摘要
以六支膜单段串联反渗透系统为研究对象,总结了膜污染对膜元件性能影响的主要特征,并结合膜污染的实际特点,分析了膜元件污染对反渗透系统运行性能参数的影响,分别指出了膜压降、膜通量、脱盐率3项元件性能指标变化对反渗透膜系统性能指标的作用,为相关实际工程问题的解决提供了一定的参考依据.
Taking RO system of the series of six-element in one stage as the target of the research, main characteristics of the effect of the membrane fouling on the membrane element capability are summarized. And combining with the practical characteristics of the membran fouling, influence of membrane element fouling on performance parameters of the reverse osmosis （RO） membrane system is studied. The effect of changing the capability indexes on the reverse osmosis system performannce index is pointed out. This study provides a reference frame for resolving some relational engineering problems.
