Description
Technical field
The invention belongs to environmental protection technical field, in particular to a kind of raising stamp pulp thickening object prepares adsorbent suction
The preparation method of attached performance.
Background technique
Ink is made of pigment, binder, filler, additional material etc., can be divided into oil-based ink and water-based ink.Oiliness oil
Contain a large amount of organic solvent in ink, it is seriously polluted, gradually it is eliminated.Water-based ink mainly by water-soluble resin, pigment, alcohol,
Amine or ammonia and other additives and water composition.Water-based ink is wide in every field because of its health, environmental protection, safe characteristic
General application.Currently, a large amount of plastic package material uses water-based ink in stamp, printing more and more, in replacement color
When need to clean printing equipment and water-based ink storage tank, produce a certain amount of high concentration aqueous's ink jet printing waste liquid.This kind print
Containing pollutants such as pigment, water soluble acrylic resin, alcohol, amine (ammonia) in flower waste liquid, content of organics is more, and coloration is high, dirty
Dye it is extremely serious (coloration: 30,000 times or more, CODCr: 100,000-50 ten thousand mg/L), it is difficult to it handles.
Processing for this kind of waste liquid generallys use the chemical methodes such as Coagulation Method and is pre-processed, i.e., adds into waste liquid
Coagulant makes pollutant agglomerate to form sludge, then rolls filter, belt type dewaterer or centrifugal dehydrator etc. using sheet frame and carry out machinery
The solid-liquid separating methods such as dehydration are separated by solid-liquid separation, and water outlet carries out other chemistry or biological treatment to qualified discharge again.Due to useless
Pollutant concentration is high in liquid, and the sludge solid content of formation is up to 5-10%, it is difficult to dehydration, and by mechanism filter-pressing or from
The mud cake formed after heart dehydration carries out landfill disposal usually as solid waste, be easy to cause secondary pollution.
In recent years, domestic and foreign scholars to using various wastes prepare adsorbent and for dye waste water adsorbing and discoloring carry out
A large amount of research.Such as Su Shiung Lam utilizes orange peel in microwave-assisted lower obtained adsorbent, to the balance of peacock green
Absorption property is up to 28.5 mgg-1；Adsorbent is made using plant residue in Alejandra Alicia etc., to acid dyes
Equilibrium adsorption performance with basic dye is respectively up to 312.5 mgg-1With 500.0 mgg-1；Ta í sL Silva etc. utilizes work
Industry washs sludge and adsorbent is made, to reactive dye brilliant blue R equilibrium adsorption performance up to 36.5 mgg-1；Syieluing
Adsorbent is made using weaving sludge in Wong etc., and the equilibrium adsorption performance to active black and methylene blue is respectively 5 mgg-1
With 3.66 mgg-1；Adsorbent is made using leather-making mud in Geethakarthi A etc., measures it and inhales to the balance of REACTIVE RED 31
Attached performance reaches 39.37mgg-1；Adsorbent is made using paper mill sludge in Li Wenhong etc., inhales to the balance of Reactive Red 24
Attached performance is up to 15.68 mgg-1.Adsorbent is prepared with trade waste, not only prevent secondary pollution can be realized solid waste again
Resource utilization, have good environmental benefit and social benefit.But with the absorption of adsorbent prepared by trade waste
Performance is affected by raw material, and the adsorption effect of sludge base adsorbent is generally far below plant base adsorbent, the absorption to dyestuff
It is clearly present the low problem of equilibrium adsorption performance.
Containing a large amount of organic matter available resources such as water-based acrylic resin in water-based ink sludge, as being prepared
At adsorbent and be applied to it is dye decolored, the secondary use of sludge may be implemented." a kind of high concentration is black printed useless for patent of invention
The method that liquid pollutant is extracted and utilized " (number of patent application CN201610904367.5) summary of the invention is " by high concentration black
The acidification of water-based ink stamp waste liquid, stirring make pollutant agglomerate to form paste sludge；The 100- of 5-10g/L is added into sludge
Sludge is heated to 50-90 DEG C of dehydration while stirring after mixing evenly by 500 mesh calcium miberal powders, is made sludge curing at bulk, is deviate from water
Discharge；Take out sludge hot squeeze to moisture percentage in sewage sludge it is dry lower than after 40%；Sludge isolation air after drying is heated to 400-
700 DEG C of heat preservation 1-4h；Sludge is cooled to 50 DEG C or less and is broken into graininess, the misty profit that sprinkling mass concentration is 0.1-0.2%
It is uniformly mixed after humectant solution；Mud granule is added in cationic dyeing waste water by 2-10g/L waste water dosage, is aerated
10-120min, precipitating or filtering removal mud granule are stirred, decolourize discharge of wastewater；Mud granule recycles 400-700 DEG C of heat again
It is raw, it is recycled." it is used for cationic dyeing waste water decoloring adsorbent dosage as 5-10g/L waste water.Such as embodiment
1 " is slowly added to 92% concentrated sulfuric acid into the high concentration black water ink jet printing waste liquid that COD is 39.2 ten thousand mg/L, stirring makes dirt
Dye object agglomerates to form sludge；The 200-500 mesh calcium miberal powder that 8g/L is added into sludge, after mixing evenly while stirring adds sludge
Heat makes sludge curing at bulk, takes off Chinese effluent to 75 DEG C of dehydrations；Take out sludge hot squeeze to moisture content it is dry lower than after 40%；
Sludge isolation air after drying is heated to 500 DEG C of heat preservation 2h；Sludge is cooled to 50 DEG C or less and is broken into graininess, is sprayed
It is uniformly mixed after the misty wetting agent solution that mass concentration is 0.1%；Mud granule is added to yellow sun by 5g/L waste water dosage
In ionic dye dyeing waste-water, aeration stirring 100min, precipitating removal mud granule, decolourize discharge of wastewater, yellow cationic dye
Material dyeing waste-water decolorizing rate reaches 99.5% or more." its adsorbent dosage be 5g/L waste water, hence it is evident that there are adsorbent adsorptivities
It can low, the big defect of adsorbent amount.
If the absorption property of prepared adsorbent can be improved, adsorbent amount can be greatly reduced, save the cost, at raising
Effect is managed, overcomes adsorbent absorption property during cationic dyeing waste water adsorbing and discoloring low, adsorbent amount is big to be lacked
It falls into.
