ABSTRACT

Among the 17 United Nations Sustainable Development Goals (SDGs), SDG #11 aims to make future cities resilient and sustainable while, SDG #6 aims to ensure availability and sustainable management of water and sanitation for all. In this study, the following five attributes for assessing wastewater infrastructure that can support sustainable cities are distilled from the targets set for SDG #11, #6 and other wastewater-related SDGs: reuse-quality water recovery; safe pathogen reduction; energy use and recovery in wastewater treatment; biofertilizer recovery from wastewater; and emission reduction in wastewater treatment. A total of 36 process parameters are derived to quantify these five attributes. Application of this sustainability-based approach in evaluating an emergent algal-based sewage treatment and resource recovery (STaRR) system against the traditional activated sludge-base sewage treatment practices is presented. This study emphasizes the contribution and the influence of wastewater infrastructures for the sustainability of cities and suggests that the emergent STaRR system is a sustainable pathway to provide wastewater utility service to future cities and to accomplish UN SDGs and targets.

抽象的

在17个联合国可持续发展目标（SDG）中，SDG＃11旨在使未来的城市具有韧性和可持续性，而SDG＃6则旨在确保所有人的水和卫生设施的可用性和可持续管理。在这项研究中，从为可持续发展目标11、6和其他与废水相关的可持续发展目标设定的目标中提炼了以下五个可评估可支持可持续城市发展的废水基础设施的属性：回用质量的水回收；安全减少病原体；废水处理中的能源利用和回收；从废水中回收生物肥料；和减少废水处理中的排放。总共导出了36个过程参数以量化这五个属性。介绍了这种基于可持续性的方法在评估基于新兴藻类的污水处理和资源回收（STaRR）系统方面与传统的基于活性污泥的污水处理方法的对比。这项研究强调了废水基础设施对城市可持续性的贡献和影响，并提出了新兴的STaRR系统是为未来城市提供废水公用事业服务以及实现联合国可持续发展目标和目标的可持续途径。
