针对超滤过程中的两种操作工艺——间歇分批操作和连续操作对小分子的不同分离程度进行对比说明，认为在小分子浓度较大情况下达到同样洗滤程度时，连续操作所耗水量小于间歇操作
In the process of ultrafiltration, two kinds of operation technology-intermittent batch operation and continuous operation-comparison of different degree of separation of small molecules shows that in the case of large concentrations of small molecules to achieve the same degree of filtration when the continuous operation Less water than intermittent operation
