FIELD: chemical industry; petrochemical industry; engineering industry; other industries; methods of the electrochemical purification of the industrial waste waters from the suspended particles and the oil products.
SUBSTANCE: the invention is pertaining to the methods of the electrochemical purification of the industrial waste waters containing the suspended substances and the oil products, and may be used at purification of the waste waters of the enterprises in metallurgical, machine-building and other industries. The industrial waste waters are subjected to the electroflotocoagulation at the electric current density of 2-60 A/m2 with usage of the soluble anodes made out of aluminum for 1.3-2.5 minutes, and before the settling the being purified waste water is treated with the water solution of polyacrylamide with the concentration of 2-10 mg/l. The technical result of the invention is the increased degree of purification of the industrial waste waters, simplification of the production process and its hardware set.
EFFECT: the invention ensures the increased degree of purification of the industrial waste waters, simplification of the production process and its hardware set.
