  • 摘要: 在成功实现生活污水短程生物脱氮的基础上，采用体积为3 L的小试反应器，利用在线DO监测手段控制DO=1.0 mg·L-1，通过投加NaNO2的方式控制系统初始NO2--N=40 mg·L-1，以丙烯基硫脲（ATU）抑制NH4+-N的氧化过程，考察了生物脱氮好氧阶段不同反应过程中N2O的产生量。结果表明，除缺氧反硝化细菌的反硝化过程外，好氧条件下，氨氧化菌（AOB）能够以NH4+-N作为电子供体，NO2--N作为电子受体，进行反硝化脱氮过程，其反硝化产物为N2O。生物脱氮好氧阶段AOB的好氧反硝化和异养菌的缺氧反硝化反应中，N2O的产量分别占分别占进水总氮（NH4+-N+NO2--N）的7.23%和7.80%。好氧阶段NH4+-N和NO2-的氧化过程中，几乎没有N2O的产生。
    Abstract: Contributions of NH4+ oxidation,NO2- oxidation,and heterotrophic and nitrifier denitrification during the N-removal process were investigated in a lab-scale nitrifying reactor.Allylthiourea (ATU) was used to inhibit NH4+ oxidation and investigate processes under nitrifying conditions.The results confirmed that besides heterotrophic bacteria,ammonium-oxidizing bacteria (AOB) could undertake denitrification processes,with NH4+ as the electron donor,NO2- as the electron acceptor,and N2O as one of the final products.The relative contribution of the heterotrophic and nitrifier denitrification to total N2O emission was 51% and 47%,respectively.Little N2O was emitted during the NH4+ and NO2- oxidation processes.
