Directing against the charactors of oily waste water in Zhanjiang Orimulsion Oil Fired Power Plant,through test,it is finally determined to use extraction wethod for treatment of the oily waste wa-ter. The treatment system and technological process for oily waste water in Zhanjiang Orimulsion Oil Fired Power Plant have been presented. The extractant selected for said technology is diesel oil no. 1, supplementing with a specially prepared additive,and adopting BZH type treatment equipment for oily waste water. Under condition that the concentration of common mineral oil is equal to or less than 10%,or the concentration of orimulsion oil is equal to or less than 5 g/L,the waste water after treat-ment can attain the required standard for dischaging.%针对湛江奥里油电厂含油废水的特性,通过试验最终确定采用萃取法对其进行处理.介绍了湛江奥里油发电厂含油废水处理系统及工艺流程,该工艺所选萃取剂为0号柴油,辅以专配添加剂,采用BZH型含油废水处理设备.在含油废水中普通矿物油浓度小于或等于10%及奥里油浓度小于或等于5 g/L时,处理后的废水可达标排放.
