Enterprise printing and dyeing wastewater treatment

The printing and dyeing industry is a typical high water consuming industry that consumes nearly 100 million tons of process softened water annually. The sources and pollutant components of printing and dyeing wastewater are very complex, with characteristics such as large changes in water quality, high organic content, and high chromaticity (mainly colored dyes). Direct discharge poses great harm to human health and the living environment, while also causing waste of water resources. With the increasing attention of the country and society to environmental protection requirements and the demand for sustainable development, traditional treatment methods have become increasingly difficult to meet the requirements of production and environmental protection.
