Abstract
The invention relates to the field of microalgae cultivation engineering, in particular to an aeration type optical bioreactor for cultivating microalgae and a method for applying the same. The bioreactor comprises an annular wading pool, a liquid inlet main pipe, an annular liquid replenishing pipe, an atomization nozzle, a hot water pipe coil, an air inlet main pipe, an annular air inlet trunk pipe, an air distribution branch pipe and an aeration device. The bioreactor is characterized in that density difference between microbubbles generated by the aeration device through aeration and peripheral algae liquid promotes the floating of the microbubbles and the declining of the algae liquid; countless gas liquid generated by the annular wading pool circulates and flows up and down so that the upper layer and the lower layer of the algae liquid are mixed; the floating of the bubbles strengthens desorption of dissolved oxygen in the algae liquid; oxygen is taken to the liquid level by the bubbles and is released; and carbon dioxide gas is aerated and simultaneously dissolved in the algae liquid to provide a carbon source for the growth of the microalgae. The invention combines the advantages of an open type optical bioreactor and a closed type optical bioreactor to form a novel closed type optical bioreactor which can use the carbon dioxide gas as the carbon source and cultivate the microalgae in low cost and large scale.
Description
[technical field]
The present invention relates to little algae culturing engineering field, specifically a kind of aeration type bioreactor and application method thereof of cultivating little algae.
[background technology]
Little algae can effectively utilize luminous energy, carbonic acid gas and inorganic salt, the biologically active substance of synthetic fat, protein, polysaccharide and multiple high added value.Along with the continuous intensification of the mankind to little algae understanding, develop and develop new and effective bioreactor and cultural method thereof, become an important component part of little algae biotechnology.
At present, little algae is cultivated and mainly contains open and closed two kinds of bioreactors.Open bioreactor mainly contains four types: on-swimmer's pool, circulatory pool, runway pond, pond.Wherein, the most typical, the most the most frequently used open pond culture systems is the runway pond reactor of Oswald (1969) design, and in fact such culture systems is exactly thousands of square metres of floor spaces, and the nutrient solution degree of depth is the shallow annular pond about 20 centimetres; With the natural light is light source and thermal source, relies on the rotation of paddle wheel (paddle wheel) or pivot arm (rotating arm), makes nutrient solution mix in the pond, circulate, and prevents the efficiency of light energy utilization of frond precipitation and raising frond cell.Though it is simple, with low cost, easy and simple to handle that open bioreactor makes up, there are shortcomings such as vulnerable to pollution, culture condition instability in it, can only be used for little algae cultivation that minorities such as spirulina, chlorella and salt algae can tolerate extreme environment.And the closed reactor culture condition is stable, but high-density culture is easily carried out in aseptic technique, has become developing direction from now on.Compare with open bioreactor, closed photo bioreactor has the following advantages: 1. pollution-free, can realize single kind, purebred cultivation; 2. culture condition is easy to control; 3. the culture density height is easily gathered in the crops; 4. the light autotrophy that is suitable for all little algaes is cultivated, and is particularly suitable for the production of little algae meta-bolites; 5. the ratio of higher illuminating area and volume of culture is arranged, and luminous energy and carbonic acid gas utilization ratio are higher.Therefore, development of closed photo bioreactor at home and abroad in recent years and development and use are very fast, and some has realized the high-density commercialization cultivation of little algae.At present closed photo bioreactor has: duct type, flat, column air lift type, stirred-tank fermenter, vertical Pig, floating bag film etc.
Existing closed photo bioreactor causes easily more or less that dissolved oxygen is accumulated, variety of issues such as under-supply, the flow blind angle of carbonic acid gas, equipment manufacturing cost costliness when the sticking wall of frond, high-density culture, except pipeline reactor, substantially all be in laboratory scale, volume is no more than 1 cubic meter.Though and the annual output that the duct type bioreactor is reported has at present reached up to a hundred tons of algae powder, the cost of this equipment and maintenance cost are very high, are difficult to popularize.
In fact, no matter which kind of design form bioreactor adopts, and develops the closed photo bioreactor of a kind of successful little algae of cultivation, all should follow following principle: (1) high illumination surface to volume ratio; (2) higher gas exchange efficiency; (3) Recycle design of Shi Heing; (4) improve route of transmission, distribution and the quality of light; (5) prevent the accumulation of harmful secondary metabolite; (6) more easily realize the optimal control of culture condition; (7) reduce manufacturing cost as far as possible.Can predict, the sort of cost is low, volume big, the more rational closed photo bioreactor of design should be the emphasis and the developing direction of exploitation.
What the carbon source that little algae is supplied with in culturing process was the most frequently used is sodium bicarbonate, this cost accounts for 40～70% of raw materials cost, if with the carbonic acid gas is that carbon source replaces sodium bicarbonate, its utilization of carbon source rate height, low price, can reduce cost significantly, the cost of carbon source can reduce about 90% in theory.Be that the bioreactor of carbon source must guarantee that carbon dioxide is disperseed well and absorbs with the carbon dioxide, and the oxygen that little algae produces is by desorb effectively, and the uniform and well blend of nutrient solution.
