Abstract

The problem of sewage treatment with the content of organic dyes is urgent now. Existing dyeing and finishing textile industries are not efficient and highly profitable. Wastewater enters a large number of unused dyes, which cause significant damage to the ecological system of the water region. That is why the problem of reuse of wastewater in technological processes of textile production (dyeing of fabric) and deep purification of wastewater of this production is urgent. The article presents the results of the analysis of sewage dyeing and finishing textile production after averaging and dilution, as well as production sewage immediately after the fabric dyeing process (at the outlet of the dyeing plant). Based on the obtained results, the technology of wastewater treatment of dyeing and finishing production containing organic dyes is proposed, using the processes of filtration, coagulation and flocculation in the cavitator, flotation and electroactivation for the development of effective technology of water cycle and reuse of industrial processes textile production. The results of sewage research are obtained at the cascade type pilot plant, the stages of which have been located above the sump of the existing sewage treatment plant. The analysis of sewage at the outlet of the dyeing plant allows to predict the creation of promising technology for the conversion of industrial wastewater into a state suitable for reuse in the technological cycle of dyeing fabrics. Having implemented such technology in practice, the problem of minimizing the cost of expensive dyes, reducing the cost of textile products while maintaining its quality, as well as reducing the environmental hazard of waste in the form of wastewater is solved.
