FIELD: chemistry.
SUBSTANCE: invention concerns methods of water treatment and can be applied in elimination of organic contaminants of various origin, such as synthetic surfactants, oil products, phenols, from reverse and waste water. Method includes oxidation by hydrogen peroxide, irradiation with UV rays and use of catalyst based on soluble titanium salts. Hydrogen peroxide is used in amount of 10-20 mg/l, and soluble titanium salt is taken at the rate of 0.1-0.2 mg of Ti per litre of treated water. Aeration is performed at the air flow rate of 0.5-1 l/l, and wave lengths of 253.7 nm and 185.6 nm are used for further UV irradiation.
EFFECT: simplified treatment process, reduced power input, increased purification degree.
