The invention discloses a treatment process for high salinity organic wastewater produced during a seafood processing process, and belongs to the technical field of environment protection, The treatment process sequentially comprises a pretreatment workshop section, a primary coagulation workshop section, a primary acidolysis oxidation workshop section, a secondary coagulation workshop section, anelectrochemical oxidation workshop section, a secondary acidolysis oxidation workshop section, a filter pressing workshop section and a sludge treatment workshop section. According to the method provided by the invention, through chemical oxidation and electrochemical oxidation of a Fenton's reagent, the wastewater is treated in segments, organic matters in a water body can be effectively degraded, flocs are formed through a flocculating agent and a settling agent, and organic matters and solids in water are swept and adsorbed, so that the chromaticity, a pH value, COD and other indexes of afinal water body meet the emission requirement. The process has the characteristics of high treatment efficiency, stability in operation, and no fresh water resource occupation. After being treated through the process, indexes such as pH, SS and COD of salinity wastewater meet a B-grade requirement of the wastewater quality standards for discharge to municipal sewers (GB/T31962-2015).
