Description
Technical field
The invention belongs to microbial technology field, and in particular to a kind of preparation and processing method for handling aniline waste water.
Background technology
Aniline is the important source material of the industries such as medicine, pesticide, dyestuff, is widely present in the waste water of these industries.Due to
There is very strong toxicity to the mankind and other biologies, so many countries all strictly limit the discharge standard of aniline.It is now raw
Thing is degraded
As the prefered method for removing low concentration aniline in waste water.Under the effort of numerous researchers, people are from ring
The high-efficiency strain of isolated a variety of aniline degradations in border, the path of different bacterium aniline degradation might have difference.
Traditional processing method of phenyl amines sewage generally has：
Physical：(1) absorption method.Absorption method is using the method for sorbing material processing aniline waste water, has recyclable profit
The features such as utilization being repeated with aniline, adsorbent.Tao Hong etc. is using natural rock mineral as raw material, by better simply technical process
The 13X zeolite molecular sieves of synthesis are used for the experimental study of Adsorption of Aniline in Water the result shows that the processing of 13X molecular sieves is given up containing aniline
Water, not only advantages of good adsorption effect, but also power of regeneration is strong, feasibility foundation is provided for actual treatment containing aniline waste water；(2) extract
Method.Extraction is using immiscible with water but energy dissolved contaminants extractants, after it is sufficiently mixed contact with waste water, profit
A kind of purification method for effluent of pollutant is separated and extracted in water with distribution ratio different in solvent with pollutant.Feng Xudong etc.
Mouth has carried out aniline and m-chloroaniline weak solution molten on the basis of organic solvent and complexing agent P204 biological degradabilities is investigated
Agent extraction and the research of complexometric extraction, BOD, COD of extraction raffinate show, select suitable extractant to be extracted, its extraction raffinate
Biological treatment can be carried out without further dilution, demonstrates the potentiality of extraction and displacement ruling by law reason organic wastewater with difficult degradation thereby.
Chemical method：(1) photocatalytic oxidation.Photocatalysis oxidation technique light requirement, catalyst and air, processing cost are opposite
It is relatively low.The H such as Ke Qiang using butyl titanate as raw material, using bentonite as carrier, with acid sol-gel method synthesize TiO nano-complexes, and
Make catalyst using the compound, photocatalytic degradation aniline solution is carried out in the presence of HO.The result shows that the catalyst is in UV/
There is good photocatalytic degradation effect in HO systems to aniline solution, its effect is better than pure TiO.(2) supercritical water oxidation method.It is super
For critical oxidation technology (SCWO) using supercritical water as reaction medium, air, oxygen or hydrogen peroxide etc. are oxidant, pass through height
Radical reaction under warm high pressure, is nontoxic small such as carbon dioxide, water and nitrogen and salt by oxidation operations such as aniline
Molecular compound.A set of simple and practical supercritical water oxidation experimental provision such as Wang Jingchang, to supercritical water oxidation method processing
Waste water from dyestuff containing aniline has carried out experimental study, has investigated the technological parameters pair such as reaction time, temperature, pressure and initial concentration
The influence of degradation rate of aniline.(3) chlorine oxidation process.Chlorine dioxide is in one kind found in 1811 by Han Feilaidaiwei
Strong oxidizer.Yu Deshuan etc. is studied according to the production experiment of certain company's dye wastewater treatment, it is proposed that using chlorine dioxide oxygen
Change the method for removing aniline category matter in waste water from dyestuff.The result shows that：As aniline mass concentration >=50mg/L in sewage, easily
Activated sludge is caused to be poisoned：As aniline mass concentration≤50mg/L in sewage, water outlet can be made using chlorine oxidation process
Aniline mass concentration is down to<2mg/L, removal rate reach 95% or so.(4) sonication.Ultrasonic technique is empty using sound
Change energy acceleration and control chemical reaction improves a kind of new technology of reaction rate, there is removal efficiency height, the reaction time is short, carries
The advantages that biodegradability of high waste water, facility are simple, floor space is small.Fu Min etc. is investigated using aniline solution as research object
Influence to its ultrasonotomography rate of ultrasonic time, aniline solution concentration, pH, the factor such as dosage of oxidant HO the result shows that：
Ultrasonic time is longer, and degradation rate of aniline is higher；Aniline initial concentration is substantially linear with its degradation rate；With the increasing of pH
Big degradeds take the lead in reducing after increasing.The degradation rate highest near pH=7.3；(5) electrochemical degradation method.Electrochemical degradation is to pass through
The direct degradation of organic substances of anode reaction, or by anode reaction produce hydroxyl radical free radical, ozone class oxidant degradation of organic substances,
It is more thorough that this degradation pathway decomposes organic matter, is not likely to produce murder by poisoning intermediate product, more meets the requirement of environmental protection.King
Beautiful tinkling of pieces of jade etc. have studied the electrochemical degradation characteristic using SiO2/Ti as anodic degradation aniline.
The water body treating of amino benzenes compounds pollution is more difficult, and studies in China is less, and up to now, the overwhelming majority uses
Physics, chemical method are pocessed, but these method processing costs are higher, and technical requirements are more stringent, difficult in practical application
To promote.
Bioremediation is to administer the effective ways of amino benzenes compounds polluted-water.It is the work using microorganism
With being decomposed amino benzenes compounds.Since bioremediation is more much lower than physics, chemical method cost, and without secondary
Pollution, and microorganism has stronger variability and adaptability again, therefore it has become processing amino benzenes compounds contaminant water
The ideal method of body.Amino in aniline is converted to inorganic ammonia first.If these ammonia cannot handle and flow directly into river
Stream, then easily lead to river eutrophication.Biological nitration, biological denitrification method are to handle one kind of low-concentration ammonia-nitrogen in water
Very effective method.Aerobic nitrification is exactly in the presence of oxygen, to pass through nitrite bacteria and nitrobacteria
Collective effect, nitrate anion is finally oxidized to by ammonia through peroxynitrite.Therefore, develop a kind of construction investment is few, operating cost is low,
The sewage disposal technology of good treatment efficiency is extremely urgent.
