The textile dyeing industry produced large volumes of wastewater every year and wastewater contains many
toxic pollutants. These pollutants are difficult to deal with. Therefore, effective treatment methods and technology to dye
wastewater are an important guarantee of eliminating bottlenecks in printing and dyeing industry, improving the ecological
environment and safeguarding human health. In this article, the relevant developments reported recently in the open
literatures, especially in the patents, were focused on the advances on treatment of dying wastewater. Furthermore, suggestions
for future research are also put forward.
Keywords: Dye wastewater, dyestuff, toxic pollutants, treatment technology, human health, prospects.
