摘要
采用阶梯排水法为运行模式,探讨了判断反渗透阻垢剂阻碳酸钙垢性能相对优劣的关键指标试验研究。结果表明:采用阶梯排水法可以用于反渗透阻垢剂筛选;pH、ΔK_(Ca)(浓缩倍数增量)和饱和指数(LSI)等都可作为筛选反渗透阻垢剂的关键指标,以ΔK_(Ca)最灵敏。
The key indicators for assessing the relative resistance to calcium carbonate scale of various reverse osmosis inhibitors are discussed based on the drainage gradient method. The results show that the method can screen out the performance of scale inhibitors; pH, ΔK_(Ca)(increase in cycle of concentration) and Langelier's saturation index(LSI) can be used as key indicators and that ΔK_(Ca) is the most appropriate one.
