Method and system for remediation of contaminated groundwater by adopting horizontal transverse pipes arranged in radiation type

Abstract

The invention belongs to the technical field of contaminated groundwater treatment, and more specifically relates to a method and system for remediation of contaminated groundwater by adopting horizontal transverse pipes arranged in a radiation type. According to the method provided by the invention, channel groups are arranged in the remediation areas of groundwater to place the transverse pipe groups, and the transverse pipe groups and a water collecting vertical shaft work together, so that the collection area of the groundwater can be greatly increased, the efficiency of collection and treatment of the groundwater can be effectively improved, the in-situ remediation treatment of deep groundwater can be realized, and the elevation range of groundwater treatment can be accurately controlled; the number of water supply vertical shafts can be greatly reduced, the construction costs can be reduced, and the construction difficulties and safety risks can be reduced; the problem that the elevation range of groundwater treatment is difficult to accurately control through a method of discharging the groundwater by adopting pipe well groups is overcome, and the difficulty that a permeablereactive barrier cannot repair the deep groundwater is overcome; and according to the method and system for remediation of the contaminated groundwater by adopting the horizontal transverse pipes arranged in the radiation type, the technical project quantity is small, the construction cost is low, the horizontal transverse pipes can collect and treat the groundwater for a long time after being driven under the ground, and the operation and maintenance costs in the later period are low.

Description

technical field [0001] The invention belongs to the technical field of polluted groundwater treatment, and more particularly relates to a method and a system for repairing polluted groundwater by adopting radial horizontal horizontal pipes. Background technique [0002] At present, groundwater remediation includes permeable reactive wall (PRB) technology, groundwater collection shaft extraction groundwater remediation technology. PRB technology has a large amount of engineering and high cost. It can only repair shallow groundwater, but cannot repair deep groundwater. Groundwater collection shaft extraction and groundwater remediation technology, extraction and water treatment operation costs are high, and later maintenance is difficult. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method and system for repairing polluted groundwater by radiating horizontal horizontal pipes, so as to solve the problem that the existing groundwater ...
