| 摘 要： | 文章基于2016年对河北省沿海海水淡化项目的调查研究,通过对海洋自然环境现状和海水淡化工艺进行系统综合分析,建立河北省海水淡化水源地选划体系。研究发现,海水淡化水源地选划的评价指标内容可分为3个方面,即水量、水质和经济性。其中水质指标需根据海水淡化工艺进行相应评价。研究表明,水深和底质类型是进行海水淡化水源地选划的关键因素,水源地的离岸距离直接影响项目建设的资金投入。海水淡化水源地选划的大致评价步骤为:对土地利用方式和海洋功能区划进行符合性分析,对水源地离岸距离进行分析,对水深和海洋底质类型进行评价,进行水质分析,最终给出适宜性评价结果。该评价体系可为河北省海水淡化水源地的开发利用提供技术参考。

| Abstract: | In order to establish the seawater desalination system in Hebei Province,a survey of coastal desalination projects was conducted in 2016,establishing a seawater desalination system based on the comprehensive analysis of marine natural environment and seawater desalination technology in Hebei Province.It was found that the evaluation indexes of seawater desalination can be divided into three aspects:economy,water quality and water quantity.Among them,water quality indicators need to be evaluated according to desalination process.The results showed that the water depth and the type of sediment are the key factors in the selection of water resource of seawater desalination.The offshore distance of the water source directly affects the capital investment of the project construction.General evaluation of desalination water source selection includes the following steps:compliance analysis on land use and marine function zoning;analysis on the distance to offshore water;evaluation of the water depth and ocean bottom sediment types;analysis on water quality;and the desalination water suitability assessment.The evaluation system could provide technical reference for the development and utilization of seawater desalination in water sources of Hebei Province. |
