| 摘 要： | A-A2/O工艺是预缺氧/厌氧/缺氧/好氧组成的生物脱氮除磷工艺，广州市某污水处理厂采用该工艺处理城市污水，具有同时去除有机物、脱氮除磷能力，但是TN去除率较低。分析了其TN去除率低的原因，并提出相应措施。该水厂针对本厂水质特征以及影响工艺脱氮性能的主要因素，优化了工艺控制参数，提高了TN去除率和TN达标保证率。

| Abstract: | The A-A2/O process is composed of pre-anoxic/anaerobic/anoxic/oxic biological process for removal of nutrient and phosphorus.In Guangzhou,there is an A-A2/O wastewater treatment plant,with simultaneous removal of organic matter,nutrient and phosphorus,but the TN removal rate was low.The reasons for the low TN removal rate were found out,and appropriate measures were proposed.According to the variation of water quality and the main factors affecting the nitrogen removal performance in the treatment plant,controlling parameters were also optimized to improve the TN removal efficiencies. |

| Keywords: | A-A2/O process operation efficiency nitrogen removal performance operationparameters optimization |
