    Textile printing and dyeing wastewater reuse treatment equipment

    Overview:
    The textile printing and dyeing industry is a large industrial sewage discharger. The sewage mainly contains dirt, grease, salts on textile fibers, and various pulps, dyes, surfactants, auxiliaries, acids and alkalis added during processing. The wastewater is characterized by high concentration of organic matter, complex composition, deep and variable color, large change in pH, large change in water quantity and water quality, and it is difficult to treat industrial wastewater. With the development of chemical fiber fabrics, the rise of artificial silks and the increase in printing and dyeing finishing requirements have made PVA pulp, rayon alkali hydrolysates, new dyes, auxiliaries and other difficult-to-degrade organic matter enter a large number of textile printing and dyeing wastewater. The treatment process poses a serious challenge, and the COD concentration also rises from several hundred milligrams per liter to 3000 to 5000 mg / l. If it is discharged directly, the pollution to the water body is very serious.
    As we all know, the printing and dyeing industry is a large user of water and a large user of sewage. Printing and dyeing enterprises generally have a complete sewage treatment system. After the sewage treatment, the effluent reaches the first or second level of discharge standards. However, due to the increasing shortage of water resources and serious pollution, regardless of the cost of the enterprise or the development requirements of social environmental protection, printing and dyeing wastewater Reuse after further processing is necessary. Based on many years of experience in the industry and the unremitting efforts of designers and engineers, our company has designed a complete set of printing and dyeing wastewater reuse technology in terms of printing and dyeing wastewater reuse technology, which can make the recycled water quality reach the factory water standard, save energy and reduce emissions, and recycle economy. , Efficient and environmentally friendly, providing the best service for enterprises to solve sewage and reduce production costs.
