摘　　要： 选择不同填料对生物接触氧化法处理生活污水进行了进一步的研究与应用,探讨了温度、接触氧化停留时间等因素对其处理效果的影响.实验研究结果表明,在水温为18℃～20℃,水力负荷为70ml/min时,采用鹅卵石和沸石的复合填料挂膜,进行生物接触氧化法处理生活污水,在降解NH3-N和氨氮等方面取得良好效果,COD、NH3-N去除率都高达80%以上. Further research and application have been carried out on civil sewage treatment with biological contact method through selective use of different fillings and the influence of different factors such as temperature, contact oxidation duration on the treatment effectiveness has also been discussed. The result of experiment research shows that NH3-N degradation result is good while treating civil sewage with biological oxidation method by use of cobble and zeolite mixed fillings under water temperature of 18℃- 20℃ and hydraulic load of 70ml/min, with improved COD and NH3-N removing rate as high as over 80%.
