引言在高纯水制备系统中,反渗透装置以其优良稳定的除盐性能,简单方便的操作管理,而被大量地用于前级处理部分。这种以过滤——反渗透作为前级水处理部分,以离子交换——精处理为后级水处理部分的工艺流程,是当今国际上典型的工艺设计。在我国,由于这两年电子工业的迅猛发展。先后从一些比较发达的国家和地区引 INTRODUCTION In high purity water production systems, reverse osmosis units are used extensively in the pre-treatment section due to their excellent and stable desalination performance, simple and convenient operation and management. This type of process, which is based on filtration—reverse osmosis as the former water treatment part and ion exchange—precision treatment as the latter water treatment part, is a typical international process design. In our country, due to the rapid development of the electronics industry in these two years. It has been cited from some relatively developed countries and regions.
