The present invention relates to a microalgae culturing system using wastewater and a culturing method therefor, and the present invention is configured to supply an organic polluted substance, such as influent water of an aeration tank or effluent water of a livestock manure disposal site, to a microalgae culture fluid of a microalgae culturing apparatus, and thus can proliferate and culture high density of microalgae in quantity, remove the organic polluted substance (e.g., nitrogen or phosphor) through the proliferated microalgae to reduce the contamination of wastewater, and, particularly, utilize the high density of microalgae, which are cultured in quantity through the proliferation, for the production of biofuel, thereby expecting effects of reducing the cost for culturing microalgae for biomass acquisition and raising the disposal efficiency of the organic polluted substance.
