| 摘 要： | 针对已建炼化污水处理装置提质达标的需求，采用旋流强化工艺对缺氧-好氧（A/O）池进行改造，生化出水TN由（32.8±8.9）mg/L降至（25.6±5.7） mg/L，TN平均去除率提高了约10百分点，且出水TN达标率达到100%，出水水质稳定达到GB 31570—2015《石油炼制行业污染物排放标准》的TN排放限值要求。旋流强化工艺技术先进，便于实施，适用于石化行业污水处理装置的改造升级，具有广泛的应用前景。

| Abstract: | In order to meet the demand of improving the effluent quality of the established refinery sewage treatment plant，the anoxic-aerobic （A/O） pool was retrofitted with the cyclone strengthening process. TN of the effluent after biochemical treatment was reduced from （32.8±8.9） mg/L to （25.6±5.7） mg/L，the average TN removal rate increased by about 10 percentage points，and the standard-meeting rate of effluent TN reached 100%. The water quality of the effluent reached the TN emission limit of GB 31570-2015. The advanced and convenient cyclone strengthening technology is suitable for upgrading of petrochemical sewage treatment plant and has a wide application prospect. |
