Soil pollution refers to that the species and content of pollutant in soil have exceeded soil background values, and animals and plants are caused with wound
Evil and the pollution situation of the healthy generation harm influence on the mankind.Soil pollution includes organic contamination and inorganic pollution two
Major class, usual organic pollution under certain condition, structure letter is resolved into by forms such as the illumination of long period, biodegradations
Single inorganic matter, the i.e. referred to as self-purification capacity of soil.So as social continuing to develop, because polluter enters soil
Content and speed are being continuously increased, and only by the self-purification capacity of soil, are extremely difficult to requirement of the people for soil cleanliness factor.
Contaminated soil, on the one hand planting plants, crops in contaminated soil, in harvesting grain, in the presence of certain pollutant；And
Due to the pollution of soil, for the cleanliness factor of underground water, also in the presence of certain threat；Potential safety hazard hence for people is caused
Certain influence.
The physical method for generally using, isolates pollutant in soil, then pollutant is vaporized or is divided by high temperature
Solution.But the method cost is very high, but also air can be polluted.
The content of the invention
