Corporate Water Footprint of Textile Industry:Methodology and Case Study

  • 摘要: 企业水足迹可用于节水减排效果的评价. 企业蓝水足迹指企业对传统水源的消耗,绿水足迹指企业收集处理并用于生产等目的的降水量;灰水足迹指以自然本底浓度和环境水质标准为基准,将企业产生的污染物负荷吸收同化所需的淡水量. 概化了企业用、排水模型,并基于《水足迹评价手册》建立了企业水足迹测算方法,测算了企业蓝水足迹、绿水足迹和灰水足迹,以及节水减排措施对削减水足迹的贡献率. 根据该测算方法对某纺织印染企业开展了案例研究. 结果表明:①经过清洁生产审核,某纺织印染企业的单位产品产量蓝水足迹为171 t/t,削减了26.3%;单位产品产量灰水足迹为146 t/t,削减了31.1%;而由于降水的采用,单位产品产量绿水足迹由0 t/t增至8 t/t;②在节水减排贡献方面,水回用措施显著大于工艺节水措施,节水和水回用措施分别削减蓝水足迹1.77×104和48.60×104 t,二者分别削减灰水足迹1.60×104和57.80×104 t.
