APPARATUS FOR ALGAE PRODUCTION USING EFFLUENTS PRODUCED FROM ANAEROBIC DIGESTION OF ORGANIC WASTES

摘要

PURPOSE: An algae producing device using anaerobic digestion effluent of organic waste is provided to perform aerobic treatment of effluent with increase of C/N ratio of liquid waste by converting nitrogen and phosphorus in the liquid waste into algae. CONSTITUTION: An algae producing device using anaerobic digestion effluent includes the following: an acid fermenter(10) decomposing organic waste with acid generating microorganism; a methane fermentation tank(20) decomposing the organic waste by methanogenesis microorganism; an algae culture device(50) synthesizing algae with nitrogen and phosphorus in liquid waste discharged from the methane fermentation tank; an aerobic reactor(60) processing the organic waste discharged from the algae culture device; and a digestive fluid tank(40) dissolving carbon dioxide from a carbon dioxide supply pipe(90).
