摘要

At present, in addition to fossil energy and other conventional energy, the application of clean energy resources like wind energy, solar energy and nuclear energy in seawater desalination is rising around the word. It represents the future direction of desalination technology development, meeting the need of a resource-saving and environmentally-friendly society. And the technology has a great prospect of applying in regions in serious shortage of fresh water and energy. This paper concludes the advantages and disadvantages of various schemes by analyzing and comparing seawater desalination technologies of various energy. By analyzing five aspects including technological factor, environmental factor, social factor, economic factor and management factor, this paper proposes an evaluation indicators system of the application of energy technologies in seawater desalination. Evaluate the alternative schemes of the coupling of an island's seawater desalination project and energy technologies by fuzzy comprehensive evaluation based on Analytic Hierarchy Process (AHP) and select the optimal scheme. This method provides scientific evaluation methods for the application of energy technologies in seawater desalination.
