Problems solved by technology

[0006] In the current literature for CO 2 Although both recharge and oxygen desorption processes are involved, in the process of open culture microalgae, CO 2 The problem of supplementation and its low fixation efficiency has not been well resolved. In order to overcome the current CO 2 Unfavorable factors such as unsatisfactory replenishment and oxygen analysis effects, cumbersome process, and excessive investment

Embodiment Construction

[0019] Such as figure 1 and 2 As shown, in the present invention, a liquid ring delivery pump is used for mixing and delivery of gas and liquid, and the liquid comes from an open bioreactor and circulates back to the bioreactor after passing through the liquid ring delivery pump. When the circulating liquid passes through the liquid ring delivery pump, a large amount of CO is dissolved 2 , and circulate back to the open bioreactor after supplementing appropriate amount of nutrients. The circulating liquid is taken from the bottom of the bioreactor and drawn out through the filter device, and the circulating liquid is circulated back to the bottom of the bioreactor.

[0020] The filter device installed at the outlet of the circulating liquid at the bottom of the bioreactor is a metal or plastic filter screen with a mesh size of 1 to 20 microns. At the same time, there is a back-blowing air path connected to the outside of the filter screen. The purpose is to back-flush the f...

Abstract

The invention discloses a method for open-type culture of microalgae, which comprises the following contents: CO2 is supplied into an illumination open-type bioreactor which contains microalgae and a microalga culture medium for the growth of microalgae, wherein the CO2 is supplied by a method which is to mix a CO2-containing gas with a liquid phase by using a gas-liquid mixed conveying device, perform gas-liquid separation in a gas-liquid separator, and deliver a CO2-dissolving liquid phase obtained after gas-liquid separation to the illumination open-type bioreactor to supply the CO2 required by the growth of the microalgae. Compared with the prior method, the method solves the problem of low CO2 utilization rate caused by thinness of a liquid layer in the conventional open-type microalga culture system, improves the fat accumulation capacity in a microalga culture process, improves CO2 utilization rate and simplifies a culture device.

Description

technical field [0001] The invention belongs to the field of microalgae biotechnology, in particular to an open photobioreactor to effectively supplement CO in the process of cultivating microalgae 2 A method for improving the quality of microalgae culture. Background technique [0002] Microalgae are rich in protein, polysaccharides, unsaturated fatty acids and other nutrients (such as spirulina), which can be used in food, medicine and energy; they can accumulate fatty acids in large quantities, and some microalgae, such as chlorella, can account for the dry weight of fatty acids in their bodies 30% to 60% of that. The use of microalgae to accumulate oil resources has become the most popular research field in the development of renewable resources using solar energy. Not only has strong market potential, but also has extraordinary social value. [0003] There are generally two types of microalgae cultivation methods: closed type and open type (or open type). The open ty...
