Problems solved by technology

[0002] Due to the needs of the production process, the printing and dyeing workshop must discharge a certain amount of waste water, which contains a large amount of organic matter, chroma, sulfide, dyes and some auxiliaries, alkali, etc. The direct discharge of these waste water without any treatment is bound to cause serious damage to the surrounding environment. Serious pollution is caused. The selection of sewage treatment process is the key to the construction of printing and dyeing sewage treatment project. Whether the treatment process is selected properly will not only affect the treatment effect, but also affect the infrastructure investment of the entire treatment project, the reliability of the treatment process operation, and the operation cost. and the complexity of managing operations

Abstract

The invention discloses a clothing dyeing wastewater treatment process. The process comprises the steps of filtering, decolourizing, performing flocculoreaction, and performing solid-liquid separation, wherein a decolourizing agent A and a decolourizing agent B are added while decolourizing; the decolourizing agent A is prepared from potassium permanganate and polymeric ferric sulfate at a ratio of 1:1, and the decolourizing agent B is prepared from tripolycyanamide, oxalaldehyde and ammonia chloride at a ratio of 10:2:3. The processing method provided by the invention has the characteristics of simple and practical, convenient management, strong operation stability, small maintenance workload, wastewater quality adaption and big moisture change. The processed discharged water quality reaches the Wastewater Pollutants Discharge Standard for Textile Printing Industry.
