摘　　要：进水温度低会导致污泥量小以及硝化、反硝化效果差。试验在低温条件下研究了缺氧/好氧强化生物絮凝+变速生物滤池处理宿舍区生活污水的效能,考察了缺氧/好氧池不同HRT之比对CODCr、NH3-N、TN、TP和浊度等污染物去除的影响,首次通过灰色系统理论来综合评判,从而确定在该试验条件下缺氧/好氧池最佳HRT之比为3.6∶2.4。Low temperature of the inlet wastewater has bad influence on nitrification and denitrification, and also causes small quantity of sludge. Full-scale experiment was conducted on treatment of swage by anoxic/oxic enhanced bio-flocculation plus velocity changed bio-filter process, which has the purpose of investigating the performance of removal of CODcr, NH3-N, TN, TP and turbidity under different HRT ratios. The method of Grey System suggests that the optimal HRT ratio of anoxic/oxic is 3.6 ： 2.4 under the given conditions.
