[0026] 1. In the present invention, by setting a homogenizing regulating tank, various types of sewage generated in the process of fabric printing and dyeing can be first transported to the homogenizing regulating tank, and various types of wastewater are mixed and stirred by the homogenizing regulating mechanism for homogenizing and regulating before being transported to the subsequent multi-stage purification mechanism for purification, so that the types and contents of pollutants in the sewage entering the multi-stage purification mechanism are maintained within a certain range, so that there is no need to adjust the sewage treatment process according to the types and contents of pollutants in the sewage, which can reduce the difficulty of sewage treatment and improve the sewage treatment effect.

[0027] 2.
