Background technology
In recent years, the improvement of waste water from dyestuff has become one of study hotspot of water treatment field.In early days, conventional dyestuff
Method of wastewater treatment mainly says solution including flocculent precipitation, chemical oxidization method, membrane separation process and biology.Although these methods can
To reduce the content of dyestuff in waste water from dyestuff to a certain extent, but still there is it is of all kinds the defects of, for example, because of absorption
Rate is low, processing cost is too high and the bad adaptability to waste water from dyestuff composition transfer, result be it is not good enough to the removal effect of dyestuff, separately
It is also possible to that poisonous and harmful accessory substance or a large amount of sludge can be produced in external processing procedure, so as to cause secondary pollution.
The content of the invention
It is an object of the invention to provide a kind of adsorption effect significantly and will not produce secondary pollution waste water from dyestuff compounding
The preparation method of adsorbent.
The technical solution for realizing the object of the invention is：
A kind of preparation method of waste water from dyestuff compounding adsorbent, comprises the following steps:By the uniform of chitosan and activated carbon
Glacial acetic acid is added after mixing, add glutaraldehyde after stirring swelling a period of time is stirred crosslinking in water bath with thermostatic control, then uses
Sodium hydroxide solution is washed, and removes remaining glutaraldehyde, is washed, is dried, mills, sieving finally obtained required cross-linking type
Chitosan/activated carbon；Wherein, chitosan, activated carbon, glacial acetic acid three mass ratio are 8~6 in the preparation method:3~2:1.
The concentration of the sodium hydroxide is 25-35mg/L.
The concentration of glutaraldehyde described in the preparation method is 5-30mg/L.
The mixing time is 2-3h.
The bath temperature is 40-50 DEG C.
Compared with prior art, its remarkable advantage is the present invention：
Preparation method technique of the present invention is simple, obtained chitosan/activated carbon compounding adsorbent, is inhaled using physics and chemistry
The attached mode being combined carries out adsorption treatment to waste water from dyestuff, and adsorption effect is notable, effectively raises the clearance of waste water, place
Secondary pollution will not be produced after reason, is had a good application prospect.
