摘要
含油污泥是原油加工过程中产生的油和污泥混合物的生产和收集。它含有原油、重金属、有机毒素和有害物质。其特点是含水量高、流动性差、体积大。回收和处置一直是石油工业环境保护的重要方面。因此,含油污泥的安全处理尤为重要。水热氧化技术是一种新型的、综合性的、无二次污染的含油污泥处理技术。本文介绍了湿式氧化和超临界水氧化的基本原理和研究进展,重点介绍了含油废水处理的最新实验研究、优缺点和发展前景。
Oily sludge is the production and collection of the mixture of oil and sludge produced during crude oil processing.It contains crude oil,heavy metals,organic toxins and harmful substances.It is characterized by high water content,poor fluidity and large volume.Recovery and disposal have always been an important aspect of environmental protection in petroleum industry.Therefore,the safe treatment of oily sludge is particularly important.This paper mainly introduces the basic principles and research progress of wet oxidation and supercritical water oxidation,with emphasis on the latest experimental research,advantages and disadvantages and development prospects of oily wastewater treatment.
