弱碱性阴离子交换树脂用于水处理时，其主要性能指标———工作交换容量，主要取决于失效树脂层中残余交换容量的大小。此项研究在实验室条件下，通过３４ｍｍ直径离子交换柱模拟运行试验，测定了Ｄ３０１Ⅲ型弱碱树脂在不同运行条件下的残余交换容量，并以此为基础，导出了该树脂运行残余交换容量与粒度、层高、温度、水流速、流向、进水酸度及硫酸含量、失效酸度、再生剂量和流向等影响因素关系的经验公式。这为预言该树脂在具体应用条件下的工作交换容量和平均出水酸度奠定了基础。
Weak base anion exchange resin used for water treatment, the main performance indicators --- work exchange capacity, mainly depends on the size of the residual resin layer of the exchange capacity. The study under the laboratory conditions, through the 34mm diameter ion exchange column simulation run test D301 Ⅲ type weak base resin in different operating conditions, the residual exchange capacity, and on this basis, derived the resin residue Exchange capacity and granularity, layer height, temperature, water flow rate, flow direction, water acidity and sulfuric acid content, the failure of acidity, regeneration dose and flow direction and other influencing factors of empirical formula. This laid the foundation for predicting the exchange capacity and average effluent acidity of the resin under specific application conditions.
