摘　　要：许多小型污水处理厂的处理和排放标准已无法满足标准要求,必须积极探讨小型污水处理厂的提标改造设计方案,采用科学的污水处理工艺提标改造。文章对南方某污水处理厂提标改造工程展开分析,结合其排水现状,从建设规模、设计进出水水质和改造思路方面进行改造方案设计,并对A^(2)/O生化池(生物填料强化)+活性砂滤池方案和MBR工艺方案进行比较,最终得出前者更适合在此工程中应用。The treatment and discharge standards of many small sewage treatment plants have been unable to meet the standard requirements.It is necessary to actively explore the design scheme of upgrading and reconstruction of small sewage treatment plants,and adopt scientific sewage treatment process for upgrading and reconstruction.The upgrading and reconstruction project of a sewage treatment plant in southern China is analyzed.Combined with its drainage status,the reconstruction scheme is designed from the aspects of construction scale,design of inlet and outlet water quality and reconstruction ideas.The A^(2)/O biochemical tank(biological filler enhancement)+active sand filter scheme and MBR process scheme are compared.Finally,it is concluded that the former one is more suitable for the application in this project.
