THERMAL PLASMA REACTOR AND WASTEWATER TREATMENT METHOD

摘要

The invention relates to a reactor for the treatment of wastewater solutions containing cyanide and other dissolved organic material, having an elongated tube having an entrance (28) and an exit (32), and an energy source (22) for the tube, preferably positioned adjacent the exit. The energy source generates intense energy such that a cyanide/organic material-containing solution can be treated by passing it through the tube to expose it to said energy so that the solution absorbs sufficient energy from the energy source to degrade the cyanide and/or dissolved organic material contained therein. The source of intense energy is preferably a plasma, e.g. a plasma generated by a plasma torch or a DC electric arc. The invention also relates to a process of treatment of such a wastewater solution by passing it through such a reactor.
