摘　　要：采用泡沫分离-Fenton氧化工艺进行处理某炼油公司含SDBS和Brij30废水，研究了气体流速、废水流速、塔内液体高度、pH和Fenton试剂用量对处理效果的影响。得到了优化后的工艺条件为：Fenton试剂用量0．05mol／L，气体流速0．054～0．072m^3／h，分离塔内液体量为1．8～1．9L，废水流速2．0～2．2L／h，Fenton氧化处理pH=3-4。在此最佳工艺基础上进行了工业侧线实验，实验表明，采用泡沫分离-Fenton氧化工艺可将废水中SDBS和Brij30分别降至2mg／L和5mg／L以下。The waster water of a refining company, which contain sodium dodecylbenaene sulfonate （SDBS） and lauryl alcohol polyoxyethylene （Brij30） surfactants, were treated by the foam separation and Fenton oxidation process. The influence of air flow rate, waste water flow velocity, the liquid level in kettle, pH value and the Fenton reagent consumption were investigated. The optimal process conditions are as follows ： the consumption of Fenton reagent is 0.05 mol/L, air flow rate is 0. 054 -0.072 m3/h, quantum of waste water in separation tower is 1.8 -1.9 L, the water flow velocity is 2.0 - 2.2 L/h and the pH value of Fenton oxidation conditions is 3 - 4. The industrial lateral-line experiment was carry into execution under the optimal conditions. The results show that the foam separation-Fenton oxidation process can drop Brij30 and SDBS surfactants to 5 mg/L and 2 mg/L,respectively.
