Embodiment Construction
[0096] The invention designs a new culture system for microalgae culture. It should be understood that the "system" or "cultivation system" used in the present invention refers to a product, that is, a device or equipment. The new type of microalgae culture system takes the spatial three-dimensional component unit-inclined sloping plate as the main body, and transports the algae liquid in the storage tank to the liquid transportation method such as pump or air-lift or other algae liquid transportation methods. In the overflow tank at the top of the inclined plate, the algae liquid overflows from the overflow tank along the inclined plate into the algae accumulation tank by gravity, and the algae liquid flows back to the storage tank through the algae liquid collection tank.
[0097] When the algae fluid flows along the inclined plate, the sunlight irradiated on the inclined plate can be fully utilized, and the algae cells can fully receive the light. In terms of the light-receiv...

The invention provides an overflow tilting novel microalgae culture system. The culture system comprises an inclined plate subsystem and a microalgae solution circulation subsystem. The inclined plate subsystem contains an inclined plate for supporting a microalgae solution thin-layer, a support frame for supporting the inclined plate and an overflow device used for receiving a microalgae solution and supplying the microalgae solution to the inclined plate. The microalgae solution circulating subsystem contains a device used for conveying the microalgae solution to the overflow device and a collecting unit used for collecting the microalgae solution flowing off from the inclined plate device. The invention also relates to a microalgae culture method. According to the culture method, a microalgae solution is conveyed into an overflow groove through a microalgae solution conveying power source, and the microalgae solution overflows along the inclined plate into a microalgae accumulating groove under the effect of gravity, so as to realize microalgae culture. The culture system of the invention has a simple structure, is low-cost, is convenient for processing and manufacturing, and is simple to operate. What is more crucial is that the culture system has large unit-volume microalgae solution sunlight area and good sunlight illuminating angle so as to effectively enhance light use efficiency of microalgae cells and microalgae cell growth rate. Thus, low-cost, large-scale, high-density and efficient culture of microalgae is realized.
Description
Technical field [0001] The invention belongs to the technical field of microalgae biology, and relates to an overflow inclined novel microalgae culture system and a method for microalgae culture using the system. Background technique [0002] Microalgae are rich in protein, polyunsaturated fatty acids and carotenoids and other high value-added substances. At the same time, microalgae have the ability to absorb nitrogen / phosphorus and accumulate oil during cultivation. Therefore, microalgae have a wide range of applications in food, bait, feed, environmental protection and bio-energy. Especially in recent years in terms of bioenergy, microalgae are considered to be the most promising raw materials for the preparation of biofuels such as biodiesel; in addition, microalgae have great potential for carbon fixation and treatment of nitrogen / phosphorus-rich wastewater. [0003] The photobioreactor is the core device for photoautotrophic culture of microalgae. Currently, there are two t...
