Description
Technical field
It deoils prosthetic device the present invention relates to oil-contaminated soil processing technology field more particularly to a kind of oil-contaminated soil.
Background technique
China is one of big oil-producing country, the world ten, and it is more to have explored oil field quantity, and distribution is wide.Crude oil is in exploration, exploitation, transport
And soil can be polluted during storage, crude oil, which enters soil, makes soil become oily soil, and oil soil is sent out because crude oil exists
The variation of physiology property, such as crude oil blocking soil aperture, cause the soil organism at the Nomenclature Composition and Structure of Complexes for changing the soil organism
Carbon-nitrogen ratio (C/N) and carbon-phosphorus ratio (C/P) variation, cause soil microbial community, the variation of microbiota etc..Oily soil can
The underproduction of grain is directly resulted in, the edible plants and plant product being grown on oily soil can have an impact the health of the mankind.Crude oil
Class is making object and the main residual hazard ingredient of fruit parts is multiring aromatic hydrocarbon, toxicity of the arene substance to people and animal
Greatly, especially bicyclic and tricyclic is that the polycyclic aromatic hydrocarbon toxicity of representative is bigger；Multiring aromatic hydrocarbon substance can be connect by breathing, skin
The modes such as touching, diet intake enter in humans and animals body, influence the normal function of the organs such as its liver, kidney, or even cause canceration.It is former
Oil can be also made up of the transfer of pollution and the pollution of underground water to the bad stress on environment for human survival many levels.Oil
The presence of soil has seriously affected economic development, ecological environment and the agricultural production of China field area, become local society, economy and
