Description
Technical field
The invention belongs to underground water pollution processing means field, be specifically related to a kind of vortex type air propelling method and decompose device and the method for work thereof of carbon tetrachloride in subsoil water.
Background technology
Carbon tetrachloride (CCl4) it is low boiling organic chlorohydrocarbon (proportion 1.591g/cm of a kind of synthetic3, boiling point 77 DEG C), it is slightly soluble in water.Foreign study shows: carbon tetrachloride belongs to typical hepatotoxic agent, during high concentration, is first to affect central nervous system, affects liver, kidney subsequently.It has persistency, extended residual and bioconcentration in the environment, has therefore been listed in by U.S. EPA from 1979 " containing the pollutant of priority acccess control in carbon tetrachloride laboratory ", has also been listed in 68 kinds of " pollutant of priority acccess control in water " lists by China.
Eighties of last century the seventies manufactures due to a large amount of and use pesticide, causing in some area laboratorys by Carbon Tetrachloride Contamination, the water-bearing layer near the Michigan water-bearing layer and Canada Ottawa of the U.S. is all by crossing carbon tetrachloride and polluted (it in water-bearing layer many exist with nonaqueous phase (NAPL)).
The pollution that before the U.S., FortordArmy causes in military base makes CCl in the municipal water supply of Marina4Exceeding standard, in August, 2000 records CCl4Concentration reaches 15 μ g/L.In the laboratory discharge residual liquid in U.S. Livermore area, monitoring finds that the stacking of poisonous Harmful Waste causes CCl4The generation of pollutant, CCl in noxious substance percolate4At concentrations up to 500 μ g/L.In April, 2000, CCl in laboratory in the MW-10 well near Hafner&Sons refuse landfill4Concentration reaches 6.3 μ g/L.
The deficiency of existing Treatment process
Carbon tetrachloride is to common are organic pollutants, easily enters soil and water body with rainwater or irrigation water by eluviation, causes the pollution of soil and water body.Have following several about the traditional method of carbon tetrachloride residual liquid pollution control in laboratory at present.
1. active carbon adsorption
With the carbon tetrachloride residual liquid in activated carbon adsorption water source, it is not necessary to adding any chemical reagent, technology is less demanding, low concentration advantages of good adsorption effect, some materials being difficult to degrade can directly adsorb on activated carbon.By having investigated the factor impacts on removal effect such as activated carbon dosage, adsorption time, temperature.
This method technical maturity, simple to operate reliable for effect, but adsorption efficiency is unstable, carbon tetrachloride residual liquid is in during low concentration effective, processes instability during high concentration, the active adsorption life-span is short, carrier needs to carry out secondary desorbing just can be circulated utilization, and by the solution after solvent desorption, forms again the mixture containing carbon tetrachloride, it is isolated the most again, needs research further.
2. in situ chemical oxidation method
Oxidant permanganate, Fenton reagent, hydrogen peroxide and the persulfate etc. that in-situ chemical recovery technique uses.Injecting oxidant containing substantial amounts of native iron mineral, under the effect of iron mineral catalysis, oxidation reaction can effective renovation of organic pollution thing.Research shows that in-situ chemical recovery technique easily makes reparation district produce mineralising, soil compaction, bad hydraulic permeability, changes reparation plot structure.
3. biological restoration
Utilizing bio-inert and organic clay adsorbed bioactive bacterium, by biological metabolism, reduce the engineering techniques of poisonous and harmful compound in underground environment, biology in situ repairing method can process large-scale pollutant, and can complete decomposing pollutant.
Biology in situ method is an emerging technology for Organic Pollution source in treatment of laboratory at present, the key factor of biological restoration is suitable electron acceptor, and the oxygen receptor that has been best electricity, due to this electron acceptor of deficiency of oxigen in the environment, the supply of microbial nutrition material is not enough simultaneously, and the biodegradation also making microorganism can not be lasting.
4. permeable reactive wall repairing method
Utilizing the dependent response district being filled with Active reaction medium material, when passing through in contaminated laboratory, polluter therein acts on reaction medium generation physics, chemical and biological etc. and is degraded, adsorbs, precipitates or removes, so that sewage is purified.
But permeable coefficient tensor exists the most blocked, the its native environmental conditions such as the oxidation-reduction potential in laboratory easily go to pot, the shortcomings such as operation maintenance is relative complex, add that bimetallic systems, nanotechnology are relatively costly, and these factors hinder developing further and wideling popularize of permeable coefficient tensor.
