摘　　要：随着节能低碳理念的深入发展,鸟粪石沉淀法因其较高的氮磷回收效率和相对低能耗的优势,近年来成为高浓度氮磷废水处理和资源化利用的热点方向之一。系统地对国内外鸟粪石沉淀法处理污水的相关文献进行了梳理,从新兴处理对象及方案、回收反应器构型开发、低成本镁源开发、高效结晶、晶体分离提纯等方面,总结了相关研究成果。此外,结合环境毒理性、处理成本、综合资源化利用等角度对鸟粪石沉淀法的发展前景和趋势进行预判,为相关研究提供参考。With the in-depth development of the concept of energy conservation and low carbon,struvite precipitation method has become one of the hot directions of high concentration nitrogen and phosphorus wastewater treatment and resource utilization in recent years because of its high nitrogen and phosphorus recovery efficiency and relatively low energy consumption.In this paper,the relevant literatures on the treatment of wastewater by struvite precipitation method at home and abroad in recent years were systematically reviewed.The recent research results were summarized in terms of emerging treatment objects and schemes,development of recovery reactor configuration,development of low-cost magnesium source,efficient crystallization,crystal separation and purification,etc.In addition,the future development prospect and trend of struvite precipitation method were predicted from the perspectives of environmental toxicology,treatment cost and comprehensive resource utilization,which provided reference for relevant research.
