摘　　要：针对黄金冶炼企业氰化浸出产生的含氰废水,通过对离子解离、氧化和沉淀溶解特性的试验研究,初步掌握了主要金属络离子的解离特性和主要组成离子的氧化特性,以及处理过程中产生的主要沉淀的溶解特性。并基于此,提出了不同离子组成的含氰废水的几种相对可行的降氰方法和工艺,有效提高了试验研究效率。Based on the experimental study on the dissociation,oxidation and precipitation dissolution characteristics of cyanide containing wastewater produced by cyanide leaching in gold smelting enterprises,this paper preliminarily mastered the dissociation characteristics of main metal complex ions,the oxidation characteristics of main constituent ions,and the dissolution characteristics of main precipitation produced in the treatment process.Based on this,several relatively feasible cyanide reduction methods and processes for cyanide containing wastewater with different ion composition are proposed,which effectively improves the experimental research efficiency.
