海水淡化后浓海水工厂化制盐浅析

摘要

文章介绍了海水淡化和海盐生产的基本工艺,分析了海水淡化后浓海水制盐的几种方法,指出浓海水滩晒制盐是现阶段解决浓海水排放难题的一条有效途径.利用浓海水为原料进行滩晒制盐,尤其是利用二次反渗透法排出的高浓度海水,对制盐企业的技术进步具有一定的积极作用,同时也具有较好的经济和社会效益.%The production technology of seawater desalination and solar salt was introduced in this paper. The salt production using concentrated seawater after desalination was discussed. The effective solution to discharged concentrated seawater was bringing it to solar salt works. The salt production using concentrated seawater, especially the high concentration seawater discharged from second - level reverse osmosis, will promote the production technology level in solar salt works. It will be profitable and have well social benefit.
