METHOD AND SYSTEM FOR PRODUCING BIOGAS, FAT SOLUBLES MATERIAL AND MICROALGAE BY MICROALGAE CULTURE OF ORGANIC WASTE

摘要

PURPOSE: A method and an apparatus for generating biogas, lipoid soluble material, and microalgae is provided to obtain microalgae and lipoid soluble materials without the damage of cells and to cost effectively treat organic waste. CONSTITUTION: Organic waste is fermented to generate organic wastewater and biogas in an organic waste fermenting unit(10). The generated biogas is collected in a biogas collecting unit(20). Diluted organic waste cultivates microalgae containing lipoid materials. The microalgae cultivated liquid and a lipoid material extracting solvent are mixed to contact the lipoid material extracting solvent with the microalgae cultivating liquid. The lipoid materials of the microalgae cultivating liquid are dissolved in the lipoid material extracting solvent. Microalgae is coagulated and separated from the mixture. Remaining mixture is separated into the dissolved lipoid material-lipoid material extracting solvent and water.
