三相生物流化床处理含油废水的试验研究

Research on three phase biological fluid bed treating oil wastewater

我国油田含油废水现利用传统的隔油、混疑、过滤 (老三套 )处理工艺 ,出水指标达不到国家的二级排放标准。为提高含油废水处理水平 ,在“老三套”基础上添加了生物处理部分 ,即三相生物流化床。为强化生物处理 ,采取了投加漂浮填料和悬浮填料的强化处理措施 。

The traditional treatment technology, such as oil removal, coagulation and filtration (Old Three Sets) are utilized in treating oily wastewater from oilfield of our country. All indexes of effluent cannot reach the secondary standard of GB8978-1996. Biological treatment part (that is three phase biological fluid bed) was added on the base of Old Three Sets so as to produce much effect on oily wastewater. To strengthen biological treatment, strengthened measures such as adding floated packings and suspended fillings are taken. The effluent can reach the secondary standard of GB8978-1996.\;
