Municipal solid waste (MSW) landfill leachate is a highly contaminated liquid effluent. Leachate has a complex nature that needs to be appropriately treated before being discharged into the environment. There are various options for leachate treatment. Deciding which option should be applied is a complex process, since it depends on many factors that need to provide a balance between the technical, economic, and environmental aspects of sustainability. Multi-criteria decision-making (MCDM) methods are useful techniques to solve complex problems that cannot be easily solved. In this study, MCDM techniques are used for an evaluation of four different leachate treatment options: recirculation of leachate to a landfill site (A1), combined treatment with municipal wastewater (A2), anaerobic and aerobic sequential treatment (A3), and advanced leachate treatment based on membrane processes (A4). The selection of the most appropriate one, based on the criteria, analytic network process (ANP), and preference ranking organization method for enrichment evaluations (PROMETHEE) methods, was applied as MCDM techniques using the Super Decisions software and D-Sight software, respectively. Both the ANP and the PROMETHEE analysis results demonstrate that option A2 is the most appropriate for all of the decision-makers.
城市固体废物（MSW）垃圾填埋场渗滤液是一种高度污染的液体废水。渗滤液的性质复杂，在排放到环境中之前需要进行适当的处理。有各种渗滤液处理的选择方案。选择应该应用哪种方案是一个复杂的过程，因为它取决于许多因素，需要在可持续性的技术、经济和环境方面提供平衡。多准则决策（MCDM）方法是解决难以解决的复杂问题的有用技术。在这项研究中，MCDM 技术用于评估四种不同的渗滤液处理选择方案：渗滤液回灌到垃圾填埋场（A1）、与城市废水联合处理（A2）、厌氧和好氧顺序处理（A3）和基于膜过程的高级渗滤液处理（A4）。基于标准、分析网络过程（ANP）和偏好排序组织方法进行富集评估（PROMETHEE）方法的最适合的选择，分别使用 Super Decisions 软件和 D-Sight 软件作为 MCDM 技术进行了应用。ANP 和 PROMETHEE 分析结果均表明，对于所有决策者来说，A2 是最合适的选择。
