摘要
淡化海水是重要的淡水补充水,其水质好,但pH、碱度、硬度都很低。这种特质的水极具侵蚀性,若不加处理直接纳入城市供水系统会造成管网的腐蚀。因此,本文从管道优选、管材防腐和淡化水厂后处理(投加药剂法、溶解矿石法、掺混法、添加镁法)等3个方面,系统地介绍了目前淡化海水风险防控技术的原理、适用条件和发展现状,可为今后实现淡化海水的规模化应用提供参考。
Desalination seawater is an important source for supplementing fresh water,its water quality is high,but the pH,alkalinity and hardness of desalination seawater are very low.Desalination seawater is corrosive due to these characteristics,which will cause damage to the pipe network if it directly brought into the urban water supply system without treatment.Therefore,this review systematically introduce the desalination of risk prevention and control technology principle,applicable conditions and development present situation from the three aspects of the pipe selection,pipe anticorrosion and desalination plant post-processing method(additive agent,dissolving ore,blending,adding magnesium method).This review can provide useful reference for the large-scale application of the desalination in the future.
