摘要:

随着工业技术的快速发展,在石油开采、交通运输等生产过程产生的大量含油废水,具有排量大、成分复杂、生物降解性能差等特点,未经恰当处理排放入环境中,会对人体健康和生态环境造成巨大的危害。磁絮凝是一种新兴的水处理技术,在降低浊度、去除磷酸盐、有机物等领域已被证明具有显著效果,在水处理领域呈现出很好的应用潜力。文章系统综述了磁絮凝在含油废水处理中的应用研究进展,具体介绍了含油废水的来源及特性、磁絮凝的分类、工艺条件、在含油废水处理中的应用以及磁絮凝材料的回收利用,并对当前磁絮凝在处理含油废水领域的研究进行了简要介绍。最后从磁性材料、适用范围、多工艺耦合联用等方面对磁絮凝的发展方向进行了展望。

Abstract:

With rapid development of industrial technology, large amount of oily wastewater has been generated in the processes of oil exploitation, transportation, etc. Oily wastewater is characterized by large discharge, complex composition, and poor biodegradation. If it is discharged into the environment without proper treatment, it will cause great harm to human health and the ecological environment. In view of the current situations such as water scarcity, serious environmental pollution and increasingly stringent emission standards, how to deal with oily wastewater is one of the research hotspots in the field of water treatment. Magnetic flocculation is a new water treatment technology, which has been proven effective in the fields of turbidity reduction, phosphate removal, and organic compound removal. Therefore, magnetic flocculation shows great application potential in the field of water treatment. Herein, the research progress of magnetic flocculation in oily wastewater treatment was systematically reviewed. Firstly, the sources and characteristics of oily wastewater were introduced, and the classification of magnetic flocculation was presented. Then, the preparation of magnetic materials, the process conditions when applied in oily wastewater treatment, and the recycling of magnetic flocculants were specifically introduced. Moreover, the current research on magnetic flocculation in the field of oily wastewater treatment was briefly introduced. Finally, the development direction of magnetic flocculation was prospected from the aspects of magnetic materials, application range, multi-process coupling, etc., in the hope of a broader application in the treatment of oily wastewater.

Key words: coagulation, magnetic flocculation, wastewater, emulsion, oil-water separation
