1454559（张）日益增长的水需求，伴随着水资源短缺和气候变化可能对水供应产生的影响，给可持续水管理带来了复杂的挑战，表明需要进行综合废水管理，以促进和便利资源回收。本研究旨在通过一个创新的决策框架，集成多学科的方法和工具，并基于上下文的学习，以确定最佳的可持续配置的综合废水管理在给定的情况下。本研究的目标是：（1）创新一个决策框架，即"分散水"，它整合了逆向物流、生命周期分析和经济评估等多个学科的方法和工具;（2）研究人口、地理、气候和城市形态对最佳分散程度的影响;和（3）创建基于环境的学习，以培训未来的从业人员。污水处理水框架将污水系统视为一个反向供应网络，其中节点是处理设施，泵站，而管道接头和连接是管道。该框架通过独特的流程和分布管道模式表示使用紧凑的模型公式。三重底线可持续性指标（具体净现值，碳足迹，富营养化，回收资源的社会价值）制定的目标函数，以优化权衡，并确定最可持续的配置综合污水处理系统。将生成和模拟基于职位的假设情景，以确定影响最佳分散程度的因素。将采用构想-设计-实施-操作的办法，开发一个水资源管理框架的网络应用程序，并利用微博和公用事业伙伴关系作为利益攸关方的交流平台，重新设计两个现有的工程课程。CDIO的学习成果将使用几种评估方法进行评估。过去的研究表明，综合废水管理的一个主要挑战是缺乏一种规划和设计方法来评估和确定特定情况下最可持续的解决方案。该项目解决了这一关键挑战，并将在以下方面推进知识：（1）量化由资源回收驱动的综合废水系统的可持续性;（2）了解影响权力下放程度的因素;以及（3）基于上下文的学习环境对学生精通学科知识，人际交往技能以及产品，流程和系统建设技能的有效性。该项目还将通过逆向物流的视角开发一个新的框架，一个网络工具和一个利益相关者参与的微博交流平台。实现综合废水管理将带来社会效益，在可靠的供水、资源保护、环境恢复以及区域和地方经济发展方面提高社区福祉。该项目将利用阿尔弗雷德·P·斯隆少数族裔博士的支持。计划招募和支持代表性不足的少数民族研究生。研究和教育活动将交织在一起，提供一个基于上下文的学习环境，以培养博士后，研究生和本科生。将通过微型博客、网络工具和公用事业伙伴关系，实现利益攸关方的参与以及研究和教育成果和产品的广泛传播。

1454559 (Zhang). Increasing water demand, accompanied by water scarcity and the likely impact of climate change on water supplies, has created complex challenges for sustainable water management, demonstrating the need for integrated wastewater management that promotes and facilitates resource recovery. This research aims to determine the optimal sustainable configurations for integrated wastewater management under a given context through an innovative decision framework that integrates multi-discipline methods and tools and context-based learning. The objectives of this research are to (1) innovate a decision framework, WasteWATER, that integrates methods and tools from multiple disciplines including reverse logistics, life cycle analysis, and economic valuation; (2) examine the impact of demographics, geography, climate, and urban form on the optimal degree of decentralization; and (3) create context-based learning to train future practitioners.The WasteWATER framework considers wastewater systems as a reverse supply network in which nodes are treatment facilities, pumping stations, and pipe junctions and links are pipelines. The framework uses compact model formulation through unique process and distribution pipeline mode representation. Triple bottom line sustainability indicators (specific net present value, carbon footprint, eutrophication, and social value of recovered resources) are formulated in the objective function to optimize the trade-off and identify the most sustainable configuration of integrated wastewater systems. Placement-based and hypothetical scenarios will be generated and simulated to identify the factors impacting the optimal degree of decentralization. The Conceive-Design-Implement-Operate (CDIO) approach will be used to develop a web application of the WasteWATER framework and redesign two existing engineering courses using microblogging and utility partnerships as a stakeholder communication platform. The CDIO learning outcomes will be evaluated using several assessment methods. Past research has identified that a primary challenge for integrated wastewater management is the lack of a planning and design methodology to evaluate and identify the most sustainable solution under a given context. This project addresses this critical challenge and will advance knowledge in (1) quantifying the sustainability of integrated wastewater systems driven by resource recovery; (2) understanding factors that impact the degree of decentralization; and (3) effectiveness of context-based learning environment for students' proficiency in disciplinary knowledge, interpersonal skills, and product, process, and system building skills. The project also will develop a new framework through the perspective of reverse logistics, a web tool, and a microblogging communication platform for stakeholder participation. Realization of integrated wastewater management will provide societal benefits that enhance community well-being in terms of reliable water supply, resource conservation, environmental restoration, and regional and local economic development. The project will leverage support from the Alfred P. Sloan Minority Ph.D. program to recruit and support under-represented minority graduate students. The research and education activities will be woven together to provide a context-based learning environment to train postdoc, graduate and undergraduate students. Stakeholder participation and wide dissemination of research and education findings and products will be achieved through microblogging, a web tool, and utility partnerships.
