利用厌氧/缺氧/好氧工艺与曝气生物滤池组成的双污泥强化反硝化除磷系统(AAO-BAF)处理生活污水,通过对比污染物的去除性能,分析了该系统除污染物性能的恢复情况。试验用反硝化除磷污泥在室温下放置了1个月。试验期间比较了两种启动方式,AAO反应器中厌氧、缺氧和好氧区的容积比(Vr)分别为2:5:2和2:6:1,记为1#和2#。试验结果表明,系统去除有机物和氨氮的性能基本没有恶化。第17 d,两种启动方式得到的TN和PO43--P的去除率分别达到了约75%和92%;去除单位NO-3-N吸收的PO43--P量也由试验初的0.5 mg PO43--P·(mg NO-3-N)-1增加到了1.5 mg PO43--P·(mg NO-3-N)-1左右。试验结果显示,AAO-BAF系统更适宜采用有利于除磷性能和污泥沉降性能快速恢复的方式1(1#)进行二次启动。

A two-sludge denitrifying-phosphorus-removal system, integrated anaerobic/anoxic /aerobic process with biological aerated filter (AAO-BAF), was used to treat domestic wastewater. By analyzing removal of COD and nutrients, the reactivation performance of AAO-BAF system was evaluated. The seed sludge with high content of denitrifying phosphorus accumulating organisms (DPAOs) had been deposited under room temperature for one month. Two start-up methods (denoted as 1# and 2#) were compared, for which the volume ratio of the anaerobic/anoxic/aerobic zone (Vr) of the AAO reactor was 2:5:2 and 2:6:1 respectively. AAO-BAF system exhibited good removal of COD and NH4+-N without obvious deterioration. At 17th day, TN and PO43--P removal reached 75% and 92% respectively with two start-up methods, while the amount of phosphate taken up per nitrogen denitrified increased from 0.5 to 1.5 mg PO43--P·(mg NO-3-N)-1. The results demonstrated that 1# was more suitable for the secondary start-up of AAO-BAF system, the corresponding COD, NH4+-N, TN and PO43--P removal efficiency reached 89%, 99%, 70%and 90%respectively at the 10th day. Furthermore, the results also showed that the sludge settling ability was also recovered more quickly for 1# than 2#.
