| 摘 要： | 亚硝酸盐作为生物硝化和反硝化的中间产物, 存在于污水生物脱氮除磷系统中。对于生物强化除磷工艺亚硝酸盐既是电子受体用于反硝化除磷, 同时又是抑制剂影响生物除磷过程。本文综述了聚磷菌在厌氧、好氧和缺氧环境中的代谢机理, 在此基础上分别从好氧除磷和反硝化除磷两方面介绍了亚硝酸盐对污水生物除磷影响的研究, 同时概述了亚硝酸盐对生物除磷的抑制机理, 并对该领域的研究提出了个人见解。

| Abstract: | Nitrite (NO2-) exists in the biological phosphorus and nitrogen removal system as an intermediate in the biological oxidation of ammonia to nitrate and reduction of nitrate to nitrogen. In enhanced biological phosphorus removal (EBPR) processes, nitrite is an electron acceptor used by denitrifying phosphorous removal bacteria and also an inhibitor to biological phosphorus removal process. This paper reviews metabolic mechanism of phosphorus accumulating organisms (PAOs) under anaerobic, aerobic and anoxic conditions separately. The effect of nitrite on biological phosphorus removal as well as inhibition mechanism of nitrite was introduced. The personal opinions were also suggested. |
