Problems solved by technology

[0005] The existing PRB (permeable reaction grid) technology is greatly affected by the hydrogeological conditions on site. This application can only be used to repair the water pollution of the abandoned lead and zinc processing plant. The treatment of water pollution did not achieve the expected effect; in addition, in the process of water pollution repaired by PRB technology, when the filler in...

Abstract

The invention discloses a PRB module for underground water pollution restoration, which comprises a permeable wall, a permeable reaction belt, an injection well and a monitoring well, wherein the permeable wall is used for adsorbing and isolating solid pollutants, the permeable reaction belt is arranged at the bottom of the permeable wall, two ends of which are connected with the two ends of the permeable wall, the cross-section is of a circular arc shape, a plurality of injection wells are arranged in the permeable reaction belt, and a reaction processing unit is arranged in the injection well; the permeable wall provided by the PRB module for underground water pollution restoration has the advantages that parts of the pollutants are attached to the PRB active filler column, the permeablereaction belt is in a circular arc shape so that the reaction area with the ground water pollution is increased; the reaction processing unit is arranged in the injection well, so that the underground water passing through the permeable reaction belt is restored, meanwhile, the PRB active filler column is detachably arranged below a mounting bracket, therefore the replacement is convenient, the replacement difficulty and the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of water pollution restoration, in particular to a PRB module used for groundwater pollution restoration. Background technique [0002] As a precious fresh water resource for human beings, groundwater has been polluted to varying degrees with the continuous development of industrialization in modern society. Since the 1960s, groundwater pollution has gradually increased, so groundwater restoration technology has also been developed. [0003] Groundwater pollution remediation technologies include ex-situ remediation, in-situ remediation and monitoring natural attenuation technologies. Ex-situ remediation technology is a technology that pumps contaminated groundwater to the surface for treatment. This technology has a large processing capacity and high processing efficiency in a short period of time, but long-term application generally has phenomena such as tailing and rebound, which ultimately reduces proce...
