摘要
1975年Voet发现了在硝化过程中亚硝氮积累的现象,首次提出了短程硝化反硝化生物脱氮理论,1986年Sutherson等证实了短程硝化的可行性。相比于传统硝化反硝化工艺,短程硝化反硝化可减少需氧量和有机碳源,缩短系统水力停留时间,降低污水处理运行费用和基建投资等。鉴于短程硝化反硝化的诸多优点,该工艺引起了污水处理领域的广泛关注,本文对短程硝化反硝化的原理、优点以及国内外应用现状进行了简要概述。
In1975,Voet discovered the phenomenon of nitrite accumulation during nitrification.For the first time,the theory of shortcut nitrification and denitrification was studied.In1986,Sutherson confirmed the feasibility of shortcut nitrification.Compared with the traditional nitrification and denitrification process,shortcut nitrification and denitrification could reduce the oxygen demand and organic carbon source,shorten the system hydraulic retention time,reduce the sewage treatment costs and infrastructure investment.In view of the many advantages of shortcut nitrification and denitrification,this process had aroused widespread concern in the field of wastewater treatment.In this paper,the principle,advantages and current research status of shortcut nitrification and denitrification were briefly summarized.
