Abstract
The present invention discloses a device for Fenton fluidized-bed process and a method applying the device for wastewater treatment. It belongs to the wastewater treatment field. The device comprises an adjusting tank, a lift pump and a main reaction column. The adjusting tank is connected to a water distributing trough on the top of the main reaction column through the lift pump; the main reaction column is filled with the packing material, and below the packing material is equipped with an obcone, whereon a plurality of inlets are provided and a slag discharge pipe is connected to the bottom; above the packing material is installed an inclined plate, above which and at the upper end of the main reaction column are arranged with a partitioned trough and an outflow trough; the partitioned trough is evenly divided by a vertical plate into two independent chambers; the upper end of each chamber is connected to the water distributing trough while the lower end of each chamber is designed with an outlet; the outlets of the two independent chambers are connected to the inlets on the obcone through the first circulation pump and the second circulation pump respectively; the outflow trough is installed opposite the partitioned trough. When being used to treat biotreated wastewater, the device disclosed in the present invention can enhance use efficiency of the reagent, and maintain high effect and stability in eliminating iron in the wastewater.
