【摘要】：油田含油污水的高效處理是油田可持續(xù)開發(fā)的關鍵,陶瓷膜過濾技術由于具有分離效果好、無二次污染等優(yōu)點已成為目前的研究熱點。本文分析了陶瓷膜的油水分離機理,調研了國內外陶瓷膜過濾技術處理油田含油污水的研究現(xiàn)狀,同時介紹了陶瓷膜過濾技術在海上油田含油污水處理中的應用,重點分析了膜分離效果的影響因素,主要包括膜本身的性能、原料液的性質、過程的操作參數(shù)以及其他影響因素。其中膜本身的性能主要體現(xiàn)在膜孔徑和膜材料上;原料液的性質主要取決于含油量、p H、濃度和溫度;而過程的操作參數(shù)主要包括跨膜壓差和膜面流速;其他因素主要有反沖洗、吸附劑和混凝劑。然后分析了膜污染的機理,介紹了目前膜清洗的方法。最后分析了膜技術應用中存在的問題,對未來研究的方向提出了幾點建議。
[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.
