Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of biotechnology, more particularly to a microalgae production monitoring device. BACKGROUND

[0002] As an important biological resource, microalgae has a wide application prospect in the industries of biological energy, food, medicine, etc. At present, microalgae production and cultivation mostly adopt transparent pipeline type bioreactors, which have the advantages of providing a large surface-to-volume ratio, being conducive to light and gas exchange, and thus promoting the growth of microalgae. The principle is to realize large-scale production by high-density cultivation of microalgae in the pipeline and taking advantage of the characteristics of photosynthesis and fast growth of microalgae. Specifically, the microalgae pipeline bioreactor continuously flows the microalgae seeds under light and nutrient conditions, so that they are cultured in high density in the pipeline.

[0003] However, the growth and metabolism monitoring of microalgae during the production and cultivation process is of great significance. The existing monitoring means mostly rely on the monitoring of environmental parameters by sensors, such as temperature sensors, pH sensors, light intensity sensors, etc. These sensors can provide real-time data of environmental parameters, but cannot directly reflect the growth state of microalgae. Only by naked eye or microscope observation or indirect parameter inference can the growth state of microalgae be speculated, which limits the accuracy and timeliness of monitoring. Due to the lack of real-time monitoring of the growth state of microalgae, it is difficult to adjust the cultivation conditions in time, which may lead to poor growth of microalgae or failure of cultivation. In large-scale production, manual observation and adjustment of cultivation conditions are not only inefficient, but also costly. Therefore, in order to improve the production efficiency and quality of microalgae, a monitoring device capable of monitoring the growth state of microalgae in real time is needed to more accurately control the cultivation conditions and optimize the growth environment of microalgae.

[0004] However, there is no effective solution to the problems in the related art. TECHNICAL CONTENT
