Description
Technical Field
The utility model relates to an industrial wastewater treatment and recovery technology in general. More particularly, the present invention relates to a technique and related equipment for treating and recovering waste water generated in the production of brush filaments or monofilaments.
Background
With the stricter of the national environmental protection policy, the wastewater is treated well, and the discharge reaching the standard becomes more important. However, in the production and manufacturing process of monofilaments or filaments for daily use such as toothbrushes, chemical sharpening treatment is often required for the monofilaments or the tips of the filaments, and a large amount of waste water is discharged after the treatment. Because a large amount of sodium phthalate, butanediol and other substances in the wastewater after the transformation are brought into the wastewater by the alkali liquor, if the wastewater is directly discharged, the environment is seriously influenced. Moreover, the local government now sets relevant standards for the pollution discharge of enterprises, and under the urgent need, the treatment, even the recycling of the waste water generated in the production of the brush wire or monofilament is inevitable.
Chinese patent (No. CN101993164B) relates to a method for treating and recovering waste water generated during sharpening polybutylene terephthalate (PBT) brush wires, which is mainly characterized in that the waste water is treated by activated carbon and then filtered to obtain clear waste water, dilute hydrochloric acid is added into the clear waste water to ensure that the pH value is between 3 and 5.5, sodium terephthalate in the clear waste water is converted into white flocculent precipitate of the terephthalic acid, and the white flocculent precipitate is filtered, washed and dried to obtain the terephthalic acid with the purity of more than 99.5 percent; then, neutralizing and filtering the wastewater by using NaOH aqueous solution until the pH value is 7, and layering 1, 4-butanediol and the generated NaCl solution by using a salting-out principle and a redistilling technology to obtain the 1, 4-butanediol with the purity of more than 99.7 percent; after NaCl solution exchange desalination, the water can be used as cleaning water for sharpening the PBT brush wires. However, this patent is only concerned with the treatment of waste water generated when a polybutylene terephthalate (PBT) brush wire is sharpened; and the technical proposal does not relate to the treatment of the precipitated feed. Furthermore, there is no solution to the need for further treatment of wastewater involving multiple cycles due to increased salinity.
Therefore, with the strictness of national environmental protection policies, the wastewater is treated well, and the discharge reaching the standard becomes more important. Various process waste water and washing waste water are generated in the production of monofilaments or brush wires, so that in order to solve the above problems and other problems in the prior art, a new waste water treatment equipment arrangement and process need to be designed, thereby achieving the standard of urban waste water recycling-quality of industrial water (GBT 19923-2005).
The prior art has no treatment and automatic management equipment for treating and recycling waste water in the production of the brush filaments or the monofilaments.
The applicant of the present application, after continuous research and design and repeated debugging treatment, finally designs wastewater treatment and recovery equipment and corresponding process method meeting the minimum waste discharge treatment, even zero discharge.
