【摘要】 在除磷与脱氮的联合工艺中,由于两过程所涉及的微生物在性质及最佳代谢条件上有较大差别,在同一处理流程中很难达到协调而稳定地运行问题,在传统生物除磷工艺原理基础上,就新近发现的A2/O反硝化除磷技术新工艺及其微生物学原理特点,重点介绍A2/O反硝化除磷过程中的缺氧阶段中以NO3-作为最终电子受体时,厌氧条件下释磷规律,缺氧条件下磷的去除效果以及缺氧阶段氮的变化情况。更多还原

【Abstract】 There exist big differences on the characteristics and optimal metabolic condition of microorganisms in the processes of dephosphorization and desulphurization,so it is hard to reach the coordinated and stable operation in the same process.Based on the traditional microbiological dephosphorization techniques,A²/O denitrifying dephosphorization technique has been newly found out and especially some introductions are made to phosphorus removal rules under anaerobic condition,the removal efficiency of phosphor under condition of meager oxygen and the change of nitrogen in oxygen shortage stage when NO^-₃is regarded as the final electronic receptor in the oxygen shortage stage of A²/O denitrifying dephosphorization process.更多还原
