FIELD: waste water treatment.
SUBSTANCE: cyanide effluents are treated with alkali or alkali-earth metal metabisulfite in presence of copper catalyst and residual cyanide and thiocyanate are subjected to bacterial destruction using strains Pseudomonas putida 21 and Pseudomonas stutzeri 18.
EFFECT: enabled detoxification of effluents within a wide cyanide and thiocyanate concentration range and therefore allowed use of the method for cleaning waste waters and slurries in gold mining, galvanic, pharmaceutical, and in a number of other industries.
