Description
Technical field
The utility model belongs to textile printing and dyeing pre-treatment technical field of waste water processing, and in particular to a kind of printing and dyeing pre-treatment is useless
The sludge treating system that water process generates.
Background technique
Textile finishing generally can be divided into three phases: pre-treatment, dyeing, final finishing.According to the difference of weaving mode, cotton and
Cotton blend, which knits product, can be divided into tatting product and knitting product.Other than dyeing pretreatment process is slightly different, dyeing and print
Flower process is essentially identical.By taking woven as an example, pretreatment process are as follows: fabric examines → singes → desizing → boiling-off → bleaching →
Mercerized finish.
The process that pre-treatment mainly generates waste water is as follows:
(1) it singes waste water, fabric has to pass through cooling cylinder or water-bath after singing, enable fabric is cooling to restore feel, waste water water
Amount is few.Contained major impurity ingredient is Soft flocks.
(2) desized wastewater, desizing are to remove the process of warp yarn sizing material, the main method for using starch enzyme desizing.Desizing
Waste water accounts for the 20%-35% of pre-treatment workshop total water consumption, and pollution level is relatively high.Contain various slurry degradation objects, fiber
The pollutants such as bits, enzyme, PVA.
(3) scouring and bleaching waste water, boiling-off technique generally use the aqueous solution of caustic soda, surfactant etc., in pH value 10-13(caustic soda
Dosage respectively may be about 40g/L, 80g/L according to fabric is thick and heavy) under conditions of to cotton fiber carry out boiling-off, remove fiber in cotton wax,
The impurity such as grease, pectin.Waste water is in strong basicity, and BOD and COD value are higher.Bleaching process is gone using hydrogen peroxide as oxidant
Except fiber surface and internal foreign pigment.Since hydrogen peroxide almost decomposes in bleaching effluent, the waste water characteristic amount of being is big
But pollution is small, substantially belongs to cleaning waste water.Boiling-off and bleaching process carry out on same board, since workshop bleaching and scouring equipment is discontinuous
Operating, wastewater flow rate are not very big.
(4) mercerizing waste water, mercerized finish use sodium hydroxide concentrated alkali solution (about 200g/L).Mercerizing waste water alkalinity is high,
High alkali liquid is not discharged generally, and use is repeated as many times as required in technique.Company is returned using multi-effect evaporator mercerizing waste water light alkali concentration
Receipts system utilizes concentration recycle of alkali liquor.
Waste water is being removed floating material, suspended material etc. in waste water by pre-treatment waste water treatment system of printing and dyeing by grid pond
Then larger particles impurity enters conditioning tank by pipeline self, installation air-floating apparatus removes to suspend in water body in conditioning tank
Enter first shallow lake pond after grain substance and the water outlet of small fibrous matter, the water outlet injection hydrolysis acidification pool in first shallow lake pond is difficult to degrade by macromolecular
Hydrolysis of organic matter acidification is small molecule degradable material, is sent into anaerobic jar after water outlet, and the biogas that anaerobic jar generates is through desulfurization, de-
Enter gas-holder after water, removing impurities purification and then discharge or burn recycling thermal energy, anaerobic jar water outlet enters contact-oxidation pool and handles, makes
Biomembrane comes into full contact in organic matter and pond in waste water, through microorganism adsorption, degradation, after being purified water quality, and warp
Qualified discharge after water outlet is handled using sand filter after inclined-tube sedimentation tank precipitating is completed at the purification to printing and dyeing pre-treatment waste water
Reason, but handled in wastewater treatment process before above-mentioned printing and dyeing, dirt can be generated in first shallow lake pond, inclined-tube sedimentation tank and anaerobic jar biogas residue
Mud, these sludge need periodic cleaning.It is therefore desirable to design a kind of dirt accordingly with printing and dyeing pre-treatment waste water treatment system
Mud treatment system, with the sludge generated in form sediment at the beginning of easy cleaning pond, inclined-tube sedimentation tank and anaerobic jar biogas residue.
Summary of the invention
