摘要
基于反硝化除磷理论开发的A2N双污泥工艺已经成为国内外污水生物处理领域的研究重点,介绍了A2N双污泥反硝化除磷工艺的原理及其发展,深入分析了该工艺的固有弊端,综述了国内外学者针对A2N工艺的弊端所提出的对策和改进工艺,并对其进行评价,指出了当前研究中存在的主要问题,提出了今后的研究方向。
The A2N two-sludge process developed based on the theory of denitrifying dephosphatation has become a research hotspot in the field of wastewater biological treatment all over the world.The denitrifying dephosphatation mechanism of A2N two-sludge process and its development were introduced briefly;and then,the inherent shortcomings of the said process were analyzed.In view of the existing shortcomings,the countermeasures and the improved process have been pointed out by scholars both in China and abroad.Based on the summarization and analysis of the research status,the main problems of the current research were revealed and the future research direction was put forward.
