Description

A kind of light is urged the method that halogenated organic matters in the water is removed in dehalogenation compound/light coupling
Technical field
The present invention relates to a kind of method of removing halogenated organic matters in the water.
Background technology
Halogenated organic matters is meant that 1 of linking to each other with C in the structure in the organism or a plurality of H by the organism that halogen replaces, comprise fluoro, chloro, bromo and iodo organism etc.Common halogenated organic matters has: trifluoroacetic acid, perfluoro octyl sulfonic acid, methylene dichloride, trichloromethane, tetracol phenixin, ethylene dichloride, tetrachloroethane, chloroethanol, Monochloro Acetic Acid, dichloro acetic acid, trichoroacetic acid(TCA), chlorobenzene, Polybrominated biphenyl, Poly Brominated Diphenyl Ethers, paraxin, diclofenac, clofibric acid, chlorophenol, Chlorodracylic acid, parachloronitrobenzene, methyl bromide, bromic ether, bromohydrin, tribromoacetic acid, one chlorine dibromoacetic acid, bromobenzene, bromine phenol, Polybrominated biphenyl, Poly Brominated Diphenyl Ethers, iodine alkane, iodohydrin, Schering AG) etc.
It is toxic and natural, ecological is had a pollutent of significant damage to organism that halogenated organic matters is generally considered to be, wherein some halogenated organic matters is confirmed to be teratogenesis, carcinogenic, mutagenic three and causes material, and some is endocrine disrupter (EDCs) and environmental persistence organism (POPs).
Most in the world rivers and lake water have been subjected to the pollution in various degree of halogenated organic matters; Also in various degree the existence that detects halogenated organic matters, particularly offshore area of each big midocean, the part sea pollution is serious; The part underground water of China, the U.S., Canada, Japan and a lot of European countries also has been subjected to the pollution of halogenated organic matters.Because the groundwater environment condition is more special, halogenated organic matters enters body of groundwater and just is difficult to remove.Typical pollutent is as trieline, zellon, Perchlorobenzene, polychlorobiphenyl, halogen acetic acid etc. in the underground water.Show according to environmental surveys widely both at home and abroad, in the wildlife body of occurring in nature in various degree the accumulation that has detected halogenated organic matters also residual, as Perchlorobenzene; Because most of halogenated organic matters has certain volatility, human also being exposed in the environment of halogenated organic matters is as tap water, food, air etc.In indivedual areas, also detected corresponding organism in the human body, as chlorobenzene.
Therefore be necessary very much halogenated organic matters is removed.And conventional treatment process is not fully up to expectations to the removal effect of halogenated organic matters.Through various countries scientist effort for many years, developed the methods of taking out halogenated organic matters in a lot of gradually, removed method, advanced oxidation processes, transition metal-catalyzed reduction method, vacuum ultraviolet (VUV) and high-energy radiation is sent out and reactive infiltration wall technology etc. as gas formulation, active carbon adsorption, electrochemistry.Though the whole bag of tricks can both carry out to a certain degree removal to halogenated organic matters, the whole bag of tricks all has certain drawback, and some method cost is too high and can't large-scale application.
The gas formulation, be wallop when aqueous solution vapour pressure surpasses external pressure when utilizing water vapour by water layer and liquid constantly in bubble the effect of evaporation diffusion make the water treatment procedure that volatile dissolved matter matter is constantly separated in the water from water, be a kind of diffusion process of physics.Its shortcoming is: can only remove some volatile organic matters, deliquescent halogenated organic matters such as trichoroacetic acid(TCA) are not then had removal effect; Secondly, it is lower that this method is removed efficiency ratio for the halogenated organic matters of high density, in order to reach good clearance, needs multistage gas processing, the cost height; In addition, the secondary pollution gas of this method generation also needs further processing.
Active carbon adsorption, be to utilize the duct of gac distribution and huge specific surface area to come absorb polluted matter, it can well remove in the water hydrophobic organic compound of the overwhelming majority, as chlorobenzene etc., but does not remove substantially for the hydrophilic organics hydrophilicity people halogen acetic acid in the water, halohydrin etc.; Next is for the organic matter removal poor effect of the high density in the water; Similar with the gas formulation, active carbon adsorption also produces secondary pollution, need further handle gac; Gac needs regular regeneration to change, and costs an arm and a leg; Water quality water conservancy condition is bigger to its adsorption effect influence, and capacity of resisting impact load is not good, and operation cost is higher.
Electrochemistry is removed method, is to utilize polarization of electrode to produce living radical, the method for the pollutent in direct or indirect oxidation/reductive water.At present this method mainly obtains certain effect in the laboratory, but the obstacle of this method maximum be also do not have at present a kind of can negative electrode and anode can both stable existence electrode materials, and this kind material require has good antifouling property.Noble metal electrode, as the platinum material, at present usefulness is many, but these precious metal materials can catalytic electrolysis water, and therefore waste electric energy greatly also is easy in addition be polluted by some chemical substances or intermediate product, and has influence on degradation efficiency.The diamond of surface plating boron is used to do electrode at present, and has under lab also obtained certain effect, and still this material is had relatively high expectations to the effect functional group of diamond surface, and costs an arm and a leg.Large-scale practical application does not have actual operation parameter, lacks the relevant information of stable aspect.
