摘　　要：某污水处理厂采用A2/O工艺,扩建、升级改造工程同步实施,采用二级强化处理,深度处理采用V型滤池工艺。升级改造后,污水处理厂实际运行数据表明,CODCr、BOD5、SS、NH3—N、TN和TP的平均去除率分别达到83.4%、93.8%、81.6%、94.3%、51.1%和88.5%,出水各项指标基本能够稳定达到《城镇污水处理厂污染物排放标准》(GB18918—2002)一级A标准。对各污染物指标进行分析,提标改造工程的实施对TN去除的影响相对较小,TN的稳定达标更多地依赖于工艺设计和运行优化。This paper summarized the performance of an upgraded anaerobic-anoxic-oxic（A^2/O）process wastewater treatment plant（WWTP）,in which the expansion and upgrading projects were simultaneously carried out and intensified secondary treatment and V-type filter as tertiary treatment were applied.The poeration data indicated that after upgrading and reconstruction the average CODCr,DOD5,SS,NH3—N,TN and TP removals of the WWTP could reach 83.4%,93.8%,81.6%,94.3%,51.1%,and 88.5,respectively with its effluent quality indices meeting the first grade A of the discharge standard of pollutants for municipal wastewater treatment plant （GB 18918—2002）.Analysis of pollutant indices showed that,little increase in TN removal was observed after the WWTP upgrading,and it seemed that an effective and stable TN removal depended more on A^2/O process design and its optimized operation.
