In-situ remediation method for underground water
The in-situ remediation method comprises the steps that a plurality of remediation wells are built in an underground water polluted area, remediation filler is laid and filled to form a remediation layer, the remediation layer comprises a first remediation layer and a second remediation layer arranged below the first remediation layer, and the thickness ratio of the first remediation layer to the second remediation layer is (2-3): 1; the first repairing layer comprises siderite particles and pyrite particles according to the mass ratio of 1: 1, and the second repairing layer comprises modified zeolite and nano zero-valent iron according to the mass ratio of 1: 1; a water pumping pipeline is arranged in the well pipe to be communicated with an underground water layer going deep into the well pipe to be repaired, a plurality of branch water pipes are arranged above the repairing layer in the horizontal direction, and a plurality of water outlet holes are evenly formed in the upper portion of the repairing layer; and the water suction pump is started, underground water needing to be repaired is sucked into the multiple branch water pipes, the underground water leaks to the repairing layer through the water outlet holes of the branch water pipes for repairing, and the underground water is discharged after repairing. The underground water remediation effect is remarkable, the situation that remediation is not in place is avoided, and it is ensured that the quality of underground water reaches the standard.
本发明公开了一种地下水的原位修复方法，包括：在地下水污染区域建设多个修复井，铺设填充修复填料形成修复层，修复层包括第一修复层和设置于第一修复层下方的第二修复层，二者厚度比例为2～3：1，第一修复层包括质量比1：1的菱铁矿颗粒和黄铁矿颗粒，第二修复层包括质量比1：1的改性沸石和纳米零价铁；在井管内设置抽水管道与深入需要修复的地下水层连通，在修复层上方沿水平方向设置多个分支水管，多个出水孔被均匀设置于修复层的上方；启动抽水泵，将需要修复的地下水抽吸至多个分支水管中，并通过分支水管的出水孔渗漏到修复层进行修复，修复后排出。本发明对地下水的修复效果显著，避免修复不到位的情况出现，确保地下水质量达标。
