Description
Technical field
The present invention is that the process that a kind of soil inorganic thing pollutes is repaired granule and processes restorative procedure, belongs to agricultural soil and administers skill
Art field.
Background technology
In recent years, owing to population increases, industry fast development, solid waste is constantly stacked to soil surface and topples over, harmful
Waste water constantly permeates in soil, and the waste gas of motor vehicle emission, harmful gas and floating dust in air constantly drop to soil with rainwater
In earth.The raising of agriculture chemistry level, makes a large amount of chemical fertilizer and fallout of pesticide in environment, causes soil to suffer non-point source
The chance polluted gets more and more, and its degree is the most increasingly severe；Under the influence of soil erosion and eolian erosion etc., pollute face
Long-pending constantly expansion.
Within 2010, China is by nearly 20,000,000 hectare (20 of cultivated areas such as inorganic matter pollution, heavy metal pollution and Organic Pollutions
Ten thousand square kilometres) rise the most year by year；The land area of annual use organic agricultural chemicals is 2.8 hundred million hectares of (2,800,000 squares of public affairs
In) more than, soil pollution makes National Agricultural grain drop in production more than 13,000,000 tons, because of pesticide and Organic Pollution, radioactivity
Polluting, the economic loss that the other kinds of pollution such as pathogen contamination is caused is difficult to estimate.Therefore, every obstruction soil is just
Chang Gongneng, is reduced Crop yield and quality, is cried by the material of the remote-effects health such as grain, veterinary antibiotics
Do soil pollutant.
When harmful substance is too much in soil, exceedes the self-purification capacity of soil, cause composition of the soil, 26S Proteasome Structure and Function to become
Change；Microbial activities is suppressed, and harmful substance or its catabolite gradually accumulate in soil, by " soil → plant
→ human body ", or be indirectly absorbed by the body by " soil → water → human body ", reach the degree being detrimental to health, it is simply that
Soil pollution.
Soil inorganic pollutant are essentially from the industrial wastewater entered in soil and solid waste；Factory, the solid waste in mine
Thing such as mine tailing, barren rock, flyash and industrial refuse etc..With the municipal refuse of various pathogenic bacterias and (included doctor by sanitary installation
Institute) waste water, refuse and the barnyard manure etc. discharged；Nitrate, sulfate chloride, soluble carbonate salt etc. are common and big
The inorganic pollution that amount exists.These inorganic pollutions can make soil compaction, changes Soil structure, the soil salinization and impact
Water quality etc. endanger.
Soil remediation: refer to use physics, chemical or biological method to fix, shift, absorb, degrade or convert place soil
In pollutant so that it is content is reduced to acceptable level, or poisonous and hazardous pollutant are converted into the mistake of innocuous substance
Journey.Restorative procedure is divided into again in-situ immobilization and showering two kinds.Showering relates to cutting the earth and muck haulage, not only can destroy former
The Soil structure come, the problem that also can there is secondary pollution.

Support etc. environmental condition limit.The time of phytoremediation needs 3～5 years, it is meant that the time of falling into disuse of soil is exactly 3～5
Year, affect economic benefit.It addition, phytoremediation is relatively costly, every cube of soil reaches about 200 yuan, every mu of soil
Rehabilitation expense is up to 8～100,000 yuan.High cost be local government and peasant the most unaffordable.
Chemical leaching method.After using chemical agent such as surfactant, mordant etc. the heavy metal in soil to be leached out again
Carry out waste water process.This method not only cost is the highest, far above phytoremediation, and by new pollutant such as surface
Activating agent, mordant etc. bring soil into, and the physical arrangement of soil can be greatly affected.Become new polluter.
Soil moved in improve the original method.By buried for contaminated soil original place more than one meter or dig out and transport, then the backfilling new soil by cleaning；For greatly
The reparation of area contaminated soil not only needs substantial amounts of human and material resources, financial resources；Repair one mu of contaminated land in this way to want
Spend unit up to a million, and the source of clean soil is also difficult to ensure.It addition, soil moved in improve the original method is easily destroyed Soil structure, cause
Soil fertility and microecological environment decline, and the contaminated soil transferring to lower floor easilys lead to Organic substance and heavy metal
Release, transitions into subsoil water, causes new underground water pollution.
Microorganism elution method.By adding the microorganism species that Organic substance and heavy metal are had enrichment in soil, will
Organic substance and heavy metal are washed out.This mode not only cost is high, and microbial inoculum consumption is big, for large-area soil
It is difficult to collect due to microorganism leacheate for earth pollution, is actually difficult to operation.
Electrochemical process.Make water solublity heavy metal ion enrichment to cathode surface by the function of current in soil.This skill at present
Art is simply groped at laboratory.Owing to function of current distance is the least, and actual contaminated land area is too big, this skill
Art is difficult to carry out in engineering, and no matter its high running cost is difficult to bear.
