摘要
为全面分析和比较不同技术海水淡化系统的投入产出,应用能值分析方法,开展反渗透、低温多效、多级闪蒸海水淡化系统的能流分析及能值计算,并进行可持续发展评价。研究结果显示,能源消耗是海水淡化系统最主要的能流输入,反渗透海水淡化系统产品水的太阳能值转换率最低,能值产出率(εEYR)最高,环境负载率(εELR)最低,能值可持续性指标(εESI)最高,因此从能值分析和可持续发展角度,建议新建海水淡化项目优先采用反渗透海水淡化技术。
In order to comprehensively analyze and compare the input and output of seawater desalination systems with different technologies,the energy theory is used to perform energy system analysis,energy calculation and sustainable assessment of RO,MED and MSF desalination systems.The results show that the energy consumption is the most principal energy input.For the RO seawater desalination system,the product transformity is the lowest,the energy yield ratio(εEYR)is the highest,the environment load ratio(εELR)is the lowest and the energy sustainable index(εESI)is the highest.From the viewpoint of energy analysis and sustainable development,it is suggested that new seawater desalination projects should prefer to apply RO technology.
