Device for remediating underground water heavy metal pollution

Abstract

The invention provides a device for remediating underground water heavy metal pollution. The device comprises an isolation system, a soil remediation system and an underground water remediation systemand is characterized in that the isolation system comprises an isolation wall and an isolation area which is vertically communicated and sealed on the periphery, and the isolation area is formed by the isolation wall in an enclosed manner; the soil remediation system comprise a spraying tank, a plurality of sprayers and remediation plants, and the sprayers are located above the isolation area andconnected with the spraying tank through a conveying pipe; the underground water remediation system comprises an oil extraction well, a quartz sand filter tank, a heavy metal reaction tank, an activated carbon filter tank and a plurality sprayers which are sequentially connected through a conveying pipeline. The device has the advantages that isolation, soil remediation and underground remediation are combined to overcome the defects that the prior art needs to perform remediation repeatedly and is high in cost, contaminated soil and underground water can be continuously remediated, and the device is low in operation cost, lasting in effect, scientific and reasonable in overall structure, simple and compact, convenient to mount and use and widely applicable to underground water remediation.

Description

technical field [0001] The invention relates to groundwater restoration equipment, in particular to a restoration device for groundwater heavy metal pollution. Background technique [0002] With the rapid development of industry and agriculture, the pollution of heavy metals in groundwater has intensified, and the pollution situation has become increasingly severe, especially industrial wastewater, waste residues, heavy metal-containing pesticides, and chemical fertilizers have caused heavy metal pollution in groundwater, resulting in a sharp increase in the content of heavy metals in groundwater, which seriously affects the human body. health and ecological safety. [0003] At present, the remediation technology of heavy metal pollution in groundwater mostly adopts pumping out heavy metal-contaminated groundwater for water purification and pollutant removal, and then refilling the treated water that meets the relevant standards into the underground target aquifer, so as to ...
