FIELD: chemistry.
SUBSTANCE: method of purifying waste water from emulsified petroleum products employs a sorbent which contains a mixture of dry magnetite concentrate and self-decomposing electric-furnace slag obtained via dry cooling, followed by treatment of the obtained suspension in a magnetic field. The particle size of the slag is equal to 50-100 mcm and the slag is used in amount of 30-40% of the weight of the magnetite concentrate.
EFFECT: high adsorption capacity of the sorbent owing to inclusion of self-decomposing electric-furnace slag in its composition, high degree of purification of waste water containing emulsified petroleum products and low consumption of magnetite concentrate.
