氨氮废水处理技术研究进展

针对氨氮废水排放导致的点源污染问题，本文综述了低浓度氨氮废水和高浓度氨氮废水的处理技术在国内外研究进展。低浓度氨氮废水的处理技术包括：生物法，折点加氯法，沉淀法，离子交换法等；高浓度氨氮废水处理技术包括：物化法，生物法，短程硝化反硝化，生物膜一SBR法等。同时，讨论了上述方法在不同浓度氨氮废水中的应用条件与效果，并对今后氨氮废水处理方向做出了展望。对了解和掌握高、低不同浓度氨氮废水污水处理技术具有一定借鉴意义。

Research Progress of Ammonia Nitrogen Wastewater Treatment Technology

Focused on the point source pollution caused by ammonia nitrogen wastewater, this paper reviewed the treatment technologies of ammonia nitrogen wastewater with low and high concentrations. The treatment technologies for low - concentration ammonia nitrogen wastewater included, biological treatment, break point chlorination, precipitation and ion exchange method. Technologies for high concentration wastewater are physicochemical, biological treatment, short - cut nitrification, denitrification and biofilm SBR method. This paper discussed the application conditions and treatment effect, and has proposed the prospects for the future development. It offered a reference to understand and master the treatment technologies of high - and low - concentra- tion ammonia nitrogen wastewater.
