Closed slope type raceway pond system used for large-scale culture and harvesting of microalgae

Abstract

The invention discloses a closed slope type raceway pond system used for large-scale culture and harvesting of microalgae, belonging to the field of large-scale culture of microalgae. The system mainly comprises a raceway pond subsystem used for microalgae culture, a microalgae solution adjusting subsystem and a microalgae harvesting subsystem. The culture subsystem used for microalgae culture isprovided with a raceway pond with a reserved slope, so that a microalgae solution can flow along the raceway pond under the effect of gravity, and thus the energy consumption for driving the microalgae solution to flow is greatly reduced; the raceway pond is coupled with a closed photobioreactor, so that the purposes that the manufacturing cost is low, the operation is simple and convenient, the culture conditions are easy to control, and the pollution by the environment is little are achieved; the real-time harvesting of microalgae is realized by utilizing a filtering membrane, and thus the harvesting cost is greatly reduced.

Description

technical field [0001] The invention relates to a closed slope raceway pool system for large-scale cultivation and harvesting of microalgae, belonging to the field of large-scale cultivation of microalgae. Background technique [0002] Algae is a general term for organisms that have no differentiation of roots, stems, and leaves, and live in a photoautotrophic mode. Among them, the tiny algae that need to be observed with a microscope are called microalgae, including cyanobacteria, green algae, red algae, Numerous eukaryotic and prokaryotic organisms capable of photosynthesis, such as brown algae, golden algae, and dinoflagellates, as well as some heterotrophic and symbiotic organisms. Microalgae have various forms such as unicellular, unicellular population and multicellular individual. Microalgae cells contain a variety of carbohydrates and oils. In recent years, more and more researchers believe that microalgae can be used as excellent nutritional health products and raw...
