AI Technical Summary

Technical Problem

In production enterprises, existing technologies are insufficient to effectively remediate soil and groundwater pollution without disrupting production activities, and there are also issues such as high construction difficulty and the risk of secondary pollution from chemicals.

Method used

A dual-phase extraction device is used, which combines extraction wells with vacuum pumps and pneumatic diaphragm pumps to extract groundwater and soil gas respectively. The gas is then treated using a gas-water separator and an activated carbon box to achieve in-situ and ex-situ combined remediation.

Benefits of technology

It enables efficient soil and groundwater remediation in producing enterprises without the need for chemical treatment or soil excavation, reducing construction difficulty and the risk of secondary pollution, and improving remediation efficiency and environmental friendliness.

Abstract

The utility model provides a double-phase extraction soil and underground water remediation device suitable for in-production enterprises, and by adopting a mode of combining in-situ remediation and ex-situ remediation, soil and underground water can be remedied at the same time. A double-pump extraction system is adopted, a vacuum pump and a pneumatic diaphragm pump are arranged to extract gas and liquid in an underground polluted area respectively, the influence radius is large, the extraction rate can be freely adjusted, and limitation of the extraction depth of a single-pump system is avoided. A two-stage steam-water separator is adopted for ground surface equipment, extracted soil gas is primarily treated, it is guaranteed that gas entering the rear-end activated carbon box body is relatively dry, and the adsorption performance of activated carbon is not affected. The device can realize large-range remediation and treatment of deep polluted soil and underground water on the premise of not influencing surface production activities, and has the advantages of low carbon, environmental protection, small plot disturbance, low construction difficulty, adjustable remediation range and the like, and surface equipment is simple to operate and can stably run for a long time.
