| 摘 要： | 基于油田注汽锅炉给水的要求,利用商品膜组件,进行了(超滤+纳滤)双膜法深度处理油田采出水的现场试验研究.结果表明,超滤预处理效果良好,出水油的质量浓度小于0.06 mg·L~(-1),SDI_(15)小于4.0,满足了纳滤膜进水要求.氢氧化钠+十二烷基磺酸钠(SDS)复合清洗剂对超滤膜污染表现出较好的清洗效果,纯水通量恢复系数高达92%.在较高的回收率下,纳滤对硬度、总溶解固体(TDS)、SS、和COD仍保持高截留率,且保持了稳定的产水通量,系统出水水质达到油田注汽锅炉进水水质指标.(超滤+纳滤)双膜工艺在长期运行过程中,产水通量及水质表现出较高的稳定性.

| Abstract: | The ultrafiltration(UF) and nanofiltration(NF) processes was used to purify deeply produced water for the in fluent of steam-injected boiler inoil fields.The content of oil in the UF filtrate was less than 0.06 mg.L-1,SDI15was below 4.0,which meet the requirement of the following nanofiltration unit.The NF unit yielded a high hardness,total dissolved solid(TDS),suspended substance(SS) and COD rejection in the case of high recovery rate.The quality of the permeation water came up to the standard of the influ... |
