摘　　要：采用活性炭、沸石、建筑陶粒及工程陶粒等作为生物滤池填料,考察了生物滤池对炼油厂废水中COD、NH_3-N、浊度的去除效果。实验结果表明,最佳的工艺条件为:水力停留时间1.5 h,进水有机负荷0.74～1.85 kg/(m^3·d),曝气量0.29 L/min。工程陶粒对COD和NH_3-N的去除效果最好,且出水浊度能达到废水回用标准,可作为生物滤池的填料。The removal effects of COD, NH3-N and turbidity from refinery wastewater in the biofilter were investigated using activated carbon, zeolite, architectural ceramic particles and engineering ceramic particles as biofilter packing. The experimental results show that the optimum process conditions are as follows ： HRT 1.5 h, influent organic loading 0.74 - 1.85 kg/（ m^3 · d）, aeration flow 0.29 L/min. Engineering ceramic particles can be used as the biofilter packing with the best removal effects of COD and NH3-N and satisfying effluent turbidity which can meet the standard for wastewater reuse.
