中文摘要：

污水中含有大量的磷,经过处理回收可以转变为磷资源,又可以保护水环境.对除磷技术和回收磷作了阐述.所涉及的除磷方法中,有化学除磷、生物除磷（强化生物除磷）及生态除磷,也可将各种方法联合使用,人工湿地是一种人工强化的废水生态过程处理技术.MgNH4PO4·6H2O被认为是最有前景的磷回收途径之一,而我国在这方面的研究还处于起始阶段,需要进一步开发研究.

英文摘要：

There is large quantity of phosphorus in wastewater, which can be transformed into resource by recovery and can be helpful to water environment protection. Both phosphorus removal and recovery techniques are presented in this paper. Methods of phosphorus removal, which include chemical processs, biological processs（enhanced biological phosphorus removal, EBPR） and ecological process, can be combined. Such as constructed wetland is an ecological treatment technology, which is strengthened by man. Struvite is regarded as one of the most promising means of the phosphorus recovery. While, in China, the study of this area is still at the beginning stage and further research need to be done.
