Abstract
The invention discloses a method for demulsifying and purifying waste emulsion produced by dyeing high-end ribbons, which belongs to the technical field of environmental protection. Due to the demands of the high-end ribbons on the quality, dyeing agents used in the dyeing process are very complicated, and the waste emulsion formed after dyeing is very stable. Proper amounts of H2SO4, 30% of H2O2 water solution and FeSO4 powder are gradually added during the method, thereby thoroughly demulsifying the waste emulsion. CODcr of the waste emulsion before the demulsification is about 0.3 million mg/L, and the CODcr after the demulsification is reduced to about 250mg/L. Substances after the demulsification are dense porous floating matters, the integrity is small, and the substances are easy to separate with water. The raw materials of the H2O2 and the FeSO4 powder used in the method for demulsifying the waste emulsion produced by dyeing the high-end ribbons are easy to obtain, and the method further has the advantages of low cost, simple processing method and easy industrial use.

Technical field
The present invention relates to a kind of method for demulsifying and purifying of waste emulsified mixture of produced by dyeing high-end ribbons, belong to environmental technology field.
Background technology
In security systems such as high-grade car, ship, aircraft, all can use high-quality securing band.It requires, and material is firm, color and luster is attractive in appearance and prolonged can not fading.In these high-quality ribbon production processes, behind colouring, infrared preliminary drying, electrically heated fixation, decatize, washing, starching supervisor, all can form a kind of dyeing waste emulsified mixture.This emulsion major ingredient is as shown in table 1 below.
The major ingredient of table 1 waste emulsified mixture
This kind emulsion stable in properties, any chemical transformation can not take place in long storage time.After measured, the CODcr of this waste water is up to 300,000 mg/L, and BOD
5Approach 0mg/L, biodegradability can extreme difference.Therefore, need a kind of feasible breaking method, its stability is destroyed, be convenient to subsequent disposal, to reduce the harm to environment of this kind emulsion.
Method for demulsifying and purifying commonly used at present has following a few class:
1, coagulating agent breakdown of emulsion utilizes the coagulation mechanism of coagulating agent, makes the emulsified particle in the emulsion make stability.
2, acid out breakdown of emulsion under low pH, makes emulsified particle make stability.
3, pyrolysis breakdown of emulsion by heating, makes the outer moisture film attenuation of emulsified particle, thereby emulsified particle is taken off surely.
4, strong oxidizer breakdown of emulsion utilizes the effect of some strong oxidizers, destroys the emulsified particle structure, thereby it is taken off surely.
Methods such as coagulating agent breakdown of emulsion, acid out breakdown of emulsion, pyrolysis breakdown of emulsion are relatively poor to this kind waste emulsified mixture demulsification, the key issue of strong oxidizer breakdown of emulsion then is 1. to seek suitable strong oxidizer, 2. determine dosing method and dosage, 3. how breakdown of emulsion just can be beneficial to breakdown of emulsion product and aqueous phase separation.The present invention is directed to these problems, a kind of method for demulsifying and purifying of produced by dyeing high-end ribbons waste emulsified mixture is provided.
