The invention discloses an electroplating comprehensive wastewater treatment process, and relates to the technical field of electroplating wastewater treatment. The electroplating comprehensive wastewater treatment process comprises the following steps: step 1, pretreatment of electroplating comprehensive wastewater, comprising (1) precipitating and sand filtering; (2) wastewater composition detection; step 2, classified catalytic oxidation of the electroplating comprehensive wastewater, comprising (1) for the electroplating comprehensive wastewater with a chemical oxygen demand less than 950 mg / L, adopting one-stage heterogeneous Fenton-like reaction as catalytic oxidation; (2) for the electroplating comprehensive wastewater with a chemical oxygen demand more than or equal to 950 mg / L, adopting two-stage heterogeneous Fenton-like reaction as catalytic oxidation; step 3, ion exchange of the electroplating comprehensive wastewater: adopting chelate resin to adsorb corresponding heavy metal ions. The electroplating comprehensive wastewater treatment process disclosed by the invention improves the requirement of the Fenton technology on pH value, enhances the catalytic oxidation effect, prolongs the service life of activated carbon, prolongs the resin supersaturation time, ensures that the effluent meets the standard, reduces the cost, is convenient to operate, and facilitates implementation of large-scale automatic wastewater treatment.
