Due to the shortage of phosphorus resources and the limitations of existing phosphorus recovery methods, phosphorus recovery in the form of vivianite has attracted considerable attention with its natural ubiquity, easy accessibility and foreseeable economic value. This review systematically summarizes the chemistry of vivianite, including the characteristics, formation process and influencing factors of the material. Additionally, the potential of phosphorus recovery as vivianite from wastewater has also been comprehensively examined from the prospects of economic value and engineering feasibility. In general, this method is theoretically and practically feasible, and brings some extra benefits in WWTPs. However, the insufficient understanding on vivianite recovery in wastewater/sludge decelerate the development and exploration of such advanced approach. Further researches and cross-field supports would facilitate the improvement of this technique in the future.
由于磷资源短缺和现有磷回收方法的局限性，以蓝铁矿形式进行磷回收因其天然的普遍性、易得性和可预见的经济价值而引起了相当大的关注。本综述系统地总结了蓝铁矿的化学性质，包括该材料的特性、形成过程和影响因素。此外，还从经济价值和工程可行性的角度综合考察了从废水中以蓝铁矿形式回收磷的潜力。总的来说，这种方法在理论和实践上都是可行的，并且在 WWTP 中带来了一些额外的好处。然而，人们对废水中/污泥中蓝铁矿回收的了解不足，这阻碍了这种先进方法的发展和探索。进一步的研究和跨领域支持将有助于提高该技术在未来的应用。
