Problems solved by technology

At present, the main problems of the general microalgae culture method are: 1) the whole process of open culture, this method faces the risk of pollution, and it is difficult to solve the problem of maintaining the germ line; 2) the whole process of closed culture, this method is costly and difficult to solve the problem of large area; 3 ) high nitrogen culture, it is difficult to solve the difficult problem of nitrogen concentration adjustment, nitrogen poisoning and low carbohydrate and lipid content of microalgae in a high nitrogen culture environment, and the problem of producing high nitrogen wastewater; 4) other existing microalgae culture The method mainly adopts microporous pipeline to transfer CO 2 Blow into the culture medium, due to CO 2 It is high-pressure blowing, while the depth of the ordinary planar culture microalgae culture medium is very shallow, the depth is 15-20 cm, generally not more than 25 cm, CO 2 It is very easy to lose into the atmosphere without being absorbed by microalgae, the cost is high and the carbon utilization rate is low, and it does not have the function of carbon capture of industrial waste gas; 5) The cultivation area is large, the cost is high, and it is difficult to promote industrialization

Embodiment Construction

[0040] see figure 2 , the industrialized cultivation of photosynthetic aerobic organisms, especially microalgae, is divided into three stages and integrates biomass energy production, industrial waste gas carbon dioxide capture, and large-area high-nitrogen, phosphorus, and heavy metal oil spill wastewater treatment as one example. The cultivation was divided into three stages: "Small-area Germline Maintenance Stage 1", "Large-area Open Expansion Stage 2" and "High Carbon and Low Nitrogen Carbon Capture Stage 3". "Small-area germline maintenance stage" uses small-area high-nitrogen and high-density culture to prevent pollution and is used to maintain microalgae germlines. The incubator is designed to combine three-dimensional culture to increase the yield per unit area. After harvesting, the microalgae are put into the "large-area open expansion stage 2", and the open low-density culture is carried out in the eutrophic high-nitrogen and phosphorus heavy metal oil spill sewage...

Abstract

The invention relates to an industrialized culturing method and a device of photoautotrophic microorganism, in particular to micro-algae culturing. The conventional high nitrogen and high density micro-algae culturing method is changed in the method, the culturing is executed by dividing into three stages, namely the germ line maintenance stage, the large area open type low density augmentation stage and the high carbon low nitrogen high density carbon capture stage. The three stages respectively achieve objects of large area micro-algae industrialization culturing with low cost, enhancing carbohydrate content and lipid content of the micro-algae, integrating the micro-algae culturing and the industrial waste gas carbon dioxide capture integrated with the waste water purification. The realization of the micro-algae culturing ensures that the pollution elements discharged into the environment can be reclaimed in a large scale with low cost, the potential usage lies in micro-algae bio-energy manufacture, the industrial waste gas carbon dioxide capture, the large area high nitrogen and phosphorus heavy metal petroleum overflow wastewater treatment, the chemical synthesis and the paper making.
