摘　　要：文中综述了氰化物的危害和含氰废水的来源以及目前处理含氰废水的方法。以工程实例重点介绍亚铁蓝法处理此废水的应用。亚铁蓝法除氰可分二级进行,第一级在中性条件总氰去除率达到80%以上,第二级直接在一级出水加碱调pH至8～9沉淀即可,通过二级处理总氰去除率达到95%左右。This paper reviews the hazards of cyanide,the source of cyanides-contained wastewater and some methods to treat the wastewater at the present.It also take a project as an example to emphatically introduce the application of ferrocyanide process to the wastewater treatment.Ferrocyanide process of cyanide removal can be carried out by two steps.In the first step reaction under a neutral condition,the total cyanides removal rate reachs over 80%.The second step reaction is precipitation by adding alkali in the first-step effluent to adjust pH to 8~9.After the two-step treatment,total cyanides removal rate is about 95%.
