Description
Technical field
The present invention relates to the oxidation removal of chlorophenols compound, specifically a kind of catalytic wet air oxidation is handled the method for chlorophenols organic pollutant.
Background technology
Since the thirties in 20th century, chlorophenols compound (CPs) is widely used as wood preservative, rust-preventive agent, sterilant and weedicide etc., and in paper pulp bleaching process, also can produce the waste water of a large amount of chlorophenols, in the Asia, Africa and South America also is used for the control of schistosomicide, and is therefore very huge in the industrial scale of many industrialized country CPs.Simultaneously, 2-chlorophenol, 2,4-two chlorophenols, 2,4,6-trichlorophenol and Pentachlorophenol all are the very high materials of toxicity, are listed in the Black List of priority pollutants by U.S. EPA.A large amount of uses of chlorophenols compound make a large amount of CPs pollutents enter environment, cause very big harm to physical environment.Therefore, this compounds of removing in the environment is a major challenge that the mankind face.
The method of handling chloride phenols wastewater at present is a lot, and method commonly used is biological degradation method, absorption method, extraction process, liquid membrane separation method.But the time that biological process needs is long especially, and inapplicable for the processing of high density chlorophenol waste water.In addition, biological degradation chlorophenols waste water also can the bigger dioxin pollution thing of toxigenicity.(L. G. Oeberg, Chemosphere, 1992) high-level oxidation technology is the technology of the organic pollutant of the processing difficult degradation that grows up the eighties in 20th century, its principal feature is to produce hydroxyl radical free radical by chemical reaction, make organic pollutant be degraded into water effectively, carbonic acid gas and mineral ion; Mainly comprise ozone oxidation, photochemical catalytic oxidation, wet oxidation, H2O2/UV, Fenton, methods such as O3/UV.Handle in the method for chlorophenol at advanced oxidation processes, the catalytic oxidation system of Meunier (Science 1996) is an oxygenant with hydrogen peroxide, iron-phthalocyanine is a catalyzer, handle the chlorophenols organic pollutant, the mineralization rate of carbon is 14% in the Trichlorophenol, and the mineralization rate of chlorine is 70%.Metal phthalocyanine catalyst has been invented in world patent application (S.Muriel, WO0059836,2000), is oxygenant with hydrogen peroxide, is used for handling Trichlorophenol waste water.In (Science 2002), be catalyzer with tetramino iron macrocylc compound in the catalyst system of Collins, hydrogen peroxide is an oxygenant, and the mineralization rate of Trichlorophenol is 35%, and the mineralization rate of chlorine is 83%.The problem that exists mainly is used oxygenant such as H at present
2O
2And O
3Cost an arm and a leg, make processing cost higher relatively, and in catalytic oxidation process, the synthetic cost of iron-phthalocyanine catalyzer etc. is also higher relatively, in addition, and some transition-metal catalyst instabilities, easy inactivation, but the existence of these problems is feasible very little for the processing industrial prospect of chlorophenols waste water.
Summary of the invention
The object of the present invention is to provide a kind of catalytic activity height, treatment effect is good, the reaction conditions gentleness, and processing cost is low, but the method for the big catalyzing oxidizing degrading chlorophenol pollutant of industrial applications prospect.
For achieving the above object, the technical solution used in the present invention is:
The waste water solution that fills the chlorophenols organic pollutant is packed in (stainless steel) reactor that has liner, in liquid-phase system, add catalyzer, charge into air in certain amount or oxygen (or ultrapure oxygen) then, oxidation removal organic pollutant under the agitation condition of in middle gentleness, pressing; Temperature of reaction is 30～300 ℃, and reaction pressure is 0.1～10Mpa, and wherein oxygen partial pressure is 0.1～5.0Mpa;
Described catalyzer is to be the soluble salt of active cation component with metal K, Na, Mg, Ca, Ba and/or Al etc.; Cationic volumetric molar concentration is 0.01～10 times of required removal organic pollutant volumetric molar concentration in the waste water in the catalyzer that is added.
Catalyzer in the reaction system is the salts solution of nontransition metal, and the soluble salt of catalyzer is with NO
3 -, NO
2 -, SO
4 2-, SO
3 2-Or CO
3 2-Deng being the active anion component.
Stirring velocity is generally 100rpm～1000rpm.
Reaction times of the present invention generally is no more than 4 hours, common reaction times 〉=5 minute, and the reaction times is preferably 0.5～4 hour; Temperature and pressure also is the important factor of influence reaction, in reaction, and 10 ℃ of the every risings of temperature, speed of reaction just increases by 2～4 times, but temperature is too high, also can increase energy expenditure, temperature of reaction is generally 30～300 ℃, is preferably 60～200 ℃, is preferably 90～150 ℃.
In reaction system, oxygen partial pressure also is the principal element of influence reaction, oxygen partial pressure increases, help the dissolving of oxygen in water, thereby help the carrying out that react, but system pressure is too high, material to reaction requires high, simultaneously, it is very little to the raising degree of reaction to increase oxygen partial pressure after oxygen partial pressure reaches certain value again, therefore must select suitable temperature and pressure; Reaction pressure is preferably 0.1～5Mpa; Oxygen partial pressure can be 0.1～5.0Mpa, is generally 0.2～3Mpa, is preferably 0.2～1.5Mpa, and the best is 0.5～1.0Mpa.
The organic pollutant structural formula of the described common oxidized removal of need is as follows:
n＝1～5。
The present invention has following advantage:
1. catalytic activity height, the reaction conditions gentleness.The present invention is in having the stainless steel cauldron of liner, is oxygenant with the air or oxygen, is catalyzer with the salts solution of nontransition metal, the chlorophenols organic pollutant is oxidized to carbonic acid gas, carbon monoxide, water and the small molecules carboxylic acid that some are nontoxic.Can reach 100% removal for chlorophenol pollutant, the mineralising efficient of carbon can reach 80%, and the mineralization rate of chlorine can reach 96%.
2. processing cost is low, but industrial prospect is big.Because used oxygenant and the catalyzer of the present invention cheaply is easy to get, treating processes is easy, and the pilot scale reaction has also obtained the good treatment effect, but therefore catalytic oxidation of the present invention has the application prospect of industrial treatment chlorophenol pollutant.
3. environmental friendliness.Reaction system of the present invention is simple, and is convenient and practical, and catalyzer cheaply is easy to get, and the reactive behavior height is thorough to the removal of pollutent.Catalyzer can not cause secondary pollution to environment in used concentration range.
4. applied widely.The present invention is applicable to the processing of chlorophenol pollutant waste liquid, and the processed organic pollutant structural formula of common need is expressed as follows:
n＝1～5。
