Description
Technical field
The present invention relates to soil remediation, more particularly to a kind of soil in-situ repair composite material efficiently removing removing heavy metals.
Background technology
Soil is the most active ring layer of earth surface system, is the foundation stone that the mankind depend on for existence and development, is to ensure the mankind
The important substance of food and ecological environment security basis.With the modernization of industrial development and agricultural production, the huge sum of money in soil
Belong to pollution and has become one of the main problem for endangering global environment quality.Heavy metal element is a kind of potential pollution
Object, once entering in soil, is administered very difficult it is difficult to by soil microbial degradation.Heavy metal pollution of soil is main
From industrial production, agricultural production and communications and transportation.They not only result in soil vitality and decline and make grain drop in production, and
And in plant and power cylinder accumulation and food chain can be entered, endanger human health.More seriously, these pollutions have
The features such as chronicity, concealment and irreversibility.Heavy metal-polluted soil recovery technique is mainly showering, stabilization both at home and abroad at present
Change processing and heat treatment etc..Soil heterotopic rehabilitation cost is high, and soil heat treatment, chemical leaching and stabilization technology lead to soil
The ecological functions of this tool are lost, the problems such as plant disposition of phytoremediation for soil technology restrict heavy-metal contaminated soil
Reparation process.Above-mentioned technology is undoubtedly " palliative treatment " of soil remediation, and the reason of why taking these technologies is soil
The permanently removal of middle heavy metal is the technical bottleneck of soil remediation and the problem that needs are broken through.Economically feasible, does not influence technically reliable
It is government, farmer and the numerous people that grain-production, the heavy metal for not destroying farmland quality, which permanently remove soil in-situ recovery technique,
Many active demands.
At present in relation to can permanently remove heavy metal in agricultural land soil and not destroy the technical patent of soil texture fertility also
It is less.The Chinese patent of Publication No. CN103752597A discloses a kind of utilization fixative synergy heat treatment heavy metal in soil
Method, this method fixed efficiency is high, is suitable for the reparation that factory and enterprise moves ground heavy-metal contaminated soil, but the height of this method
Warm processing needs to consume the more energy, secondary pollution is also easy to produce in processing procedure, heavy metal can evaporate again.It is open
Number for CN102657926A Chinese patent disclose a heavy metal species normal temperature cure agent and use its curing heavy metal pollutant
The method of middle heavy metal, the heavy metal normal temperature cure agent are composed of the following components by weight percentage：Magnesia 30.0%-
40.0%, potassium dihydrogen phosphate 55.0%-65.0%, borax 3.5%-5.0%, iron oxide 0.1%-0.5%, silica
0.1% -0.54%, the solidification effect of the normal temperature cure agent is good, and at low cost, operating process is simple and practicable, but this method be with
After adding stabilizer, forms insoluble or sl. sol. heavy metal precipitation form and exist, when external environment changes, heavy metal ion
It is easy anti-molten.The Chinese patent of Publication No. CN104959379A discloses a kind of method of restoration of soil polluted by heavy metal,
Rehabilitation plant is planted in soil and soil is applied and repairs biological agent, and this method is of low cost, implements simple, practicability
By force, it can be carried out at the same time the processing of a variety of pollution mixed compounds, it is environmentally safe, and do not stay secondary pollution and any environment hidden
Suffer from, generating a large amount of biomass in repair process can be used as animal feed and biomass energy, make soil remediation process economy that can hold
It is continuous.But the rehabilitation plant described in this method is annual crop, the period is longer, and repair time is in relatively slow.
Invention content
In view of this, the purpose of the present invention is to provide a kind of soil in-situs efficiently removing removing heavy metals to repair composite wood
Material, can repair each heavy metal species (such as Pb, Cd, Cu, Zn, Cr, As) and toxic organic compound (such as chlorinatedorganic, bromo organic matter,
Antibiotic etc.) contaminated soil, the form that heavy metal in soil activity is strong and bioavailability is strong is reduced, prevents heavy metal from soil
Earth Transport And Transformation prevents the biological concentration and amplification of heavy metal to plant, can efficiently remove the heavy metals such as chromium, the mercury in soil,
Restore the original function of soil, meet agricultural development needs, ensures the ecological safety of the plants such as crops, to avoid heavy metal
Biomagnification and the ecological risk that is brought to the people of enrichment.
The soil in-situ repair composite material for efficiently removing removing heavy metals of the present invention, the composite material raw material is by weight
Including following components：
10-20 parts of sodium peroxydisulfates, 5-10 parts of polyepoxy sodium succinates, 1-5 parts of polyvinylpyrrolidones, 1-3 parts of nano-sized carbon,

Solid-to-liquid ratio is sufficiently stirred mixing, stands at room temperature for 24 hours；
B. it is drying at 80-90 DEG C in temperature by the feed liquid impregnated, is dried to moisture content < 15%, then puts it into
It is connected in the tube furnace of nitrogen, rises to 500-600 DEG C of activation temperature from room temperature with the heating rate of 10 DEG C/min, then constant temperature
1-1.5 hour；
C. it after activated sample being cooled down, with the HCl solution pickling of a concentration of 3mol/L, after impregnating 30-40min, uses
Temperature is that 70 DEG C~80 DEG C of distilled water washs repeatedly, until pH value is in neutral range；
D. the sample washed is put into drying box, is to dry postcooling at 110-120 DEG C and grind in temperature
It is 200-250 mesh to grain size；
Further, the composite material raw material includes following components by weight：

Further, the surfactant is the mixed of laruyl alcohol sulfosuccinate disodium and sulfosuccinic acid dihexyl sodium
Close object；
Further, in step a, the activator is the liquor zinci chloridi of a concentration of 3mol/L, solid-to-liquid ratio 1： 2；
Further, the Chinese medicine slag be Radix Ophiopogonis, Radix Glycyrrhizae, Radix Isatidis mixture.
Beneficial effects of the present invention：The soil in-situ repair composite material for efficiently removing removing heavy metals of the present invention, passes through two
Heavy metal is effectively fixed in the components such as thiocarbamic acid chitosan, passes through nano-sized carbon, serpentine and Lignitic Humic Acid, Chinese medicine slag
Etc. other components directly with heavy metal lead, cadmium and nitrogen ion occur chemistry, physical absorption, reduce available heavy metal content,
Slow down Nitrogen releasing, improve nitrogen utilization efficiency, reduces the form that heavy metal in soil activity is strong and bioavailability is strong, resistance
Only heavy metal is transformed into plant from soil mobility, prevents from the biological concentration of heavy metal and amplify and mitigate to be grown in contaminated soil
Plant in Cadmium accumulation, can repair and repair each heavy metal species (such as Pb, Cd, Cu, Zn, Cr, As) and toxic organic compound (such as chloro
Organic matter, bromo organic matter, antibiotic etc.) contaminated soil, the heavy metals such as chromium, the mercury in soil can be efficiently removed, soil is restored
Function originally meets agricultural development needs, ensures the ecological safety of the plants such as crops, to avoid the biology of heavy metal from putting
The ecological risk that big and enrichment is brought to the people.
