Abstract：The wastewater generated during the adhesive production process has complex components, high pollutant con-centration, and poor biodegradability. It contains a large number of refractory organic compounds, heavy metal ions, and toxic additives. Random discharge will cause serious damage to the aquatic ecosystem. This paper systematically analyzes the sources and characteristics of wastewater from different types of adhesive production, including core indicators such as pollutant com-position, concentration range, BOD/COD ratio, and toxicity characteristics; focuses on sorting out the mechanism of action, application effects and applicable scenarios of physical and chemical treatment technologies, biological treatment technologies and combined processes. The research shows that in view of the complexity of adhesive production wastewater, it is necessary to customize a comprehensive treatment plan of "source emission reduction, process control, end-of-pipe treatment, and resource utilization" according to the characteristics of the wastewater. Among them, the advanced oxidation-biological combined tech-nology can efficiently degrade refractory organic compounds, and the effluent quality is stably up to the standard, providing the-oretical support and practical reference for the wastewater treatment of adhesive enterprises.
