纺织业对环境的影响不断加快,特别是在水管理方面,需要有效的废水处理策略。这项研究检查了电凝聚(EC)过程中各种电极对处理纺织废水的有效性,专注于去除总悬浮固体(TSS),浊度,化学需氧量(COD),和总有机碳(TOC)。使用36个电极对组合进行了综合分析,由六种材料组成:铝(Al),锌(Zn),碳(C),铜(Cu),低碳钢(MS),不锈钢(SS)。结果表明,不同的电极对对各种污染物产生不同的去除效率,COD(Al-C对)的最高效率为92.09%,TSS(Al-Cu对)为99.66%,浊度为99.17%(Al-MS对),TOC(SS-SS对)为70.99%。然而,没有单个电极对在去除所有污染物类别方面表现出色。为了解决这个问题,三种多准则决策(MCDM)方法,如TOPSIS,VIKOR,和PROMETHEEII用于评估最有效的电极对。结果表明,Al-Zn组合是最有效的,对各种污染物表现出高去除效率(TSS为99.32%,浊度为98.88%,COD为68.62%,TOC为57.96%)。这项研究表明,EC工艺可以有效地处理纺织废水,并强调选择合适的电极材料的重要性。此外,在Al-Zn电极对的情况下,污染物去除效果最佳,为纺织废水处理提供了一种平衡有效的方法。因此,MCDM方法为评估和优化电极选择提供了一个强大的框架,为可持续环境管理实践提供有价值的见解。
The accelerating environmental impact of the textile industry, especially in water management, requires efficient wastewater treatment strategies. This
study examines the effectiveness of various electrode pairs in the Electrocoagulation (EC) process for treating textile wastewater, focusing on removing of Total Suspended Solids (TSS), turbidity, Chemical Oxygen Demand (COD), and Total Organic Carbon (TOC). A comprehensive analysis was conducted using thirty-six electrode pair combinations, consisting of six materials: Aluminium (Al), Zinc (Zn), Carbon (C), Copper (Cu), Mild Steel (MS), and Stainless Steel (SS). The results demonstrated that different electrode pairs yielded varying removal efficiencies for various pollutants, with the highest efficiencies being 92.09% for COD (Al-C pair), 99.66% for TSS (Al-Cu pair), 99.17% for turbidity (Al-MS pair), and 70.99% for TOC (SS-SS pair). However, no single electrode pair excelled in removing all pollutant categories. To address this, three Multi-Criteria Decision Making (MCDM) methods such as TOPSIS, VIKOR, and PROMETHEE II were used to assess the most effective electrode pair. The results indicated that the Al-Zn combination was the most efficient, exhibiting high removal efficiencies for various pollutants (99.32% for TSS, 98.88% for turbidity, 68.62% for COD, and 57.96% for TOC). This
study demonstrates that the EC process can effectively treat textile effluent and emphasizes the importance of selecting suitable electrode materials. Furthermore, pollutant removal was optimal with the Al-Zn electrode pair, offering a balanced and efficient approach to textile wastewater treatment. Thus, MCDM methods offer a robust framework for assessing and optimizing electrode selection, providing valuable insights for sustainable environmental management practices.
