Abstract

This study examines the sources, hazards, occurrence forms, and removal mechanisms of nitrogen (N) and phosphorus (P) in polluted waters. Furthermore, it critically reviews various studies on adsorbents for removing N/P-containing pollutants from wastewater, such as activated carbon and mineral-based adsorbents. These adsorbents employ various adsorption mechanisms, such as electrostatic attraction and chemisorption. These adsorbents demonstrate efficacy in simultaneously removing nitrate and phosphate from aqueous solutions. Mineral-based adsorbents exhibit high adsorption capacity for N and P pollutants, potentially enabling a "waste for waste" approach. However, developing cost-effective adsorbents is crucial for long-term environmental and economic sustainability. This review offers a novel systematic analysis of adsorbents for N and P removal via co-adsorption. Moreover, this study explores future research directions in advanced purification technologies, adsorbent regeneration, and recycling of spent adsorbents.

污水处理中同步脱氮除磷吸附剂的研究进展

本研究探讨了受污染水体中氮（N）和磷（P）的来源、危害、出现形式和去除机制。此外，本研究还对用于去除废水中含 N/P 污染物的吸附剂（如活性炭和矿物基吸附剂）的各种研究进行了认真评述。这些吸附剂采用了各种吸附机制，如静电吸引和化学吸附。这些吸附剂在同时去除水溶液中的硝酸盐和磷酸盐方面效果显著。矿物基吸附剂对氮和磷污染物具有很强的吸附能力，有可能实现 "变废为宝"。然而，开发具有成本效益的吸附剂对于环境和经济的长期可持续发展至关重要。本综述对通过共吸附去除氮和磷的吸附剂进行了新颖的系统分析。此外，本研究还探讨了先进净化技术、吸附剂再生和废吸附剂回收利用方面的未来研究方向。
