Abstract

The utilization of waste materials to control phosphorus (P) pollution has been intensively studied as a promising strategy to achieve sustainable wastewater treatment. Although many methods are proposed and investigated to develop modified waste-based adsorbents, a core yet still-debated issue is their effectiveness and viability in real-world applications. Therefore, this critical review summarizes the current research state on the use of waste materials and their modified forms as adsorbents for dissolved reactive P removal from wastewater. Various performance improvement methods are compiled into the research outcomes to highlight three significant efforts that scientists have contributed to promoting the application of waste-based adsorbents: (i) how to enhance the P removal efficiency; (ii) how to scale up implementation; and (iii) how to achieve sustainable management. Furthermore, this review proposes a paradigm of waste-based absorbent in the P removal process to systematically formulate a complete sustainable management strategy for practical application. Overall, this review offers a guide for the development and application of waste-based adsorbents for P removal from wastewater.

摘要

对于控制磷（P）污染的废料的利用已得到深入研究，这是实现可持续废水处理的一种有前途的策略。尽管已提出和研究了许多方法来开发改性的废物基吸附剂，但一个核心但仍存在争议的问题是它们在实际应用中的有效性和可行性。因此，这篇重要的综述总结了关于使用废料及其改性形式作为从废水中去除溶解性反应性P的吸附剂的研究现状。各种性能改进方法被纳入研究成果，以突出科学家为促进废物基吸附剂的应用做出的三项重大努力：（i）如何提高除磷效率；（ii）如何扩大执行力度；（iii）如何实现可持续管理。此外，这篇综述提出了一种在P去除过程中基于废物的吸收剂的范例，以系统地制定出一套完整的可持续管理策略以供实际应用。总的来说，这篇评论为从废水中去除磷的废物基吸附剂的开发和应用提供了指南。
