Setting the neutralization of cyanide in metallurgical industries hydrowave method. Installation for the disposal of cyanide in metallurgical industries based on company work experience for the destruction of chemical agents (CA) hydrowave method. Practically, in the absence of baseline data, it is assumed by the apparatus to carry out hydrodynamic mixing cyanide with an aqueous solution of [ссылка] coagulant-flocculant (ASCF) at the molecular level (patent and production companies). In this case the interaction of cyanide with sulfur in the composition (ASCF) formed salt - thiocyanates, which are a result of high coagulating power and flocculated (ASCF) easily precipitate and act on recycling. Water returns to the working process. By increasing the intensity of high hydrodynamic effects on the solution of cyanide with the water may make the process of destruction of cyanide molecules into simple, [ссылка] components of the periodic output when the level of security controlled by a [ссылка] method. In this case the supplies may not be available. Dates of work on the creation of installation - 6 months. Consumption of specific electrical energy - < 50 [ссылка].
