摘要
以孔径为0.1μm的碳化硅陶瓷膜,在跨膜压差0.2MPa、温度20℃、伴有固定时间间隔的反冲洗浓排条件下,通过死端过滤处理含油废水。结果表明,膜通量大,出水质量满足《碎屑岩油藏注水水质推荐指标及分析方法》标准(SY/T-532994)的要求,可以作为回注水;且膜简易清洗后,通量可100%恢复。
Under the conditions of temperature of 20℃ and transmembrane pressure（ΔTMP） of 0.2MPa,a silicon carbide ceramic membrane with a pore size of 0.1μm was introduced to treat oil wastewater with the dead end filtration method in conjunction with a periodical backwash technique.The membrane was found to exhibit high flux,and the quality of the permeate can meet the standards of the recommended ＂SY/T5329-94 of Injection Water Quality for Detrital Rock Oil Reservoirs and Analyzing Methods＂ of China.Especially,the membrane is easy to be cleaned,and membrane flux recovery can reach 100%.
