树脂吸附法处理低浓度含氰废水

Study on the Resin Adsorption Treatment of Low Concentration Cyanide Containing Wastewater

介绍了树脂吸附处理低浓度含氰百草枯废水的方法,采用“树脂预处理-树脂吸附-树脂脱附”的工艺,使二次蒸汽冷凝水中的氰根降至0.2 mg/kg以下,回收的氰根套用于百草枯中间体合成工段。

The article introduced the method of resin adsorption treatment of low concentration cyanide containing paraquat wastewater.The cyanide in the secondary steam condensate dropped below 0.2 mg/kg by the process of"resin pretreatment-resin adsorption-resin desorption".And the cyanide desorption fluid was used for the synthesis of paraquat intermediate.
