摘　　要：研究不同有机负荷下有弹性填料ABR和无弹性填料ABR对ABR处理生活污水的影响。结果表明,随着有机负荷的提高,两组ABR的平均COD去除率都有所上升;平均总氮去除率都有所提高,但提高的幅度并不大;平均总磷去除率都逐渐增加;平均SS去除率都逐渐降低。不同有机负荷下,有弹性填料ABR的平均COD去除率都高于无弹性填料ABR;两组ABR的平均总氮去除率很低,且相差很小;两组ABR的平均总磷去除率相差不大;有弹性填料ABR的平均SS去除率都高于无弹性填料ABR。弹性填料有利于提高ABR的COD去除率和SS去除率,对ABR总氮和总磷去除率的影响很小。The effect of elastic packing ABR and inelastic packing ABR on domestic sewage treatment under different organic loads were investigated.The result showed that with the increase of organic load,the average COD removal rate of ABR in both groups increased;the average total nitrogen removal rate increased,but the increase was not significant;the average total phosphorus removal rate increased gradually;the average SS removal rate decreased gradually.Under different organic loads,the average COD removal rate of ABR with elastic filler was higher than that of ABR without elastic filler;the average total nitrogen removal rate of ABR in both groups was very low and the difference was very small;the average total phosphorus removal rate of ABR in both groups was little different;the average SS removal rate of ABR with elastic filler was higher than that of ABR without elastic filler.Elastic filler could improve COD removal rate and SS removal rate of ABR,and had little effect on total nitrogen and total phosphorus removal rate of ABR.
