深层地下水SPD人工补给系统

提出了一种新的深层地下水回灌方法———SPD人工补给系统,并通过室内沙槽模拟试验,对该系统和 常规的直接井回灌法作了比较。研究表明,利用该系统补给深层地下水,具有回灌水质要求低、补给速度快、补 给量多、不易淤堵等特点,是深层地下水人工补给的一条有效的新途径。

SPD Artificial Recharge System of Deep Groundwater

The method of recharge groundwater by deep well is used widely. Because the well is adapt to be clogged, this method usually has high requirement for water quality. This made the efficiency of the recharge be- ing low, and corresponding cost increased greatly. A new method, SPD artificial recharge system, is put for- ward. Through simulation experiment in lab, the new method is compared with direct well recharge. Study showed that the new method is an effective way to recharge deep groundwater. It has the advantage of low re- quirement for water quality, high speed of recharging, larger amount of recharge and anti-clogging etc.
