1. An electrocatalytic Fenton oxidation-electrochemical oxidation coupling process for efficient treatment of chemical wastewater, comprising an electrocatalytic Fenton oxidation step, an electrochemical oxidation step, and a pH adjustment step,
wherein an electrode in the electrocatalytic Fenton oxidation step is a tubular electrode,
wherein a current density is controlled to be 8-15 mA/cm2 and a spacing between an anode and a cathode is controlled to be 1-3 cm simultaneously in the electrocatalytic Fenton oxidation step so that oxygen produced at the anode reacts at the cathode to produce H2O2 with a mass concentration of 100-5,000 mg/L.
