The quality of dyeing and printing wastewater is complex,and the changes in various substances in the wastewater are fast,making it a difficult-to-biologically-treat and-degradable wastewater.By choosing a reasonable process and upgrading and improving the existing wastewater treatment plant,the biodegradability of the wastewater can be improved,thereby raising the water quality standard.This paper com-bines the pollution characteristics of dyeing and printing wastewater in a certain industrial park and discusses the upgrading and improvement technology of dyeing and printing wastewater treatment.It can provide reference for related engineering projects to achieve water discharge standards and environmental protection.
