Abstract

The integration of wastewater heat recovery (WWHR) and wastewater reuse offers a numerous advantage, making its application possible in various sectors. Nevertheless, this concept faced challenges to the identification of appropriate location. Existing research lacks comprehensive evaluation methods that encompass a various factor for effective decision-making. This study introduces a new evaluation framework that involves different aspects, including thermal energy potential and spatial distribution analysis. The novelty of this research lies in its unique focus on the combination of WWHR and wastewater reuse. Moreover, it introduces a structured evaluation framework that considers multiple criteria and expert opinions, enhancing decision-making precision. Multi-criteria decision analysis (MCDA) was applied to select assessment criteria, which were categorized into three aspects: water-energy supplier, water-energy consumers, and water-energy station. The relative importance of criteria was determined using the analytical hierarchical process (AHP). The results of the AHP highlight significance of factors: treated wastewater flow rate; treated wastewater temperature; water-energy supply distance, and type of water-energy consumer. These factors were assigned weight values of 0.297, 0.186, 0.123, and 0.096, respectively. It is emphasizing their influence in the decision-making process that potential locations depend on the water-energy supplier and water-energy consumer as supply and demand sources.

用于评估废水热回收潜力和废水再利用的新评估框架。
废水热回收(WWHR)与废水回用的结合具有诸多优势,使其在各行各业的应用成为可能。然而,这一概念在确定适当地点方面面临挑战。现有研究缺乏全面的评估方法,无法涵盖有效决策所需的各种因素。本研究引入了一个新的评估框架,涉及热能潜力和空间分布分析等不同方面。这项研究的新颖之处在于它独特地将重点放在了世界水资源和人 力资源与废水回用的结合上。此外,它还引入了一个结构化的评估框架,考虑了多种标准和专家意见,提高了决策的精确性。多标准决策分析(MCDA)被用于选择评估标准,这些标准被分为三个方面:水-能源供应方、水-能源消费者和水-能源站。采用层次分析法(AHP)确定标准的相对重要性。AHP 的结果突出了以下因素的重要性:处理后的废水流量、处理后的废水温度、水能供应距离和水能消费者类型。这些因素的权重值分别为 0.297、0.186、0.123 和 0.096。在决策过程中,潜在地点取决于作为供需来源的水能源供应方和水能源消费方,这就强调了它们的影响。
