Problems solved by technology

[0003] At present, in order to improve dyeing efficiency and dyeing uniformity, jet dyeing technology has been gradually used to dye cotton fabrics, etc., wherein, in the process of jet dyeing cotton fabrics, sewage will be produced, and now people usually directly discharge, but this not only pollutes the environment, is not environmentally friendly, but also wastes water resources. Therefore, it is urgent to set up a device that can recycle and purify sewage to solve the above problems

Embodiment 1

[0022] The present invention also provides a method for treating jet dyeing wastewater by adopting the above-mentioned high-pressure water-saving jet dyeing sewage recovery system for all-cotton fabrics, and the specific steps are as follows:

[0023] Add chlorine dioxide to the disinfection tank, add coagulant to the coagulation tank, and add activated carbon to the adsorption tank. Dyeing sewage is first discharged into the filter tank. The grille in the filter tank will remove the yarn ends and cloth pieces in the dyeing sewage. The dyeing sewage flows from the filter tank into the disinfection tank. The chlorine dioxide in the disinfection tank disinfects and sterilizes the harmful substances in the dyeing sewage. The disinfected dyeing sewage enters the coagulation tank through the disinfection tank, and the coagulant in the coagulation tank will The dye and detergent in the dyeing sewage are combined into large particles to be removed, and then the dyeing sewage flows from t...

Description

Technical field [0001] The invention relates to the technical field of textiles, in particular to a high-pressure water-saving jet dyeing sewage recovery system for all cotton fabrics. Background technique [0002] Printing and dyeing is also called dyeing and finishing. It is a processing method, and it is also a general term for pre-processing, dyeing, printing, finishing, washing and so on. The undergraduate dyeing and finishing major has now been merged into the light chemical engineering major. In the Neolithic period years ago, our ancestors were able to dye linen cloth red with hematite powder. The primitive tribes living in the Nuomuhong area of ​​the Qaidam Basin in Qinghai were able to dye their wool into yellow, red, brown and blue. In the Shang and Zhou Dynasties, dyeing technology continued to improve. In the palace handicraft workshops, there were full-time officials "dyers" who came to "palm the grass" to manage the dyeing production and the dyed colors keep growi...
