摘要在比利时科克西德附近的深层含水层中测试了含水层储存和恢复（ASR）的可行性。为了实现这一目标，将含氧饮用水注入含有缺氧微咸水的深层含水层（蒂嫩地层）。含水层的水力特性，确定了使用一个步骤下降测试。通过两次推拉试验研究了注入水引起的化学过程。通过反数值模型解释了阶跃压降试验，得到了3.38 m2/d的渗透率和0.00038 d2/m5的井损系数。推拉试验确定注入水和原始沃茨之间的混合以及阳离子交换是确定回收水质量的主要过程。DOC的动员，好氧呼吸，反硝化和磷酸盐的动员也观察到。
Abstract The feasibility of aquifer storage and recovery (ASR) was tested in a deep aquifer near Koksijde, Belgium. To achieve this, oxic drinking water was injected into a deep aquifer (the Tienen Formation) that contains anoxic brackish water. The hydraulic properties of the aquifer were determined using a step-drawdown test. Chemical processes caused by the injection of the water were studied by two push—pull tests. The step-drawdown test was interpreted by means of an inverse numerical model, resulting in a transmissivity of 3.38 m2/d and a well loss coefficient of 0.00038 d2/m5. The push—pull tests identified mixing between the injection and pristine waters, and cation exchange, as the major processes determining the quality of the recovered water. Mobilization of DOC, aerobic respiration, denitrification and mobilization of phosphate were also observed.
