反渗透系统的性能变化分析及量化评价方法

如何对反渗透系统运行的综合性能进行评价，在实践中往往由于影响的因素多种多样，而且环境条件也发生变化，掌握运用其实并不是容易的．针对具体工程情况，在参考有关文献的基础上，提出了运行指标归一化处理的概念和计算方法．实践证明：这种方法是一反渗透系统进行更加科学管理的手段和量化方法．并还对反渗透系统运行中产水量和脱盐性能的变化进行了分析，列举了可能的各种原因；对影响膜组件的污染因素进行了说明，并提出膜组件污染现象和清洗方法．

Analysis and estimation for the run of RO system

The evaluation of the general efficiency of RO system is not easy, because there are many effecting factors, especially under different environmental conditions. By referring to some references. This paper provides a concept of normalization, and a calculation method to deal with the data. The paper analyses the reasons of the degressive performance of RO equipment, and explain the reasons of fouling of RO filter, meantime list the phenomenons of the fouled filter and proposes a conditions of cleaning method.
