| 摘 要： | A2/O工艺是一种最简单的同步脱氮除磷工艺,但由于其系统中固有的基质竞争和污泥龄等矛盾,在实际应用中特别是处理低C/N比污水时脱氮除磷效率较低.反硝化除磷工艺作为近年来颇受关注的污水生物处理新技术.由于在脱氮除磷过程中可以在碳源利用上耦合,可从一定程度上缓解A2/O工艺中的基质竞争矛盾,使得其在处理低C/N比污水时也能实现较高的脱氮除磷效率.就反硝化除磷的技术原理,结合其在A2/O工艺中的最新研究成果及其控制策略,对A2/O工艺中的反硝化除磷的实现、维持及影响因素进行了分析和探讨,并对其发展方向进行了展望.

| Abstract: | Anaerobic-anoxic-oxic (A2/O) process is a simple wastewater treatment process that can achieve both nitrogen and phosphorus removal. However, some inherent contradictions, for example, substances competition and SRT problems, make it very difficult to raise the nutrients removal efficiency when treating low C/N ratio wastewater. As a new developed technology, denitrifying phosphorus removal can solve those contradictions to a certain extent, even treating low C/N ratio wastewater. The aims of this work are to exhibit the technique principle of denitrifying phosphorus removal and the latest research in A2/O process with denitrifying phosphorus removal. Some operational strategies are also included to give a total presentation of A2/O process with denitrifying phosphorus removal. The main developmental trends of denitrifying phosphorus removal in A2/O are also discussed here. |
