Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to high-efficiency sewage decolorization treatment equipment for printing and dyeing textiles. Background Art

[0002] Printing and dyeing textile wastewater is a difficult-to-treat industrial wastewater with the characteristics of high organic matter concentration, complex composition, deep and variable chromaticity, large pH changes, and large changes in water quantity and quality. In order to effectively treat this wastewater, a variety of methods can be used, including chemical treatment, physical treatment and biological treatment. The chemical treatment method mainly includes coagulation and oxidation. The coagulation method uses coagulants to condense suspended particles and colloidal substances in the wastewater into large particles and settle, thereby achieving the purpose of separation; the oxidation method uses strong oxidants to oxidize and decompose organic matter in the wastewater into small molecules, such as ozone oxidation. Physical treatment methods mainly include filtration, sedimentation, flotation and other methods, which can remove suspended matter and chromaticity in wastewater. The biological treatment method uses the metabolism of microorganisms to convert organic matter in wastewater into harmless substances, such as activated sludge method.

[0003] The high-efficiency decolorization treatment equipment for printing and dyeing textile supporting wastewater is used to treat wastewater containing dyes and pigments generated by the printing and dyeing textile industry. Since the dyes and pigments used in the printing and dyeing process will make the wastewater present a high concentration of color, traditional sewage treatment methods cannot effectively remove the color, so special decolorization equipment is required.

[0004] After retrieval, announcement number CN115367849B, announcement date 2023-05-02 discloses an efficient treatment equipment for decolorization of printing and dyeing textile supporting wastewater, including a sewage treatment tank, a chemical barrel, a premixing mechanism, a partition support plate assembly, a stirring mechanism and a sludge extraction mechanism. The chemical barrel is connected to the bottom of the sewage treatment tank through a conduit, and a premixing mechanism for preliminarily mixing sewage and chemicals is installed at the bottom center of the sewage treatment tank. The stirring mechanism uses multiple stirring rods to fully stir the mixed sewage upflowing from the bottom of the sewage treatment tank, so that the printing and dyeing sewage is fully decolorized. In this way, after the preliminary mixing and stirring of the premixing mechanism and the secondary stirring of the stirring rod, the decolorizer and flocculant can react quickly and fully with the printing and dyeing sewage. At the same time, the vortex generated during the stirring process is used to aggregate flocculants to promote their aggregation and precipitation, which makes up for the defect of slow aggregation and precipitation due to stirring in conventional treatment equipment.

[0005] The patent has the following shortcomings: 1. The internal parts of the treatment equipment are not easy to clean. After the printing and dyeing textile wastewater is treated, the dirt adhering to the parts is difficult to remove in time, which affects the subsequent wastewater treatment effect; 2. The treatment efficiency of the treatment equipment is not ideal. It takes a lot of time to flocculate and decolorize the wastewater, making it difficult to efficiently and quickly treat a large amount of printing and dyeing textile wastewater.
