Problems solved by technology

[0002] In daily production and life, water plays an extremely important role as a necessity for human beings. However, with the continuous improvement of living standards and technology, the pollution of water quality in today's society is extremely serious, especially the sewage generated by printing and dyeing factories. , and in many cases, humans do not treat the generated sewage, but directly discharge it into nature, which brings great pollution to nature
[0003] Therefore, the existing printing and dyeing wastewater lacks the use of reagents for effective treatment, which will cause great pollution to nature.
