摘要
改良A2/O污水厂工艺运行稳定,具有较强的抗冲击性能,出水水质优于设计标准。平均进水COD为433mg/L时,平均出水COD为58.8mg/L,平均COD去除率达到86.3%,平均BOD5去除率达到91.8%,平均NH3-N去除率达到88.5%,平均TP去除率达到81.1%,均达到国家GB18918-2002污水排放一级B标准。
Modified A2/O process showed stable performance, good ability of resisting shock loading and superior water quality to designed standards. When the COD concentration of the influent was 433mg/L, the COD of the influent was 58.Smg/L. The COD removal rate of the system was 86.3%, BOD5 of 91.8%, NH3-N of 88.5%, and TP of 81.1% .All of them could reach the I-B criteria specified in discharge standard of Pollutants for municipal Wastewater treatment plant （GB18918 - 2002）.
