摘　　要：为经济有效的处理胜利油田滨一污水站产生的含油污泥,采用了生物处理技术。在面积为2400m2的预制床中,采取了添加外源石油降解菌剂和生物刺激污泥中土著菌两种手段处理含油污泥。对初始含油量为126g/kg的污泥,经过230d处理,测定了不同处理阶段含油污泥中石油烃总量、不同种类微生物数量和污泥基本理化性质的变化情况,结果表明,添加外源石油降解菌和采取适当措施刺激污泥中土著微生物均能大幅降低污泥中的石油污染物含量、改善污泥的理化性质、降低其生物毒性。Biodegradation technology of petroleum was used to treat the oily sludge in Binyi Oil-Containing Sewage Disposal Station,Shengli oilfield.Two different treatments,i.e.adding extraneous microorganisms and biostimulating the degradation activity of indigenous organisms,were made to treat the oil sludge in a 2 400 m2 prepared bed.The initial content of oil in sludge is 126 g/kg.The content of total petroleum hydrocarbon,the amount of different kinds of microorganisms and the physical and chemical properties of oily sludge were measured in the 230 d treatment course.The results indicates that adding extraneous oil-degradation microorganisms or biostimulating is an effective method to decrease the oil content of sludge,improve the physical and chemical properties and reduce the biotoxicity of oily sludge.
