印染助剂中挥发性有机化合物控制技术及其环境影响评估OA

Volatile organic compounds(VOCs)in dyeing auxiliaries are one of the major air pollution sourc-es in the textile industry.They have complex compositions and distinct emission characteristics,posing signifi-cant threats to the environment and human health.The sources of VOCs in dyeing auxiliaries are reviewed,in-cluding typical organic solvents and functional components in pre-treatment agents,dyeing auxiliaries,and post-treatment agents.The release patterns of VOCs under high-temperature and high-humidity processes are analyzed,the mechanisms and application effects of three control technologies are discussed:source sub-stitution,process optimization,and end-of-pipe treatment.Furthermore,through methods such as life cycle assessment and environmental risk assessment,potential risks during the pollution migration and transforma-tion process are revealed,with the aim of providing scientific basis for the low-carbon control of VOCs in the dyeing industry.
