| 摘要: |
| 采用“化学热洗-生物处理”工艺对石油炼厂含油污泥进行了研究。研究表明：通过化学热洗可将含油量为29．0％的含油污泥洗涤至残油含量为2.7％，污油回收率可以达到92．2％，体积可减少16％，洗涤产生的废水可进行回用，重新用作污泥洗涤用水；而且经洗涤后的污泥可直接进行生物处理，在经好氧生物处理40天后，石油类去除率可达95％。 |

| Abstract: |
| In this paper, the treatment of oily sludge is researched with "chemico- heated washing & bio logical treatment" technology. The results show that the oil content of the sludge can decrease from 29.0 % to 2.7 % by chemico-heated washing, and the recovery |
