摘要:
风化壳淋积型稀土矿以铵盐为浸取剂的原地浸出过程会产生大量氨氮废水,进行脱氮处理方法有物化脱氮法和生物脱氮法。本文综述了氨氮废水不同脱氮方法。物化法适合预处理高浓度稀土矿山氨氮废水;生物脱氮法成本低、处理规模大、脱氮效率高且环境友好,适合处理低浓度氨氮废水。重点论述了厌氧氨氧化和异养硝化-好氧反硝化等新型生物脱氮法的脱氮机理、影响因素及其应用,为稀土矿山氨氮废水脱氮处理提供了一定的理论基础。相较于传统生物脱氮法,厌氧氨氧化和异养硝化-好氧反硝化更适合处理稀土矿山氨氮废水。通过利用现代分子生物学技术,深入研究厌氧氨氧化脱氮法稳定运行策略及异养硝化-好氧反硝化脱氮法脱氮工艺,有望实现稀土矿山氨氮废水低成本、高效脱氮。
Abstract:
A large amount of ammonia nitrogen wastewater is produced through the in situ leaching of the weathered crust elution-deposited rare earth ore using ammonium salt as the leaching agent, which can be treated with physical-chemical or biological methods for denitrification. This paper summarizes the different denitrification methods of ammonia nitrogen wastewater. Physical-chemical method is suitable for pretreatment of high concentration rare earth mine ammonia nitrogen wastewater. Biological denitrification method is suitable for treatment of low concentration ammonia nitrogen wastewater due to its low cost, large treatment scale, high denitrification efficiency and environmental friendliness. This review focuses on the denitrification mechanisms, influencing factors and the applications of new biological denitrification methods such as anaerobic ammonia oxidation and heterotrophic nitrification-aerobic denitrification, which provides a certain theoretical basis for the denitrification treatment of ammonia nitrogen wastewater from rare earth mines. Compared with traditional biological denitrification methods, anaerobic ammonia oxidation and heterotrophic nitrification-aerobic denitrification are more suitable for treating ammonia nitrogen wastewater from rare earth mines. By using modern molecular biology techniques and intensive research on the stable operation strategy of anaerobic ammonia oxidation denitrification and the denitrification process of heterotrophic nitrification-aerobic denitrification, these new biological denitrification methods are expected to achieve low-cost and high-efficiency denitrification of ammonia nitrogen wastewater from rare earth mines.
