摘要
磷矿数量减少与含磷污水造成的水体富营养化问题对磷资源的可持续利用提出了迫切要求。从污水处理的不同环节回收磷并重新利用,是实现磷资源循环利用的有效途径。本文讨论了国内外磷回收技术的研究进展和应用实例,包括从含磷污泥和富磷污水中回收磷的工艺,并对磷回收的技术经济性进行了分析。
Declining of phosphorus resources and waterboby eutrophication caused by wastewater both require the sustainable utilization of phosphorus. Phosphorus recovery from the process of wastewater treatment is an effective way for phosphorus reusing and reeycling. In this article, the latest progresses of phosphorus recovery from sludge and phosphorus-rich supernatant are discussed. Furthermore, the technical and economic potentials of phosphorus recovery are analyzed.
