FIELD: chemistry.
SUBSTANCE: invention relates to methods for sorption purification of water from petroleum products and can be used in environmental protection. The method of purifying waste water from petroleum products involves mechanical purification and post-purification by filtering through a layer of fixed sorbent. The sorbent used is carbonate sludge from clarification tanks of thermal power plants dried to 3-20% moisture content, having the chemical composition CaCO3+MgO+Mg(OH)2+SiO2+Fe(OH)3+Al(OH)3. The sludge is formed from combined coagulation a heptahydrate of iron sulphate and lime treatment of natural water with a saturated solution of lime milk at the water treatment plants of thermal power plants.
EFFECT: invention reduces residual concentration of petroleum products in the filtrate to 0,01 mg/dm3.
