碱废液与付产高低温盐的综合利用

The Comprehensive Utilization of Ca-contained Waste Water and High-low temperature Salts

本研究介绍利用氯碱厂排弃的含钙废液、及盐化工付产的高低温盐二者定量匹配，通过保温沉降，离心分离，蒸发浓缩等手段，最终达到生产白色氯化镁，精制盐，硫酸钙及利用硫酸钙与氯化钾转化生产硫酸钾的工艺。

A technology which the Ca-contained waste water from ammonia-abkali factory and the high-low temperature salts-by products from salt factory were used to produce white MgCl2,fine salt and CaSO4 was introduced in this paper. And then,the route to make K2SO4 from CaSO4and KCl was shown.
