Against the background of drastically rising global water demand and increasing pollution and overexploitation of regional water resources, the demand-driven water supply of households and industry is of central importance. Water reuse and desalination are seen as key technologies to overcome potential regional and local water shortage. In the joint projects funded by the German Federal Ministry of Education and Research (BMBF) ‘Future-oriented Technologies and Concepts to Increase Water Availability by Water Reuse and Desalination (WavE)’, evaluation approaches for analysing innovative technologies and concepts are being developed and assessed. All evaluation methods and criteria used were selected based on the decision situation at hand and the decisionmakeŕs preferences. Based on the analysis of six multi-criteria evaluation concepts used in selected WavE projects, this paper presents a general approach for comparative multi-criteria evaluation of water reuse systems consisting of prerequisites, minimum requirements, evaluation criteria (qualitative, semi-quantitative or quantitative) and a final aggregation of results. Exemplary sets of criteria for the application in a more industrial, municipal and/or international context are presented as an aid for the application of holistic evaluation approaches for (process) concept and technology selection in the context of water reuse and desalination.

评估水回用和海水淡化领域面向未来的技术和概念的方法

在全球用水需求急剧增加、区域水资源污染加剧和过度开发的背景下，家庭和工业用水的需求驱动供应至关重要。中水回用和海水淡化被视为克服潜在的区域和地方水资源短缺的关键技术。在由德国联邦教育和研究部 (BMBF) 资助的联合项目“通过水再利用和海水淡化 (WavE) 提高水资源可用性的面向未来的技术和概念”中，正在开发分析创新技术和概念的评估方法并评估。所有使用的评估方法和标准都是根据手头的决策情况和决策者的偏好选择的。基于对选定的 WavE 项目中使用的六个多标准评估概念的分析，本文提出了对水回用系统进行比较多标准评估的一般方法，包括先决条件、最低要求、评估标准（定性、半定量或定量） ) 和最终的结果汇总。在工业、市政和/或国际环境中应用的示例性标准集作为在水回用和海水淡化环境中应用（过程）概念和技术选择的整体评估方法的辅助工具。半定量或定量）和结果的最终汇总。在工业、市政和/或国际环境中应用的示例性标准集作为在水再利用和海水淡化环境中应用（过程）概念和技术选择的整体评估方法的辅助工具。半定量或定量）和结果的最终汇总。在工业、市政和/或国际环境中应用的示例性标准集作为在水再利用和海水淡化环境中应用（过程）概念和技术选择的整体评估方法的辅助工具。
