摘要
纺织印染行业是废水及污染物排放量最大的工业行业之一,同时也是能源密集及碳排放高的行业;废水低碳治理已成为纺织印染行业可持续发展的重要路径。在分析印染废水处理工艺温室气体排放特征的基础上,提出依据染化料助剂推定的碳排放潜势概念;针对纺织印染废水处理工艺复杂及水质时变性大的问题,建立了基于碳氮物料平衡的废水处理工艺碳排放精准核算方法。面向废水低碳处理运行需求,总结了纺织印染废水低碳治理技术进展及发展方向。
Textile printing and dyeing industry is one of the industrial industries with the largest discharge of waste⁃water and pollutants.It is also featured by energy-intensive and high-carbon emission characteristics.Low-carbon wastewater treatment has become an important path for sustainable development.Based on the analysis of the green⁃house gas emission characteristics of printing and dyeing wastewater treatment process,the concept of carbon emis⁃sion potential in terms of used dyes was proposed.To address the complexity and variability of wastewater treatment process and wastewater quality,an accurate estimation method of carbon emission in wastewater treatment process was established according to carbon and nitrogen mass balance.The progress and development direction of lowcarbon treatment technology for textile printing and dyeing wastewater were summarized in this paper.
