摘　　要：外加化学物质对参与硝化反应的两类细菌的抑制作用是不同的,利用这一现象,可实现不经过硝酸盐产物的短程硝化反硝化反应。外加抑制剂会带来新的污染物质,对抑制剂的选择及用量是本研究的重点。当生化处理系统处于完全的短程硝化反硝化过程时,研究了维持此过程所需的条件。The inhibiting actions of two bacteria, which participated in nitrification reaction, by dosing chemicals are different; by utilizing the phenomenon, the shortcut nitrification/denitrification reaction can be realized without nitrate products. As additionally dosing inhibitor shall bring about new pollutants, the selection and dosage of inhibitor are the keys of this study. For this, the conditions needed for maintaining the process were studied when the bio-chemical system was in the process of full shortcut nitrification/denitrification.
