摘要
循环经济的核心是资源节约和资源高效利用,海水淡化利用体现了循环经济的思想。介绍了河北曹妃甸工业区作为国家级循环经济示范区,在拟建的"引海济京"工程中采取循环经济模式,开展浓盐水综合利用,大大降低了淡水制造成本,避免了潜在环境影响。认为,海水循环利用不仅是未来海水淡化利用的主要方向,也是保障水资源可持续利用的有效途径。
The core of circular economy is resources saving and resources utilization with high efficiency.It is embodied in the seawater desalinization.The Caofeidian Industry Zone in Hebei Province is a state-level circular economy demonstration zone.The large desalinization project diverting desalinized water to Beijing to be built adopt the circular economy mode,i.e.,to carry out comprehensive utilization of thick salt waters.It will greatly reduce the cost of producing fresh water and avoid the potential environmental impact.It is main direction for seawater desalinization in the future and an effective way to ensure the sustainable utilization of water resources.
