Description
Technical field
The invention belongs to groundwater remediation fields, and it is anti-to relate more specifically to a kind of intermittent aeration funnel gate-type permeability
Answer wall (PRB).
The invention further relates to the methods for carrying out the reparation of groundwater pollution of refuse landfill biology in situ using above-mentioned PRB.
Background technique
The main disposal options of industrial solid castoff use the modes such as landfill, stockpiling, Tailings Dam substantially at present.Landfill is
Refer to and solid waste is filled to underground or is stacked to the solid pollution substance treating method on ground, whether is good for according to landfill site seepage prevention measure
Entirely, simple or sanitary filling field can be classified as.Long-term accumulation, the landfill yard land used of stockpiling and valuable urban development soil provide
Contradiction between source and ecological space becomes increasingly conspicuous.With the growth of landfill time, landfill site seepage prevention layer is damaged, percolate is let out
The risk of leakage increases.Heavy metal, organic pollutant in percolate cause to seriously threaten to soil groundwater environment.
With the development of technology, people make great progress in terms of underground water pollution reparation, and gradually form
More perfect groundwater remediation technical system and related specifications guide, wherein just including the determination side of groundwater remediation target
The contents such as method, the workflow of groundwater remediation, groundwater remediation technical research and engineering application.Permeable reaction wall skill
Art (Permeable reactive barrier, PRB), can be permanently effective as a kind of Remedy Technology of Contaminated Groundwater in situ
Running, small to underground water environmental perturbation, operation expense is low, has broad prospect of application.
Summary of the invention
The object of the present invention is to provide a kind of intermittent aeration funnel gate-type permeable reaction walls.
Groundwater pollution of refuse landfill biology in situ is carried out using above-mentioned PRB it is yet another object of the invention to provide a kind of
The method of reparation.
To achieve the above object, permeable reaction wall provided by the invention is intermittent aeration funnel gate-type permeability
Reaction wall (PRB), including underground water reaction main shaft, reparation well, permeable reaction processing unit, both wings cut-pff wall, water outlet prison
Survey pond and automatic control system；Wherein:
It repairs well to be placed in underground water reaction main shaft, repairing well includes pumped well and aeration well, is equipped with aeration in aeration well
Pipe, the aeration tube, which is installed on, repairs well centre bottom, and aeration well is provided with sample automatic acquisition device, repairs well and underground water
It reacts and is filled with filtrate between main shaft；Aeration tube connects the air compressor machine on ground, is controlled by automation aerating system；
Permeable reaction processing unit includes the reaction member component that several are sandwich, and adjacent single reaction is single
