More Information
Summary:Provided are a method and a device for treating wastewater containing organic matter, with which it is possible to use ozone to efficiently remove, by breaking down, organic matter in wastewater containing the organic matter and inorganic carbonates. Water to be treated is subjected to a decarbonation treatment using an inorganic carbonate removal device 3, hydrogen peroxide is added, an ozone-containing gas is added by an ejector 8, the water to be treated is channeled to a static mixer 13, and the organic matter is subjected to an oxidation treatment. The ratio A/B between the ozone concentration A(g/Nm3) of the ozone-containing gas and the inorganic carbonate concentration B (g/L) of the water flowing into the ejector is set to 500-1000.
