摘　　要：针对某黄金冶炼厂极高浓度含氰废水中污染物的组分分析结果,采用酸化法及OOT或GOC清洁药剂联合工艺对其中的氰化物、硫氰酸盐及铜进行了酸化、氧化和回收利用;同时,对药剂成本、动力成本及经济效益进行了核算。其治理工艺试验结果表明,利用酸化法及清洁药剂氧化联合工艺对极高浓度含氰废水进行深度治理后,回收利用及治理效果均很好,无二次污染,且经济效益、环境效益显著。According to the analysis result of the pollutant compositions in waste water containing very high concentration of cyanide from a gold smeltery, the combined use of acidization and OOT or GOC cleansing oxidants to acidize,oxidize and recover cyanide,thiocyanate and copper. Inthe meantime, the costs of agent usage and power consumption and the economic profits are checked. The experiment results in the treatment process show that the combined use of acidization and OOT or GOC cleansing oxidants in the treatment of waste water contaiming very high concentration of cyanide performs well in recovery and treatment with no secondary pollution, providing very significant economic and environmental profits.
