摘要
高铁酸钾滤液中饱和的K2FeO4 和大量未反应的KClO具有强氧化性. 考察了K2FeO4 滤液对油田三元复合驱模拟污水的氧化降解效果及其稳定性. 实验结果表明,K2FeO4 滤液对含不同质量浓度的聚丙烯酰胺三元复合驱油田模拟污水的降解率大于60%,时间的变化对降解率的影响不大. K2FeO4 滤液具有较强的稳定性,适用于油田污水的处理.
Alkaline filter liquor of ferrates prepared by hypochlorite oxidation contains saturated FeO^(2-)_4 and ClO^-. Oxidative degredation of ASP-flooding wastewater with filter liquor of ferrate(Ⅵ) was tested. When it is used to treat the oilfield wastewater of produced fluids during ASP-flooding, more than 60% the loss of COD__(Cr) can be achieved. Filter liquor of ferrates is fitting for the processing of produced fluids during ASP-flooding, because it is stabl.
