摘　　要：氮是城市污水中的主要营养物,如果不经处理任意排放会引起受纳水体的富营养化。目前对城市污水的处理多采用A/O工艺及其变形工艺,但是一般A/O工艺存在内回流比高、水力停留时间长、容积利用率低等问题,使得运行费用过高。把H/O脱氮工艺与A/O脱氮工艺进行对比研究,考察H/O脱氮工艺与A/O脱氮工艺在对污水的适用性、处理能力、运行的稳定性等方面的差别,以及探讨和优化反应器各部分在脱氮除磷过程中的作用、功能及主要的运行机理。Nitrogen is the main tropHic substance in municipal wastewater. It results in entropHication question with discharging wastewater casually and untreated. A/O process and its transformation processes are the predominant processes now. But it costs too much in A/O process because of high RSF,long HRT and low using in space, a contrast study between H/O and A/O processes was carried out in flexibility, capability and stability in treating wastewater, the function and mechanism of each part in process during denitrifying pHospHorus removal were discussed and optimized.
