摘　　要：以新疆某纺织企业染整车间为例,运用水短缺足迹和水劣化足迹理论对浅中深色全棉毛巾染整主要工序的水足迹进行核算和评价,研究水足迹的分布特点。结果表明:后整理工序的水短缺足迹最大,分别占浅中深色毛巾水短缺足迹的36.36%、50.00%、56.25%;前处理工序的水富营养化足迹最大,分别占浅中深色毛巾水富营养化足迹的58.87%、66.59%、61.63%;各工序水酸化足迹都较小,实测工序中硫化物质量浓度均小于0.2 mg/L。Taking the dyeing and finishing workshop of a textile enterprise in Xinjiang province as an ex⁃ample,the water scarcity footprint method and water degradation footprint method are used to calcu⁃late and evaluate the water footprints of the main dyeing and finishing processes of light,medium and dark cotton towels,and the distribution characteristics of the water footprint are studied.The results show that water scarcity footprint of the finishing process is the largest,accounting for 36.36%,50.00%and 56.25%of the water scarcity footprint of light,medium and dark cotton towels respectively.The wa⁃ter eutrophication footprint of the pretreatment process is the largest,accounting for 58.87%,66.59%and 61.63%of the water eutrophication footprint of light,medium and dark cotton towels respectively.The water acidification footprints of the main dyeing and finishing processes are all small,and the mea⁃sured concentration of sulfide is less than 0.2 mg/L.
