Abstract

This paper explored the reservoir geology and characteristics of oil fields wastewater in Northern Shaanxi, and developed a new polysilicate complex (PsiC) coagulant. The coagulant is used to treat the oil field wastewater and the experimental results show that it exhibits better performances than PAC and FeCl₃ flocculants. After oil wastewater treated by PsiC, turbidity could be as low as 1 NTU, COD elimination rate is up to 85%, oil content is 10-14 mg/L and suspended substance (SS) content is 2-4 mg/L, which imply that the PsiC coagulant is more suitable for oil field wastewater treatment.
