海水淡化厂浓盐水排海监测分析

Monitoring and Analysis of Concentrated Brine Discharge from Seawater Desalination Plant

随着淡水资源紧缺和海水淡化处理成本的下降,海水淡化厂数量快速增加,大量浓盐水进入海区会导致受纳海域盐度升高。高浓度盐水给海洋生态环境带来许多负面影响,有关浓盐水的海洋生态安全问题备受人们关注。文章就青岛市董家口港海水淡化浓盐水排放对海洋环境造成的潜在影响进行监测分析,结果显示浓盐水排放仅会对排放口周边极小范围产生影响(200 m以内),且未对琅琊湾周围海域海洋生物造成较大环境风险,表明董家口海水淡化厂浓盐水排放对环境影响较小。

With the shortage of freshwater resources and the decrease in the cost of seawater desalination treatment,the number of seawater desalination plants is rapidly increasing.A large amount of concentrated saline water entering the sea area will lead to an increase in salinity in the receiving sea area.High concentration saline water has brought many negative impacts on the ma-rine ecological environment,and the issue of marine ecological security related to concentrated sa-line water has attracted people's attention.The article monitored and analyzed the potential impact of concentrated brine discharge from Dongjiakou Port in Qingdao on the marine environment.The results showed that concentrated brine discharge will only have an impact on a very small area around the discharge outlet(within 200 m),and will not cause significant environmental risks to marine organisms in the surrounding waters of Langya Bay.It indicated that the concentrated brine discharge from Dongjiakou seawater desalination plant has a relatively small impact on the environment.
