[0002] Multidimensional catalytic oxidation is an effective method for deep treatment of industrial wastewater, especially suitable for pretreatment of high-concentration wastewater. The basic steps of this method include pretreatment: the wastewater first enters the pretreatment tank, and the pH is adjusted to acidic by adding hydrochloric acid; multidimensional catalytic oxidation: the wastewater then flows into the multidimensional catalytic oxidation reactor, where multidimensional catalytic oxidation activated carbon and hydrogen peroxide are added, and oxygen is supplied by aeration, with a residence time of 30 minutes; sedimentation: the oxidized wastewater enters the sedimentation tank, coagulant is added and stirred, and the pH is adjusted with lime, and then allowed to settle; clear water discharge: the supernatant of the sedimentation tank is discharged and enters the clear water tank, and the concentrated sludge at the bottom is discharged to the sludge tank. Existing multidimensional catalytic oxidation high-concentration wastewater pretreatment is usually carried out in the pretreatment tank.
