摘要
含油污泥是石油生产与加工过程中产生的固体废弃物,含油污泥的有效处理是石油石化行业待解决的关键问题之一.本文介绍了含油污泥的来源、特征及其对环境的影响.从作用原理、处理效果和研究现状等方面,对目前国内外含油污泥处理技术,例如浓缩、脱水等减量化处理技术、热解、热洗、溶剂萃取、超声波等资源化处理技术和焚烧、固化、生物降解等无害化处理技术,进行了详细的论述分析和对比.根据含油污泥性质及处理技术特点,提出了含油污泥处理技术选择方法,该方法以油泥性质为选择标准,挑选多种处理技术相结合,以达到资源化、无害化高效处理含油污泥的目的.并对含油污泥处理技术的近期发展趋势与未来的研究方向进行了展望,以期对含油污泥处理的相关研究提供借鉴.
Oily sludge is a solid waste produced during the production and processing of petroleum.The effective treatment of oily sludge is one of the key problems to be solved in the petroleum and petrochemical industry.In this review,the origin,type,and characteristics of oily sludge were described.From the aspects of technical principle,treatment effect and research status,the current domestic and international oily sludge treatment technologies are discussed,analyzed and compared in detail.For example,reduction treatment technologies such as concentration and dehydration,resource treatment technologies such as pyrolysis,hot washing,solvent extraction and ultrasonic,and harmless treatment technologies such as incineration,solidification and biodegradation,and so on.According to the characteristics of oily sludge and treatment technology,the selection method of oily sludge treatment technology is proposed.This method takes the characteristics of oily sludge as the selection standard and selects a variety of treatment technologies to achieve the purpose of efficient treatment of oily sludge with resource utilization and harmlessness.The recent development trend and future research direction of oily sludge treatment technology have been prospected.It is expected to provide some reference significance for the relevant research on oily sludge treatment.
