- 摘要:
- Anammox技术的应用因电子受体NO2--N难以稳定获取而受到限制,研究表明,部分自养反硝化是获取NO2--N积累的有效途径。分别论述了以还原态硫(S0、硫化物)、CH4、H2作为电子供体应用于自养反硝化时对NO2--N积累的影响因素和存在的问题,并介绍了相关微生物及反应酶,以期为自养反硝化耦合Anammox时电子供体的选择提供参考。结果表明,以还原态硫为电子供体的反硝化安全、经济,但存在二次污染的风险;以CH4为电子供体的反硝化环保、无毒,但安全性及传质效率低;以H2为电子供体的反硝化无二次污染,安全性及传质效率同样较低,CH4和H2皆可利用膜生物膜反应器(MBfR)提升传质效率。
- Abstract:
- The application of Anammox technology is limited by the difficulty of obtaining stable electron acceptor NO2--N , and studies have shown that partial autotrophic denitrification is an effective way to obtain NO2--N accumulation. The influencing factors and existing problems of NO2--N accumulation in autotrophic denitrification using reduced sulfur (S0, sulfide), CH4 and H2 as electron donors were reviewed, and the related microorganisms and enzymes were introduced, providing the reference for the selection of electron donors in autotrophic denitrification coupled Anammox. The results show that denitrification using reduced sulfur as electron donor is safe and economical, but there is a risk of secondary pollution; denitrification using CH4 as electron donor is environmentally friendly and non-toxic, but its safety and mass transfer efficiency are low; denitrification with H2 as electron donor has no secondary pollution, low safety and mass transfer efficiency, MBfR can promote mass transfer for the denitrification with H2 or CH4 as electron donor.
