Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] In this example, if figure 1 As shown, 1) Printing and dyeing textile sewage flows into the grid well through the pipelines of each workshop for filtration. After filtration, the dregs that do not pass through the grid well are separated, and the sewage after the separation of dregs is passed into the regulating tank;

[0030] 2) Stir the...

Abstract

The invention provides a textile printing and dyeing waste water treatment process. The process comprises the following steps: introducing waste water into a grating well, recovering sludge separated from an adjusting tank, a floatation tank, an anaerobic hydrolysis tank, a suspended biological filter and a precipitating tank, and draining the waste water through a pipeline; after sludge recovery, introducing the sludge into a concentration tank to obtain supernatant, introducing the supernatant into the adjusting tank, treating once again, and filling muck. The process is simple in method, is low in energy consumption, and is suitable for large-scale treatment of textile printing and dyeing waste water. The visibility of the waste water can be enhanced after treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a printing and dyeing textile sewage treatment process. Background technique [0002] With the development of modern society, the printing and dyeing textile industry also plays an important role in daily life. As the largest printing and dyeing textile country in China, the industrial wastewater discharge of printing and dyeing textile industry has a large amount of water, high content of organic pollutants, complex components, and water quality. The characteristics of large changes will cause great pollution to water bodies. [0003] At present, there are many domestic methods for treating printing and dyeing textile wastewater, including physical adsorption, chemical coagulation, oxidation, electrolysis, and biological enzyme treatment. [0004] However, the current sewage treatment method is single, and the treated sewage often does not meet the environmental discha...
