淡化海水的矿化方法浅析

Brief Analysis on Methods of Mineralization for Desalinated Seawater

淡化海水可补充淡水资源,具有广阔的应用前景,但淡化海水中盐分很少,缺乏人体必需的Ca^(2+)和Mg^(2+),且水质不稳定,会对现有城市供水管道造成腐蚀。分析后处理矿化过程的需要,对比总结添加药剂法、掺混法和溶解矿石法几种矿化方法,并对未来的矿化研究提出要求。

Desalination of seawater can be used for replenishing of fresh water resources and it has broad application prospects.However,the desalinated seawater has very little salt,lacks the essential Ca^(2+)and Mg^(2+),and the water quality is unstable,existing urban water supply distribution network will be corroded by desalinated seawater.The needs of post-processing mineralization processes were analyzed,several remineralization methods,such as chemical dosing,blending and mixing,and ore dissolving were compared and summarized,put forward requirements for future remineralization studies.
