摘要
微咸水淡化是解决水资源短缺、提高水资源供给保障能力的可行途径。我国微咸水资源蕴藏丰富且主要集中在淡水资源短缺的西北和华北地区,总量约200亿m3,具有重要淡化利用价值。在综述国内微咸水脱盐及淡化利用领域的技术优缺点、应用范围及相关经验的基础上,从脱盐技术特征、能源供给、数值模拟辅助工艺优化、数字管理等方面进行总结国外先进微咸水淡化处理工艺,并提出我国微咸水资源化利用技术对策及发展方向。
Desalination is the reasonable and reliable approach for solving water resource shortage and improving freshwater support capacity.China has almost 20 billion m3 of brackish water resources but the majority of this resource are located in the north and northwest areas where subject seriously freshwater shortage.After reviewing the technical merits and shortcomings,application scope and experiences for different brackish water utilization and desalination at home,from the aspects of character of desalination technology,energy supply,numerical simulation assisted technique optimization and digital management,the paper analyzed and summarized the foreign techniques for brackish water desalination,and Finally proposed technical countermeasures and deveopment direction for utilizing valuable brackish groundwater at a more efficient level.
