摘　　要：对炼油废水中乳化态石油进行了生物除油研究．分离筛选了一组降解石油的微生物，并培养形成性能良好的活性污泥菌剂，在２ Ｌ的好氧反应器中用６ ～１０ ｈ 时间把废水中１４０ ｍｇ Ｌ－ １ 的乳化态石油降解到３０ ｍｇ Ｌ－ １ 以下，同时去除６０ ％ 左右 Ｃ Ｏ Ｄ；整个处理过程不产渣、不排泥，处理效果良好．The biodegradation of refinery wastewater containing emulsified crude oil was studied. A group of oil degrading microbes was separated and a good active sludge was cultured. The emulsified crude oil in the wastewater was degraded from 140 mg L -1 to less than 30 mg L -1 after 6～10 h, while about 60% COD Cr was removed. Oil residue and waste sludge were not produced during the whole treatment process. The treatment was greatly efficient. This study provides a practical method and scientific basis for substituting biodegradation for floatation in oil the treatment of emulsified crude.
