Abstract:

An engineering example of treating the urban domestic sewage by A/O process is introduced. The result shows that this process has the characteristics such as less land occupied, convenient to operate and manage, and the effluent can be used for landscape, greenbelt and car-washing, etc. The project is considered cost effective and benefit to society and environment. The removal rate of COD_Cr is 78% and the removal rate of BOD₅ is 92%. Therefore, it is a more ideal process to treat the urban sewage.

Key words: anaerobic process, aerobic process, domestic sewage

摘要：

介绍了A/O工艺处理城市生活污水的工程实例。实践表明，该工艺占地面积小，运行管理简单，出水可用做绿化、洗车及景观用水，社会、环境效益均较显著。COD_Cr去除率达78%，BOD5去除率达92%。是处理城市生活污水较理想的工艺选择。
