摘　　要：离子型稀土矿区流出大量氨氮废水进入周边水体,传统生物处理法存在碳源及氧源需求量大、工艺长、占地面积大等问题。因此,如何高效处理离子型稀土含氮废水是当前研究的难点与热点。膜生物反应器(MBR)短程硝化反硝化技术基于MBR本身优点外,克服了碳、氧源的大量需求、周期长等问题,具有良好的资源化效益,符合长期可持续发展的背景潜能。本文主要从离子型稀土矿区氨氮废水的形成及特性,常用处理技术现状,MBR短程硝化反硝化脱氮性能三个方面进行综述。旨在为MBR短程硝化反硝化工艺处理离子型稀土含氮废水的发展提供理论基础。A considerable amount of ammonia nitrogen wastewater discharges from the ion-type rare earth mining area into the surrounding water bodies.The traditional biological treatment method presents several issues,such as a significant demand for carbon and oxygen sources,lengthy processes,and extensive land occupation.Hence,how to effectively handle the nitrogen-containing wastewater from ion-type rare earth has become a challenging and hot topic in current research.The membrane bioreactor(MBR)short-range nitrification and denitrification technology,in addition to the advantages of MBR itself,overcomes problems like the high demand for carbon and oxygen sources and long cycles.It offers excellent resource benefits and is in line with the background potential of long-term sustainable development.In this paper,the formation and characteristics of nitrogen-containing wastewater in the ion-type rare earth mining area,the current status of common treatment technologies,and the nitrogen removal performance of MBR short-range nitrification and denitrification are reviewed.The aim is to provide a theoretical basis for the development of the MBR short-range nitrification and denitrification process for the treatment of ion-type rare earth nitrogen-containing wastewater.
