It is found that HRT, influent ammonia nitrogen and external carbon source have significant effect on biological nitrification and denitrification.
通过试验发现HRT、进水氨氮和外碳源对生物硝化和反硝化有重要影响。
Based on traditional biological nitrogen removal theory, nitrogen removal involves nitrification of ammonia to nitrate or nitrite followed by denitrification of nitrate or nitrite to nitrogen gas.
依据常规生物脱氮原理，脱氮过程包括将氨氮氧化为硝酸盐氮或亚硝酸盐氮的硝化反应和将硝酸盐氮或亚硝酸盐氮还原为氮气的反硝化反应。
The direct affected factor of nitrification was ammonia nitrogen loading.
氨氮负荷是影响反应器硝化性能的直接因素。
