The invention discloses a ternary electrolytic sewage treatment combined process and application thereof to petroleum and petrochemical wastewater treatment. The process comprises the steps of: successively conducting electrolysis flotation, electrolysis catalysis, electrolysis flocculation, precipitation separation, biological treatment, catalytic electrolysis flocculation and sedimentation separation on highly difficult wastewater, detecting the obtained water, discharging qualified water, and sending the sludge obtained in electrolysis flotation, sedimentation separation, biochemical treatment and precipitation separation to a sludge pool for sludge treatment. The electrolysis combined treatment process provided by the invention is a modular integrated treatment system, which can be combined flexibly according to the specific needs, so as to play the potential advantage of the sewage treatment steps to the greatest and cooperate with each treatment step to complete optimized treatment on various wastewater.
