Problems solved by technology
[0002] The textile printing and dyeing industry mostly uses water to add pigments to dye fabrics. The textile printing and dyeing wastewater produced has the characteristics of large water volume, high content of organic pollutants, deep color, high alkalinity, and large changes in water quality. Usually, printing and dyeing wastewater uses biochemical method, but the treatment effect is often unsatisfactory in the actual operation process. The main reason is that the composition of the discharged wastewater changes greatly due to the change of the type of dyeing, and the water volume of the wastewater also changes greatly, and some production processes The additives used in the process are not conducive to the growth of biological reaction bacteria. Because the printing and dyeing wastewater treatment technology is too simple, the wastewater treatment effect is poor
