PURPOSE: A treating method of wastewater using activated microorganism is provided, which is characterized in that a settling pond and an aeration tank are installed to activate microorganism group. CONSTITUTION: A method is composed of a settling pond(1,5), controlling tanks(2,3,4) of wastewater level, an aeration tank(3), and controlling tank(8) of microorganism. Microorganism group is cultivated and activated using mineral component, so organic matters are adsorbed and metabolized. Microorganisms are fixed on the media in the contacting aeration tank(4), and activated in the controlling tank(7). Activated microorganisms are cultivated again with returned sludge in the controlling tank(8), and flocculated by coagulation and polymerization. Floc is filtered in the filtration tank(6), and concentrated(9).
