摘要
研究了用硫酸亚铁新工艺有效降低高浓度含氰废水中氰含量的方法，使氰化物净化率＞９９．９９％。对工艺过程中的废渣进行了回收，制备出副产品黄血盐钠，其质量达到国家标准，消除了二次污染，提高了经济效益。
The method of efficient reduction high concentration cyanide-containing waste water with ferrous sulfate new technology was studied.The purificatory rate is greater than 99.99%. Waste residue in treatment processis recovered and sodium ferrocyanide is prepared. The quality of production comes up to state standard.The technology removes the second pollution and increases economical benefit.
