Abstract
A treating agent comprising two polyelectrolyte components A and B and one surfacant component C is used as treating medium. In waste water containing dye, the treating agent interacts to form water insoluble copolymer capturing dye, assistant and other organics in water solution. Using the said method in treating waste water has an eliminating rate of 98-100% for dye and of 96-99% for other organics.
Description
The present invention relates to a kind of water treatment method, particularly a kind of purifying treatment method about printing and dyeing industrial waste water.
At present, the purifying treatment to dyeing waste water, waste water from dyestuff adopts chemical coagulation-sedimentation method more.The employed medicament of this method is generally inorganic salts coagulating agent and high-molecular coagulant adopting and coagulant aids thereof etc.The inorganic salts coagulating agent is owing to the quality instability, and the medicament usage quantity is bigger, and the discharging waste residue is more, separates not exclusively, and treatment effect is relatively poor.Traditional high-molecular coagulant adopting and coagulant aids method thereof when containing large amount of organic in waste water, need to throw in more coagulating agent, and this coagulating agent influence factor complexity are difficult to control, so treatment effect is also not satisfactory.
The present invention is intended to overcome the deficiency that exists in the above-mentioned big system treatment process, provides that a kind of dosage is few, lock out operation is convenient, the purifying process of waste water containing dye that purifying treatment is effective.
Technical scheme of the present invention is on the basis of the advantage of drawing the polymer coagulant sedimentation, according to dyeing waste water inherent characteristic, utilization has intensive chemistry and the physisorption that interacts between the polyelectrolyte of opposite charges and produced with anti-charged surface promoting agent complexing action, can intercept and capture the performance of dye well dyeing and printing auxiliary in the aqueous solution to greatest extent, to reach the treatment effect of waste water from dyestuff the best.
The key problem in technology of purifying process of waste water containing dye of the present invention is to have adopted the special processing agent as its treatment media.This treatment agent,, perhaps is made up of component A and component C perhaps by component B and component C perhaps by component A+ component B and component C component A and component B.Component A and component B are the polyelectrolyte of oppositely charged, and component C is a tensio-active agent.Component A, B can be respectively the ionic polyacrylamide of oppositely charged or one or more the polyelectrolyte in polyacrylic acid or sodium polyacrylate or hydrolyzed polyacrylonitrile or polymerization dimethyl diallyl ammonium chloride or the sodium carboxymethyl-cellulose, component C can be the hexadecyl pyridinium bromide, or hexadecylpyridinium chloride, or dodecyl bromination pyridine, or dodecyl chlorination pyridine, or alkyl halide pyridine, or 1631 cats product, or 1831 cats product, or Sodium dodecylbenzene sulfonate, or calcium dodecylbenzene sulphonate, or alkyl sodium sulfonate, or emulsifying agent PP2, or among the emulsifying agent S-118 one or more.When forming treatment agent by component A and component B, its proportioning is: the content of component A is 20-80%, and all the other are component B.When forming treatment agent by component A+ component B and component C, its proportioning is: the content of component A+ component B is 30-99%, and all the other are component C.When forming treatment agent by component B and component C, its proportioning is: the content of component B is: 30-99%, all the other are component C.When forming treatment agent by component A and component C, its proportioning is: the content of component A is: 30-99%, all the other are component C.
In carrying out the waste water from dyestuff decontamination process, the polyelectrolyte treatment agent of the oppositely charged of being made up of component A and component B interacts in waste water solution, when gathering complex compound in forming, absorption is is also intercepted and captured dyestuff, when the tensio-active agent with component C interacts, can form polymkeric substance again--the colloid complex compound makes the organic matter removals such as dye well dyeing and printing auxiliary in the aqueous solution more complete.Water-fast jelly then is suspended in the water surface, separate easily, and these jellies soak for some time in electrolyte solution, can separate wash rice, reclaim dyestuff.Dyestuff clearance in the waste water can reach 98-100%, and other organic clearances also can reach more than 96%.
When reality uses treatment agent to carry out the waste water from dyestuff purifying treatment, also must understand the organic content situation of dye well in the waste water from dyestuff, so that select best purification process and best treatment agent usage quantity.In the ordinary course of things, the pure consumption of treatment agent and the dyestuff weight ratio in the waste water from dyestuff are controlled at 0.1-5: in the time of in 1 the scope, waste water from dyestuff can reach the ideal treatment effect.
Embodiment 1:
Acid brilliant yellow 2g (C.I.Acid yellow 17) waste water from dyestuff purifying treatment:
Treatment agent preparation: A component: anion-polyacrylamide 0.2% (weight) aqueous solution
C component: hexadecyl pyridinium bromide 0.5% (weight) aqueous solution
Dyestuff starting point concentration in the waste water from dyestuff: 0.05% (weight)
Operation: in the 1000ml beaker, add 500ml concentration and be 0.05% waste water from dyestuff, stir with electric blender and add the C component with experiment, stirred for 30 seconds after, add the A component again, continue stirred for several minute, contain the dyestuff jelly and separate out fully, the water layer clarification, jelly is fished for separation.A component consumption is 22ml, and C component consumption is 10.5ml.
The result: the clarification of water liquid, water white transparency is with the check of ultra-violet absorption spectrum instrument, dyestuff clearance 〉=99.5%, other organic removal rate 〉=98.3%.
Embodiment 2:

Process object: printing and dyeing mill's wastewater disposal basin dyeing waste water contains 2 basic orange 2, Acid Red G, the composite waste of multiple dyestuff such as DISPERSE YELLOW.
Operation: 3m
3Wastewater disposal basin in stir process, the time is 6 minutes
The result: the water surface floats the jelly that contains dyestuff, after separating with net, and the water layer clarification, colourless.After measured, the water quality after the processing, dyestuff clearance 〉=99.8%, other organic removal rate 97.5%.
