国内外含油污泥处理技术研究进展

Progress in oily solid waste treatment technology at home and abroad

含油污泥是来源于石油开采、运输、炼制及含油污水处理过程中的含油固体废物。主要介绍了国内外含油污泥处理技术的研究现状及进展,含油污泥的处理技术可分为2类,即生物法和非生物法。生物法主要包括生物地耕法、生物强化法和生物浮选法。非生物法主要包括高温蒸气法、溶剂萃取法和离心分离法等。对各种方法进行了评价和比较,并对含油污泥处理技术今后的发展提出了建议。

The oily sludge comes from the oily solid waste of oil exploration, transportation, refining, and oily wastewater treatment process. In this paper the research status and development of oil sludge treatment technology at home and abroad are mainly introduced. Oily sludge treatment technology can be divided into two categories, namely biological and non-biological methods. Biological methods includes biological tillage, strengthen biological methods and biological flotation. The non-biological methods include high temperature vapor extraction, solvent extraction and centrifugal separation. The comparison of various methods is performed. The suggestions for the future development of the oil sludge treatment technology are put forward in the end.
