摘要
介绍了基于反硝化除磷理论的双污泥工艺(A2N工艺),分析了传统双污泥工艺的优点和影响因素。摒弃了固有工艺流程冗长,基建费用过高;工艺出水氨氮过高等缺陷。在深入分析的基础上,设计了新型的双污泥工艺,缩短了工艺流程,提高了出水水质。改进后的工艺不仅可以解决同步脱氮除磷的问题,而且可用于再生水的生产。目前该工艺正在小试中,运行良好。
The A2 N process which is based on the theory of denitrifying phosphorus removing is introduced, and the strong points and shortcomings of this process is analysed is introduced. The shortages of the conventional A2 N process： too long process, high investment fair; ammonia in effluent may exeed the standard are spurn. After the research of the original process, the lab - scale research on the improved process is initialed, which shortens the original process and improves the effluent standard. The improved process is suitable for the denitrifying phosphorus removaling and sewage regeneration. The lab - scale research of the new process is working well.
