Method for repairing groundwater pollution through well digging and closure
The invention discloses a method for repairing underground water pollution through well digging and closure, specifically belonging to the field of water pollution prevention and control. According tothe invention, a plurality of remediation systems are arranged around a pollution source in underground water of a polluted area; each remediation system comprises a main pumping well and an auxiliary pumping well; each auxiliary pumping well is arranged on the side close to the pollution source; and monitoring wells are arranged on the two sides of the auxiliary pumping wells and the sides, awayfrom the auxiliary pumping wells, of the main pumping wells. The method comprises the following specific repairing steps: S1, performing single-well and multi-well water pumping experiments, and determining hydrogeological parameters of surrounding areas of the polluted area; S2, determining an optimal closure area; S3, determining well digging positions and the number of to-be-dug wells; and S4,conducting prevention, control and remediation of groundwater pollution in the polluted area. By utilizing the characteristic that a metal concentrating mill and the like have low requirements on water quality, pumped underground water is directly sent to the concentrating mill to be recycled as supplemented water; so the usage amount of a clean water source is reduced, and the expensive cost fortreating polluted water is saved.
本发明公开了一种打井截流修复地下水污染的方法，具体涉及水污染防控领域，以污染区域地下水中的污染源为中心环绕设置多组修复系统，每组所述修复系统均包括主抽水井和辅助抽水井，所述辅助抽水井设置于靠近污染源来源一侧，所述辅助抽水井两侧以及主抽水井远离辅助抽水井的一侧均设有监测井；具体修复步骤如下：S1、单井、多井抽水实验，污染地区周边地区水文地质参数确定；S2、确定最佳截流区域；S3、确定打井位置和数量；S4、污染区域地下水污染的防控及修复。本发明利用金属选矿厂等对水质要求不高的特点，抽取的地下水直接送往选矿厂作为补水回用；一方面减少了洁净水源的使用量，另一方面又省去了处理污染水的昂贵费用。
