Abstract

A process for treating the high content of sulfuric acid radicals in saline includes such steps as firstly mixing halogen solution, barium carbonate and promoter and compounding into a thick liquid, then activating the compounded thick liquid by grindnig, chemical reaction on the said saline at 60-70 deg.C while stirring and cylically activating deposit for 40-60 min, and adding sodium hydroxide.Its advantages are simple process, low cost, and high utilziation rate of barium carbonate (98%).
本发明公开了一种用碳酸钡处理盐水中高含量硫酸根的方法,其步骤是,首先将卤水与碳酸钡和促进剂配制成浆,其配比为碳酸钡加入促进剂,盐水=1∶5-10;其次是将配比浆液经研磨机活化,立即投入已升温60-70℃含有硫酸根盐水进行化学反应;第三是将含有硫酸根的盐水温度控制在60-70℃,不断搅拌反应,并将沉淀物不断地循环活化,使碳酸钡和促进剂的混合物能与盐水中的硫酸盐、钙及镁离子完成化学反应,反应时间40-60分钟;第四是在盐水中加入烧碱。本发明工艺简便,方法易行,成本低,碳酸钡利用率高达98%以上,经济效益显著。
