Produced water from oil extraction is among the most challenging types of wastewater to treat in oil fields,consisting of various organic substances that are difficult to biodegrade and characterized by complex compositions.This paper employs grounded electrode atomization corona discharge technology for treating produced water from oil extraction.This involves utilizing high-voltage discharge to generate low-temperature plasma and reactive oxygen species,such as hydroxyl radicals·(OH),to decompose organic compounds,resulting in effective degradation.Multiple experimental setups are conducted to compare the effects of the presence or absence of an activated carbon layer on discharge current and treatment efficiency,as well as the impact of different activated carbon layer thicknesses and flow rates on purification efficiency.
