Abstract: In the textile industry, printing and dyeing technology, as an essential technical basis, produces a lot of printing and dyeing wastewater (PDW) that jeopardizes the ecological environment and human health. PDW generally has the characteristics of large discharge, high chromaticity, strong toxicity, strong alkalinity, complex componentization, poor biodegradability, large fluctuations in water quality and quality, and high content of organic pollutants, belonging to the type of industrial wastewater that is difficult to manage. In this paper, the current research progress of PDW treatment technology from the aspects of physical technology, chemical technology, and biological technology are reviewed. In addition, measures to reduce the damage caused by printing and dyeing wastewater from three perspectives: treatment principle, processes, advantages, and disadvantages are discussed, which provides a reference point for the treatment of printing and dyeing wastewater. It is worth noting that the article reviews the ABS system, which is gaining attention as an emerging technology under biological technology. The purpose of this paper is to provide a reference basis for the selection and application of technology, and then promote the innovation and development of printing and dyeing wastewater treatment technology.
