FIELD: technological processes; chemistry.
SUBSTANCE: method includes mixing of oil containing sewage waters with magnet liquid that contains hydrocarbon fraction with stabilised magnet particles, and mixture separation. Process of mixing is carried out with ratio of magnet liquid: oil product contained in sewage waters, equal to (0.0005-0.001):1. Separation of prepared mixture into purified water and mixture that contains magnet liquid and magnetised oil products is carried out in magnet separator with intensity of magnet field of 9-14 kA/m. Besides, mixing is carried out for 20-25 minutes.
EFFECT: improvement of oil containing sewage waters purification; increase of oil products extraction extent and improvement of environmental situation.
