海水淡化浓海水零排放技术研究

摘要

Comprehensive utilization of concentrated seawater is not only environmental friendly,but also helpful in the recovery of resources such as freshwater,salt,bromine,potassium chloride,epsomite,bischofite and etc. Compared to salt production from seawater,the comprehensive utilization of concentrated seawater greatly reduces investment and energy consumption. In the paper,technologies of zero discharge of concentrated seawater were in-troduced and both their advantages and disadvantages were analyzed. In the end,a new technical route was put for-ward to realize the real industrialized zero discharge for seawater desalination.%浓海水综合利用不仅可以保护环境，而且可以回收资源，如淡水、盐、溴、氯化钾、泻利盐以及水氯镁石等。与海水制盐相比，浓海水综合利用能够大幅降低投资和能源消耗。详细介绍了浓海水零排放技术，对目前浓海水零排放技术优缺点进行了分析，并提出了新的技术路线以真正实现工业化海水淡化浓海水零排放。
