Description
Technical field
Field is administered the invention belongs to heavy metal pollution of soil, and in particular to farmland soil heavy metals in situ detection and chelating
Trap controlling device and its application.
Background technology
Soil is the Open Dynamic system of a complicated multiphase, mainly including solid phase, liquid phase, gas phase and biofacies.Soil
Ecological functions are the embodiments of dynamic process that material is connected each other in soil heterogeneous system, mutually restricted.Soil pollution is to lead
The major reason for causing soil ecology deterioration even to lose.Contained a large amount of clay minerals and organic matter etc. in solid phase of soil,
Effectively its internal various pollution factor can be entered by sticking, and then be accumulated in soil, when being accumulated over a certain amount of, soil
Earth system output will directly or indirectly endanger biosystem, until health, i.e. soil pollution.
China's heavy metal pollution of soil situation is quite severe.Counted according to the Ministry of Agriculture, the soil face of China's heavy metal pollution
Product reaches up to ten million hectares, accounts for more than the l0% of total cultivated area, the annual grain up to 1.2 × 10 by heavy metal pollution in the whole nation7
Ton, causes grain drop in production to be up to 10 because of heavy metal pollution7Ton, amounts at least 20,000,000,000 yuan of economic loss；In the April, 2014 is sent out
Cloth《National Soil Pollution Investigation publication》And the heavy metal pollution event occurred for 2009 or so etc..It is above-mentioned to show soil
Earth heavy metal pollution turns into is related to economy and the great environmental problem of social sustainable development, causes extensive society to be closed
Note.
However, heavy metal pollution of soil administers high compared with water body, atmosphere heavy metal pollution difficulty of governance.Heavy metal pollution of soil
Difficult point is administered to show：First, soil is typically the simultaneous compound pollution of various heavy, is deposited in heavy metal in soil
In variform, the envirment factor such as the soil texture, organic matter, pH, oxidation-reduction potential and biosystem and heavy metal-polluted soil shape
State also has complicated associated effect；Second, soil matrix composition is complicated compared with water body, air, and content of beary metal is typically milligram
Every kilogram, ng/kg rank；3rd, the ecological functions of soil should be kept during soil remediation, to maintain biological life
Deposit.Above-mentioned improvement difficult point shows, using the strategy meeting of addition chemical stabilization heavy metals in soil due to different heavy metals
Stabilization effect differs, and causes final regulation effect undesirable, in addition, heavy metal also exists in natural environment after stabilizing
Activating risk and chemical agent influences the risk of soil environment ecological functions.
But further investigation is found, water-soluble state and exchange state may be up to total metalses in farmland soil heavy metals form
More than 60%, after being activated through heavy metal-polluted soil, proportion can reach more than 80%, and water-soluble state and exchange state heavy metal are to be easiest to
By the principal risk source of bio-absorbable, absorption and accumulation；In addition, under environmental influence, Carbonates In Soil reference state, have
Machine reference state and ferrimanganic reference state heavy metal can be converted to water-soluble state and exchange state, and residual form heavy metal element be it is stable,
It will not be discharged substantially under natural conditions.Therefore extracted using chelating resin and remove water-soluble state and exchange state heavy metal in soil, into
For a kind of potential possible strategy for removing heavy metal pollution of soil.
Heavy metal chelate resin is a family macromolecule compound, and it includes skeleton and chelating function group.Chelating resin is caught
Collection heavy metal mechanism be：In chelating resin in chelation group the atom such as N, O, P, S with lone pair electrons and the empty rail of metal ion
Road carries out ligand complex, forms rock-steady structure, and traps fixed heavy metal.
Current universally recognized Heavy Metal Pollution Control method is plant extraction method.This law point similar to plant extraction method
All it is processing by removing water-soluble state in soil, exchange state heavy metal ion, so as to reach removing heavy metals environmental risk
Purpose.Difference is that phytoremediation is biological repair mode, and enriching quantity is influenceed by organism biomass, enrichment rate it is low and
Influenceed by Biotope Landscape condition and upgrowth situation, it is difficult to handle high concentration heavy metal pollution, it is difficult to edit biological concentration heavy metal
Attribute of species etc.；And chelating trapping facture is chemical treatment method, with processing chelating heavy metal amount height, sequestration rate
It hurry up, Reaction conditions range is wide, can handle high concentration heavy metal pollution, be easy to realize editor by the function base for editing chelating resin
Heavy metals trapping attribute, the chelating resin of chelating resin can activate recycling etc..It is last it should be noted that, chelating trapping processing
Technology does not produce significant impact to soil environment condition, without taking a large amount of areas and space, therefore in technology implementation process easily
In with other repairing and treating technical tie-ups, such as phytoremediation, electro reclamation.
In addition, during heavy metals in farmland pollution control, Heavy Metal Pollution and regulation effect assessment are all by adopting
Collection pedotheque goes back to laboratory and tested and analyzed, and such detection and analysis appraisal procedure cost wastes time and energy, and will be without environment
The residual form heavy metal of risk is introduced into assessment system, impact evaluation result.
