摘要
随着淡水资源的紧缺问题日益严重,海水淡化技术在工程上的应用越来越多。多效蒸馏技术和反渗透技术为两种成熟的海水淡化技术,其经济性也随工程的实际情况不同而不同;对两种技术进行经济技术比较,有助于选择更加合理的工程方案。本文介绍了反渗透工艺和多效蒸馏工艺海水淡化的基本原理,总结了两种工艺的优点和缺点,并结合工程实例,对两种海水淡化工艺进行了技术经济比较,为工程实际在两种工艺的比选中提供了参考。
As the shortage of fresh water getting more and more serious,seawater desalinization is utilized more widely in engineering. muti- effect distillation and reverse osmosis are two mature technologies for seawater desalinization,but the economy of each varies in different projects. A technological and economical comparation between these two technologies is good for proposal selection in practical project. The basic theories of muti- effect distillation and reverse osmosis sea water desalinization process were illustrated,and the advantages and disadvantages of each process were summarized. In addition,technical and economical comparation had been done taking a practical case as an example,which provided a reference during the comparation and choice of the two processes.
