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
