【摘要】 海水淡化已成为解决沿海地区淡水供给的重要途径之一,随着我国海水淡化产能的持续增加,有必要研究海水淡化工程产生的浓海水排海对海洋生态环境产生的影响。本文从海水淡化工艺特点出发,论述了海水淡化浓海水排海产生的热污染、高盐度、有机物和营养盐、重金属、酸度、余氯、溶解氧和排水机械卷载效应对海水水质、海洋生物和海洋生态环境产生的影响,并从浓海水排海选址设计和综合利用两个方面提出了预防和减轻其环境影响的措施。更多还原

【Abstract】 Seawater desalination has become one of the important ways to solve the problem of fresh water supply in coastal areas.With the continuous increase of seawater desalination capacity in China,it is necessary to study the impact of concentrated seawater discharged from seawater desalination plant on marine ecological environment. In this paper,the effects of thermal pollution,high salinity,organic matter and nutrients,heavy metals,acidity,residual chlorine,dissolved oxygen and mechanical entrainment effects of seawater desalination on seawater quality,marine organisms and marine ecological environment are analyzed,The measures to prevent and mitigate the environmental impact are put forward from two aspects of design and comprehensive utilization.更多还原
