摘要

沙特阿拉伯王国境内的淡水资源是一种稀有和珍贵的商品,必须在综合水管理的范围内加以管理。在沙特王国,瓦底含水层含有很高比例的天然新鲜地下水。这种资源目前被过度使用,在许多地方已经枯竭或受到污染。一种可用于恢复或增强瓦底含水层内淡水资源的资源是经过处理的城市废水(再生水)。每年,全国大约80%经过处理的城市废水被排放为废物,没有任何有益的利用。这些排放不仅代表着水资源的损失,而且还造成了许多不利的环境影响,例如对敏感的近岸海洋环境的破坏和高盐度的内部地表水区域的产生。一项对沙特阿拉伯瓦迪含水层水文地质的调查显示,这些含水层可用于开发含水层补给和恢复(ARR)系统,该系统将能够处理水质受损的水,将其储存到需要的地方,并允许回收水以输送到需要的地区。全面设计的ARR系统可以在wadi含水层系统中设计高容量,可以与wadi的自然作用相一致,同时提供额外处理,储存和回收再生水的所需功能,同时减少开发额外的能源密集型海水淡化以满足新的供水需求。

Restoration of wadi aquifers by artificial recharge with treated waste water.

Fresh water resources within the Kingdom of Saudi Arabia are a rare and precious commodity that must be managed within a context of integrated water management. Wadi aquifers contain a high percentage of the naturally occurring fresh groundwater in the Kingdom. This resource is currently overused and has become depleted or contaminated at many locations. One resource that could be used to restore or enhance the fresh water resources within wadi aquifers is treated municipal waste water (reclaimed water). Each year about 80 percent of the country's treated municipal waste water is discharged to waste without any beneficial use. These discharges not only represent a lost water resource, but also create a number of adverse environmental impacts, such as damage to sensitive nearshore marine environments and creation of high-salinity interior surface water areas. An investigation of the hydrogeology of wadi aquifers in Saudi Arabia revealed that these aquifers can be used to develop aquifer recharge and recovery (ARR) systems that will be able to treat the impaired-quality water, store it until needed, and allow recovery of the water for transmittal to areas in demand. Full-engineered ARR systems can be designed at high capacities within wadi aquifer systems that can operate in concert with the natural role of wadis, while providing the required functions of additional treatment, storage and recovery of reclaimed water, while reducing the need to develop additional, energy-intensive desalination to meet new water supply demands.
