Method.
Gas phase extracting (vapor extraction, VE) is to carry out original to the volatility organic contamination in soil and groundwater
A kind of method that position is repaired, for handling the pollution problem of stratum media in aeration zone.The basic principle of gas phase extracting is to utilize
Vacuum pump extracting generates negative pressure, when air flows through Polluted area, desorbs and carries the volatility in soil aperture or in underground water secretly
And half volatile organic contaminant, it is taken away by air-flow, the final process after extraction well is collected reaches purification aerated zone soil
With the purpose of underground water.Sometimes while extracting, gas injection well can be set, air is manually passed through into soil.The gas of extraction
Body will pass through except the processing such as steam and absorption heel row enters air, or according to the difference of pollutant, using corresponding gas treatment
Technology.
The in-situ immobilization used at present often only solely extracts recovery technique using biological prosthetic or gas phase, repaiies
It is multiple it is inefficient, repair time is long, and need to energize using the additional energy in repair process, be unfavorable for it is energy saving same
When easy to produce secondary pollution, constrain the development of environmentally friendly recovery technique.
