浅谈纪庄子污水处理厂 A 2/O 工艺运行经验 摘要： 随着城市化和工业化程度的不断提高以及化肥和农药的广泛使用， 氮、磷 等营养物质引起的水体富营养化的问题日益突出。 要达到氮磷的排放标准， 许多 污水处理设施需要考虑脱氮除磷问题， 因此选择适宜的脱氮除磷技术在污水处理 中变得日益重要。本文结合天津市纪庄子污水处理厂 A 2/O 工艺系统的运行情况， 对生物除磷脱氮机理、影响除磷脱氮效果的因素进行研究，对 A 2/O 系统的工艺 运行状况进行总结分析，为全面提高 A 2/O 工艺系统运行效果提供可靠的指导经 验。 关键词： 除磷脱氮； A 2/O ；硝化；反硝化 Analysis of A 2/O technology operational experience of Jizhuangzi sewage treatment plant Abstract: With the continuous improvement of urbanization and industrialization, and chemical fertilizers and pesticides widely used, then eutrophication problems of waters have become increasingly prominent, which caused by nitrogen, phosphorus and other nutrients，To achieve the emission standards for nitrogen and phosphorus, many sewage treatment facilities need to consider the removal of nitrogen and phosphorus, so choosing the appropriate dephosphorization and denitrification 2 sewage treatment technology has become increasingly important. With the A/O system operation of Ji Zhuangzi sewage treatment plant in Tianjin, the paper studied the mechanism and effect factors of the biological removal of nitrogen and 2 phosphorus, analyzed the technology operational running situation of the A/O system, and provided reliable guiding experience for comprehensively improving the 2 operational impression of the A/O technology system. 2 Keyword: dephosphorization and denitrification ； A /O ； nitrification ； denitrification 前 言 2 A /O 工艺作为除磷脱氮的主要工艺之一，具有处理效
