7、、环境和工业建设不协调,导致基础设施长期超负荷承载。全国绝大多数城市的污水处理能力远远满足不了实际需要。污水的处理能力取决于两点：一是城镇污水处理厂的规模，二是处理效率。后者涉及到污水处理工艺的选择、设计与优化运行。目前,城市污水处理主要采用生物活性污泥法。生物活性污泥法有多种处理工艺,城市二级污水处理厂常用的工艺方法有:普通曝气法、A-B法(二段曝气法)、A/O除磷工艺、A/O脱氮工艺、A2/O除磷脱氮工艺、氧化沟工艺等。已有的生物除磷脱氮工艺可分成A/O系列、氧化沟系列和序批式反应器(SBR)系列

8、等。随着各个系列不断地发展和改进,形成了目前的较典型的工艺,如A/O工艺、A2/O工艺、改良A2/O、倒置A2/O工艺、ORBEL氧化沟工艺、百乐克工艺等。1.A/O工艺A/O工艺是Anoxic/Oxic(缺氧/有氧)或Aner2abic/Oxic-35-水控综合实验报告06级环境3班杨梅20066626(厌氧/好氧)工艺的缩写,是为污水生物除磷脱氮而开发的污水处理技术。目前典型的A/O工艺是把缺氧单元提前到好氧单元前,利用进水中的有机物作为碳源,称之为
