Wastewater treatment consumes large amounts of energy and materials to comply with discharge standards. At the same time, wastewater contains resources, which can be recovered for secondary uses if treated properly. Hence, the goal of this paper is to review the available resource recovery methods onsite or offsite of municipal wastewater treatment plants. These methods are categorized into three major resource recovery approaches: onsite energy generation, nutrient recycling and water reuse. Under each approach, the review provides the advantages and disadvantages, recovery potentials and current application status of each method, as well as the synthesized results of the life cycle studies for each approach. From a comprehensive literature review, it was found that, in addition to technology improvements, there is also a need to evaluate the applications of the resource recovery methods in wastewater treatment plants from a life cycle perspective. Future research should investigate the integration of the resource recovery methods to explore the combined benefits and potential tradeoffs of these methods under different scales.
污水处理需要消耗大量的能源和材料来达到排放标准。同时，污水中含有资源，如果处理得当，可以回收再利用。因此，本文的目的是回顾市政污水处理厂现场或场外的现有资源回收方法。这些方法分为三种主要的资源回收方法：现场能源生产、营养物回收和水再利用。在每种方法下，审查提供了每种方法的优缺点、回收潜力和当前应用状态，以及每种方法的生命周期研究的综合结果。从全面的文献回顾中发现，除了技术改进外，还需要从生命周期的角度评估资源回收方法在污水处理厂中的应用。未来的研究应探讨资源回收方法的整合，以探索这些方法在不同规模下的综合效益和潜在权衡。
