FIELD: waste water treatment. SUBSTANCE: method involves coagulation, flotation, and sorption. Flotation is performed in activated aqueous air dispersion, to which sorbent, in particular fired vermiculite is added. When waste water is treated to remove petroleum derivatives, weight ratio of vermiculite to the latter ranges between 1:1 and 1:15. Before firing, size of vermiculite should be at least 0.5 mm. Method allows creation of module installations and purification of water to oil levels below 0.05 mg/l. Method can be, in particular, applied at mining plants, in chemical industry, etc. EFFECT: enhanced oil removal efficiency. 3 cl, 1 tbl, 4 ex |
