Abstract

Struvite precipitation is an efficient approach to recover phosphorus and ammonium from wastewater to alleviate many operational as well as environmental issues. The sparingly soluble nature of struvite in water makes it a potential slow‐release fertilizer whose adequacy has been investigated in various soil‐based cultivation. However, struvite has diverse applications other than field usage which are yet to be explored. The review highlights the usage of struvite as a fertilizer in soil along with its other applications as a nutrient supplier in hydroponic systems, fire retardants, and sorbent for the adsorption of heavy metals, dye, and gases. The research gaps between the lab and the application of the struvite products in the market for its proper utilization have also been reported. Thus, struvite produced from wastewater can be a promising green chemistry that could replace many costly, synthetic, and harmful products, while conserving phosphorous resource at the same time.This article is categorized under:

循环经济中的铁石棉：生产技术、新兴应用和市场机遇

从废水中回收磷和铵是一种有效的方法，可以缓解许多操作和环境问题。稀土在水中的微溶性使其成为一种潜在的缓释肥料，在各种土壤栽培中的充分性已得到研究。不过，除了田间使用外，硬石膏还有其他多种用途，有待探索。本综述重点介绍了硬石膏在土壤中作为肥料的用途，以及在水培系统中作为营养供应剂、阻燃剂和吸附重金属、染料和气体的吸附剂的其他应用。此外，还有报告指出了实验室与市场应用之间的差距。因此，从废水中生产的硬石膏可以成为一种前景广阔的绿色化学产品，它可以替代许多昂贵、合成和有害的产品，同时还能保护磷资源：气候与环境 > 循环经济新兴技术 > 材料可持续发展 > 目标

期刊介绍： Wiley Interdisciplinary Reviews: Energy and Environmentis a new type of review journal covering all aspects of energy technology, security and environmental impact. Energy is one of the most critical resources for the welfare and prosperity of society. It also causes adverse environmental and societal effects, notably climate change which is the severest global problem in the modern age. Finding satisfactory solutions to the challenges ahead will need a linking of energy technology innovations, security, energy poverty, and environmental and climate impacts. The broad scope of energy issues demands collaboration between different disciplines of science and technology, and strong interaction between engineering, physical and life scientists, economists, sociologists and policy-makers.
