Abstract

The invention belongs to the technical field of polluted groundwater environment restoration engineering, and specifically provides a groundwater light non-aqueous phase liquid pollutant cleaning system. The system comprises a sewage treatment module, a groundwater extraction well containing a groundwater layer and a light non-aqueous phase liquid layer, wherein the light non-aqueous phase liquidlayer floats on the surface of the groundwater layer, and the system also comprises a groundwater level monitoring module, a liquid phase extraction module and a gas phase extraction module, wherein the groundwater level monitoring module is used to monitor a liquid level of the groundwater extraction well in real time, and feedback the liquid level to the liquid phase extraction module and the gas phase extraction module; the liquid phase extraction module is used to extract a light non-aqueous phase liquid located on the surface of groundwater to a sewage treatment module according to the liquid level; and the gas phase extraction module is used to evacuate the upper part of the groundwater extraction well to form a negative pressure to the sewage treatment module according to the liquidlevel. The system can greatly improve the restoration efficiency and restoration effect of the non-aqueous phase liquid, can reduce or eliminate the affection of the "tailing" effect, and avoids expansion of a pollution scope of the non-aqueous phase liquid.

Description

technical field [0001] The invention belongs to the technical field of environmental restoration engineering of polluted groundwater, and in particular relates to a system for cleaning light non-aqueous liquid pollutants in groundwater. Background technique [0002] Groundwater is an important part of water resources. Due to its stable water quantity and good water quality, it is one of the important water sources for agricultural irrigation, industrial mining and cities. In addition, groundwater has the characteristics of wide distribution and excellent water quality. The role of groundwater in people's lives cannot be ignored. However, due to people's conscious or unconscious destruction, such as the discharge of urban sewage, the discharge of industrial "three wastes", the use of a large number of pesticides and fertilizers, etc., the problem of groundwater pollution has become more and more serious. [0003] Groundwater remediation technologies include extraction-treatm...
