Description
Technical field
The invention belongs to a kind of absorption-catalyst and application process thereof, relating in particular to a kind of is the multicomponent absorption-Preparation of catalysts and the using method of main active component with the transition metal.
Background technology
The source of wastewater containing phenol is very extensive.Coke-oven plant, oil plant, petrochemical industry, gas generating station, plastic molding and processing plant, resin processing plant, insulating material factory, wood preserving plant, pharmaceutical factory and Fibre Plant etc. all produce wastewater containing phenol.The importance of phenol in water pollutes owing to it to the high toxicity of aquatic life be difficult to biodegradation.Phenol content in all strict restriction environment in countries in the world.The maximum permissible concentration of volatile phenol is distributed as in China's regulation water body: drinking water 0.002mg/l, agricultural water 1.0mg/l, industrial wastewater discharge standard 0.5mg/l.This shows that the wastewater containing phenol source is wide, harm is big, standard is tight.How handling effectively and utilizing wastewater containing phenol is problem that has universal significance in the environmental pollution field.
At present, the adsorption technology based on the good absorption property of active carbon has a wide range of applications at organic wastewater and exhaust-gas treatment field.The adsorption capacity of active carbon is big, and high and low concentration waste water is all had removal effect preferably.But after in a single day the adsorption capacity of active carbon reaches capacity, just need handle so that utilize again it.Regeneration techniques commonly used is heat regeneration in the industry at present.In the hot regenerative process, the active carbon that adsorbs after saturated will be handled under 800-850 ℃ high temperature, and energy consumption is big; Simultaneously, high-temperature operation makes that the adsorption capacity loss late of active carbon is big, a charcoal absorption capacitance loss of every regeneration 5-15%; In addition, high-temperature operation also makes active carbon can not carry out in-situ regeneration, needs specific regenerating unit, thereby increases disposal cost and cause a certain amount of active carbon loss in transportation; At last, the pollutant of desorption also needs post processing, complex process in the heating process.
Summary of the invention
The object of the present invention is to provide a kind of active height, what the simple processing of technology contained phenol organic wastewater is absorption-catalyst and preparation method's and methods for using them of carrier with the active carbon.
It is active component that absorption-catalyst provided by the invention contains with transition metal Cu, with a kind of among K, Zn and the Ce is helper component, it is characterized in that it is carrier with the active carbon, the percentage by weight of its component is: Cu1%-10%, helper component 1%-5%, active carbon 85%-98%, and the surface area of active carbon is 500-1500m
2/ g.
Dry method catalyst for catalytic oxidation preparation method provided by the invention adopts the equal-volume co-impregnation, the nitrate mixed solution equal-volume of copper nitrate and K, Zn or Ce is total to the Immesion active carbon carrier, placed 2-6 hour in room temperature, then at 50-100 ℃ of dry 6-24 hour, calcined 2-6 hour under 200-500 ℃ of inert atmosphere at last, obtaining with the active carbon is the absorption-catalyst of carrier.
Dry method catalytic oxidation absorption-catalyst using method provided by the invention is in containing phenol organic wastewater by being the absorption-catalyst of carrier with the active carbon, and is dry at normal temperatures after absorption finishes, and feeds oxidizing gas, and air speed is 500-2000h
-1, be 200-350 ℃ in reaction temperature, reaction 1-3h, cycle applications afterwards.
The present invention has compared following advantage with prior art:
1. absorption-catalyst has the good adsorption performance.Can effectively adsorb poisonous and harmful compositions such as phenol in wastewater.
2. the catalytic oxidation mild condition is carried out under the low-temperature atmosphere-pressure, need not a large amount of water body heating pressurizations, energy consumption is low, occupation area of equipment is little, and is simple to operate, but in-situ catalytic oxidation, do not produce secondary pollution, it is not high to be particularly suitable for concentration of treatment, but toxicity is big, is unsuitable for the waste water of biochemical treatment, and the waste water of handling can reuse, has saved a large amount of water for industrial uses.
3. the adsorbed phenol initial temperature low activity height of absorbent charcoal based absorption-catalyst oxidation that supports of transition metal, the height that adsorption capacity is recovered behind the catalytic oxidation can use continuously, easily generates in batch on a large scale and uses, and cost is low.
