Abstract: Disclosed is an electrocatalytic degradation device for organic wastewater, which includes an electrocatalytic oxidation reactor, a spray tower and a drying tower. The electrocatalytic oxidation reactor is provided with a hydroxyl generator, a catalyst filler and a box body. The box body of the electrocatalytic oxidation reactor is provided with a gas gathering device connected with the spray tower. An upper gas outlet of the spray tower is connected with the drying tower. The disclosure combines the electrooxidation reaction with the catalytic reaction to improve the electrooxidation efficiency of the electrocatalytic oxidation reactor and efficiently degrade the high salt high organic wastewater. The decomposed by-products are effectively utilized. The generated hydrogen is collected by the gas gathering device and enters the spray tower. The CO2 gas is absorbed after treatment. The CO2-removed gas passes through the drying tower to absorb moisture to obtain pure hydrogen.
