摘要
为了提高油气田含油污水的处理效率,降低化学药剂的使用量,避免处理过程中二次污染现象,以西部某油田含油污水为研究对象,开展了陶瓷膜处理油气田含油污水的实验研究,主要考察了陶瓷膜孔径、跨膜压差、膜面流速以及工作温度对含油污水处理效果的影响。结果表明:陶瓷膜的孔径越大、跨膜压差越大、膜面流速越大以及工作温度越高,实验用含油污水经过陶瓷膜过滤处理后的含油量、悬浮物质量浓度以及粒径中值均逐渐增大。当选择陶瓷膜的孔径为0.05μm、跨膜压差为0.1 MPa、膜面流速为3 m·s^(-1)、工作温度为30℃时,含油污水经过处理后的含油量可降低至3.65 mg·L^(-1),悬浮物质量浓度为0.68 mg·L^(-1),粒径中值为0.71μm,均能达到标准SY∕T 5329—2012中的注入水水质控制标准要求。
In order to improve the treatment efficiency of oil-bearing sewage in oil and gas fields,reduce the use of chemical agents,and avoid secondary pollution in the treatment process,an experimental study was carried out on the treatment of oil-bearing sewage in oil and gas fields with ceramic membrane,taking the oil-bearing sewage in an oil field in the west as the research object.The effects of ceramic membrane aperture,transmembrane pressure difference,membrane surface flow rate and working temperature on the treatment effect of oil-bearing sewage were mainly investigated.The experimental results showed that the larger the pore diameter of ceramic membrane,the higher the transmembrane pressure difference,the higher the membrane surface flow rate,and the higher the operating temperature,the larger the oil mass concentration,suspended solid mass concentration and median particle size of the experimental oily sewage after filtering by ceramic membrane.When the aperture of ceramic membrane was 0.05μm,the transmembrane pressure difference was 0.1 MPa,the membrane flow rate was 3 m·s^(-1),and the operating temperature was 30℃,after treatment,the oil mass concentration of oily wastewater was reduced to 3.65 mg·L^(-1),the suspended solid mass concentration was 0.68 mg·L^(-1),and the median particle size was 0.71μm.All met the requirements of the injection water quality control standard in SY/T 5329—2012.
