氰化钠法制备三聚氯氰废水的处理与回用技术研究

Research on the Treatment and Recycling Technique of Wastewater from the Sodium Cyanide Process Cyanuric Chloride Production

采用四效蒸发、A/O工艺处理与RO工艺处理后,对某企业氰化钠工艺三聚氯氰废水进行深度处理,去除COD和盐分。处理结果表明:经过组合工艺处理后,出水水质满足回用水标准,可以实现废水回用。

The process of four -effect evaporator,Anoxic/Oxic bioreactor and RO process has been used to remove COD and salt, for the advanced treatment of wastewater from the Sodium cyanide process Cyanuric chloride production. The resalt show that the effluent water which treated by combined process, can be reused.
