Problems solved by technology

Existing photobioreactors for microalgae cultivation generally use plexiglass as the tank body, which has average light transmission and thermal conductivity, is easy to damage, and has a high cost; some plastic film is used as the tank body, but it must be used outside the film It is supported by a wire mesh frame and must be placed on a fixed base to prevent the reactor unit from falling down, which is inconvenient to use and difficult to assemble and move

Abstract

The invention relates to an all plastic modular photobioreactor system and a method for cultivating microalgae by utilizing the same. The reactor tank body consists of all plastic closed fasteners, a sealing element, a supporting tube and a cylindrical plastic film which are subjected to modular design. The plastic film is fixed by the upper and lower closed fasteners in an octagonal buckling mode to form the closed reactor tank body. A plurality of reactor tank bodies are combined randomly into the photobioreactor system through gas supply pipelines, water inlet and outlet pipelines, an artificial light source and other auxiliary facilities so as to realize all-weather high-density cultivation of the microalgae. A device and the method provided by the invention can be widely used for microalgae cultivation in laboratories and in the production.

Description

technical field [0001] The invention relates to a bioreactor system used for algae cultivation in the field of biotechnology, in particular to an all-plastic modularized photobioreactor system and its application method. Background technique [0002] Microalgae has a wide range of uses, it is an important bait organism for many aquaculture objects; it can be used to extract high value-added bioactive substances or directly for human consumption; it is an important research in the biodiesel project that has attracted much attention in the development of new energy object; it can also be used for sewage treatment and water environment restoration. The important role played by microalgae in various fields has made the large-scale cultivation technology of microalgae attract extensive attention. [0003] Compared with open culture, closed photobioreactor culture can control the environmental conditions, the yield of microalgae culture is relatively high, and the biological poll...
