新疆再生水补给地下含水层的可行性探讨——以乌鲁木齐市为例

Feasibility Study on Managed Aquifer Recharge with Reclaimed Water in Xinjiang: A Case Study of Urumqi

  • 摘要: 利用再生水补给地下含水层是再生水利用的前沿领域,在干旱缺水的新疆开展再生水补给地下含水层,是缓解水资源紧缺、地下水超采、水重复利用率低及水污染严重等问题的有效途径。以乌鲁木齐市为例,通过分析城市水资源供需、再生水利用及水环境现状,考虑地下含水层空间条件及工程场地条件,对干旱区城市再生水补给地下含水层的优势和可行性进行探讨,并针对干旱区特殊的自然地理条件,提出了开展该项工作需要研究的重点问题。建议在新疆干旱区尽早开展再生水补给地下水的研究与实践工作,以促进城市再生水的安全利用,提早获得环境、经济和社会效益。

     

    Abstract: Managed aquifer recharge (MAR) with reclaimed water, a frontier field of recycled water utilization, is an effective way to solve the problems of water scarcity, groundwater overexploitation, low reutilization rate of water and serious water pollution. With case study in Urumqi City, the advantages and feasibility of MAR with reclaimed water in arid-area cities were discussed based on an analysis of the status of water supply and demand, wastewater reuse and water environment, as well as of the conditions of aquifer space and engineering site. Some key issues required to research on MAR with reclaimed water were put forward, aiming at the special geographical and climatic characteristics of arid areas. It was proposed that researches and practices on MAR with reclaimed water should be engaged in Xinjiang so as to promote safe utilization of reclaimed water and gain more environmental, economic and social benefits.
