Description
Technical field
The present invention relates to field of environmental improvement, the restorative procedure of benzyl chloride contaminated soil a kind of is specifically related to and special
Water-locator.
Background technology
Benzyl chloride is a kind of important organic synthesis intermediate, belongs to halogenation benzyl class irritant compound, on agricultural chemicals, it
Organophosphorus fungicide kitazine, different rice blast net not only can be directly synthesized, and the important of other many intermediates can be used as
Raw material, such as synthesize benzene acetonitrile, chlorobenzoyl chloride, 3-phenoxy-benzaldehyde, in addition, benzyl chloride medicine, spices, color additive,
All it is widely used in terms of synthetic resin, it is a kind of important chemical industry, medicine production intermediate.So enterprise was producing
All unavoidably contain substantial amounts of benzyl chloride intermediate in waste liquid or discarded object produced by journey.Benzyl chloride has in itself urges
Tear, high poison belongs to carcinogen, and with environmental persistence, because benzyl chloride is wide using scope in itself, usage amount than larger,
Benzyl chloride is leaked in transportation, or the giving up containing benzyl chloride brought in process of production by each manufacturing enterprise
Liquid or discarded object are directly abandoned, or are leaked in process of production, can all be directly resulted in benzyl chloride and be entered soil, finally
Contaminated soil.Temporarily also reported for how benzyl chloride contaminated soil repairs disposal without any method.
The content of the invention
The main object of the present invention is to provide the restorative procedure and special water-locator of a kind of benzyl chloride contaminated soil.The party
Method may be such that benzyl chloride contaminated soil is able to repair the effect for reaching and reclaiming.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is：A kind of benzyl chloride contaminated soil is repaiied
Compound method, comprises the following steps：
(1) benzyl chloride content in benzyl chloride contaminated soil is surveyed；
(2) potassium permanganate-nitric acid combination solution is configured；
(3) by it is above-mentioned match somebody with somebody solution add benzyl chloride contaminated soil in fully react.
In addition, for the special water-locator of above benzyl chloride contaminated soil remediation, it is characterised in that：Described water-locator is
The tapered body in one end, the body portion close to taper one end is exported provided with compositional liquor.
Implement soil remediation according to technical scheme, compositional liquor is added using water-locator and repaired in soil
Reaction, reaction terminate after through detecting that benzyl chloride is fallen by basic handling in soil, what is finally given a series of does not endanger to soil
Harmful material, such as manganese dioxide, potassium nitrate, Potassium Benzoate.The soil remediation method of disposal environment-friendly high-efficiency.
Brief description of the drawings
Fig. 1 is that water-locator of the present invention uses schematic diagram.
Embodiment
A kind of restorative procedure of benzyl chloride contaminated soil, including step：(1) benzyl chloride in benzyl chloride contaminated soil is surveyed to contain
Amount；(2) potassium permanganate-nitric acid combination solution is configured；(3) by it is above-mentioned match somebody with somebody solution add it is fully anti-in benzyl chloride contaminated soil
Should.Reaction terminates, and soil is typically in faintly acid, and pH value meets about in 6-7《Standard of soil environment quality GB15618-1995》.
Take a certain amount of benzyl chloride contaminated soil to be placed in reaction vessel, soil is implemented after repairing using above technical scheme, after testing
Benzyl chloride is fallen by basic handling in soil, a series of material being safe from harm to soil finally given, such as manganese dioxide, nitre
Sour potassium, Potassium Benzoate etc..It is well known that Mn is the abundant element of reserves, MnO in the earth's crust2It is naturally occurring in soil, KNO3It is
Very good compound fertilizer, Potassium Benzoate is that food additives are innocuous substance, can increase the nutrition of soil.Therefore
Acid potassium permanganate reparation disposal benzyl chloride contaminated soil is introduced into soil does not have environmental risk.That is this method will
Soil is converted into nontoxic, and environment-friendly high-efficiency from poisonous.Experiment of reclaiming, such as cultivation bracketplant are carried out repairing the soil after finishing,
Plant grows fine, it was demonstrated that the soil after reparation possesses the condition of reclaiming.
Further specifically scheme is, the quality of potassium permanganate and nitric acid in described potassium permanganate-nitric acid combination solution
Than for 6-14.The mass concentration of nitric acid product used herein above in itself is 65%.The acidity value of the specific combination solution can be with
Determined according to the situation of benzyl chloride soil to be disposed, benzyl chloride is disposed to consume and is defined in final soil.
Wherein, solution is to be added to by water-locator in benzyl chloride soil in described step (3), described water-locator
Outlet is located at the lower position in soil.Here water-locator is substantially a pipe, and the pipe end is from body to termination
Portion's diameter is tapered into and tapered, provided with compositional liquor outlet on the body at neighbouring conical end portion position, when specifically used
Soil bottom is inserted in the end of taper, and compositional liquor outlet is also corresponded in soil lower position, and now compositional liquor is by described
Outlet enter soil, as compositional liquor is continuously added into, compounding liquid measure increase, compositional liquor is in soil little by little by bottom up
Through soil surface is overflowed in portion, so as to be impregnated with whole soil, because the density of benzyl chloride is larger, can typically fall in soil lower floor,
So being inserted using water-locator in benzyl chloride contaminated soil so that polluted when acid permanganate soln is added from benzyl chloride
Soil bottom is up impregnated with, so that potassium permanganate-nitric acid combination solution is fully contacted with benzyl chloride soil, is reached fully anti-
Answer the purpose of rehabilitating soil.
The reaction time is 10-15 days in described step (3), and reaction temperature is room temperature.After reaction terminates, soil is without obvious
Smell, detection potassium permanganate residual quantity is less than 10mg/kg；Benzyl chloride residual quantity is less than 15mg/kg, and repairing effect is fine.
It may be noted that reaction is carried out in a reservoir in described step (3).That is, being chlorinated benzyl pollution
Soil is usually, from disposal center is impurely transported back, to be subsequently placed in it in a container isolated with ambient soil and repaired
Disposal, on the one hand if in impurely reparation disposal needs to build divider wall on the spot, scene also needs to put into substantial amounts of people
Power and material resources, are repaired, then to unpolluted soil during reparation on the spot if not building divider wall in addition
Which type of harm can or can not be also brought not can determine that.Transport contaminated soil back processing center and carry out reparation again and avoid repairing
The secondary injury that may be brought during multiple to environment, while such repair is also more cost-effective.
For above restorative procedure, it is also a kind of exclusively with water-locator, described water-locator 10 is tapered for one end
Body, close to taper one end 11 body portion provided with compositional liquor outlet 12.Conical end portion is easier to water-locator inserting soil
Earth bottom, had also illustrated particularly with regard to its application method of water-locator 10 and before acting on, had just repeated no more here.
More specifically described body is pipe, and described taper one end 11 is coniform, and described compositional liquor goes out
Mouth 12 is located on the pipe body of pipe and the junction of taper one end 11.The water distributor structure of certain pipe is more simple, uses
Also it is more convenient.
