摘要
介绍了传统脱氮机制与新型脱氮机制-同步硝化反硝化与短程硝化反硝化在曝气生物滤池中的应用,分析了曝气生物滤池脱氮的影响因素与各因素适宜范围,对于曝气生物滤池(BAF)运行参数选择提出了建议,并总结了现阶段的研究现状与不足。认为对BAF系统中生物膜生长和活性、微生物空间分布、反应动力学等研究是现阶段与未来的热点;BAF的改良工艺和组合工艺也需要进一步的改进与完善,探寻具有实际应用价值的工艺系统,对于提高BAF脱氮效能、扩大其应用领域具有重要意义。
Traditional nitrogen removal mechanism and the new nitrogen removal mechanism, simultaneous nitrification-denitrification and shortcut nitrification-denitrification in the application of aeration biological filter were introduced in detail, and the influence factors and the appropriate range of each factors of aeration biological filter were analyzed, and the suggestions for the selection of the operation parameters of aerated biological filter was put forward. The current research status and deficiencies were also summarized. The research of grow and activity of biofilm, microbiological spatial distribution, reaction kinetics in BAF system were considered as the hotspot in present and future. The BAF modified process and combined process was needed to further improvement and perfection. To explore the process system with application value is meaningful to improve denitrification efficiency by BAF and enlarge the application fields.
