摘要:

回顾了目前常用的海水淡化技术及其应用现状,重点综述了海水淡化浓盐水排放对海洋环境的影响,分析了排放盐水的组分、盐度、热污染、腐蚀产物、化学清洗剂等对海洋环境和海洋生物的潜在影响,提出了相应的解决措施与解决方法,说明浓盐水零排放技术是解决环境问题的有效途径。

Abstract:

The principles and methods of seawater desalination and water treatment as well as their application progress are presented. The impact of discharged concentrated brine from seawater desalination plant is highlighted. The discharge can lead to substantial increase in salinity and temperatureand accumulation of metalshydrocarbons and toxic anti-fouling compounds in receiving waters. The potential impacts of the concentrated brine compositionsalinityheat contaminationcorrosion products and chemical additives are summarized. Measures to avoid adverse effects are also discussed. Zero liquid dischargeZLDis an effective way for sustainable seawater desalination.
