前言 ? 随着环保法规的日益严格、用水品质要求提高和水源匮乏加剧,世界各地的电厂、半导体微电子厂、化工、冶金企业正重新评估他们的超纯水处理设备,EDI作为无需化学品的一种经济实用的环保型先进超纯水处理技术,正在逐步取代混床,这正在为全球超纯水处理带来一场革命.?北京水处理设备,北京EDI超纯水设备,北京纯水设备,北京工业超纯水设备, ?? E-CellTMEDI技术能够将二氧化硅和矿物质含量降至1ppb以下,能够将电阻率提高到16Mohm?cm以上,满足了高压及超高压锅炉、精细化工和电子行业对于超纯水的需要.同时E-CellTM EDI大大减少了水处理系统的维护成本,提高了生产效率,延长了设备的生命周期,并将生产现场的危险降至最低. 2. EDI is introduced EDI is in English, Chinese Electrodeionization abbreviation of whole called "continuous electricity to ion technique", its main replacement for traditional mixed bed technology. Ultra pure water production during the past two decades, the cost, environment and the quality factors such as drive, the water supply system has undergone many changes, in particular, exist at present a clear direction, is to reduce the dependence of ion exchange process, so as to reduce the use of chemicals, and improve produce a water yield. I have a very important fact may account for this trend - reverse osmosis as Yin and Yang of the bed alternative technologies is popular. Reverse osmosis desalting as effective technologies, the desalination rate can reach

95 ~ 99%. However, the effect of ion RO place has certain limit, generally speaking, produce water conductivity 0.5 cm (2 atus/MOhm - cm) is its desalting limits. 2.EDI介绍 EDI是英文Electrodeionization的缩写,中文全称为"连续电去离子技术",其主要用于替代传统混床技术. 超纯水的生产在过去的二十年间,在成本、环境及品质等因素的驱动下,其供水系统发生了许多变化,特别值得一提的事,目前存在一个明确的方向,就是减少对离子交换工艺的依赖性,以便尽可能减少化学药品的使用,并提高产水量.有一项重要的事实可以说明该趋势―反渗透作为阴阳床的替代技术正在普及. 反渗透作为有效的脱盐技术,其脱盐率可以达到95~99%.但是,RO对离子的去处效果有一定的限度,一般来说,产水电导率0.5us/cm(2 MOhm-cm)是其脱盐的极限. 当产水水质有更高的要求的时候,就需要采用混床或等同技术. EDI能高效去除残余离子和离子态杂质, 尤其当用户产水水质要求高,比如对电阻率(>10 或者16MOhm-cm), 二氧化硅(
