探索双膜法生产优质盐的途径

摘要

This paper propose transformation ideas for the first and second production line, explores reduce the salt slurry in sulfate and calcium and magnesium impurity content and improve salt product quality of the first and second production line to meet the need for raw materials in the chemical production.%提出第一、二生产线改造思路，探索通过双膜法精制卤水工艺对盐浆进行淘洗，降低盐浆中硫酸根和钙镁杂质含量，提升第一、二生产线成品盐品质，满足大化工生产原料需求。
