五箱一体化活性污泥法除磷脱氮性能初步研究

Study on N and P removal characteristics of integrated activated sludge system with five tanks

五箱一体化活性污泥工艺是东南大学正在研究开发的智能化中小型污水除磷脱氮新工艺,它具有脱氮除磷效率高、占地面积小、自动化程度高、操作简便等优点。简要阐述了五箱一体化活性污泥工艺的基本组成、运行过程与技术特点,并将该工艺应用于某医院污水处理工程,在工程调试过程中取得了五箱一体化活性污泥工艺在不同水力停留时间下的除磷脱氮性能参数。

Integrated activated sludge system with five tanks for N and P removal is a new facility being developed by Southeast University, which is characteristic of high denitrification and phosphorus removal rate, small space occupation, automatic circulation and convenient operation. Some essentials were introduced, including the components, the operating course and the technological peculiarity. The system was applied for hospital wastewater treatment. Optimal values of denitrification and phosphorus removal were obtained in the trail run, under different HRT.
