%X Humic substance oxidation(HS) degradation by ozone was kinetically investigated. The effects of O3 dosage, initial pH, temperature and initial concentration of HS were studied. Under the conditions of 3.46 g·h-1 ozone dosage, 1000 mg·L-1 initial HS, 8.0 initial pH and 303 K temperature, the removal efficiencies of HS achieved 89.04% at 30 min. The empirical kinetic equation of ozonation degradation for landfill leachate under the conditions of 1.52 -6.10 g·h-1 ozone dosage, 250-1000 mg·L-1 initial HS, 2.0-10.0 initial pH,283-323 K temperature fitted well with the experimental data (average relative error is 7.62%), with low activation energy Ea=1.43×104 J·mol-1.
