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 decision-makers 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.

在全球需水量急剧增加，污染和区域水资源过度开发的背景下，以需求为导向的家庭和工业用水至关重要。中水回用和海水淡化被认为是克服潜在的区域和地方水资源短缺的关键技术。在德国联邦教育与研究部（BMBF）资助的联合项目“面向未来的技术和概念，通过回用水和淡化技术（WavE）增加水的可利用性”中，正在开发用于分析创新技术和概念的评估方法，并且评估。根据手头的决策情况和决策者的偏好选择所有使用的评估方法和标准。在对选定的WavE项目中使用的六个多标准评估概念进行分析的基础上，本文提出了一种用于回用水系统的比较多标准评估的通用方法，包括前提，最低要求，评估标准（定性，半定量或定量） ）和最终结果汇总。提出了在更工业，市政和/或国际环境中应用的示例性标准集，以帮助在水回用和脱盐的背景下对（过程）概念和技术选择的整体评估方法的应用。半定量或定量）和最终结果汇总。提出了在更工业，市政和/或国际环境中应用的示例性标准集，以帮助在水回用和脱盐的背景下对（过程）概念和技术选择的整体评估方法的应用。半定量或定量）和最终结果汇总。提出了在更工业，市政和/或国际环境中应用的示例性标准集，以帮助在水回用和脱盐的背景下对（过程）概念和技术选择的整体评估方法的应用。
