摘　　要：多级A/O工艺目前在国内市政和部分工业污水处理领域应用较多,具有预处理和污泥处理系统简单,污泥负荷低、处理效果好且稳定,投资低,曝气系统效率高、运行成本较低,维护管理简便等特点,但是在实际运行中也发现存在一些问题,如土池结构不适合地下水位高的地区的局限性,沉淀池效果较差、稳定池多余占地且污泥淤积难以清除,关键设备国产质量有待提高,工业污水处理少数水质指标偏高,需要设计人员选择适合其条件的场合应用,并进一步总结、改进和完善。Multilevel A/0 teehnology is mostly applied in the fields of domestic munieipal works and partial industrial sewage treatment, It is characterized by pretreatment and sluge disposal facility with low sludge loading, stable effect, low investment, effective aeration system, low operating cost and portable maintenance. However, there still exits some problems during the practi- cal operation, such as the problem of tank eonstruetion which is unadapted in the area with higher groundwater level, ineffective desilter, redundant stability tank and hard to get rid of silting sludge, the quality of domestic key equipment needs to be improved, and few of water quality index are on the higher side in industrial wastewater treatment. So it is needed that the designer should select appropriate site to apply the teehnology with subsequent further summarization and improvement.
