METHOD FOR RECOVERING VALUABLE MATERIALS AND TREATING WASTE WATER USING MICROALGAE FOR PRODUCING BIODIESEL

摘要

The present invention relates to a method for culturing freshwater microalgae for producing biodiesel from waste water which cultures strains of the freshwater microalgae in waste water, respectively collects crystalline materials and amorphous materials, and processes waste water by removing nitrogen, phosphorus, organic carbon and inorganic carbon from waste water at the same time. According to the present invention, economic efficiency of culturing microalgae can be increased using waste water pollution source as a growth source of microalgae strains, and concurrently culture the microalgae and process waste water. In addition, the produced biomass can be made into biodiesel, the biomass and precipitated effective materials can be utilized as a soil improver, a fertilizer, and the likes so that production of new renewable energy and use of waste as a resource can be possible at the same time.
