Abstract：The degradation of MicrocystinLR (MC-LR) and COD was conducted by catalytic ozonation, and the reaction kinetics were investigated by direct substituting and dynamics differential methods. The results from direct substituting method indicate that the MC-LR degradation reaction fits well with secondorder kinetics, while COD degradation reaction fits well with firstorder kinetics. The results from dynamics differential method are consistent with the conclusions. The factors of temperature, ozone dose and pH value have influence on the degradation rate. Temperature has slight effect on the degradation rates of MC-LR and COD. Ozone dosage has significant effect on the degradation of MC-LR and COD, and the degradation rate constant is obviously increased with the increase of ozone dosage. The degradation rate is also sensitive to pH value, and the rate is quickly decreased under alkaline condition.
