Nowadays, sewage treatment has been widely used in many fields such as environmental protection, urban landscape, medical treatment, and the printing and dyeing industry is also one of them. With the continuous development of the textile industry, the discharge of dye wastewater has also increased sharply. At present, the wastewater discharged from China's textile industry mainly comes from the printing and dyeing industry, and printing and dyeing wastewater is one of the difficulties in industrial wastewater treatment. These wastewater mainly come from processes such as bleaching, dyeing, desizing, and finishing. In addition to containing a large amount of pulp and additives, they also contain various toxic pollutants. In addition, printing and dyeing wastewater has characteristics such as large water volume, high organic pollutant content, deep color, high alkalinity, and significant water quality changes, which increase the difficulty of its treatment.

How to treat printing and dyeing wastewater with low consumption and high efficiency has always been a topic of continuous exploration and research in the industry. In this article, we will use a water treatment development limited company as an example to explain how to achieve low consumption, high efficiency, stability, and cost-effectiveness in wastewater treatment through customized solutions. Starting from the application needs, a high standard technical solution is customized. The project adopts advanced sewage treatment equipment, and the main process of the factory adopts A/O treatment process, which greatly improves the urban water environment and plays an important role in pollution control, protecting the water quality and ecological balance of the local watershed.
