PURPOSE: Provided is a wastewater treatment method using advanced oxidation process (AOP) being capable of continuously oxidizing wastewater by installing a light source such as UV lamp radiating UV ray and photocatalyst generating OH radicals with great oxidation ability when they comes into contact with UV ray in an oxidation tank. CONSTITUTION: The method comprises the steps of oxidizing wastewater in a first oxidation tank(1) having photocatalyst, a UV light source(3) and activating gas including ozone (O3) therein, oxidizing effluent of the first oxidation tank(2) in a second oxidation tank having photocatalyst, UV light source(3), adsorbent, and activating gas including ozone (O3) therein, and discharging the treated water of the second oxidation tank(2), wherein the photocatalyst is TiO2 or CuO, and wherein the adsorbent is activated carbon, activated alumina or zeolite.
