简介:摘 要:含油污泥属于危险废物,主要来自于石油行业。含油污泥是一种富含矿物油的多相分散体系,组成复杂,是由黏土颗粒、有机质、絮体、微生物及其代谢产物、矿物质等混合形成的污泥。含油污泥来源于石油开采、集输和炼油过程中产生,含油污泥主要影响石油化工行业和环境。国内外油田含油污泥的主要处理方法包括萃取、机械分离、超声波、微波填埋、焚烧、裂解、化学热洗、固化、堆肥、调剖等处理方法。每种处理方法均有各自的优缺点和适应性,对含油污泥进行分级处理和对处理方法进行分级是今后研究的主要方向。本文针对石油行业含油污泥处理现状,通过已应用的含油污泥处理技术对比,对其应用的含油污泥的类别进行分析,选择最佳的处理技术。
