Description
Technical field
The invention belongs to organic contamination groundwater remediation fields, relate generally to a kind of reparation of trichloro ethylene polluted underground water
Method.
Background technique
Trichloro ethylene be commonly used for metal degreasing agent,Fungicide, refrigerant and clothesDry cleaning agent, year usage amount it is huge and
Increase year by year.Since trichloro ethylene is using the inappropriate processing of rear waste liquid and the leakage of some holding vessels, when trichloro ethylene pollutes
There is generation, seriously polluted soil and groundwater, becomes and be distributed one of widest pollutant in current environment.Trichloro ethylene is
A kind of noxious material, volatile and there are " three cause effect ", i.e., carcinogenic, teratogenesis, mutagenesis.In recent years a large number of studies show that they
It can cause the illnesss such as paralysis of trigeminal nerve, be listed in a kind of questionable person's class carcinogenic substance at present.So three in underground water and soil
The removal of vinyl chloride is particularly important.
Trichloro ethylene has the characteristics that viscosity is low, mobility is strong, once into soil and underground will be caused in environment
The pollution of water increases and repairs difficulty.At present the restorative procedure of trichloro ethylene polluted underground water mainly have chemistry redox technology,
Electrochemical techniques, bioremediation technology, hydrodynamic seepage pressure technology and ground pump-and-treat technology etc..Wherein it is used for in-situ chemical
The oxidant of oxidation mainly includes persulfate, potassium permanganate, Fenton reagent (Fe2++H2O2), ozone etc..Fenton technology is because of it
Most of organic matters can be aoxidized, and efficiency is higher and be concerned, but hydrogen peroxide easily decompose under conditions of neutral ph by disproportionation
Failure and high-strength hydrogen peroxide oxidation of organic compounds while, can generate the gentle body of big calorimetric, this may cause underground collapse,
Omnicide is even exploded.
Persulfate can generate SO by activation methods such as heat, alkali, transition metal4And OH, to have in water of degrading
Machine pollutant.However the temperature in underground water is generally 15 DEG C or so, persulfate is not reacted with pollutant at this temperature, if
The temperature of underground water is improved with modes such as heating, rehabilitation cost will be very high.Underground water in neutral pH environment is by adding
Enter Fe2+/Fe3+Or add the same treatment effect of activation method of alkali bad or underground environment is caused to seriously affect, destroy ecological ring
Border.
Calper calcium peroxide is gradually applied to the repairing and treating of polluted underground water because of its controllable-rate for decomposing generation hydrogen peroxide,
Oxygen can also be generated simultaneously, facilitate the oxidative degradation of aerobic microbiological, as a kind of Green Oxidant, application increasingly by
To attention.Patent No.: 201410561933.8, invention and created name is that " a kind of persulfate-calper calcium peroxide dual oxidants are gone
Except the method for multiring aromatic hydrocarbon substance methyl naphthalene " Chinese patent disclose multiring aromatic hydrocarbon substance methyl in a kind of removal water body
The method of naphthalene, has main steps that into the water body containing methyl naphthalene, and persulfate and calper calcium peroxide is added, stirs evenly, and ties up
System pH is held to react 4-5 days under the conditions of neutral slant acidity, it can oxidation removal polluter.The method that the innovation and creation provide
Oxidability is stronger, but practical groundwater environment complexity (such as HCO3 -、CO3 2-、Cl-Plasma interference, Some Organic Pollutants are same
When be present in underground environment) or groundwater pollutant concentration it is higher (such as pollution source area, concentration over-standard hundreds times), therefore often need
Want the calper calcium peroxide and persulfate additional amount of higher concentration.And underground water is because its buffer capacity is poor compared with soil, calper calcium peroxide
The quick raising for easily causing underground environment pH value largely is added, underground water is caused to alkalize, destroys underground environment, while can also make
Become extremely faint (calper calcium peroxide mainly generates oxygen under alkaline environment) at the significant wastage or even oxidability of medicament,
Practical polluted underground water repairing effect is bad.In addition, technical grade calper calcium peroxide (content 60%) powder contain calcium hydroxide at
Point, be dissolved in water will generate more calcium hydroxides (calcium hydroxide and calper calcium peroxide contained in itself be dissolved in water generation hydrogen-oxygen
Change calcium), after technical grade calper calcium peroxide used is dissolved in water in live practical application, pH rises faster, influences more caused by environment
Greatly.
CaO2After contacting with water, there are following two isolations:
CaO2+H2O→Ca(OH)2↓+1/2O2↑ (1)
CaO2+2H2O→Ca(OH)2↓+H2O2(2)
Above-mentioned patent additionally provides dual oxidants and plays a role optimal pH condition as neutral slant acidity, and acid used in regulating system is
Nitric acid.Nitric acid is strong acid, has corrosivity, easily makes quick-fried, highly acid and unstability, and misoperation easily causes harm, such as inhales
Acute poisoning, serious person's shock, asphyxia etc. can be caused by entering nitric acid smog.And after calper calcium peroxide is added, as calper calcium peroxide is continuous
Dissolution, calcium hydroxide persistently generate, and maintain the underground environment of neutral slant acidity that will be continuously added nitric acid, technique is cumbersome and best
PH condition is not easy to control, bad in practical polluted underground water repairing effect, or even as the restriction step of in-situ chemical reparation.
Summary of the invention
