摘　　要：采用生物膜-活性污泥复合工艺处理养猪废水,研究了该工艺的启动过程,分析比较了不同水力停留时间对污染物的去除情况。研究表明：随着水力停留时间的减少,各污染物的去除效果都有一定程度的降低,而氨氮容积去除负荷从（0.086±0.008）kg/（m3·d）增加到（0.170±0.038）kg/（m3·d）,最高可达0.22 kg/（m3·d）。本工艺的最佳进水容积负荷为0.07~0.12 kg/（m3·d）,此时NH＋4-N和COD的去除率分别为（94.18±2.78）%和（73.83±9.13）%。稳定运行期间出水NH＋4-N和COD基本都能满足GB 18596—2001《畜禽养殖业污染物排放标准》的要求。The piggery wastewater was treated by the combined biofilm-activated sludge A /O process.The strategies of the start-up process were studied and the effect of different hydraulic retention time（HRT） on the pollutants removal efficiencies was investigated.The results showed that the pollutants removal efficiencies had a certain decrease with the HRT decreasing.The ammonium volumetric removal loading increased from（0.086 ± 0.008） kg /（m3·d） to（0.170 ±0.038） kg/（m3·d）,and even could reach as high as 0.22 kg /（m3·d）.The optimum influent volumetric loading was 0.07 ~ 0.12 kg/（m3·d）,and the removal efficiencies of（94.18 ± 2.78） % and（73.83 ± 9.13） % for NH＋4-N and COD were achieved respectively.During the steady running process,the effluent NH＋ 4-N and COD could meet the requirements of ＂Discharge Standard of Pollutants for Livestock and Poultry Breeding＂（GB 18596-2001）.
