Abstract

Phosphorus (P) as an essential nutrient for life sustains the productivity of food systems; yet misdirected P often accumulates in wastewater and triggers water eutrophication if not properly treated. Although technologies have been developed to remove P, little attention has been paid to the recovery of P from wastewater. This work provides a comprehensive review of the state-of-the-art P removal technologies in the science of wastewater treatment. Our analyses focus on the mechanisms, removal efficiencies, and recovery potential of four typical water and wastewater treatment processes including precipitation, biological treatment, membrane separation, and adsorption. The design principles, feasibility, operation parameters, and pros & cons of these technologies are analyzed and compared. Perspectives and future research of P removal and recovery are also proposed in the context of paradigm shift to sustainable water treatment technology.

从废水中回收磷：基于当前除磷技术的综述。

磷作为生命的必需营养素，维持着粮食系统的生产力；然而，如果处理不当，被误导的磷经常在废水中积累并引发水体富营养化。尽管已经开发出去除磷的技术，但很少关注从废水中回收磷。这项工作全面回顾了废水处理科学中最先进的磷去除技术。我们的分析重点是四种典型的水和废水处理工艺的机理、去除效率和回收潜力，包括沉淀、生物处理、膜分离和吸附。分析比较了这些技术的设计原理、可行性、运行参数及优缺点。在向可持续水处理技术范式转变的背景下，还提出了磷去除和回收的前景和未来研究。

期刊介绍： Two of the most pressing global challenges of our era involve understanding and addressing the multitude of environmental problems we face. In order to tackle them effectively, it is essential to devise logical strategies and methods for their control. Critical Reviews in Environmental Science and Technology serves as a valuable international platform for the comprehensive assessment of current knowledge across a wide range of environmental science topics. Environmental science is a field that encompasses the intricate and fluid interactions between various scientific disciplines. These include earth and agricultural sciences, chemistry, biology, medicine, and engineering. Furthermore, new disciplines such as environmental toxicology and risk assessment have emerged in response to the increasing complexity of environmental challenges. The purpose of Critical Reviews in Environmental Science and Technology is to provide a space for critical analysis and evaluation of existing knowledge in environmental science. By doing so, it encourages the advancement of our understanding and the development of effective solutions. This journal plays a crucial role in fostering international cooperation and collaboration in addressing the pressing environmental issues of our time.
