摘要
在剖析倒置A2/O典型工艺及其设计方法的基础上,针对工艺中存在的单向污泥回流比低、无混合液回流、反硝化效率低等主要技术问题,以及由此引起的对厌氧池容积(或HRT)、出水水质达标的影响,提出改进设计的建议,并通过对工程实例的核算,论证了改进工艺及其设计方法的合理性,从而为城镇污水处理工程的改进设计提供了参考。
Aimed at the main technical problems existing in typical reversed A^2/O process, such as low one-way sludge return ratio, no mixed-liquor return, low denitrification efficiency and so on, as well as their influence on volume of anaerobic tank （ or HRT） and standard effluent quality, the suggestions for improvement in design are put forward on the basis of analyzing the process and its design method. The rationality of the improved process and its design method is demonstrated by calculating an engineering case, which provides reference for improved design of municipal wastewater treatment projects.
