| 摘 要： | 对缺氧生物吸附活性污泥法(ABSAS)生物脱氮系统中的硝化作用进行了分析和讨论,研究结果表明,有机物氧化优先于硝化作用,有机物对硝化作用的影响主要表现在异养氧化菌对硝化菌的竞争性抑制。但生物脱氮工艺中的初级缺氧反应对硝化作用有一定的促进作用,而且初级缺氧段中的反硝化作用愈强,则由缺氧段进入好氧段后,硝化作用进行的愈强,此特性可用于生物脱氮工艺的设计中,以提高硝化作用能力。

| Abstract: | The nitrification in the Anoxic Bio-Sorption Activated Sludge (ABSAS) process for nitrogenremoval was analyzed and discussed.The results show that the effect of organic substances to the nitrification is mainly the competed inhibit of heterotrophic bacteria to nitrification bacteria;the first anoxic reaction could improve the nitrification;this feature could be used in designing nitrogen removal process so as to improve nitrification. |
