摘　　要：目前,城镇污水集中处理存在处理要求高、排污分散、进水水质和水量波动大等特点。以广东省某城镇污水处理厂工艺设计为例,本文结合实际情况,重点对传统厌氧-缺氧-好氧法(A2O)、循环活性污泥法(CASS)、A2O微曝氧化沟等工艺进行比选,最终选择A2O微曝氧化沟作为本工程的污水处理工艺。实践表明,该工艺运行效果好,可以为类似工程的设计提供参考。At present,the centralized treatment of urban sewage has the characteristics of high treatment requirements,scattered sewage,and large fluctuations in the quality and quantity of influent water.Taking the process design of an urban sewage treatment plant in Guangdong Province as an example,combined with the actual situation,this paper focuses on the comparison and selection of traditional anaerobic-anoxic-aerobic method(A2O),cyclic activated sludge system(CASS),and A2O micro-aeration oxidation ditch,and finally chooses A2O micro-aeration oxidation ditch as the sewage treatment process of this project.Practice shows that the process works well and can provide reference for the design of similar projects.
