Description
Technical field
This utility model relates to a kind of experimental provision simulating aeration zone pollutant solute transfer, belongs to Leaching Experiments device.
Background technology
Aeration zone is atmospheric water and surface water carries out the hinge of moisture and energy exchange with saturated zone subsoil water, is also the earth's surface pollutant passages that enter subsoil water.Various pollutant different medium, variable concentrations environmental condition under migration characteristics, the soil body to pollutant absorption with degradation capability and accumulation different with transformation rule, study these mechanism can for the prediction of underground water pollution and prophylactico-therapeutic measures offer foundation.
Soil water curve oil pollution is an extremely complex physical-chemical-bioprocess, after petroleum hydrocarbons enters aeration zone, constantly infiltrate under the effect of gravity and the effect of capillary force, also produce volatilization, plant absorption, microbial degradation and solid particle absorption simultaneously.It is focus and the difficult point of current hydrogeological study to volatile organic contaminant (VOCs) research of Transport in unsaturation band.VOCs exists with gas phase and two kinds of phases of liquid phase at unsaturation band, and migrate by volatilization, shower and the diffusion etc. produced by Concentraton gradient or escape in air, water body, or moved out outside geologic body by bio-absorbable, and then air, water body, ecosystem and human life are caused great harm.Therefore, research volatile organic contaminant migration in unsaturation band is shifted to new management mechanisms most important.
All study aeration zone pollutant solute transport mechanism by indoor Leaching Experiments at present, its ultimate principle is to field representativeness aeration zone earth pillar (undisturbed soil or disturbed soil) in indoor, Leaching Experiments is carried out with human configuration or original state pollutant solution, by the test of filtrate water quality, analysis, study various hydrochemistry effect and pollutant migration mechanism in water body.Existing indoor Leaching Experiments device exists following not enough: (1) does not simulate the rainer of natural rainfall, troublesome poeration and simulation weak effect；(2) can not test for the migration of volatile organic contaminant, poor for applicability；(3) function singleness, is simply possible to use in Leaching Experiments.
