摘要
介绍氰化钠装置废水采用加热分解——次氯酸钠氧化法废水预处理技术,并通过对影响废水处理效果几个因素的论述及简单经济比较,说明了上述处理不失为高浓度含氰废水除氰工艺一种有效方法。
The method for preliminary treatment of wastewater containing cyanides coming from NaCN unit is described in this paper.The treatment is accomplished by thermal decomposition-sodium hypochlorite oxidation.Several factors affecting the efficiency of treatment are discussed.Practice shows that this method has advantages of simple process flow diagram and adaptable to different sources of cyanides containing wastewaters.So it can be considered as an effective method for this purpose.
