FIELD: technological processes.
SUBSTANCE: invention relates to methods and devices for treating waste water. For waste water treatment, coagulants and air are introduced in the form of aerosol into dirty water by means of suction due to vacuum inside it, created by changing the speed gradient from 100 to 900 s-1 during generation of magnetic field with average intensity from 80,000 to 400,000 A/m and field inhomogeneity from 8,000 to 40,000 A/m2. Flotation is performed not later than 25 minutes. An iron-containing solution with iron concentration of 5 to 250 mg/l is used as coagulant.
EFFECT: higher efficiency of waste water treatment.
