Description

Mercury contaminated soil repair materials
Technical field
The invention belongs to technical field of soil remediation, be specifically related to a kind of mercury contaminated soil repair materials.
Background technology
Along with the fast development of modern industry, mercury pollution problem is the most serious, 50 to the seventies of eighties of last century, passes through " minamata disease " event of Japan, people come to realise hydrargyrum can produce serious harm in water system.The research of Sweden's water environment Also indicating that, in fresh-water fishes, saltwater fish and other aquatic organism, the content of mercury compound is the highest.Field, Song Hua River, China northeast, is subject to The waste water discharged to littoral chemical plant, Metallurgical Factory causes mercury pollution, makes fisherman deeply hurt, through dead fisherman's postmortem is found, The multiple organ of its health all has hydrargyrum and the methyl mercury of excess.Originally people only focus in water body mercury pollution research, and for The work that hydrargyrum in soil is done is the most few.In recent years, it has been found that in remote lake, the mercury content of fish raises is by Mercury In The Air Causing through long range propagation and sedimentation, the Researches on Biogeochemical Circulation of Mercury In The Air and hydrargyrum is just increasingly becoming mercury pollution research One of focus.Mercury In The Air can enter soil by dried wet deposition, and the hydrargyrum in soil passes through the physics of complexity, chemical reaction, Major part is stranded in soil with various forms, and part is absorbed by plants, and fraction is under certain condition with the form of gaseous mercury Discharge into the atmosphere, it is seen that soil is the remittance of hydrargyrum, be again the source of hydrargyrum.It plays important work in the biogeochemical cycle of hydrargyrum With.Therefore, Soil Mercury Pollution research received much concern in the last few years, made progress in many aspects.
Being widely present in rock, water, air and biosphere that hydrargyrum is depended on for existence people, hydrargyrum is background values in natural environment Different.Since 19th century, along with industrial expansion, the purposes of hydrargyrum gets more and more, and there is a sharp increase in output for hydrargyrum, so that substantial amounts of hydrargyrum enters Enter environment.The mercury quantity that utilization is exploited in the current whole world every year is about more than 10,000 tons, and wherein most regions becomes three wastes entrance ring Border, such as, often produces 1 ton of chlorine, with regard to 100-200 gram of hydrargyrum of loss in chlorine industry；Produce 10,000 tons of acetaldehyde and just have 500-1500 gram Hydrargyrum enters environment.In gold mining industry, put forward, with hydrargyrum, the technique that gold is cheap and simple, but also result in substantial amounts of mercury pollution environment.Coal In hydrargyrum make hydrargyrum concentration in air also be greatly increased, the soil near power plant, the content of Mercury in Water Body increase the most therewith.Cause This, in agricultural product, mercury content also increases, and in daily life, the hydrargyrum in a large amount of discarded daylight lamp and battery also pollutes environment.Its It as mineral reserve exploitation smelt, the eruption in volcano, be all hydrargyrum in environment weight source, and in soil hydrargyrum source mainly have with Under several aspects:
Parent soil material, the hydrargyrum in parent soil material is source most basic in soil, the content of mercury element in protogine, directly Decide the mercury content in soil, there is the biggest difference, adds people in certain Different parent materials, its content of soil of rock formation The impact of class production activity, the Mercury in Soil content obtained under the conditions of various often has bigger difference, and is difficult to determine that it comes Source.
Atmospheric sedimentation, research in the last few years shows, atmospheric sedimentation is the important sources of Mercury in Soil.Mercury In The Air enters soil After, because of soil CLAY MINERALS AND THEIR SIGNIFICANCE and organic adsorption, the overwhelming majority by soil sticking or fixing, is enriched in soil rapidly Top layer, causes the rising of Mercury in Soil concentration.
Directly polluting, hydrargyrum is directly entered the approach of soil and mainly includes the heap of commercial production waste material and domestic waste Put, irrational in agricultural tilling use mercurous fertilizer and pesticide and irrigation etc..
The recovery technique of mercury contaminated soil mainly has following several approach:
1 physical chemistry reparation:
Soil moved in improve the original method refers to substantial amounts of unpolluted clean soil on contaminated soil surface covers again, and this is to administer The method that contaminated soil is the most traditional, although this method can make hydrargyrum concentration be reduced to below marginal value, is reducing mercury in soils Content aspect has reasonable effect, but this method input cost is bigger, is not suitable for carrying out popularization and application widely.
