精盐水Ca^(2+)、Mg^(2+)超标原因及处理方法

Causes of over standard on Ca^(2+) and Mg^(2+) in fine brine and its treatment measures

介绍了由于操作、工艺、原材料等因素引起的精盐水Ca2+、Mg2+超标原因,提出了增加凝聚剂,调整过碱量和反应时间,以及稳定沉降温度等处理措施,指出加强控制和分析可预防Ca2+、Mg2+超标。

The causes of over standard on Ca2+ and Mg2+ in fine brine was introduced. And some countermeasures on it was put forward, such as increasing polycoagulant, adjusting excess alkali and reaction time, stabilizing rate of settling, et al. It was pointed that the over standard can be prevented by strengthening the work of control and analysis.
