Sealed continuous culture experimental apparatus based on simulation of microalgae amplification culture

Abstract

The invention discloses a sealed continuous culture experimental apparatus based on simulation of microalgae amplification culture. The apparatus comprises a first tubular photo-bioreactor and a second tubular photo-bioreactor which are connected in parallel, a gas-circulating system, a liquid circulating system, a data acquisition system and a constant-temperature water system, wherein the firsttubular photo-bioreactor and the second tubular photo-bioreactor are placed in a constant-temperature water tank, and are respectively provided with a liquid inlet, a gas inlet, a liquid discharge port and a vent port; the gas-circulating system is connected between the gas inlet and the gas outlet; the liquid circulating system is connected between the liquid inlet and the liquid discharge port;and the constant-temperature water system is connected with the constant-temperature water tank. According to the invention, the advantages of a culturing system for researching the microalgae growthmechanism and amplification culture are combined, and the advantages of the tubular photo-bioreactors are also utilized, thus the environmental parameters for microalgae amplification culture are optimized, and the capabilities of microalgae for fixing CO2 and treating different waste gases and wastewater are researched.

Description

technical field [0001] The invention relates to an experimental device for cultivating oil-producing microalgae, in particular to a closed continuous culturing experimental device based on the expanded cultivation of simulated microalgae. Background technique [0002] Microalgae can fix a large amount of CO during photoautotrophic culture 2 , organisms on the earth can fix 8×10 10 t carbon, produced 14.6×10 10 t biomass, more than half of which is attributable to algae photosynthesis. will CO 2 Injecting microalgae into biofuel through photosynthesis is a major breakthrough in the field of renewable energy in the past ten years. At the same time, the cultivation of microalgae can be combined with the treatment of tail gas and sewage, and the nutrients in the tail gas and sewage can be used. The photobioreactor microalgae cultivation device realizes the continuous synthesis of microalgae oil through recyclable photosynthesis, laying the foundation for high-throughput pro...
