浅析几种城市污水处理工艺

Comparison on several urban sewage treatment process

针对城市污水的特点,根据污水处理工艺时应遵循的原则,介绍了城市污水处理的A2/O工艺、AB法工艺、卡鲁塞尔氧化沟工艺、改良的SBR类工艺、生物曝气过滤工艺、一体化氧化沟工艺、奥贝尔氧化沟工艺等7种常用城市污水处理工艺原理、工艺流程,并对各种工艺的优缺点进行了分析.

Sewage treatment processes are much in recent years.The process selection is the key factor for the urban sewage treatment efficiency.Aimed at the sewage characteristics and combined with the principle of selecting sewage treatment process,the urban sewage treatment process and principle such as A2/O process,AB process,Carrousel process,SBR process,BAF process,Icog process and Orbal process are introduced in this paper.The advantages and disadvantage of every process are analyzed for providing the reference in selecting sewage treatment process.
