高硬度矿泉水的软化研究

Research on Softening of High-hardness Mineral Water

采用加药沉淀———离子交换法 ,结合实例对高硬度矿泉水进行软化研究。试验结果和工艺计算表明 :加药沉淀—离子交换法对高硬度矿泉水具有良好的软化效果、方法简单、投资少、成本低、水质好等优点 ,是一种既能降低矿泉水的硬度和碱度 ,又能保持水中微量元素含量的理想方法。

Based on the principle of chemical precipitation+ion-exchange,study on the softening of high-hardness mineral water is carried out in a practical case.From the testing results and technical calculation,it is shown that such a type of process has good softening results for high-hardness mineral water with such advantages as simple,low investment and good water quality.It is a type of ideal method for reducing hardness and alkalinity as well as maintaining trace elements in the water.
