| abstract | (57) [Summary] [Purpose] To deal with serious water pollution, pesticides and organic solvents (especially halocarbons) and surfactants (especially those with side chains) that are difficult to treat with the current activated sludge method etc. Stuff) It is an object of the present invention to provide an economical wastewater treatment method capable of easily and quickly treating such as mild water to obtain safe water. [Structure] Put water to be treated such as wastewater in a container coated with titanium oxide film inside, add hydrogen peroxide and copper ion or copper salt, and irradiate light such as sunlight, or add copper ion By putting the water to be treated and hydrogen peroxide into a container coated with the titanium oxide film inside and irradiating it with light, the organic substances contained in the water to be treated are quickly completely oxidized into carbon dioxide gas and water, It is decomposed to obtain purified water. The wastewater treatment method according to the present invention is a very economical method because hydrogen peroxide used is inexpensive, the amount of copper salt used is extremely small, and a waste liquid containing copper ions can also be used. |
