摘要 离子型稀土矿是我国重要的战略资源,不规范的开采方式,导致了矿区周边大量水体氨氮超标,治理迫在眉睫。由于离子型稀土矿区污水有机质含量少、水质水量变化大,采用传统的污水处理技术进行处理存在处理成本高、运行维护繁琐的问题,而人工湿地脱氮系统能很好的解决上述问题。本文综述了离子型稀土矿区现有的脱氮技术和潜流人工湿地在污水处理方面的研究进展,以期为离子型稀土矿区氨氮污水处理提供新的低成本处理方法。 Ion-type rare earth mine is an important strategic resource in our country.The non-standard mining method leads to the excessive ammonia nitrogen in a large number of water bodies around the mining area,so it is urgent to control.Due to the small content of organic matter in the sewage of ion-type rare earth mining area and the large variation of water quality and quantity,the traditional sewage treatment technology has the problems of high treatment cost and tedious operation and maintenance.The constructed wetland nitrogen removal system can well solve the above problems.In this paper,the existing nitrogen removal technology and the research progress of subsurface flow constructed wetland in wastewater treatment in ion-type rare earth mining area are reviewed in order to provide a new low-cost treatment method for ammonia nitrogen wastewater treatment in ion-type rare earth mining area.
