摘　　要：研究了在pH=3时,在Fenton试剂存在下,水中氰化物与Fe2+、H2O2反应,通过分离生成的亚铁氰化铁沉淀,高效去除了氰化物。除氰过程中,Fenton起到了协同和强化作用,用于焦化废水的深度处理,总氰化物的去除率达到98%以上,浓度低于0.1mg/L,并有效地降低了水的浊度等指标。The reaction of Cyanide in coking wastewater with Fe2＋and H2O2 was studied under pH=3 and in the presence of Fenton reagent.The cyanide in coking wastewater could be removed by precipitating separation ferric ferrocyanide precipitate.In the process,Fenton reagent played a synergistic and strengthening effect,The removel efficiency of total cyanide was more than 98%,the quantity of total cyanide in effluent was less than 0.1mg/L,and the turbidity of coking wastewater was reduced too.
