Easily degradable high-concentration industrial wastewater treatment system

The utility model relates to the field of industrial wastewater treatment, in particular to an easy-to-degrade high-concentration industrial wastewater treatment system. The system comprises a pretreatment section, a high-concentration wastewater biochemical treatment device, a magnetic coagulation sedimentation tank and a disinfection tank, magnetic iron powder and activated carbon powder are added into a biological contact oxidation tank of the high-concentration wastewater biochemical treatment device, an aerobic filler and an aeration system are installed, and the concentration of dissolved oxygen in the tank is controlled to be 24 mg/L. The action of the magnetic iron powder and the active carbon powder penetrates through the biological and chemical reaction system, so that an adsorption micro-electrolysis environment can be formed, a huge specific surface area can be provided for the growth of microorganisms, the sedimentation rate of flocculent sludge is increased, the sludge loss and the process floor
