摘要
短程硝化反硝化脱氮工艺,具有节省曝气量和反硝化碳源、缩短水力停留时间、污泥生成量小、反应器容积小、占地面积小等优点,是目前国内外研究的热点。本文分析讨论了传统生物脱氮和短程硝化反硝化脱氮的原理,分析了温度、溶解氧、pH值、游离氨、碳氮比对短程硝化反硝化的影响。
Shortcut nitrification and denitrification has a lot of advantages,such as saving oxygen supply and carbon,reducing HRT and sludge production,having small reactor and cover a smal area and so on. Shortcut nitrification and denitrification is a hot point for study recently in China and abroad. This paper briefly discussed the mechanism of traditional biological nitrogen removal technique and shortcut nitrification and denitrification,analysised the influence of temperature,DO,pH,free ammonia and C / N on shortcut nitrification and denitrification.
