弱碱性阴离子交换树脂运行残余交换容量的经验公式

Experimental Formulae for Residual Capacity of Weakly Basic Anion Exchange Resin Bed Exhausted

研究测定了各种运行条件下弱碱性阴离子交换树脂的残余交换容量，导出了根据层高、流向、流速、温度、进水酸度和二氧化碳及硫酸浓度等求残余交换容量的经验公式．

The operating capacity of weakly basic anion exchange resin used in water treatment mainly depends on the residual capacity in resin bed exhausted.Data of residual capacity in different operation conditions have been tested.According to hight of bed,flow direction,flowrate,temperature,inflow acidity and the concentrations of CO2 and of H2SO4,the empirical formulae for calculating residual capacity are derived.
