Embodiment 1
[0060] Taking the MBR effluent from a landfill as the treatment object, the water quality indicators are CODcr 620mg / L, pH 7.8, conductivity 15.1ms / cm, and water volume 2m 3 / h. First, the built-in MBR effluent of the landfill digestion tank is sent to the leachate MBR effluent storage tank 1. cr The mass ratio is controlled at 14:1; the mass ratio of hydrogen peroxide dosage to ozone oxygen dosage is controlled at 1:100. The circulation ratio of the control circulation pump is 40%. The height ratio of the defoaming zone in the ozone catalytic oxidation tower to the ozone catalytic oxidation tower is 1:10, and the defoaming zone is filled with wire mesh defoaming packing; the height ratio of the first catalytic zone to the catalytic oxidation tower is 1:4, and the catalyst loaded is granular Noble Palladium Nickel Metal and MnO Supported on Polysilicic Clinoptilolite 2 The active component has a particle size of 4mm; the height ratio of the second-stage catalytic zone to th...
