摘　　要：化学热洗方法适用于处理以罐底泥和落地含油污泥为主的含油污泥。对某油田以化学热洗为核心技术的含油污泥处理工程所用药剂优化筛选,对于罐底泥和落地含油污泥,可用化学热洗药剂A,搭配离心机絮凝药剂B或者BH阴离子型聚丙烯酰胺;对于含油污泥池表层的生化污泥,可用化学热洗药剂C,搭配KF阳离子高分子絮凝剂。以化学热洗为核心技术的含油污泥处理工程,处理后残渣为灰色块状固体,含油率<2%,达到HJ 607─2011《废矿物油回收利用污染控制技术规范》要求。The method of chemical thermal washing is suitable for the treatment of tank bottom sludge and ground oily sludge.The chemical screening was carried out for an oilfield in which chemical thermal washing was the core technology.For tank bottom sludge and ground oily sludge,chemical heat washing agent A combined with B or BH anionic polyacrylamide as centrifuge flocculant was available.For biochemical sludge,the available thermal washing agent was C which matched KF cationic polymeric flocculant.The treated oily sludge was gray bulk solid and its oil content was less than 2%,showing excellent treatment effect.
