| abstract | (57) [Abstract] [Problem] To sufficiently dissolve ozone in wastewater, Provided is a wastewater treatment method and apparatus capable of efficiently converting dissolved ozone to hydroxy radicals and sufficiently removing organic matter in wastewater without adding an ultraviolet irradiation device. SOLUTION: The wastewater treatment method according to the present invention includes an acid supply step of supplying acid to wastewater containing organic matter, an ozone supply step of supplying ozone to wastewater supplied with acid, and a wastewater supplied with ozone. And an ultraviolet irradiation step of irradiating the wastewater supplied with the alkali with ultraviolet rays. In this case, ozone can be dissolved at a high concentration by lowering the pH of the wastewater by supplying the acid. In addition, by raising the pH of the wastewater by supplying an alkali, radicalization of ozone by ultraviolet irradiation can be promoted. As a result, hydroxyl radicals are sufficiently generated in the wastewater, and the wastewater can be efficiently treated. |
