FIELD: water treatment processes.
SUBSTANCE: process comprises treatment of oil-containing waste water with polymer- colloid complex prepared by mixing a colloidal solution of aluminum pentahydroxochloride having molar ratio Cl-/Al3+ = 0.46-0.52 with 0.1-1.0% aqueous solution of polyacrylamide at molar ratio Al3+ to polyacrylamide unit (6-10):1, wherein polymer- colloid complex is used in amount 1.5-5 mg/L. Process is applicable to treat industrial waste waters of refineries and petrochemical plants as well as petroleum storage depots, oil fields, and enterprises, wherein production cycles involve formation of effluents containing petroleum and petroleum processing products.
EFFECT: simplified technology and equipment and increased oil removal degree.