2 Thermal desorption methods
Owing to hydrargyrum has low-steam pressure, volatile characteristic, based on this characteristic, soil can be carried out heat treated, So that the hydrargyrum in soil becomes gaseous state, then by the gas condensation of desorption, then by its centralized recovery, and subsequently through harmless Change processes the purpose reducing mercury in soils content.
3 curing/stabilizing reparations
Curing/stabilizing technology refers to prevent or reduce contaminated soil release harmful chemical and pass through physics With the recovery technique combination that chemical action fixes pollutant in soil, this technology is generally used for heavy metal and radioactive substance is dirty The harmless treatment of dye soil.Result shows, in the leachate after disposal of stability, the concentration of hydrargyrum basically reaches or close to danger The judging standard value of evil refuse Leaching.Compared to other technology, this technical costs is low, processes required time short, Er Qieju Sex-limited little, applied widely.
4 electromotion repairing technique
Technology of Electrodynamics Renovation is primarily adapted for use in hypotonic soil, for majority of organic pollutants, or is used for radiating Property material and the stronger organic improvement of adsorptivity, experimental results demonstrate, the metals such as chromium, hydrargyrum, lead, zinc are gone by technique Except rate is up to more than 90%.Compared to other method, this technical costs is cheap, simple to operate, and efficiency is higher, at heavy metal-polluted soil In-situ immobilization aspect has a biggest advantage, and during need not the effect of chemical agent, environment is caused hardly any Negative impact.But the shortcoming of this method is, when Organic substance dense for water-insoluble liquid processes, often send out Raw obstructing problem.
5 leaching methods, soil eluviation method is to utilize leacheate that the heavy metal in solid phase of soil is transferred in liquid phase of soil, then The soil remediation method that waste water rich in heavy metal is recycled further.More for the leacheate of washed off soil, including Inorganic solution abluent, organic acid and salt abluent, chelating agen and surfactant etc., the method easily produces new dirt Dye.
Using modifying agent, chemical redemption is exactly input modifying agent in soil, by the absorption of heavy metal, oxidation also Former, antagonism, to reduce the biological effectiveness of heavy metal.Conventional modifying agent has Calx, zeolite, calcium carbonate, phosphate, silicon Hydrochlorate and the organic substance of promotion reduction.The method is a kind of in-situ remediation method, and heavy metal still remains in soil, easily Reactivation harm plant, its potential threat does not eliminate.
6 phytoremediation, its mechanism is mainly by the absorption of certain plants heavy metal element, accumulates and convert, reaches Alleviating the purpose of heavy-metal contaminated soil, compared with traditional restorative procedure, it is excellent that phytoremediation has green, environmental protection, economic dispatch Gesture, plant is removed the heavy metal in soil and mainly relies on plant extraction effect, root system filtration, phytovolatilization effect and plant Thing immobilization role.
7 microorganism remediation, soil microorganism includes the free microorganism relevant to plant root, symbiosis rhizosphere bacteria, bacterium Mycorrhiza fungi, microorganism gradually forms the population of some heavy metal resistances in Heavy-metal Polluted Environment, and they are solved by biology Poison heavy metal produces resistance, it is possible to survive in gold metallic pollution environment.
8 animals are repaired, and utilize some lower animal such as Lumbricus in soil can absorb the characteristic of heavy metal, to a certain degree Heavy metal ratio in upper reduction contaminated soil, reaches the purpose of animal restoration of soil polluted by heavy metal.
9 Agro-ecology reclamation activitiess
In recent years, a series of Agro-ecology reclamation activities is gradually applied to the reparation of mercury contaminated soil, and agricultural is raw State reparation is based on phytoremediation, by the control of soil environment and two aspects of plant is improved remediation efficiency, Soil environment aspect, is increase soil fertility by application of organic fertilizers, weakens the toxicity of heavy metal in soil, reduces plant Poison, or improved the biological effectiveness of heavy metal by organic fertilizer, be beneficial to the absorption of rehabilitation plant, improve remediation efficiency. In terms of plant, by plant cultivation and domestication, strengthen patience and the cumulative percentage of plant heavy metal, improve the reparation effect of plant Rate.It addition, by regulating the ecological factors such as such as soil moisture, soil, pH, soil redox status and gas epidemic disaster, profit Surrounding medium is controlled, to weaken the murder by poisoning of heavy metal on plants by ecological means.
Above-mentioned to the restorative procedure by heavy-metal contaminated soil, or the huge sum of money in soil can not be eliminated the most thoroughly Belong to particularly hydrargyrum, or bring new pollutant, there is various defect, accordingly, it would be desirable to for above-mentioned present situation, grope a kind of removal Hydrargyrum effective and relatively mild do not produce new contaminated soil renovation agent.
