摘　　要：磷酸盐生物还原除磷作为一种新兴的生物除磷技术,为污水除磷提供了一条新的思路与途径。以磷化氢气体逸出的形式去除污水中的磷,不仅能减少剩余污泥的排放量,还能通过一定的工程措施将磷化氢回收利用,解决磷污染危害与磷资源稀缺的矛盾。在总结磷酸盐生物还原除磷机理研究进展的基础上,分析了影响磷酸盐生物还原除磷的因素,探讨了该技术在实际工程中应用的现状与前景。As a novel biological phosphorus removal technology, phosphate biological reduction provides a new way of thought and pathway for phosphorus removal from sewage. Removing phosphorus from sewage in the form of phosphine gas escape can not only reduce the discharge of excess sludge, but also recycle and utilize phosphine through certain engineering measures so as to solve the contradiction between phosphorus pollution hazard and scarcity of phosphorus resources. Based on the summary of the research progress of the mechanism of phosphate biological reduction removing phosphorus, the factors affecting the phosphorus-removing performance of phosphate biological reduction were analyzed;besides, the application status and prospect of the technology in practical engineering were also discussed.
