Quaternary underground water and soil pollution treatment method
The invention belongs to the field of underground water and soil pollution treatment, and discloses a quaternary underground water and soil pollution treatment method. The method is mainly technically characterized by comprising the following steps: pollution boundaries are roughly presumed according to a ground pollution source, an underground water runoff direction and pollution time; exploratory holes are drilled, and the pollution boundaries are determined; testing recharge wells are constructed on the edge of a contaminated site, the underground water influence radius R of the recharge wells is tested, the recharge wells are drilled at the positions away from the outer side of the boundary of the contaminated site by the underground water influence radius R, and the interval between every two adjacent recharge wells is smaller than 2R; step4, a horizontal well is constructed, horizontal well spacing is not greater than the groundwater influence radius R, a horizontal well water filter pipe is constructed by clinging to the water-resisting layer surface according to the stratum condition and covers the whole polluted area in length; and a water storage tank is dug on the ground surface in the determined polluted area, and polluted water in the polluted area is pumped out through the horizontal well and treated while clean water is recharged into the recharge wells. The treatment is more thorough, and the damage of surrounding buildings caused by underground water level decline is avoided.
本发明属于地下水及土壤污染处理领域，公开了一种第四系地下水及土壤污染处理方法。其主要技术特征为：根据地面污染源及地下水径流方向和污染时间，大致推定污染边界；打勘探孔，确定污染边界；在污染场地边缘施工测试回灌井，测试回灌井的地下水影响半径R，在距离污染场地边界外侧地下水影响半径R处打回灌井，相邻回灌井的间隔小于2R，第四步，施工水平井，水平井间距不大于地下水影响半径R，水平井滤水管根据地层情况紧贴隔水层面施工，长度覆盖整个污染区域；在确定的污染区域内地表挖储水槽，向回灌井中回灌清水的同时通过水平井抽出污染区域内的污染水并处理。处理更加彻底，避免了周围建筑物因地下水位下降造成的损坏。
