Embodiment 1

[0037] refer to figure 1 and figure 2 , is a vortex-solidified groundwater restoration system disclosed by the present invention, which is set in the groundwater repair area 1, including a pumping well 2, a water injection well 3 and a fence 5, and the pumping well 2 is set in the center of the repairing area 1, with a diameter of 20- 40cm. The depth is drilled below the groundwater pollution layer, and a water pump is arranged in the pumping well 2 for pumping water outwards. A plurality of water injection wells 3 are evenly spaced along the outer contour of the restoration area 1 , the diameter of the water injection wells 3 is 20-40 cm, and the distance between adjacent water injection wells 3 is 2-4 m. The depth is drilled below the groundwater pollution layer, and the depth is shallower than that of the pumping well 2. Multiple water injection wells 3 surround the repair area 1 to form a circular recharge well group. The distance between the water injection well 3 and ...

Embodiment 2

Abstract

The invention relates to a vortex solidification underground water remediation system. The vortex solidification underground water remediation system is arranged in an underground water to-be-remediated area, and comprises a pumping well, water injection wells and fences. The pumping well is formed in the center of the to-be-remediated area, the multiple water injection wells are arranged at intervals along the outer contour line of the to-be-remediated area, an inorganic inert adsorption material is injected into the water injection wells, and the closed adsorption material fences are formedon the outer side of the to-be-remediated area, wherein the adsorption material fences have good water permeability, and the height of the fences is at least equal to the covering depth of polluted underground water. By performing large-drawdown pumping on the pumping well and large-flow reinjection on the water injection wells, a cone of depression is formed, and after the adsorption material adsorbs pollutants in the underground water, the pollutants are degraded and solidified, gather towards the pumping well group along with the migration of the underground water and then are pumped to thesurface through the pumping well group for surface treatment and purification. The vortex solidification underground water remediation system has the advantages of small pumping amount, short cycle and large treatment range.

Description

technical field [0001] The invention relates to the technical field of groundwater restoration, in particular to a vortex-solidified groundwater restoration system and a restoration method thereof. Background technique [0002] Groundwater is a precious freshwater resource for human beings. However, with the continuous development of social industrialization, wastewater discharge, industrial waste residue, agricultural irrigation, landfill leakage, and damage to transportation pipelines and storage tanks for petrochemical raw materials may cause groundwater pollution. It makes the original tense water shortage problem more serious, and poses serious threats and challenges to human health, food safety, drinking water safety, regional ecological environment, sustainable economic and social development, and even social stability. Groundwater restoration has become a public concern and environmental issues of social concern. [0003] At present, extraction technology is commonl...
