| 摘 要： | 采用直接投加菌种的生物强化方式，进行了SEPZ菌生物高效降解炼油污水的实验。考察了菌种浓度、曝气方式、降解温度、初始化学需氧量（COD）等因素对降解效果的影响。在菌种浓度为500μL／L、连续曝气、20℃的优化条件下，降解48h，污水COD从1034．5mg／L降到293．3mg／L，去除率为71．6％；石油类化合物质量浓度从51．58mg／L降到3．31mg／L，去除率为93．6％。

| Abstract: | The refinery waster water was efficiently biodegraded by directly adding bacteria SEPZ and aerating. The effective factors such as content of SEPZ, aeration mode, biodegradation temperature and initial chemical oxygen demand （COD） were investigated. Under the optimal conditions of content of SEPZ 500μL/L, continuous aerating 20℃ and degrading for 48 h, the COD was decreased from 1 034.5 mg/L to 293.3 mg/L （ percent removal of 71.6% ） ,at the same time the content of petroleum compound was decreased from 51. 58 mg/L to 3.31 mg/L（ percent removal of 93.6% ）. |
