摘　　要：文章主要阐述通过优化卤水净化配药方法,解决卤水精制过程中混卤Ca^(2+)、Mg^(2+)、SO_(4)^(2-)含量不稳定、波动大、加药带入大量淡水导致的精制卤水氯化钠含量低等问题。通过优化卤水净化工艺,在综合利用盐湖尾矿、贫矿资源的同时,实现不同种类、不同品位的盐矿资源生产满足纯碱、金属钠盐质量要求的液体盐。This article mainly elaborates the optimization of unstable and fluctuating mixed Ca~(2+),Mg~(2+),SO_4~(2-)content and low NaCl content in refined brine caused by changing the existing brine purification and dosing methods during the brine refining process.By optimizing the brine purification process,while comprehensively utilizing salt lake tailings and lean mineral resources,different types and grades of salt mineral resources can be used to produce liquid salts that meet the quality requirements of soda ash and metal sodium salts.
