管式膜处理聚合物驱采油废水的新型清洗技术与机理研究
Research on the new cleaning technology and mechanism of treating polymer flooding wastewater with tubular membrane
摘要
Abstract
In addressing the challenge of inefficient restoration of tubular membrane fouling in polymer flooding produced water(PFPW)caused by crude oil,inorganic salts,and refractory high-molecular-weight polymers(HPAM),this study introduces a novel cleaning technology incorporating CaCO3 powder as a synergistic clean-ing agent.Through systematic investigations of process parameters including CaCO3 powder dosing methods,dos-age,cleaning duration,flow velocity,and temperature on the cleaning efficiency of single-component cleaners(NaOH,NaClO,Na4-EDTA,and SDS),combined with quantitative analysis of membrane flux recovery(ηFR),the synergistic cleaning mechanism of CaCO3 powder was revealed to enhance fluid turbulence intensity and physical scouring effects.Results demonstrate that under optimized conditions(CaCO3 dosage:1000 mg/L,cleaning time:40 min,temperature:(40.0±0.5)℃,the ηFR increment was improved by approximately 50%on average compared to traditional single-component cleaning.Notably,the ηFR increment of the SDS-NaOH syn-ergistic system reached approximately 75%.关键词
