METHOD OF PURIFICATION OF EMULSION-POLYMERIZED RUBBERS AND LATEXES PRODUCTION WASTE WATER PURIFICATION METHOD Russian patent published in 2005 - IPC

FIELD: environmental protection.

SUBSTANCE: the invention is dealt with the field of environmental protection, in particular, with methods of purification of waste water from a polymer in the form of non-coagulated latex and from tamol including biologically unoxidizable and toxic substances, with which help synthetic latexes are produced. The method of purification of waste water of emulsion-polymerized rubbers and latexes provides for continuous treatment of them with non-organic electrolytes with use of an anti-agglomerating additive - an adsorbent with a consequent separation of the liquid and solid phases. At that, in the capacity of the anti-agglomerating additive - an adsorbent they use a fine-grained waste of water reclamation and water purification cationic exchange КУ-2, which is entered directly in the latex production waste water in amount of 0.5-1.5 kg / kg of a polymer by a solid residue. The method ensures a deep purification of the latex production waste water from polymers and tamol including Keukanol, and also price reduction and simplification of the method of purification.

EFFECT: the invention ensures a deep purification of the latex production waste water from polymers and tamol including Keukanol, price reduction and simplification of the method of purification.
