摘　　要：为研究弹性填料对ABR间歇启动的影响,采用有弹性填料ABR和无弹性填料ABR进行对比。结果表明,有弹性填料ABR的间歇启动时间比无弹性填料ABR缩短了8 d,弹性填料有利于缩短ABR的间歇启动时间和提高其COD去除率;弹性填料使ABR各个隔室内的pH有所上升,但上升的幅度并不大;弹性填料使ABR各个隔室内的ORP有所降低;弹性填料并没有对ABR各个隔室内的VFA产生较大的影响;弹性填料提高了ABR各个隔室内的碱度。This study was aimed to explore the effect of elastic filler on the intermittent start-up of ABR,ABR with elastic filler and ABR without elastic filler were compared.The result showed that the intermittent start-up time of ABR with elastic filler was 8 days shorter than that of ABR without elastic filler,the elastic filler was beneficial to shorten the intermittent start-up time of ABR and improve its COD removal rate;the elastic filler increased the pH in each compartment of ABR,but the range of increase was not large;the elastic filler reduced the ORP in each compartment of ABR;the elastic filler does not have a greater impact on the VFA in each compartment of the ABR;the elastic filler improved the basicity in each compartment of the ABR.
