Abstract: Although the treatment technologies for high-concentration ammonia nitrogen wastewater in industry are comparatively mature,there have not been effective solutions to the problems in the advanced treatment of low-concentration ammonia nitrogen wastewater yet. Based on that,it introduces emphatically the methods that are widely used for treating low-concentration ammonia nitrogen wastewater,such as the break point chlorination,adsorption, membrane separation,oxidation technology,ultrasound and chemical precipitation,etc. Application status and limiting factors of these methods for removing ammonia nitrogen are summarized via examples. At the end,some suggestions on the future developing direction for the treatment of low-concentration ammonia nitrogen wastewater are proposed.

Key words: industrial wastewater, low-concentration ammonia nitrogen wastewater, advanced treatment

摘要: 工业上对高浓度氨氮废水的处理技术已较为成熟,但涉及低浓度氨氮废水的深度处理尚无十分有效的解决方案。基于此,着重介绍了目前处理低浓度氨氮废水的研究方法,包括折点氯化法、吸附法、膜分离法、氧化法、超声法和化学沉淀法等,通过实例指出这些方法在氨氮去除领域的应用现状与限制因素。最后,对低浓度氨氮废水处理的未来发展方向提出建议。
