摘要
试验采用不同的固化剂对锌冶炼产生的废渣进行固化/稳定化技术处理。结果表明:以加入石灰和水泥作为固化/稳定化剂的方案使用试剂最少,处理效果最好,经过固化/稳定化处理的废渣浸出液中的重金属浓度可得到有效控制。经处理后的废渣可进行安全填埋。
The treatment of the solidification/stabilization technique for the slag produced by zinc smelting is carried out with different curing agents.The result shows that the best way is to add lime and cement as solidification/stabilization agent for the use of the reagent is the least,the treatment effect is the best.The concentration of the heavy metal in the waste slag leachate treated by the solidification/stabilization can be effectively controlled.After processing the safe landfill of waste slag can be carried out.
