Description
Technical field
The utility model belongs to environmental protection treatment technology, relates to the process field containing chlorobenzene underground water, particularly remains the tripping device of chlorobenzene in underground water.
Background technology
Chlorobenzene, has another name called monochloro-benzene.Molecular formula: C
6h
5cl.The hydrogen being benzene, by the compound formed after the replacement of chlorine atom, is colourless transparent liquid, has the smell of similar almond.Volatile.Be dissolved in most of organic solvents such as ethanol, ether, chloroform, benzene, water insoluble.Inflammable, steam and air form explosive mixture, limits of explosion 1.3%-7.1% (vol).Impact not by air, moisture and light under normal temperature, then dechlorination of seething with excitement for a long time.Steam sloughs hydrogen and hydrogenchloride through red heat pipe, generates diphenyl compounds.Poisonous.There is accumulation in vivo, undermine liver, kidney and other organs.To skin and mucous membrane irritant.Narcoticness is had, LD to neural system
502910mg/kg, maximum allowable concentration 50mg/m in air
3.Mainly for the production of sterilant, also can be used as the raw material producing phenol, nitro-chlorobenzene, phenyl ether, the materials such as further synthetic dyestuff, rubber.In organic synthesis and industrial production, chlorobenzene is used as high boiling solvent.
Health hazard: have suppression and anesthetic action to central nervous system; To skin and mucous membrane irritant.Acute poisoning: contact high density can cause anesthesia symptom, even goes into a coma.Depart from on-the-spot, actively after treatment, can comparatively fast recover, but in a few days, still have the symptoms such as headache, dizziness, unable, appetite stimulator.Liquid has slight pungency to skin, but repeatedly contacts, then play erythema or have the shallow property of slight table downright bad.Chronic poisoning: often have ophthalmodynia, shed tears, conjunctival congestion; There are the neurasthenia symptoms such as headache, insomnia, hypomnesis in early days; Severe one causes toxic hepatitis, kidney damage can occur individually.
Aeration zone is the important channel connecting surface soil and waterbearing stratum, plays certain " barrier " effect to controlling groundwater pollution.Volatile organic contaminant has higher vapour pressure, water-soluble and lower organic partition ratio, viscosity, interfacial tension, they are once enter into soil, aeration zone then can be caused to pollute, pollute waterbearing stratum under certain condition, bring serious threat to environment for human survival and human health.Priority pollutants in 68 kinds of water of China's regulation.The waterhead area organic contamination investigation of main cities, China Henan shows, chlorobenzene is had to detect in underground water, the monitoring of 2006-2007 continuous 2 years Organic Contamination of Groundwater things to Henan contaminated site finds, the maximum acceptable concentration of the tap water that the concentration of chlorobenzene has specified more than USEPA.
Discharge Engineering in Shanghai Jinshan District town level centralized water supply unit, day service discharge 2.4 ten thousand t, relates to 10 villages (region), water supply population about 2.5 ten thousand people.This centralized water supply unit intake water area water-quality yellowing on August 25th, 2012, its downstream finds that the dead float for fishing of part floats.Combine investigation through Environmental Protection Agency, public security department and Bureau of Water Resources to think and may pollute for chlorobenzene, source water water quality monitoring (WQM) on August 25 chlorobenzene content 200 μ g/L, exceedes national drinking water standard, threatens the healthy of the regional masses that supply water.
Chlorobenzene common are organic pollutants in soil and groundwater, easily enters in soil and groundwater with rainwater or irrigation water by eluviation, cause the pollution of soil and groundwater body.At present about the traditional method of chlorobenzene Pollution abatement in underground water has following several:
1. active carbon adsorption
With the chlorobenzene in charcoal absorption water source, without the need to adding any chemical reagent, technical requirements is not high, lower concentration advantages of good adsorption effect, and some materials being difficult to degrade can directly adsorb on the activated carbon.By having investigated gac dosage, adsorption time, concussion surged the factors such as plate stroke to the impact of removal effect.
This method technical maturity, simple to operate reliable for effect, but adsorption efficiency is unstable, effective when chlorobenzene is in lower concentration, during high density, process is unstable, the active adsorption life-span is short, carrier needs to carry out secondary desorb just can carry out circulating use, and by the solution after solvent desorption, forms again the mixture containing chlorobenzene, how to be isolated again, to need to study further.
2. aeration process repairing method
Pressurized air is injected underground water saturation zone by aeration process reparation, gas moves upward in process and causes volatile contaminant to enter gas phase from the soil body and underground water, make the air containing pollutent rise to unsatalation zone, then reach remove the object of pollutent by the process of gas phase extraction system.The based technique for in-situ remediation of this process underground water saturation zone volatile organic contaminant, owing to can the advantage of original position construction make it be used widely, be applied to molecular weight more, easily becomes the pollutent of gas phase from liquid phase.
But aeration process repairing method is easily subject to the factor impacts such as gas flow shape change, number of bubbles, bubble size, gas channel density, reduce processing power because treatment process is different simultaneously.Aeration process repairing method in force, if there is local low-permeability soil layer in zone of pollution, air and pollutent are difficult to fully contact, if there is structural crack or zone of fracture in underground water saturation zone, the air injected then easily forms preferential flow, cause aeration short circuit, greatly affect process range and treatment effect, zone of pollution is difficult to effectively be repaired.Simultaneously aeration process repairing method is also subject to water-soluble and volatile direct impact of soil response type, place uniformity, ground water table and flowing, pollutent, such that remediation efficiency declines, cost increase.
3. in situ chemical oxidation method
The oxygenant that in-situ chemical recovery technique adopts is as permanganate, Fenton reagent, hydrogen peroxide and persulphate, oxygenant is injected into underground pollution district, soil and waterbearing stratum itself are containing a large amount of virgin iron mineral, and under the effect of iron mineral catalysis, oxidizing reaction can the organic pollutant of effectively rehabilitating soil and underground water.Research shows that in-situ chemical recovery technique easily makes reparation district soil produce mineralising, makes reparation district soil compaction, bad hydraulic permeability, changes and repair district's Soil structure.
