Description
Technical field
The invention belongs to underground water pollution processing unit fields, and in particular to four in a kind of spiral-flow aeration method processing underground water
Chlorination carbon device.
Background technique
Carbon tetrachloride is colourless liquid, 132.2 DEG C of boiling point.Mainly for the production of military explosive during the World War I
Required picric acid.To production DDT (DDT) insecticide between nineteen sixty, is largely used to, after nineteen sixty, DDT is gradually within 1940
Replaced other pesticides of efficient low residual hazard, the demand of carbon tetrachloride declines increasingly, is mainly used as ethyl cellulose and is permitted
The solvent of more resins produces various other benzenes intermediates, such as nitro carbon tetrachloride.
Carbon tetrachloride Central nervous system has inhibition and anesthetic effect；It is irritant to skin and mucous membrane.
Acute poisoning：Contact high concentration can cause to anaesthetize symptom, or even stupor.It is detached from scene, it, can be very fast actively after treatment
Restore, but still there are the symptoms such as headache, dizziness, inability, appetite stimulator in a few days, liquid has slight stimulation to skin, but repeatedly
Contact then plays erythema or has the shallow property necrosis of slight table.
Slow poisoning：Often there is ophthalmodynia, sheds tears, conjunctival congestion；There are the neurasthenia such as headache, insomnia, failure of memory in early stage
Symptom；Severe one causes toxic hepatitis, and kidney damage can occur individually.
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 underground water 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, technical requirements are not high, low
Concentration adsorption effect is good, and some substances for being difficult to degrade can directly adsorb on active carbon.By investigated active carbon dosage,
Influence of the factors such as adsorption time, temperature to removal effect.
This method technique is disadvantageous in that adsorption efficiency is unstable, and effect is good when carbon tetrachloride raffinate is in low concentration,
It handles unstable when high concentration, effectively adsorbs that the service life is short, and carrier needs to carry out secondary desorption just can be carried out circulation utilization, and pass through
Solution after solvent desorption, and form the mixture of the dichloropropane Han 1,2-.
2. 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 is capable of handling 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.Therefore, disadvantage is that, in the environment
Lack this electron acceptor of oxygen, while the supply of microbial nutrition substance is insufficient, but also the biodegrade of microorganism cannot be held
Long.
3. permeable reactive wall repairing method
Using the dependent response area for being filled with Active reaction medium material, when passing through in contaminated laboratory, wherein
Polluter and reaction medium the effects of physics, chemistry and biology occurs and be degraded, adsorb, precipitate or remove, to make
Sewage is purified.
It is easily blocked disadvantage is that permeable coefficient tensor exists, oxidation-reduction potential in laboratory etc. is natural
The disadvantages of environmental condition easily goes to pot, and operation and maintenance are relative complex, in addition bimetallic systems, nanotechnology higher cost, these
Factor hinders further developing and wideling popularize for permeable coefficient tensor.
