近年海水淡化发展较快,用途也逐渐从工业扩大到市政供水。为确保海水淡化水的安全和对供水管网的保护,在对淡化水的后处理方法进行总结的基础上,从再矿化稳定水质、投加缓蚀剂、管材及管网运行状况三方面详细探讨了淡化水作为城市供水时的水质稳定性研究现状,并提出当前研究中存在的主要问题。 In recent years, the desalination of seawater has developed rapidly, and its use has gradually expanded from industry to municipal water supply. In order to ensure the safety of seawater desalinated water and the protection of water supply network, based on the summary of the desalination water post-treatment methods, from the three aspects of remineralization to stabilize water quality, adding corrosion inhibitor, pipe and pipe network operating conditions The research status of water quality stability of desalinated water as urban water supply is discussed in detail, and the main problems in current research are put forward.
