摘　　要：实验研究了活性污泥与生物膜复合工艺(HP)对石化废水的处理效果,并与活性污泥工艺(ASP)进行对比研究。结果表明,HP对石化废水中COD的去除效果略好于ASP,而对NH3-N的去除效果明显优于ASP。另外,两种工艺对硫化物和油的去除效果类似。提高进水负荷时,HP表现出较强的耐冲击负荷能力。以2 L/h连续运行时,石化废水进水平均COD为895 mg/L,NH3-N为42.8 mg/L,硫化物为23.8 mg/L,油为47.1 mg/L,经HP处理后出水平均COD为116 mg/L,NH3-N为0.82 mg/L,硫化物为0.053 mg/L,油为12.1 mg/L,平均去除率分别为87.0%、98.1%、99.8%和74.3%。与ASP相比,HP还具有氧的利用率高、污泥产量及回流量少、动力消耗较低、运行管理方便等优点。Treatment of petrochemical wastewater using biofilm-activated sludge hybrid process（HP） was studied and compared with traditional activated sludge process（ASP）.The results showed that HP was slightly better than ASP on the removal of COD in petrochemical wastewater.HP was obviously superior to ASP on the removal of NH3-N.The two processes had similar removal rate of S2-and oil.When the influent loads increased,HP showed stronger resistance to shock loadings.When the inflow was 2 L/h and the average concentrations of COD,NH3-N,S2-and oil in the petrochemical wastewater were 895 mg/L,42.8 mg/L,23.8 mg/L and 47.1 mg/L,respectively,the average concentrations of COD,NH3-N,S2-and oil in the effluent of HP were 116 mg/L,0.82 mg/L,0.053 mg/L and 12.1 mg/L,respectively,and the average removal efficiencies of them were 87.0%,98.1%,99.8% and 74.3%,respectively.Compared with ASP,HP is of higher oxygen utilization ratio,reduced sludge yield,decreased reflux quantity,lower power consumption,and easier operation.
