摘　　要：利用复合式曝气生物滤池(HBAF)处理合成洗涤剂废水,研究了水力负荷、气水比及滤层厚度对其处理性能的影响。结果表明,随着水力负荷的提高,COD、LAS的去除率迅速减小;最佳气水比为4∶1;处理出水的COD、LAS浓度与相应的滤层高度之间存在指数关系。在水力负荷为1.1 m3/(m2.h),气水比为4∶1的运行条件下,废水流经2 000 mm的滤层后,COD、LAS去除率分别为86%、81%,出水COD、LAS均能达到排放标准。The effects of hydraulic loading,gas/water ratio,and filter bed thickness on the treatment capacities have been studied by the experiments using hybrid biological aerated filter（HBAF） for treating the synthetic detergent wastewater.The results show that the removal rates of COD and LAS are reduced rapidly with the increase of hy-draulic loading,and the best gas/water ratio is 4∶1.There is an index relationship between the COD and LAS con-centrations and thickness of corresponding filter bed.Using HBAF for treating the typical detergent wastewater,the removal rates of COD and LAS can reach 86%,81%,respectively,under the following conditions：hydraulic loading is 1.1 m3/（m2.h）,and gas/water ratio is 4∶1,and after the wastewater flow through the filter bed whose thickness is 2 000 mm.Thus,the COD and LAS of effluent water can reach the discharge standard.
