摘　　要：概括介绍了污水处理厂磷回收所涉及到方法,主要有土地直接利用、化学沉淀、吸附/解吸、强化生物除磷/回收和结晶等。着重分析了典型磷回收工艺,主要包括从污水中回收磷的P-RoC工艺、MBR工艺、REM-NUTR工艺及新型纳米技术,从污泥中回收磷的Aqua Reci工艺、Seaborne工艺、KREPRO工艺和从污泥焚烧灰中回收磷的BioCon工艺、SEPHOS工艺和纳滤工艺等。结合国内外研究现状对我国污水磷回收的前景作了展望。Some methods of phosphorus recovery are firstly summarized which include land utilizing, chemical precipitation, adsorption/disadsorption, enhanced bio-P removal/recovery and crystallization etc. Next, the typical processes of phosphorus recovery are listed such as P-RoC, MBR and REM-NUT processes in wastewater, Aqua Reci, Seaborne and KREPRO processes in sludge, BioCon,SEPHOS and nanofiltration processes in sludge ashes and so on. Finally, the phosphorus recovery future of our country is forecasted combined domestic and foreign research status quo.
