Abstract
The invention relates to waste water treatment agent particular to gravure waste water, which comprises: iron coagulant 10-60%, dispersant 5-30%, defoaming agent 1-10%, cosolvent 3-5%, and water. The formulation brings well coagulate effect to ink-contained waste water from product or ultrafiltration. The mud-water can be separated by pressure filter. This agent has stable water-phase, well compatibility with waste water.
Description
Technical field
The present invention relates to a kind of waste water conditioner, refer to a kind of bank-note gravure printing waste water conditioner and treatment process especially.
Background technology
Wiping version liquid in the seal paper money process, to clean the formed printing ink waste water that contains of look mould roller be one of difficulty of being faced of seal paper money industry.This wiping version liquid major ingredient: sodium hydroxide 1.0-1.2%, tensio-active agent are about 0.5, softening water and other auxiliary agents 98.3%-98.5%; Contain printing ink waste water major ingredient: pigment, weighting material, connection material, resin oils, tensio-active agent and sodium hydroxide.
At present comparatively feasible treatment process is: see Fig. 1, contain printing ink waste water through in coagulation, ultrafiltration technology after, through air supporting, carry out aftertreatment at last.In and in the coagulation workshop section, adopt pH that the sulfuric acid about 50% regulates waste water to neutral substantially, add a certain amount of polymerize aluminum chloride then and carry out coagulating treatment.Supernatant enters subsequent disposal workshop sections such as air supporting after the static sedimentation, and the water suspension of sediment carries out the external coordination burning disposal.The disadvantage of present processing means:
1. the dilution of the vitriol oil is a kind of very dangerous work.Very exothermic in vitriolic corrodibility and the dilution is brought serious harm to the staff.
2. the difficult control of the thermopositive reaction of sulfuric acid in the process of regulating pH, violent chemical reaction can cause the excessive of waste water, badly influences Working environment, and brings certain body and mind injury to operator.
3. the sediment viscosity after the coagulating treatment is bigger, can not enter pressure filter and carry out the press filtration processing.The common water ratio of the incinerated matter of external coordination is bigger, and processing cost is higher.
4. settled weak effect need carry out air supporting and handle away suspended substance in the water body, has increased processing cost and energy consumption.
5. the settlement separate time is long, has reduced working efficiency.Automatic continuous production can not be accomplished simultaneously.
After improving, as number of patent application: a kind of waste water treatment agent for novel gravure note printing of 031157661, can carry out solid-liquid separation preferably, but still have certain defective: the water consistency as medicament is poor, can not obtain stable gravure printing waste water treatment agent, simultaneously, original medicament in use can produce a large amount of foams, uses traditional ethers defoamer can not press down the bubble effect effectively.
Summary of the invention
The object of the present invention is to provide a kind of stable water-soluble treatment agent formula, make it can in coagulant precipitation workshop section, under the condition that does not add acid, improve the coagulant precipitation effect.
A kind of waste water treatment agent for novel gravure note printing of the present invention, this treatment agent formula comprises: ferric flocculant 10～60%, dispersion agent 5～30%, defoamer 1～10%, solubility promoter 3～5%, all the other are water, wherein, described ferric flocculant is a bodied ferric sulfate, ferrous sulfate, a kind of or its combination in the PFAS; Described dispersion agent is a polyacrylic acid, polyacrylic ester, a kind of or its combination in the polymaleic acid; Described defoamer is a nonionogenic tenside, and described solubility promoter is the polyamine class, comprises poly-divinyl propyl-dimethyl ammonia chloride, a kind of or its combination in the polydimethyl amine vinyl acrylate etc.
On the such scheme basis, tensio-active agent of the present invention is an organic silicone oil, polyoxyethylene glycerol ether, polyoxyethylene polyoxy third rare tetramethylolmethane ether, the composition of one or more in the polyoxypropylene ethylene oxide glyceryl ether.
The treatment process of a kind of waste water treatment agent for novel gravure note printing of the present invention wherein, adds treatment agent 3.5% of the present invention under the condition of 300r/min, churning time is 5 minutes; Under the condition of 150r/min, add polyacrylamide (1 ‰ concentration) 5 ‰.Churning time 3 minutes; Waste water after will handling by sludge pump is squeezed into plate and frame(type)filter press and is carried out press filtration and handle 10 minutes press filtration treatment times.
The treatment process of the another kind of waste water treatment agent for novel gravure note printing of the present invention wherein, adds this treatment agent 12% under the condition of 300r/min, churning time is 5 minutes; Under the condition of 150r/min, add polyacrylamide (1 ‰ concentration) 1%, churning time 3 minutes; Waste water after will handling by sludge pump is squeezed into plate and frame(type)filter press and is carried out press filtration and handle 7 minutes press filtration treatment times.
Superiority of the present invention is: the present invention's prescription contains the concentrated printing ink waste water that contains that obtains after printing ink waste water and the ultrafiltration to the board that produces in producing all good coagulating treatment effect, and the mud-water separation after the coagulating treatment can be accomplished by pressure filter simultaneously.Show following several respects:
1. in use need not to add acid and regulate, avoided acid, reach the purpose of safety in production the corrosion of equipment and injury to operator.
2. reacting balance in treating processes does not have the obvious thermopositive reaction that gets, and need not to carry out special process control.
3. coagulant precipitation is effective, and the treatment time is short.Handling the resulting mixture in back does not have tangible viscosity, can utilize water extracter to carry out corresponding mud-water separation.Be used corresponding organic coagulant aids and can further improve the dehydration rate of filter cake.
4. the water good stability of medicament is good with the consistency of waste water.Can carry out the wastewater treatment reaction quickly, effectively raise processing efficiency.
5. through after the processing of this medicament, the supernatant liquor suspension content that obtains is low, can remove auxiliary workshop sections such as air supporting in treatment process, reduces processing cost.
