Industrialized culture method and device for photosynthetic autotroph

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.

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 ex
