Description
Technical field
The present invention relates to remediation of heavy metal-contaminated soil fields, are a kind of utilization nano carbon black package lime stone modifications
The method for repairing compound heavy-metal contaminated soil afterwards.
Background technology
With the development of the social economy, influence of the production and life of people to environment caused it is a series of global
Environmental problem, heavy metal pollution of soil is one of the ecological problem of wherein most serious.Cadmium (Cd) is that bio-toxicity is most in environment
One of strong heavy metal element, cadmium and its compound are classified as priority pollutant by Environmental Protection Agency (USEPA) and European Union.Cadmium is not
It is the indispensable element of plant growth, but in the presence of it is in the form of solution, is easy to be absorbed by plants and participate in necessary metabolism
Generate toxicity.A large amount of investigation and research has confirmed that cadmium is a kind of toxic dangerous substance, not only influences plant and also endangers people
Body and other animals.
Nano material has larger specific surface area and excellent photoelectric properties, and the application in terms of improving environment is increasingly
Extensively.Carbon black is the product of gaseous process, is that the volatile matter of organism or fossil feedstock turns in imperfect combustion or high temperature pyrolysis
Chemical conversion, the architectural characteristic with aromatic compound has relatively strong there are many oxygen-containing functional groups such as carboxyl, phenolic hydroxyl group, carbonyls
Slave environment in adsorbent ability.It goes to repair currently with the superpower adsorption capacity of nano carbon black this characteristic contaminated
Environment is in the exploratory stage.
It is not difficult to find out according in the national Survey of contaminating status bulletin of publication in 2014, Chinese soil environmental complex situation
Unsatisfactory, for the significant portion of arable land in the whole nation all by pollutions such as heavy metal and pesticides, this is serious to have threatened national " rice
The quality safety of sack " and " vegetable basket ".Soil current exceeding standard rate in China's is generally up to 16.1%, wherein the most serious
Based on pollution is polluted with inorganic type, secondly polluted for organic type.Since heavy metal is not degradable and is difficult to eliminate, so soil
In heavy metal once toxic action will be generated to plant-soil system to a certain extent by accumulating, so as to cause soil quality
Degeneration, crop yield and farming quality be greatly lowered, and deteriorate hydrological environment, with food chain present its by
The phenomenon that grade amplification, and then jeopardize health.
This research simulates heavy metal pollution paddy soils, research is not using heavy metal cadmium (Cd) contaminated soil as research object
Product after congener nano carbon black and lime stone package compounding is as a kind of compound stabilizer to being polluted by cadmium (Cd)
Paddy soil pollution is repaired.Experiment is continuously extracted by toxicity characteristic leaching procedure and Tessier forms, in identical pollution concentration
Heavy metal pollution soil regime under cadmium (Cd) stable case.Filter out stability preferably assemble stabilizer type and
The amount of application of stabilizer.Apply the variation of the physicochemical properties such as front and back soil pH value, organic matter by measuring stabilizer, analysis is steady
Influence of the agent to soil physico-chemical property is determined, to select the restorative procedure for being more suitable for heavy metal polluted soil of farmland.
Invention content
The present invention is directed to single stable agent remediating heavy metal (Cd) incomplete problem, it is proposed that assembling stabilizer can be more preferable
The compound pollution of reparation heavy metal soil.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
1. carrying out package to lime stone using nano carbon black compounds out a kind of stabilizer
2. the slaking reaction of contaminated soil
3. toxicity characteristic leaching procedure
4. form extraction experiment
5. soil pH measures
6. the measurement of the organic carbon content of soil
7. the measurement of content of soil available phosphor
8. the measurement of soil ammonium content
This research is based on the basis of the research of domestic and international correlation technique, with heavy metal (Cd) soil (4mg/kg) of pollution
For research object, filter out it is optimal assemble stabilizer scheme, and continuously carried using toxicity characteristic leaching procedure and five steps of Tessier
Experiment is taken, in conjunction with the variation compared before and after soil physico-chemical property, and according to the stabilization result for assembling stabilizer, is filtered out most suitable
The reparation of soil assembles stabilizer.This method is assembled using most common stabilizer lime stone with nano carbon black, not only
The drawbacks of single stable agent is for cadmium (Cd) contaminated soil is broken away from, while nano carbon black is also used as the modifying agent pair of soil
Contaminated agricultural soil is repaired；Relative to common stabilizer, the stabilizer that nano carbon black package lime stone assembles is repaiied
Multiple heavy metal soil is more excellent in physics and chemistry properties, the fertility and second ploughing possibility bigger of soil.For heavy metal cadmium
(Cd) coefficient of stabilization can reach 95% or more, effectively by Cd6+It is converted into Cd3+.15.5% soil fertilizer is improved simultaneously
Power is effectively increased soil charcoal library about 21.3%, and to using nano carbon black to wrap up the rice field of lime stone stabilizer, volume increase
17.1%.
