Abstract
The irradiation method of degrading hexachlorobenzene in water is one high efficiency energy saving water treating technology. High energy electron beam or gamma ray radiated during the decay of radioactive atom is utilized to treat water containing hexachlorobenzene for degrading hexachlorobenzene.
Description
Technical field
The present invention relates to the method for Perchlorobenzene in a kind of water body of degrading, the method for specifically utilizing irradiation that the Perchlorobenzene in the water body is degraded.
Background technology
Calendar year 2001, by United Nations Environment Programme (UNEP) (UNEP) tissue, in the council of ministers of Sweden, signed the international law constraint treaty of 12 kinds of typical persistence organic compound of a control (POPs), China is one of signatory country.
United Nations Environment Programme (UNEP) (UNEP) carried out Global Environment Facility's project evaluation of relevant PTS in 2000, the expert is consistent to be thought to speak with simple word and defines the persistence Toxic, though these materials are enjoyed following general character really: organic (comprising that metal is organic) material; Slowly degraded in environment; Biology gathers; Has toxicity.
Perchlorobenzene is one of 12 kinds of listed POPs of above-mentioned pact, also is a kind of typical PTS.It is carcinogenic substance that Perchlorobenzene is confirmed to be, and human health and environment are all had serious harm, no matter still is listed on " Black List " of priority pollutants in the equal name of European Union in the U.S..Perchlorobenzene once generally was used for all types of industries production and pesticide producing, intermediate as organic synthesis, the sterilant and the wood preservative of seed are used for organic synthesis, can also be used to produce Pentachlorophenol, fluorocarbon and paper dipping,, the use of agricultural chemicals simultaneously makes Perchlorobenzene form pollution of area source.The approach that Perchlorobenzene enters environment comprises waste water, air and the stack gas of Incineration of waste generation and the release of flying dust that contains these products, thereby Perchlorobenzene is distributed widely in the environment.
The chemical property of Perchlorobenzene is stable, is difficult to biological degradation, and is lasting in environment.To mainly be present in the vapor phase after being discharged into atmosphere, degraded is slow (being estimated as 2 years with the transformation period of hydroxyl free radical reaction) extremely, and the whole world migration of long distance can take place.Wet deposition and the dry deposition Perchlorobenzene in can the physical removal atmosphere.After entering water body, Perchlorobenzene will obviously be assigned in bed mud and the suspended substance.It volatilizees very fast from water, and still the strong adsorption with bed mud causes its persistence very strong. and Perchlorobenzene biomagnification in the fish body enters food chain (the food market investigation is found can detect in the food).The mankind can be exposed to Perchlorobenzene by ambient air, contaminated tap water and food, polluted soil and occupational environment.
The standard value of Perchlorobenzene is for being no more than 0.01 μ g/L in The World Health Organization's suggestion tap water.China's Perchlorobenzene at present also has production, also is being used as chemical intermediate.
Owing at present time decades has been carried out in the research of 12 kinds of typical POPs both at home and abroad, we can be generalized to a lot of achievements in research in the research and improvement of other persistence Toxics modestly, but simultaneously, concrete material also needs concrete analysis.Chlorobenzene compound is compared with arene compounds, biodegradability reduces greatly, along with increasing of chlorine substituent, the activity of chlorobenzene compound reduces one by one, Perchlorobenzene is minimum, major cause is that high electronegative chlorine atom makes phenyl ring become a very difficult oxidized electrophobic ring, so Perchlorobenzene almost can not be biochemical.Have the scholar to find that the microorganism in the specific mud had certain removal effect to Perchlorobenzene, but it is subjected to environmental influence bigger.Perchlorobenzene is very insensitive to illumination, and what Degradation illumination does not almost have to Perchlorobenzene.Polystream, particularly Perchlorobenzene have very high thermostability, are difficult to destroyed.Moreover, when containing the urban solid garbage of Perchlorobenzene, burning disposal also can produce another kind of high toxicity pollution substance-Dioxins.This shows that the Perchlorobenzene chemical property is highly stable, handle very difficulty.Carry out big quantity research both at home and abroad for the degraded and the removal of Perchlorobenzene at present, but also do not had special ideal method.
In sum, for the Perchlorobenzene of one of generally acknowledged 12 kinds of POPs that seriously jeopardize human health and environment in the whole world and typical PTS, it is very urgent to research and develop a kind of comparatively ideal effective treating method.
Summary of the invention
The objective of the invention is the problem that exists at above-mentioned prior art, the method for the Perchlorobenzene in a kind of method degraded water body that utilizes irradiation is provided, is a kind of water technology of high-efficiency and energy-saving type.
Technical scheme of the present invention:
A kind of method of utilizing Perchlorobenzene in the irradiation-induced degradation water body, its gamma-rays that radiates when adopting high-power electron beam or radioactive atom decay is handled the water body that contains Perchlorobenzene, and the Perchlorobenzene in the water body is degraded.
Wherein irradiation source is a radionuclide
60Co or
137Cs, irradiation dose is high more simultaneously, and degradation rate is high more;
Wherein high-power electron beam is produced by high-energy electron accelerator;
Wherein water body is the tap water water body;
Higher pH value has promoter action to the irradiation effect.Under the identical situation of other condition, pH value is high more, and degradation rate is high more, and treatment effect is good more.
Wherein in the water body at CO
3 2-Concentration is higher to have promoter action to the irradiation effect.Under the identical situation of other condition, carbonate concentration is high more, and degradation rate is high more, and treatment effect is good more.
Along with more concerns are dropped into to persistence organic pollutant (POPs) and the staying quality poison material (PTS) that enters the difficult degradation in the environment in countries in the world, the new technology of developing a kind of toxic organic compound of degrading just becomes more and more urgent, is exactly to produce under these circumstances radiation application in the processing of this type of material.
The gamma-rays that radiates during the radioactive atom decay has great penetrating force, and industrial modal irradiation source is a radionuclide
60Co and
137Cs is used for the processing of water and mud.And the controllability of high-power electron beam is good, and speed of reaction is fast, and penetration power is strong, has realized industrial applications at home and abroad.There are some researches show that high-power electron beam and gamma-radiation there is no remarkable difference to the effect of compound in the water body.High-power electron beam and gamma-rays can both produce the similar activity intermediate, and major different is that the gamma-ray dosage release rate in cobalt source is relatively low.The research that utilizes radiotechnology that waste water is handled has been carried out the long period abroad, studies show that gamma-rays and electron beam to containing the waste water of heavy metal, and phenolic wastewater, cyanide wastewater, industry contain anthracene, the quinone waste water from dyestuff all has the good treatment effect.Relevant report is few both at home and abroad at present to be applied to the processing of tap water for gamma-rays and electron beam irradiation.
