| 摘 要： | OLAND工艺是基于亚硝酸型硝化-厌氧氨氧化脱氮技术而开发的生物脱氮新工艺.该工艺首先采用限制溶解氧浓度实现氨氮的部分亚硝化并实现亚硝酸盐氮的浓度积累,接着进行厌氧氨氧化反应,从而达到去除含氮污染物的目的.与传统生物脱氮工艺相比,该工艺具有耗氧量少、污泥产量少、不需外加碳源等优点.

| Abstract: | OLAND process is the novel biological denitrification process developed based on the nitrous nitrification-anaerobic ammonia oxidation technology. In the process, dissolved oxygen concentration was limited firstly to achieve partial nitrous nitrification of ammonia nitrogen and accumulate the nitrite nitrogen, which was followed by the anaerobic ammonia oxidation for the purpose of removing nitrogen-containing pollutants. As compared with the conventional biological denitrification, the novel process has the advantages of less oxygen consumption, less sludge production, and no carbon to be added. |
