Embodiment 2

[0038] A groundwater pollution remediation method, by placing a permeable reaction wall downstream of the groundwater pollution source, the structure of the permeable reaction wall is as follows figure 1 shown. When the polluted groundwater passes through the permeable reaction wall, the heavy metals in the polluted groundwater are removed by precipitation and adsorption. The permeable reaction wall includes an outer layer and an inner layer filler 1, the outer layer is a permeable wall 2, and the permeable wall 2 is filled with zeolite 3. The filler in the inner layer is an oxide compound. The upper end of the permeable reaction wall extends above the ground, the upper end of the permeable reaction wall has an opening 5, and a top cover 4 is provided at the opening to cover the permeable reaction wall. When the inner layer packing needs to be replaced, it is only necessary to take out the original inner layer packing from the opening 5 and replace it with a new inner layer ...

Abstract

The invention discloses a groundwater pollution remediation method. A permeable reactive wall is placed on the downstream of a groundwater pollution source, when the polluted groundwater passes through the permeable reaction wall, heavy metals in the polluted groundwater are removed through precipitation and adsorption, the permeable reactive wall comprises an outer layer and an inner layer filler, the outer layer is a permeable wall body, and the inner layer filler is an oxide compound. The groundwater pollution remediation method adopts the self-made inner layer filler to treat the pollutedgroundwater, the heavy metals like Cr, Pb and Cd contained in the polluted groundwater can be outstandingly removed, the remedied groundwater contains less heavy metals, and can completely meet the standard requirements.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a groundwater pollution restoration method. Background technique [0002] Groundwater provides human beings with valuable water sources, and is also an important part of the natural water cycle and water resources. At present, more than 400 cities in my country use groundwater as their water supply source, and some cities even use groundwater as the only source of water supply. However, with the acceleration of urbanization, the rapid development of industry, and the mining and smelting of mineral resources, the problem of heavy metal pollution in groundwater has become increasingly prominent. Heavy metal pollution is closely related to the mining and smelting of mineral resources. For example, in Hunan, Shaanxi, Qinghai and other provinces with relatively developed ore mining industries, heavy metals in groundwater in some areas seriously exceed the standard. ...
