摘要
采用气升式内循环间歇反应器(IC-SBAR)培养好氧颗粒污泥,考察了有机负荷分别为1.58和14.12kg/(m3·d)时所形成的好氧颗粒污泥的特性。结果表明,在两种负荷下反应器对COD、TN和TP的去除率均分别达90%、80%和90%左右,但高负荷下培养的好氧颗粒污泥的沉降性能较好。
An internal recycling sequencing batch airlift reactor was used to cultivate the aerobic granular sludge,and the characteristics of aerobic granular sludge at organic loading of 1.58 and 14.12 kg/(m^3·d) respectively were investigated.The result shows that the removal rate of COD,TN,and TP in the reactor reaches about 90%,80%,and 90% respectively at the two different loading,but the aerobic granular sludge at high loading has better settling performance.
