Efficient groundwater remediation system and method

Abstract

The invention provides an efficient groundwater remediation system. The efficient groundwater remediation system comprises an intercepting ditch, a water collecting well, a sewage treatment system and a water purification tower, wherein the intercepting ditch is arranged at the downstream of a groundwater pollution area and used for intercepting groundwater in the groundwater pollution area; the water collecting well is arranged in the intercepting ditch and is used for collecting the groundwater intercepted by the intercepting ditch; the sewage treatment system is used for treating the groundwater in the water collecting well; the water purification tower comprises a vertically arranged third pipeline, the lower end of the third pipeline is buried underground and arranged at the upstream of the groundwater pollution area, and the groundwater treated by the sewage treatment system returns to the underground through the water purification tower. According to the efficient groundwater remediation system, the groundwater in an groundwater polluted area can be efficiently repaired.

Description

technical field [0001] The invention relates to the technical field of groundwater pollution restoration, in particular to an efficient groundwater restoration system and method. Background technique [0002] Groundwater is one of the important water resources in my country, and the drinking water in more than 400 cities comes from groundwater. In recent years, with the intensification of industrial production activities, excessive use of pesticides and fertilizers, and the aging and leakage of chemical production and storage facilities, the situation of groundwater pollution in my country has become more severe. [0003] Groundwater interception ditch is an underground project used to quickly collect polluted groundwater. Its operation can significantly increase the collection rate of polluted groundwater in low-permeability strata, and effectively intercept the migration of groundwater pollution plumes. It is a simple and practical risk management and control of polluted g...

Problems solved by technology

[0005] However, the infiltration rate of groundwater is extremely slow, and the use of interception trench technology to restore groundwater is a long-term project. A typical case is the US Marine Corps training base Camp Lejeune in Onslow County, North Carolina. A set of interception ditch extraction systems were installed in the downstream of each. After 2.5 years of operation, the two sets of interception ditch systems effectively intercepted the spread of groundwater pollution plumes to the periphery and gradually reduced the concentration of pollutants in groundwater. The average concentration of the series is close to the undetected
