Description
Technical field
The present invention relates to a kind of pollution photocatalytic degradation agent of water body roxarsone and a kind of water body roxarsone to pollute light
Catalytic degradation method, belongs to water-treatment technology field.
Background technique
With the development of industrial and agricultural production, environmental pollution especially organic pollution problem is caused to be on the rise.Luo Kesha
Arsine has antibacterial, anti parasitic, stimulation growth of animal, stimulation blood forming organ as a kind of feed addictive, promote red blood cell and
The generation of hemochrome improves skin-nourishing, keeps animal hair color shinny, improves carcass quality, improves food conversion ratio, and reduces cultivation
The effects of cost.Since the Ministry of Agriculture ratifies its use in 1996, roxarsone is widely used in livestock culture industry.According to agricultural
Medicated feed additive operating specification as defined in portion, 1 market pig all one's life Organic- arsenic usage amount are about 10 grams, annual quotient in 2016
Product pig delivers about 700,000,000 for sale, it means that is only discharged into organo-arsenic in this industry of pork pig 1 year into environment and is up to 7000 tons, in fact
Border number is in fact higher.Investigation statistics did to national large―scale hoggery wastewater treatment in relevant department, wherein 51% is directly discharged into fish
The pool, 16% is discharged into irrigation canals and ditches, river, and 31% is discharged into vegetable garden, field, and only 2.3% is handled by three-level septic tank.And roxarsone
It is almost non-degradable in animal body, it is expelled directly out in vitro, is directly entered in environment with feces of livestock and poultry, breeding wastewater etc..Lip river
The long-term accumulation in the soil of gram husky arsine, will affect soil ammonification and nitrification, reduces soil fertility.In soil and water
In system by biology or abiotic (mainly mineralization) reaction be changed into it transfer ability is stronger, toxicity is bigger
The inorganic arsenic chemicals of trivalent and pentavalent, polluted underground water and surface water are enriched with final influence human health by animals and plants.Cause
How this, which effectively removes the organo-arsenic pollutant in livestock breeding wastewater, is concerned.
Into the organic pollutant in environment minimizing technology there are many, such as absorption, advanced oxidation, photocatalytic degradation.
Wherein photolysis is the real decomposable process of Organic Pollutants In Water, affects the toxicity of Organic Pollutants In Water strongly
Become with returning, people conduct extensive research photocatalytic degradation of organic matter in recent years.Nano semiconductor material is in photocatalysis side
The special performance in face, as can carrying out the removal of environmental contaminants, equipment and simple process, strong operability, nothing using sunlight
The features such as secondary pollution, makes it show special advantage in terms of handling toxic, persistent organic pollutants.As a kind of heavy
The conductor photocatalysis material wanted, titanium dioxide have the features such as catalytic activity is high, nontoxic and stability is good, air cleaning,
The multiple fields such as automatically cleaning and wastewater treatment have obtained preferable application.Although TiO2Semiconductor material catalytic activity with higher
And oxidability, good chemical stability and thermal stability, but preparation method is complicated, needs high temperature and pressure, it is at high cost；
And it is less to visible absorption, is unfavorable for utilizing natural light.Therefore people attempt other metal oxide materials such as iron oxygen
Compound etc..
Iron is the element that content occupy the 4th on the earth, is existed in the form of~16 kinds of ferriferous oxides, and ferriferous oxide is extensive
It is distributed in nature.Iron oxide material is synthesized in catalyst, battery material, optical material, pigment, gas sensor and magnetic
Property the fields such as material have and be widely applied.In various iron oxide materials, bloodstone is since its absorbing properties is high, catalytic degradation
Ability is strong, property is stable, synthesis is convenient and simple, source is wide, at low cost, non-toxic, and is more and more paid attention to.Bloodstone
Nano material has extensive in fields such as catalysis material, electrode material, pigment, medicine, gas absorption and water quality purification materials
Using.With TiO2It compares, although nanometer α-Fe2O3Photo-quantum efficiency is not high, but since its energy band band gap (~2.05eV) compares TiO2
(~3.2eV) want narrow, so that it is compared TiO to the absorbing wavelength range (≤560nm) of light2Absorbing wavelength range (380nm) want wide.
Therefore within the scope of ultraviolet visible light region, bloodstone has stronger absorption than titanium dioxide, increases to the utilization efficiency of sunlight
By force.And ferriferous oxide can induce Fenton effect, therefore bloodstone photocatalysis will tool in terms of water body environment pollution object improvement
Have broad application prospects.
In the wastewater treatment of organic pollutant, the advanced oxidation processes research based on potentiometric titrations is concerned.
Other than persulfate (peroxydisulfate, peroxy-monosulfate), sulphite can also generate potentiometric titrations, with persulfuric acid
Salt is compared, and sulphite toxicity is lower, and source is wider, chemical property is stablized, and transport, storage is convenient, cost is lower.And sulfurous acid
Salt is included in by country and drinks water reducing agent catalogue.Metal ion (such as Fe3+、Cu2+、Mn2+With Cr (VI)) and transition gold
Metal catalyst (cobalt ferrite, coppe ferrite) etc. can activate sulphite, potentiometric titrations be generated, to drop to pollutant
Solution.And apply the correlative study of iron oxide material catalytic activation sulphite photocatalytic degradation organic pollutants in water body then less
Report.
Summary of the invention
The purpose of the present invention is in view of the above problems, provide a kind of utilization bloodstone material catalyzed sulfite light
The method of catalytic degradation removal roxarsone.
Its technical solution is that:
A kind of water body roxarsone pollution photocatalytic degradation agent, the degradation agent are made of sulphite and bloodstone.
Preferably, the weight ratio of the sulphite and bloodstone is 0.5~30:1.
Optimal, the weight ratio of the sulphite and bloodstone is 5~10:1.
Preferably, the sulphite is slightly soluble or slightly solubility sulphite, most preferably calcium sulfite.
Preferably, the bloodstone is pure phase nanometer bloodstone.
A kind of water body roxarsone pollution photocatalytic degradation method, method includes the following steps: being polluted to roxarsone
Water body in launch above-described degradation agent, the pH of water body is then adjusted to 4-8, fresh air is finally passed through into water body
And carry out lighting process.
Preferably, the weight ratio of the bloodstone in the degradation agent and roxarsone is 0.5~60:1,
Optimal, the weight ratio of bloodstone and roxarsone in the degradation agent is 5~10:1.
Preferably, the pH of water body is adjusted to 7, or slightly below 7 slant acidity.
The beneficial effects of the present invention are:
The present invention utilizes bloodstone nano material and sulfite ion, realizes to roxarsone organic contamination in waste water
The photocatalytic degradation of object.The present invention has degradation efficiency high, and the time is short, the advantages that using sunlight, and bloodstone material
It can be repeated several times utilization, method is easy to operate, material source is extensive, at low cost, friendly without the generation of poisonous and harmful by-product, environment
It is good, there are the bright prospects for being applied to the processing application of organic polluting water containing roxarsone.
