Description
Technical field
The invention belongs to underground water pollution processing unit fields, and in particular to a kind of full-automatic multi-layer runner processing underground water
Middle carbon tetrachloride device and its working method.
Background technology
Carbon tetrachloride(CCl4)It is a kind of organic chlorohydrocarbon of artificial synthesized low boiling point(Proportion 1.591g/cm3, boiling point 77
℃), it is slightly soluble in water.Foreign study shows:Carbon tetrachloride belongs to typical hepatotoxic agent, is influence maincenter first when high concentration
Nervous system then influences liver, kidney.It has persistence, extended residual and bioconcentration in the environment, therefore from 1979
Year has been included in " pollutant of priority acccess control in laboratory containing carbon tetrachloride " by U.S. EPA, has also been included in 68 kinds " in water by China
The pollutant of priority acccess control " list.
Eighties of last century the seventies cause in some regional laboratories due to largely manufacturing and using pesticide by four chlorinations
Carbon pollutes, as the water-bearing layer near the Michigan water-bearing layer in the U.S. and Canadian Ottawa is polluted by carbon tetrachloride
(It is mostly with nonaqueous phase in water-bearing layer(NAPL)In the presence of).
CCl in the municipal water supply for making Marina is polluted before the U.S. caused by the military bases Fortord Army4It is exceeded,
In August, 2000 measures CCl4Concentration is up to 15 μ g/L.Monitoring is found toxic in the laboratory discharge raffinate in the areas U.S. Livermore
The stacking of Harmful Waste leads to CCl4The generation of pollutant, CCl in noxious material percolate4At concentrations up to 500 μ g/L.2000
Year April, CCl in laboratory in the MW-10 wells near Hafner&Sons refuse landfills4Concentration is up to 6.3 μ g/L.
Existing Treatment process
Carbon tetrachloride is to common are machine pollutant, is easy to enter soil and water by eluviation with rainwater or irrigation water
Body causes the pollution of soil and water body.The current conventional method in relation to carbon tetrachloride raffinate pollution control in laboratory has following
It is several.
1. active carbon adsorption
With the carbon tetrachloride raffinate in activated carbon adsorption water source, without adding any chemical reagents, technology is of less demanding, low
Concentration adsorption effect is good, some, which are difficult to the substance degraded, to directly adsorb on activated carbon.By investigated activated carbon dosage,
Influence of the factors such as adsorption time, temperature to removal effect.
This method technical maturity, effect easy to operate is reliable, but adsorption efficiency is unstable, and carbon tetrachloride raffinate is in low concentration
Shi Xiaoguo is good, and when high concentration handles unstable, effectively adsorbs short life, and carrier needs to carry out secondary desorption that circulating could be carried out
With, and by the solution after solvent desorption, and the mixture containing carbon tetrachloride is formed, how to be isolated, is needed further again
Research.
2. in situ chemical oxidation method
Oxidant permanganate, Fenton reagent, hydrogen peroxide and the persulfate etc. that in-situ chemical recovery technique uses.
By oxidant injection containing a large amount of natural iron mineral, oxidation reaction can effectively repair organic dirt under the action of iron mineral is catalyzed
Contaminate object.Research shows that in-situ chemical recovery technique is easy that reparation area is made to generate mineralising, soil hardening, bad hydraulic permeability, changes and repair
Multiple plot structure.
3. biological restoration
Underground environment is reduced by the metabolism of biology using bio-inert and organic clay adsorbed bioactive bacterium
In poisonous and harmful compound engineering techniques, biology in situ repairing method can handle large-scale pollutant, and can be complete
Full decomposing pollutant.
Biology in situ method is an emerging technology for organic pollution source in treatment of laboratory at present, biological prosthetic
Key factor is suitable electron acceptor, and the oxygen receptor that has been best electricity, due to lack in the environment this electronics of oxygen by
Body, while the supply of microbial nutrition substance is insufficient, but also the biodegradation of microorganism cannot be lasting.
4. permeable reactive wall repairing method
Using the dependent response area filled with Active reaction medium material, when in contaminated laboratory by when, wherein
Polluter and reaction medium the effects that physics, chemistry and biology occurs and be degraded, adsorb, precipitate or remove, to make
Sewage is purified.
But permeable coefficient tensor, in the presence of being easily blocked, the native environmental conditions such as oxidation-reduction potential in laboratory are subject to
The shortcomings of destruction, operation and maintenance are relative complex, in addition bimetallic systems, nanotechnology cost are higher, these factors, which hinder, oozes
Permeability reaction wall further develops and widelys popularize.
