Abstract

The invention relates to a modified loading nano composite photocatalyst which takes titanium dioxide as main part and adopts new reaction technique to degraded the organic industrial wastewater in a water processing system (see attached drawing 1 in Instruction). The main point on preparing the catalyst lies in that titanium dioxide active compounds loaded on different carriers are employed to prepare a loading photocatalyst with grain diameter of 5-40nm; meanwhile, different elements are mixed into the loading photocatalyst to reduce the composition between photoproduciton electron and cavity, which enables the catalyst to move the light absorbing wavelength thereof towards the visible regions, thus effectively improving the degradation rate of organic pollutants as a new environmental-friendly catalyst. As to the new technique of processing the organic industrial wastewater, the invention overcomes the defects that the present photocatalysts are only used for degrading the organic industrial wastewater with low concentration. The catalyst being irradiated respectively or simultaneously under sunbeam and ultraviolet light can decrease COD values of high-concentration organic industrial wastewater from 10000-40000mg/L to less than 100mg/L in short time, thus meeting the national emission standard.

Photocatalysis oxidation treated high concentration organic trade waste
Technical field
What the present invention relates to is load type nano composite photocatalyst and the technique for applying thereof of preparation based on titanium dioxide.Wherein adopt the method for co-precipitation in conjunction with sol-gel, emphasis carries out modification by the load of titanium dioxide on different carriers with the different elements that mix, prepare the nano composite photo-catalyst that particle diameter is 5~40nm, not only improve photocatalytic activity, also reduced the compound degree in light induced electron and hole.This catalyst can adopt ultraviolet light and visible light radiation condition respectively or simultaneously in water treatment facilities (seeing Figure of description 1), effectively degradable organic pollutant is an environmentally friendly catalyst of new generation.This photochemical catalyst has overcome present photocatalysis technology can only be used to the to degrade shortcoming of 10~3000mg/L low concentration organic industrial sewage, as patent " preparation of catalyzing oxidizing degrading organism under sun lighting load type nano composite photocatalyst ", application number: 2005100830380; Patent " a kind of method of photocatalysis degradation organic contaminant and special-purpose solid-phase photocatalyst thereof ", application number: 200510064496.X.Catalyst of the present invention not only can be used for the low concentration organic industrial sewage of degrading, the COD value that also can be used for degrading is the high-concentration organic industrial waste water of 10000~40000mg/L, and by the reaction new technology, not only finished recycling, and COD value of waste water can have been dropped to below the national industrial wastewater discharge standard 100mg/L catalyst.
Technical background
Along with industrial expansion, the quantity of industrial wastewater is increasing, and composition is also increasingly sophisticated, and the last outlet of industrial wastewater has two usually, be the irrigated farmland or enter water body, if can not good treatment, certainly will will cause severe contamination harm environment water body to a large amount of industrial wastewaters.So must before discharging, should suitably be handled, make it reach the sewage drainage standard of country's promulgation.
The modern industry wastewater treatment method mainly is divided into physical treatment process, method of chemical treatment and biological treatment three classes.
Physical treatment process is meant the method that comprises oil film and oil droplet by undissolved suspended state pollutant in physical action separation, the recovery waste water, can be divided into gravitational separation process, centrifugal separation and sieving and hold back method etc.
Method of chemical treatment is meant by chemical reaction and separates with effect of mass transmitting, removes the method that is dissolving, colloidal state pollutant in the waste water or is translated into innocuous substance.In chemical treatment, coagulation, neutralization, redox etc. are arranged based on the unit that adds medicament generation chemical reaction; And extraction, stripping, stripping, absorption, ion-exchange and electrodialysis and counter-infiltration etc. are arranged based on the processing unit of effect of mass transmitting.The existing chemical action of processing of utilization effect of mass transmitting have again in relevant physical action, so also can from fractionation, branch away, become another kind of facture, be physicochemical treatment method.
Biological treatment makes the organic pollution that is dissolving, colloid and fine suspended state in the waste water be converted into the method for stable, harmless material by the metabolism of microorganism.According to the difference of microorganism, biological treatment can be divided into aerobe again to be handled and anaerobic bio-treated.Biological wastewater treatment is widely used to be the aerobe facture.By tradition, the aerobe facture is divided into activated sludge process and biomembrance process again.The anaerobic bio-treated method has another name called the biological reducing facture, is mainly used in organic wastewater and the mud of handling high concentration.
Pollution in the waste water is diversified, often is difficult to all pollutants are eliminated with a kind of processing unit, needs usually just can reach requirement by after the treatment system processing of being made up of several method and several processing unit.
In decades recently, a kind of new method of degradable organic pollutant-conductor photocatalysis oxidizing process, be subjected to the attention of researcher, various countries have dropped into great amount of manpower and material resources and have launched the basic theory of semiconductor photocatalysis technology and the research of application foundation.
The key issue of support type conductor photocatalysis technology is: under the condition of illumination, semiconductor energy produces light induced electron and hole, and optical excitation electronics and photoproduction high energy holes can be 10 9Compound and lose activity in second.Therefore how to catch the optical excitation electronics fast, it is very important making itself and high energy holes effectively separate to reduce compound efficient to raising conductor photocatalysis degradable organic pollutant.In order effectively to utilize solar energy to improve photocatalytic activity, this research institute has prepared support type high-dispersion nano composite photo-catalyst by doped tin, iron, zinc, cerium, molybdenum, silver, platinum, manganese, tungsten, silicon, vanadium, zirconium, aluminium, copper, cadmium element simultaneously.By doped chemical, active component has reduced the compound of light induced electron and hole, and the optical excitation scope is moved to visible light by ultraviolet light, has made full use of the solar energy of green non-pollution.Reach the catalytic active component high dispersive by carrier, particle diameter has also improved photocatalytic activity simultaneously at 5~40nm.The application started a kind of brand-new stable, firmly, loaded nano composite titanium dioxide photochemical catalyst and use new technology efficiently, developing can be respectively or have highly active multifunctional photocatalysis agent simultaneously under ultraviolet light and solar light irradiation condition, has also set up the new technology of catalyzing oxidizing degrading organic industrial sewage simultaneously.
Summary of the invention
The present invention adopts co-precipitation to make TiO in conjunction with the method for collosol and gel 2Load on the carrier with doped chemical, to prepare a kind of new catalyst, to its objective is that particle diameter is little, decentralization is high, specific area is big in order obtaining, Heat stability is good, catalytic activity are high can respectively or have efficient light activated load type nano composite photocatalyst simultaneously under ultraviolet light and visible light condition.This catalyst can be that the organic industrial sewage COD value of 10000mg/L~40000mg/L is reduced to below the discharging standards 100mg/L with concentration under the water treatment technology condition of design voluntarily.
