【 摘 要 】

Oilfield wastewater is the injection water from underground that brought to the surface during oil or gas extraction. It is generated in large amounts and has a complex composition, containing various toxic organic and inorganic compounds. Oilfield wastewater is currently treated in conventional methods such as phase separators, decanters and cyclones, which do not achieve more restrictive limitations related to the reuse of the effluent (reinjection into extraction wells). Therefore, advanced oxidation processes (AOPs) have been used in oilfield wastewater treatment for its excellent oxidizability. This review tries to provide an overview of AOPs for wastewater treatment. These oxidants include ozone, Semiconductor photocatalytic, Fenton and ferric iron. Optimum operating conditions and processing efficiency were also discussed.
