鸟粪石结晶沉淀法处理氨氮废水的应用研究

Advances in the Application of Struvite Sediment to Wastewater Treatment

论述了鸟粪石的形成机理、形成的影响因素。在废水处理中采用鸟粪石沉淀法脱氮,具有氨氮去除率高、反应速度快、污泥体积小的优点,同时可以回收氨氮。作为缓释肥,具有良好的经济效益。重点介绍了鸟粪石沉淀法处理氨氮废水目前的研究进展,并探讨了该技术在今后的研究趋势。

This paper discussed the formation mechanism and influencing factors of struvite. Using struvite sediment to remove the nitrogen in waste water has many advantages, such as high removal rate of nitrogen and reaction speed, small amount of sludge, reclaiming the ammonia nitrogen etc. The struvite can be made as the controlled release fertilizer, which has good economic benefit. In this article, the advances in studies on the treatment of ammonia nitrogen wastewater is introduced, and the research trend of this technique is also discussed.
