Description
Technical field
The present invention relates to waste water treatment process, more particularly to a kind of resin adsorption method pretreatment contains benzene
Amine waster water process.
Background technology
Current BTA is mainly synthesized using o-phenylenediamine with natrium nitrosum by a step compressive reaction, and TTA is mainly use
Methyl-o-phenylenediamine is synthesized with natrium nitrosum by a step compressive reaction.But in process of production can generating structure complexity, color and luster
The deep, organic pollution that easily biological-degradable, bio-toxicity be not big, biodegradability is poor, makes the phenyl amines content in waste water sometimes high
Up to 8000-10000mg/L.Amino benzene analog waste water generally has the characteristics that：
(1) pollutant is complicated, concentration is high
This kind of general pollutant of waste water is complicated, and the solubility in water is big, thus this kind of waste water concentration and COD in water
In thousands of to tens of thousands of mg/L.
(2) salt content is high
The amino benzene analog waste water of source organic synthesis is typically all containing inorganic salts such as NaCl, NaSO4, sometimes at concentrations up to 20-30%.
(3) waste water acid（Alkali）Property is strong
(4) color and luster is deep
Aniline category matter all also has chromophoric group amido, easily occurs metachromasia in reaction, generation colourity very high product.
（5）It is not readily biodegradable
Aniline category matter typically has cyclic structure, quite stable, it is difficult to biodegradable.BOD/COD of the aniline category matter in water
Value is relatively low, typically has growth inhibition effect to microorganism, biodegradability is poor, and preferable effect is reached with conventional biochemical method difficulty
Really.
（6）Bio-toxicity is big
Amino benzenes compounds accessory has higher bio-toxicity, to have teratogenesis or the material of carcinogenesis to biological or microorganism,
Harm to the human body is very big.Thus amino benzenes compounds are the toxic organic compounds forbidden or strictly controlled in environment, are state controls
A class compound.
Due to the difference of the composition containing amino benzene analog waste water, acid-base property and concentration, processing method is also different, at present industrial place
Method of the reason containing amino benzene analog waste water is generally divided into extraction, oxidizing process, biochemical process, electrolysis, supercritical ultrasonics technology and absorption method, in addition
Also burning method, froth flotation method and azeotropic distillation method etc..
Although the method for handling amino benzene analog waste water is more, more or less also there are some defects in most of method.For example,
Using extraction processing method, extractant, which is easily lost in, causes secondary pollution, while energy consumption is higher, operates complex；Advanced oxidation
Although substantially, reaction condition is more harsh for method effect, operating cost is high；Active carbon adsorption or organic clay absorption method, inhale
Attached dose of regeneration is more difficult；Electrolysis energy consumption is big, and cost is high；Biological treatment floor space is big, and low temperature aging rate is low, dense by waste water
Degree influence is big and operational management is more bothered；Sonication energy consumption is big, and noise is serious, whether economical handles substantial amounts of waste water
Also need to further research；Burning method energy consumption is big, high to equipment requirement, and the imperfect combustion thing and smoke dust that produce are caused
Certain atmosphere pollution.
The content of the invention
Technique containing amino benzene analog waste water is pre-processed the technical problem to be solved in the present invention is to provide a kind of resin adsorption method, is passed through
Resin adsorption method is adsorbed to the aniline in amino benzene analog waste water, the processing method, again may be used while processing effective to waste water
Realize that changing waste into resources is reclaimed.
In order to solve the above technical problems, the technical scheme is that：A kind of resin adsorption method pretreatment is useless containing phenyl amines
Hydraulic art, its innovative point is：The technique comprises the following steps：

Waste water in level filter feeding prime raw wastewater tank, raw wastewater tank is again through delivery pump with 1~3m3/ h flow delivers to accurate mistake
Filter, filters out mechanical admixture；
（2）After mechanical admixture is filtered out, then continuously entered to the first resin adsorption tower and the second resin adsorption tower successively by circulating pump
Waste water, and 1~3m of control flow3/h；Two-stage is passed through by the resin column in adsorption tower containing aniline waste water into resin adsorption tower
Continuous absorption, the aniline in waste water is adsorbed above；
（3）After resin adsorption, by pretreated waste water by waste water pump with 1~3m3/ h flow feeding treatment tank,
Resin column after the completion of processing carries out activation process, recycles.
Further, the step（2）In resin column be DA201-C types resin column, NKA
One kind in -2 type resin columns or H-103 type resin columns.
Further, the step（3）Middle resin column carries out concretely comprising the following steps for activation process：（1）Blown with compressed air
Remaining waste water is to storage tank in dried resin post；（2）By pump pre-configured methanol solution is continuously introduced into after emptying to be activated
Resin column, it is desirable to flow control in 1m3/ h, is cleaned to resin column, and flushing dose is controlled in 1m3/h；（3）Methanol cleaning knot
Shu Hou, is blown the methanol in resin column with compressed air；（4）Rinse water is sent into resin column with pump again and circulated, the first tank
After having circulated, the circulation of the second tank is played, the 3rd tank is then played, is cleaned by gradient, one is reached by test when the first tank alcohol is remained
Determine after concentration, deliver to distillation still and recycled；（5）After cleaning terminates, resin column is dried up with compressed air, activation is completed,
Standby lower batch is used again；（6）Recovery kettle is delivered in cleaning activation with methanol solution, and methanol is reclaimed by Distallation systm with steam, is returned
Receive methanol and enter receiving tank.
The advantage of the invention is that：
（1）Resin adsorption method of the present invention pre-processes technique containing amino benzene analog waste water, and waste water is first passed through into grade one filter carries out just mistake
Filter, after prefiltration, then is filtered by accurate filter, filters out mechanical admixture, be easy to the resin adsorption in later stage to handle；And it is useless containing aniline
Water is continuously adsorbed by the resin column in adsorption tower by two-stage, and then may further ensure that aniline by resin adsorption, Neng Gouyou
Effect removes the aniline in waste water, it is to avoid pollution；Meanwhile, the resin column after the completion of processing carries out activation process, and waste money can be achieved
Sourceization is reclaimed.
（2）Resin adsorption method of the present invention pre-processes technique containing amino benzene analog waste water, and there is its macroreticular resin used absorption to imitate
Really good, desorption and regeneration is easy, performance is stable, applied widely, practicality is good, can be achieved comprehensive utilization the features such as, and then cause
The cost of wastewater treatment is low and high treating effect.
（3）Resin adsorption method of the present invention pre-processes technique containing amino benzene analog waste water, wherein, the activation process of resin column uses first
Alcohol processing, one be methanol cost it is low, furthermore be processing after methanol can also be recycled.
