优化工艺指标提高盐水质量

介绍了通过优化工艺指标，如精确控制化盐温度、增加粗盐水的过碱量、减少助沉剂的投加量等提高了盐水质量并降低了生产成本。

Optimizing process index to raise brine quality

Through optimizing process index, the brine quality was raised, as well as the production cost was reduced. Some improvement measures was taken, such as accurately controlling the temperature of salt dissolving, increasing the excessive alkali contents in primary brine, reducing the precipitating agent contents, et al.
