The present invention relates to a groundwater circulation device, and more particularly to a groundwater circulation device capable of simultaneously extracting and injecting groundwater.

Groundwater causes qualitative changes due to natural or human activities, which in turn affects normal use or endangers human health and the living environment. Contaminants generated by human activities, such as industrial and agricultural wastewater, industrial production, transportation or storage, causing chemical substances to penetrate into the ground may change the quality of groundwater and cause groundwater pollution. Especially in the surrounding soil or groundwater in petrochemical factories, gas stations and other places, steam, diesel or organic solvents are usually infiltrated, which easily contaminates the soil and groundwater.

The types of pollutants in groundwater include inorganic substances, organic substances, microorganisms and radioactive substances. According to the degree of its dissolution in groundwater, it can be divided into two major categories: water phase and non-aqueous phase.
