用多硫化物同时去除高浓度含氰电镀废水中氰和重金属的研究
- SIMULTANEOUS REMOVAL OF CYANIDE AND HEAVY METALS FROM CYANIDE-CONTAINING LIQUOR WITH POLYSULFIDE
- 摘要：研究表明,用多硫化物处理高浓度含氰电镀废水的同时,亦可有效地去除废水中的重金属,其方法操作简便。本文对实际应用中所需的工艺条件、反应产物硫氰化物的去向、残余多硫化物的处理、多硫化物的合成、反应热效应等进行了研究,取得了满意的结果。
- Abstract：Research of the treatment of highly concentrated cyanide-containing liquor with polysulfide has demonstrated that this technique is able to remove effectively cyanide and heavy metal ions from the liquor simultaneously. The method is simple and easy to operate. The topics discussed in the paper are as follows: option of technological conditions, the fate of thiocyanate formed during the reaction, the removal of remained polysulfide in reaction liquor, manufacture of calcium polysulfide and reaction heat etc.
