It is attempted to increase both the solubility of ozone in solutions and the reaction efficiency of the system . The effects caused by the operating parameters including the reactor pressure, the hydroxyl ion concentration and the ozone gas flow rate were found. The analysis of reaction rate, mineralization efficiency and toxicity. this study. After the ozonation tests of the actual petrochemical wastewater, we can get the chemical oxygen demand removal efficiency and the changes on the biodegradability.
