Ozone oxidation methods were used to treat the marine oil and gas pipelines washing wastewater． The effect of
various factors ( ozone dosing quantity、pH and inlet flow) on degradation of COD were investigated． On the basis of single
factor experiment，three factors including ozone dosing quantity、pH、inlet flow were designed and optimized by Design Expert
8. 0. 6， the quadratic polynomial model was obtained． Analysis showed that the model had a significant influence on the removal
rate of COD． The optimal reaction conditions were determined: The ozone dosing quantity was 9. 5 g /h，pH = 8. 92，inlet flow
was 2. 33 L/min． Under the optimum conditions，COD removal rate was 39. 21%，while the model predictive value of
38. 06%． The model was high goodness of fit with actual situation．
