Modular underground water permeable reaction pile and implementation method thereof

Abstract

The invention discloses a modular underground water permeable reaction pile and an implementation method thereof. The method comprises the steps that a reaction pile hole is dug; a prefabricated reaction pile outer frame body is installed in the reaction pile hole, wherein the reaction pile outer frame body comprises a plurality of frame body units which are sequentially arranged from bottom to top and are provided with preset seepage holes for water to flow out; a prefabricated medium loading module is placed in the frame body unit, wherein the medium loading module is filled with a reactionmedium; an underground water circulating device is arranged in the medium loading module; and the underground water circulation device is used for carrying out circulation treatment on underground water of the polluted stratum, so that the qualified underground water treated by the medium loading module is discharged out of the reaction pile outer frame body through the preset seepage holes, and the treated unqualified underground water is treated by the medium loading module again to form the modular underground water permeable reaction pile. According to the method, the construction of the underground water permeable reactive barrier under complex stratum conditions or deep parts can be realized, each device can be repeatedly used, the treatment is environment-friendly, and the cost is low.

Description

technical field [0001] The invention relates to the field of groundwater and soil pollution restoration and treatment of environmental governance, in particular to a modular groundwater permeable reaction pile and a realization method thereof. Background technique [0002] The groundwater permeable reaction wall is an in-situ treatment system for the remediation and treatment of groundwater and soil pollution. Specifically, after the groundwater in the soil passes through the permeable reaction wall, the heavy metals or organics in the groundwater will degrade and precipitate with the remediation medium in the reaction wall. A series of physical, chemical or biological actions such as adsorption and adsorption to achieve the restoration of groundwater to achieve a certain discharge index is an in-situ restoration method that uses natural or artificial groundwater hydraulic gradients to achieve.
