Description
Technical field
The utility model relates to pollution remediation technology fields, more particularly to one kind for repairing polluted underground water and its stream
Device through contaminated soil.
Background technique
The pollution of soil and underground water will affect the health of the mankind, for example, industrial processes are likely to result in soil
The pollution of earth and underground water, if people's health will be directly affected using the underground water of pollution as life water source.Meanwhile such as
Fruit touches contaminated soil and underground water, or the pollutant that sucking is evaporate into air from contaminated soil and underground water,
It all will affect people's health.Soil and underground water if it is farming land is contaminated, then can cause adverse effect to crops,
Eating the crops will affect people's health.The reparation of soil and underground water pollution is very important.
In practical application, comparatively, the pollution of soil and underground water is more refractory reason, the reason is that: soil and
Underground water is directly exposed in ground surface environment unlike surface water or atmosphere, but has the characteristics that concealment and uncertainty,
The region of soil and underground water pollution and range is caused to be difficult to define；Underground environment is complex, and technology is implemented by many factors
It influences, therefore repair time is long, rehabilitation cost is high.It is clear according to whether being carried out for the recovery technique of soil and underground water
It digs post-processing and is divided into based technique for in-situ remediation and showering technology.
(1) showering technology
Showering is that the origin-location that contaminated soil or underground water are polluted from place is excavated or extracted
Come, carries or be transferred to other venue locations and carry out comprehensive treatment reparation.Under normal circumstances, the showering technology duration it is shorter,
Pollutant removal is good；But its expense implemented is relatively high, may destroy ecological environment of soil, be distributed in building more
Site is difficult to carry out, and be easy to cause the secondary pollution etc. of surrounding enviroment.
(2) based technique for in-situ remediation
Based technique for in-situ remediation is not move contaminated soil or underground water, and the position directly polluted in place is to it
The technology of original place reparation or processing is carried out, control expense is relatively low, and effect on environment is small, and many technologies can handle soil simultaneously
With underground water, but it usually requires the longer implementation cycle.
Currently, equipment used by more common Pump-and-Treat technology includes pumped well and returns in based technique for in-situ remediation
Well is infused, pumped well captures the Pollution Plume water body of underground and draws it out ground, then using sewage disposal technology by Water warfare, then
Purified water body is refilled into underground by reinjection well.Specifically can by the way of Pump-and-Treat-discharge, or extraction-
The injected mode in processing-upstream carries out underground water and soil pollution processing.Using any one of both modes, can all make
At the SEA LEVEL VARIATION near pumped well or reinjection well, and then the direction of groundwater flow near pumped well or reinjection well is influenced, and can be right
Underground water pollution generates the effect of traction or passage, that is, easily causes underground water pollution to spread, it is lower to eventually lead to remediation efficiency.
