絮凝沉淀—SO_2/Air法处理含氰废水的试验

Research on cyanide-containing waste water treatment with coagulative sedimentation-SO_2/Air method

阐述了絮凝沉淀—SO2/Air法有效处理废水中总氰的原理,并对其去除总氰的影响因素进行了大量试验。试验结果表明,在合理控制pH值、氧化时间和药品投加量等条件后,可使废水中总氰的去除率达到99.8%,从而有效解决了氰化工艺废水中总氰(简单氰化物和络合氰化物)的去除问题,实现了含氰废水的达标排放。

The theory of coagulative sedimentation-SO 2 /Air method for cyanide-containing waste water treatment is discussed.Numerous experiments are carried out on the influencial factors of cyanide removement.It is showed that the removement rate of cyanide can reach 99.8%by controlling pH,oxidization time and reagent dosage.And the total cyanide in waste water is removed efficiently by this technology,which can meet the national discharge standard.
