摘　　要：海水淡化或工业生产过程中会产生大量的浓盐水。浓盐水的大量排放不仅造成了局部海水温度和盐度升高,还造成了局部水体富营养化,给海洋生物和生态环境造成了巨大的危害。对浓盐水进行综合处理,实现盐和水资源的高效综合利用,对于降低浓盐水排放的环境污染具有重大社会意义和经济意义。本文综述了主要的浓盐水零排放工艺与技术的研究进展,并且结合典型过程工业废水处理分析了国内外盐水零排放技术的特点和发展趋势。盐水零排放技术主要有蒸发塘技术、膜-蒸发结晶技术和多效蒸发-蒸发结晶技术,以及在3种技术基础上发展的多技术耦合模式。It is a crucial issue worldwide of environmental pollution resulted from the huge amount of brine from the seawater desalination and industrial processes. The increased local seawater temperature, salinity and water eutrophication have remarkably negative impact on the marine life and ecological environment. Using brine management system of zero liquid discharge, desalination of brines, salt and other chemical compounds recovery from brines are the most effective adopted currently. This paper briefly reviewed the recent advances in the technologies available of zero liquid discharge approaches. The main zero liquid discharge approaches include evaporation pond, membrane technology, multi-effect evaporation - evaporation crystallization technology and the integrated processes based on the above three technologies.
