| Abstract: | The method of efficient reduction high concentration cyanide-containing waste water with ferrous sulfate new technology was studied.The purificatory rate is greater than 99.99%. Waste residue in treatment processis recovered and sodium ferrocyanide is prepared. The quality of production comes up to state standard.The technology removes the second pollution and increases economical benefit. |
| Keywords: | cyanide-containing waste water treatment ferrous sulfate waste residue recovery sodium ferrocyanide |
