Groundwater Restoration System and Restoration Method

Abstract

The embodiment of the present application discloses a groundwater restoration system and restoration method, which are used to ensure the continuity of the groundwater restoration effect. In the groundwater remediation system provided in the embodiment of the present application, the circulating well includes an inner well screen, an outer well screen and a well cover. The screen includes the first screen section and the second screen section. The aeration pipe of the aeration system extends into the inner well screen and connects with the aeration head. When the middle screen rotates to the first position, the screen on the first screen section The holes are aligned with the sieve holes on the corresponding inner well screen, and the sieve holes on the second screen section are staggered from the sieve holes on the corresponding inner well screen, so that the screen holes on the corresponding inner well screen The hole is closed. When the middle screen rotates to the second position, the screen hole on the second screen section is aligned with the screen hole on the corresponding inner well screen, and the aeration head is set between the second screen section and the circulation well. between the bottom.

Description

technical field [0001] The invention belongs to the technical field of groundwater pollution restoration, and in particular relates to a groundwater restoration system and a restoration method. Background technique [0002] The main sources of groundwater organic pollution include the use of pesticides and fertilizers, oil leakage, and the random placement and discharge of organic wastes by factories and enterprises. Among them, the main component of soil oil pollution is C 15 -C 36 alkanes, olefins, benzene series, polycyclic aromatic hydrocarbons and phenols, etc., of which there are as many as 30 pollutants under limited environmental control. The pollutants in the surface soil of the polluted site mainly penetrate the vadose zone and enter the submerged aquifer by means of vertical migration. Therefore, the pollution of diving is inseparable from the pollution of the topsoil and the rock and soil of the submerged aquifer. After the pollutants enter the topsoil, under ...

AI Technical Summary

Problems solved by technology

However, once the circulating well repair system stops operating, the bound non-aqueous liquid will continue to be discharged into the water body as a persistent pollution source, which will pollute the water body again

[0005] To sum up, the existing groundwater remediation technology has the problem of poor remediation effect sustainability
