In the present study, several water recovery and end-of-pipe wastewater treatment alternatives were evaluated towards the evaluation of Best Available Techniques (BATs) for the management of wastewaters from a denim textile mill in accordance with the European Union's Integrated Pollution Prevention and Control (IPPC) Directive. For this purpose, an assessment that translates the key environmental aspects into a quantitative measure of environmental performance and also financial analysis was performed for each of the alternatives. The alternatives considered for water recovery from dyeing wastewaters were nanofiltration (NF) with coagulation and/or microfiltration (MF) pre-treatment, ozonation or peroxone and Fenton oxidation. On the other hand, for the end-of-pipe treatment of the mill's mixed wastewater, ozonation, Fenton oxidation, membrane bioreactor (MBR) and activated sludge (AS) process followed by membrane filtration technologies were evaluated. The results have indicated that membrane filtration process with the least environmental impacts is the BAT for water recovery. On the other side, MBR technology has appeared as the BAT for the end-of-pipe treatment of the mill's mixed wastewater. A technical and financial comparison of these two BAT alternatives revealed that water recovery via membrane filtration from dyeing wastewaters is selected as the BAT for the water and wastewater management in the mill.
在本研究中，根据欧盟综合污染预防和控制 (IPPC) 指令，评估了几种水回收和末端废水处理替代方案，以评估牛仔布纺织厂废水管理的最佳可行技术 (BAT)。为此，对每种替代方案进行了评估，将关键环境方面转化为环境绩效的定量衡量标准，并进行了财务分析。考虑用于从染色废水中回收水的替代方案有纳滤 (NF) 与混凝和/或微滤 (MF) 预处理、臭氧氧化或过氧单硫酸盐和芬顿氧化。另一方面，对于工厂混合废水的末端处理，评估了臭氧氧化、芬顿氧化、膜生物反应器 (MBR) 和活性污泥 (AS) 工艺，然后是膜过滤技术。结果表明，对环境影响最小的膜过滤工艺是水回收的最佳可行技术。另一方面，MBR 技术已成为工厂混合废水末端处理的最佳可行技术。这两种 BAT 替代方案的技术和财务比较表明，从染色废水中通过膜过滤回收水已被选为工厂水和废水管理的最佳可行技术。
