摘要
水处理行业中除盐工艺主要有离子交换树脂、电渗析、反渗透、电吸附除盐技术等,而在污水回用工程中实际应用较为广泛的有反渗透和电吸附除盐工艺。阐述几种除盐工艺的特点、适应性并进行分析比较。在确定污水回用工程设计中除盐工艺方案时,不仅要熟知几种现有除盐工艺的技术还必须对所处理水的水质和处理目的做详尽调查,力求所选的工艺经济合理和节能降耗。
The demineralization process in water treatment refers mainly to ion exchange resin,electro-dialysis,reverse osmosis,electro-sorption technologies,etc.,and reverse osmosis and electro-sorption technologies are extensively used in practical wastewater reuse projects.This article analyzes and compares the characteristics and adaptability of these technologies,and offers some help for the selection of demineralization process in wastewater reuse engineering design.
