摘要
为研究京津冀沿海地区海水淡化取水适宜性,于2016年对京津冀沿海地区的海水淡化项目和海洋地质环境进行详细调查,并对我国海洋取水现状进行综合研究。通过综合研究发现:从海洋自然属性角度出发,沧州和天津沿海地区属于淤泥质海滩,水浅坡缓、深水区离岸远、风浪作用下水体中泥沙含量高,适合开发大型(>10万m3/d)海水淡化工程,取水方式适宜在海上建设沉淀池、采用潮汐式取水;唐山大清河口以西唐山沿海近岸海域属于淤泥质海滩,深水区离岸较远、水体中泥沙含量较高,适合开发大型(>10万m3/d)海水淡化工程;大清河口以东唐山和秦皇岛近岸海域大部分属于砂质岸滩,深水区离岸较近、水质较好,适宜各种规模的淡化工程,且取水方式可采取开挖埋管道的形式采集深水区的海水;沿海海港码头工程岸段由于水深条件较好,适合建设各种规模的淡化项目。
In order to study the suitability of desalinated water intake in coastal areas of Beijing,Tianjin Hebei region,detailed investigation was carried out on the desalination project and marine geological environment in coastal areas of Beijing,Tianjin Hebei,current situation of sea water utilization of our country was also comprehensive researched.The results showed that：from the perspective of marine natural property,coastal area in Cangzhou and Tianjin is muddy beach,the water is shallow and slope slow,deep waters are far offshore,the sediment concentration is high in the water body under the action of wind and waves,which is suitable for the development of large（〉100 000m^3/d）desalination project and construction of settling ponds,by the tidal water.Coastal inshore areas on the west of Daqing river estuary of Tangshan belong to the muddybeach,sediment in deep waters is far offshore,the water content is higher,which is suitable for the development of large（〉100 000m^3/d）desalination project.Most of the nearshore on the east of Daqing river belong to sandy along seashores,deep waters are close to shore and the water quality is good,which is suitable for all sizes of desalination project,buried pipeline can be used to gather sea water from the deep sea.The sections of coastal port engineering is suitable for project construction of all sizes,due to the good deep water conditions.
