Abstract

Abstract:

Oxidation degradation and viscosity-breaking of polyacrylamide(PAM)in oil field sewage have been investigated by using K₂FeO₄ oxidant.The effects of K₂FeO₄ concentration,initial pH value,initial PAM concentration and reaction temperature have been evaluated.The results reveal that K₂FeO₄ is a strong oxidant,the rate of oxidation degradation of PAM isabove90%in60min,the effect of viscosity-breaking is also very obvious,and the viscosity of oil field sewage containing PAM isdecreased to the same level as that of distilled water in 15min

Key words: advanced oxidation, potassium ferrate, polyacrylamide, oxidation degradation, viscosity-breaking

摘要：

采用高价铁酸盐(K₂FeO₄)为氧化剂，对油田含聚丙烯酰胺的污水进行降解和降粘的研究，探讨了高铁酸钾投加量、初始pH值、初始浓度和反应温度对氧化降解以及降粘的影响。结果表明，高铁酸钾是一种高效的强氧化剂，氧化PAM降解率在60min时达90%以上;降粘性能也非常显著，在15min时含PAM污水的粘度可以降至与蒸馏水相近的粘度。
