Integrated device for treatment of industrial wastewater

The utility model relates to an integrated device for the treatment of industrial wastewater, which comprises a pH adjusting device, an Electro-Fenton device, an oxidation stripping device, a flocculation device and a sedimentation device, which arranged in sequence, wherein the Electro-Fenton device comprises a reactor housing, a water inlet pipe and a water outlet pipe; a plurality of reaction chambers communicated in sequence are arranged in the reactor housing; the Electro-Fenton device further comprises Electro-Fenton units arranged in the reaction chambers; each Electro-Fenton unit comprises a power supply, a positive pole, a negative pole and a filler arranged between the positive pole and the negative pole; each positive pole is formed by connecting a plurality of positive plates in parallel; each negative pole is formed by connecting a plurality of negative plates in parallel; the positive plates and the negative plates of the same Electro-Fenton unit are arranged alternately and oppositely; the power supplies of the Electro-Fenton units in the reaction chambers are connected in series; each filler comprises a first filler made of iron-carbon alloy. According to the utility model, the improved multi-dimensional Electro-Fenton device is adopted, so that the defect that iron sulfide and organic carbon deposit are easy to settle on the surface of the electrode is overcome, the wastewater treatment effect is improved, the power consumption is decreased, and the treatment cost is reduced.
