Abstract:

This research briefly introduced the principles and characteristics of the SAOASP, and detailly discussed the influences of nine parameters on nitrogen removal performance of SAOASP. Current status, application and modification process of SAOASP such as SAOASP-UCT, -SBR, -CAST and -MBR were summarized systematically. Based on the problems of activated sludge process, this paper reviewed different types of biofilm step-feed multi-stage A/O process(SAOBP), including MBBR, BCO, RBC, BAF and FB. Finally, the existing problems and future development trend of step-feed multi-stage A/O process was prospected.

Key words: step-feed, multi-stage A/O process, activated sludge process, biofilm process, biological nitrogen removal

摘要:

简述了活性污泥法分段进水多级A/O工艺(SAOASP)的基本原理与特点,详细探讨了9种参数对SAOASP脱氮性能的影响,系统总结了SAOASP的研究现状、应用情况以及SAOASP改良工艺,包括SAOASP-UCT、SAOASP-SBR、SAOASP-CAST和SAOASP-MBR。基于活性污泥法存在的问题,综述了基于不同类型生物膜法的分段进水多级A/O工艺(SAOBP),包括MBBR、BCO、RBC、BAF和FB。最后对该工艺存在的问题和发展方向进行了展望。
