Description
Technical field
Heavy metal pollution processing technology field is the utility model is related to, is polluted more particularly, to a kind of heavy metals in farmland
Monitor early warning and real time processing system on-line.
Background technology
In recent years, the heavy metal pollution phenomenon of soil becomes getting worse, is arranged mainly due to the exceeded violation of industrial production
Put, arbitrarily the toppling over of town sewage and house refuse, the sewage irrigation in agricultural production and agricultural chemicals, the unreasonable use of chemical fertilizer
Etc. factor so that heavy metal contaminants enter in agricultural soil in several ways.And heavy metal has a difficult degradation, easily accumulated
Feature, the heavy metal being enriched in soil are not easy, with water leaching, to be not easy to be degraded by microorganisms, and can make with the absorption of root system of plant
With entering in crops body, growing for crop is influenceed, the underproduction of crop can be caused after accumulating to a certain extent, is had no harvest very
To death.More seriously, heavy metal can enter the combination such as human body, protein, organized enzyme with human body with food chain, make
It is distorted, and loses physiologically active, so that the symptoms such as chronic or acute poisoning occurs in human body, the health of human body is caused sternly
Endanger again, heavy metal pollution of soil problem turns into current environmental problem urgently to be resolved hurrily.
At present, the detection method of heavy metal mainly have mass spectrometry, atomic spectroscopy, UV-VIS spectrophotometry,
Electrochemical methods etc..Mass spectrometry is the side detected after the ion of motion is separated by karyoplasmic ratio with electric field and magnetic field
Method.Instrument cost height is disadvantageous in that, preprocessing process is cumbersome, and automation equipment is realized relatively difficult.Atomic spectroscopy energy
Content of beary metal in sample is effectively analyzed, but sample pre-treatments are complicated, analysis time length.Ultraviolet-ray visible absorbing point
Light photometry is to obtain monochromatic light and absorbing ability to test substance is measured using monochromators such as prism or gratings
Method, this method are limited in that interference caused by overlap of spectral lines and the triviality of operation.Electrochemical measuring technique is
Develop a kind of faster method in recent years, the test limit of electrochemical methods is relatively low, and measurement sensitivity is higher, be it is a kind of substantially
Environmentally safe green technology, receive the extensive attention of domestic and international researcher.But this method instrument is complicated, operating process
It is cumbersome, it is not suitable for live detection real-time.These traditional detection method complex operations, cost is high, every time can only
Detect one or more of constituent contents.
The minimizing technology of heavy metal mainly has elution method, electric heating repairing method, adds soil conditioner, pumps out processing in farmland
Method, biological restoration etc..Elution method is that the water that the water miscible chemical substance of heavy metal can be improved using washing lotion or addition is incited somebody to action
Pollutant is flushed to the outer layer of root.Elution method is relatively good for the highly polluted regulation effect of heavy metal, is relatively more suitable for light soil
Earth, but its investment is big, easily causes the nutrient loss and underground water pollution of soil.Electric heating repairing method is that soil is heated, and makes it
Heating parses noxious pollutant and unifies collection processing, is generally used for handling readily volatilized noxious pollutant, deficiency
Part is the organic matter and constitution water that this recovery technique can be destroyed in soil.Add soil conditioner method regulation effect and
Moderate cost, the soil for polluting less serious is applicable, but heavy metal is possible to meeting reactivation.It is a kind of suitable to pump out facture
The decontamination method on the spot polluted for deep subsoil or aquifer, is that inorganic agent is injected into soil from injection well, consolidates absorption
The pollutant being scheduled on soil particle parses and with treatment fluid to soil body low travel, then will by the pumped well of the other end
Treatment fluid containing pollutant, which pumps, to be handled, but processing procedure will consume substantial amounts of water, and the inorganic agent having also can in itself
Pollute.In addition, pumping out processing is difficult to ensure that pollutant and inorganic agent fully contact, it is also difficult to it is determined that the complete full journey of processing
Degree.Biological restoration using biotechnology come the soil of pollution administration, by biology come cut down heavy metal in purification soil or
Heavy metal toxicity is reduced, this method is easily operated, but biomass is low, selective to metal, and it is compound to be unsuitable for various metals
Contaminated soil.
Current heavy metal detection method and processing method is carried out separately, and is existed and is spent high, cumbersome, process
The problems such as complicated, the operating procedure or redundant and complicated of these operating methods, or disturbing factor are more, or need to use costly
Large-sized analytic instrument, and have very high professional skill requirement to operating personnel, can only mostly be completed in laboratory, it is impossible to
Meet scene, the technical requirements of quick online detection.
