Description
Technical field
The utility model belongs to water treatment field, is specifically related to a kind of Carbon Tetrachloride Contamination water source treatment device.
Background technology
Tetracol phenixin (CCl
4, Carbon Tetrachloride) and be the colourless transparent liquid having special odor, highly volatile.Proportion 1.595, fusing point-22.6 DEG C, boiling point 76.8 DEG C, (density of water is 1.0 × 10 to the density 1.60 of relative water
3kg/m
3), (density of air is 1.205kg/m to the density 5.3 of relative atmospheric
3, 20 DEG C), saturated vapor pressure 13.33kPa (23 DEG C), combustion heat 364.9kJ/mol, critical temperature 283.2 DEG C, emergent pressure 45.58MPa.Tetracol phenixin is slightly soluble in water, is soluble in most organic solvent.During 25 DEG C, tetracol phenixin, solubleness is 0.08%, is conventional fire-fighting medium, is also the fine solvent of paint, resin, rubber etc.In laboratory and industrial all used as solvent and extraction agent.Tetracol phenixin quite stable, is difficult to decompose.In underground water, because diffusion is few, almost there is no biological decomposition again, therefore once body of groundwater is subject to this Substances Pollution, be difficult to self-cleaning.This material is classified as among 129 kinds " in water priority pollutants Black Lists " by the U.S., is also listed in 68 kinds " in water priority pollutants Black Lists " by China.
Source containing tetracol phenixin waste water mainly manufactures the wastewater effluent of Refrigerant 12 and trichlorofluoromethane refrigeration agent, sterilant, fire-fighting medium, dry cleaning composition; Also be the primary discharge composition producing the organic waste waters such as organic solvent, fiber degreasing agent, spices leaching agent simultaneously; Minority is used for the clean-out system etc. of chemical intermediate, fumigant, mechanical part and electronic component, and it is manufactured and wastewater effluent in use procedure.
Tetracol phenixin in industrial production discharge is the main source of environmental pollution.International cancer research institution (IARC) 1979 annual report, the annual production of the tetracol phenixin world is 80.6 ten thousand tons.Find in the generaI investigation of northern Suzhou city underground water source, seven li, southern suburbs ditch waterhead area receives Carbon Tetrachloride Contamination, and source of pollution are certain insecticide factory, and contaminated area reaches 17.5km
2, in water, tetracol phenixin maximum concentration reaches 3909.2 μ g/L, exceedes national drinking water standard 1954.6 times, and the healthy of area more than 20 ten thousand people that supply water in serious threat.In the research of somewhere, North China, detected Carbon Tetrachloride Contamination thing in river, this area, lake water, it detects Carbon Tetrachloride Concentration up to 4 μ g/L in current water.What is more, and the sewage containing tetracol phenixin directly discharges by this upstream, river course enterprise, and in discharge outlet, the concentration of tetracol phenixin is up to 80000 μ g/L.In this area's deep well, also detect a large amount of tetracol phenixin, tetracol phenixin is typical hepatotoxic agent, and its exposure concentration and frequency can affect the toxicity of its site of action simultaneously.During high density, be first affect central nervous system, affect liver, kidney subsequently; Lower concentration Long Term Contact then main manifestations to the infringement of liver, kidney.Ethanol can promote the absorption of tetracol phenixin, increases the weight of toxicity symptom.In addition, tetracol phenixin can increase cardiac muscle to adrenergic susceptibility, causes severe arrhythmia.The private medical service of people to tetracol phenixin differs greatly, and have and report that oral 3-5mL can be poisoning, 29.5mL can be lethal.At 160-200mg/m
3can occur poisoning under concentration.According to international cancer research institution (IARC) 1979 annual report, tetracol phenixin long term can cause rodentine liver cancer, is listed in class chemicals of " having carcinogenic possibility to the mankind ".
In " drinking water sanitary standard " (GB5749-2006), the limitation of regulation tetracol phenixin is 2 μ g/L.When the mass concentration of tetracol phenixin in underground water is more than 10 μ g/L, be considered to, caused by discharge, when mass concentration is at 0.01-0.10 μ g/L, be considered to caused by contaminated soil leaching by precipitation.
Tetracol phenixin 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.By the end of at present, the traditional method of administering about Carbon Tetrachloride Contamination in underground water has following several:
Method one: active carbon adsorption, with the tetracol phenixin 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.Dongguan University of Technology's chemistry utilizes powder electroless plating principle with Environmental Engineering School Peng Min, carried out experimental study to Dong Jiang, the Guangdong water factory waterhead area underground water containing tetracol phenixin, the factors such as gac dosage, adsorption time, temperature of having investigated are on the impact of removal effect.Result shows, add 80 mg/L powder electroless plating 120 min, can by 0.02 mg/L tetracol phenixin process to " drinking water sanitary standard " (GB 5749-2006) limit value (0.002 mg/L) below (specifically see tetracol phenixin experimental study _ Peng Min in powder electroless plating water _ Dongguan University of Technology chemistry and Environmental Engineering School).
This method technical maturity, simple to operate reliable for effect, but adsorption efficiency is unstable, effective when tetracol phenixin 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 tetracol phenixin, how to be isolated again, to need to study further.
Method two: aeration process repairing method.Underground water aeration method is the based technique for in-situ remediation of one process underground water saturation zone volatile organic contaminant (VOCs) grown up late 1980s, owing to can the advantage of original position construction make it be used widely, be applied to molecular weight more, easily become the pollutent of gas phase from liquid phase.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.
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, reduces 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 (specifically see saturation zone underground water aeration recovery technique progress Liu Zhibin).
Aeration process repairing method is 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.
Method three: photocatalytic oxidation, be greater than the ultraviolet excitation of energy gap at energy under, be excited forbidden band of jumping over of the electronics on n-type semiconductor atom filled band enters conduction band, produces corresponding hole on filled band simultaneously.If semi-conductor is now in solution, under the effect of electric field, side electronics is separated with hole and moves to the different positions of particle surface.Photohole has very strong electronic capability, and can capture the electronics in the organism on semiconductor grain surface or solvent, make originally not absorb the material of incident light by active oxidation, electron acceptor then can be reduced by the electronics accepted on surface.Lose the mainly water molecules of electronics at the semiconductor surface, water molecules generates OH, the photohole meanwhile produced, O after change
2deng being CO by organism permineralization together
2and H
2o.
Experiment proves, TiO in n-type semiconductor
2there is good catalytic activity.For exciting TiO
2photon energy, be greater than its energy gap (3.2eV), wavelength is 300-400nm, as high voltage mercury lamp, black lamp, ultraviolet germicidal lamp etc., can complete the transition of electronics.It is difficult by O to comprise tap water
3the chloroform of oxidation, tetracol phenixin, Perchlorobenzene, phenyl-hexachloride all have effective degradation capability (specifically administering the progress of water pollutions see Photocatalytic Oxidation for Treating Organic Pollutants in Water and photochemical method) at interior multiple pollutant.
The photolysis of pollutent have studied the more than ten years, although simply efficient and rising, use cost is too high, and practical application is little, goes back the full scale plant that neither one is very complete.
