摘要:: 以不同铁离子附载量的颗粒活性炭(GAC)在微波条件下对乳化油废水进行处理,通过正交试验,讨论了微波催化氧化处理乳化油废水的影响因素,并针对油去除率探讨了乳化油废水催化氧化动力行为.结果表明,微波作用时间是乳化油废水处理效果的主要影响因素,最佳工艺条件为:GAC上Fe离子附载量为33.32 mg/g、微波处理功率为720 W、微波处理时间为45 min,出水COD值及油含量达到排放标准.在乳化油废水的微波催化氧化处理过程中,油去除率与处理时间的关系满足一级动力学方程.

Abstract:: The emulsified oil wastewater was treated under microwave conditions with granular activated carbon (GAC) with different iron ion loads, and the influencing factors of microwave catalytic oxidation treatment of emulsified oil wastewater were discussed through orthogonal tests, and the catalytic oxidation dynamic behavior of emulsified oil wastewater was discussed according to the oil removal rate. The results show that the microwave action time is the main influencing factor of the treatment effect of emulsified oil wastewater, and the optimal process conditions are: Fe ion loading on GAC is 33.32 mg/g, microwave treatment power is 720 W, microwave treatment time is 45 min, and the COD value and oil content of effluent meet the discharge standard. In the microwave catalytic oxidation treatment of emulsified oil wastewater, the relationship between oil removal rate and treatment time satisfies the first-order kinetic equation.
