Abstract

The invention belongs to the technical field of polluted underground water treatment, and more particularly relates to a method and system for repairing polluted underground water by utilizing horizontal pipes. Horizontal pore channels are formed in an underground water restoration area, and the horizontal pipes are arranged; the horizontal pipes are mainly used for collecting and treating underground water; and the working range of the horizontal pipes can be extended to 40 meters or above, so that the deep underground water in-situ remediation treatment can be realized. The difficulty that the deep underground water is difficult be repair by using the current PRB (permeable reactive barrier) technology is overcome, and the difficulty of accurately controlling the treatment elevation range of the underground water by adopting a method of discharging the underground water by using a well group is also overcome. The method and system for repairing the polluted underground water by the horizontal pipes are small in technical quantity and low in cost, and can accurately control the repair range, and simultaneously, the horizontal pipes can be used for collecting the underground waterfor a long time after the horizontal pipe is driven into underground, so that the later operation maintenance cost is low. With the method and system provided by the invention, the collection and treatment efficiency of the polluted underground water are higher and the effect is better.

Description

technical field [0001] The invention belongs to the technical field of polluted groundwater treatment, and more specifically relates to a method and system for repairing polluted groundwater by using horizontal horizontal pipes. Background technique [0002] At present, groundwater remediation includes permeable reactive wall (PRB) technology, groundwater collection well group extraction groundwater remediation technology. PRB technology requires a large amount of engineering and high cost, and it can only restore shallow groundwater, but cannot restore deep groundwater. The groundwater recovery technology for groundwater collection wells extraction and groundwater restoration requires a large amount of engineering, high extraction and water treatment operation costs, and difficult post-maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for repairing polluted groundwater by using horizontal horizontal pip...
