摘　　要：浓海水中含有丰富的化学资源,对浓海水进行处理与处置,不仅可以进一步提高水收率,还可以实现对浓海水中化学资源的有效利用。文中分析了浓海水排放后盐分、化学物质、重金属及温度对海洋生态的影响;介绍了共晶冷冻结晶、多效蒸馏、膜蒸馏、电渗析、正渗透五种浓海水处理技术的原理及特点,列举了部分国内外研究进展以及实际工程案例,并对多种工艺的特点进行了比较;最后指出浓海水处理与综合利用集成技术将成为浓海水处理发展的新方向。Concentrated seawater contains rich chemical resources. Concentrated seawater treatment and disposal can not only further increase water recovery rate, but also can realize effective use of chemistry resources contained in concentrated seawater. Firstly, the article analyzed the influence of salt, chemicals, heavy metals and temperature on the marine ecosystem during concentrated seawater discharging. Secondly, the article introduced the principles and characteristics of some concentrated seawater treatment technology, including the eutectic freeze crystallization, multi-effect distillation, membrane distillation, electrodialysis and forward osmosis. In addition, the paper also introduced the researched progress and some actual project cases of domestic and overseas. Characteristics of several technologies were compared too. The study shows that the integrated technology of concentrated seawater treatment and comprehensive utilization will become the new direction of development of concentrated seawater treatment.
