At present, with the industrial structure adjustment and fulfil《Stockholm on persistence organic pollutant (POPs)
Pact》What is worked is carried out in a deep going way, large quantities of insecticide factories, steel plant and chemical plant Deng Gao contaminating enterprises, and particularly POPs is produced and made
To progressively be closed down with enterprise and change the line of production or move, wherein existing 86000 enterprises in the whole nation stop production or move between 2001 to 2007 years,
Generate a large amount of high pollution risk soil.The harmfulness of soil pollution be some organic matters after soil is polluted, can enter
And the air and water on contaminated soil periphery, and some organic matters or heavy metal pollution are produced bad then by food chain to human body
Influence.The quickening of urbanization process promotes the transformation of original land function, and a large amount of industrial lands are changed to residential land, but these
The pollution problem that place is present have impact on redevelopment and utilize.Contaminating enterprises move the environmental pollution accident of initiation and to health
The incident of injury happens occasionally throughout the country, has become Land Development and triggers one of principal element of environment difficulties, dirty
Dye soil remediation work is very urgent.
Domestic volatile organic matter contaminated site area is wide, and pollution level is deep mixed, and contaminant component is complicated, seriously
Limit the development and dilatation in city.For the unsaturated soil of VOC class Substances Pollutions, existing recovery technique mainly has gas phase
Extracting, thermal desorption, cement kiln burning and landfill etc..But gas phase extraction technique long operational time, it is impossible to meet industry in city dirty
The dye thermophilic demand leaved for development in place；Thermal desorption is relatively costly, it is impossible to for processing large batch of contaminated soil；Burn and landfill skill
Art secondary pollution risk is big, relatively costly and treating capacity is limited.So, traditional soil restoring technology is difficult to meet and increasingly changes
The market demand.
Traditional soil restoring technology, then during repairing organic polluted soil, to thermal desorption organic gas out
Without treatment, secondary pollution is easily produced.
The content of the invention
To solve the defect of above-mentioned technology, a kind of special organic matter soil remediation for not producing secondary pollution of offer of the present invention is filled
Put.
Technical scheme is as follows：

In such scheme, the soil remediation case inside bottom is provided with equally distributed electric heating tube, the electric heating tube
Dividing plate is provided with, the soil remediation chamber interior wall is provided with temperature controller.
In such scheme, the core of the film separation system is complete membrane module, and the core component of the membrane module is excellent
First organic matter film thoroughly.
In such scheme, the film separation system film downstream lateral pressure is maintained at 3~10kPa.
In such scheme, the film separation system film downstream lateral pressure is maintained at 100~102kPa.
In such scheme, detection means is provided with the soil cooler bin.
In such scheme, the detection means is content of organics detector, and the content of organics detector is arranged on
The interior but chamber interior wall bottom of soil.
The soil for needing to repair when in use, is first put into soil breaking case by the present invention, after being crushed through soil breaking case
Soil is heated into soil remediation case, and question response opens air blower and vavuum pump afterwards for a period of time, and the tail gas that will be separated leads to
Enter film separation system, condenser is passed through rich in organic gas through what film separation system was isolated, condensed organic matter enters
Organic matter collecting tank, the soil after reparation enters soil cooler bin, and repairing quality is detected after cooling, and soil is passed through after passed examination
Drawing mechanism discharges.
In sum, the beneficial effects of the invention are as follows：
1st, the present invention can continuous feed, contaminated soil treating capacity is big；Take the mode of directly heating, thermal desorption efficiency high.
2nd, the present invention uses film separation system, and tail gas is processed, and will not produce secondary pollution.
3rd, the present invention sets detection means, detects soil remediation situation, it is ensured that the quality of soil remediation.
