Evaluation Index and Selection System of Seawater Desalination Site Selection in Hebei Province
Pages: 66-70
Year: Issue:  6
Journal: Ocean Development and Management

Abstract: In order to establish the seawater desalination system in Hebei Province,a survey of coastal desalination projects was conducted in 2016,establishing a seawater desalination system based on the comprehensive analysis of marine natural environment and seawater desalination technology in Hebei Province.It was found that the evaluation indexes of seawater desalination can be divided into three aspects:economy,water quality and water quantity.Among them,water quality indicators need to be evaluated according to desalination process.The results showed that the water depth and the type of sediment are the key factors in the selection of water resource of seawater desalination.The offshore distance of the water source directly affects the capital invest-ment of the project construction.General evaluation of desalination water source selection includes the following steps:compliance analysis on land use and marine function zoning;analysis on the distance to offshore water;evaluation of the water depth and ocean bottom sediment types;analy-sis on water quality;and the desalination water suitability assessment.The evaluation system could provide technical reference for the development and utilization of seawater desalination in water sources of Hebei Province.
