氧化沟工艺处理城市污水脱氮除磷的影响因素

The influence factors of oxidation ditch treatment of city sewage de-nitrification and phosphorus removal

对烟台某污水厂氧化沟的运行过程中的数据进行了整理分析,得出了该厂生物脱氮的影响因素,找到了确切的脱氮位置,并对进水COD和不同回流比对除磷的影响因素进行了研究,得到了直观的数据,为氧化沟工艺出水氮磷达标提供了参考依据。

This paper made data collection to the operation process of a sewage plant oxidation ditch in Yantai, and analyzed the influence factors of the plant biological de-nitrification, found exact location of nitrogen removal, and researched the influence factors of influent COD and different reflux ratio to phosphorus removal, gained visual data, provided reference basis for effluent nitrogen and phosphorus water achievement of oxida- tion ditch process.
