纺织印染废弃物环境设计与资源化利用OA

The textile printing and dyeing industry is a typical high-pollution sector,where waste environ-mental risks coexist with the potential for resource utilization.The composition characteristics and environmen-tal hazards of printing and dyeing waste were systematically explained,the bottlenecks of traditional treatment technologies in the deep removal of pollutants and resource recovery were focused on,and the core techno-logical progress of resource utilization paths such as wastewater closed-loop circulation,salt separation and regeneration,efficient dye recovery,and solid waste pyrolysis energy conversion and material reconstruction were analyzed.Based on the perspective of the life cycle,it proposes a"source-process-end"full-chain en-vironmental design strategy covering green chemical substitution,optimization of clean production processes,and multi-industry collaboration.Through cross-innovation in chemical engineering,environmental science,and industrial ecology,a systematic transformation from reducing pollution load to converting waste into re-source value can be achieved for printing and dyeing waste.
