| 摘 要： | 污泥龄作为维持活性污泥活性和新鲜度的重要指标已显示出比其他参数更重要。试验以校内生活污水为对象，通过污泥转移SBR工艺，研究了污泥龄分别为5、10、20、30d时，系统COD、NH4＋ -N、TN、PO4^3- -P的去除率以及污泥特性的变化。结果表明：污泥龄10d时，系统COD、NH4- -N、TN、PO4^3- -P去除率分别可高达81％、94％、62％、95％，并且系统沉降性能良好，系统整体脱氮除磷效果最优。

| Abstract: | Sludge age as a maintenance of the activity of activated sludge and an important indicator of freshness has been shown to be more important than other parameters. With domestic sewage as raw water, the paper presented the removal and sludge characteristics change of the system of COD, NH4＋-N, TN, pOg3--P when the sludge age is 5, 10, 20, 30 d by using the SBR process with sludge transfer. The results show that when SRT=10 d,the system gain the best removal of nitrogen and phosphorus, then COD,NH4＋-N,TN,PO4^3- - P removal rates were： 81% ,94% ,62% ,95%, and get the good performance of the settlement, the overall effect of the nitrogen and phosphorus removal system is excellent. |
