Nitric oxide (NO) may participate in the ozone layer depletion and forming of nitric acid. Abiotic and biological mechanisms of NO removal from waste gases were studied in a biotrickling filter. The abiotic NO removal rate in the biotrickling filter was estimated by a review of the literature. The abiotic and biological removals were also verified in the biotrickling filter. The result has shown that chemical oxidation and bionitrification were both involved in the NO removal. It was found that the NO removal in high concentration (approximately 1000 ppm or higher) was in large measure the result of abiotic removal in both gas-phase and liquid-phase reactions. When NO concentration is low (less than approximately 100 ppm), bionitrification was the main process in the NO removal process in the biotrickling filter.
一氧化氮（NO）可能参与臭氧层损耗和硝酸的形成。在生物滴滤塔中研究了从废气中去除NO的非生物和生物机制。通过文献综述估算了生物滴滤塔中的非生物NO去除率。还在生物滴滤塔中验证了非生物和生物去除效果。结果表明，化学氧化和生物硝化作用均参与了NO的去除。研究发现，高浓度（约1000 ppm或更高）的NO去除在很大程度上是气相和液相反应中非生物去除的结果。当NO浓度较低（小于约100 ppm）时，生物硝化作用是生物滴滤塔中NO去除过程的主要过程。
