The present invention relates to a hybrid fluidized-bed Fenton processing apparatus for treating a refractory wastewater, and more particularly, to a hybrid fluidized-phase Fenton processing apparatus for a refractory wastewater treatment system that includes a reaction tank having a reaction space therein, a wastewater supply unit for supplying wastewater, A main supply part for supplying the wastewater supplied from the wastewater supply part and the Fenton oxidizing material supply part and the main supply part for supplying the Fenton oxidizing material to the reaction tank, a large amount of the wastewater supplied from the main supply part, And a sediment discharging portion for discharging the sludge precipitated in the sludge generated in the reaction in the reaction tank, wherein the sediment discharging portion discharges the sludge discharged from the reaction tank, . According to the present invention, the wastewater contaminants are treated by the Fenton oxidizing material and the crystalline material, thereby improving the treatment efficiency and reducing the amount of sludge formed during the treatment. Can be saved.
