稠油开采微生物的生理生化特征及其对原油特性的影响

, 2007
从原油及含油污水中分离并培育出一株能有效地降解稠油中重质组分的菌株3-28,其生理生化特征和分子鉴定结果表明,该菌株属于微杆菌属(Microbacterium)。用该菌株对渤海和新疆等油田的稠油进行了微生物降解实验,分析了细菌降解对原油粘度等物理特征的改变及其对饱和烃、芳烃以及胶质、沥青质各组分在原油中相对含量和内部组成的影响。结果表明,该菌株降解作用使原油性质发生了明显变化:渤海绥中36-1油田的原油粘度降低24.9%,凝固点降低5.2℃;克拉玛依油田的原油粘度降低32.4%,凝固点降低7.7 ...

微生物菌剂处理炼油废水的工程设计

, 2010
炼油废水具有污染物浓度高、水质波动大、可生化性差等特点,采用常规生物处理,难以稳定达标。采用"高效微生物+生物模块"工艺路线,应用石油降解菌剂、硝化菌剂和与之匹配的工艺,处理炼油废水,出水水质稳定达到GB8978-1996《污水综合排放标准》一级标准,对COD和NH3-N的平均去除率分别为94.2%和93.1%。该工艺具有抗冲击负荷强、运行费用省、出水水质好等优点 ...
