Abstract

Emulsified oil wastewater was treated on granule activated carbon (GAC) carrying different weight concentration Fe∼ion under the condition of microwave. Orthogonal experiment was designed to analyze the influence of microwave on treatment effect. And then, dynamic behavior of microwave catalysis oxidation for emulsified oil wastewater was discussed based on removal ratios of oil. The result shows that the main influential factor is microwave treating time. And the optimal conditions of experiment as follows: the weight concentration of Fe∼ion carried on granule activated carbon (GAC) is 33.32 mg/g, the power of microwave is 720w and the time of microwave treating is 45 min. After that, the value of COD and oil in effluent can reach emission standards. In addition, the dynamics of this reaction is a single order reaction when microwave catalysis oxidation was used to treat emulsified oil wastewater.
