【摘要】：油田含油污水的高效处理是油田可持续开发的关键,陶瓷膜过滤技术由于具有分离效果好、无二次污染等优点已成为目前的研究热点。本文分析了陶瓷膜的油水分离机理,调研了国内外陶瓷膜过滤技术处理油田含油污水的研究现状,同时介绍了陶瓷膜过滤技术在海上油田含油污水处理中的应用,重点分析了膜分离效果的影响因素,主要包括膜本身的性能、原料液的性质、过程的操作参数以及其他影响因素。其中膜本身的性能主要体现在膜孔径和膜材料上;原料液的性质主要取决于含油量、p H、浓度和温度;而过程的操作参数主要包括跨膜压差和膜面流速;其他因素主要有反冲洗、吸附剂和混凝剂。然后分析了膜污染的机理,介绍了目前膜清洗的方法。最后分析了膜技术应用中存在的问题,对未来研究的方向提出了几点建议。
[Abstract]:The efficient treatment of oil-bearing wastewater is the key to the sustainable development of oil field. The ceramic membrane filtration technology has become a research hotspot because of its advantages of good separation effect and no secondary pollution. The oil and water separation mechanism of ceramic membrane is analyzed in this paper. The present situation of ceramic membrane filtration technology for treating oil-bearing wastewater in oil field was investigated. The application of ceramic membrane filtration technology in treatment of oil-bearing wastewater in offshore oil field was introduced, and the influencing factors of membrane separation effect were analyzed. It mainly includes the performance of the membrane itself, the properties of the raw material, the operation parameters of the process and other influencing factors, among which the performance of the membrane itself is mainly reflected in the pore size of the membrane and the membrane material. The properties of the raw liquid mainly depend on the oil content, concentration and temperature; the operating parameters of the process mainly include the transmembrane pressure difference and the membrane surface velocity; other factors mainly include backwashing, adsorbent and coagulant. Then, the mechanism of membrane fouling is analyzed. The methods of membrane cleaning at present are introduced. Finally, the problems existing in the application of membrane technology are analyzed, and some suggestions for future research are put forward.
