Description
Technical field
The present invention relates to visualization technique field, it particularly relates to a kind of 3D pattern dies repaired for contaminated site
Plan method.
Background technology
With expanding economy, the fast development of petroleum industry, on petrochemical industry production district, gas station and other places, due to falling
The reasons such as ground oil, oil pipeline seepage and the discharge of oil-containing production waste, cause substantial amounts of petroleum pollution to enter underground layer, cause
Soil and groundwater pollutes.The pollution of oil and its side-product to environment is increasingly severe, has injured the mankind and animals and plants
Existence with health.Because oil and its side-product include the volatile organic matters such as benzene, oil to the pollution main component of environment
In organic hydrocarbon often exist with liquid form, and be insoluble in water, density ratio water is little, therefore is referred to as lightweight non-aqueous phase liquids
（Light Non-aqueous Phase Liquids, LNAPLs）.LNAPLs can under gravity in soil after being leaked by point source
Vertical transfer in earth aeration zone to interface on capillary saturation region starts laterally to sprawl, and is extended down to groundwater level always, final to float
The lenticular body of LNAPLs is formed on groundwater level.
At present, the progress with the Chinese government and environmental worker to underground water pollution, than more typical soil and
Groundwater remediation technology mainly has monitoring natural attenuation recovery technique（MNA technologies）, pump-and-treat system recovery technique（P＆T technologies）With
Based technique for in-situ remediation.P＆T technologies are the earliest soil and groundwater remediation technologies for occurring, will subsoil water take out from original position
Go out, filled back after strange land is repaired again in the position at subsoil water place.But due to the effect of capillary tension, it is trapped in water layer
Non-aqueous solution almost cannot extract out from pump, so being poorly suited for the pollution amelioration of oil and its side-product.And MNA skills
Art relies primarily on itself damping capacity of the physico chemical factor and pollutant of IA and is repaired, therefore is applied to contaminant capacity ratio
The not serious region of less, pollution condition, and for the Polluted areas such as Oil spills are not appropriate for.Based technique for in-situ remediation is mainly
Carry out inside soil and subsoil water, rehabilitation cost is low, effect is good, restorative procedure is varied, to the disturbance of restoring area very
It is low, applied widely, therefore, during following soil and groundwater pollution amelioration, based technique for in-situ remediation will be more and more
Be applied to the actual repair process especially place polluted by oil and its side-product.Based technique for in-situ remediation includes biology in situ
Recovery technique, peripheral doses technology in situ and in-situ chemical recovery technique, although the remediation efficiency of physics in situ and chemical method is very
Height, but which easily causes secondary pollution, and the economical strong, safe green of continuable biology in situ method, to place ring
The technology of any secondary pollution is not caused in border, while the daily operation in place is had little influence on while construction at the scene.But
The premise for using is repairing for the concentration distribution of pollutants to contaminated site, spatial distribution and contaminated site based technique for in-situ remediation
Multiple soil boundary and rehabilitating soil amount have one clearly to recognize, so as to the information such as the injection phase to medicament, injection rate ability
Accurately decision-making is made enough.High-precision data analysiss are the fundamental basis for processing soil and groundwater pollution, so place is repaiied
Multiple top priority is exactly by understanding impact of the pollutant to soil and groundwater in place, completing the composition of Polluted area.
There are both at home and abroad numerous soil ground water regime POLLUTION SIMULATION softwares, but the precision of these simulation softwards
It is also to be discussed with accuracy.The prototype software invented by this patent is to adopt with the hydrological geological conditions of contaminated site and on the spot
Sample analysis result data is foundation, and combined with sensing technology can present the 3D models of real-time soil and lower water environment, so as to allow
Pollution in place is precisely presented in the form of vertical distribution figure.Newest 3D visualization techniques are combined at sensor, digitized
Reason and computer technology can help client only need to cooperate with a unit just can obtain include Sample Data Collection, place
Reason and analyze it is interior and can generate 3 dimensional drawing, the entirety on mobile device can be delivered in real time by network
Service.The combination of 3D models and continuable based technique for in-situ remediation can help owner is carried out with regard to how to control risk and carry out
Site remediation decision-making, so as to design the recovery scenario of most cost performance.
