摘要
氨氮浓度高是垃圾渗滤液的水质特征之一,目前对于高浓度氨氮废水的处理方法主要有硝化—反硝化、氨吹脱法、化学沉淀法以及新型生物脱氮技术。基于工程实例,对国内外已有的去除垃圾渗滤液高浓度氨氮的方法进行了阐述和对比,并对渗滤液处理厂脱氮方式的选择提出了建议。
Refuse disposal leachte is highly concentrated with ammonia content. The main methods to treat this liquid include nitrification/denitrification, air stripping, chemical precipitation and new developed biological nitrogen removal methods. In this paper, the methods to treat high concentrated ammonia leachate have been elaborated and compared. This paper also gives the suggestion how to choose nitrogen removal methods in leachate treatment plant.
