second and third levels corresponding to volumes of ~5L, 50-100L, and ≥1000L respectively. Among them, the secondary culture device generally adopts two modes, one is to use a disposable transparent plastic bag, and the other is to use a box-type water tank made of glass or acrylic. The former needs to be replaced every time, which consumes labor and is easily scratched; the latter has square dead corners, resulting in problems such as algae attachment and insufficient cleaning. The existing patent CN200820057106.5 (announcement date May 27, 2009) discloses a microalgae cultivation photobioreactor, whose fixing method is too simple, which easily leads to the easy peeling of the bottom of the bioreactor and its main body.
