某县城渗流井取水工程设计

Water intake design of seepage wells for a county

通过对某县水源地进行物探和水文地质勘察,经方案比较,采取渗流井工艺取水。该工艺通过大量集取地下水,激发地表水的补给,增加了取水量;与渗渠相比,不仅在冬季结冰期能持续供水,还改善了水质;与地表水厂相比,免除了复杂的水处理设施,降低了运行费用。

The geophysical prospecting and geo-hydrologic reconnaissance have been done in the water resource region of a county and seepage well is chosen on the basis of comparison. It is believed that the underground water will soon be recharged by the induction of considerable abstract of the seepage wells to guarantee the water supply. Compared with infiltration channel, the seepage well can abstract water all the year around even in winter and also the water quality is better. On the other hand, no complicated water purification facilities are used, which are necessary for surface waterworks, so both the investment and operating expenses will be cut down.
