摘要

摘要: 短程反硝化技术将硝酸盐还原的同时实现亚硝酸盐积累，不仅为厌氧氨氧化反应提供底物且能有效利用其反应产生的硝酸盐。因有机碳源需求少、反应速率高、污泥产量低及运行稳定等优点，短程反硝化具有重要的科学和工程意义，成为近年来的研究热点。介绍了短程反硝化技术的发展历程，从影响亚硝酸盐积累的环境因素及微生物群落结构等方面阐述了短程反硝化的原理，同时对现阶段短程反硝化存在的问题以及应用前景进行总结。最后对我国如何实现传统工艺向新兴高效的短程反硝化工艺的实践应用转型提出了建议。

Abstract: The Partial Denitrification (PD) process can not only provide the substrate for the anaerobic ammonium oxidation (ANAMMOX) reaction, but also consume nitrate that is produced by ANAMMOX. Due to the advantages of low demand of organic carbon source, high reaction rate, low sludge yield and stable operation, PD has important scientific and engineering significance and become a research hotspot in recent years. In this review, the development process of PD technology was summarized in detail, together with the principle of PD which was expounded from the aspects of environmental factors on nitrite accumulation and microbial community structure, the existing problems and application prospects of PD. Finally, some suggestions on realizing the transition from traditional process to emerging and efficient PD process in China were put forward.
