含油污泥离心处理技术研究进展

Research Progress in Centrifugal Treatment Technology of Oily Sludge

含油污泥,简称油泥,是在石油开采、运输、炼制及含油污水处理过程中产生的含油固体废物。油泥中含有数百种有毒有害化合物,美国环保署将其列为优先污染物,我国也将油泥列入国家危险废物名录。目前,我国含油污泥的产量巨大,油泥以及由油泥引起的污染土壤的无害化处理已成为一个亟待解决的科学和技术问题。主要介绍了国内离心技术处理含油污泥研究的现状及进展,对这些方法进行了评价和比较,并对今后的研究方向提出建议。

The oily sludge is oily solid waste from the process of oil transportation, exploitation, refining, and oily wastewater treatment. Oily sludge contains hundreds of toxic compounds, so the United States Environmental Protection Agency listed it as priority pollutants and China also listed the oily sludge in the national hazardous waste list. At present, Chinese oil sludge yield is huge, then harmless treatment of oily sludge and soil pollution caused by oily sludge has become an urgent subject of science and technology. In this paper, status and research progress of the centrifuge treatment technology of oily sludge were introduced, and these methods were evaluated and compared.