Advanced oxidation processes is to utilize the very strong material of some oxidisability such as ozone, hydrogen peroxide etc., produces the hydroxyl radical free radical HO of strong oxidizing property, the deoxidation pollutent.This method is fine to some conventional readily oxidizable substances such as removal effects such as phenol, oil of mirbane, even can reach mineralising.But organism is after halogen replaces, because the electrophilic inductive effect of halogen, cloud density reduces in the molecular structure, and is therefore more difficult by the HO attack, and speed of reaction reduces.Some halogenated organic matters is as tribromoacetic acid, trichoroacetic acid(TCA), with second order rate constant<10 of HO 6M -1s -1, therefore, be difficult to they be removed fully with the mode of advanced oxidation.Though the introducing of catalyzer can accelerated reaction, efficient is still not high, moreover adds catalyzer and increase cost, can affect to water quality yet.Recently, ultrasonic technique research many, because the effect of ultransonic cavatition and acceleration mass transfer, the ultrasonic associating with advanced oxidation uses with removing the pollutent effect than independent advanced oxidation efficient height, also useful ultrasonic and advanced oxidation coupling removal perfluorocarboxylic acid and perfluoro octyl sulfonic acid, but efficient is still lower, and relatively power consumption, has increased use cost.
Transition metal-catalyzed reduction method is meant and utilizes the special catalytic performance catalysis H of transition metal (as Pd etc.) 2Replace the halogen on the halogenated organic matters,, and then reach the purpose of reductive dehalogenation as chlorine.This method can be studied the chlorine that is used for removing trieline, zellon etc. in the laboratory, and when the transition-metal catalyst of capacity was arranged in the system, removal effect can reach level preferably.But this method has also just obtained certain effect at present in the laboratory, does not also come into operation, and actual operational circumstances and running cost are still waiting further investigation; But from breadboard running condition, transition-metal catalyst is subjected to the pollution of organism easily in this method, needs frequent regeneration backwash; In addition, sulfocompound in the system, as vitriol etc., can produce sulfide under this reduction system and action of microorganisms, this sulfide can make poisoning of catalyst, and then reduces its catalytic activity, therefore catalyzer needs frequent regenerating with hypochlorite solutions, keeping corresponding catalytic activity, therefore operate cumbersome, poor stability.
The vacuum ultraviolet (VUV) method is the ultraviolet ray excited water molecules that utilizes high-octane short wavelength, produces multiple free radical, comprises HO, e Aq -, H etc., oxidation/go back parent pollutant.If the vacuum ultraviolet (VUV) method produces short wavelength ultraviolets such as 172nm with electrodeless ultraviolet lamp, the cost of lamp can be very high; And the part of low pressure mercury lamp generation short wavelength ultraviolet seldom, general<6%, therefore relatively power consumption; In addition, the penetrativity of short wavelength ultraviolet in water is very weak, and be general<1cm, therefore greatly reduces service efficiency, limited it and be extensive use of; If add catalyzer, then the catalytic capability of catalyzer, recovery and regeneration etc. all are a series of problems that must solve.High-energy radiation and vacuum ultraviolet (VUV) method principle are approaching, but cost all than higher, it needs source of radiation, costs an arm and a leg; And radsafe has limited its use in tap water; Remove the existing application of sewage with it, but cost is too high, management is inconvenient.
Reactive infiltration wall technology is the technology that the polluted-water that utilizes the permeability wall to pass through carries out scrubbing, is a kind of original place treatment technology, is mainly used in phreatic reparation.This method is used to phreatic reparation at present, utilizes Zero-valent Iron to remove halogenated organic matters in the underground water as this technology.This method can effectively be removed organism such as vinylchlorid, but only produces effect in the shallow-layer waterbearing stratum, has therefore limited its use.
Therefore, be necessary very much to research and develop a kind of can be effectively, economical, convenient and can broad spectrum ground removal water in the water technology of halogenated organic matters, this technology not only can be used in the household drinking water, also can be used in city water factory and the sewage work, can also be used in face of land rivers water, lake water and the phreatic reparation of overall situation, even can be used in brine disposal and the reparation.
Summary of the invention
The present invention seeks to adopt gas formulation, active carbon adsorption, electrochemistry to remove the various drawbacks that halogenated organic matters exists in method, advanced oxidation processes, transition metal-catalyzed reduction method, vacuum ultraviolet (VUV) or the reactive infiltration wall technology removal water, and the method for halogenated organic matters in the water is removed in the short dehalogenation compound of a kind of light that provides/light coupling in order to solve.
