FIELD: chemistry.
SUBSTANCE: invention can be used for pretreatment of drinking water, for treating recycled, industrial and domestic waste water. The method is realised via treatment in a first settling tank by periodic and successive generation of travelling hydroacoustic waves in the audible and ultrasonic frequency ranges, in a second settling tank - by periodic generation of standing hydroacoustic waves in the audible frequency range, in an acoustic hydrocyclone in a revolving hydraulic stream under excess static pressure, irradiation with intense hydroacoustic waves in the audible frequency range at an automatically tuned frequency corresponding to the resonance frequency molecules of pure water of 12.4 kHz. The acoustic hydrocyclone used is a magnetoacoustic hydrocyclone. Further, the treated water is exposed to a low-frequency electromagnetic field at frequency of 24.8 kHz, which is intensely rotated opposite the movement of the hydrodynamic stream of water and the treated water is also irradiated with UV light. Colloidal particles, heavy metals and oil products are removed by further mixing the treated water with an aluminium oxychloride reagent solution. The wet residue is collected, sorted and dried, and safe and hazardous residues are separately packed for subsequent transportation, treatment and recycling.
EFFECT: method provides quality treatment of large amounts of water with complete environmental safety.
