Description
Technical field
The invention relates to a kind of latex composition and its manufacture method, especially with regard to one kind for containing
The latex composition and its manufacture method of chlorine organic pollution control.
Background technology
Soil is particularly important in the Sustainable Development of environmental resource and utilization with the prevention and cure of pollution of underground water
One ring.Expansion is polluted and continues when environment is subjected to, it will the environment for jeopardizing our lives is even broken
Bad natural, ecological etc..In recent years due to rapid industrial development, chloride aliphatic hydrocarbon
(chlorinated aliphatic hydrocarbons, CAHs) have to fat Class dissolving power high, it is low it is flammable,
The characteristic such as low boiling and vapour pressure high, therefore largely it is widely used in industrial metal and electronic component
The operations such as cleaning, degreasing, surface mount and dry-cleaning, but because its proportion is more than water, solubility is also relatively low,
Also referred to as heavy nonaqueous phase liquid (dense non-aqueous phase liquid, DNAPL), its with
Trichloro ethylene (trichloroethylene, TCE) and tetrachloro-ethylene (terachloroethylene, PCE)
Most commonly seen, it causes native water severe contamination and is difficult the problems such as renovating, and is that many researchs continue not in recent years
The disconnected target made great efforts.
Under the principle of green regulation (green remediation), the investigation of pollued field and Renovation and planning
There must be the thinkings different with tradition.Scholar uses anaerobic organism remedial technology now
(bioremediation) case for processing contaminated site is very universal, educated again using natural biology as
The preferential selection of regulation, is also green regulation concept and the target friendly to environment.Although biology educates journey again
The W-response speed of sequence is relatively low, but on long terms, biology educates smaller to the destructiveness of site again, relatively accords with
Close the demand of " educating again ".It is upper in now application, because the W-response speed of Natural Attenuation is relatively low, because
This heavier-duty biology educates technology attention again, and it is to be changed the biological technology of educating again that heavier-duty biology is educated again
Kind, reinforcing, its reaction rate is more together in the demand of engineering.Therefore, under proper condition in order to accelerate
Biological decomposition speed, major part is to add during nutrition comes from body of groundwater, produce underground water enough
Hydrogen and low-molecular-weight fatty acid, thereby provide carbon source and improve the ability of anaerobic biological decomposition, to process
Contaminated soil and underground water, this Class nutrient source have soluble, low stickiness, solid-state and various examination
The characteristics such as the property tested.
The mode of often See reinforcements biological decomposition is broadly divided at present：(1) nutritive salt of bioerodible is added
Or electron acceptors are in microorganism group existing in pollued field, activation site；(2) in pollued field
Directly addition has the special strain of capacity of decomposition to pollutant, or utilizes technique for gene engineering, development tool
The genetically modified microorganism of specific pollutants capacity of decomposition；(3) using biological treatment by pollutant through ventilation or
Special bioreactor or Sheng Wu Filter, zinc cation tower removal pollutant are delivered to after soil washing, or
It is using ground till, compost treatment.
When the reduction dechlorination of different phase is produced, reaction generates energy may be then utilized by the microorganism,
And promote growth of microorganism can effective degradation of contaminant efficiency.The microorganism for having many has been found to,
Electronics can carry out dechlorination in the case of providing, and such as produce ethene dehalogenation and intend coccus (Dehalococcoides
Ethenogenes) by the use of H2 as electronics supplier, Dehalococcoides ethenogenes and one kind
Dehalogenation bacillus (Dehalobacter restrictus) can obtain energy by dechlorination respiration；Separately there is methane
Generation bacterium (methanogenic producing microorganisms), acetic acid generation bacterium (acetogenic
Producing microorganisms) and sulfate reducing bacteria (sulfate-reducing microorganisms)
Deng can also be degraded TCE in Co metabolism mode.
Even if converted in biology however, there is many microorganisms dechlorination can be carried out under anaerobic environment
Cheng Zhong, vinyl chloride (vinyl chloride, VC) is relatively slow by the process that Co metabolism is converted into ethene,
And act on typically incomplete, therefore the accumulation of VC is easily caused, and VC is known carcinogen.
Such as Dehalococcoides sp.strain FL2 reduction dechlorinations metabolism TCE in Dehalococcoides strains
It is converted into VC；Other strain CBDB1 (Ernest et al., 2013), strain BAV1 (et al.,
2013) and the bacterial strain such as strain GT (Chambonet al., 2013) all there is document to confirm can be by PCE and TCE
Reduction dechlorination forms VC.However, only belong to Dehalococcoides ethenogenes, strain 195,
The bacterial strains such as BAV1 and GT can by the complete dechlorinations of VC into ethene harmless products.
Existing many kinds of nutrient matrixes are widely used in existing ground anaerobic biodegradation technology, such as candy Class at present
(molasses), organic acid (lactate, formates, butyric acid salt, propionate and benzoate), alcohol Class (methyl alcohol
And ethanol) and yeast extract, can improve degradation efficiency.But these nutrient matrixes must have high dissolving
Property and Biodegradable high, and need to often add supplement to promote the growth of microorganism.Additionally, injection
Nutrient matrix can cause the problems such as underground water blockage and acidifying, and sulfate reduction produces sulfide
