摘要
麦岭水厂和周庄水厂是许昌市两个大型供水水源地,为持续开发利用地表水和地下水资源,避免未来出现水资源枯竭、地下水位持续下降等问题,在现场开展了双环渗水试验、灌溉回渗试验、渗坑注水试验和浅井注水试验。试验证明,研究区包气带土层具有良好的渗透性,农田灌溉水回渗、河渠和坑塘地表水渗漏是补给地下水的主要方式,利用地表水灌溉农田和利用河渠和坑塘等设施蓄集地表水,让地表水渗流补给地下水,是实施人工补给地下水适宜的方式。
Mailing Water Supply Plant and Zhouzhuang Water Supply Plant are two large-scale water supply source areas in Xuchang city. For the persistent development and full use of the surface water and groundwater resource, avoiding the water source＇s exhaustion in the future and the groundwater level dropdown persistently, artificial recharge tests such as double-ring water seepage test, land irrigation test, sink water injection test and shallow well water injection test were carried out. These tests proved that vadose soil has good permeability in the research area. And the farm＇s irrigation return seepage permeability, surface water seepage of the channels and pits were the main recharge ways of groundwater. Using surface water to irrigate the farm, reducing the well irrigation area or using channels and pits to store up surface water, allow surface water seepage to recharge groundwater, which is the best way to carry out artificial recharge groundwater.
