在高离子强度条件下，测定了钠基蒙脱石沉积物与上层清液界面沉降速率与固体体积分数的关系。采用Michaels和Bolger方法对试验结果进行分析，阐明了絮凝泥沙的沉降速度（Q1）、絮凝体代表粒径（d1）和有效体积分数增加率（a）等物理指标。通过与直接测定的Qf和df值的比较，证实了该方法对钠基蒙脱石的适用性。钠基蒙脱石絮体比高岭石等材料的絮体具有更好的保水性能。
The settling rate of the interface between sodium montmorillonite sediment and supernatant liquid was measured under a condition of high ionic strength as a function of solid volume fraction. The results were analyzed using the method of Michaels and Bolger to elucidate the physical indexes of flocculated sediment such as the settling velocity (Q,), the representative diameter (d1), and the increase ratio of effective volume fraction (a) of floc. The applicability of this method to sodium montmorillonite was confirmed bycomparing the Qf and df values obtained from this method with those from the direct measurement previously reported. The floc of sodium montmorillonite retains more water compared with that of kaolinite and other materials.
