石灰岩溶地区脱盐水制备流程选择

Selection of Process Flow for Preparation of Demineralized Water in Limestone Karst Regions

我国南方岩溶地区的地下水具有Na+,K+,Cl-,SO42-含量低,浊度、细菌含量高的特点,在制备ρ(SiO2)<0.1mg/L,电导率(25℃)<5μS/cm的低品位脱盐水时,作者建议了三种典型的工艺流程,可供在岩溶地区设计固定床型制取脱盐水装置时参考。

The ground water in the karst regions in South China features low contents of Na+,K+,Cl-and SO42 and high turbidity and bacteria content.The author has proposed three typical processes for the preparation of low grade demineralized water of ρ(SiO2) < 0.1 mg/L and conductivity(at 25 ℃)< 5 μS/cm,which can be used for reference in designing fixed bed demineralized water facilities in the said regions.
