摘要
基于生命周期评价理论,对水足迹评价方法进行了研究,提出了一种适用于海水淡化系统的水足迹核算方法。以日产万吨级以上的某大型反渗透海水淡化系统为例,采用本方法对该淡化系统的水足迹进行核算,计算结果为1.52×10^(-2) m^(3)/m^(3)产品水。本研究为水足迹评价理论在海水淡化领域的应用提供了参考。
Water footprint assessment method was studied in this paper,and an accounting method of water footprint was proposed for the typical seawater desalination system based on the life cycle assessment theory.A large-scale reverse osmosis seawater desalination system as an example,the system daily output was more than 10,000 tons,the water footprint of this desalination system was calculated.The water scarcity footprint was 1.52×10^(-2) m^(3)/m^(3) product water.This study would provide a reference for the application of water footprint evaluation theory in the field of seawater desalination.
