Oxidation Treatment of Cyanide-containing Wastewater with Activated Carbon as Catalyzer


This invention involves in oxidation treatment of cyanide-containing wastewater with activated carbon as catalyzer. It includes pre-treatment of cyanide-containing wastewater, catalyzed oxidation treatment and post treatment of activated carbon. This invention takes use of the huge surface area of the activated carbon to strongly adsorb the oxygen in the air and the cyanide in the wastewater first, then under the catalyzing function of bivalent copper ion, non-toxic ammonia and carbonate are formed after reaction. This invention improves workers’ labour load and operation environment, and guarantees treatment effect. It is siutable for for those gold mines in romote area to treat cyanide-containing wastewater, due to its low cost and simple technique.
